Interface Introduces New Torque Coupling Guide

/0 Comments/in /by

The new Interface Torque Coupling Selection Guide is a valuable tool for determining the correct couplings for your specific transducer and application.

This resourceful guide considers the type of torque sensor you are using, the hub type, the paired sides for connection that is best suited for your test and measurement use case.

Our couplings are durable and made to sustain performance throughout the lifetime of the matching torque transducer’s high accuracy test and measurement conditions. Learn more in our Couplings 101 post.

Interface’s Torque Coupling Selection Guide will help you narrow down your choices and find the coupling that matches your application requirements. Interface Torque Transducer shafts are compatible with either a shrink disk or collar type hub. You have the option to choose from a shrink disk, keyed, keyed large, clamping ring, or a collar hub based on your shaft’s connection requirements. We do offer keyed shaft options for our torque transducers, by request through our custom solutions group.

The types of couplings Interface offers include:

  • Single Flex Floating Mount
  • Double Flex Pedestal Mount

These are offered with the following hub configurations:

  • Shrink Disk – Keyed
  • Shrink Disk – Keyed Large
  • Shrink Disk – Shrink Disk
  • Shrink Disk – Clamping Ring
  • Collar – Collar

Torque transducers require couplings to ensure accuracy and protect your sensor investment. A torque transducer coupling is a specialized coupling that is designed to connect a torque transducer to a rotating shaft and facilitate torque measurement. This ensures that the transducer can measure the torque accurately and reliably, without any damage to the transducer or the shaft. Read more in our post: Torque Transducers and Couplings are the Perfect Pairing.

Additional factors to consider when choosing a coupling:

  • Torque transducer model: Not all couplings are equal. Interface always recommends that the couplings are designed for the specific model to eliminate any concerns with performance and reliability. Go to our torque guide to review available models.
  • Torque range: The coupling must be able to handle the maximum torque that will be applied to it.
  • Speed: The coupling must be able to operate at the desired speed without overheating or causing vibration.
  • Environment: The coupling must be able to withstand the environmental conditions in which it will be used, such as temperature, humidity, and corrosive chemicals.
  • Space constraints: The coupling must be able to fit in the available space.
  • Quality: Interface provides couplings that are made for our specific torque transducers, ensuring they are engineered to the exact specifications of the paired sensor.

When selecting an Interface torque transducer, always request or include the Interface couplings that are designed for that specific transducer model. It is especially important to review the coupling’s features and make sure they are compatible with your transducer. The coupling and transducer are designed to work together, and using the wrong coupling could lead to problems or even damage the transducer.

Without a coupling, the torque transducer cannot be mechanically connected to the rotating shaft or component. As a result, it will not be able to measure the torque being transmitted through the shaft and you lose the ability to correctly monitor and analyze torque.

We always recommend that you connect with Interface’s application engineers if you have questions. Based on experience, they can help you assess your needs and make sure you choose the right coupling accessories.

Interface provides a series of guides to help in selecting the sensor, instrumentation and supporting accessories.  You can find all the online guides here, including the most popular guides:

Heavy Truck Test and Measurement Solutions

/0 Comments/in , /by

Interface is a trusted supplier to the vehicle industry. Manufacturers of vehicles and components rely on our sensor technologies for measuring force, torque, and weight. In the vehicle subsector of trucks, there are three main classifications of this type of vehicle based on weight: light, medium and heavy trucks, sometimes called heavy-duty.

Interface devices are commonly used in heavy-duty truck design and testing for various purposes, from structural to aerodynamic testing. Manufacturers use our load cells, torque transducers and instrumentation in testing labs to ensure vehicles meet regulatory and performance standards. Component and parts makers utilize our sensors and instrumentation for research, design, development and production, whether they are making brake pedals or tires.

Heavy Duty Truck Test and Measurement

  • Structural Testing: Interface products are used to evaluate the structural integrity and performance of truck components and systems. Load cells may be installed at critical points such as suspension mounts, chassis connections, and body attachments to measure forces and stresses experienced during static or dynamic testing. This helps engineers understand the load distribution, identify weak points, and optimize the design for enhanced durability.
  • Brake System Testing: Force measurement devices play a crucial role in assessing the performance and efficiency of a truck’s braking system. Load cells are commonly employed to measure the forces exerted on the brake pedal during braking maneuvers. This data helps evaluate braking performance, optimize braking force distribution, and ensure compliance with safety standards. Wireless load cells are growing in use for these types of tests. See: WTS Brake Pedal Force Testing
  • Tow and Haul Assessments: Determining a heavy-duty truck’s towing and hauling capabilities requires measuring the forces. Interface measurement devices are used to quantify the forces experienced by the vehicle during towing or hauling tasks. Load cells installed at key attachment points, such as trailer hitches or cargo beds, are used to measure the forces applied under different loads. This data aids in establishing safe operating limits and optimizing the truck’s design for maximum payload capacity.
  • Suspension Testing: Strain gage based sensors are frequently utilized to evaluate the performance of a truck’s suspension system and its impact on ride comfort. Load cells or accelerometers may be used to measure forces, vibrations, and accelerations experienced by the vehicle under various road conditions. This helps engineers optimize suspension settings, tune shock absorbers, and design suspension components that provide a balance between load-carrying capacity and ride quality.
  • Crash Testing: High-accuracy load cells and instrumentation are integral to crash testing heavy-duty trucks to evaluate occupant safety and structural integrity. Sensors are used to measure impact forces, accelerations, and deformations during controlled crash simulations. This data helps engineers assess the effectiveness of safety features, such as crumple zones and restraint systems, and improve the truck’s crashworthiness. Read: Vehicle Crash Test Load Cell Wall
  • Aerodynamic Testing: Measurement tools are employed to assess the aerodynamic performance of heavy-duty trucks. Load cells and systems used to measure the forces acting on the vehicle’s body, including drag and lift forces helps optimize the truck’s shape, reduce aerodynamic resistance, and improve fuel efficiency.

Another force that Interface has a great deal of experience measuring and helping our customers to monitor is load pulled or hoisted by components attached to trucks or other heavy machinery. As an example, Interface can measure the load capacity of a truck hitch to test the maximum capacity of an object it is pulling. It can also monitor the hitch in real time to ensure the load combined with the velocity of the vehicle or the gradient of a roadway is not creating a risk of failure.

In addition to testing the vehicles, safety standards exist for large, long and short haul trucks regarding their weight limits for most highway systems. It is why you often see weigh stations across the highway on road trips. Force sensors are often used in these types of weigh stations due to our product’s high capacities, accuracy, and reliability. Adversely, we also measure these types of vehicles capacity prior to hitting the open road to ensure the vehicle is designed to manage the amount of load in transport.

 

Suspension Testing for Heavy Duty Trucks

It is important to heavy duty track manufacturers to thoroughly test suspension. Automotive suspensions require fine tuning for best performance on various roads and conditions. Simulation of bumps, banking and other road conditions result in off-axis loading. Interface’s 1200-series load cell were mounted on top of each post in a 4-, 5-, or 7-post rig, which allowed them to measure forces during simulated driving. Moment compensating design of 1200-series load cells provide accurate readings during off-axis loading. This solution provides highly accurate (0.04%) measurement of loads applied to individual suspension points.

Truck Weighbridge

A customer owns a truck company and needs to record the weight or loads being carried by their trucks. They would like a wireless weighing bridge that is able to transmit, log, and display the results in real time. Interface suggested installing multiple WTS 1200 LowProfile™ Load Cells under a weighing bridge. When the truck drove over it, the load cells transmitted the force results wirelessly to the WTS-BS-4 Industrial Base Station connected to the customer’s PC with provided Log100 software. The WTS-LD2 Wireless Large LED Display also displayed the weight inside for the driver to see in real time. Using this solution, the customer was able to measure, log, and graph the different loads their trucks carried wirelessly onto the weighbridge with success.

Tire Testing for Semi-Trailers

A typical semi-trailer truck consists of a tractor unit with two front wheels and two sets of tandem axles at the rear, each with two wheels, resulting in a total of 18 wheels. By trade, 60,000-pound trailers needed at least three axles and 12 tires. Testing tires and mounting requires precision for these vehicles that are responsible for trucking goods and materials across the interstates and highways. A tire production company wants to put their tires under a stress test to research the dynamic control capabilities of their tires. Interface suggests using the AT105 Contactless Force and Torque Transducer to measure both the lateral force and torque of the tired being tested. Torque and force results can be displayed and graphed when connected to the SI-USB4 4 Channel USB Interface Module. After conducting a stress test on their tires, the tire production company was able to record and log the measurements of the torque and lateral forces implemented on their tires.

These are just a few examples of the types of test and monitoring solutions provides for trucks and other heavy duty vehicles. To learn more about our sensor’s capabilities in the automotive test and measurement markets, visit Automotive and Vehicle Solutions.

Torque Transducers and Couplings are the Perfect Pairing

/0 Comments/in /by

Torque transducers require couplings to enhance precision and reliability in performance. The pairing ensures accurate measurements. The coupling enables the torque transducer to precisely measure torque while maintaining a secure mechanical connection to the rotating components. This facilitates data collection, analysis, and control, leading to improved performance, efficiency, and reliability when using a torque transducer in various test and measurement applications.

Couplings are designed to provide a strong and secure connection between the shafts, ensuring efficient torque transmission while minimizing stress and wear on the components. They come in distinct types and designs, each suited for specific applications and operating conditions.

For example, rigid couplings provide a solid and inflexible connection between the shafts, allowing for precise torque transmission but offering little or no flexibility to compensate for misalignments. Whereas flexible couplings are designed to accommodate small misalignments and angular offsets between the shafts. They use flexible discs to provide some degree of flexibility, dampen vibrations, and reduce stress on the connected components.

Interface Torque Transducer Models T2, T3, T4, T5, T6, T7, T8, T11 and T25 offer a range of product-specific coupling options. It is important to note that couplings are not universal, and your best options are always the couplings designed for the specific model, thus the perfect pairing. To demonstrate the range of options, here is a quick list of coupling designs:

  • Floating Mount Keyed Single Flex Couplings
  • Pedestal or Foot Mount Keyed Double Flex Couplings
  • Floating Mount Clamping Ring Single Flex Couplings
  • Pedestal or Foot Mount Clamping Ring Double Flex Couplings
  • Floating Mount Shrink Disk Single Flex Couplings
  • Pedestal or FootMount Shrink Disk Double Flex Couplings
  • Floating Mount Single Flex Couplings
  • Pedestal or Foot Mount Double Flex Couplings

A torque transducer coupling is a specific coupling designed to facilitate the connection and torque measurement between a torque transducer and a rotating shaft, providing accurate and reliable torque data. Whenever you are selecting an Interface torque transducer, be sure to request or add the Interface couplings that are designed for that specific transducer model. It is especially important to review the couplings features that pairs with your specific transducer. They are designed to work together, and you risk any problems or potential transducer failure.

Torque Transducers Require Couplings for Accuracy and to Safeguard Your Investment

Without a coupling, the torque transducer cannot be mechanically connected to the rotating shaft or component. As a result, it will not be able to measure the torque being transmitted through the shaft. This means you will lose the ability to accurately monitor and analyze torque in the system.

Using couplings is a standard requirement when using a torque transducer. They provide the mechanical connection, transmission and reduce misalignments, which all contributes to accurate and reliable torque measurements with torque transducers.

A coupling provides a means of mechanically connecting the torque transducer to the rotating shaft or component from which torque is being measured. It ensures a secure and reliable connection between the transducer and the system under test. In the absence of a coupling, the torque transducer may not be securely attached to the rotating shaft. This can lead to relative movement or slippage between the transducer and the shaft,

The coupling enables the transfer of torque from the rotating shaft to the torque transducer. As the shaft rotates, the torque is transmitted through the coupling to the transducer, which measures and converts it into an electrical signal for further analysis or control.

A coupling helps to compensate for small misalignments between the shaft and the transducer. Without a coupling, any misalignment between the two components can put additional stress on the transducer and the shaft, potentially causing premature wear, increased friction, or even catastrophic failure.

Couplings can also provide vibration damping properties by design, as they absorb or dampen vibrations and shocks that may be present in the system. This helps to protect the torque transducer from excessive mechanical stresses and safeguards torque measurements. Without a proper coupling, the transducer may also be susceptible to excessive vibrations or shocks, increasing the risk of mechanical failure.

Torque Transducer and Couplings Applications

If you are looking at a torque transducer use case, assume there are couplings that are part of the application. To point out common examples of testing programs that utilize couplings with high-performance torque transducers, the first place to start is in the automotive industry. In the automotive industry, high-performance torque transducers with couplings are used for various testing purposes. For example, during the development and testing of engines, transmissions, and drivetrain components, torque transducers coupled with the rotating shafts allow for precise measurement of torque and power output. Torque measurement data is crucial for performance analysis, efficiency optimization, and durability testing.

Torque transducers with couplings are extensively utilized in the engineering, testing, and use of industrial automation, machinery and equipment. Manufacturing processes that involve rotating components, such as pumps, compressors, and turbines, are using torque transducers coupled with the shafts to provide measurements of torque. Accuracy in data helps monitor the efficiency of the machinery, detect deviations, and ensure standard operation. All of this contributes to preventative maintenance.

There are many R&D use cases where torque transducers with couplings are required. We often see torque transducers and couplings used in material testing and structural analysis. In the renewable energy sector, wind turbines and hydroelectric generators use torque transducers and couplings.

These examples the coupling enables the torque transducer to accurately measure torque while maintaining a secure mechanical connection to the rotating components.  To explore more about couplings, be sure to tune into our recorded torque transducers webinar.

Insights in Torque Testing Featured in Quality Magazine

/0 Comments/in /by

With the explosive growth in industrial automation and advanced manufacturing, torque measurement is a hot topic for test and measurement applications across a multitude of industries. We see demand rising due to the use in electric and autonomous vehicle testing, as well as in building components used in robotics and for spacecraft. Demand for torque transducers is so popular, Quality Magazine asked Interface’s product and custom solutions expert Keith Skidmore to contribute an article all about torque testing and how to get the most out of the transducer’s testing data.

Interface has a deep line of innovative torque transducers used where torque measurement is critical to the success of engineering and manufacturing products and components. We provide both an extensive array of standard transducers and custom torque solutions to be used in applications as large as rocket ships, to as small as measuring the torque on a bolt wrench.

Included below is a brief overview of Keith Skidmore’s contributed article in Quality Magazine outlining the basics of torque testing and providing examples of real-world applications of Interface products used to test and measure torque.

Getting The Most Out of Torque Testing

Torque is defined as the rotational equivalent of linear force. It’s a measure of how much a force acting on an object causes that object to rotate. This is one of the key measurements for engineers doing design, test, and manufacturing across a wide variety of industries where machines, vehicles, components and parts include a spinning or rotating motion. It’s critical to understand how to measure torque if you’re doing product development with these types of systems such as engines, crankshafts, gearboxes, transmissions, and rotors.

The incredibly wide variety of torque transducers, different types of devices and tests and the accompanying accessories necessary for different projects can make it difficult to determine what is needed for each individual application. For instance, torque tests are often used in the automotive industry to assess engine torque and speed, but the products used can differ between a typical gas vehicle and newly introduced electric vehicles. Torque is also frequently used to test the tightness of a variety of lug nuts and screws, which is an entirely different measurement solution.

This article provides a brief overview of the key considerations when planning for a torque test. It includes the different types of torque testing, the different torque sensor styles, accessories, mounts, and other tips and tricks. It also provides a brief overview of the potential applications of torque tests with pictures.

The article goes on to provide the basics of torque testing, as well as providing real world applications of torque test and measurement. Here is a preview of one of the applications included in Keith’s contribution to Quality Magazine. To read the article in its entirety, please click the link here.

Engine Dynamometer Testing

In this application example, a rotary torque transducer is used to measure the speed and torque of an engine. This rotary transducer can sense the torque of the engine with high precision and provide an electrical output that is converted from an analog to a digital signal. A rotary transducer is necessary due to the spinning element involved in the engine. It’s paired with a very high-quality coupling and is mounted in a fixed position. Both are necessary to account for the high speeds used in the test. This application would allow the user to measure both torque and speed of the engine simultaneously, which will provide valuable data in confirming the design of the engine or determining if it needs to be adjusted for the vehicle it will drive.

Interface Solutions for Testing Tools

/0 Comments/in /by

Interface load cells, torque transducers and instrumentation are commonly used in the test and measurement of different tools and fasteners used in testing products and actual production of various machines and components. The sensor data received in measuring assembly tools and fixtures used in securing nuts, bolts, and screws, is critical in making safe and reliable products.

For example, the ability to measure torque on screws and the force output of a screwdriver or wrench is very important when there are tight tolerances involved like in engineering and build of automotive or aerospace and defense machines and parts.

As we did for the machine testing blog, we’ve detailed a few examples of how Interface force and torque solutions are used in measuring tools performance for both design and assembly.  You can find additional application notes on these examples and more by visiting our industry solutions.

Bolt Fastening Force and Torque

An aerospace company was working on a test plan that involved taking torque and compression measurements on fasteners with varying joint materials. The system required both high and low sampling rates, in addition to the capability of precisely measuring force and torque simultaneously. They required reliable accuracy and long-term stability. The test plan intended to provide verification of required force and torque specifications for fasteners, to ensure safety without compromising installation. Interface suggested a LW or LWCF Load Washer in conjunction with a  T12 Square Drive Rotary Torque Transducer. With this solution, the customer was able to align force and torque measurements to desired levels. This was accomplished by combining the sensors with the high sample rate of the data logging and graphing capabilities of the SI-USB, capturing real-time force and torque levels for examination. The fasteners were tightened to the specified force and torque requirements and were safely installed without impairment to themselves or the joint material. The customer was able to measure the rapid event effectively and accurately. Read more about this bolt fastening solution here.

Aircraft Screwdriver Fastening Control

An airplane manufacturer needed a solution where they can control the torque when fastening screws on their airplane models. They didn’t want to create any damage to materials or apply too much torque when plane components are being fastened together. Interface suggested a T15 Hex Drive Rotary Torque Transducer, which can be attached to the fastening work bench, measuring and recording torque, rotational speed, and angle of the screwdriver. The LWCF Clamping Force Load Cell is installed, measuring the forces applied on the screw being fastened. Results are sent to the SI-USB4 4-channel USB Interface Module, which is connected to the customer’s PC or laptop where data is logged, graphed, and displayed. This solution allowed the airplane manufacturer to calibrate their screwdriver by measuring its torque, rotational speed, and angle, when attaching materials together for their airplane. They were also able to measure the forces being applied to the screw, to ensure it was not applying too much torque to the components. You can learn more about the aircraft screwdriver application here.

Ratchet Wrench Torque Verification

A customer wanted to perform regular torque testing on his ratchet-type torque wrench while recording these values for future examination. Interface supplied a model TS15 Square to Flange Reaction Torque Transducer with the INF-USB3 PC Interface Module for the customer to use. The customer mounted TS15 to work bench through flange and inserted the ratchet-type torque transducer into the TS15. Using this product, the customer was able to accurately perform their calibration checks and view the results while logging them to their PC Computer.  Learn more about this wrench torque verification testing here.

While not nearly as complex as machine testing applications, tools testing is equally important to the outcome of a project. The tools and fasteners used, even those as simple as a bolt and wrench, need to be accurately measured and assembled to avoid loose connection or overtightening that can damage the product. Interface provides a host of tool testing solutions for nearly anything that outputs force or torque. To learn more about our tool testing solutions, visit us at www.interfaceforce.com.

Wind Tunnel Testing

A major aerospace company was developing a new airplane and needed to test their scaled model for aerodynamics in a wind tunnel, by measuring loads created by lift and drag. Interface offered a Model 6A154 6-Axis Load Cell which was mounted in the floor of the wind tunnel and connected to the scaled model by a stalk. A Model BX8-AS was then connected to the sensor to collect data. The wind tunnel blew air over the scaled model creating lift and drag, which was measured and compared to the theoretical airplane models. Software in the PC converted raw data signals to actual force and torque values at the stalk. Using this solution, the company was able to analyze the collect data and made the necessary adjustments in their design to improve the aerodynamics of their theoretical airplane models. Read more.

Garbage Truck On-Board Weighing

A garbage disposal company wanted to test the load capacity of their garbage truck bins so they know when it reached maximum capacity. Interface’s solution was to customize and install 4 SSB Sealed Beam Load Cells under the garbage box body, on either side. When trash continues to be piled inside the box body, it will push more force down onto the SSB Sealed Beam Load Cells. When maximum load capacity has been reached, the results can be reviewed and displayed when connected to the 482 Battery Powered Bidirectional Weight Indicator in real time. With this system, the customer was able to test the maximum load capacity of the garbage bin attached to the truck, so they know when to empty the truck’s garbage at the transfer station. Read more.

An industrial automation company was building an automated assembly machine for an auto manufactur­ing plant. They needed to tighten all head bolts on an engine on their assembly line to a specific torque value. Having the head bolts precisely and consistently tightened to the engine block is critical to the operation of the engine. Several Interface Model T33 Spindle Torque Transducers were installed in their new machine to control torque, angle, and ensure the head bolt was properly tight­ened. The square drive of the T33 allowed the customer to fix their tool directly to the end of the torque sensor, streamlining the installation. When the machine comes down and screws on the engine head bolts the torque and angle profile are sent to the customer’s machine controller. Based on the feedback received by the machine controller, the automation will pass the engine to the next step in the assembly line or fail and have the engine evaluated further. This allowed the customer to ensure the head bolts were correctly installed according to manufacturer specifications, producing an engine that meets performance and reliability expectations of the auto manufacturing plant.

Bicycle Load Testing

A mountain bike manufacturing company wanted a system that measures their bike frames load capacities and vibrations on the frame. They also want to ensure the bike’s high quality and frame load durability during this final step of the product testing process. Interface suggested installing Model SSMF Fatigue Rated S-Type Load Cell, connected to the WTS-AM-1E Wireless Strain Bridge, between the mountain bike’s seat and the bike frame. This will measure the vibrations and load forces applied onto the bike frame. When a heavy load is added to the seat, the SSMF Fatigue Rated S-Type Load Cell measures the vibrations and load forces applied to the bike to indicate any stress points through a number of cycles. The results will be captured by the WTS-AM-1E and transmitted to the customer’s PC using the WTS-BS-6 Wireless Telemetry Dongle Base Station. This solution helped the mountain bike manufacturing company gather highly accurate data to determine that their bikes met performance standards through this final testing cycle. Read more.
