Interface Introduces New Torque Coupling Guide

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:

Interface Solutions in the World of Sports

With our headquarters in the golf capitol of the U.S., it is easy to see why Interface test and measurement solutions rank top for engineers and golf manufacturers to test the force of golf balls, range equipment, clubs, and even the carts that roam the course. But our sensor technologies have a much broader reach, in both sport and geography.

Why is force measurement so heavily involved in the making and designing of sports equipment? It is obvious even by definition; sports are considered an activity involving physical exertion and skill in which an individual or team competes against another or others for entertainment.

The physical exertion often utilizes some type of apparatus, device, tool, material, equipment, or gear that requires measurement of tension, compression, or rotation. Every sport differs and type of testing also will vary, whether from initial fatigue testing or actual designing sensors into the fitness equipment like a treadmill.

Our force measurement sensors are used across a wide variety of sports equipment to evaluate performance, lifecycle, durability, and quality.

Our specialty is building high accuracy solutions for the testing and monitoring of parts and total systems that move and create force, which is vital to makers and product designers of sports equipment and machines. Our force measurement solutions are ideal for stand-alone testing rigs, production equipment, as well as to embed in sports products in order to increase operability and reliability for end users.

Interface force measurement solutions are commonplace in sports gear and equipment R&D labs, design houses, manufacturer test and production facilities. The range of products we provide is as broad as the variety of sport categories, both individual and team. This applies to products used by consumers, as well as by professional athletes, trainers, and pro sport teams. We also collaborate with several engineers and manufacturers that build exercise and training equipment.

Interface has a history of providing our low profiles, s-types and miniature load cells for testing products used in individual sports such as running, weightlifting, mountain climbing, skiing, skating, bowling, fishing and cycling.

Golf Club Swing Accuracy

Golfers undergoing training or practice wanted a system that will monitor and record their striking accuracy and swing movement. Interface created a custom made SSB Sealed Beam Load Cell that can be attached in line with the golf handle. When a golf ball is struck, force measurements are recorded, logged, and graphed using the WTS-AM-1E Wireless Strain Bridge Transmitter. The results transmit directly to the WTS-BS-6 Wireless Telemetry Dongle Base Station when connected to the customer’s PC or laptop. Using this solution, the customer was able to successfully record, graph, and log a golf player’s striking accuracy and swing movement with Interface’s wireless force system. Read more here.

Mountain Bike Load Testing

A mountain bike manufacturing company wanted a system that measures their bike frames load capacities and vibrations on the frame. They want to ensure the bike’s high quality and frame load durability during this final step of the product testing process for their future consumers. 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. 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. With this system, the mountain bike manufacturing company was able to gather highly accurate data to determine that their bikes met performance standards through this final testing.

Golf Ball Tee Testing Machine

A customer wanted to ensure their golf ball automatic tee mechanism is working for their consumers- both buying their tee’s for home use or for golfing ranges. They needed a system that will sense the presence of a golf ball, which will trigger and automatically dispense new golf ball to the tee. Interface’s WMC Sealed Stainless Steel Miniature Load Cell was installed within the golf tee, which would measure the golf balls pressure on the tee when loaded or unloaded. This load cell is electrically connected to the motor which initiates the cycle to release another ball onto the tee. Force measurements can be measured using the 9330 High Speed Data Logger when connected to the customer’s PC or laptop. With Interface’s products, the customer was provided a force solution that was able to measure the presence of a golf ball on their auto-tee machine. Get more information here.

These are just a few examples of Interface’s work in the sporting goods and fitness industry. If it moves, rotates, pushes, or pulls, chances are that Interface has a solution that can help perfect the performance. To learn more about our work in sports and consumer goods.
