Zero-Max CD Couplings Provide High Torsional Stiffness for Torque Transducers and Test Machinery

Zero-Max.jpg

CD Couplings from Zero-Max are utilized in Torque Transducer and Test Machinery to ensure accurate torque readings and test accuracy. The setup pictured shows Double-Flex CD Couplings used with a “fixed” mount Torque Transducer on a Test Stand for performing accelerated testing.  

June 24, 2022

Torque Transducers and Test Machinery experience extreme demands including high torque loads and high operating speeds which cause stress on connected components. To assure these systems generate accurate test data when experiencing these conditions, system designers specify CD Couplings from Zero-Max. 

Utilizing Zero-Max’s proprietary Composite Disc-Pack (CD), CD Couplings are unique in design and provide the ideal combination of operating characteristics that improve the accuracy of torque measurements. The key characteristics of the Composite Disc design are: (1) high torque capacity, (2) high torsional stiffness, and (3) low reaction loads under misalignment. Following are the coupling’s operating features:

• CD Couplings provide the high torque capacity needed for torque transducers. They can be sized to the required torque for a specific test. Or the coupling can be sized to the overload capacity of the torque transducer so the transducer and test equipment can be re-purposed for other testing.

• CD Couplings provide the needed high torsional stiffness so that accurate position and torque readings can be obtained. High torsional stiffness is especially important for tests that involve rapid speed and/or direction changes.

• CD Couplings include a unique open-arm disc pack design that increases misalignment capacity and minimizes any reaction loads imparted to the torque transducer and connected test components under misalignment. Low reaction loads are important since torque transducers, by design, have reaction load limitations. This coupling feature ensures accurate and precise test readings.

• To handle high test speed applications and avoid resonance, CD couplings may be dynamically balanced.

CD Couplings designed for Torque Transducer and Test Machinery applications may be custom designed to the specific needs of the test machine and can be adapted to shaft-mount or flange-mount transducers. Zero-Max offers engineering services and decades of experience to help ensure the ideal design. Popular options include in-house dynamic balancing capabilities and a complete selection of shaft tolerances and shaft connections including keyless, keyed, splined, and other shaft designs.
