Cord-Reinforced Flexible Link Rotational Coupling Technology Offers a Solution for Conflicting Design Goals

To transmit torque in industrial drive systems, a compromise between a soft attachment for good noise, vibration and harshness (NVH) behavior, package, weight and a rigid attachment for low level of energy loss is necessary.

The presented research has culminated in a new technology in heavy-duty rotational power transmission coupling solutions comprised of a composite elastomeric rubber material reinforced with directional cording. This approach of employing composite flexible couplings offers development engineers the possibility of reduction of power loss and weight while improving package and easy maintenance.

These advantages are illustrated with a load and power density analysis as well as power fluctuations analysis.
