A universal joint is a mechanical connection between rotating shafts which are generally not in parallel but intersecting. “U-joints” transmit torque and motion. U-joints are used in a variety of applications, wherever handling significant angular misalignment is the main focus. Common u-joints by design have difficulty compensating for parallel offset and axial misalignment. Cardan types also introduce rotational inconsistencies into drive systems, a phenomenon known as “non-constant velocity rotation.” The HELI-CAL® Flexure is an advanced and unique u-joint solution that generally exceeds the capabilities of common u-joint designs. A HELI-CAL® u-joint is really a flexure capable of over 5°of angular misalignment. It may accommodate up to 90° of angular misalignment in certain circumstances. This type of u-joint will also compensate for axial and parallel misalignment. Learn more with our “Flexure Tech Tips”.
