A common joint, often known as a U-joint or Cardan joint, is a mechanical element that permits the transmission of torque between two shafts that aren’t aligned. Common joints are generally utilized in automotive functions, akin to drive shafts and steering columns, in addition to in industrial equipment and robotics. There are a number of kinds of common joints, together with single U-joints, double U-joints, and fixed velocity (CV) joints. The kind of common joint utilized in a specific software depends upon the particular necessities of the applying, such because the angle of misalignment, the torque load, and the pace of rotation.
Common joints are necessary parts in lots of functions as a result of they permit shafts to transmit torque at angles that may not be attainable with strong shafts. This makes them important for functions the place shafts should be aligned at angles, akin to in drive shafts and steering columns. Common joints additionally enable for some misalignment between shafts, which could be attributable to elements akin to manufacturing tolerances, put on, and vibration.
