Cardan Joint – Universal Joint – Shaft Cross and Yoke

universal coupling, U-joint, Cardan joint, Spicer or Hardy Spicer joint, or Hooke's joint

Interactive animation of a Universal Joint, which demonstrates the interaction between the forks and the crosshead, to change the direction of rotation of the axis in a Cardan Axis.

Cardan Axis- Universal Joint

Basically, the Universal Joint is composed of two forks, sometimes called forks, ears, etc., and a cruciform piece called a crosshead. Each axis of the crosshead allows a fork to rotate around it. This combination allows the Cardan Shaft to change the direction of the rotation axis without changing the direction of rotation.

Tips:

The interactive arrows allow you to change the speed of the axis rotation for easy viewing;

The left arrow slows down until the rotation stops;

– With the Universal Joint stopped, clicking the smaller arrows allows for smooth positioning;

Observation:
I’m working hard to convert the animations to HTML5, and with this one is no different, for now, please see the dynamics of a Universal Board in this video.
