An arrangement by which one part may be made to move freely in all directions while rotating with another part.
A joint that transmits rotary motion between two shafts not in a straight line. Depending on its design, a universal joint can accommodate a large angular variation between its inputs and outputs.
coupling that connects two rotating shafts allowing freedom of movement in all directions; "in motor vehicles a universal joint allows the driveshaft to move up and down as the vehicle passes over bumps"
a mechanical connection between rotating shafts which are
Coupling that allows one shaft to rotate at an angle to another without vibration.
A joint that can swivel in any direction whilst at the same time transmitting torque. This type of joint is commonly used in propeller shafts and some driveshafts, but is not suitable for some applications because the input and output shaft speeds are not the same at all positions of angular rotation. The type in common use is known as a HardySpicer, Hooke's or Cardan joint.
A joint that transmits rotary motion between two shafts that aren't in a straight line.
A joint designed to transmit torsional effort from a given length of shafting to another independent of alignment.
In animation, a joint that can rotate only about any two of its local axes. A human wrist is a good example of a universal joint (although a wrist has limitations on the extent it can rotate).
A universal joint, U joint, Cardan joint, or Hardy-Spicer, Hooke's joint is a joint in a rigid rod that allows the rod to 'bend' in any direction. It consists of a pair of ordinary hinges located close together, but oriented at 90° relative to each other.
