Universal Joint Max and Min Angles
Universal Joint Max and Min Angles
(OP)
I have a universal joint connecting an actuator to a valve, and I need to determine if it's installation location does not cause the joint to exceed the maximum angle for that type of joint. Does anyone have a good reference that would give minimum and maximum angles for proper operation of a universal joint? Is there a standard for this or does it depend on the geometry of the joint? If it is geometry dependant, do you have a formula for calculating the maximum angle? Thanks.

RE: Universal Joint Max and Min Angles
Automotive Hookes joints should be set at 4 degrees ideally.
Constant velocity joints have an articulation diagram based on angle AND plunge. The angle maxes out at 25 degrees, typically.

Lots of information available on u-joints in automotive applications. Try googling words like drive shaft, drive line angles, drive line u-joints, etc.
