Efficiency of u-joints
Efficiency of u-joints
(OP)
Sorry for such a base question.
But could someone tell me a ball park figure for the mechanical efficiency of a U-joint?

RE: Efficiency of u-joints
I think the way to work it out is to figure out the load in the bearings, and then for your joint articulation angle and speed you can work out a surface speed for each bearing, and then using a coefficient of friction of 0.1-0.3, you can work out the power lost. I've never done that.
