Kinematic Analysis of Tripode Joint 811325

Tripode Joints are said to be Constant Velocity Joints, but in actual employment, they have some velocity fluctuation. Analysis was made of the effects of the twist of the intersecting planes, 120° dividing errors and deviation of the pitch radius on the velocity fluctuation and the joint design. Instead of the conventional tripode joints with half side variable pitch radius (HVPR) profile, the tripode joints with both side variable pitch radius (BVPR) profile have been proposed, which remarkably reduce velocity fluctuation and provide more design freedom.
