Influence of Vibrational Loads on Needle Skew in Cardan-Joint Bearings

The influence of vibration on the operation of cardan joints is studied. An equation is derived to describe the oscillation of the needle’s skew angle in bearings under the action of the variable torque from vibrational forces. In both dynamics and statics, this angle is found to depend on the dimensions of the joint and on the load applied to a single needle in the operational zone of the bearing.
