Description

technical field [0001] The invention relates to a test bench for testing the kinematics and dynamic parameters of a non-centering universal joint under the conditions of large deflection angle and large torque, in particular to a tripod non-centering universal joint Test Bench. Background technique [0002] The non-centering universal coupling is a new type of constant angular velocity universal coupling newly developed in recent years, which not only overcomes the non-constant angular velocity characteristics of the cross shaft universal coupling, but also overcomes the existing Ball cage type universal couplings and ball fork type universal couplings have the disadvantages of complex manufacturing process and high manufacturing cost, but have the advantages of simple structure, low processing and manufacturing cost, and good manufacturability. With the increasing number of applications of universal joints and the improvement of required precision, the study of the motion ...
