摘要

保持架为球笼式等速万向节的重要部件,当球笼式等速万向节处于极限角度时保持架为危险部件,因此极限角度下保持架的强度是否满足需求对其设计制造非常重要。通过试验以及仿真的方法对保持架强度进行研究,首先在极限角度、极限扭矩条件下进行仿真获得保持架应力状态并确定危险部位。然后通过保持架扭转静强度试验获得保持架在极限角度下的破碎扭矩。最后运用显微硬度计对保持架进行硬度测试,通过硬度强度转换关系获得保持架沿厚度方向的强度分布规律,结果表明保持架强度满足要求。此研究可以为保持架设计及制造提供技术依据。

Abstract

Cage is one of the key components of constant velocity joint.The cage is in the dangerous situation when the CV joint in the limit Angle,thus the strength of the cage under the limit Angle plays an important role in meeting the requirements for the design and manufacturing.The strength of cage was studied by experiment and the finite element simulation.First of all,stress state and dangerous area were obtained through simulation under the condition of the limit Angle and torque.The fracture torque of the cage was studied by torsion test.Finally,the hardness of the cage was measured by the micro hardness tester,and the distribution regulation that the strength of the cage was obtained by the transformation of the hardness and strength.The results show that the cage strength meets the requirements.This study can provide technical basis for design and manufacturing.
