考虑磨损的十字轴式万向联轴器可靠性评估
Reliability assessment of cross-shaft universal joint considering wear
摘要
Abstract
In order to prevent the issue of transmission efficiency decline or even failure in universal joint caused by wear,the wear amount was calculated based on the Archard model and Hertz contact theory.the functional relationship between the variation amplitude of the output angular velocity and the wear amount was given by using dynamic simulations,and a reliability and sensitivity calculation model was established.The results show that greater wear leads to greater fluctuation of the output angular velocity,with a significant increase in fluctuations once the wear amount exceeds a certain threshold.As the wear amount increases,reliability gradually decreases,and the sensitivity of reliability to each random variable is negative,with the parameter KH having the highest sensitivity.Therefore,while regularly monitoring the wear amount and the variation amplitude of output angular velocity,appropriate process measures should be taken to improve material hardness and use high-quality lubricants to reduce the mean and dispersion of KH.关键词
