基于载荷当量安装误差的面齿轮振动特性

Considering the support structure deformation and tooth elastic deformation of the face gear drive, a multi degree of freedom coupling vibration analysis model including equivalent installation errors was established by converting the transmission deformation into installation errors. Fourth order Runge-Kutta method was adopted to solve the differential equation of face gear drive. The influences of equivalent installation errors on the vibration acceleration and the dynamic meshing force of the face gear were obtained. The dynamic characteristics experiments for face gear drive were performed. The experimental results showed that the vibration acceleration along x direction caused by offset and shaft angle error was larger than that along z direction. The influence of vibration acceleration along x direction caused by offset error was larger than that caused by shaft angle error.
