摘要
以面齿轮传动系统为研究对象,考虑载荷作用下面齿轮传动系统中支撑结构变形和轮齿弹性变形,通过将传动系统变形等效到面齿轮和直齿轮安装误差方向,建立包含当量安装误差的面齿轮多自由度耦合振动分析模型;采用4阶Runge-Kutta法求解了面齿轮传动系统运动微分方程,得到了当量安装误差对面齿轮振动加速度和法向动态啮合力的影响;开展了面齿轮动态特性测试试验,试验结果表明:偏置距误差和轴交角误差引起的面齿轮沿x方向振动加速度大于沿z方向振动加速度;偏置距误差对面齿轮x方向振动加速度的影响大于轴交角误差。
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 xdirection caused by offset and shaft angle error was larger than that along z direction.The influence of vibration acceleration along xdirection caused by offset error was larger than that caused by shaft angle error.
