Influence of machining deflection error on contact specialties of face gear drive

摘要:

为了对点接触正交面齿轮传动中加工偏置误差的影响进行分析,建立考虑加工偏置误差影响的点接触正交面齿轮传动坐标系,并推导传动中接触点方程,分析加工偏置误差对正交面齿轮齿形及其传动中接触点位置的影响;根据曲面上任意点处主方向和主曲率的求解方法,分析加工偏置误差对传动中接触点处主曲率的影响;根据布希涅斯克问题的解法,推导传动中正交面齿轮上接触点处接触特性方程,并分析加工偏置误差对传动中接触点处最大压应力的影响.研究结果表明,点接触正交面齿轮传动的接触特性对正交面齿轮的加工偏置误差不敏感.

Abstract:

To analyze the influence of machining deflection error on contact specialties of the orthogonal face gear drive,the coordinates of the points contact orthogonal face gear drive is built up and the contact points equations are deduced.Based on these equations,the change of tooth shape,the contact point position,and the maximum press stresses on the orthogonal face gear are analyzed.According to the solution method of the principal curvatures,the influence on the principal curvatures at the contact points is also analyzed,and by the solution method of the problem of Boussinesq,the contact specialties equations are developed.Results show that the contact specialties of the orthogonal face gear are not sensitive to the machining deflection error.
