面齿轮传动的承载接触分析

为了促进高性能面齿轮传动技术的发展.对点接触面齿轮传动进行承栽接触分析.建立了点接触面齿轮传动的坐标系,推导了传动中接触点方程,实现了传动中面齿轮上接触点位置的仿真.利用曲面上任意点处主曲率的计算方法,得到了传动中圆柱齿轮和面齿轮上接触点处主曲率的变化规律.根据布希涅斯克问题的求解方法,给出了传动中面齿轮上接触区域的椭圆长、短半径、中心最大变形量、最大压应力以及载荷分布的方程,分析了接触中心最大压应力的变化规律,实现了接触斑点的可视化仿真.

Load Tooth Contact Analysis on Face Gear Driver

To accelerate the development of the face gear drive, the load tooth contact analysis (LTCA) of the face gear diver is considered. The coordinates are built for the point contact face gear drive. Ac-cording to the enveloping method, the equation of the contact points on the face gear is deduced. By the solution method of the principal curvature and Boussinesq problems, the equations of the contact characteristics of the contact points on the face gear are developed. Based on the equations, the contact spots on the face gear are simulated and analyses are conducted on the rule of the principal curvature of the contact points on the pinion and the face gear as well as the rule of the maximum press stress of the con-tact areas on the face gear.
