螺旋锥齿轮润滑仿真研究与分析

Simulation Research and Analysis of Spiral Bevel Gear Lubrication

本文主要研究螺旋齿轮接触面摩擦受力问题和润滑问题。在近代机械润滑理论基础上,借助于有限元分析软件ANSYS对于齿轮啮合状态进行瞬态仿真分析,在齿轮初始接触有冲击的条件下,分析研究齿轮各个接触面在不同工况下的受应力情况。之后,再利用润滑油膜仿真理论进行实验,借用郑绪云的点接触膜厚公式和弹流润滑机理,构建计算方程计算齿轮接触面间油膜厚度的变化规律。

This paper mainly studies the friction force and lubrication problem of the contact surface of the helical gear.On the basis of modern mechanical lubrication theory,with the help of finite element analysis software ANSYS,the transient simulation analysis of gear meshing state is carried out.Under the condition that the initial contact of the gear has an impact,the stress of each contact surface of the gear under different working conditions is analyzed and studied.After that,the simulation theory of lubricating oil film is used to conduct experiments,and the formula of point contact film thickness and the elastohydrodynamic lubrication mechanism of Zheng Xuyun are borrowed to construct a calculation equation to calculate the variation law of oil film thickness between gear contact surfaces.
