摘要

斜齿圆柱齿轮在啮合过程中

其啮合接触线的总长度不是定值

而该值将影响啮合过程中轮齿间的线载荷

因此分析了斜齿轮对在一个啮合周期内的接触线总长度的变化规律。目前将斜齿轮转化为当量直齿轮计算齿轮齿面接触强度

无法反映啮合瞬时齿面接触应力分布情况。将啮合接触线两侧的斜齿轮轮齿对看做曲率半径不断变化的圆锥台体

并结合斜齿轮啮合原理、赫兹弹性接触理论

通过解析法计算轮齿对任意啮合时刻的齿面接触强度

并分析了轮齿对一个啮合周期内齿面接触强度的变化规律。通过有限元分析软件

对解析法的计算结果进行了验证。

Abstract

The total contact line length isn’t a constant value during a meshing period of helical gear pair. However the length will have an affect on the linear load which acts on helical gear pair

so the variational law of contact line length during a meshing period is analyzed.Now the contact strength of helical gear is calculated by equivalent spur gear method

but this method can’t reflect contact strength distribution of arbitrary meshing moment.The teeth of helical gear pair along contact lines are thought as cone body

according to meshing theory of helical gear and Hertz elastic contact theory

the contact strength of arbitrary meshing moment is calculated by analytical method

and the variational law of contact strength is analyzed during a meshing period. The calculated result of analytical method is verified by FEA method.
