摘要

针对弧齿锥齿轮轻质重载的特点

利用有限元方法的批处理功能进行了考虑边缘接触的轮齿接触分析

定量讨论了边缘接触随载荷增加时的变化规律。根据考虑边缘接触的几何接触分析

将齿轮从进入啮合到退出啮合分成若干步进行计算

每一步的计算结果连接起来用于描述整个啮合的过程。以一对弧齿锥齿轮为例

经过不同载荷条件下考虑边缘接触的定量分析

提取出接触应力、接触印痕、接触路径

并与几何接触分析和承载接触分析结果进行了对比

三者吻合度较好。对比结果证明

通过有限元法分析可以较精确地确定齿轮发生边缘接触时的载荷临界值及边缘接触位置

得出边缘接触会导致接触应力急剧增大、接触路径延长、接触区域面积变大的结果

通过定量计算、比较各项参数指标得出变化规律。

Abstract

According to the lightweight and heavily loaded characteristics of spiral bevel gear

spiral bevel gears with tooth edge contact were analyzed by finite element processing batch

and the change regulation of tooth edge contact as load increases was quantitatively discussed. On the basis of tooth contact analysis

gear meshing processions were divided into several steps to calculate. Each step was combined to describe the gear meshing processions. Taking a pair of spiral bevel gears as an example

tooth edge contact is analyzed under different load conditions. The contact stress

contact pattern and contact trajectory were obtained by post-treatment

which well coincide with tooth contact analysis and loaded tooth contact analysis. The result shows that three tooth edge contact parameters listed above steeply rise as loads passing beyond the critical value. And the change characteristics can be obtained by quantitative calculation and parameter comparison.
