汽车驱动桥螺伞齿轮疲劳寿命试验规范剖析

Anatomy of Fatigue Life Test Specifications about Rear Axle Spiral Bevel Gear

概述了国内外部分汽车驱动桥螺伞齿轮疲劳寿命试验规范,并对相关规范进行了剖析。结果表明美国G公司规范和国内QC/T533—99标准中关于螺伞齿轮疲劳寿命试验的试验条件较苛刻,且与实际工况存在一定差距;美国R公司和欧洲I公司规范中的试验条件与实际使用工况比较接近。

This paper summarizes fatigue life test specifications of rear axle spiral bevel gears in rear axles at home and abroad, and analyzes the relative specifications.The results of anatomy and analysis have shown that conditions of fatigue life test specifications about rear axle spiral bevel gear in G company USA and QC/T 533-99 standards in China are more strict,and there is difference with practical situation.The test conditions in R company in USA and I company in Europe are close to practical situation.
