摘要：

综合研究齿面间的宏观因素和微观因素对齿轮接触面间的应力状态的影响,建立轮齿齿面间的应力分析与计算分形模型,该模型能准确计算齿面的接触应力,并能解决微线段齿轮内接触的应力计算问题。分析了各参数对模型计算结果的影响趋势,给出了一对渐开线齿轮接触强度计算的三种理论方法对比分析,结果证明了分形理论应用于齿轮接触强度计算的有效性。

Abstract:

A fractal model of calculating and analyzing the contact stress between two gears was set up after synthetically studying the stress state infected by the microcosmic characteristics and macroscopical factors.This model can accurately calculate the contact stress of gears, and resolve the caculation of inner contact problems of micro-segment involute gears. And then different calculation results were presented and varying with the main parameters.At last, three theoretical approaches to get the contact stress of a pair of involute gears were given,and through the contrasting analysis about the three ways , it is proved that appling the fractal theory in calculations of gears’ contact stress is valid.

Key words: gear, , stress analysis, , fractal, , contact model
