基于圆柱齿轮设计中齿数优化的探索与分析

摘要

旨在深化探索一种齿数优化配置方案，以此来找出分散失效风险，增加圆柱齿轮使用寿命的方法。提出两个重要的新名词--轮齿啮合循环周期和啮合散布度。啮合散布度实际是度量了齿轮系统中某个齿在相对的齿轮中啮合的数量的多少，当值取100%时，说明该齿在运转中与相对的齿轮的每个齿都会发生啮合状态。%This paper delved into one allocation plan of teeth number optimization, in order to ifnd a way to scatter the failure risk and increase the cylindrical gear’s service life. There have been brought in two new important nouns: Teeth-Meshing-Cycle and Dispersal Degree of Meshing (DDOM). DDOM actually measure the amount of meshing between one tooth and the corresponding gear in gear system. When is equal to 100%, it explain that the tooth in operation, will mesh all teeth of the corresponding gear.
