齿轮过盈配合在工程中一直被广泛使用。由过盈配合产生的预应力对齿轮的强度和寿命影响很大。本文针对某发动机过盈装配的曲轴齿轮进行了基于刚度模型和有限元法的分析 ,得出齿轮内径、过盈量与预应力的关系 ,为采用过盈配合齿轮的设计提供借鉴
Gear interference with the project has been widely used. Prestressing caused by interference fit has a great influence on the strength and life of gears. Based on the analysis of stiffness model and finite element method, the relationship between gear inner diameter, interference and prestress is analyzed in this paper, which is used to design an interference fit gear
