Abstract

The invention discloses a gear strength checking method. A finite element analysis method is adopted to analyze and calculate contact stress and tooth root bending stress of an involute standard cylindrical spur gear. In addition, in finite element analysis, AYSYS software is subjected to secondary development, that is, an APDL language is applied, and parameter accurate modeling, self-adaptive mesh generation and finite element strength analysis of the gear are automatically achieved. The method is good in modification effect and high in accuracy.

Description

technical field [0001] The invention relates to the technical field of advanced manufacturing and automation, and relates to a gear strength checking method. Background technique [0002] As an important transmission part that is often used in mechanical structures, the strength of gears directly affects the working performance and life of the entire mechanical structure. However, in traditional gear design, the strength verification process and design process of gears are mainly through manual design. Complete, the calculation is cumbersome, the design cycle is long and it is difficult to achieve optimal design. Contents of the invention [0003] The present invention solves the above problems in order to solve the above problems, thereby providing a gear strength checking method. [0004] The purpose of the present invention is to provide a gear strength check method, 1) gear strength analysis, use the finite element analysis software ANSYS to analyze the strength of th...
