Stress simulation and analysis method for gear drive

Abstract

Provided is a stress simulation and analysis method for gear drive. The method comprises the following steps: carrying out parametric modeling on a gear through UG and making simulation analyses of stress of gear nodes in ANSYS software, and calculating the maximum contact stress of the gear. The data obtained by finite element calculation is close to theoretical analysis results with errors in the allowance range, which indicates that a model is established accurately and a finite element analysis process is reasonable. By parametric modeling and design of the gear, repeated modification of the main design dimensions of the gear is avoided. The stress simulation and analysis method for gear drive has the following beneficial effects: according to the design requirement, the required gear model can be obtained only by changing main parameters such that CAE of the gear becomes easier and the design process of the gear becomes easier and more convenient.

Description

technical field [0001] The invention relates to the technical field of gears, in particular to a stress simulation analysis method in gear transmission. Background technique [0002] The compact gear transmission has the characteristics of stable transmission ratio and high efficiency. It is widely used in mechanical transmission, and the transmitted power can reach hundreds of thousands of kilowatts. These are the advantages that other transmission methods cannot replace. There are many types of gear transmission devices. The gear materials are hard or brittle, and the mechanical properties and heat treatment processes of the materials are also different. Therefore, the failure modes of the gears during the transmission process include tooth fatigue fracture, tooth surface abrasive wear, plastic deformation, etc. When designing gears in engineering, two commonly used criteria are generally adopted for the easily-produced damage forms. For gears that mainly produce pitting o...
