Problems solved by technology

[0009] Aiming at the existing technical problems, the present invention proposes a revised method for analyzing the meshing characteristics of gear pairs considering the modification of the drum direction, which solves the complex and heavy modeling process in the prior art, low calculation efficiency, and the requirement for computer performance. Higher, the calculation result has a large error, and cannot truly reflect the meshing characteristics of the gear pair and other issues

Abstract

The invention relates to an amended gear pair meshing characteristic analysis method taking drum modification into consideration. In order to acquire basic parameters of a gear pair and drum modification parameters, gear teeth of the gear pair are divided into N independent even web gears in the direction of tooth width; the time-variant meshing stiffness of each web gear pair is calculated by adopting the gear pair meshing characteristic analysis method taking prolonging the meshing influence into consideration on the basis of the error of a gear profile of a drum modification gear pair; a meshing gear pair three-dimensional model comprising drum modification is established through three-dimensional drawing simulation software, the three-dimensional model is guided into an ANSYS software to create a three-dimensional finite element contact model, and time-variant meshing stiffness data in the whole meshing process of the gear are solved. The analysis method is simple in modelling process and low in calculated quantity, the requirement on a computer is low, and the calculation result is accurate and true.

Description

technical field [0001] The invention belongs to the technical field of mechanical dynamics, and in particular relates to a modified method for analyzing the meshing characteristics of a gear pair in consideration of bulging modification. Background technique [0002] At present, there are mainly two methods for the analysis of the meshing characteristics of gear pairs considering the drum shape modification: [0003] 1. Based on commercial finite element analysis software [0004] Import the 3D CAD model into the commercial finite element analysis software or directly build the 3D model in the finite element software, select the appropriate unit and material parameters, mesh the 3D model, establish the finite element contact model of the meshing gear pair, and set the appropriate Constraints and choose an appropriate solution method to analyze the meshing characteristics of the gear pair. However, when the existing commercial finite element analysis software is used to ana...
