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 a modified meshing characteristic analysis method of a gear pair considering the modification of the drum direction. The method is to obtain the basic parameters of the gear pair and the modification parameters of the drum direction, and decompose the teeth of the gear pair into N parts along the tooth width direction. Independent and uniform sheet gears, based on the tooth profile error of the drum-shaped modified gear pair, the meshing characteristic analysis method of the gear pair considering the influence of extended meshing is used to calculate the time-varying meshing stiffness of each sheet gear pair; through the three-dimensional drawing simulation software Establish a three-dimensional model of the meshing gear pair containing drum-shaped modification, import the three-dimensional model into ANSYS software to establish a three-dimensional finite element contact model, and solve the time-varying meshing stiffness data in the entire meshing process of the gears; the analysis method of the present invention has a simple modeling process, The amount of calculation is small, the requirements for the computer are low, and the calculation results are 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...
