Spur gears with longitudinal tooth profile modification mesh creating which is suitable for stress analysis

摘要

Presented article contains description of meshing procedure applied by authors for preparation of discrete spur gears models used in stress analysis with ABAQUS computer program. Described procedure was successfully applied for meshing of single spur gear sector crown. This sector includes one tooth and two parts of side tooth spaces. Such form of mesh allows to build models including any part of spur gear crown up to full one. Sector based structure of the discrete domain allows to reduce the computation time. Developed special computer program based on presented procedure is a fully functional tool and allows fast preparation of meshes for different set of parameters describing spur gear geometry inclusive longitudinal tooth profile modifications. All meshes presented in this article were prepared with developed by authors mesh generator.
