FEM Analysis for Bending Strength of Active Gear Design

摘要

Gear design is based on the standard gear rack parameter in modern gear design. This makes gear design indirect and passive. However, the standard rack parameters have certain limitations on gear parameters and performances. Some good designs with nonstandard parameters are excluded. In order to meet practical requirements and improve the stress performances, a active gear design method is proposed in this paper. 3D gear modal is designed basing on active design method by PRO/E software. The bending stress of tooth root which is affected by gear shaft and tooth width is analyzed by FEM software ANSYS. This paper has a certain reference value for the gear design with high performance.
