Abstract

The triangle mesh model for tooth surfaces of spiral bevel gears is established based on the coordinates of three dimensional discrete points of mesh surface. Considering the full tooth surfaces’ dynamic contact relationship, the three dimensional contact dynamics model of spiral bevel gears is constructed and the dynamics analysis method is studied based on Multi-body Dynamics Theory and Compliant Contact Dynamics. The collision detection for triangle–triangle elements based on bounding volume hierarchies and DAE numerical simulation method are used to simulate contact dynamics characteristics of spiral bevel gears transmission. The influences of single surface contact, double surface contact of meshing teeth, loads and backlash to the dynamic contact forces in full surface of meshing teeth and dynamic response are analyzed. The results revealed that the new method and dynamic model brought out in this paper preferable simulate the characteristics of carrying capacity and contact dynamics of spiral bevel gears. The method and simulation results provide valuable theoretical basis for further research on dynamics analysis and design of spiral bevel gear and gear transmission systems.
