Spiral bevel gear true tooth surface precise modeling and experiments studies based on machining adjustment parameters

摘要

The true tooth surface of a spiral bevel gear is not the standard spherical involute surface, since the microscopic tooth surface varies according to machining adjustment parameters, with different tooth contact forces, stress distributions, and other intrinsic properties. Therefore, it is necessary to propose the method whose advancement and feasibility can be verified by gear cutting and contact pattern experiments, to obtain a precisely digitized true tooth surface of spiral bevel gear based on machining adjustment parameters, which will lay a solid foundation for subsequent true tooth contact analysis, transmission error analysis, gear cutting, etc.
