考虑箱体刚度耦合的齿形修整研究
Modifying Gear Shape Coupled with Housing Stiffness
摘要
Abstract
To improve tooth pair meshing quality,we propose a method for determining the parameters for gear shape modification,which takes the housing stiffness into consideration.We establish the simplification algorithm for calculating gear shaft bending and torsional stiffness so as to determine the initial values of parameters of the longitudinal gear shape modification.We use the ANSYS to establish the finite element model for analyzing the contact of gears with a shaft.Using the finite element model,we simulate the gear meshing stiffness and determine the initial values of the parameters of involute modification and longitudinal modification without considering housing stiffness.Finally we propose our simplification algorithm for extracting the housing stiffness matrix,which is then coupled with the gear shaft,thus optimizing the gear shape modification parameters coupled with housing stiffness.The simulation results show that our method can greatly improve the load distribution on tooth surface,indicating that our method is effective.关键词
