Simulation of contact force of involute gear meshing
摘要
Abstract
In order to obtain the changing pattern of contact force of involute gear meshing, a computation method based on dynamic simulation was proposed.The dynamic model of involute gear meshing was established and the computation method for contact force of gear meshing based on Hertz theory was also introduced.With the dynamic model, the contact force and the frequency spectrum of gear meshing, x direction and y direction were simulated.The simulation results show that the amplitude of the contact force of gear meshing changes obviously.From the moment of meshing approach and meshing recess, the experience of contact force is from 0 kN to maximum and from maximum to 0 kN.Frequency multiplication of 1 and 2 of meshing frequency are in the frequency spectrum of contact force.The contact force of gear meshing of x direction and y direction changes obviously with explicit frequency modulation, and the frequency of rotation and frequency of meshing are in the frequency spectrum.The carrier wave is the meshing frequency of gear and the modulation wave is the rotary frequency of gear.The contact force of gear meshing ofx direction and y direction has the same frequency spectrum and phase difference of 90°.关键词
