The spiral bevel gear is commonly used for aviation and vehicle industry. The meshing characteristics of the spiral gears are depending on the connection between microscopic shape and macroscopic dynamic performance, so the lubrication state of the tooth surface greatly affects the contact and meshing of the tooth surface. This paper takes the meshing characteristics of spiral bevel gears under boundary lubrication as the research object, the tooth surface meshing stiffness and normal displacement as the performance indicators to establish the dynamic model of bending-torsion-shaft coupling of spiral bevel gear transmission by using the centralized parameter method, to analyze the problem of the continuous change of friction and normal meshing force during the meshing process of spiral bevel gears. Meanwhile, the friction coefficient between the gear meshing teeth surfaces and the dynamic meshing stiffness were further obtained. Then, the dynamic equations were solved by using the variable-step Runge-Kutta method and it could be concluded that the dynamic meshing force, coefficient of friction, and normal relative displacement being in a steady state. The results indicate that the average dynamic meshing force is 20.1 kN, and the coefficient of friction is 0.11 with boundary lubrication. The average normal relative displacement is 70.0280 µm and the fluctuation range is between 70.0264 µm and 70.0303 µm. Finally, the solved results were verified by simulation.

摘要

The spiral bevel gear is commonly used for aviation and vehicle industry. The meshing characteristics of the spiral gears are depending on the connection between microscopic shape and macroscopic dynamic performance, so the lubrication state of the tooth surface greatly affects the contact and meshing of the tooth surface. This paper takes the meshing characteristics of spiral bevel gears under boundary lubrication as the research object, the tooth surface meshing stiffness and normal displacement as the performance indicators to establish the dynamic model of bending-torsion-shaft coupling of spiral bevel gear transmission by using the centralized parameter method, to analyze the problem of the continuous change of friction and normal meshing force during the meshing process of spiral bevel gears. Meanwhile, the friction coefficient between the gear meshing teeth surfaces and the dynamic meshing stiffness were further obtained. Then, the dynamic equations were solved by using the variable-step Runge-Kutta method and it could be concluded that the dynamic meshing force, coefficient of friction, and normal relative displacement being in a steady state. The results indicate that the average dynamic meshing force is 20.1 kN, and the coefficient of friction is 0.11 with boundary lubrication. The average normal relative displacement is 70.0280 µm and the fluctuation range is between 70.0264 µm and 70.0303 µm. Finally, the solved results were verified by simulation.
