摘要

为预测直齿锥齿轮瞬态啮合效率,根据当量齿轮原理,将锥齿轮等效为当量直齿圆柱齿轮,通过计算膜厚比判定润滑状态,并建立边界润滑、弹流润滑及混合润滑下的摩擦因数模型。综合考虑啮合点相对滑动速度、法向载荷等时变性因素的影响,并在齿轮啮合周期内采用双重积分的方法,以啮合线压力角、接触点节圆半径为参数建立锥齿轮滑动摩擦功耗以及滚动摩擦功耗模型,计算锥齿轮啮合总功耗,并通过MATLAB软件对锥齿轮啮合功耗进行仿真分析。

Abstract

In order to predict the transient meshing efficiency of bevel gear pairs,a theoretical model of friction coefficient is established under boundary lubrication,elastohydrodynamic lubrication and mixed lubrication based on the principle of equivalent gear theory,by simplifying bevel gear into equivalent straigh gear,and by computing oil film-thickness ratio. Considering the impact of transitioning factor of mesh point relative sliding velocity,normal load,and friction coefficient,a computing model of friction power losses for bevel gear is established,the math model of sliding and rolling friction power loss is established with a variable of pressure angle and pitch radius by double integration for a meshing cycle,and the simulation analysis of mesh power losses of bevel gear is carried out based on MATLAB.
