时变摩擦因数对弧齿锥齿轮动力学特性的影响
Effect of Time-varying Friction Coefficient on Dynamics of Spiral Bevel Gears
摘要
Abstract
A generalized 3—dimensional multi—DOF dynamics model for spiral bevel gears was proposed and the influence of time—varying friction coefficient on the gear dynamic responses was analyzed. Mixed EHL model was also proposed to predict the instantaneous friction coefficient at each contact grid cell along the contact zone. The comparison results to published empirical friction coefficient formulae show that mixed EHL model can predict friction coefficient more accurately.Lastly,comparing to time— varying friction coefficient, constant friction coefficient and without friction case, the simulation results of dynamic meshing forces and dynamic transmission errors are demonstrated that sliding friction and time- varying friction coefficient have greater effects on dynamics of spiral bevel gears.关键词
