摘  要:
齿轮的实际润滑状态为兼具完全弹流润滑和边界润滑的混合弹流润滑。通过推导混合弹流润滑下齿轮的平均滑动摩擦因数,结合弧齿锥齿轮的几何接触特性与承载接触特性,计算其瞬时接触椭圆长轴上各点的滑动摩擦功率损失,拟合了啮合周期内的滑动摩擦功率损失函数,经过积分运算得到了混合弹流润滑下弧齿锥齿轮传动的啮合效率。通过与格利森公司计算锥齿轮传动啮合效率的方法对比分析,表明该方法计算正确且精度高。

摘  要:
The average sliding friction coefficient was derived in the mixed elastohydrodynamic lubrication state,with complete elastohydrodynamic and boundary lubrication.Based on the geometry and load contact characteristics of spiral bevel gears,the sliding friction power loss of each point on the long axis of the instantaneous contact ellipse was calculated.Meanwhile,the function of sliding friction power loss in a meshing period was established.The meshing efficiency of spiral bevel gears was calculated by integrating the function under the condition of mixed elastohydrodynamic lubrication.This algorithm was demonstrated to be correct and precise compared with Gleason corporation's method of calculating the meshing efficiency of bevel gears.
