摘　　要：考虑润滑油膜在阶梯轴承出口区运动接触表面上滑移而避免润滑油膜在轴承其他表面上滑移,给出了阶梯轴承润滑油膜承载能力和摩擦系数分析结果。算例得出,在一定工况下这种轴承的承载能力因界面滑移略微提高,而其滑移表面摩擦系数却因界面滑移略微下降。Considering the boundary slippage at the moving surface in the bearing outlet zone but the boundary slippage absent at the other bearing surfaces, the paper presents the analytical results of the load - carrying capacity and friction coefficient of a hydrodynamic step bearing. The calculations show that in certain operating conditions, because of the boundary slippage, the load - carrying capacity of the bearing can be slightly improved and its friction coefficient at the slipping surface can be slightly reduced.
