Abstract The grease lubrication process can be divided into a “churning” and “bleed” phase. In this paper it will be shown that the churning phase consists of two other phases: a “channeling” and “clearing” phase. During channeling, by far most of the grease is pushed sideways, making a “grease channel”. This happens very quickly. During the clearing phase, churning continues but now with only a small and constant volume of grease. The transition from the clearing to the bleed phase is characterized by a sudden decrease of grease volume in the running track. The end of the churning phase and therefore of the clearing process is determined by a critical energy.

油脂润滑滚动轴承中的搅拌过程：窜槽和清理

摘要 脂润滑过程可分为“搅拌”和“放气”阶段。在本文中，将显示搅动阶段包括另外两个阶段：“引导”和“清除”阶段。在通道期间，大部分油脂被推向侧面，形成“油脂通道”。这发生得非常快。在清理阶段，搅拌继续进行，但现在只有少量且恒定的油脂。从清理阶段到放气阶段的过渡的特点是运行轨迹中的润滑脂量突然减少。搅拌阶段的结束以及清除过程的结束由临界能量决定。
