摘要
现代发动机比功率的提高,使得发动机的交变载荷明显增加,发动机轴瓦的摩擦损耗导致轴瓦疲劳破坏的问题较为常见,所以轴瓦的润滑状态对其疲劳寿命有很大影响。在传统设计中对此类问题的影响研究较少,本文从理论上对该问题形成的原因以及解决办法进行了探讨。
With the improvement of modem engine Power Ratio, Causes the engine＇ s AC load obvious increase. This questions to be common that engine bearing Friction loss causes the Bearing fatigue failure. So, Bearing Lubrication on the fatigue life has a great impact. In traditional design, the study such issues is less,This paper discussed this issue, In order to discuss the reasons of and find the solutions to this problem.
