外齿轮润滑泵无困油时齿面润滑状态的研究

Study of Lubricating State on Meshing Surface in External Gear Lubrication Pump Without Regard to Trapped Volume

外齿轮润滑泵的齿轮传动有别于常规的齿轮传动,其原因主要在于油膜存在入口压力、出口压力和载荷的与众不同。从刚性等粘度润滑理论入手,针对无困油时外齿轮润滑泵的齿面润滑分析,建立出油膜包含入口压力和出口压力的压力分布公式;据此,根据实例计算出的膜厚比,判断出齿面确实存在着流体润滑状态的可能性,这与实际情况比较符合。最后,文章总结了一些结论及指出下一步继续研究的方向。

The gear transmission of external gear lubricant pump was different from conventional gear transmission;the reason was oil filminess on meshing point of meshing gear had an inlet pressure and discharge pressure and a larruping load.In order to analysis lubricant state of gear surface of external gear lubricant pump without regard to trapped volume,the thesis established a study of pressure distribution formula including inlet pressure and discharge pressure based on rigidity isoviscous theory.According as t...
