齿轮润滑油泵的润滑状态分析

Analysis of lubrication condition on gear lubrication oil pump

由斯特莱贝克曲线可知,在油润滑下,两个相对运动物体表面分为三种润滑状态.通过计算,齿轮润滑油泵工作时齿面处于混合润滑状态,齿面有磨损产生.而实际观察可知,齿轮润滑油泵齿面没有磨损,齿面处于流体润滑状态.

Stribeck curve divides the lubrication condition of the surface of two opposite movement bodys into three sections.Through calculation tooth faces of gears whose lubrication oil pump is working are in the condition of mixed lubrication and wear can occur.By observing practicing,wear is not on the tooth.surface of gear in lubrication oil pump ,and it is in condition of fluid lubrication.A new calculating method should be set up for production.
