Oil Film Characteristics and Power Consumption of Slipper Pair Under Redundant Pressing Force

Sun Yi1,2 Jiang Ji-hai1,2 Liu Cheng-qiang1,2(1.School of Mechatronics Engineering,Harbin Institute of Technology,Harbin 150080,Heilongjiang,China; 2.The State Key Laboratory of Fluid Power Transmission and Control,Zhejiang University,Hangzhou 310027,Zhejiang,China)  
In the consideration of the supporting force of wedge due to the high-speed rotation of the slipper,a model describing the oil film under the slipper of the piston pump in the presence of redundant pressing force is crea-ted by solving high-degree differential equations.Then,the dynamic characteristics of the oil film under above-mentioned conditions are described through Matlab programming.Moreover,the relationship between the oil film thickness and the load as well as the rotating speed is discussed,and the power losses of the slipper respectively due to the variations of load and rotating speed are analyzed and compared.The results indicate that the rotating speed affects the power loss more greatly than the load because the increase in rotating speed may result in the increase of not only the shear flow loss but also the pressure difference loss.
