摘要
斜盘-滑靴副是轴向柱塞泵的重要摩擦副之一,对柱塞泵的工作可靠性有着重要的影响。传统滑靴副油膜设计采用剩余压紧力法,并没有完整考虑油膜挤压效应对滑靴的动态支承力。针对轴向柱塞泵斜盘-滑靴副油膜的支承力受挤压效应影响进行了研究。通过控制滑靴挤压速度,利用CFD流体仿真方法,验证挤压效应的存在及结构参数和油液动力粘度对油膜挤压效应的影响。
Swashplate-slipper pairs are one of the important frictional sub of axial piston pump,which have an important influence on the working reliability of piston pump.The traditional design of the slipper pairs oil film uses the residual compression force method,and does not completely consider the dynamic support force of the oil film extrusion effect on the slipper.In this paper,the influence of squeezing effect on thrust force of swash plate-slipper pairs oil film of axial piston pump is studied.The existence of the squeeze effect and the influence of structural parameters and fluid dynamic viscosity on oil film squeeze effect are verified by controlling the squeeze speed of the slipper and using CFD fluid simulation method.
