Research On Structural Optimization And Lubrication Characteristics Of Slipper Components Of High Pressure Axial Piston Pump

In modern hydraulic transmission technology,axial piston pump is one of the most important power components.At present,the development trend of the axial piston pump is high pressure,high output flow,low noise and long service life.The axial piston pump consists of three important friction components-slipper and slanted disk.The components of the components,the plunger and the cylinder bore are composed of the components,the flow plate and the cylinder body.The friction and lubrication characteristics of these three key friction components are the main factors to form the performance of the axial piston pump.In the pump operation,the slipper can transform the spindle motion into the straight line motion of the cylinder plug,and the plunger is in the cylinder Kong Zhong.Linear motion is adopted to achieve the oil suction and oil pressure of the axial piston pump,and the distributor plate periodically completes the distribution of oil suction and oil discharge.If you want to improve the performance of the axial piston pump,it is necessary to ensure that these three large friction components have good friction and lubrication performance,and to achieve these,we should study the structure and influence factors of the three large friction components.This paper aims at a high pressure axial piston pump,one of the friction components.The development of slipper components.The main contents are as follows:In this paper,according to the structural characteristics of high pressure axial piston pump slipper,the movement rule and the force condition of the slipper are analyzed,and a mathematical model is established.Based on the principle of fluid mechanics,the damping characteristic equation of slipper is derived.Force situation of combining sliding boots components,and deduce the pressure coefficient of sliding boots components and balance coefficient equation,the mathematical model set up its pressure coefficient and the relation between the equilibrium coefficient,analyze its links with the structural parameters of sliding boots.The simulation analysis of the fluid distribution in the high pressure zone and the low pressure zone lays a foundation for the next two chapters.For sliding boots components damping hole structure study,by changing the structure of the damping hole to study their influence on the performance of the sliding boots components,puts forward the sliding boots damping hole diameter and the ratio of the length relations,given range,and use mathematical equations to describe.For researches on the underside structure sliding boots,mainly in two ways: one is to slide on the surface of the soles to study the inner and outer radius size,2 it is set in the center of the slip soles surface oil cavity in auxiliary bearing,and has the auxiliary support was deduced formula for hydraulic reverse thrust and oil leakage flow formula;The effects of the two types of sliding shoe sole structure on its performance were studied.
