Abstract

Background

Axial piston pumps represent one of the most core and technically challenging components in hydraulic systems. They are widely used in practical engineering fields such as hydraulic transmission and control. This article first outlines the development history of piston pumps and then provides a comprehensive analysis of the research progress on the friction characteristics and surface modification technologies of key friction pairs in axial piston pumps.

Objective

This article aims to summarize the friction wear and oil film characteristics of key friction pairs in axial piston pumps, analyze and elaborate the research progress in improving the tribological performance of friction pair surfaces through methods such as surface texturing and surface coating, and provide theoretical support for the damage and protection of axial piston pumps.

Method

The present study was conducted by organizing and analyzing research literature from both domestic and international scholars. The objective was to explore the lubrication and friction wear properties of key friction pairs, as well as the application of surface texturing, surface coating, and other technologies in improving the tribological performance of friction pair surfaces.

Results

A review of pertinent literature has revealed that surface texturing and surface coating can effectively reduce the friction coefficient of friction pairs, enhance lubrication performance, and thereby extend the service life of axial piston pumps. Moreover, these methods facilitate the reduction of wear on the friction pairs and enhance their overall performance.

Conclusion

This article presents a summary of the research progress on friction, wear, and oil film characteristics of key friction pairs in axial piston pumps. It also analyzes the role of technologies such as surface texturing and surface coating in improving the tribological properties of the friction pair surfaces. Furthermore, it provides a prospective outlook on future developments.
