摘要/Abstract

摘要： 柱塞马达配流副摩擦润滑特性对其工作性能和稳定性具有重要影响。本研究考虑带表面纹理的辅助支撑带的油膜压力分布与力矩作用，建立了配流副油膜动力学模型，分析在不同工作压力、工作转速和斜盘倾角下配流副流量泄漏以及摩擦损耗的变化规律。结果表明: 柱塞马达配流副泄漏流量随转速增加呈近线性增长，且增长速率随压力升高而下降; 而油膜粘性摩擦转矩随转速、压力增加而增大，且随转速增加呈近线性增长; 泄漏流量和中心膜厚随斜盘倾角增大均呈现下降趋势，而摩擦转矩随倾角增大而增大。

关键词: 轴向柱塞马达, 配流副, 泄漏流量, 摩擦转矩

Abstract: The working performance and stability of the axial piston motor are significantly affected by the frictional lubrication characteristics of the valve-plate pair． Considering the oil film pressure distribution and moment action of the auxiliary support belt with surface veins，this study established the oil film dynamic model of the valve-plate pair，and analyzed the change rules of the flow leakage and friction loss of the valve-plate pair under different working pressure，working speed and swash plate angle． The research results show that the leakage flow of the valveplate pair of the axial piston motor increases approximately linearly with the increase of speed，and the increase rate decreases with the increase of pressure． At the same time，the viscous-friction torque of oil film increases with the increase of the rotational speed and pressure，and there is an approximate linear relationship between the friction torque and the rotating speed． The leakage flow and the thickness of the central film decrease with the increase of the inclined angle of the swash plate，while the friction torque increases with the increase of the inclined angle．

Key words: axial piston motor, valve-plate pair, leakage flow, friction torque
