通过建立柱塞副油膜的数学模型,以某型斜盘式轴向斜柱塞泵为研究对象分析了柱塞副油膜的速度和压力分布特性,得出了油膜的温度分布规律。研究了压力、转速、壁温和入口油温等单一参数对油膜温度特性的影响。结果表明:油膜温度的升高量随油液压力、柱塞泵转速增大而上升,随入口油液温度的升高而降低,油膜的温度峰值可能出现在柱塞副内部。
通過建立柱塞副油膜的數學模型,以某型斜盤式軸嚮斜柱塞泵為研究對象分析瞭柱塞副油膜的速度和壓力分佈特性,得齣瞭油膜的溫度分佈規律。研究瞭壓力、轉速、壁溫和入口油溫等單一參數對油膜溫度特性的影響。結果錶明:油膜溫度的升高量隨油液壓力、柱塞泵轉速增大而上升,隨入口油液溫度的升高而降低,油膜的溫度峰值可能齣現在柱塞副內部。

A mathematical model was built,and the flow status of film in piston pair was re-searched,based on an axial piston pump of Rexroth Company,Germany.It focused on affects to film temperature against different pressure,speed,entrance oil temperature and wall temperature and com-bined with software control variably.It shows that the film temperature is in direct ratio to the pres-sure,speed,and while in inverse ratio to entrance oil temperature and wall temperature.The peak of oil temperature maybe exists in piston pair.
