摘要
分析了影响外啮合直齿轮机油泵容积效率的主要因素 ,对油泵齿谷产生空穴和间隙漏损的机理进行了探讨。从采用端面补充进油、取消卸荷槽及选择合适的进出油管通径等方面论述了提高齿轮泵容积效率的有效措施 ,并运用实例加以验证。
In this paper, main factors affecting the volumetric efficiency of external gearing cylindrical gear pump are analyzed, mechanism of hole produced in tooth space of pump and mechanism of leak loss by clearance are discussed. From respects of using supplementary oil intake from end face, removing unload groove and choosing proper flow diameters of intake and output oil pipes etc., the efficient measures of increase in volumetric efficiency of the gear pump are discussed and well proved by the case study.
