Abstract

本实用新型公开了一种外啮合渐开线齿轮机油泵,包括泵体和泵盖,所述泵体上设有进油孔、出油孔和轴孔,所述泵盖上设有进口油槽、出口油槽和轴孔;在泵体进油孔的两边各设有一条弧形的缓蚀槽,与此相应,在泵盖进口油槽的两边同样各设有一条弧形的缓蚀槽。上述技术方案中,通过增加缓蚀槽后油泵在相同转速和出口压力的情况下齿轮气蚀问题可明显得到解决,在相同转速下(特指高速)油泵的容积效率有明显提升,油泵的使用寿命延长,并且能够减小高速高压时油泵出口的压力波动和噪音。

Description

一种外啮合渐开线齿轮机油泵
技术领域
本实用新型涉及一种机油泵,具体涉及一种外啮合渐开线齿轮机油泵。
背景技术
传统的外啮合渐开线齿轮机油泵在高速运转时进口油液填充时间短,出现进口负压低于油液的气液分离压力导致齿槽出现低压气体,当齿轮运转到高压区使气体又迅速溶解于液体由于体积突变油液会对齿面和泵腔壁面产生强烈冲击导致油泵产生气蚀。
实用新型内容
本实用新型要解决的技术问题是提供一种可以防止气蚀的外啮合渐开线齿轮机油泵。
为解决上述技术问题,本实用新型的技术方案是:一种外啮合渐开线齿轮机油泵,包括泵体和泵盖,所述泵体上设有进油孔、出油孔和轴孔,所述泵盖上设有进口油槽、出口油槽和轴孔;在泵体进油孔的两边各设有一条弧形的缓蚀槽,与此相应,在泵盖进口油槽的两边同样各设有一条弧形的缓蚀槽。
上述技术方案中,通过增加缓蚀槽后油泵在相同转速和出口压力的情况下齿轮气蚀问题可明显得到解决,在相同转速下(特指高速)油泵的容积效率有明显提升,油泵的使用寿命延长,并且能够减小高速高压时油泵出口的压力波动和噪音。
附图说明
图1为本实用新型的泵体结构示意图;
图2为本实用新型的泵盖结构示意图。
具体实施方式
如图1、2所示,本实用新型的优选实施例是:一种外啮合渐开线齿轮机油泵,包括泵体和泵盖,所述泵体上设有进油孔3、出油孔4和两个轴孔2,所述泵盖上设有进口油槽6、出口油槽8和轴孔7;在泵体进油孔3的两边各设有一条弧形的缓蚀槽1,与此相应,在泵盖进口油槽6的两边同样各设有一条弧形的缓蚀槽5。
