Description

一种泵轴
技术领域
本实用新型涉及泵类，尤其是一种泵轴。
背景技术
现有离心泵的泵轴与冲压叶轮、模压叶轮或注塑叶轮的联接方式主要有花键轴联接、平键联接、多边形轴联接等几种。花键轴加工复杂、加工成本高、检验困难、精度难以保证，大批量加工效率比较低；平键联接对轴的强度削弱较大，键槽加工困难，而且影响动平衡；多边形轴加工量大，对轴的强度削弱较大。
实用新型内容
本实用新型要解决上述现有技术的缺点，提供一种泵轴，解决泵轴与叶轮联接部分加工复杂、加工成本高、精度低、影响轴强度、装配精度差、整机性能难以保证的问题。
本实用新型解决其技术问题采用的技术方案：这种泵轴，泵轴的中间设有与叶轮轴孔配合的扁轴，扁轴的一端为螺纹端，扁轴的另一端设有轴肩。
作为优选，所述扁轴的上、下两个面与轴中心面对称。
与现有技术相比本实用新型的优点是：加工方便，精度容易保证，测量简单，对强度削弱小，动平衡，装配方便，能满足使用要求，整机性能稳定。对应配套的叶轮轴孔也为扁轴孔结构，采用冲压、模压、注塑等工艺一次性成形，效率非常高。
附图说明
图1是本实用新型的主视结构示意图。
图2是本实用新型图1的A-A剖视图。
图3是本实用新型的泵轴与冲压叶轮的安装示意图。
图4是本实用新型中与泵轴配套的叶轮后盖板的结构示意图。
图中：1-螺纹端，2-扁轴，3-轴肩，4-螺母，5-垫圈，6-冲压叶轮，6-1-叶轮轴孔。
具体实施方式
下面结合附图和实施例对本实用新型作进一步说明：
如图所示，这种泵轴，在泵轴的中间设有与叶轮轴孔6-1配合的扁轴2，扁轴2的一端为螺纹端1，扁轴2的另一端设有轴肩3，所述扁轴2的上、下两个面与轴中心面对称。
工作原理：泵轴叶轮联接部分采用对称的扁轴2结构，配合的叶轮轴孔6-1也采用扁轴孔，轴的圆面部分用于叶轮的轴心定位，轴的上、下两个扁面用于传递扭矩。
如图4所示，冲压叶轮6上设有叶轮轴孔6-1，叶轮轴孔6-1冲压成和扁轴2配套的扁轴孔，图3是一种扁轴孔冲压叶轮6与泵轴的安装形式，依次装入冲压叶轮6，垫圈5和螺母4压紧。
除上述实施例外，本实用新型还可以有其他实施方式。凡采用等同替换或等效变换形成的技术方案，均落在本实用新型要求的保护范围。
