Abstract

一种轴中轴定心滑板转子泵，由壳体、转子（4）、曲轴（8）、滑板（5）、叶片（6）构成，由于曲柄（8）的限制，滑板（5）在随转子（4）转动时会避免惯性作用与壳体的摩擦，使泵流量大、体积小、效率高并且用途广，适用于油泵、水泵、马达、真空泵、驱动浆等。

Description

轴中轴定心滑板转子泵
技术领域；本发明涉及一种泵，是叶片泵的改进结构。它能用于油泵、水泵、马达、空压机、真空泵、驱动桨等。
背景技术：近一个世纪以来，有一种叶片泵，常用于液压传动，它由壳体、转子、叶片等构成，由于叶片在转子上是辐射状安装，致使叶片的厚度和伸长都受到限制，因为惯性力的作用，叶片是随厚度的增加而与壳体的摩擦力加大，噪声相应剧增，使用寿命缩短。叶片伸出长度受到转子槽深的限制，所以叶片泵的容积空间都很小，则流量小、体积大、效率低，因此目前为止它仅限于以传动为目的液压泵中使用，其它以流量为目用泵的场合就极为少见。
发明内容：对于现有技术存在的上述缺陷，本发明旨在提供一种流量大、体积小、效率高、噪声低的轴中轴定心滑板转子泵。
为了达到上述目的，本发明采用了以下技术方案：它包括转子内有一个曲轴，至少一个或多个滑板交叉装在曲轴上并对穿在转子的槽内，滑板能在槽内滑动，曲轴通过定心套的作用限制了滑板在槽上的滑动范围，曲轴的一端由转子内的轴承支撑，另一端由夹板上的轴承支撑，尾轴装在转子上，连同曲轴一起装在壳体内由前盖和后盖上的轴承支撑，曲轴的一端固定在后盖上，不允许转动，转子和滑板一起转动时，滑板顶端始终保持与壳体有一点间隙。
每个滑板分两段固定在梭环上组成一个整体，滑板的顶端装有叶片，滑板随转子转动时，通过曲轴上的定心套限制了滑板在转子上的伸出长度，使转子与滑板分别围绕在两个圆心上旋转。
转子上的内螺纹与夹板上的外螺纹配合装在一起，转子上的外螺纹与尾轴上的内螺纹配合装在一起，夹紧螺丝穿过尾轴与夹板的内螺纹配合装在一起，把转子与尾轴固定成一个整体。
同现有技术相比：本发明因为采用了上述方案，将叶片在转子上的辐射状安装改为滑板对穿在转子上，滑板的伸出长度大大延长，采用曲轴定心的方法具有多种作用：一、滑板与壳体能够保持一定间隙，避免了滑板与壳体的摩擦力及磨损；二、避免了因滑板的加厚使惯性力增加而引起滑板与壳体的撞击加剧，因此滑板能够任意加厚加长；三、转子和滑板在高转速时噪声和振动大大降低，转速能够成倍增加，伴随功效也能成倍提高，这就为它使用范围的扩展提供了先决条件，比如高速马达、船舰驱动桨等；四、在允许滑板进一步加厚加 长的情况下，则能得到压力高、流量大、体积小、效率高。

具体实施方式：下面结合附图的具体实施对本发明作进一步说明；
实施例1
如图1、图2中所示，转子4内有一个曲轴8，至少一个或多个滑板5交叉装在曲轴8上并对穿在转子的槽内，滑板5能在槽内滑动，曲轴8通过定心套11的作用限制了滑板5在槽上的滑动范围，曲轴8的一端由转子4内的轴承9支撑，另一端由夹板3上的轴承9支撑，尾轴2装在转子4上，连同曲轴8一起装在壳体12内由前盖10和后盖1上的轴承9支撑，曲轴8的一端固定在后盖1上，不允许转动，转子4和滑板5一起转动时，滑板5顶端始终保持与壳体4有一点间隙。
每个滑板5分两段固定在梭环7上组成一个整体，滑板5的顶端装有叶片6，滑板5随转子4转动时，通过曲轴8上的定心套11限制了滑板5在转子上的伸出长度，使转子4与滑板5分别围绕在两个圆心上旋转。
转子4上的内螺纹与夹板3上的外螺纹配合装在一起，转子4上的外螺纹与尾轴2上的内螺纹配合装在一起，夹紧螺丝13穿过尾轴2与夹板3的内螺纹配合装在一起，把转子4与尾轴2固定成一个整体。
