Description

说 明 书 一种采用十字轴关节轴承的摆筒式容积泵 技术领域
本发明涉及一种泵, 特别是一种摆筒式容积泵。
背景技术
现有的摆筒式容积泵, 包括用于与电机连接的主轴, 所述主轴 的上部倾斜设置有随主轴转动而摆动的转筒, 转筒的周围均勾布置 有三个以上的容积腔并由所述容积腔组成缸体, 转筒的外侧均勾安 装有球轴承, 所述球轴承的下部与连杆的一端连接, 连杆的另一端 为球状并与设置在容积腔内的活塞活动连接; 由于这种容积泵将主 轴的转动通过转筒的摆动而转换成容积腔内活塞的上下运动, 从而 有效满足沙漠或者高原地区对潜水电泵高扬程的需求。 但目前转筒 外侧的球轴承采用的是滑动轴承结构, 由于运动时为滑动摩擦, 摩 擦系数大, 导致传动效率不够理想, 且其磨损会缩短泵的维护周期、 影响其使用寿命。
发明内容
为了克服现有技术的不足, 本发明提供一种传动效率更高、 耐 磨损、 维护周期长的采用十字轴关节轴承的摆筒式容积泵。
本发明解决其技术问题所采用的技术方案是:
一种采用十字轴关节轴承的摆筒式容积泵, 包括容积泵壳体、 用于与电机连接的主轴, 所述主轴上部倾斜设置有随主轴转动而摆 动的转筒, 转筒周围均勾布置有三个以上的销轴, 所述销轴上套装 有十字轴关节轴承,所述十字轴关节轴承包括穿装在销轴上的轴承, 轴承外圈固定连接有摆套, 所述摆套的左右两侧分别延伸有同一轴 线并与销轴形成十字的固定轴, 固定轴上分别穿装有左、 右轴承, 左、 右轴承的外圈分别固定连接有左、 右十字轴摆套, 所述左、 右 十字轴摆套的顶端相互固定连接, 左、 右十字轴摆套的底端固定连 接有与容积腔内的活塞铰接的连杆。
作为上述技术方案的进一步改进:所述主轴的上部连接有下 斜轴, 下斜轴通过倾斜的螺杆连接有上斜轴, 所述上、 下斜轴上分 别安装有由至少一个轴承组成的轴承组, 所述转筒套装在该轴承组 的外侧。
作为对上述技术方案的再进一步改进: 前述的左、右十字轴摆 套的顶端通过连接板连接固定。 所述的容积泵壳体上设有对应摆套 的限位挡板, 摆套的从动端安装有与限位挡板相配合的滚轮。 滚轮 为锥型滚轮, 或者滚轮为腰鼓型滚轮。
作为对上述技术方案的更进一步改进: 前述的轴承以及左、右轴 承分别为单个滚动轴承结构或由多个滚动轴承组成的组件。
本发明的有益效果是: 本产品主要是采用摆套和位于摆套左右 两侧而且处于同一轴线上左、右十字轴摆套来替代原来的轴承结构, 由于摆套和左、 右十字轴摆套上采用的是滚动轴承, 较之原来球轴 承所采用的滑动摩擦结构具有磨损小、 功耗少、转动灵敏、转速高、 使用寿命长的特点, 从而更加符合底碳经济中对容积泵能效高、 延 成维护周期的要求。
附图说明
下面结合附图和实施例对本发明进一步说明。
图 1是本发明的结构示意图;
图 2是本发明的十字轴关节轴承结构拆分图。
具体实施方式
参照图 1、 图 2, 一种采用十字轴关节轴承的摆筒式容积泵, 包括容积泵壳体、用于与电机连接的主轴 1,所述主轴 1的上部倾斜 设置有随主轴 1转动而摆动的转筒 2,转筒 2的周围均勾布置有三个 以上的销轴 3, 所述销轴 3上套装有十字轴关节轴承 4, 所述的十字 轴关节轴承 4包括穿装在销轴 3上的轴承 41,轴承 41的外圈固定连 接有摆套 42,所述摆套 42的左右两侧分别延伸有同一轴线并与销轴 3形成十字的固定轴 421、 421 ' , 当然实际中也可以采用上下设计 的形式, 固定轴 421、 421, 上分别穿装有左、 右轴承 43、 43,, 左、 右轴承 43、 43 ' 的外圈分别固定连接有左、右十字轴摆套 44, 44', 左、右十字轴摆套 44, 44' 的顶端通过连接板 45连接固定, 当然也 可以将其直接连接固定,左、右十字轴摆套 44, 44' 的底端固定连接 有与容积腔内的活塞铰接的连杆 5。
本发明为了实现转筒 2能随主轴 1转动而摆动, 所述主轴 1的 上部连接有下斜轴 6, 下斜轴 6通过倾斜的螺杆连接有上斜轴 7, 所 述上、下斜轴 6、 7上分别安装有由至少一个轴承组成的轴承组, 所 述转筒 2套装在该轴承组的外侧, 另外, 容积泵壳体上设有对应摆 套 42的限位挡板 9,摆套 42的从动端安装有与限位挡板 9相配合的 滚轮 8, 滚轮 8受到限位挡板 9阻挡, 不会跟随上、 下斜轴 6、 7转 动, 而只会摆动, 因此可以通过连杆 5带动容积腔内的活塞上下运 动, 进行液体输送。 当然滚轮的安装方式并不限于本实施例所采用 的方式, 也可以是: 在转筒 2的周围均勾设置与销轴 3数量对应的 滚轮固定轴, 滚轮固定轴上安装与限位挡板 9相配合的滚轮 8。
为了保证滚轮 8的转动更为顺畅, 滚轮 8可以是锥型滚轮, 锥 型滚轮有效保证转动的角速度保持一致, 另外, 滚轮 8也可以是腰 鼓型滚轮, 腰鼓型滚轮可以减少与限位挡板 9的接触面积, 而且避 免滚轮 8转动时的内外速度的差异。
本产品为了保证摆套 42以及左、 右十字轴摆套 44, 44' 的转动 更为灵敏, 所述的轴承 41以及左、右轴承 43、 43'分别为单个滚动 轴承结构或由多个滚动轴承组成的组件。
本产品主要是采用摆套 42和位于摆套 42左右两侧而且处以同 一轴线上左、 右十字轴摆套 44, 44' 来替代原来的球轴承结构, 由 于摆套和左、 右十字轴摆套上采用的是滚动轴承, 较之原来球轴承 所采用的滑动摩擦结构具有磨损小、 功耗少、 转动灵敏、 转速高、 使用寿命长的特点, 从而更加符合底碳经济中对容积泵能效高、 延 成维护周期的要求。
