Abstract

本发明涉及斜盘泵技术领域。该变曲面滚子副斜盘泵，其包括柱塞(1)、柱塞缸(2)、滚子(3)、止推盘(4)、导向槽(5)、斜盘(6)。柱塞轴中心向斜盘方向伸出两个滚子(3)，夹住斜盘(6)。柱塞(1)同轴活动安装在柱塞缸(2)内。斜盘(6)两端有止推盘(4)，限制斜盘(6)不进行左右位移。机体内侧轴向布置导向槽(5)，限制柱塞(1)在轴向位移时不旋转，保持斜盘(6)与滚子(3)始终处于相切状态。当斜盘(6)转动时，滚子(3)受切向力的作用，会带动柱塞(1)沿柱塞(1)轴线往复移动。柱塞(1)与柱塞缸(2)形成的闭合空腔容积随之改变，实现了泵的功能。

Description

变曲面滚子副斜盘泵
本发明涉及斜盘式柱塞泵和马达技术领域。
目前斜盘式柱塞泵，柱塞与斜盘之间靠平面连接副与平面斜盘表面滑动摩擦传动，摩擦功大，磨损大，可靠和耐久性低。如果采用滚子在变曲面斜盘表面滚动来传动，将斜盘的旋转力转化成柱塞的轴向往复力，就能解决柱塞平面连接副与斜盘表面磨擦功大的问题。
本发明的目的在于提供一种耐久性好，可靠性高的斜盘式柱塞泵。
本发明的技术方案是这样实现的，该变曲面滚子副斜盘泵，包括柱塞，柱塞缸，滚子，止推盘，导向槽，斜盘。柱塞轴中心向斜盘方向伸出两个滚子，夹住斜盘。柱塞同轴活动安装在柱塞缸内。斜盘两端有止推盘，限制斜盘不进行左右位移。机体内侧轴向布置导向槽，限制柱塞在轴向位移时不进行旋转，保持斜盘与滚子始终处于相切状态，即滚子与斜盘的切线始终与滚子轴线平行。当斜盘转动时，滚子受切向力的作用，会带动柱塞沿柱塞轴向左右移动。柱塞与柱塞缸形成的闭合空腔容积随之改变，实现了泵气功能。
该发明柱塞轴中心向斜盘方向伸出两个滚子，夹住斜盘，斜盘与滚子始终处于相切状态。
该发明斜盘(6)表面呈变曲面。
本发明的有益效果是，柱塞上的滚子和斜盘切线配合，滚动配合摩擦小，可靠性高。
附图说明：
图1、变曲面滚子副斜盘泵剖视图。
下面结合附图说明对本发明作如下详细描述。
如图1所示，该变曲面滚子副斜盘泵由柱塞1、柱塞缸2、滚子3、止推盘4、导向槽5、斜盘6组成。柱塞轴中心向斜盘方向伸出两个滚子(3)，夹住斜盘(6)。柱塞(1)同轴活动安装在柱塞缸(2)内。斜盘(6)两端有止推盘(4)，限制斜盘(6)不进行左右位移。机体内侧轴向布置导向槽(5)，限制柱塞 (1)在轴向位移时不进行旋转，保持斜盘(6)与滚子(3)始终处于相切状态，即滚子(3)与斜盘(6) 的相切线始终与滚子(3)轴线平行。当斜盘(6)转动时，滚子(3)受切向力的作用，会带动柱塞(1) 沿柱塞(1)轴向左右移动。柱塞(1)与柱塞缸(2)形成的闭合空腔容积随之改变，实现了泵气功能。
