Abstract

两件式套环(10)经由两个肩螺栓(14)被刚性地夹持到液压驱动器轴(12)上。套环半部(16)接合在卷轴(20)上的紧公差的槽特征(18)，卷轴(20)被装配到线性传感器轴(22)上。卷轴(20)容纳磁铁(24)，该磁铁(24)将位置信号发送到传感器(26)。当在运行期间液压驱动器轴(12)往复运动时，卷轴(20)随着液压驱动器轴(12)移动，从而将位置信号传递到传感器(26)，传感器(26)告诉驱动器(28)改变方向。液压驱动器和化学泵轴(12)能随着时间缓慢旋转，这对于增加化学泵/液压驱动器的密封件寿命是优选的。

Description

泵线路线性位置传感组件
技术领域
本申请要求2009年11月4日提交的美国申请系列No.61/257,903的权益，其内容通过参考在此并入。
发明内容
线性位置传感组件将泵线路液压驱动器联接到磁性卷轴，该卷轴在允许液压和化学泵轴旋转的同时读取传感器上的位置。
在图1和2中，两件式套环(1)经由两个肩螺栓(3)刚性地夹持到液压驱动器轴(2)上。套环半部接合卷轴(4)上的紧公差的槽特征，该卷轴被装配到线性传感器轴(5)上。该卷轴容纳磁铁(6)，该磁铁将位置信号发送到传感器。当在运行期间液压驱动器轴往复运动时，卷轴随着液压驱动器轴移动，从而将位置信号传递到传感器，该传感器告诉驱动器改变方向。
存在该结构的许多优点：部件数量最小化并且设计简单。该液压驱动器和化学泵轴能够随着时间缓慢旋转，这优选地增加化学泵/液压驱动器密封件寿命。先前的线性传感组件概念具有额外的组件/特征，额外的组件/特征限制轴旋转成功运行。由于套环/卷轴联接几何形状，本发明在保持精确位置传感的同时允许完全的360度旋转。
本发明的这些和其他目的和优点将在下面结合附图给出的描述中更充分地展现，在多个附图中相同的附图标记指示相同或类似的部件。
附图说明
图1示出本发明的位置传感组件的横截面。
图2示出显示被夹持到泵轴的套环的局部横截面。
具体实施方式
在图1和2中，两件式套环10经由两个肩螺栓14刚性地夹持到液压驱动器轴12上。套环半部16接合在卷轴20上的紧公差的槽特征18，卷轴20被装配到线性传感器轴22上。卷轴20容纳磁铁24，该磁铁24将位置信号发送到传感器26。当在运行期间液压驱动器轴12往复运动时，该卷轴20随着液压驱动器轴12移动，从而将位置信号发送到传感器26，该传感器26告诉驱动器28改变方向。该液压驱动器和化学泵轴12能随着时间缓慢旋转，这对于增加化学泵/液压驱动器的密封件寿命是优选的。
可以预期的是，在不偏离由所附权利要求限定的本发明的精神和范围的情况下，可以对位置传感组件做出许多改变和变型。
