摘要：
A reciprocating pump has a driven crankshaft and a connecting rod having an aft end rotatably mounted to the crankshaft. The pump has a stationarily mounted crosshead case in which a crosshead assembly strokes. The crosshead assembly has first and second crosshead members. A retainer pivotally joins the forward end of the connecting rod to the first crosshead member. The second crosshead member has a partially cylindrical recess containing a bushing. The forward end of the connecting rod is in pivotal engagement with the bushing. The second crosshead member is releasably secured to the first crosshead member to allow removal of the second crosshead member and the bushing from the crosshead case without detaching the forward end of the connecting rod from the first crosshead member.
摘要（中）：
往复泵具有从动曲轴和具有可旋转地安装在曲轴上的后端的连杆。 泵具有固定的十字头箱体，十字头组件在其中行进。 十字头组件具有第一和第二十字头构件。 保持器将连杆的前端枢转地连接到第一十字头构件。 第二十字头构件具有包含衬套的部分圆柱形凹部。 连杆的前端与套管枢转接合。 第二十字头构件可释放地固定到第一十字头构件，以允许从十字头壳体移除第二十字头构件和衬套，而不将连杆的前端从第一十字头构件分离。
