摘要： A slide hammer tool is particularly useful for replacing worn teeth of a trenching machine. The teeth are retained in chain links of the trenching machine by respective open keeper rings. The tool has a rod with stops proximate both ends. A hammer is slidable on the rod between the stops. On one rod end is a wedge with converging surfaces that match radial surfaces on the keeper rings. The other end of the rod has a concave surface that matches the keeper ring outer diameter. To remove the keeper ring from a worn tooth, the wedge converging surfaces are abutted against the keeper ring radial surfaces. The hammer is rapidly struck against the corresponding stop. The impact of the hammer on the stop is transmitted to the wedge converging surfaces and to the keeper ring radial surfaces. The impact is sufficient to cause the keeper ring opening to expand, and the keeper ring is pushed off the tooth. After a new tooth is inserted into the chain link, the rod concave surface is abutted against the keeper ring outer diameter. The hammer is rapidly struck against the second stop. The impact produced is transmitted to the rod concave surface and to the keeper ring to seat the keeper ring on the new tooth.

摘要翻译： 滑动锤工具特别适用于更换挖沟机磨损的牙齿。 齿通过相应的开放式保持环保持在挖沟机的链节中。 该工具具有靠近两端的止动杆。 锤子可以在杆之间滑动。 在一个杆端是具有与保持环上的径向表面匹配的会聚表面的楔形物。 杆的另一端具有与保持环外径相匹配的凹面。 为了从磨损的牙齿上取下保持环，楔块会聚表面抵靠保持环的径向表面。 锤子迅速撞到相应的挡块上。 锤子对止动件的冲击传递到楔形会聚表面和保持环环径向表面。 冲击力足以使保持环开口膨胀，保持环从牙齿上推出。 在将新的齿插入链节之后，杆的凹面与保持环的外径抵接。 锤子迅速击中了第二站。 所产生的冲击力传递到杆凹面和保持环，以将保持环安置在新牙上。
