摘要： An assembly is disclosed including a holder block, a cutting pick, and an optional hollow sleeve, wherein the shank of the cutting pick is inserted into the holder block or, where present, into the hollow sleeve. When assembled, surfaces of the components meet at an interface. At least one of the first interface and the second interface includes one or more sets of wear elements including cemented carbide bodies press fit into recesses in the forwardly oriented surfaces meeting at the interfaces. The wear elements mitigate direct contact between the opposing surfaces of the components at the interfaces and prevents excessive wear from repetitive impact because the harder wear elements, e.g., cemented carbide, are contact points between the opposing surfaces of the components at the interfaces. A machine incorporating the assembly and a method of manufacturing the assembly are also disclosed, particularly a machine for mining, excavating, tunneling, road planing and/or construction.
摘要翻译： 公开了一种组件，其包括保持器块，切割拾取器和可选的中空套管，其中切割拾取器的柄部插入保持器块中，或者在存在的状态下插入中空套筒中。 组装时，部件表面在界面处相遇。 第一界面和第二界面中的至少一个包括一组或多组磨损元件，包括硬化碳体体压配合到在界面处相交的向前定向表面中的凹槽中。 磨损元件减轻了界面处的部件的相对表面之间的直接接触，并且防止了重复冲击的过度磨损，因为较硬的磨损元件（例如硬质合金）是在界面处的部件的相对表面之间的接触点。 还公开了一种包括组件的机器和制造组件的方法，特别是用于采矿，挖掘，隧道掘进，道路平整和/或施工的机器。
