摘要： A wear assembly for use on various kinds of earth working equipment that includes a base with a supporting portion, a wear member with a cavity into which the supporting portion is received, and a lock to releasably secure the wear member to the base. The supporting portion is formed with top and bottom recesses that receive complementary projections of the wear member. These recesses and projections include aligned holes so as to receive and position the lock centrally within the wear assembly and remote from the wear surface. The hole in the wear member is defined by a wall that includes a retaining structure provided with an upper bearing surface and a lower bearing surface for contacting and retaining the lock against upward and downward movement in the hole. The lock includes a mounting component that defines a threaded opening for receiving a threaded pin that is used to releasably hold the wear member to the base. The separate mounting component can be easily manufactured and secured within the wear member for less expense and higher quality than forming the threads directly in the wear member.

摘要翻译： 一种用于各种地球工作设备的磨损组件，包括具有支撑部分的基座，具有腔体的耐磨构件，支撑部分被容纳在其中，以及用于将磨损构件可释放地固定到基座的锁。 支撑部分形成有接收磨损构件的互补突起的顶部和底部凹部。 这些凹部和突起包括对准的孔，以便将锁定件容纳并定位在磨损组件内并远离磨损表面。 磨损构件中的孔由一个壁限定，该壁包括一个保持结构，该保持结构具有上支承表面和下支承表面，用于接触和保持锁定件以防止孔中的上下运动。 该锁包括安装部件，该安装部件限定用于容纳用于可释放地将磨损部件保持在底座上的螺纹销的螺纹开口。 单独的安装部件可以容易地制造和固定在磨损部件内，以便在直接在磨损部件中形成螺纹以获得更少的成本和更高的质量。
