Wear assembly

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 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.

主权项

1. A wear member for attachment to earth working equipment to protect the equipment from wear during use, the wear member comprising a front end to contact the ground during operation of the earth working equipment, a rearwardly-opening cavity with a longitudinal axis to receive a base on the earth working equipment, the cavity including a central section along the longitudinal axis and a side section to each side of the central section, each said side section including an outer side and an inner side, the inner sides each connecting with the central section, each outer side having an inwardly-projecting lateral projection defined by an upper outer bearing surface and a lower outer bearing surface, the upper and lower outer bearing surfaces being laterally inclined toward each other in an inward direction and axially extending substantially parallel to the longitudinal axis, each inner side having an inside bearing surface above and below the central section, each inside bearing surface being laterally inclined inward and away from the outer side and axially extending substantially parallel to the longitudinal axis, the outer bearing surfaces and the inside bearing surfaces each bearing against complementary bearing surfaces on the base to resist vertical and side loads applied to the wear member during use, the central section including an upper surface and a lower surface, the upper surface extending between and connecting the upper inside bearing surfaces, the lower surface extending between and connecting the lower inside bearing surfaces, the upper and lower surfaces being spaced apart to define a gap therebetween, the gap having a height between the upper and lower surfaces that is less than two-thirds of the overall height of the cavity, and at least one of the upper and lower surfaces including a hole for receiving a lock to secure the wear member to the earth working equipment.
