Abstract:
1. A wear assembly for excavating equipment, the wear assembly comprising: a support structure secured to the excavating equipment; a wear member mounted to the support structure, the wear member being positioned so as to contact material to be excavated by the excavating equipment during use such that the wear member is subjected to abrasive wear during use of the excavating equipment and protects the excavating equipment, the support structure and the wear member cooperatively defining an opening; and a wedge removably received into the opening to releasably secure the wear member to the support structure, the wedge having a leading end which is inserted first when the wedge is received into the opening, a trailing end, a length extending between the leading and trailing ends, an exterior surface tapering toward the leading end such that the leading end is narrower in width than the trailing end, and a helical groove that extends axially along the exterior surface of the wedge about the longitudinal axis, the helical groove being threadedly coupled to a thread formation in the opening such that rotation of the wedge in one direction translates the wedge farther into the opening to tighten the wedge in the opening and securely hold the wear member to the excavating equipment, and such that rotation of the wedge in an opposite direction translates the wedge out of the opening for removal of the wedge.
