Wear assembly for use on earth working equipment

Abstract

A wear assembly for excavating equipment which includes a wear member and a base each with upper and lower stabilizing surfaces that are offset and at overlapping depths to reduce the overall depth of the assembly while maintaining high strength and a stable coupling. The nose and socket each includes a generally triangular-shaped front stabilizing end to provide a highly stable front connection between the nose and wear member for both vertical and side loading. The lock is movable between hold and release positions to accommodate replacing of the wear member when needed, and secured to the wear member for shipping and storage purposes.

         42 . A wear assembly for excavating equipment comprising:
 a wear member having a cavity to receive a base on the excavating equipment, and a hole extending through the wear member to the cavity; and   a lock received in the hole and adjustable between a hold position where the lock interacts with the base to hold the wear member on the base when the base is in the cavity, and a release position where the lock permits installation of the wear member on the base, the lock including a tool-receiving formation to receive a tool to adjust the lock between the hold and release positions without the use of threads and without a hammer, the lock being secured to the wear member in both the hold position and the release position irrespective of the insertion of the base into the cavity or the orientation of the wear member to form a single integral component with less risk the lock will be separated from the wear member and lost.   
     
     
         43 . A wear assembly in accordance with  claim 42  wherein the lock includes a body to interact with the base in the hold position and hold the wear member on the base when the base is in the cavity and to permit installation of the wear member on the base in the release position. 
     
     
         44 . A wear assembly in accordance with  claim 43  wherein the lock includes a resilient member to resist adjustment of the body between the hold and release positions. 
     
     
         45 . A wear assembly in accordance with  claim 44  wherein the body moves about an axis between the hold and release positions. 
     
     
         46 . A wear assembly in accordance with  claim 45  wherein the axis extends generally in the same direction the base is received into the cavity. 
     
     
         47 . A wear assembly in accordance with  claim 45  wherein the body moves less than a full turn in moving between the hold and release positions. 
     
     
         48 . A wear assembly in accordance with  claim 45  wherein the lock includes a latch operable to retain the body in each of the hold and release positions with both said positions being at pre-established locations. 
     
     
         49 . A wear assembly in accordance with  claim 42  wherein the lock includes a resilient member to resist adjustment between the hold and release positions. 
     
     
         50 . A wear assembly in accordance with  claim 49  wherein lock turns about an axis between the hold and release positions. 
     
     
         51 . A wear assembly in accordance with  claim 49  wherein the axis extends generally in the same direction the base is received into the cavity. 
     
     
         52 . A wear assembly in accordance with  claim 49  wherein the body moves less than a full turn in moving between the hold and release positions. 
     
     
         53 . A wear assembly in accordance with  claim 49  wherein the lock includes a latch operable to retain the body in each of the hold and release positions with both said positions being at pre-established locations. 
     
     
         54 . A wear assembly in accordance with  claim 42  wherein the lock turns about an axis between the hold and release positions. 
     
     
         55 . A wear assembly in accordance with  claim 54  wherein the axis extends generally in the same direction the base is received into the cavity. 
     
     
         56 . A wear assembly in accordance with  claim 54  wherein the body moves less than a full turn in moving between the hold and release positions. 
     
     
         57 . A wear assembly in accordance with  claim 54  wherein the lock includes a latch operable to retain the body in each of the hold and release positions with both said positions being at pre-established locations. 
     
     
         58 . A wear assembly in accordance with  claim 42  wherein the lock includes a latch operable to retain the body in each of the hold and release positions with both said positions being at pre-established locations. 
     
     
         59 . A wear assembly in accordance with  claim 42  wherein the lock is secured to the wear member for shipping and storage as a single integral component. 
     
     
         60 . A wear assembly in accordance with  claim 42  wherein the lock is secured to the wear member such that they are maintained as a single integral component through shipping, storage, installation and use. 
     
     
         61 . A wear assembly in accordance with  claim 42  wherein the wear member is a point with a front digging edge. 
     
     
         62 . A wear assembly in accordance with  claim 42  wherein the lock includes a body, a resilient member and a latch, the body interacts with the base in the hold position to hold the wear member on the base when the base is in the cavity, permits installation of the wear member on the base in the release position, and moves about an axis less than a full turn between the hold and release positions, the resilient member resists movement of the body between the hold and release positions, and the latch is operable to retain the body in each of the hold and release positions with both said positions being at pre-established locations.
