Wear assembly

Abstract

A wear assembly that includes a base and at least one wear member. The wear member can have a bit portion that has an increased dimension relative to the mounting portion and/or a mounting portion with one or more reliefs located on each side and/or bottom of the wear member. The reliefs may include a portion that extends upward near the rear of the wear member.

I/We claim: 
     
         1 . A wear member for earth working equipment comprising a body extending in a longitudinal direction and including:
 a rear mounting portion having an exterior surface and a rearward-opening mounting cavity; and   a front bit portion forward of the mounting cavity and having an exterior surface with at least one transverse dimension that is larger than at least one same transverse dimension of the exterior surface of the rear mounting portion.   
     
     
         2 . The wear member of  claim 1 , wherein the at least one transverse dimension is along a horizontal plane. 
     
     
         3 . The wear member of  claim 1 , wherein the at least one transverse dimension is along a vertical plane. 
     
     
         4 . A wear member for earth working equipment comprising:
 a rear mounting portion having an exterior surface, a rearwardly-opening mounting cavity for receiving a base, and an opening for receiving a lock to secure the wear member to a base; and   a front bit portion forward of the mounting cavity and including an exterior surface that is wider and/or deeper than at least one axially aligned portion of the exterior surface of the rear mounting portion.   
     
     
         5 . The wear member of  claim 1 , wherein the rear mounting portion includes at least one recess in the exterior surface. 
     
     
         6 . The wear member of  claim 1 , wherein the rear mounting portion includes at least one of a top and/or bottom ridge extending from the front bit portion, wherein at least a portion of the ridge has the same depth dimension as at least a portion of the front bit portion. 
     
     
         7 . The wear member of  claim 1 , wherein the front bit portion is between 45-65% of an overall length of the wear member. 
     
     
         8 . A wear member for earth working equipment comprising:
 a front bit portion;   a rear mounting portion having a rearward-opening mounting cavity, and   an exterior with one or more exterior recess rearward of the front bit portion and below a side lock-receiving opening.   
     
     
         9 . The wear member of  claim 8 , wherein exterior recess extends rearward of the side lock-receiving opening. 
     
     
         10 . The wear member of  claim 8 , wherein the one or more exterior recess extends to near a rear surface of the wear member. 
     
     
         11 . A wear member for earth working equipment comprising:
 a rear end and a front end;   a mounting cavity opening in the rear end to receive a supportive base; and   an exterior wearable surface including side surfaces, at least one of the side surfaces having a lock-receiving opening for situating a lock therein to secure the wear member to the base, and a side recess extending (i) between the lock-receiving opening and the rear end and (ii) below and forward of the lock-receiving opening.   
     
     
         12 . The wear member of  claim 11 , wherein each of the side surfaces includes one said lock-receiving opening and one said side recess. 
     
     
         13 . The wear member of  claim 12 , wherein the side recesses are separated by an axial ridge along the bottom of the wear member. 
     
     
         14 . The wear member of  claim 12 , wherein each said side recess extends into a bottom portion of the wear member. 
     
     
         15 . The wear member of  claim 11 , wherein the side recess creates a thickness by thinly outlining the base along sides and a bottom of the wear member. 
     
     
         16 . The wear member of  claim 15 , wherein the thickness changes rearwardly to become thinner. 
     
     
         17 . The wear member of  claim 12  including a bit portion forward of the mounting cavity that includes a bottom recess on a bottom of the wear member, wherein the bottom recess does not communicate with any said side recess. 
     
     
         18 . The wear member of  claim 12 , wherein the side recess on at least one side surface axially rearward of the center of the lock-receiving opening has an axial dimension that is between 10-15% of the largest axial dimension of the side recess. 
     
     
         19 . The wear member of  claim 15 , wherein the exterior recess creates a recess surface that outlines the mounting cavity.
