Crawler track

Abstract

A shoe for a crawler track includes a first end, a second end, a longitudinal axis extending between the first and second ends, a roller path axis extending perpendicular to the longitudinal axis, and an intermediate portion disposed between the first and second ends. The intermediate portion includes a roller-engaging portion disposed along the roller path axis, the intermediate portion including four successive faces that form a parallelogram when viewed from a direction substantially perpendicular to the longitudinal axis, two of the four faces being disposed at an acute angle relative to the longitudinal axis.

1 . A shoe for a crawler track, the shoe comprising:
 a first end;   a second end;   a longitudinal axis extending between the first and second ends;   a roller path axis extending perpendicular to the longitudinal axis;   an intermediate portion integrally formed via casting with the first and second ends and disposed between the first and second ends, the intermediate portion including a roller-engaging portion disposed along the roller path axis, the intermediate portion including at least one face disposed at an acute angle relative to the longitudinal axis.   
     
     
         2 . The shoe of  claim 1 , wherein the shoe includes four successive faces that form a parallelogram when viewed from a direction perpendicular to the longitudinal axis. 
     
     
         3 . The shoe of  claim 1 , wherein the shoe includes two faces disposed at an acute angle relative to the longitudinal axis. 
     
     
         4 . The shoe of  claim 1 , wherein acute angle is between approximately 15 degrees and 45 degrees. 
     
     
         5 . The shoe of  claim 4 , wherein the acute angle is 20 degrees. 
     
     
         6 . The shoe of  claim 4 , wherein the acute angle is 35 degrees. 
     
     
         7 . The shoe of  claim 1 , wherein each of the first and second ends includes a male member and female member, each of the male and female members including a hole to receive a pin. 
     
     
         8 . The shoe of  claim 1 , wherein the intermediate portion transitions into the first end via a curved fillet. 
     
     
         9 . The shoe of  claim 1 , further comprising alignment guides on opposite sides of the intermediate portion to align rollers relative to the shoe. 
     
     
         10 . The shoe of  claim 1 , further comprising a plurality of peening pads arranged in a pattern on the intermediate portion. 
     
     
         11 . A shoe for a crawler track, the shoe comprising:
 a first end;   a second end;   a longitudinal axis extending between the first and second ends;   a roller path axis extending perpendicular to the longitudinal axis;   an intermediate portion disposed between the first and second ends, the intermediate portion including a roller-engaging portion disposed along the roller path axis, the intermediate portion including at least one face disposed at an acute angle relative to the longitudinal axis, wherein the acute angle is between approximately 15 degrees and 45 degrees.   
     
     
         12 . The shoe of  claim 11 , wherein the shoe includes four successive faces that form a parallelogram when viewed from a direction perpendicular to the longitudinal axis. 
     
     
         13 . The shoe of  claim 11 , wherein the shoe includes two faces disposed at an acute angle relative to the longitudinal axis. 
     
     
         14 . The shoe of  claim 11 , wherein the acute angle is 20 degrees. 
     
     
         15 . The shoe of  claim 11 , wherein the acute angle is 35 degrees. 
     
     
         16 . The shoe of  claim 11 , wherein each of the first and second ends includes a male member and female member, each of the male and female members including a hole to receive a pin. 
     
     
         17 . The shoe of  claim 11 , wherein the intermediate portion transitions into the first end via a curved fillet. 
     
     
         18 . The shoe of  claim 11 , further comprising alignment guides on opposite sides of the intermediate portion to align rollers relative to the shoe.
