Rotating wheel mounting structure

Abstract

A rotating wheel mounting structure includes a rotating shaft having a flat segment, a rotating wheel mounted on the rotating shaft, a locating member mounted on the rotating shaft and stopped at one side of the rotating wheel, a locating member mounted has a through hole and a flat engaging segment that structurally matches the flat segment of the rotating shaft, and a lock member fastened to the rotating shaft to lock the locating member and the rotating wheel, and thus fixation between the locating member and the rotating shaft prohibits the lock member from being rotated in the reversed direction and loosened due to an inertia on the rotating wheel.

What is claimed is: 
     
         1 . A rotating wheel mounting structure, comprising:
 a rotating shaft comprising a threaded segment and a flat segment;   a rotating wheel mounted on said rotating shaft, said rotating wheel comprising an inner wall and an opposing outer wall;   an inner gasket mounted on said rotating shaft and attached to said inner wall of said rotating wheel;   an locating member has a through hole and a flat engaging segment that structurally matches the flat segment of the rotating shaft, said locating member is mounted around the rotating shaft and engages with the rotating shaft by means of the flat engaging segment, said locating member is such arranged that it abuts against the outer wall of the rotating wheel;   a lock member fastened to said threaded segment of said rotating shaft and stopped against said locating member.   
     
     
         2 . The rotating wheel mounting structure as claimed in  claim 1 , further comprising an outer gasket mounted on said rotating shaft and set between said outer wall of said rotating wheel and said locating member. 
     
     
         3 . The rotating wheel mounting structure as claimed in  claim 2 , wherein said locating member comprises at least one connection portion fastened to said outer gasket. 
     
     
         4 . The rotating wheel mounting structure as claimed in  claim 3 , wherein each said connection portion is a through hole, and said outer gasket comprises at least one screw hole respectively fastened to said at least one connection portion of said locating member by a respective screw to prohibit said outer gasket from a rotary motion relative to said locating member. 
     
     
         5 . The rotating wheel mounting structure as claimed in  claim 3 , wherein each said connection portion is a through hole, and said outer gasket comprises at least one pin respectively press-fitted into said at least one connection portion of said locating member to prohibit said outer gasket from a rotary motion relative to said locating member. 
     
     
         6 . The rotating wheel mounting structure as claimed in  claim 2 , wherein said locating member comprises at least one connection portion fastened to said outer gasket. 
     
     
         7 . The rotating wheel mounting structure as claimed in  claim 1 , wherein, the flat segment of the rotating shaft extends along the axis of the rotating shaft. 
     
     
         8 . The rotating wheel mounting structure as claimed in  claim 2 , wherein, the flat segment of the rotating shaft extends along the axis of the rotating shaft. 
     
     
         9 . The rotating wheel mounting structure as claimed in  claim 3 , wherein, the flat segment of the rotating shaft extends along the axis of the rotating shaft. 
     
     
         10 . The rotating wheel mounting structure as claimed in  claim 4 , wherein, the flat segment of the rotating shaft extends along the axis of the rotating shaft. 
     
     
         11 . The rotating wheel mounting structure as claimed in  claim 5 , wherein, the flat segment of the rotating shaft extends along the axis of the rotating shaft.
