Flange sleeve, method for the production thereof and bending tool for producing flanges on a sleeve

Abstract

A flanged bush for plain bearings having at least one flange formed thereon having axially facing inner and outer surfaces and including at least one metallic layer. The flange includes material-displacing recesses impressed axially into said flange in said metallic layer at at least two points distributed over said flange in a circumferential direction.

1 . A flanged bush for plain bearings having at least one flange formed thereon having axially facing inner and outer surfaces and including at least one metallic layer, wherein 
 the flange includes material-displacing recesses impressed axially into said flange in said metallic layer at at least two points distributed over said flange in a circumferential direction.    
   
   
       2 . A flanged bush according to  claim 1 , wherein said recesses are located on said inner surface of said flange.  
   
   
       3 . A flanged bush according to  claim 1 , wherein said recesses are located on said outer surface of said flange.  
   
   
       4 . A flange bush according to  claim 1 , wherein said recesses are formed in said inner surface and said outer surface of said flange.  
   
   
       5 . A flanged bush according to  claim 1 , wherein said recesses extend to an outer peripheral edge of said flange.  
   
   
       6 . A flanged bush according to  claim 1 , wherein said recesses widen circumferentially in a direction radially outwardly of said bush.  
   
   
       7 . A flanged bush according to  claim 1 , wherein said recesses have a generally semicircular shape.  
   
   
       8 . A flanged bush according to  claim 1 , wherein said recesses have a wedge shape.  
   
   
       9 . A flanged bush according to  claim 1 , wherein said recesses have a width that increases axially in a direction radially outwardly of said bush.  
   
   
       10 . A flanged bush according to  claim 1 , wherein said recesses extend radially over the entire width of the flange.
