Guide roller for wires

Abstract

A guide roller for wires, comprising a coating support ( 1 ) in the form of a hollow cylinder which is slidable parallel to the longitudinal direction, on which a coating ( 4 ) is fixed permanently by adhesion, and having guide grooves for the wires, and which is supported on a hub part by a stabilising support ( 2 ) made from CFP or metal, wherein the coating support ( 1 ) is made of CFP and is secured on the stabilising support ( 2 ) only by a cylindrical or conical press-fitting, avoiding the use of a screw connection

1 . A guide roller for wires, comprising:
 a coating support in the form of a hollow cylinder which is slidable parallel to the longitudinal direction, on which a coating is fixed permanently by adhesion, and having guide grooves for the wires, and which is supported on a hub part by a stabilising support made from CFP or metal, wherein the coating support is made of CFP and is secured on the stabilising support only by one of a cylindrical and conical press-fitting, avoiding the use of a screw connection.   
     
     
         2 . The guide roller for wires as recited in  claim 1 , wherein the coating support and the stabilising support consist of fibre strands stuck together with synthetic resin, which are arranged in multiple plies one on top of the other and are aligned at an angle of +/−30 to 60° relative to the longitudinal axis of the hollow cylinder, wherein the successive fibre strands in the radial direction intersect each other in the opposite direction. 
     
     
         3 . The guide roller for wires as recited in  claim 1 , wherein the coating support and the stabilising support consist of fibre strands stuck together with synthetic resin, which are arranged in multiple plies one on top of the other and are aligned at an angle of +/−40 to 50° relative to the longitudinal axis of the hollow cylinder, wherein the successive fibre strands in the radial direction intersect each other in the opposite direction. 
     
     
         4 . The guide roller for wires as recited in  claim 2 , wherein the coating support and/or the stabilising support comprise at least one ply that consists of fibre strands stuck together with synthetic resin and extends essentially in the circumferential direction. 
     
     
         5 . The guide roller for wires as recited in  claim 1 , wherein the stabilising support and the coating support have constructions that differ from one another, providing that the radial layer thickness of the stabilising support is at least three times greater than that of the coating support. 
     
     
         6 . The guide roller for wires as recited in  claim 1 , wherein the stabilising support and the coating support have constructions that are the same as one another, providing that the radial layer thickness of the stabilising support is at least five times greater than that of the coating support. 
     
     
         7 . The guide roller for wires as recited in  claim 1 , wherein the coating support has a wall thickness equal to 0.5 to 8% of the associated outer diameter. 
     
     
         8 . The guide roller for wires as recited in  claim 1 , wherein the coating support has a wall thickness equal to 1 to 3% of the associated outer diameter. 
     
     
         9 . The guide roller for wires as recited in  claim 1 , wherein the hub part is in contact with the stabilising support at least radially from the inside at least in the area of the frontal face ends thereof via radial flanges. 
     
     
         10 . The guide roller for wires as recited in  claim 1 , wherein each of the frontal face flanges of the hub part is furnished with a collar protruding radially outwards and that the collars cover the frontal face of the stabilising support. 
     
     
         11 . The guide roller for wires as recited in  claim 10 , wherein the collars are delimited on the outside by circumferential surfaces that progressively and continuously complete the circumferential surface of the stabilising support in the manner of a notional extension. 
     
     
         12 . The guide roller for wires as recited in  claim 1 , wherein the stabilising support is supported between the frontal face flanges by at least one additional flange of the hub part. 
     
     
         13 . The guide roller for wires as recited in  claim 1 , wherein the flanges of the hub part and the stabilising support are stuck together with synthetic resin or welded together. 
     
     
         14 . The guide roller for wires as recited in  claim 1 , wherein the stabilising support is delimited on the outside by a cylindrical surface that is calibrated by a grinding process. 
     
     
         15 . The guide roller for wires as recited in  claim 1 , wherein the coating support is delimited on the outside by a cylindrical surface that is calibrated by a grinding process. 
     
     
         16 . The guide roller for wires as recited in  claim 15 , wherein the cylindrical surface is provided with a relief-type profile by a grinding process and/or by a peel ply. 
     
     
         17 . The guide roller for wires as recited in  claim 1 , wherein the coating support with the fixed coating securely attached thereto and the guide grooves for wires incorporated therein is intended for one-time use only.
