Radial Shaft Seal

Abstract

A radial shaft seal has a support body and at least one sealing element that is a part produced separate from the support body and is connected to the support body by an adhesive connection. A static seal part that is a part separate from the sealing element and is arranged on a wall of the support body is provided. Alternatively, the sealing element comprises an integral static seal part and the static seal part is formed by a radially projecting edge of the holding part of the sealing element that projects radially past the wall of the support body.

What is claimed is: 
     
         1 . A radial shaft seal comprising:
 a support body;   at least one sealing element;   wherein the at least one sealing element is a part produced separate from the support body and is connected to the support body by an adhesive connection;   a static seal part that is a part separate from the at least one sealing element and is arranged on a wall of the support body.   
     
     
         2 . The radial shaft seal according to  claim 1 , wherein the at least one sealing element is comprised of rubber or polyfluorocarbon. 
     
     
         3 . The radial shaft seal according to  claim 1 , wherein the at least one sealing element is comprised of polytetrafluoroethylene. 
     
     
         4 . The radial shaft seal according to  claim 1 , wherein the static seal part is mounted in a receptacle of the support body. 
     
     
         5 . The radial shaft seal according to  claim 4 , wherein the receptacle is a circumferential groove in the wall of the support body. 
     
     
         6 . The radial shaft seal according to  claim 1 , wherein the at least one sealing element has a holding part and the holding part is connected to a bottom of the support body. 
     
     
         7 . The radial shaft seal according to  claim 6 , wherein the holding part is glued to the bottom of the support body. 
     
     
         8 . The radial shaft seal according to  claim 6 , wherein the holding part is attached to an inner side of the bottom of the support body. 
     
     
         9 . The radial shaft seal according to  claim 6 , wherein the holding part is attached to an outer side of the bottom of the support body. 
     
     
         10 . The radial shaft seal according to  claim 6 , wherein the holding part extends essentially across the entire radial extension of the bottom of the support body. 
     
     
         11 . The radial shaft seal according to  claim 1 , wherein the at least one sealing element has a dynamic seal part and a protective lip, wherein the protective lip and the dynamic seal part point in opposite directions. 
     
     
         12 . The radial shaft seal according to  claim 10 , wherein the dynamic seal part has a return device. 
     
     
         13 . A radial shaft seal comprising:
 a support body having a wall;   at least one sealing element;   wherein the at least one sealing element is a part produced separate from the support body and is connected to the support body by an adhesive connection;   wherein the at least one sealing element comprises a holding part and an integral static seal part;   wherein the static seal part is formed by a radially projecting edge of the holding part of the sealing element and the radially projecting edge projects radially past the wall of the support body.   
     
     
         14 . The radial shaft seal according to  claim 13 , wherein the at least one sealing element is comprised of rubber or of polyfluorocarbon. 
     
     
         15 . The radial shaft seal according to  claim 13 , wherein the at least one sealing element is comprised of polytetrafluoroethylene. 
     
     
         16 . The radial shaft seal according to  claim 13 , wherein the holding part of the at least one sealing element is connected to a bottom of the support body. 
     
     
         17 . The radial shaft seal according to  claim 16 , wherein the holding part is glued to the bottom of the support body. 
     
     
         18 . The radial shaft seal according to  claim 16 , wherein the holding part is attached to an outer side of the bottom of the support body. 
     
     
         19 . The radial shaft seal according to  claim 13 , wherein the at least one sealing element has a dynamic seal part and a protective lip, wherein the protective lip and the dynamic seal part point in opposite directions. 
     
     
         20 . The radial shaft seal according to  claim 19 , wherein the dynamic seal part has a return conveying device. 
     
     
         21 . The radial shaft seal according to  claim 16 , wherein the holding part of the at least one sealing element extends essentially across the entire radial extension of the bottom of the support body.
