Compressor housing and method for assembling a compressor housing

Abstract

A compressor housing has a housing body that is embodied so as to be open at two opposing end faces of the housing body, and a base element which closes one of the two open end faces of the housing body in an assembled state of the compressor housing, the base element being frictionally secured in the assembled state with its outer peripheral surface against an inner peripheral surface of the housing body by means of an interference fit.

1 . A compressor housing comprising:
 a housing body that is embodied so as to be open at two opposing end faces of the housing body, and   a base element that closes one of the two open end faces of the housing body in an assembled state of the compressor housing,   wherein, in the assembled state, the base element is frictionally secured by means of an interference fit with its outer peripheral surface against an inner peripheral surface of the housing body.   
     
     
         2 . The compressor housing as set forth in  claim 1 , wherein the interference fit is formed by shrinking the housing body onto the base element. 
     
     
         3 . The compressor housing as set forth in  claim 1 , wherein the interference fit is formed through cold stretching of the base element. 
     
     
         4 . The compressor housing as set forth in  claim 1 , further comprising a weld seam applied at a junction between the housing body and the base element. 
     
     
         5 . The compressor housing as set forth in  claim 4 , wherein the weld seam is applied by means of a laser welding process. 
     
     
         6 . A method for assembling a compressor housing, comprising:
 Introducing a base element into a housing body having two opposing open end faces, and   frictionally securing the base element into the housing body with an outer peripheral surface of the base element against an inner peripheral surface of the housing body by means of an interference fit so that, in an assembled state of the compressor housing, the base element closes one of the two end faces of the housing body.   
     
     
         7 . The method as set forth in  claim 6 , further comprising forming the interference fit by heating and shrinking the housing body onto the outer peripheral surface of the base element. 
     
     
         8 . The method as set forth in  claim 6 , further comprising forming the interference fit by cooling the base element to a temperature below room temperature and, after the introduction of the cooled base element into the housing body, allowing the base element to expand during heating to room temperature until the base element abuts with its outer peripheral surface against the inner peripheral surface of the housing body. 
     
     
         9 . The method as set forth in  claim 6 , further comprising applying a weld seam at a junction between the housing body and the base element. 
     
     
         10 . The method as set forth in  claim 9 , wherein applying the weld seam is by means of a laser welding process.
