Abstract

A screw compressor system for a utility vehicle has at least one screw compressor, at least one screw compressor drive with an output shaft, at least one driven screw with a screw drive shaft section. The output shaft and the screw drive shaft section are essentially coaxial.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . A screw compressor system for a utility vehicle, comprising:
 at least one screw compressor;   at least one screw compressor drive with an output shaft; and   at least one driven screw with a screw drive shaft portion, wherein   the output shaft and the screw drive shaft portion are substantially coaxial.   
     
     
         2 . The screw compressor system as claimed in  claim 1 , wherein
 a compensating coupling is provided between the output shaft and the screw drive shaft portion.   
     
     
         3 . The screw compressor system as claimed in  claim 1 , wherein
 the screw drive shaft portion has a first bearing portion.   
     
     
         4 . The screw compressor system as claimed in  claim 3 , wherein
 a radial bearing is arranged on the first bearing portion.   
     
     
         5 . The screw compressor system as claimed in  claim 4 , wherein
 the radial bearing is in the form of a needle-roller bearing.   
     
     
         6 . The screw compressor system as claimed in  claim 4 , wherein
 the radial bearing has no inner ring.   
     
     
         7 . The screw compressor system as claimed in  claim 4 , wherein
 rolling elements of the radial bearing run directly on a surface of the first bearing portion.   
     
     
         8 . The screw compressor system as claimed in  claim 5 , wherein
 rolling elements of the radial bearing run directly on a surface of the first bearing portion.   
     
     
         9 . The screw compressor system as claimed in  claim 6 , wherein
 rolling elements of the radial bearing run directly on a surface of the first bearing portion.   
     
     
         10 . The screw compressor system as claimed in  claim 3 , wherein
 the driven screw has a screw portion and a second bearing portion in addition to the screw drive shaft portion, and   the screw portion is situated between the screw drive shaft portion and the second bearing portion.   
     
     
         11 . The screw compressor system as claimed in  claim 10 , wherein
 a bearing for accommodating axial and radial forces is arranged on the second bearing portion.   
     
     
         12 . The screw compressor system as claimed in  claim 1 , wherein
 a further screw that meshes with the driven screw has a substantially identical bearing arrangement to the driven screw.   
     
     
         13 . The screw compressor system as claimed in  claim 11 , wherein
 a further screw that meshes with the driven screw has a substantially identical bearing arrangement to the driven screw.
