Compressor

Abstract

The compressor of the present invention includes a mounting section which is arranged in the outer circumferential section of a compressing housing provided with a compressing chamber, the mounting section having insertion holes ( 61 a, 62 a ) into which a mounting bolt ( 64 ) is inserted, and the mounting section having a highly rigid section (bush) ( 63 ) for suppressing the deformation caused in the process of mounting the compressor.

1 . A compressor comprising: a compressing housing having a compressing chamber; a side housing arranged on one side of the compressing housing; an input shaft being rotated when it receives a drive force; a compressing mechanism arranged in the compressing chamber and drived when the input shaft is rotated; and a mounting section having an insertion hole, the mounting section being mounted on a body, on which the compressor is mounted, with a bolt, wherein the mounting section includes a highly rigid section, arranged in an outer circumferential section of the compressing housing, for suppressing deformation of the compressor which is caused in the process of mounting the compressor.  
     
     
         2 . A compressor comprising; a compressing housing having a compressing chamber; a side housing arranged on one side of the compressing housing: an input shaft being rotated when it receives a drive force; a compressing mechanism arranged in the compressing chamber and drived when the input shaft is rotated; and a mounting section having an insertion hole, the mounting section being mounted on a body, on which the compressor is mounted, with a bolt, wherein the mounting section includes at least a pair of parallel mounting pieces protruding from an outer circumferential section of the compressing housing, each mounting piece having an insertion hole into which a mounting bolt is coaxially inserted, and the mounting section also includes a bush, the rigidity of which is higher than that of the mounting pieces, inserted into between the mounting pieces.  
     
     
         3 . A compressor according to  claim 2 , wherein the bush is made of a material, the Young's modulus of which is higher than that of the mounting piece.  
     
     
         4 . A compressor according to  claim 3 , wherein the mounting piece is made of aluminum alloy and the bush is made of steel.  
     
     
         5 . A compressor according to  claim 1 , further comprising a second mounting section, arranged in an outer circumferential section of the side housing, having an insertion hole into which a mounting bolt is inserted.  
     
     
         6 . A compressor according to  claim 2 , further comprising a second mounting section, arranged in an outer circumferential section of the side housing, having an insertion hole into which a mounting bolt is inserted.  
     
     
         7 . A compressor according to  claim 5 , wherein the second mounting section is composed of cylindrical mounting bodies protruding in parallel with each other from at least two positions in the outer circumferential section of the side housing arranged on the front end side of the compressing housing.  
     
     
         8 . A compressor according to  claim 6 , wherein the second mounting section is composed of cylindrical mounting bodies protruding in parallel with each other from at least two positions in the outer circumferential section of the side housing arranged on the front end side of the compressing housing.  
     
     
         9 . A compressor according to  claim 1 , wherein the compressing chamber is a plurality of cylinders extending in the axial direction and arranged annularly, and the compressing mechanism is a piston slidably arranged in each cylinder of the compressing housing and drived for reciprocating each piston when the input shaft is rotated.  
     
     
         10 . A compressor according to  claim 2 , wherein the compressing chamber is a plurality of cylinders extending in the axial direction and arranged annularly, and the compressing mechanism is a piston slidably arranged in each cylinder of the compressing housing and drived for reciprocating each piston when the input shaft is rotated.
