Integrally geared compressor with adjustable intermediate gearwheel

Abstract

An integrally geared compressor including a casing, which can be separated at a separating joint into a first partial casing and a second partial casing, wherein the casing encloses a casing interior, a first shaft, which supports a first gearwheel and is mounted along a first axis in at least one first bearing, and a second shaft, which supports a second gearwheel and is mounted along a second axis in at least one third bearing is provided.

1 . An integrally geared compressor comprising
 a casing which can be split at a parting joint into a first casing part and a second casing part, which casing surrounds a casing internal space,   a first shaft which bears a first gearwheel and is mounted along a first axis in at least one first bearing,   a second shaft which bears a second gearwheel and is mounted along a second axis in at least one third bearing, wherein at least the third bearing has a third pillow block which entirely supports the bearing and in that the third pillow block is arranged entirely within the casing internal space and in that the third pillow block is releasably attached only to the first casing part, wherein the first casing part has a receiving shape for the third pillow block, in which the third pillow block is arranged with a shaped part.   
     
     
         2 . The integrally geared compressor as claimed in  claim 1 , wherein the first shaft is mounted in a first bearing and a second bearing, and the second shaft is mounted in a third bearing and a fourth bearing, wherein the fourth bearing is mounted in a fourth pillow block, wherein the fourth pillow block is arranged entirely within the casing inner space and the fourth pillow block is releasably attached only to the first casing part. 
     
     
         3 . The integrally geared compressor as claimed in  claim 1 , wherein the integrally geared compressor comprises a third shaft which is mounted in a fifth bearing and in a sixth bearing and bears a third gearwheel, wherein the first gearwheel meshes directly with the second gearwheel and wherein the second gearwheel meshes directly with the third gearwheel. 
     
     
         4 . The integrally geared compressor as claimed in  claim 3 , wherein the first shaft is fed out of the casing internal space and is designed as a shaft driven from outside, wherein the first gearwheel is bigger than the third gearwheel (GW 3 ). 
     
     
         5 . The integrally geared compressor as claimed in  claim 1 , wherein the third pillow block with the shaped part is arranged in the receiving shape with the interposition of orienting elements, wherein the orienting elements allow the shaped part to be oriented for two different spatial directions. 
     
     
         6 . The integrally geared compressor as claimed in  claim 3 , wherein the first shaft, the second shaft and the third shaft are not arranged in a common plane, with respect to their axes of rotation. 
     
     
         7 . The series of integrally geared compressors as claimed in  claim 1 , wherein the second gearwheels, which are borne by the second shaft, have different diameters to each other in the series, wherein the third pillow blocks are designed for a different position, in the series, of the second axis of the second shaft, wherein the first casing part has a receiving shape for the third pillow block, which receiving shape is identical for the entire series.
