Abstract
In order to improve a refrigerant compressor comprising an overall casing, an electric motor disposed in the overall casing with a stator and a rotor which is mounted on a drive shaft, and also a screw compressor disposed in the overall casing, one compressor screw of which is mounted on the drive shaft, which is rotatably mounted in the overall casing by a first radial bearing between the rotor and the compressor screw and a second radial bearing disposed on a side of the compressor screw lying opposite the first radial bearing, in such a way that the risk of the stator being touched by the rotor no longer occurs, it is proposed that the drive shaft is mounted in the overall casing by a third radial bearing which is disposed on a side of the rotor lying opposite the first radial bearing, and that a drive portion of the drive shaft which extends between the first radial bearing and the third radial bearing is formed in such a way as to compensate for alignment errors between the three radial bearings.
