Definitions
- hood 50 arises in that it a circular cylindrical, in the axial direction against has projection 53 projecting from the outside, which has a bearing 54 records.
- This bearing carries the pulley 19, which rotatably by means of a radially elastic element 55 the drive shaft 24 is connected.
- This enables the a drive belt, not shown here Radial force are supported on the extension 53; the Drive shaft 24 is only by the drive torque charged.
- a Rolling bearing 58 include, via which the drive shaft 24th is mounted on the side wall 28.
- pooling inlets 12, 12 'by means of the hood 50 is created by guiding the Working medium past roller bearing 58. This is in the Machine operation heated by the shaft 24. Because now through the hood 50 part of the working medium - e.g. cold intake air - flowing past extensions 56, 56 ', these are cooled and since they have the outer ring 57 of the Rolling bearing 58 include, cool this.
