Definitions
- FIG. 1 shows a longitudinal section through a bearing arrangement with a radial support designed as a roller bearing and an axial support designed as a four-point bearing in a longitudinal section
- the bearing arrangement 1 shows a bearing arrangement 1 for the radial and axial mounting of a shaft 2 in a housing 3 or in a housing 4.
- the bearing arrangement 1 has a bearing 6 designed as a radial support 5 in the form of a roller bearing and a bearing acting as an axial support 7 8 in the form of a four-point bearing.
- the bearing arrangement 1 supports rotors (not shown) of a screw compressor.
- An outer bearing ring 9 of the radial support 5 is axially opposite an outer bearing ring 10 of the axial support 7.
- the bearing ring 9 is pressed into the bore 11 designed as a bearing seat and thus secured against rotation relative to the housing 3 or 4.
- the bearing ring 10 is separated from the housing 3 by an air gap 12 and is thus arranged without contact with the bearing seat.
- Bearings 6 and 8 are roller bearings.
- the bearing 6 consists of the bearing ring 9, rollers 20, a cage 21 and an inner ring 22.
- the bearing 6 is designed without an inner ring, so that the rollers 20 run on the shaft 2.
- the bearing 8 consists of the bearing ring 10, balls 23, a cage 24 and two inner rings 16 and 25.
- the shaft 2 is rotatably mounted to the housing 3, 4 by means of the bearing arrangement 1.
- the housing 3, 4 is rotatably mounted to the shaft 2 by means of the bearing arrangement.
- FIG. 4 shows an exemplary embodiment of an axial support 7 in the form of an angular contact ball bearing.
- the outer bearing ring 26 is provided with a retaining groove 27 into which a flat wedge 28, which is only indicated, engages.
- the holding groove 27 has a side wall 29 oriented perpendicular to the axis of rotation 19 and facing in the axial direction and two mutually opposite one another transversely to the axial direction. overlying and aligned side walls 30.
- a positive locking device with a radial support, not shown, can be produced via the flat wedge 28.
- the bearing ring 31 of an axial support 7 designed as an angular contact ball bearing according to FIG. 5 has an axial bore 32.
- a pin 33 (only indicated) engages in the axial bore 32, via which the bearing ring 31 is positively connected to a bearing ring (not shown) of a radial support in the circumferential direction in the axis of rotation 19.
- a deep groove ball bearing 33 designed as an axial support 7 is shown in FIG.
- the inner bearing ring 34 of the deep groove ball bearing is provided with a keyway 35.
- a wedge 36 engaging in the keyway 35 positively engages in a corresponding recess in an inner ring of a radial support, not shown, so that the supports are coupled to one another via the inner rings in this case.
