Machine having a back-up bearing having a hybrid arrangement |
| abstract |
The invention relates to a machine having a stator (1) and a rotor (2). The rotor (2) has a rotor shaft (3) which is supported in bearings (4), such that the rotor (2) can be rotated about an axis of rotation (5). The bearings (4) are designed as active magnetic bearings (4) in which the rotor (2) is supported without contact. A respective back-up bearing (6) is associated with each active magnetic bearing (4), by means of which back-up bearings the rotor (2) is caught if the respective active magnetic bearing (4) fails. The respective back-up bearing (6) has a bushing (7) arranged on the rotor shaft (3) and a sliding device (8) arranged on the stator (1). The respective bushing (7) has an inner ring (9) arranged radially inside, by means of which the bushing (7) is fastened to and retained on the rotor shaft (3). The respective bushing (7) has an outer ring (10) that surrounds the inner ring (9) radially outside, which outer ring slides in the sliding device (8) of the respective back-up bearing (6) if the respective active magnetic bearing (4) fails. The inner ring (9) and the outer ring (10) are made of different materials. The inner ring and the outer ring are connected to each other in a bonded manner. |
