MACHINE HAVING A BACK-UP BEARING HAVING A HYBRID ARRANGEMENT |
摘要 |
A machine having a stator and a rotor having a rotor shaft supported in bearings, such that the rotor is rotatable about a rotation axis. The bearings are designed as active magnetic bearings in which the rotor is supported without contact. A respective back-up bearing is associated with each active magnetic bearing to catch the rotor when the respective active magnetic bearing fails. The respective back-up bearing has a bushing arranged on the rotor shaft and a sliding device arranged on the stator. The respective bushing has an inner ring arranged radially inside to fasten the bushing on the rotor shaft, and an outer ring that surrounds the inner ring radially outside and slides in the sliding device of the respective back-up bearing when the respective active magnetic bearing fails. The inner and outer rings are made of different materials and are connected to each other in a bonded manner. |
