| titleOfInvention | Permanent-magnetic passive axial magnetic suspension bearing with passive damping effect |
| abstract | The invention discloses a permanent-magnetic passive axial magnetic suspension bearing with passive damping effect. The magnetic bearing is split, and consists of a static part and a movable part. The static part comprises a stator bearing mounting sleeve, a stator damping mounting sleeve, stator magnetic rings, stator permanent magnets and a stator damping permanent magnet; and the movable part has hollow cup structure, and comprises a rotor shaft, a hollow cup rotor, rotor teeth and a damping copper bush. In the static part, three stator permanent magnets and four stator magnetic rings are sequentially arranged across in the axial direction, arranged on the stator bearing mounting sleeve together and used for providing rigidity for a system. The stator damping permanent magnet consists of three permanent magnets in a Halbach magnetizing mode, arranged on the stator damping mounting sleeve and used for providing damping for the system. According to the magnetic suspension bearing, anaxial sensor and a control system are saved, the volume is reduced, the weight is lightened, and the loss is eliminated. Through the passive damping structure of the magnetic suspension bearing, the oscillation of a rotor can be quickly attenuated, and the reliability of the system is improved. |
