Problems solved by technology

[0002] In the prior art magnetic levitation rotor support system, when the power is cut off, due to the phenomenon of falling and touching between the rotor shaft and the passive mechanical protection bearing, mechanical damage and noise occur. At the same time, due to the accumulation of mechanical damage, The dynamic balance of the high-speed rotor will be damaged and the service life of the rotor shaft will be reduced. Therefore, it is very necessary to set up an active magnetic levitation rotor shaft anti-drop protection mechanism

Embodiment Construction

[0017] The power-off protection mechanism of the magnetic levitation rotor support system of the present invention will be further described in detail with specific implementation methods and accompanying drawings:

[0018] according to figure 1 The power-off protection mechanism of the magnetic levitation rotor support system of the present invention is shown, which is composed of two electromagnets 1 that generate axial attraction force and one that can form an axial direction with the radial wall of the stator part 2 of the magnetic levitation rotor support system. Rotor shaft support composed of slidably fitted bearing sleeve 3, axial thrust spring 4 between the bearing sleeve and the axially opposite surface of the stator part, and mechanical bearing 5 seated on the bearing sleeve The switcher is opposed and sleeved on the periphery of the proximal end of the rotor shaft 6, and then the electromagnetically attracted radial magnetic suspension bearings 7 and 8 with an axia...

Abstract

The invention discloses a power-off protection mechanism of a magnetic suspension rotor support system. The power-off protection mechanism of the magnetic suspension rotor support system is formed by oppositely arranged two identical rotor support converters of the magnetic suspension rotor support system and near-end portions sleeved on rotor shaft levers. Each rotor support converter of the magnetic suspension rotor support system is formed by an axial attraction electromagnet (18), a ring sleeve part (24) and a mechanical bearing, wherein the axial attraction electromagnet (18) adsorbs the ring sleeve part, the ring sleeve part can form axial sliding match with a stator portion (19) of the magnetic suspension rotor support system, the axial attraction electromagnet (18) enables the ring sleeve part to pass through a groove of a central hole, the mechanical bearing is installed on each rotor shaft lever, and a cone-shaped inclined surface is arranged outside an outer ring of the mechanical bearing.

Description

Technical field: [0001] The invention relates to a protection mechanism for the rotor shaft when the magnetic levitation rotor support system is powered off. Background technique: [0002] In the prior art magnetic levitation rotor support system, when the power is cut off, due to the phenomenon of falling and touching between the rotor shaft and the passive mechanical protection bearing, mechanical damage and noise occur. At the same time, due to the accumulation of mechanical damage, The dynamic balance of the high-speed rotor will be damaged and the service life of the rotor shaft will be reduced. Therefore, it is very necessary to arrange an anti-drop protection mechanism for the active magnetic levitation rotor shaft. Invention content: [0003] The present invention is to provide a magnetic levitation rotor support system, which is used for the anti-drop protection mechanism of the magnetic levitation rotor shaft when the power is cut off. This causes the jacking fo...
