Magnetic suspension bearing rotor and magnetic suspension rotor system

Abstract

The invention relates to the technical field of magnetic suspension, in particular to a magnetic suspension bearing rotor and a magnetic suspension rotor system. The magnetic suspension bearing rotorcomprises an integral magnetic conductive ring. A plurality of annular grooves are formed in the magnetic conductive ring in the axial direction of the magnetic conductive ring at intervals. Openingsof the annular grooves all face the outer side of the magnetic conductive ring. The magnetic conductive ring of the magnetic suspension bearing rotor provided by the invention is of an integrated structure and is provided with the annular grooves with the openings facing outwards; the problem of vortex caused by a complete metal ring adopted for an existing magnetic suspension bearing rotor is solved, and the problem that the existing magnetic suspension bearing rotor is of a laminated assembly structure and can hardly adapt to the high-speed operating environment is solved, and processing andassembling are easy. As the structural strength of the magnetic conductive ring is high, the high value of interference fit can be adopted between the magnetic conductive ring and a rotary shaft. Accordingly, the magnetic conductive ring and the rotary shaft are connected more reliably, and the magnetic suspension bearing rotor can adapt to the high-speed operating environment.

Description

technical field [0001] The invention relates to the technical field of magnetic suspension, in particular to a magnetic suspension bearing rotor and a magnetic suspension rotor system. Background technique [0002] The magnetic bearing rotor will generate eddy current loss when it rotates at high speed. In order to reduce the eddy current loss, the traditional method is to form the magnetic bearing rotor by stacking silicon steel sheets. On the one hand, the preparation process of the silicon steel sheet is complicated; on the other hand, the cooperation between the silicon steel sheet iron core and the rotor shaft cannot achieve an effective interference fit, so that at ultra-high speeds, the tightness of the iron core and the rotor shaft will be destroyed. It is easy to cause the loosening of the structural connection during the operation of the equipment, and if the bonding between the silicon steel sheets becomes loose, it will cause obvious vibration and loud noise duri...
