A detachable magnetic levitation energy storage flywheel rotor

Abstract

The invention discloses a detachable magnetic suspension energy storage flywheel rotor, which relates to the detaching structure and the detaching technology for a flywheel rotor. The flywheel rotor shaft (14) is a multi-diameter shaft. The axial electromagnetic bearing thrust plate (6) is provided with threaded holes uniformly. The connection with the flywheel rotor shaft (14) is realized in such a manner as the threaded shaft is pressed in the axial direction. The auxiliary bearing rotor is uniformly distributed with threaded holes that are in interference fit with the flywheel rotor shaft (14). The electromagnetic bearing expansion sleeve and the energy storage flywheel (9) are assembled on the flywheel rotor shaft (14) via the expansion sleeve connection manner. The motor / generator rotor (10) are generally in interference fit with the flywheel rotor shaft (14), and are assembled via a thermal assembling method. The rotor of the invention can be detached conveniently, saving maintenance cost and shortening the manufacturing cycle. The rotor can be manufactured conveniently so as to easily ensure the manufacturing precision. As can be assembled conveniently, the working performances of the flywheel rotor can be ensured easily; and the problem with detaching the electromagnetic bearing rotor in large interference fit can be resolved.
