The objective of the invention is to provide an auxiliary support for a vertical magnetic suspension flywheel rotor. The auxiliary support comprises an upper auxiliary support assembly and a lower auxiliary support assembly, respectively located at an upper end and a lower end of a vertical flywheel rotor shaft; an upper supporting sleeve, a lower supporting sleeve and a lower bearing sleeve are respectively mounted between the rotor shaft and a bearing, the upper supporting sleeve and the lower supporting sleeve are respectively in interference fit with the shaft, the exterior surface of the lower supporting sleeve comprises an outer cylindrical surface and a conical surface, and the interior surface of the lower supporting sleeve comprises an inner cylindrical surface and a conical surface. The invention has the following beneficial effects: the auxiliary support can realize safe and reliable supporting of the energy storage flywheel rotor during high speed rotation, falling and standstill of the flywheel rotor and enables the rotor to rapidly enter to an automatic centering state in virtue of guiding of the conical surfaces when the flywheel rotor shaft falls, so impact and vibration are effectively reduced, thereby improving the service life, safety and reliability of a flywheel energy storage system.
Description
Technical field [0001] An auxiliary support for a vertical magnetic levitation flywheel rotor belongs to the field of rotating parts and bearings other than transmission elements of mechanical engineering. Background technique [0002] The use of flywheel energy storage has been widely used in various machinery and equipment, and its structural form is basically the use of metal flywheels, supported by ordinary mechanical bearings; the speed is generally low and has a large mass. [0003] With the advancement of science and technology, using the principle that energy storage is proportional to the square of the rotation speed, modern flywheel energy storage technology has been developed, thus forming a flywheel energy storage system. The flywheel energy storage system is mainly composed of composite material flywheel, motor / generator, electromagnetic bearing, energy conversion system and vacuum system. The motor / generator realizes the conversion of energy. When charging, it runs a...
