Embodiment Construction
[0015] Preferred embodiments of the present invention are given below and described in conjunction with the accompanying drawings.
[0016] Such as figure 1 As shown, an auxiliary bearing for a vertical maglev flywheel rotor includes a support base 1, a damping ring 2, a stop screw 3, an angular contact ball bearing 4, a bearing sleeve 5, a shaft sleeve 6, a buffer body 7, and screws 8 and 9 , Lock nut 10, lock plate 11, bearing gland 12, buffer body gland 13. Among them, the bearing sleeve 5, the double-row angular contact ball bearing 4, the lock nut 10, the buffer body 7, and the bearing gland 12 form the body of the rotating part; the support seat 1 is fixedly connected with the fixed support on the rotor shell of the magnetic levitation flywheel; the shaft sleeve 6 The inner surface is tightly matched with the end of the flywheel rotor shaft, and the outer surface is composed of a cylindrical surface and a conical surface; it is made of wear-resistant materials such as b...

The invention aims at disclosing an auxiliary bearing of a vertical magnetic suspension flywheel rotor, which absorbs an impact energy generated when a rotor drops by means of a buffer body arranged between a support base and double rows of angular contact ball bearings and provided with a rubber damping ring. A shaft sleeve and a bearing sleeve with cylindrical and conical contact surfaces are additionally arranged between a rotor shaft and a bearing inner sleeve, and the shaft sleeve, the bearing sleeve, the double rows of angular contact ball bearings and the buffer body are packaged in the support base, a bearing gland and a buffer body gland to form the modular auxiliary bearing. The auxiliary bearings are used in pairs, and respectively arranged at two ends of the suspension flywheel rotor to form a safe and reliable support when an energy-storing flywheel rotor rotates, drops and stands still at a high speed. The auxiliary bearing has the advantages of convenience in use, self centering, damping vibration attenuation, serialization and the like.
Description
technical field [0001] An auxiliary bearing for a vertical magnetic levitation flywheel rotor, which is used to solve the support problem caused by the magnetic levitation flywheel rotor in a flywheel energy storage system when it is stationary or lands due to an overload or failure of the magnetic bearing system; it belongs to the field of rotating parts and bearings other than mechanical engineering transmission components . Background technique [0002] As a kind of mechanical battery, the flywheel energy storage system has been successfully applied to the uninterruptible power supply (UPS) system. It has the advantages of high specific energy and specific efficiency, rapid charge and discharge without affecting the service life, clean and environmentally friendly, and long service life. It also has broad application prospects in the fields of renewable energy photovoltaic power generation and wind power generation peak regulation, as well as hybrid electric vehicles. ...
