Abstract

The invention relates to a repeatable locking device for a magnetically suspended flywheel, which comprises a flywheel system, a driving mechanism and a locking mechanism, wherein the locking mechanism is arranged outside a flywheel rotor and is fixed to a flywheel base through a fastening bolt. The flywheel system mainly comprises a flywheel stator shaft, a flywheel rotor and a base; the driving mechanism mainly comprises a fixed plate, a left bearing pressure ring, an upper bearing pressure ring, a motor, a worm, a coupling joint, a worm wheel, a fixed pole, a locking fork, a spherical nut, a worm wheel link rod and a bearing; and the locking mechanism mainly comprises a spring chip seat, a spring chip, a spring chip body, a small pole, a steel rope and a connecting pole. The locking device protects a magnetically suspended flywheel system, and has the advantages of repeatable use, high reliability, simple structure and the like.

Description

technical field [0001] The invention relates to a reusable locking device for a magnetic levitation flywheel, which has the advantages of reusability, high reliability, low power consumption, simple structure, etc., and can be used as a protection device for a magnetic levitation flywheel system. Background technique [0002] The magnetic levitation flywheel is a long-life, high-precision spacecraft attitude control actuator. The spacecraft will generate severe vibration and shock during launch. Since the magnetic levitation flywheel adopts magnetic bearing technology, there is a gap between the stator and the rotor. In order to prevent damage to the flywheel system, an additional locking device is required to protect it; in addition, when When the maglev flywheel enters the predetermined orbit, the flywheel rotor system needs to be released to facilitate its work. Since the maglev flywheel needs to pass a series of environmental tests (frequency sweep, vibration, shock, ce...
