Abstract

The invention provides a lever-type repeatable locking device for a magnetically suspended flywheel. The locking device mainly comprises a flywheel system, a transmission mechanism and a lever-type locking mechanism, wherein the transmission mechanism and the lever-type locking mechanism are positioned under the radial inner side of the inner edge of a flywheel rotor and fixed on a flywheel base through tightening screws; the flywheel system mainly comprises a flywheel stator shaft, a flywheel rotor and a base; the transmission mechanism mainly comprises a fixed plate, a left bearing pressurering, a guide plate, a lead screw worm-wheel shaft, a left lock fork, a right lock fork, a worm, an upper bearing pressure ring, a worm gear wheel, a motor pinion, a motor and a bearing; and the lever-type locking mechanism mainly comprises a lock base, a lock shaft, a locknut, a locking bar, an anti-vibration pad, an unlocking spring, a steel wire rope and a connection column. The locking deviceprotects the suspended flywheel system and has the advantages of reusability, easy control, low power consumption, high reliability, great locking force, capability of preventing generation of redundancy and the like.

Description

technical field [0001] The invention relates to a lever-type reusable locking device for a magnetic levitation flywheel, which has the advantages of being reusable, easy to control, low power consumption, high reliability, large locking force, and can prevent the generation of redundant objects, etc., and can be used as a magnetic levitation flywheel System protection device. Background technique [0002] Magnetic levitation flywheel is a new type of spacecraft attitude control system. Compared with the flywheel supported by mechanical bearings, it has obvious advantages in control accuracy and service life. It is an ideal inertial actuator for high-precision earth observation satellite attitude control. When the magnetic levitation flywheel is working, the rotor is not directly rigidly connected with the stator by mechanical bearings, but elastically supported within a certain magnetic protection gap. Therefore, it must be protected by an additional locking device. In the...
