Problems solved by technology

[0003] The existing reaction flywheels are usually sealed by welding or rubber rings. If they are sealed by welding, the process will be difficult. If they are sealed by rubber rings, the vacuum degree will be kept for a short time. Therefore, we propose a Reaction Flywheel Vacuum Maintaining Structure

Abstract

The invention belongs to the technical field of reaction flywheels, and particularly relates to a reaction flywheel vacuum degree maintaining structure which comprises a base and a sealing cover, and the base and the sealing cover are connected through a sealing assembly and then fixed through a connecting assembly. According to the preferable scheme of the reaction flywheel vacuum degree maintaining structure, the sealing assembly comprises a clamping plate, a first clamping groove, a rubber sealing ring, epoxy glue and a second clamping groove, the clamping plate is fixedly installed on the inner side of the top of the base, the first clamping groove is formed by the clamping plate and the top of the base, and the rubber sealing ring is fixedly installed on the inner side of the top of the base. A second clamping groove is formed in the inner wall of the bottom end of the sealing cover, and a clamping plate is clamped to the inner wall of the second clamping groove, the base and the sealing cover are connected through the sealing assembly, the sealing performance can be improved, the sealing time can be prolonged, and the technology difficulty is small.

Description

technical field [0001] The invention relates to the technical field of a reaction flywheel, in particular to a vacuum degree maintaining structure of a reaction flywheel. Background technique [0002] The reaction flywheel is the main executive component in the satellite attitude control system. By changing the momentum moment vector of the reaction flywheel, the momentum moment vector of the spacecraft can be changed, so as to achieve the purpose of satellite attitude control. When the reaction wheel is tested on the ground, the friction force generated by air resistance will have a negative impact on the life of the flywheel shaft. Keeping the vacuum of the flywheel can not only reduce the wear of the shaft during the test, but also get closer to the space environment to achieve better Therefore, it is very important to maintain the vacuum degree for the reaction product. [0003] The existing reaction flywheel is usually sealed by welding or rubber ring. If it is sealed ...
