Space flexible arm tail end tool box pressing and anti-radiation protection mechanism

Abstract

The invention provides a space flexible arm tail end tool box pressing and anti-radiation protection mechanism, belonging to the technical field of tool box pressing and anti-radiation protection. Ananti-radiation cover plate is connected with a transmission shaft through a screw; a position detection micro switch, bearing blocks and an L-shaped motor base are connected to a fixed base by screws;the left end of the transmission shaft is connected with a drive motor and a reducer assembly through a coupling, the drive motor and the reducer assembly are connected to the L-shaped motor base through a heat insulating pad by bolts; a limit micro switch is connected to the bearing blocks by screws, and deep groove ball bearings are mounted on the bearing blocks, and the transmission shaft is mounted on a bearing through positioning parts such as a right bearing end cap, a left bearing end cap and a shaft sleeve. According to the invention, relatively accurate pre-tightening force can be applied, assembly and adjustment are convenient, and no impact and vibration during unlocking are caused; smooth in and out and anti-radiation protection of a tail end tool box can be realized; and thetail end of a flexible arm cannot be thrown out under the effect of large inertia force.

Description

technical field [0001] The invention relates to a tool box compression and anti-radiation protection mechanism at the end of a space flexible arm, and belongs to the technical field of tool box compression and anti-radiation protection. Background technique [0002] The world launches an average of 80-130 satellites per year, but 2-3 satellites fail to enter orbit correctly, and 5-10 satellites correctly enter orbit, and 5-10 fail at the beginning of their life (the first 30 days after entering orbit) , which resulted in huge economic losses. For example, after my country's Xinnuo-2 satellite was launched on October 29, 2006, although the satellite's orbit was successfully determined, and the satellite's measurement and control, attitude and orbit control subsystems were in good condition, however, due to the solar sail The second deployment of the board and the deployment of the antenna were not completed, and the satellite could not work normally. This satellite, which cos...

[0002] The world launches an average of 80-130 satellites per year, but 2-3 satellites fail to enter orbit correctly, and 5-10 satellites correctly enter orbit, and 5-10 fail at the beginning of their life (the first 30 days after entering orbit) , which resulted in huge economic losses

For example, after my country's Xinnuo-2 satellite was launched on October 29, 2006, although the satellite's orbit was successfully determined, and the satellite's measurement and control, attitude and orbit control subsystems were in good condition, however, due to the solar sail The second deployment of the board and the deployment of the antenna were not completed, and the satellite could not work normally. This satellite, which cost 2 billion yuan and had a design life of 15 years, immediately became a waste star.
