A space flexible arm end tool box compression and anti-radiation protection mechanism

Abstract

The invention provides a space flexible arm end tool box compression and anti-radiation protection mechanism, which belongs to the technical field of tool box compression and anti-radiation protection. In the present invention, the anti-radiation cover is connected to the transmission shaft through screws; the position detection microswitch, the bearing seat and the L-shaped motor seat are connected to the fixed base through screws; the left end of the transmission shaft is connected to the drive motor and The reducer components are connected, the drive motor and reducer components are connected to the L-shaped motor base through bolts through the heat insulation pad; the limit micro switch is connected to the bearing base through screws, and deep groove ball bearings are installed on the bearing base, and the drive shaft passes through the left Positioning parts such as bearing end cover, right bearing end cover and shaft sleeve are installed on the bearing. The present invention can apply more accurate pre-tightening force, is convenient for assembly and adjustment, and when unlocking, there is no impact or vibration; it can realize the smooth entry and exit of the end tool box and radiation protection; it can prevent the end of the flexible arm from being affected by a large inertial force was thrown out.

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.
