Abstract

A self-spinning separation device is provided. one end of the self-spinning separation device is mounted on the vehicle end, one end of the self- spinning separation device fits with the star throughan axle hole, so that torque transmission is realized, separation angular velocity for microsatellite separation is provided. The device comprises a coil spring spinning assembly, wherein the coil spring spinning assembly comprises an adjustable torque coil spring and a detachable torque adjusting lever; the adjustable torque coil spring is used as an energy storage assembly, and the torque adjusting lever is rotated to different angles to realize the adjustment of the initial torque of the coil spring in different gears, so as to meet the different starting angular velocity requirements of different micro satellites. The self-spinning separation device provided by the invention has the characteristics of lightweight, compact structure and high reliability, and is a self-starting separation device with high application value in the field of micro satellites.

Description

technical field [0001] The invention relates to a spacecraft structure and mechanism, in particular to a self-spinning separation device applied to a microsatellite. Background technique [0002] With the increasing number of space activities, microsatellites with a weight of less than 50kg are more and more widely used in space activities due to their low cost, fast launch speed and flexible tasks. At present, microsatellites are generally launched by carrying. In some applications, it is necessary to have a certain initial angular velocity during the separation process of microsatellites, that is, spin-off separation according to requirements. Therefore, it is difficult for the conventional axis separating device for separating push rods to meet the requirements of spinning. SUMMARY OF THE INVENTION [0003] In view of the current demand for spinning microsatellites, the present invention provides a spinning separation device applied to microsatellites from the aspects ...
