Abstract

The invention provides a space constant torque passive driving device comprising a first mounting portion, a second mounting portion, a spring fixing disc, a spring guiding disc and an energy storage spring. The first mounting portion is connected with the second mounting portion through a shaft. The spring fixing disc is connected with the first mounting portion. The spring guiding disc is connected with the second mounting portion. The energy storage spring is connected with the spring fixing disc and the spring guiding disc respectively. The pace constant torque passive driving device has the advantages of constant torque, small impact, wide torque outputting range and high generality.

Description

technical field [0001] The invention relates to a passive drive mechanism, in particular to a space constant moment passive drive device. Background technique [0002] As the contradiction between the requirements of multi-function and large size of the spacecraft and the volume limit of the payload compartment of the vehicle becomes more and more acute, the spacecraft needs to use a large number of unfolded structures, that is, it is folded before entering orbit to reduce the envelope, and unfolded after entering orbit. Into the working state to effectively expand the function of the spacecraft. In order to complete the deployment function, the unfolded structure must be equipped with a reliable and stable drive device, and the passive drive device with one-dimensional rotation function is the most commonly used device in space missions. [0003] According to the literature search of the prior art, it is found that the passive driving devices currently used mostly use spir...
