Mechanism for detecting torque performance of space torsion spring maintaining working state for long time

Abstract

The invention relates to a mechanism for detecting a torque performance of a space torsion spring maintaining a working state for a long time. The mechanism comprises a bottom plate, a fixing part, arotating part, and a stopping part. The fixing part comprises a fixing bracket and a horizontal shaft, wherein the fixing bracket is fixedly provided on the bottom plate, and the horizontal shaft is fixedly provided on the fixing bracket. The rotating part comprises a rotating cylinder and a turntable. The rotating cylinder is rotatably sleeved on the horizontal shaft. The rotating cylinder is sleeved with a torsion spring. One end of the torsion spring is fixedly connected to the fixing part, and the other end is fixedly connected to the rotating cylinder. The turntable is fixedly provided atan outer end of the rotating cylinder and rotatably provided on the bottom plate by the stopping part. According to the mechanism for detecting the torque performance of the space torsion spring maintaining a working state for a long time, the space torsion spring can be maintained at an arbitrary torsion angle for a long time, and the torque performance of the space torsion spring can be monitored by using a torque wrench or a tension gauge, so that the technical problem that in the prior art, the space torsion spring cannot be detected due to the long-term torsion state of the space torsionspring is solved.

Description

technical field [0001] The invention relates to a space torsion spring mechanism, in particular to a space torsion spring working state long-term storage torque performance monitoring mechanism. Background technique [0002] Compared with the active drive mechanism, the torsion spring is the power source of the passive drive mechanism, which has the advantages of stable torque, light weight, small size, no need for circuit control, and high reliability. Therefore, space torsion springs are widely used in passive deployment mechanisms such as solar cell array root hinges, inter-panel hinges, SAR antenna deployment hinges, and microwave imager antenna deployment mechanisms. [0003] The torque performance of the torsion spring is the key to the normal operation of the unfolding mechanism. In order to achieve the expected driving torque, the torsion spring is in a twisted state at a certain angle when the passive unfolding mechanism is in a retracted state and in a fully deplo...
