The invention relates to the technical field of aerospace, and discloses a slow release mechanism which comprises a volute spiral spring, a stop ring, a wobble wheel, a main wheel and a shell. One end of the shell is open, the check ring is arranged at the opening, the volute spiral spring is located on the side, away from the shell, of the check ring, and the volute spiral spring, the check ring, the wobble wheel, the main wheel and the shell are coaxially arranged through the rotating shaft. Wherein the fixed end of the volute spiral spring is connected with the check ring, the release end of the volute spiral spring is connected with the rotating shaft to drive the rotating shaft to rotate, the main wheel fixedly sleeves the rotating shaft, and the wobble wheel rotatably sleeves the rotating shaft and is connected with the check ring through the extension spring. In addition, a reciprocating ball is arranged among the main wheel, the shell and the wobble wheel, when the ball is located at the first position, the wobble wheel and the main wheel are relatively fixed, the extension spring can reduce the rotating speed of the wobble wheel, after the wobble wheel rotates relative to the check ring and abuts against the limiting part of the check ring, the ball is located at the second position, the main wheel and the shell are relatively fixed, and the ball reciprocates back and forth. Therefore, the speed of the main wheel is reduced.
本发明涉及航空航天技术领域,公开一种慢速释放机构,包括涡卷弹簧、止挡圈、摆动轮、主轮和壳体。壳体一端为敞口,止挡圈设置于敞口处,涡卷弹簧位于止挡圈背离壳体的一侧,且通过回转轴与止挡圈、摆动轮、主轮及壳体同轴设置。其中,涡卷弹簧的固定端连接止挡圈,释放端连接回转轴,以驱动回转轴转动,而主轮固定套设于回转轴上,摆动轮转动套设于回转轴上且通过拉伸弹簧与止挡圈连接。另外,主轮和壳体及摆动轮之间具有往返的球珠,球珠位于第一位置时,摆动轮和主轮相对固定,拉伸弹簧可降低摆动轮的转动速度,摆动轮相对止挡圈转动并抵接止挡圈的限位部后,球珠位于第二位置,主轮和壳体相对固定,球珠来回往返,以此实现主轮速度的降低。
