【Abstract】 An automatic retractable mechanical transmission device is proposed. According to the mission arrangement, the aircraft such as small satellites need to extend their antennas to the designated position and retract in time and accurately. According to the characteristics of the space environment, the telescopic device is required to be lightweight, highly diamagnetic, high-strength and high-reliability. The micro-automatic telescopic device adopts a double-coil telescopic mechanism to realize large-stroke stretching and recovery, and reduces the overall size of the device as much as possible to reduce the quality of the device. And based on the complex environment in space, after the finite element analysis, the material shape and structural shape of the device are adjusted.更多还原
