Paper Abstract

According to the focal depth and work environment of a space camera, a focusing mechanism is designed, which consists of precision screw ball transmission and linear bearing guidance and accuracy improving. The dynamic- strikeresistance, adaptability to temperature and vacuum are considered into the reliable design method. Furthermore, the linearity error, the structure stability and the mechanism work situation in high and low temperature are tested. The result is that the linearity error of the mechanism is less than 0.003mm, and the sway error of vertical way and level way of the mirror is less than 20". The linearity error of the mechanism and the sway error of the mirror remain unchanged after vibration test. The mechanism can work in the complex space environment.
