| 1. | In the design , gear and spline were adopted , so symmetrical movement of ( collimator ’ s ) lead gates can be achieved easily , mechanical structure became more compact . worm was adopted to adjust mirrors accurately , and deflection of mirrors can be prevented in case of the external impacts or vibrations
采用齿轮齿条结构,实现铅门的对称开合运动,使子系统的机械结构更为紧凑,同时提高了定位精度;采用蜗轮蜗杆调解反光镜的角度,可以使反光镜的调节更精确,同时可以防止在外界振动或撞击下反光镜发生偏转。 |
