二、主机结构

II.        Main engine structure

由上横梁、中横梁、下横梁及底面板通过两对滚珠丝杠和立柱构成框架结构。由全数字交流伺服电机驱动减速机及同步齿型带，带动两对高精度无间隙的精密滚珠丝杠转动，驱动横梁上下移动。

The engine structure is formed by the upper beam, the middle beam, the lower beam and the bottom panel with two pairs of ball screw-rod and a vertical column. The all-digital AC motor drives the reducer and the synchronic gear belt, so as to turn two pairs of high-precision and seamless ball screw-rod, and to make the beam move up and down.
