一、导轨结构以英国Charles Churchill制造厂设计的具有浮动支承的闭式液体静压导轨为例子(如图1所示),来分析其结构特点。[参考资料2]。在不动的床身1上有主支承导轨面2和辅助导轨面3,在移动的工作台上,有相对应的主支承导轨面4和辅助导轨面5。而导轨面5是开在浮动支承7上的,这个浮动支承在垂直方向上可以自由移动,而且在油腔8和导轨5油腔的压力作用下,处于某一个平衡状态。为防止漏油,油腔8具有密封圈12。来自油泵 First, the rail structure British Charles Churchill factory designed with floating support closed hydrostatic rail as an example (Figure 1), to analyze the structural characteristics. [Reference 2]. The fixed bed 1 has a main support rail surface 2 and an auxiliary rail surface 3. On the moving table, there is a corresponding main support rail surface 4 and an auxiliary rail surface 5. While the guide surface 5 is opened on the floating support 7, which is freely movable in the vertical direction and is under a certain equilibrium state under the pressure of the oil chamber 8 and the oil chamber of the guide rail 5. To prevent oil leakage, the oil chamber 8 has a seal ring 12. From the oil pump
