摘要
目前液体静压导轨的导轨面内一般设计成对称单行、若干列油腔。油腔的数目（即列数）是液体静压导轨设计中的关键,对导轨的动态、静态性能都有着较大的影响。以液体静压导轨的单一导轨面为研究对象,分别作用垂直和倾覆载荷,推导了导轨的承载能力、静刚度与油腔数目的数学关系式,并进行了相应的分析。以工程中的滑板系统为例,滑板导轨面内分别对称设计单行,2列~6列油腔的五种方案。以滑板的承载能力、静刚度为性能依据,对五种方案进行对比分析,结果发现设计成单行、3列油腔时滑板的性能最佳。
At present,the oil pockets in the slide surface of a liquid hydrostatic slide system are symmetrically arranged in one row and several columns.The number of the oil pockets is the key to design the hydrostatic slide,and makes full impact on the performance of the hydrostatic slide.Based on one slide surface of the hydrostatic slide,under the vertical load and the overturning load separately,the relationship between the bearing capacity,the static stiffness and the number of the oil pocket is derived and analyzed.Take example for a sliding plate used usually in practical engineering,five schemes are analyzed and compared,which are about that the oil pockets in a slide surface are arranged in one row and from two to six columns.The conclusion suggests that it is best to arrange the oil pockets in one row and three columns.
