ANALYSIS OF NUMBER OF OIL-POCKETS IN ONE SLIDE SURFACE OF LIQUID HYDROSTATIC SLIDE

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.
