The stiffness of the polar axis' hydrostatic oil pads system in three directions was represented by the stiffness value of a single oil pad in two types of cylindrical and spherical journal.
用单油垫的油膜刚度值来表示柱面和球面轴颈两种极轴静压支承系统三个方向的刚度。
Minor wear and tear in the journal, simply press out the old bushings with new bushings, and revised from time-axis in general, it can get back to the gap with the extent permitted.
在轴颈磨损轻微时，只需压出旧衬套换上新衬套，而轴一般可不修，这样配合间隙可恢复到允许的范围内。
