Rolling bearings consist of an outer ring and an inner ring, rolling elements, and a cage, and their load-bearing capacity depends on the size of the rolling elements. There are many factors that affect the load-bearing capacity of liquid dynamic pressure bearings and sliding bearings. For example, in the case of wide rib ratio eccentricity relative clearance, the oil film bearing capacity of sliding bearings does not increase under different working loads, and the overnight diaphragm formed by the dynamic pressure of the nail and liquid lubricant of the multi liquid East Asian bearing is not improved. The liquid lubricant that separates the two friction surfaces into a sliding bearing under load is brought in by the relative motion of the two friction surfaces. Between the friction surfaces.
