Rolling bearing developed with sliding bearing as the base; its working principle is to replace sliding friction with rolling friction; generally consists of two ferrules; a set of rolling elements and a cage are versatile, standardized, serialized Very high mechanical roots. Because various machines have different working conditions; there are different requirements for the rolling bearings in terms of load capacity, layout and function. For this reason, the rolling bearings need to have a wide range of layouts. However, the most fundamental layout consists of the inner ring, the outer ring, the roll body and the cage.
The effects of various parts in the bearing are:
Regarding the radial bearing; the inner ring generally cooperates with the shaft; and works with the shaft; the outer ring generally cooperates with the bearing seat or the mechanical housing hole; the support effect is provided; however; in some cases; the outer ring works The inner ring is fixed to support the effect or the inner ring and the outer ring are all working together. About the thrust bearing; the shaft ring which cooperates with the shaft and moves together; and the bearing seat or the mechanical housing hole cooperates with each other and supports the effect The seat ring. The rolling body (steel ball, roller or needle roller) is generally placed between the two ferrules in the bearing for rolling movement; its shape, size and quantity directly affect the load of the bearing. And the use of functions. The cage can not evenly separate the roll body; it can also guide the rotation of the roll body and improve the smooth function inside the bearing.
