The basic structure of the rolling bearing

    Sliding bearings developed on the basis of the rolling bearing, its working principle is based on rolling friction instead of sliding friction, generally consists of two rings, a set of scrolling, and a maintain a frame composed of highly versatile, standardized, serialized extent is very high mechanical basic parts. All kinds of machinery have different working conditions, Rolling in the capacity of the structure and use of performance have raised variety of different requirements. To this end, the rolling bearing needs a variety of structures. However, the basic structure of the inner ring, outer ring, rolling element and cage composed.


The role of the various parts in the bearing are:

For radial bearings, the inner ring is usually a tight fit with the shaft, and together with the shaft running, usually bearing or mechanical shell hole, the outer into the transition with the played the supporting role. However, in some cases, the outer operation, fixed inner ring from the supporting role or the inner ring, outer ring operation at the same time. Thrust bearing, and shaft tight fit with the movement of said shaft ring, bearing or mechanical shell hole into the transition with the said seat and from the supporting role. Within the bearing, the rolling element (ball, roller or needle) usually with the cage arranged evenly between the two rings for rolling motion, its shape,
