How Bearings Works – HXHV Bearing

Bearing has a vital and irreplaceable role in mechanical design, which involves a very wide range, it can be understood that there is no bearing, the shaft is a simple iron bar.  The following is a basic introduction to the working principle of bearings.  The rolling bearing developed on the basis of bearing, its working principle is rolling friction instead of sliding friction, generally consists of two rings, a group of rolling body and a cage composed of strong universality, standardization, high degree of serialization of mechanical foundation.  Due to the different working conditions of various machines, different requirements are put forward for rolling bearings in terms of load capacity, structure and performance.  To this end, rolling bearings need a variety of structures.  However, the most basic structure is composed of an inner ring, an outer ring, a rolling body and a cage -- often referred to as the four major pieces.

Bearing the instance

For sealed bearings, plus lubricant and sealing ring (or dust cover) - also known as six pieces.  Various bearing types are mostly named according to the name of the rolling body.  The roles of various parts in bearings are: for centripetal bearings, the inner ring is usually closely matched with the shaft, and operates with the shaft, and the outer ring is usually transitional with the bearing seat or mechanical shell hole, playing a supporting role.  However, in some cases, there is also an outer ring running, the inner ring fixed supporting role or the inner ring, the outer ring are running at the same time.

For thrust bearings, the bearing ring is closely matched with the shaft and moves together, and the bearing seat or mechanical shell hole into a transition match and supporting the bearing ring.  The rolling body (steel ball, roller or needle) in the bearing usually with the help of the cage evenly arranged between the two rings for rolling movement, its shape, size and number directly affect the bearing load capacity and performance.  The cage can not only evenly separate the rolling body, but also guide the rotation of the rolling body and improve the lubrication performance of the bearing.

There are many kinds of bearings and their functions are not the same, but the working principle of bearings is generally described above.
