Developed on the basis of the sliding bearing of rolling bearing, its working principle is based on rolling friction instead of sliding friction, generally by two ring, a set of rolling elements and a cage of strong commonality, a high degree of standardization, seriation of mechanical components.
With different working conditions for various machinery, rolling bearing in the load capacity, structure, and puts forward various requirements in such aspects as the use of performance.
Therefore, needs to have all kinds of rolling bearing structure.
However, the most basic structure is composed of inner ring and outer ring, rolling element and cage.
The role of various parts in bearing are respectively: for radial bearings, inner ring and shaft tight fit, usually with working shaft, outer ring and bearing seat or mechanical shell usually blastholes transition fit, the supporting role.
However, in some cases, also have outer ring, inner ring fixed supporting role or inner ring and outer ring are running at the same time.
For the thrust bearing, and shaft tight said shaft and joined the sports circle, cooperate with or mechanical bearing shell blastholes transition said seat and a supporting role.
Rolling body (
Steel ball, roller, or needle)
Usually use within the bearing cage evenly arranged between the two ring rolling movement, it directly influences the shape, size and quantity of bearing load capacity and performance.
Cage outside roller can be evenly separated, also can guide roller rotating and improve internal bearing lubrication performance, and so on.
