Description

High-efficient radiating roller bearing

Technical Field

The utility model relates to the technical field of roller bearings, in particular to a roller bearing with efficient heat dissipation.

Background

A roller bearing is a common mechanical element consisting of an inner ring, an outer ring, rollers and a cage. Roller bearings reduce friction between the shaft and the bearing by rolling friction, thereby effecting rotational movement of the mechanical component. Roller bearings have a higher load carrying capacity and a lower coefficient of friction than other types of bearings. They are suitable for use in high-speed rotating and high-load operating environments such as machine tools, automotive engines, wind turbines, etc. In roller bearings, the shape and number of rollers can affect their load carrying capacity and friction performance. Common roller shapes are cylindrical, conical and tapered rollers. Cylindrical roller bearings are suitable for smaller radial loads and conical roller bearings are suitable for larger radial and axial loads.

However, the conventional inner roller bearing generates heat during high-speed operation, and the bearing may be damaged when the temperature of the bearing is too high, so that the service life of the bearing is affected.
