Description
Technical Field
The utility model relates to the technical field of bearings, in particular to a rolling bearing with an outer ring provided with a special fixing groove.
Background
Rolling bearings are a precision mechanical element that changes sliding friction between an operating shaft and a shaft seat into rolling friction, thereby reducing friction losses. The rolling bearing generally comprises four parts, namely an inner ring, an outer ring, rolling bodies and a retainer, wherein the inner ring is matched with the shaft and rotates together with the shaft, the outer ring is matched with the bearing seat to play a supporting role, the rolling bodies are uniformly distributed between the inner ring and the outer ring by means of the retainer, the shape, the size and the number of the rolling bodies directly influence the service performance and the service life of the rolling bearing, the retainer can uniformly distribute the rolling bodies, and the rolling bodies are guided to rotate to play a lubricating role.
However, the existing bearing outer ring and the bearing seat are often in interference fit or transition fit so as to keep the tight connection between the two. When the rotation speed of the shaft is lower, the friction force of the matching surfaces of the two can be utilized to prevent rotation, but the friction force between the two is smaller than the relative movement trend (for example, when the rotation speed of the shaft is very high or the outer diameter of the outer ring is very small), if the outer ring is only in fit with the interference, the outer ring rotates along with the shaft, so that abrasion is easily caused between the outer ring and the bearing seat of the bearing, and the service effect and the service life of the bearing are affected. In summary, the conventional rolling bearing has the following problems:
When the rotation speed of the shaft is lower, the friction force of the matching surfaces of the two can be utilized to prevent rotation, but when the friction force between the two is smaller than the relative motion trend, the outer ring rotates along with the shaft only by the interference fit, and the abrasion between the bearing outer ring and the bearing seat is easy to occur.
