Description

Long-life bearing

Technical Field

The utility model relates to the field of bearings, in particular to a long-service-life bearing.

Background

A rolling bearing (rolling bearing) is a precise mechanical element that changes sliding friction between a running shaft and a shaft seat into rolling friction, thereby reducing friction loss. The rolling bearing generally comprises four parts, namely an inner ring, an outer ring, a rolling body and a retainer, wherein the inner ring is used for being matched with a shaft and rotating 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 virtue of the retainer, and the shape, size and number of the rolling bodies directly influence the service performance and service life of the rolling bearing; the retainer can uniformly distribute the rolling bodies, guide the rolling bodies to rotate to play a lubricating role, simultaneously support the rotating shaft and parts on the shaft, and keep the normal working position and the rotating precision of the shaft. Compared with a sliding bearing, the rolling bearing has larger radial dimension, poorer vibration damping capability, low service life at high speed and larger sound.

But traditional bearing life-span is not high, and under the operational environment of high strength, the pressure of ball and contact surface can sharply increase, and then directly influences the intensity of bearing, and the cracked condition of bearing appears even can appear, and the bearing also can produce a large amount of heats in-process at a high speed simultaneously, also can influence the performance of bearing.

An effective solution to the problems in the related art has not been proposed yet.
