Novel rolling bearing

Abstract

The invention discloses a novel rolling bearing. The novel rolling bearing comprises an inner ring, an outer ring and a retainer, the retainer is provided with a plurality of pockets used for containing rollers, the pockets are connected through beam bodies, and the novel rolling bearing is characterized in that the inner walls of the pockets are provided with open grooves, movable blocks are arranged in the open grooves, one ends of the movable blocks are fixedly connected with the inner walls of the open grooves, grease scraping cottons are arranged at the other ends of the movable blocks, the movable blocks are made of shape memory alloys, the movable blocks have a first form at the first temperature, the movable blocks have a second form at the second temperature, the movable blocks extend in the first form to enable the grease scraping cottons to be exposed out of the open grooves to make contact with the rollers in the pockets, and the movable blocks contract in the second form to enable the grease scraping cottons to retract into the open grooves. According to the novel rolling bearing, the phenomena of grease throwing and grease leakage in the bearing caused by excessive grease in the bearing are avoided, and the service life of the bearing is further ensured not to be reduced due to grease loss.

Description

technical field [0001] The invention relates to the technical field of bearings, in particular to a novel rolling bearing. Background technique [0002] Rolling bearing is a precision mechanical element that changes the sliding friction between the running shaft and the shaft seat into rolling friction, thereby reducing friction loss. Rolling bearings are generally composed of four parts: inner ring, outer ring, rolling body and cage. The function of the inner ring is to cooperate with the shaft and rotate together with the shaft; the function of the outer ring is to cooperate with the bearing seat to play a supporting role; Because the cage evenly distributes the rolling elements between the inner ring and the outer ring, its shape, size and quantity directly affect the performance and life of the rolling bearing; the cage can evenly distribute the rolling elements and guide the rolling elements to rotate for lubrication. Common rolling bearings are filled with grease to r...
