A motor rolling bearing

Abstract

The invention discloses a motor rolling bearing, which relates to the technical field of rolling bearings, and comprises an outer ring. Steel balls are arranged on the inner side of the outer ring, an oil outlet hole is arranged on the inner wall of the outer ring, and an oil storage tank is arranged inside the outer ring. In addition, the inner wall of the outer ring is provided with a third groove on both sides of the oil outlet hole, and the outer wall of the steel ball is provided with a cage. In the present invention, through the provided outer ring dust-proof strip, inner ring dust-proof strip and protective net, the outer ring dust-proof strip on the outer ring is engaged by the first fixing ring, and the inner ring dust-proof strip on the inner ring is fixed by the second fixed ring. The dust-proof strips of the outer ring and the dust-proof strips of the inner ring overlap, and the grease applied on them makes the dust adhere, thus achieving the blocking of dust. The protective net inside the dust-proof strip of the inner ring passes through the outer fixing ring and the inner fixing The ring is snapped on the outer ring and the inner ring to block the foreign matter with large particles and prevent the particles from entering the inside of the bearing, which effectively solves the problem of the reduction of the running accuracy of the bearing caused by the intrusion of external dust particles.

Description

technical field [0001] The invention relates to the technical field of rolling bearings, in particular to a rolling bearing for a motor. 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 inner rings, outer rings, rolling elements and cages. The function of the 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 and play a supporting role; the rolling elements are evenly distributed between the inner ring and the outer ring by means of the cage, and its The 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.

Problems solved by technology

[0004] The purpose of the present invention is to provide a motor to solve the problems that the running precision of the bearing is reduced due to the intrusion of dust particles from the outside, the vibration and noise of the bearing are sharply increased due to the lack of grease in the bearing work, and the cracks and fractures of the bearing parts are caused by severe overload work. rolling bearing
