Rolling bearing of motor

Abstract

The invention discloses a rolling bearing of a motor, and relates to the technical field of rolling bearings. The rolling bearing of the motor comprises an outer ring. Steel balls are arranged on theinner side of the outer ring. An oil outlet is formed in the inner wall of the outer ring. An oil storage groove is formed in the outer ring. Third grooves are formed in the inner wall of the outer ring and are located on the two sides of the oil outlet. A retainer is arranged on the outer walls of the steel balls. According to the rolling bearing of the motor, outer ring dust-proof strips, innerring dust-proof strips and a protective screen are arranged, the outer ring dust-proof strips on the outer ring are clamped through a first fixing ring, the inner ring dust-proof strips on the inner ring are clamped through a second fixing ring, the outer ring dust-proof strips overlap with the inner ring dust-proof strips, and dust can adhere to grease smeared on the outer ring dust-proof stripsand the inner ring dust-proof strips so as to be blocked; and protective screen on the inner sides of the inner ring dust-proof strips is clamped on the outer ring and the inner ring through an outerfixing ring and an inner fixing ring to block large-granularity foreign matter, so that particles are prevented from entering the bearing, and the problem that the operating precision of the bearing is reduced due to invasion of outside particles is effectively solved.

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
