Powder metallurgy bearing for supporting motor rotor in a motor

Abstract

The invention discloses a powder metallurgical bearing for supporting a motor rotor in a motor, and relates to the technical field of motors. An inner ring is composed of two inner arc-shaped rings, the top ends of the two inner arc-shaped rings are connected and fixed in a clamping mode, the bottom ends of the two inner arc-shaped rings are movably hinged, an outer ring is composed of two outer arc-shaped rings, the top ends of the two outer arc-shaped rings are connected and fixed in a clamping mode, the bottom ends of the two outer arc-shaped rings are movably hinged, and the front face ofthe outer ring is provided with convex ends. According to the powder metallurgical bearing for supporting the motor rotor in the motor, the mode of two-part movable installation is adopted, the bearing is conveniently disassembled, the problem of trouble bearing disassembly is solved, replacement is convenient, later maintenance and preservation are facilitated, the labor intensity is reduced, theaxial preload of the rotor bearing is adjusted by elasticity of the convex ends, the drawback of overweight axial overload is avoided, the badness of axial movement is eliminated, meanwhile the noiseproduced by vibration is reduced, and self-lubrication is realized.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a powder metallurgy bearing for supporting a motor rotor in a motor. Background technique [0002] The motor rotor is the rotating part in the motor. The motor is composed of two parts: the rotor and the stator. It is used to realize the conversion device of electrical energy and mechanical energy and mechanical energy and electrical energy. The motor rotor is divided into the motor rotor and the generator rotor. The motor rotor is divided into There are two types of inner rotor rotation and outer rotor rotation. The inner rotor rotation mode is that the core body in the middle of the motor is a rotating body, which outputs torque or receives energy. The outer rotor rotation mode uses the outer body of the motor as a rotating body. Different methods are convenient. Applications in various occasions Bearing is an important part of contemporary mechanical equipment. Its main functio...
