Abstract

The invention discloses a magnetic bearing, which relates to the technical field of bearings, and comprises a body, a bearing lug, a first magnetic bearing, a second magnetic bearing, a ball bearing and a sealing ring. A first magnetic bearing is fixedly installed on the inner wall of the bearing lug, a second magnetic bearing is fixedly installed on the side of the inner wall of the bearing lug close to the first magnetic bearing, the outer wall of the first magnetic bearing is clamped with a sealing ring, and the A ball bearing is fixedly mounted on the inner wall of the body. In the magnetic bearing, the magnetic bearing body is arranged to generate magnetic force for installing the magnetic coil, and the sensing coil is arranged to control the rotation speed of the magnetic bearing body. The sensor joint is provided to facilitate the connection of the sensor to output the rotational speed signal of the magnetic bearing body, the bearing lug is provided to facilitate the fixing of the magnetic bearing, and the first sealing valve is provided to facilitate the injection of lubricating oil.

Description

technical field [0001] The invention relates to the technical field of bearings, in particular to a magnetic bearing. Background technique [0002] Magnetic suspension bearings have excellent characteristics such as no friction, no wear, no need for seal lubrication, high speed, high precision, long life and low maintenance cost, which can effectively solve the bearing support problem of high-speed motors. According to whether the levitation force can be actively controlled, magnetic bearings can generally be divided into two types: passive type and active type. Active magnetic bearings can realize the suspension of the rotating shaft by controlling the electromagnetic force between the stator and the rotor, and are widely used in the field of high-speed motors. According to the method of establishing the bias magnetic field, active magnetic bearings can be divided into electromagnetic type and hybrid type. The bias flux of hybrid magnetic bearings is generated by permanen...
