Abstract

The invention discloses a magnetic bearing and relates to the technical field of bearings. The magnetic bearing comprises a bearing body, a bearing lug, a first magnetic bearing body, a second magnetic bearing body, a ball bearing body and a sealing ring, the outer wall of the bearing body is welded to the outer wall of the bearing lug, and the inner wall of the bearing lug is fixedly provided with the first magnetic bearing body; the second magnetic bearing body is fixedly installed at the side, close to the first magnetic bearing body, of the inner wall of the bearing lug, the sealing ring is clamped to the outer wall of the first magnetic bearing body, and the inner wall of the bearing body is fixedly provided with the ball bearing body. According to the magnetic bearing, by arranging the magnetic bearing body, a magnetic coil is installed for generating magnetic force; by arranging a sensing coil, the rotation speed of the magnetic bearing body is adjusted; by arranging a sealing plate, dust is prevented from entering the magnetic bearing, and the generated magnetic force is also prevented from influencing other parts; by arranging a sensing joint, a sensor is conveniently connected for outputting a rotation speed signal of the magnetic bearing body; by arranging the bearing lug, the magnetic bearing is conveniently fixed; by arranging a first sealing valve, lubricating oilis conveniently injected into the magnetic bearing.

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...
