Compound speed regulation shaft-type magnetic coupling

A magnetic coupling and coupling technology, which is applied in the field of magnetic couplings and compound speed-adjustable shaft magnetic couplings, can solve the problem of low transmission efficiency of adjustable shaft magnetic couplings and common shaft couplings. The speed of the magnetic coupling cannot be adjusted, and the adjustable range of the speed is small, so as to achieve good application prospects, improve energy utilization, and avoid high neutral requirements.

Abstract

The invention relates to a compound speed regulation shaft-type magnetic coupling comprising a driving shaft, an inner rotor mechanism connected to the driving shaft and used for adjusting the air gap thickness of the coupling, an outer rotor mechanism disposed opposite to the inner rotor mechanism and used for adjusting the air gap length of the coupling, and a driven shaft in transmission connection to the outer rotor mechanism. The axis of the inner rotor mechanism and the axis of the outer rotor mechanism coincide with each other. Compared with the prior art, the compound speed regulation shaft-type magnetic coupling is simple and compact in structure, safe and stable, and can controllably adjust the output speed, is high in transmission torque, solves problems that a common shaft-type magnetic coupling is low in transmission power and not adjustable in speed, and a conventional adjustable shaft-type magnetic coupling is small in speed adjustable range and low in speed accuracy, and has a very good application prospect.

Description

technical field [0001] The invention belongs to the technical field of mechanical transmission magnetic speed regulation, and relates to a magnetic coupling, in particular to a composite speed regulation shaft type magnetic coupling. Background technique [0002] The speed-regulating magnetic coupling is a typical device of permanent magnet speed-regulating technology. By adjusting the air-gap magnetic field generated by the permanent magnets, the non-contact variable torque transmission between two pairs of permanent magnets is realized, thereby realizing adjustable The output speed avoids the problems of traditional couplings such as high neutral requirements, vibration transmission, non-adjustable speed, and bearing wear. It has inherent characteristics such as non-contact, no noise, no need for lubrication and cleaning, and has soft start and automatic overload. The advantage of protection has a good application prospect in the fields of petroleum, chemical industry, min...
