magnetic coupler

Abstract

The invention relates to a magnetic coupler, which comprises an engine seat, a case cover, a conductor rotor and a magnetic rotor, wherein the engine seat is fixed on the ground and is connected with the case cover in a horizontal middle open type structure; the engine seat, and an input shaft and an output shaft which are extended out of the case cover are arranged in a coupler; a needle roller bearing which is connected with the inner end of the output shaft is arranged at the inner end of the input shaft; the input shaft is connected with a conductor plate which is connected with the conductor rotor; the output shaft is connected with a permanent magnet trough plate which is connected with the magnetic rotor; and the permanent magnet trough plate is connected to a worm gear transmission mechanism through an angular contact bearing. In the invention, the magnetic coupler which can make the using performance of the coupler greatly improved and the service life of the coupler greatly prolonged and is convenient and easy to examine and repair is provided.

Description

technical field [0001] The invention relates to a transmission device, in particular to a magnetic coupling. Background technique [0002] The working principle of the magnetic coupler follows the Coulomb's law of magnetism, that is, two magnets separated by a certain distance, due to the magnetic field induction effect, they do not need any traditional mechanical components, and the power can be transferred from one magnet to the other through the coupling force of the magnets. A magnet that constitutes a non-contact torque transmission mechanism. [0003] The magnetic coupling is divided into two parts, the conductor rotor connected to the prime mover and the magnetic rotor connected to the load. The output torque is adjusted by adjusting the gap (air gap) between the conductor rotor and the magnetic rotor, thereby realizing speed regulation. [0004] The above-mentioned magnetic coupler has the following defects: 1) After the magnetic coupler works for a long time, the r...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned magnetic coupler has the following defects: 1) After the magnetic coupler works for a long time, the rotor is often damaged due to various reasons, and the rotor is prone to damage. Move, take out the rotor and then put the new rotor in. Due to the movement of the machine base, the alignment needs to be re-calibrated, which greatly prolongs the maintenance and downtime time; 2) The existing output shaft structure is an extended beam, and its outer end passes through The bearing is connected to the stator, and the inner end is suspended in the air. This structure results in poor rigidity of the extension shaft, which is prone to bending or even breaking during use, which affects the performance of the coupler and poses a safety hazard; 3) During the working process, the conductor The axial force generated between the rotor and the magnetic rotor is relatively large. If it cannot be eliminated in time and effectively, it will bring a heavy burden to the output shaft and input shaft, and its service life will be greatly shortened.
