Description

Magnetic coupler Technical Field The utility model relates to the technical field of magnetic couplers, in particular to a magnetic coupler. Background The magnetic coupler is also called as a magnetic coupler and a permanent magnet transmission device, and mainly comprises three parts, namely a copper rotor, a permanent magnet rotor and a controller, wherein the copper rotor is connected with a motor shaft in general, the permanent magnet rotor is connected with a shaft of a working machine, an air gap is formed between the copper rotor and the permanent magnet rotor and is called as an air gap, and no mechanical connection for transmitting torque is formed, so that soft magnetic connection is formed between the motor and the working machine, and the change of the torque and the rotating speed of the shaft of the working machine is realized by adjusting the air gap. At present, in the prior art, the use of magnetic force coupler mainly starts the guard action, prevents that drive part from transshipping, protects drive part, because there is certain clearance in magnetic force coupler's drive end and driven end, leads to magnetic force coupler in the course of the work, and dust in the air easily enters into between magnetic force coupler's the drive end and the driven end, influences magnetic force coupler's work, in view of this, proposes a magnetic force coupler. Disclosure of utility model The present utility model is directed to a magnetic coupler, which solves the above-mentioned problems. In order to achieve the above object, the magnetic coupler provided by the utility model comprises a first shaft and a second shaft, wherein a first sleeve body is fixedly arranged on the first shaft through a bolt, a second sleeve body is fixedly arranged on the second shaft through a bolt, permanent magnets are respectively arranged in the first sleeve body and the second sleeve body, a protection assembly is arranged outside the first sleeve body, and the protection assembly comprises: the first protective shell is detachably connected with the second protective shell; The first protective shell and the second protective shell are respectively provided with a groove, a screw is hinged in the first protective shell, and the screw is in threaded connection with a nut; And the limiting ring is detachably connected to one end of the screw, far away from the first protective shell, of the screw through the bolt, and can limit the nut through the use of the limiting ring so as to prevent the nut from falling off.
