Abstract

The invention provides a manual speed-adjustment permanent-magnet coupler, and the coupler comprises a permanent-magnet coupler. The permanent-magnet coupler comprises a power part and a transmission part. The power part comprises a motor and a conductor column connected with a motor shaft. The transmission part comprises a transmission shaft, a magnet cylinder connected with the transmission shaft, and at least two permanent magnets disposed at an inner side of the magnet cylinder. There are gaps between the conductor column and the permanent magnets, and the distances, between adjacent permanent magnets, along the periphery of the magnet cylinder are equal. The coupler also comprises a speed-adjustment device which is disposed at the transmission part of the permanent-magnet coupler. The speed-adjustment device comprises a seat body, a supporting part in fixed connection with the transmission part, and a cylindrical adjustment rack which is fixedly connected with the supporting part through a fixed rod and disposed in a fixed groove on the seat body. A hand-operated handle is disposed at a side of the fixed groove, and is in adaptive connection with a cylindrical straight tooth part of the cylindrical adjustment rack. Through the design, the coupler can achieve the indirect adjustment of the rotating speed of the transmission part through the manual adjustment of the hand-operated handle, and is practical.

Description

technical field [0001] The invention relates to a coupler, in particular to a permanent magnet coupler with manual speed adjustment. Background technique [0002] The permanent magnet speed governor consists of three parts: conductor disk, magnet disk, motor and load. Among them, the conductor disk is installed on the motor, and the magnet disk is installed on the load (fan, water pump, etc.). There is no mechanical connection between the conductor disk and the magnet disk, and there is an air gap; permanent magnets are installed on the magnet disk. When the motor rotates, the conductor disc of the drive part rotates, and the conductor disc moves relative to the magnet, and an induced current is generated in the conductor disc, which is then converted into an induced magnetic field. The induced magnetic field interacts with the magnetic field generated by the original permanent magnet to drive the load to rotate, realizing The effect of torque transmission through the a...
