Description

Technical Field

[0001] The utility model relates to the field of permanent magnet couplings, in particular to a structure of a cylindrical turntable permanent magnet coupling. Background Technique

[0002] The permanent magnet coupling, also known as the magnetic coupling and the permanent magnet drive device, mainly consists of three parts: a copper rotor, a permanent magnet rotor, and a controller. Generally, the copper rotor is connected to the motor shaft, and the permanent magnet rotor is connected to the shaft of the working machine. There is an air gap between the copper rotor and the permanent magnet rotor, and there is no mechanical connection for transmitting torque, which can realize a transmission method without mechanical connection between the motor and the load. Its working principle is that when there is relative movement between the two, the conductor assembly cuts the magnetic force lines, generating eddy currents in the conductor. The eddy currents then generate a reactive magnetic field, which interacts with the magnetic field generated by the permanent magnet, thereby realizing the torque transmission between the two.

[0003] Chinese Patent with the publication number CN220775620U discloses a cylindrical turntable permanent magnet coupling, including a sealed cylinder. The sealed cylinder is formed by splicing two symmetrical semi-cylinders. The middle parts of the two semi-cylinders on the side away from each other are rotatably connected by a sealed rotating shaft. One end of each of the two rotating shafts located inside the sealed cylinder is respectively fixed with a copper turntable and a permanent magnet turntable. The copper turntable and the permanent magnet turntable are inserted into each other and do not contact each other. One end of the rotating shaft connected to the copper turntable located outside the sealed cylinder is fixedly connected to the motor shaft. However, for the cylindrical turntable permanent magnet coupling in the above patent, after long-term operation, magnetic chips will be generated between the copper turntable and the permanent magnet turntable, which is convenient for cleaning the magnetic chips, increases the friction between the copper turntable and the permanent magnet turntable, and reduces the efficiency of torque transmission.
