Description

Technical Field

[0001] The utility model relates to the technical field of cable reels, in particular to a magnetic coupling type cable reel. Background Art

[0002] Cable reels, also known as cable drums or cable reels, have replaced busbars due to their compact installation space, ease of maintenance, reliability, and low cost. They have become the mainstream solution for power transmission in mobile equipment and are widely used in lifting equipment and bulk material transport equipment. Currently, hysteresis cable reels are commonly used in China. Hysteresis cable reels consist of a motor, a reducer, a reel, and a magnetic coupling. The magnetic coupling, also known as a magnetic coupling, is a permanent magnet transmission device. It primarily consists of a conductor rotor and a permanent magnet rotor. The conductor rotor is connected to the motor shaft, and the permanent magnet rotor is connected to the working machine. An air gap exists between the conductor rotor and the permanent magnet rotor. Based on permanent magnet eddy current transmission technology, non-contact flexible transmission is achieved.

[0003] For example, a disc-type magnetic coupler for a cable reel and its cable reel transmission device, with publication number CN220744921U, includes an input end connected to the output shaft of a motor, a conductor disc assembly connected to the input end, a magnetic disk assembly arranged between the conductor disc assemblies, and an output end connected to the magnetic disk assembly, and the output end is used to connect to the cable reel. The conductor disc assembly includes a first conductor disc and a second conductor disc arranged on both sides of the magnetic disk assembly, and the magnetic disk assemblies are respectively separated from the first conductor disc and the second conductor disc by air gaps. A plurality of grooves are provided on the end surfaces of the opposite sides of the first conductor disc and the second conductor disc at intervals along the circumference thereof. By providing grooves on the opposite sides of the first conductor disc and the second conductor disc, and by providing grooves on the conductor discs, the magnetic coupler can stop the cable reel from rotating in a power-off state, and can also prevent the cable from collapsing.
