Abstract

A permanent magnet eddy current coupling belongs to the field of magnetic transmission and particularly relates to the field of permanent magnet eddy current couplings. The permanent magnet eddy current coupling solves the problems that an existing permanent magnet eddy current coupling is small in torque transmission capacity and limited in installation. The permanent magnet eddy current couplingcomprises a conductor unit and a permanent magnet unit which are coaxially arranged, and an air gap is formed between the conductor unit and the permanent magnet unit; and each conductor unit comprises a conductor back iron disc and a conductor disc. The permanent magnet unit comprises a permanent magnet, a permanent magnet back iron disc and a permanent magnet mounting disc; the conductor disc is coaxially connected with the back iron disc, and the conductor disc is located at the air gap side; the permanent magnet mounting disc and the permanent magnet back iron disc are coaxially connected, and the permanent magnet mounting disc is located on the air gap side; the permanent magnets are arranged at equal intervals in the circumferential direction of the permanent magnet mounting disc; and the permanent magnets comprise an inner arc permanent magnet and an outer arc permanent magnet, the inner arc permanent magnet and the outer arc permanent magnet are both T-shaped, and the T-shapedhorizontal sections of the inner arc permanent magnet and the outer arc permanent magnet are close to the edge of the permanent magnet mounting disc. The permanent magnet eddy current coupling is suitable for being used as a coupling.

Description

technical field [0001] The invention belongs to the field of magnetic transmission, in particular to the field of permanent magnet eddy current couplings. Background technique [0002] As a connecting device in a mechanical system, the coupling has a wide range of applications. At present, the couplings used in the mechanical field are divided into mechanical couplings, hydraulic couplings and magnetic transmission couplings. The mechanical coupling transmits torque through mechanical connection, the additional force generated during operation is relatively large, and the ability to isolate vibration is relatively weak. The hydraulic coupling transmits torque through the interaction between fluids, the transmission efficiency is reduced, the service life is short, and the later maintenance workload is large. The magnetic transmission coupling uses the interaction between magnetic fields to transmit torque, which belongs to non-contact torque transmission. It has the charac...
