Abstract

The invention relates to a grouping-cascade-type permanent magnet coupling . The coupling is mainly formed by a permanent magnet disc and a conductor disc. The conductor disc is formed by different quantities of conductor disc assemblies and is installed on a motor shaft. The permanent magnet disc is formed by different quantities of permanent magnet disc assemblies and is installed on a load shaft. The permanent magnet disc and the permanent magnet disc are not contacted and realize a magnetic force coupling transmission torque through opposite rotation. Different assembly quantities can form the permanent magnet couplings with different power. The plurality of assemblies make eddy current loss points disperse so that a purpose of high-efficient heat dissipation is reached.

Description

technical field [0001] The invention relates to the technical field of motor flexible coupling, in particular to a grouped cascade permanent magnet coupling. Background technique [0002] Coupling connections, gear connections, belt connections, etc. of mechanical transmission are all hard connections, and hydraulic couplings are a flexible connection method. The hard connection has problems such as large starting torque, high centering requirements, and mutual transmission of vibrations affecting the service life of the equipment. Although the hydraulic coupling is a flexible connection, it has problems such as low efficiency and complicated maintenance. [0003] Permanent magnetic coupling is a new type of coupling device, which has the advantages of flexible transmission, effective vibration isolation, long life cycle, low failure rate, simple maintenance, and low environmental requirements. However, due to the eddy current loss caused by the speed difference between the...
