Abstract

The invention relates to a non-contact type speed-adjustable electromagnetic coupler which comprises an outer rotor assembly, an inner rotor assembly and a conducting assembly, wherein the inner rotor assembly and the outer rotor assembly are mutually and electromagnetically coupled in a power-on state; the conducting assembly comprises three lead slots arranged on the side face of an inner rotor shaft, three leads respectively arranged in the lead slots, three conducting rings fixed on the side face of the rear end part of the inner rotor shaft and a three-phase static electric brush respectively in fitting contact with the three conducting rings; one end of each lead is respectively connected with an inner rotor armature winding, while the other ends are respectively connected with the three conducting rings; and the three-phase static electric brush is respectively connected with a three-phase alternating current power supply. The invention solves the technical problem that the speed of the traditional hydraulic coupler cannot be adjusted. The non-contact type speed-adjustable electromagnetic coupler can be used for realizing mechanical energy transmission, meanwhile, the speed can be adjusted, thus the non-contact type speed-adjustable electromagnetic coupler can be used for replacing the traditional coupler in a transmission system to realize the non-contact connection of the mechanical transmission system.

Description

technical field [0001] The invention relates to a coupler, in particular to an adjustable-speed electromagnetic coupler. technical background [0002] In the mechanical transmission system, the hydraulic coupling is used to transmit mechanical energy, which can avoid rigid connection and eliminate input torque fluctuations. However, the hydraulic coupling has the following problems: when the input speed is constant, the output speed cannot be adjusted; or when the input speed changes, the output speed cannot be kept constant. So its application range is limited. Contents of the invention [0003] In order to solve the technical problem that the existing hydraulic coupler cannot adjust the speed, the present invention proposes a non-contact adjustable speed electromagnetic coupler, which can realize the transmission of mechanical energy and can adjust the speed at the same time. [0004] Technical solution of the present invention is: [0005] A non-contact adjustable sp...
