Novel magnetic-resistance-type electromagnetic clutch

Abstract

The invention provides a novel magnetic-resistance-type electromagnetic clutch. The clutch possesses a stator, a winding and a rotor. The rotor comprises an active rotor and a driven rotor. The stator is supported on an output shaft of the driven rotor through a bearing I and a rotor disk on the driven rotor is inserted into an annular space of an active rotor disk. The active rotor is supported on an outer circumference of the stator through a bearing II and a bearing III and the winding sleeving the stator is placed between the stator and the active rotor. The annular space is formed by upper jaw teeth and lower jaw teeth, the upper jaw teeth and the lower jaw teeth are provided with a same number of teeth and the teeth correspond to each other. The teeth, which are embedded into the rotor disc, correspond to the upper jaw teeth and the lower jaw teeth, and are inserted into the annular space. In the invention, a problem that magnetic performance of a magnetic powder type clutch becomes poor due to mutual friction and aging so that condensation, agglomeration or magnetic powder leakage are generated and a bearing is stuck and other problems are solved, the structure is simple, a service life is long, reliability and safety of flight are increased, and a combined torque and a combined speed are greatly improved.

Description

technical field [0001] The invention belongs to the technical field of aircraft automatic control, and in particular relates to a novel reluctance type electromagnetic clutch, which is used in an executive mechanism of an airborne aircraft automatic control system. Background technique [0002] At present, in the flight control systems of some aircrafts in Russia and my country, small magnetic powder clutches are usually used. Because the magnetic powder of the magnetic powder clutch enters the running bearing, the bearing will be stuck, and the magnetic powder will rub against each other in the clutch. can deteriorate, lead to coagulation, agglomeration, cause failure, and greatly reduce the service life; and (ZL201210078990.1) patent, the reluctance eddy current electromagnetic clutch is a special micro-motor in essence, and the reluctance eddy current electromagnetic clutch is a single breath Reluctance, low motor coefficient, large volume and small torque, in order to impr...
