Novel magnetic-resistance-type electromagnetic clutch

Abstract

A new type of reluctance electromagnetic clutch is provided, which has a stator, a winding and a rotor. The rotor includes a driving rotor and a driven rotor. The stator is supported on the output shaft of the driven rotor through a bearing I and the rotor on the driven rotor is The disc is inserted into the annular space on the active rotor disc. The active rotor is supported on the outer circumference of the stator through bearings II and III, and the windings sleeved on the stator are placed between the stator and the active rotor. The annular space is formed by the upper jaw Teeth and mandibular teeth are formed, and the maxillary teeth and mandibular teeth are provided with the same number of teeth corresponding to each other. The rotor disk is embedded with teeth corresponding to the maxillary teeth and mandibular teeth and inserted into the annular space. The invention solves the problems of the magnetic powder clutches due to mutual friction and aging, which lead to deterioration of magnetic properties, resulting in condensation, agglomeration, or magnetic powder leakage, causing the bearing to be stuck, etc., has a simple structure, long service life, and improves the reliability and safety of flight. , The combined torque and 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...
