Embodiment Construction

[0015] The new type of reluctance clutch assembly figure 1 . Its shape and size are exactly the same as the current magnetic particle separator. (outer diameter Length 65) equally sets input gear at the front end, and its modulus is also the same. The installation interface size is exactly the same, use The circle and its end face are positioned, fastened with three M4 screws, and there are two terminal posts (not shown in the figure) protruding out for the electrical connection of the winding.

[0016] The reluctance clutch is essentially a special micro-motor. Because the magnetic force of the clutch does not realize the non-contact and frictionless clutch, it works stably, reliably and has a long life. The reluctance clutch of the present invention mainly comprises three parts:

[0017] 1) The input rotating rotor is called "active rotor". The rotation of the flight control motor is input into the clutch through the gear to form the rotation of the active rotor. The...

Abstract

A reluctance type minitype clutch comprises a driving rotor, a driven rotor and a stator. A shaft of the driven rotor is mounted in the center of the stator. The driving rotor is mounted outside the stator. The reluctance type minitype clutch is characterized in that a first working reluctance air gap exists between an embedded magnetizer in the driven rotor and a magnetizer located outside the driven rotor and located on the outer ring of the driving rotor, and a second working reluctance air gap exists between the embedded magnetizer of the driven rotor and a radiate toothed magnetic pole located in the inner ring of the driving rotor and located on the inner side of the driven rotor; one end on an outer shell of the driving rotor is sleeved with a gear. The reluctance type minitype clutch based on the electromagnetic principle and micromotor design, the four technical measures of double air gaps, comb tooth type longitudinal teeth, cast aluminum special structural design and fully increased conductivity are adopted. The load indexes and the time constant of the reluctance clutch are made to reach the level of a currently used magnetic powder clutch, and the reluctance clutch is completely identical with a currently applied clutch in boundary dimension and mounting mode; in this way, the reliability of flight control devices of an airplane is improved, and the service life of the flight control devices of the airplane is prolonged.

Description

technical field [0001] The invention belongs to the aircraft automatic flight control technology, and is a novel electromagnetic clutch-reluctance clutch, which is used in the executive mechanism of the flight control system of the aircraft. Background technique [0002] At present, in the flight control systems of some aircrafts in Russia and my country, the clutches used are magnetic powder clutches. Due to the friction and heat generation of magnetic powder during work, the magnetic properties will change (the magnetic permeability will decrease and the coercive force will increase), and the magnetic powder will agglomerate and agglomerate. What's more, the magnetic powder particles will wear and damage the rubber sealing ring, causing the particles to enter Bearings are stuck. Therefore, the operation of the magnetic powder clutch is unstable, and there are many faults and short life. At present, the production is based on screening and elimination before submission. I...
