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

The reluctance type micro-clutch includes a driving rotor, a driven rotor and a stator. The shaft of the driven rotor is installed in the center of the stator, and the active rotor is installed outside the stator. And there is a first working reluctance air gap between the magnet conductors located in the outer ring of the active rotor, and there is a second working reluctance air gap between the embedded magnet conductors of the driven rotor and the radial toothed magnetic poles located in the inner ring of the active rotor. A magnetic resistance air gap; one end of the active rotor casing is sleeved with a gear. Starting from the electromagnetic principle and the ingenious design of the micro-motor, the present invention adopts four technical measures including double air gaps, comb-like longitudinal teeth, special structure design of cast aluminum and fully increasing the conductance. Make the load index and time constant of the magnetic reluctance clutch to the level of the magnetic powder clutch in use, and the magnetic reluctance clutch with the exact same size and installation method as the clutch being installed in the field, in order to improve the reliability and reliability of the aircraft flight control equipment. life.

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...
