Description
Affiliated technical field
The present invention relates to a kind of gas compressor and aircraft engine of can be eccentric shaft magnetic quake-proof suspension dynamical system in power and support anti-is provided, especially zero wearing and tearing of the tool in the time of can realizing gas compression, can prevent simultaneously that the axis deadweight from causing off-centre, belongs to magnetic suspension power technology field.
Background technology
The order face, its power section of known air compressor and aircraft engine and gas compression part mostly rely on ball bearing to realize supporting, so limited the rotating speed of aircraft engine, compressor and air blast.The high-speed magnetic levitation air blast of Shanghai Communications University, Xi'an research does not have shock resistance, and the magnetic levitaion motor of Nanjing Normal University's research is not considered the factor of rotor deadweight, and is seriously eccentric in the time of can causing the rotor rotation.
Summary of the invention
Rely on ball bearing to realize supporting in order to overcome existing gas compression dynamical system, and magnetic levitation technology can not antidetonation and the axis deadweight cause eccentric problem, the invention provides a kind of can be gas compressing apparatus provide the electric power of power anti-in eccentric shaft magnetic quake-proof suspension dynamical system.This system substitutes the mechanical force of mechanical bearing with magnetic force, air compressor and aircraft engine is carried out radial and axial fixing, utilizes a kind of mechanical bearing and axle sleeve of not contacting to realize spacing to rotor again.Thereby reach the rotation that both can realize full magnetic suspension, can realize the not eccentric and mechanical powerful antidetonation of axis again, the purpose of being convenient to transport for long-distance.
The technical scheme that problem adopted that the principle of the invention solves is: when being used for aircraft engine, can adopt axle center vertical-horizontal direction to place.Air enters by top, and discharge the bottom, and motor provides kinetic energy, and wherein the stationary part on the axis is a coil windings.The both sides of motor are equipped with two pairs respectively and are used for radially fixing permanent-magnetic clamp (if horizontal positioned, the magnetic field intensity that is used for support magnet below should be greater than the top magnetic field intensity that is used for fixing magnet).Radially two pairs of fixing permanent magnet outside installations are used for the mechanical bearing of antidetonation and do not contact axle sleeve, and the front portion of engine also is equipped with a pair of identical antishock device.Its pivotable parts all is fixed on rotor and puts.The fan group is installed in outside the rotor cover, the outward flange of going up next group fan is equipped with the belt permanent magnet that is used for axial support, form mutually the state of pushing tow up and down with the permanent-magnetic clamp that is installed in the engine housing inboard, following permanent-magnetic clamp magnetic field intensity is greater than the magnetic field intensity of top permanent-magnetic clamp.After engine rotation, the gas reaction force promotes engine and moves upward, the displacement forward of rotor this moment, following electromagnet and the distance between the magnets of stator can be dwindled, magnetic field tension force will increase like this, and oppositely distance meeting increase between the magnet, magnetic field tension force will reduce.The reaction force of air will be transmitted on the motor stator like this, promotes engine and advances.
Radial and axial spacing between antidetonation mechanical bearing and the axle sleeve is less than the spacing between every pair of levitated magnet and motor rotor and the stator.Can prevent from like this between the magnet to produce collision, avoid that damaged in collision causes shutting down between the high fragility magnet.
Another technical scheme that problem adopted that the principle of the invention solves is: when being used for gas compression, adopt axle center vertical-horizontal direction to place equally, gas enters from side opening, discharges from another side opening.This moment, the axis of compressor was a rotor, and the permanent magnet of motor is installed on the axis, and coil windings is installed on the stator.Main carrying magnetic suspension magnet ring is installed on the stator, with epitrochanterian support magnet ring be a pair of, form magnetic suspension.In the middle of compressor was installed in, the relative magnet ring of a pair of polarity was installed on the top of compressor, rotor is carried out axial suspension fix.Between the stator and rotor on the both sides of motor and compressor top, be separately installed with many magnet rings relative to polarity, be used for axial magnetic.It is middle that axis is suspended in.When external force surpassed magnetic field tension force, Antishocking bearing will bump against with stop collar.So can not bump against between the magnet.An end of axis can also design to transport and stablize bolt in addition, only uses when transportation.
The invention has the beneficial effects as follows, realized the anti-middle axle offset full magnetic suspension running of electric power aircraft engine, compressor or air blast under the low-cost state, and had good shock resistance.This technology can guarantee the stable of product operation.
This system's accessory can also repack anti-middle axle offset magnetic levitaion motor and permanent magnetic quake-proof suspension bearing in addition.
