Background technology
At present; The cylindrical of employed in the prior art Sai Kexin+permanent magnetism mixed magnetic circuit alternator rotor is a cup structure; Rotor promptly often adopt a cup that the star magnetic pole and the tubular magnetic pole of rotor are all covered, owing to need bear the centrifugal force that high speed rotating produced of tens thousand of commentaries on classics when work; Often bear the centrifugal force of whole rotor high-speed rotation through cup, therefore very high to rotor cap cup structure requirement of strength.Yet process because the cup of its rotor is a plurality of part assembly unit welding, therefore when making cup, all very strict to the manufacturing materials and the manufacturing process requirement of cup, cup processing is difficulty very.Add man-hour carrying out cup, often through method moulding such as vacuum diffusion welding, electron beam welding, hot investment castings, its cost of manufacture is expensive, scrappage is high, reliability is low.So just a series of problems such as existing in the prior art rotor passing rate of processing is low, cost of manufacture is high, dependability is low have been produced.Therefore existing alternator rotor structure still is not ideal enough.
Summary of the invention
The purpose of the utility model is: a kind of simple in structure, cost of manufacture is lower and functional reliability is higher high speed alternator rotor is provided, to overcome the deficiency of prior art.
The utility model is to constitute like this: a kind of high speed alternator rotor of utility model does; This rotor comprises and is provided with star magnetic pole that is used to install the rotor shaft for alternator axis hole and the tubular magnetic pole that is provided with magnetic pole projection end; On each magnetic pole tooth of star magnetic pole, all being provided with one is the magnetic conduction end of one with magnetic pole tooth; The top end face of magnetic conduction end is the arc surface shape, and the arc diameter of this arc surface is identical with the outside diameter of tubular magnetic pole; On each magnetic conduction end, all fixed a U-shaped at a distance from magnet, the groove of tubular magnetic pole magnetic pole projection end fixes respectively at U-shaped on magnet, and between each the magnetic pole projection of tubular magnetic pole and star magnetic pole, has all fixed a magnet steel.
Each magnetic conduction end is a V-shape perpendicular to the cross sectional shape of star magnetic pole axial line.
On the magnetic pole tooth rear end face of above-mentioned star magnetic pole, be connected with the back back-up ring through screw, on the magnetic pole tooth front end face of star magnetic pole, be connected with spill through screw before back-up ring.
The magnetic pole projection of the external cylindrical surface of back-up ring and tubular magnetic pole and U-shaped link together at a distance from magnet before the above-mentioned spill.
Back-up ring is the non-magnet_conductible material back-up ring with the back back-up ring before the above-mentioned spill.
Back-up ring preferably is non-magnetic stainless steel material back-up ring with the back back-up ring before the above-mentioned spill.
Owing to adopted technique scheme; The utility model has been discarded the cup structure that alternator rotor adopted in the prior art fully; The rotor structure of the utility model has been cancelled the cup on conventional Sai Kexin+permanent magnetism mixed magnetic circuit alternator rotor; The utility model is under the prerequisite that does not change magnetic structure; The star magnetic pole of the former inside of rotor is extended (promptly all producing a magnetic conduction end that connects as one with magnetic pole tooth on each magnetic pole tooth at the conventional spider magnetic pole) to the rotor cylindrical, and utilize the V font structure of magnetic conduction end on the star magnetic pole, the separated magnet of U-shaped that the star magnetic pole that links closely is outer; Simultaneously the star magnetic pole connects as one through back-up ring before the spill and tubular magnetic pole and the separated magnet of U-shaped again, connects overall structure closely thereby form one.The utility model has changed alternator rotor general cup structure at present; And the utility model is under the situation that does not change magnetic circuit; Connect through mechanical system; Make rotor organically become as a whole, the utility model has and has improved the reliability of rotor when high speed rotating effectively when reducing making rotor difficulty greatly.So, the utility model compared with prior art, the advantage that the utility model not only has is simple in structure, make easily, cost of manufacture is low, but also have rotor mechanical intensity height, long service life, advantage that functional reliability is high.
