Abstract
The utility model relates to a fly wheel rotor for intermediate frequency permanent magnet synchronous fly wheel generators. The fly wheel rotor for intermediate frequency permanent magnet synchronous fly wheel generators is characterized in that a supporting ring and at least ten magnets matched with the supporting ring are arranged in the rotor body. When the fly wheel rotor for intermediate frequency permanent magnet synchronous fly wheel generators is used, the claw of the supporting ring of the utility model is in a dovetail type, and the magnets firmly imbedded on the supporting ring of the inner wall of the fly wheel housing form a radial anti-shedding structure with the supporting ring. Under the dovetail type clamping function of the supporting ring and the cover ring, the magnets form an anti-shedding structure along an axial direction. No magnet shedding phenomenon occurs in the experiment of overspeed 1. 2 rated rotary speed and the experiment of strong collision. The dynamic balance structure controls the amount of unbalance within a small range, and the balance accuracy can reach over G 0. 4.
Description
Technical field:
The utility model relates to the technical field of flywheel rotor, specifically is used for the flywheel rotor of intermediate frequency permanent-magnet synchronous fly wheel generator, especially dynamic balancing structure and the magnet steel locking mechanism in the flywheel rotor.
Background technology:
Present traditional fly wheel generator, as magnetic motor for motorcycle, for satisfying self-excited oscillation and the magnet slip-off preventing problem that flywheel runs up, adopt following two kinds of methods usually:
A) solution of the self-excited oscillation that runs up of flywheel
Bell housing adopts minimum amount of unbalance screening technique, promptly often adopts inherent structure and manufacture level when the dynamic balancing of bell housing part, decides the whether qualified of flywheel part balance mass by the uneven limit value of minimum.When bell housing has the igniting boss, then adopt 180 degree positions to remove the eccentric throw problem that the material method remedies boss.Magnet adopts the screening technique of weighing to control amount of unbalance.Like this, behind bell housing and the synthetic flywheel rotor of group of magnets, its minimum amount of unbalance is intrinsic amount of unbalance, can't reduce or eliminate.This employing bell housing and magnet part and flywheel rotor parts amount of unbalance screening control method, easily cause the number of scrapping of product, and still have the existence of amount of unbalance in theory, especially in high-revolving portable power source, can't reach the performance of low vibration low noise.
B) solution of magnet slip-off preventing
Magnet and flywheel are fixing to be adopted with adhesive securement or magnet and flywheel is fixing in aggregates with non-magnet_conductible material coating mode on the magnet internal diameter.But only adopt the adhesive securement method can not guarantee the flywheel rotor impact resistance, and the non-magnet_conductible material coating easily causes power generator air gap to increase, performance reduces and the technology cost increases.
Summary of the invention:
The purpose of this utility model is to provide dynamic balancing structure and the magnet steel locking mechanism in a kind of improved flywheel rotor, and it can overcome the fixing unstable some shortcomings of flywheel rotor internal part imbalance, magnet and flywheel in the prior art.
To achieve these goals, the technical solution of the utility model is: the flywheel rotor that is used for intermediate frequency permanent-magnet synchronous fly wheel generator, it mainly comprises rotor block, is located at the middle axis hole of rotor block and is located at axis hole through hole on every side, it is characterized in that: be provided with a support ring in the rotor block, and at least ten blocks of magnet that match with support ring.
Pawl during use on the support ring of the present utility model is a dovetail type, and magnet is embedded securely on the support ring of bell housing inwall, forms radially anti-drop structure with support ring.Under the dovetail type clamping action of support ring and bezel ring,, magnet is axially also forming anti-drop structure, under test of hypervelocity 1.2 rated speeds and strong collision test the magnet obscission does not take place.This dynamic balancing structure is controlled at amount of unbalance in the very little scope, and balance quality can reach more than the G0.4.

Embodiment:
The utility model will be further described below in conjunction with drawings and Examples.
The utility model mainly comprises rotor block 1, be located at the middle axis hole 2 of rotor block and be located at axis hole through hole 3 on every side, its difference with the prior art is: be provided with a support ring 4 in the rotor block, and at least ten blocks of magnet that match with support ring 5, magnet is to adopt powder metallurgy technology mostly, by the mould sinter molding, magnet is down antiparallelogram, and the inwall that has certain radian and rotor block fits, on support ring, be evenly equipped with at least ten support columns 6, be provided with a magnet between per two support columns, the support column number is the flywheel magnet number of poles, the interior circular arc of support column is greater than external arc, be dovetail type, match with the shape of magnet, support column can be rounded, square or other well-regulated shape, support column inside is provided with a cavity 7, be provided with balance weight 8 in the cavity, support ring is provided with the bezel ring, that matches 9 with support ring.
In force, under the prerequisite that does not influence support ring intensity, the cavity cross section of support column is designed to maximum, several small cylinders that evenly distribute on support ring circumference connecting ring position are used for fixing with the circumference of bell housing.Earlier the plastic support ring is positioned the bell housing inwall by small cylinder, small cylinder is riveted on the bell housing inwall, magnet is bonded in the groove of claw type plastic support ring with bonding agent with melt process.On dynamic balancing machine, detect the amount of unbalance of flywheel rotor then.Utilize the resolution of vectors method, balance weight is put into the support column cavity cover the vinyl cover ring.
Because the support column on the plastic support ring is a dovetail type, magnet is embedded securely at the bell housing inwall, forms radially anti-drop structure.Under the dovetail type clamping action of plastic support ring and bezel ring,, magnet is axially also forming anti-drop structure, under test of hypervelocity 1.2 rated speeds and strong collision test the magnet obscission does not take place.Thereby amount of unbalance is controlled in the very little scope, and balance quality can reach more than the G0.4.
The utility model is a kind of structural design that embedded dynamic balancing heavy structure and magnet locking mechanism are combined.Can be widely used in branch location, dovetail lockings such as magnet, make full use of the space between each magnet, not only can be used as dynamic balancing and increase the weight of the locus, also can be used as dynamic balancing and go to heavy space, is that all permanent-magnetic outer rotor structures are in a kind of method of considering that balance combines with the magnet immobile phase.
