Abstract
The utility model discloses a dynamo magneto rotor which is provided with an iron core and a magnetic patch, wherein the iron core is punched by silicon-steel plates, a wedge-shaped port is punched on the silicon-steel plates, the iron core which is laminated by the silicon-steel plates has corresponding wedge-shaped slots, the cross section of the magnetic patch takes a wedge shape which is corresponding to the wedge-shaped slot, and the magnetic patch with the wedge shape is inserted into the wedge-shaped slot of the iron core. The technical scheme is adopted, the magnetic patch is inserted on the iron core through the structure of the wedge-shaped slot and is connected with the iron core reliably, when the rotor is operated, the magnetic patch can not escape, the magnetic path can be thinner, the magnetic patch consumption can be reduced, the materials are saved, the magnetic field distribution of the rotor is more rational, and the magnetic path loss is lower.
Description
Technical field
The utility model relates to permanent magnet generator, especially its rotor.
Background technology
At present, conventional small-power rotor of permanent-magnetic power generator, the employing punching silicon-steel that its iron core has is overrided to form, and magnetic patch is bonded on the iron core surface with special-purpose adhesive glue; The mild steel blank of the employing hot investment casting that has is made through machine work, and magnetic patch is made a call to two holes, is fastened on the iron core surface with stainless steel screw then.The former, is though have silicon steel material utilance height, advantage such as the magnetic patch consumption is few, owing to cohesive force is limited, when running up, the defective that exists magnetic patch to come off easily; Though the latter has rotor mechanical intensity advantages of higher, to take up room owing to connect the screw of magnetic patch and iron core, so there are defectives such as the material consumption amount is big, the magnetic patch consumption is big.
Summary of the invention
The technical problems to be solved in the utility model is: a kind of rotor of permanent-magnetic power generator that adopts silicon sheet core is provided, and its magnetic patch connects reliably on iron core, can not come off.
For achieving the above object, the technical solution of the utility model is: a kind of rotor of permanent-magnetic power generator, have iron core and magnetic patch, and its iron core is made for silicon steel sheet punching press stack, punching press wedge shape mouth on silicon steel sheet, the iron core that is formed by stacking by silicon steel sheet has corresponding wedge-shaped slot; The cross section of magnetic patch is and the corresponding wedge shape of wedge-shaped slot that the magnetic patch of wedge shape is inserted in the wedge-shaped slot of iron core.Adopt this technical scheme, magnetic patch is embedded on the iron core by wedge-shaped groove structure, is connected with iron core reliably, when rotor turns round, can not deviate from.
As improvement, between wedge shape mouth adjacent on the silicon steel sheet, have the swelling mouth, the iron core that is formed by stacking by silicon steel sheet then has corresponding expanding trough, after the magnetic patch of wedge shape inserts the wedge-shaped slot of iron core, inserts expanding rod in expanding trough.The cross section of expanding trough is the circular port of opening, and expanding rod is cylindrical, and its diameter is greater than the aperture of expanding trough.Adopt this technical scheme, can magnetic patch be clamped by expanding trough, like this, when the wedge-shaped slot of machine silicon steel disc, do not need to control very high precision, solved this desired problem very high of the fastening magnetic patch of wedge-shaped groove structure of utilizing the parts machining accuracy.
Other beneficial effect of the present utility model is: the further magnetic patch consumption of save silicon steel plate iron core rotor.Because adopt magnetic patch is bonded in scheme on the iron core; in order to guarantee the mechanical strength of magnetic patch; magnetic patch must have enough thickness; adopted the technical program; because the combination of wedge-shaped slot and wedge-shaped slot and expanding trough can be strengthened protection and support to magnetic patch, under the situation that guarantees magnetic patch magnetic flux, magnetic patch can be done thinnerly; promptly reduce the magnetic patch consumption, saved material.And, rotor of the present utility model, Distribution of Magnetic Field is more reasonable, and the magnetic circuit loss is lower.

Embodiment
As shown in Figure 1, rotor of permanent-magnetic power generator of the present utility model is equipped with iron core 2 on the main shaft 1 of rotor, and this iron core 2 is formed by stacking by silicon steel sheet, and magnetic patch 3 is housed on the iron core 2.
Shown in Fig. 2,3, iron core 2 is made for silicon steel sheet punching press stack, stamps out the wedge shape mouth on silicon steel sheet, when the iron core that is formed by stacking by silicon steel sheet just has corresponding wedge-shaped slot 4.Shown in Fig. 4,5, the cross section of magnetic patch 3 has and wedge-shaped slot 4 corresponding wedge shapes, and the magnetic patch 3 of wedge shape can be inserted in the wedge-shaped slot 4 of iron core 2.Adopt this technical scheme, magnetic patch 3 is embedded on the iron core 2 by wedge-shaped groove structure, when rotor turns round, can not deviate from.
Shown in Fig. 2,3, between wedge shape mouth adjacent on the silicon steel sheet, have the swelling mouth, this swelling mouth is the circular port with opening, the expanding trough 5 that the iron core that is formed by stacking by silicon steel sheet then has respective shapes.After the magnetic patch 3 of wedge shape inserts the wedge-shaped slot 4 of iron core 2, in expanding trough 5, insert the expanding rod 6 of diameter greater than the expanding trough diameter, expanding rod 6 can adopt steel nail.Like this, expanding rod 6 makes expanding trough 5 expansions, and the expanding trough 5 of expansion can clamp magnetic patch 3.Therefore, when the wedge shape mouth of machine silicon steel disc, can not need to control very high precision and can realize clamping, thereby solve this desired problem very high of the fastening magnetic patch of wedge-shaped groove structure of utilizing the parts machining accuracy to magnetic patch 3.
As shown in Figure 1, silicon steel sheet connects to form iron core 2 by rivet 7.Main shaft 1 is provided with the axial endplay that back-up ring 9 and jump ring 8 prevent rotor core,
