Abstract
The utility model provides a generator magnetic pole, includes the magnetic pole body, and magnetic pole body middle part is equipped with the cylindrical shaft hole, and magnetic pole body periphery upwards extends and forms a plurality of claw utmost point, and the structure that radix unguis to claw point reduces is gradually very followed to each claw, and the claw point surface of each claw utmost point is drawn close to axle hole center line gradually. Increase the tapering through disc outside magnetic pole claw pole tip portion, when sending out high -speed operation of motor, magnetic pole claw pole tip portion is out of shape outside expansion, because there is the tapering in magnetic pole claw pole tip portion, in its outside expansion back, still keeps there is sufficient air gap between round in magnetic pole excircle and the stator core, can directly not produce the friction. The utility model discloses can stop that the magnetic pole surface is applicable to automobile -used generator with the direct fricative trouble of stator core when the generator is high -speed rotatory.
Description
Technical field
This utility model relates to a kind of generator magnetic pole.
Background technology
At present, the magnetic pole that the magnetic pole of alternator for vehicle typically uses outer surface to be disc, so at electromotor high-speed cruising
Time, magnetic pole pawl point periphery can expand outwardly under centrifugal action, thus can cause the air gap between magnetic pole and stator core
(being commonly called as main air gap) diminishes, even can cause time serious magnetic pole outer surface with stator core direct friction, therefore, at main air gap relatively
Little occasion, the electromotor using common magnetic pole is to be difficult to meet require.
Summary of the invention
The purpose of this utility model is to overcome the above-mentioned deficiency of prior art to provide a kind of generator magnetic pole, this magnetic pole
Magnetic pole outer surface can be stopped when electromotor high speed rotating with the fault of stator core direct friction, it is adaptable to electric generating
Machine.
The technical solution adopted in the utility model is to achieve these goals:
A kind of generator magnetic pole, including magnetic pole body 1, is provided with cylindrical bore, magnetic pole body 1 week in the middle part of magnetic pole body 1
While upwardly extend several pawl poles 2 of formation, each pawl pole 2 is from radix unguis to the pawl diminishing structure of point, outside the pawl point of each pawl pole 2
Surface is gradually drawn close to axis hole centrage.
Pawl pole 2 is evenly distributed on magnetic pole body 1 periphery.
Pawl pole 2 is 6,7 or 8.
The pawl point outer surface of each pawl pole 2 is positioned at same taper seat, and the radix unguis outer surface of each pawl pole 2 is positioned at same cylinder
Face.
Between pawl point 3 cone elements and the bus of pawl pole periphery, angle is 2 °-3 °, a length of 8-12mm of cone element.
The beneficial effects of the utility model are: by increasing tapering at magnetic pole pawl pole tip portion periphery, high at electromotor
During speed operating, the deformation of magnetic pole pawl pole tip portion expands outwardly, owing to magnetic pole pawl pole tip portion is tapered, after it expands outwardly, and magnetic pole
There remains enough air gaps between cylindrical and stator core inner circle, will not directly produce friction.At present, this utility model examination
It is used on JFZ2928 electromotor, does not find tribological failure.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is top view of the present utility model.
Fig. 3 is profile of the present utility model.
Fig. 4 is pawl point enlarged drawing of the present utility model.
Detailed description of the invention
With example, this utility model is further described below in conjunction with the accompanying drawings:
A kind of generator magnetic pole as shown in Figure 1, 2, 3, including magnetic pole body 1, magnetic pole body 1 is provided with circular shaft bore,
Magnetic pole body 1 upwardly extends several pawl poles 2 of formation, and each pawl pole 2 is from the diminishing structure in radix unguis portion to hook tip, each pawl
The hook tip appearance of pole 2 is gradually drawn close towards axis hole centrage, and pawl pole 2 is evenly distributed on magnetic pole body 1 periphery, and pawl pole 2 is 6,7
Or 8, the hook tip outer surface of each pawl pole 2 is positioned at same taper seat, and the radix unguis portion outer surface of each pawl pole 2 is positioned at same circle
Cylinder.The side of pawl point 3 is cone, and pawl point 3 is on pawl pole 2, and pawl point 3 is a part for pawl pole 2, and the most each pawl point 3 has
Tapering (being a conical surface).
-3 °, angle β=2 °, cone element 7 between pawl point 3 cone elements 7 and the bus 6 of pawl pole 2 periphery as shown in Figure 4
Length L=8-12mm.
