Abstract
The utility model discloses an automotive generator claw pole comprising a claw pole body. The claw pole body is provided with an iron core. The claw pole and the iron core are provided with an axle hole respectively. The claw pole body is extended upwards to form a plurality of claws. The transverse section diameter of each claw is gradually reduced from bottom to top. According to the automotive generator claw pole of the utility model, a magnetic pole can be formed on the tip of each claw so as to form a controlled magnetic field instead of nonuniform magnetic force line distribution, so the magnetic flux leakage can be reduced to a great extent, and the noise can be reduced; when two claw poles are engaged to each other, the dynamic equilibrium of the claw poles in the rotation process can be facilitated; and at the same time, the shape of each claw is changed from bottom to top, so the installation process can be facilitated.
Description
Technical field
The utility model relates to auto parts machinery field, the pawl utmost point particularly using on a kind of automobile current generator.
Background technology
At present, the pawl utmost point is the important component part of automobile generator rotor, two pawl extreme pressures of rotor needs close and form, in generator operation process, rotor, a pawl utmost point just drives another pawl utmost point to rotate together in stator, in the time having direct current to pass through in the winding of magnetic field, the pawl utmost point is magnetized, and has just formed rotating magnetic field.The claw of the tradition pawl utmost point is arranged to square, in the process of rotation, due to the skewness in magnetic field, turns the magnetic field in air gap between stator and is significantly offset, and produces immediately noise.And the shape of the pawl utmost point causes in running, the air drag being subject to is larger, and friction nature also becomes greatly, and the heat of generation is just many, and heat radiation is just more difficult, thereby has a strong impact on the whole service life of generator.
Summary of the invention
The purpose of this utility model is the pawl utmost point that provides a kind of in order to solve above-mentioned the deficiencies in the prior art and increase the service life, reduce on the automobile current generator of noise.
To achieve these goals, the pawl utmost point of the designed a kind of automobile current generator of the present invention, comprise pawl utmost point body, described pawl utmost point body is provided with iron core, on the described pawl utmost point and iron core, be respectively equipped with axis hole, described pawl utmost point body upwards extends to form several claws, and the lateral cross section diameter of described claw reduces from bottom to top gradually.
Further, the axis of described iron core and the pawl utmost point coincides, and the axis of described axis hole coincides.
Further, described pawl utmost point claw is along upwards extending to form perpendicular to body place plane.
Further, the described pawl utmost point and iron core is one-body molded.
Further, described iron core is arranged to circular.
Further, described claw is evenly distributed on the periphery of pawl utmost point body.
Further, described claw quantity is six.
The utility model compared with prior art, there is following beneficial effect: 1, because the claw lateral cross section diameter of the pawl utmost point reduces gradually from bottom to top, can be at the most advanced and sophisticated magnetic pole that forms of claw, thereby form controlled magnetic field, rather than the magnetic line of force pockety, reduce to a great extent leakage field, reduced noise.
2, iron core and pawl are extremely one-body molded, and pawl utmost point claw, perpendicular to body place plane, in the time that two pawls are extremely engaged, is conducive to the dynamic equilibrium of the pawl utmost point in rotary course.
3, claw form variation from bottom to top, is convenient to install.
Accompanying drawing explanation
Fig. 1 is the utility model automobile current generator dewclaw utmost point three-dimensional structure diagram;
Fig. 2 is the upward view of the utility model Fig. 1 automobile current generator dewclaw utmost point.
In figure: pawl utmost point body 1, iron core 2, pawl utmost point claw 3, axis hole 4.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Please refer to shown in accompanying drawing, the pawl utmost point of a kind of automobile current generator that the utility model obtains, comprise pawl utmost point body 1, described pawl utmost point body 1 is provided with iron core 2, on the described pawl utmost point 1 and iron core 2, be respectively equipped with axis hole, described pawl utmost point body upwards extends to form several claws 3, and the lateral cross section diameter of described claw reduces from bottom to top gradually.
Described iron core 2 coincides with the axis of the pawl utmost point 1, and the axis of described axis hole coincides.
Described pawl utmost point claw 3 is along upwards extending to form perpendicular to body place plane.
Described the pawl utmost point 1 and iron core 2 are one-body molded.
Described iron core 2 is arranged to circular.
Described claw 3 is evenly distributed on the periphery of pawl utmost point body.
The quantity of described claw 3 is six.
The utility model, because the claw lateral cross section diameter of the pawl utmost point reduces from bottom to top gradually, can form magnetic pole at claw tip, thereby form controlled magnetic field, rather than the magnetic line of force pockety, reduces to a great extent leakage field, has reduced noise.
Iron core and pawl are extremely one-body molded, and pawl utmost point claw, perpendicular to body place plane, in the time that two pawls are extremely engaged, is conducive to the dynamic equilibrium of the pawl utmost point in rotary course.
Due to the variation from bottom to top of claw form, be convenient to install simultaneously, reduced cost.
