Abstract
The invention discloses a generator claw pole and is to provide the generator claw pole which has relatively-strong magnetic flux, relatively-low noise and strong heat dissipation performance. The radial cross section of each pole claw is approximately in trapezoid shape. The side, where the relatively-long bottom edge locates, of the trapezoid is the pole claw inner wall, and the side where the relatively-short bottom edge locates is the pole claw outer wall. The pole claw inner wall faces to the rotation axis of a claw pole body. The radial cross section of the pole claw of the generator claw pole is in trapezoid shape; the width of the pole claw inner wall is larger than the width of the pole claw outer wall; and under the condition of guaranteeing the size of working face pole claw distance, the space of the inner side of the pole claw is fully utilized, so that the cross section of the pole claw is allowed to be increased, the magnetic resistance is reduced, the magnetic flux is enhanced, and the output power of a generator is improved. When the generator claw pole is rotating axially, the internally-big externally-small structure of the pole claw can enable the air contacted with the structure to flow outside in an accelerating manner under the effect of the centrifugal force, thereby reducing the noise generated when the air is flowing to the axis direction, and improving the heat dissipation performance of a generator stator assembly.
Description
Technical field
The present invention relates to a kind of magnetic conduction device, more particularly, it relates to a kind of generator claw pole.
Background technology
The pawl utmost point is for AC generator for vehicle, and in the rotor of excitation, function plays magnetic conduction effect, and along with the progress of automotive engineering, the power consumption equipment on car constantly increases, and power consumption is more and more higher.Along with comfort level increase and the requirement to environment of well-behaved car, noise-reducing is inevitable.
Although the existing pawl utmost point is satisfied with general designing requirement, in structure, also has larger utilized space, so generator power potential also can further develop.During conventional working rotor, the pawl utmost point is used air because of the reason of utmost point pawl and flows to axis direction, produces larger noise, is unfavorable for the heat radiation of the field frame assembly of generator.
Summary of the invention
The deficiency existing for prior art, the object of the present invention is to provide a kind ofly there is stronger magnetic flux, compared with low noise, generator claw pole that heat-sinking capability is strong.
For achieving the above object, the invention provides following technical scheme: a kind of generator claw pole, comprise pawl utmost point body, described pawl utmost point body is revolving body, and described pawl utmost point body periphery is provided with equally distributed several utmost point pawl, and described pawl utmost point body and pawl are very wholely set, described utmost point pawl radial section is trapezoidal substantially, described trapezoidal place, longer base side is utmost point pawl inwall, and place, shorter base side is pawl utmost point outer wall, and described utmost point pawl inwall is towards pawl utmost point body revolution axle center.
Described utmost point pawl inwall and utmost point pawl outer wall are arc surface.
Described four trapezoidal angles are fillet.
By adopting technique scheme, the utmost point pawl radial section of this generator claw pole is trapezoidal substantially, utmost point pawl inwall width is greater than utmost point pawl outer wall width, guaranteeing in the size situation of working face utmost point pawl spacing, make full use of the space of utmost point pawl inner side, the cross section of utmost point pawl is increased, reduce magnetic resistance, strengthen magnetic flux, so output of a generator is increased; This generator claw pole is in axial-rotation work, in set utmost point pawl large outer little structure can guide under the effect of the air that is in contact with it and centrifugal force, accelerate outside mobile, reduce the noise that air flows and produces toward axis direction, and improved the heat-sinking capability of generator unit stator assembly.

Embodiment
Referring to figs. 1 through Fig. 3, generator claw pole embodiment of the present invention is described further.
A kind of generator claw pole, comprise pawl utmost point body 1, described pawl utmost point body 1 is revolving body, described pawl utmost point body 1 periphery is provided with equally distributed several utmost point pawl 2, described pawl utmost point body 1 is very wholely set with pawl, and described utmost point pawl 2 radial sections are trapezoidal substantially, and described trapezoidal place, longer base side is utmost point pawl inwall 21, place, shorter base side is pawl utmost point outer wall, and described utmost point pawl inwall 21 is towards pawl utmost point body 1 revolution axle center.Utmost point pawl 2 radial sections of this generator claw pole are trapezoidal substantially, described trapezoidal place, longer base side is utmost point pawl inwall 21, place, shorter base side is pawl utmost point outer wall, be that utmost point pawl inwall 21 width are greater than utmost point pawl outer wall 22 width, guaranteeing in the size situation of working face utmost point pawl 2 spacing, make full use of the space of utmost point pawl 2 inner sides, the cross section of utmost point pawl 2 is increased, reduce magnetic resistance, strengthen magnetic flux, so output of a generator is increased, compare the pawl utmost point of formed objects, this generator claw has lower magnetic resistance and the magnetic flux of Geng Gao; This generator claw pole is in axial-rotation work, the interior large outer little structure of set utmost point pawl 2 can guide under the effect of the air that is in contact with it and centrifugal force, accelerate outside mobile, reduce the noise that air flows and produces toward axis direction, and improved the heat-sinking capability of this generator unit stator assembly.
Described utmost point pawl inwall 21 and utmost point pawl outer wall 22 are arc surface.This generator claw pole is when axial-rotation is worked, and described arc surface can reduce gas-flow resistance, reduces the generation of noise.
Described four trapezoidal angles are fillet 23.This generator claw pole is when axial-rotation is worked, and described fillet 23 can reduce gas-flow resistance, reduces the generation of noise.
