Abstract
The utility model discloses a stator mounting structure for an automobile AC generator, which has better heat dissipation effect. The stator mounting structure comprises a front end cover and a stator, wherein the stator core of the stator is completely accommodated in the front end cover, and the stator and the front end cover are in interference fit with each other and are positioned through bolt through holes. The utility model has the advantages that as the stator is wrapped inside the front end cover, the surface area of a heating part of the generator is enlarged in the premise of an unchanged outer diameter of the stator, thereby increasing the convective heat exchange capacity between air and the surface of a heating source of the generator, and improving the heat dissipation and cooling effects; the stator core is completely embedded in a casing, so as to achieve an easier control of the coaxiality between the generator stator and a generator rotor, and help prolong the overall service life of the AC generator and reduce electromagnetic noises; and the stator core is completely embedded in the casing to enhance the external strength of the generator, thereby prolonging the service life of the generator.
Description
Technical field
The utility model relates to a kind of motorcar alternator, especially a kind of stator mounting structure of motorcar alternator.
Background technology
The building block of motorcar alternator comprises the housing that stator, rotor and forward and backward end cap etc. are formed.In the present motorcar alternator stator mounting structure, stator connects forward and backward end cap as connector, rotor is connected front and back ends by bearing and covers, the mounting means that adopts the front and rear cover seam to cooperate with the stator seam, the front and back ends cover surrounds stator, but stator core partly exposes, and heat exchange is carried out as thermal component and cross-ventilation in the stator core surface, to reach the purpose of heat radiation.
Said structure is from the angle of protection generator, and have certain hidden danger: at first, radiating effect is not very desirable, can influence the useful life of generator and some parts, for generator, the quality of heat radiation directly influences the function life-span of generator own; Secondly, this iron core exposes the seam axiality that structure need be handled the stator two ends well, increased the control point, deviation appears in stator, the bad relatively control of rotor coaxial degree when mounted easily, and axiality missionary society causes the vibration of rotor, electromagnetic noise increases, if under high-speed case, phase mutual friction possibly between stator and the rotor causes whole generating machine thrashing.
The utility model content
In order to overcome the relatively poor deficiency of stator mounting structure radiating effect that existing motorcar alternator stator core exposes, technical problem to be solved in the utility model provides the better motorcar alternator stator of a kind of relative existing structure radiating effect mounting structure.
The technical scheme that its technical problem that solves the utility model adopts is: motorcar alternator stator mounting structure, comprise front end housing and stator, and the stator core of stator all is contained in the front end housing, interference fit between stator and the front end housing.
Utilize bolt via hole location between described stator and the front end housing.
The beneficial effects of the utility model are: because stator is wrapped in front end housing inside, under the constant prerequisite of stator outer diameter, can increase generator heating part surface area, improve generator pyrotoxin surface and cross-ventilation heat exchange amount, improve the effect of radiating and cooling; Stator core is flush-mounted in the housing fully, is easier to control the axiality of motor stator and rotor, helps the raising of alternating current generator bulk life time and reduces electromagnetic noise; Stator core is flush-mounted in the housing fully, and the generator external intensity is increased, thus the useful life of having improved generator itself.
Description of drawings
Fig. 1 is an assembling schematic diagram of the present utility model.
Fig. 2 is an axonometric drawing of the present utility model.
Be labeled as 1-stator, 2-front end housing, 11-stator core, the outlet of 12-stator, 3-bolt via hole among the figure.
Embodiment
Below in conjunction with accompanying drawing the utility model is further specified.
As shown in Figure 1 and Figure 2, motorcar alternator stator mounting structure of the present utility model comprises front end housing 2 and stator 1, and the stator core 12 of stator 1 all is contained in the front end housing 2, stator 1 and front end housing 2 interference fit.Under the constant prerequisite of stator 1 external diameter, can increase generator radiator portion surface area, improve generator pyrotoxin surface and cross-ventilated heat exchange amount, improve the effect of radiating and cooling; Stator core 11 is flush-mounted in the housing of front end housing 2 fully, is easier to control the axiality of motor stator and rotor, helps the raising of alternating current generator bulk life time and reduces electromagnetic noise; Stator core 11 is flush-mounted in front end housing 2 housings fully, and the generator external intensity is increased, thereby prolongs generator useful life, reduces the generator failure rate.
The quality of alternating current generator temperature rise has determined the good and bad of generator quality, uses mounting structure of the present utility model, and heat radiation has certain effect to generator.
This mounting structure of the present utility model, stator and front end housing are interference fit, and the pattern tool advances front end housing with stator press-loading, as inner part, can control the axiality of generator to stator better, is directly cooperated by front and rear cover, and stator also is difficult for deformation like this.And be the installation of connector with the stator, need handle the seam axiality at two ends well, increased the control point.More convenient axiality and the concentricity that guarantees generator in installation process of the utility model, electromagnetic noise and motor self vibration to reduce generator improve the alternating current generator quality.
Because of the general securing member that is connected that adopts stud as front end housing and rear end cap, for convenient for assembly, should adopt bolt via hole 3 location this moment between stator 1 and the front end housing 2, thereby improve the efficiency of assembling of complete machine.As shown in Figure 2, offer the corresponding bolt via hole 3 in position on stator 1 and the front end housing 2, so that connect with bolt.
