Abstract
The utility model discloses a novel generator housing fixing structure. The novel generator housing fixing structure comprises a housing, wherein a stator is sleeved inside the housing; an inner threaded hole is disposed in the housing; an inner threaded hole is disposed in the position corresponding to the stator; a fastening screw penetrates sequentially through the inner threaded hole of the housing and the inner threaded hole of the stator, and fixes the housing and the stator. According to the structure, an inner threaded hole is disposed in the housing, an inner threaded hole is disposed in the position corresponding to the stator, the fastening screw penetrates through the inner threaded holes of the housing and the stator sequentially, and thus the housing and the stator are fixed together. Although an expanded housing is larger than a stator silicon steel plate in high temperature, the fastening screw can prevent the housing from detaching from the silicon steel plate. The fastening screw, to a certain degree, can reduce the shrinkage of the housing in low temperature, and thus the housing is prevented from cracking. According to the novel generator housing fixing structure, the motor housing and the stator are fixedly fastened, and furthermore the service life of the motor housing is prolonged.
Description
Technical field
The utility model relates to a kind of electric generator structure, relates in particular to a kind of shell fixed structure of novel electricity generator.
Background technology
At present, in the generator on the market, the shell of generator generally adopts metal material; Many employing aluminum hulls, and stator adopts silicon steel sheet more, because shell and stator adopt material different; The coefficient of expansion is different, the expansion of shell and stator and shrink different when generator uses.Because the coefficient of expansion of aluminium shell is greater than the stator silicon steel sheet, under the normal temperature, shell and stator are fixing firm, but when high temperature, the aluminium shell expands greater than the stator silicon steel sheet, thereby the aluminium shell is prone to throw off with silicon steel sheet; During low temperature, the aluminium shell shrinks greater than the stator silicon steel sheet, thereby the aluminium shell is prone to split.
Summary of the invention
The purpose of the utility model provides the shell fixed structure of the novel electricity generator of a kind of motor housing and stator fixation.
Be the realization above-mentioned purpose, the shell fixed structure of a kind of novel electricity generator of the utility model, it comprises shell; Be arranged with stator in the shell; Said shell is provided with internal thread hole, and the stator corresponding position also is provided with internal thread hole, and jackscrew wears the internal thread hole fixed housing and the stator of shell and stator successively.
Said shell is a metal-back.
Said shell is an aluminum hull.
Said stator is a silicon steel sheet.
Adopt the structure of the utility model, on shell, be provided with internal thread hole, the stator corresponding position also is provided with internal thread hole, and jackscrew wears the internal thread hole of shell and stator successively, thereby shell and stator are fixed together.When high temperature, though shell expands greater than the stator silicon steel sheet, jackscrew can prevent shell and silicon steel sheet disengagement; During low temperature, jackscrew reduces the contraction of shell to a certain extent, thereby prevents that shell from splitting.The structure of the utility model not only can make motor housing and stator fixation, and can prolong the useful life of motor housing.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is done further detailed explanation:
Fig. 1 is the structural representation of the shell fixed structure of the utility model generator.
Embodiment
As shown in Figure 1; The shell fixed structure of a kind of novel electricity generator of the utility model; It comprises shell 1, is arranged with stator 2 in the shell 1, and said shell 1 is provided with internal thread hole 3; Stator 2 corresponding positions also are provided with internal thread hole 4, and jackscrew 5 wears internal thread hole 3,4 fixed housings 1 and the stator 2 of shell 1 and stator 2 successively.
Adopt above structure, on shell 1, be provided with internal thread hole 3, stator 2 corresponding positions also are provided with internal thread hole 4, and jackscrew 5 wears the internal thread hole 3,4 of shell 1 and stator 2 successively, thereby shell 1 and stator 2 are fixed together.When high temperature, though shell 1 expands greater than stator silicon steel sheet 2, jackscrew 5 can prevent shell 1 and 2 disengagements of stator silicon steel sheet; During low temperature, jackscrew 5 reduces the contraction of shell 1 to a certain extent, thereby prevents that shell 1 from splitting.
Said shell 1 is a metal-back.
Said shell 1 is an aluminum hull.
Said stator 2 is a silicon steel sheet.
