Detailed description of the invention
Further illustrate technical scheme below in conjunction with the accompanying drawings and by detailed description of the invention.
As shown in Figures 1 to 4, present embodiments provide for a kind of electric machine support, including the first cylindrical portion 2 being set within stator core 1, the first cylindrical portion 2 and stator core 1 interference fit.
In the present embodiment, internal by the first cylindrical portion 2 of electric machine support being set in stator core 1, realize both fixing by the interference fit between the first cylindrical portion 2 and stator core 1 simultaneously, thus, improve the versatility of electric machine support, even if the length of stator core 1 changes, as long as the internal diameter of stator core 1 does not changes, above-mentioned support all can be used to be fixed.
The end of the first cylindrical portion 2 is provided with the guide part guided when the first cylindrical portion 2 inserts stator core 1.Concrete, guide part is the second cylindrical portion 3 of the end being arranged on the first cylindrical portion 2, and the first cylindrical portion 2 and the second cylindrical portion 3 are coaxially disposed.The size being smaller in size than the first cylindrical portion 2 external diameter of the second cylindrical portion 3 external diameter.The axial length of the first cylindrical portion 2 is longer than the length of the second cylindrical portion 3, and the length of described first cylindrical portion 2 is more than the first cylindrical portion 2 and half of the second cylindrical portion 3 length sum.
In the present embodiment, by arranging guide part in the end of the first cylindrical portion 2, i.e. arranging the second cylindrical portion 3, the external diameter of the second cylindrical portion 3 and length are respectively less than the size of the first cylindrical portion 2, it can play the effect of guiding when the first cylindrical portion 2 inserts stator core 1.It is easy to the first cylindrical portion 2 and inserts stator core 1.
First cylindrical portion 2 exterior circumferential scribbles bonding agent, and the first cylindrical portion 2 and stator core 1 are connected by bonding agent.By arranging bonding agent outside the first cylindrical portion 2, can further improve electric machine support and the structural strength of stator core 1 cooperation.
Being provided with several grooves 4 in first cylindrical portion 2, groove 4 is along the axial distribution of the first cylindrical portion 2.Fluting quantity can be 2,3 ..., can be to be uniformly distributed between M, and several grooves 4, it is possible to uneven distribution.By the setting of groove 4 structure, produced stress when the first cylindrical portion 2 and stator core 1 interference fit can be discharged, eliminates, it is to avoid stress concentrates the first cylindrical portion 2 caused to deform.For the ease of the processing of groove 4, groove 4 can also run through the first cylindrical portion 2 and the second cylindrical portion 3 is arranged.
Second cylindrical portion 3 be internally provided with bearing chamber, and the length of the second cylindrical portion 3 is more than the degree of depth of bearing chamber.The stress of axial direction when the first cylindrical portion 2 can be avoided to coordinate with stator core 1 acts on the external diameter of bearing chamber, prevents bearing chamber from deforming.
It is provided with the positioning convex 5 along its axial distribution in first cylindrical portion 2, stator core 1 inwall is provided with the detent 6 matched with positioning convex 5.Concrete, positioning convex 5 is consistent with the length of detent 6, by positioning convex 5 and the cooperation of detent 6, electric machine support and stator core 1 location in a circumferential direction can be realized, the problem preventing arranged in dislocation, the simultaneously size being smaller in size than the first cylindrical portion 2 of the second cylindrical portion 3, therefore, electric machine support and stator core 1 are when circumferential registration, and the second cylindrical portion 3 can play the effect of guiding.
In order to above-mentioned electric machine support carries out the explanation of a step, present embodiment additionally provides above-mentioned electric machine support and the concrete assembling process of stator:
The first step: coat bonding agent on the first cylindrical portion 2 circumference；
Second step: by the guiding electric rotating machine support in the second circle portion 3, positioned in alignment protruding 5 and detent 6；
3rd step: electric machine support is pressed into stator core 1 interior to electric machine support step surface, completes to install.
In the present embodiment, additionally providing a kind of motor, it includes electric machine support as described above.
The know-why of the present invention is described above in association with specific embodiment.These describe the principle being intended merely to explain the present invention, and can not be construed to limiting the scope of the invention by any way.Based on explanation herein, those skilled in the art need not pay performing creative labour can associate other detailed description of the invention of the present invention, within these modes fall within protection scope of the present invention.
