Embodiment
Execution mode 1
Below, with reference to the accompanying drawings of embodiments of the present invention.
Fig. 1 is the front schematic view of the electric rotating machine of embodiment of the present invention.
As shown in Figure 1, stator 10 has stator core 1a and coil windings 1b.Stator core 1a is stacked the forming of parts that the metal sheet with forcing press punching press electromagnetic steel plate etc. is formed.This stator core 1a, at its radial outside, has housing stationary plane 1c.In addition, keep the housing 2 of stator core 1a to there is the stator installed surface 3 in opposite directions with this housing stationary plane 1c.
By stator 10 is accommodated in housing 2, between the housing stationary plane 1c of stator 10 and the stator installed surface 3 of housing 2, form gap 4.In addition, at the radially inner side of stator 10, configuration is assembled in the rotor 6 of axle 5 rotationally.
Fig. 2 means the stator 10 of electric rotating machine and the part sectioned view of the standing part of housing 2 of embodiment of the present invention 1.
As shown in Figure 2, in gap 4, formed adhesive linkage 9.This adhesive linkage 9 contains plastochondria 7 and bond material 8.This bond material 8 is impregnated between plastochondria 7 and plastochondria 7, by the stator installed surface 3 of the housing stationary plane 1c of stator 10, housing 2 and plastochondria 7 bonding and combination mutually.
At this, the thickness of establishing adhesive linkage 9 is the average diameter of G, plastochondria 7 while being D, and its big or small ratio is the degree of D/G≤1/3.
Fig. 3 means the figure of example of the section shape of plastochondria 7.Fig. 3 (A) represents the solid of circular, and Fig. 3 (B) represents roughly I font, roughly L font, an example of the solid of V font roughly.
For the kind of bond material 8, except the organic bonding agent of acrylic-based adhesives etc., also can adopt mineral-type bonding agent of cement etc. etc.
Below, referring to figs. 1 through Fig. 4, the example of manufacture method of the electric rotating machine of embodiment of the present invention 1 is described.The plastochondria 7 adopting in the electric rotating machine obtaining by this manufacture method, comprises the plastochondria 7 that the metal material of using the material identical with stator core 1a or the material identical with coil 1b to form forms.
Fig. 4 uses the metal sheet of electromagnetic steel plate etc. to pressurize processing and the obsolete material 12 of the obsolete material 11 that produces while forming stator core 1a, the coil windings 1b schematic diagram during as plastochondria 7.
In this embodiment, first, as shown in Figure 4, to the processing of pressurizeing of the metal sheet of electromagnetic steel plate etc., obtain for forming the sheet metal of roughly T font of a part of each layer of stator core 1a.Fig. 4 represents the remaining metal sheet after the part of T font is roughly stamped, and roughly the part of T font is not shown.The sheet metal of the roughly T font obtaining is configured to circle, and, stacked in paper direction (direction parallel with the axle of Fig. 1), thus stator core 1a formed.
Then, coil 1b is wrapped in to the stator core 1a obtaining like this and above forms stator 10.The stator 10 obtaining is like this contained in to housing 2, thereby forms gap 4 between the housing stationary plane 1c of stator 10 and the stator installed surface 3 of housing 2.
Then, a plurality of plastochondrias 7 and bond material 8 are put into gap 4.At this, plastochondria 7 is following acquisitions: in Fig. 4, pressurizeing man-hour, punching out the roughly sheet metal of T font, the obsolete material 11 that the metal sheet from remaining therefrom (part shown in Fig. 4 bend) is obtained, the obsolete material 12 of coil windings are slightly broken.Such obsolete material 11,12 during for plastochondria 7, consider the thickness of iron core laminated plate (metal sheet), the wire diameter of coil windings (magnet-wire) etc., the lower limit of the average diameter D of plastochondria 7 is about 0.1mm.
In technology before, in order to ensure adhesive strength, the thickness of adhesive linkage is set in below 0.1mm, preferably set in 0.03～0.1mm left and right.But by casting while manufacturing housing 2, the dimensional tolerance of the housing 2 after the demoulding is ± 2～10mm left and right for example.Therefore,, after the shaping of housing 2, if do not carry out the processing of appending of stator installed surface 3, adhesive linkage is thicker than 0.1mm sometimes.
Therefore, there is the situation of adhesive linkage thickening, thus the problem that exists adhesive strength to reduce.
According to present embodiment, filling plastochondria 7 in the gap 4 between the housing stationary plane 1c of stator 10 and the stator installed surface 3 of housing 2, with bond material 8 fixed stators 10, so, even the in the situation that of adhesive linkage 9 thickening, also can high strength ground fixed stator 10.
In addition, the use amount of bond material 8 can be reduced, manufacturing cost can be suppressed.
In addition, when the metal material of iron, copper etc. is used for to plastochondria 7, the thermal diffusivity of adhesive linkage 9, magnetic properties improve, and can improve the characteristic of product.
In addition, in the present embodiment, in gap 4 between the housing stationary plane 1c of stator 10 and the stator installed surface 3 of housing 2, put into plastochondria 7, this plastochondria 7 adopts the metal sheet of electromagnetic steel plate etc. the pressurize obsolete material 11 producing while being processed to form stator core 1a, the obsolete material 12 of coil windings 1b, so, obsolete material is recycling, improves the stock utilization in factory.
As shown in Figure 2, can first plastochondria 7 be put into gap 4, and then inject bond material 8.Like this, plastochondria 7 and bond material 8 can be put into respectively to gap 4.Or the material that also can in advance plastochondria 7 and bond material 8 be mixed is put into gap 4.No matter which kind of situation is included in the present invention.
In addition, at the broken process of pressurization processing, obsolete material and between the operation of the interior formation adhesive linkage 9 in gap 4, conventionally free sluggish.Therefore, think: the roughly T font sheet metal that certain specific once pressurization processing is obtained and the plastochondria 7 that specifically adds the obsolete material generating man-hour as this are fewer for the situation of the manufacture of same electric rotating machine.But, even if this situation is also contained in the present invention.Certainly, certain batch of roughly T font sheet metal producing and by the obsolete material obtaining with this sheet metal different batches (the pressurization of homogeneous processing) situation for the manufacture of an electric rotating machine, be also contained in the present invention, this is self-evident.
In addition, the situation that the obsolete material producing while manufacturing electric rotating machine except all plastochondria 7 use that are placed in gap 4 forms, can be also that a part that is placed into the plastochondria 7 in gap 4 forms with this obsolete material.
Fig. 5 is the front schematic view of the electric rotating machine of embodiment of the present invention.
Present embodiment, except rotor 6 is located at the outer peripheral face side this point of stator 10, all the other are identical with execution mode 1.For identical or corresponding part, note is with identical or corresponding mark, and its explanation is omitted.
According to present embodiment, there is the effect identical with execution mode 1.
