Embodiment
An embodiment of the stator bearing structure of electric rotating machine of the present invention is described with reference to the accompanying drawings.Fig. 1 is the sectional elevation figure of an embodiment of the stator bearing structure of electric rotating machine of the present invention.Fig. 2 is the partial sectional view of the part of the line A-A of band arrow in Fig. 1.
The stator support 2 that is used to support stator core 1 has stator support base plate 3 that constitutes the bottom and the stator support side plate 4 that constitutes two sides.In stator core 1, be mounted with one around horizontal axis rotor rotated (not shown).Axial two ends at stator support 2 are mounted with stator support end plate 20.20 places are equipped with bearing support plate 21 at the stator support end plate, and described bearing support plate 21 is by bearing 22 supporting rotor (not shown).
Stator support base plate 3 has two banded fixed heads 5 and a lamellar connecting plate 6 that is connected by welding to fixed head 5.Fixed head 5 extension of paralleling to the axis is clipped in axis wherein below electric rotating machine, and the load of supporting electric rotating machine.Connecting plate 6 horizontal-extendings are so that connect two fixed heads 5.Sole mount pad 8 is positioned to sole 9 on the fixed head 5 and contacts, and is soldered on the fixed head 5.Sole mount pad 8 extends along sole 9.In addition, between sole mount pad 8 and sole 9, spacer 10 is set.
8 places are provided with the screwed hole (not shown) at the sole mount pad.By bolt 11 and nut 12 spacer 10 and sole 9 are fastened on the sole mount pad 8.Bolt 11 passes screwed hole.Herein, as shown in Figure 2, the bolt 11 and the nut 12 of axial both sides of lower position that is set at end pressing plate 7 is fastening with each sole 9 rigidity.
As shown in Figure 1, between the inner surface of the two sides of end pressing plate 7 and stator support side plate 4, provide gap 13 to avoid direct connection.In addition, between the lower surface of end pressing plate 7 and connecting plate 6, provide gap 14 to make described lower surface directly not contact with connecting plate 6.
In order to have the sufficient intensity of anti-vibration, the stator support reinforcement side plate 15 that will form pack arrangement by welding is fixed to the top of stator support side plate 4, thereby has strengthened the rigidity of stator support side plate 4.
On the top of stator support 2 a gas pipeline (not shown) is installed, is used for circulating cooling gas.
According to the foregoing description, the same with the disclosed prior art of Japanese documentation No.3053947, utilize electromagnetic noise that gap 13 and 14 can suppress to be produced by stator core 1 to external transmission.
