Abstract
The utility model relates to a novel type high strength generator base which comprises a generator base body in a cylindrical shape. The inner wall of the generator base body is welded with at least four axially arranged reinforced plates. Two bottom feet are symmetrically welded at the two sides of the lower part of the generator base body; the reinforced plates of the bottom feet are welded between the base feet and the outer wall of the base body. A non-drive end ring is welded on the base body at a position of the non-drive end part of the reinforced plates. The generator base of the utility model is provided with a welded structure which is simple and compact. Convenient and rapid to mount, the overall strength of the base is increased; the noise and vibration of a power generator can also be reduced; all these factors contribute to the prolonging of its service lifetime. A stator core can be mounted inside the base through a press mounting method and can be thereafter fixed by pins. Convenient to mount and able to achieve high precision, the production capability of the power generator can also be increased. The introduction of a welded structure enables all connection parts in the base do not have gaps, which increases the IP protection grade generally and ensures that the power generator can stably and reliably function for a middle-and-long time on sea or in an outdoor hostile environment.

Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail.
As shown in Figure 1, 2, the utility model comprises machine base body 2, machine base body 2 is cylindrical, the inwall of machine base body 2 is welded with 4 gussets 6 that axially arrange, consider the bulk strength of support, conventionally need to arrange at least 4 gussets 6 that axially arrange, all gussets 6 can be symmetrical arranged, also can asymmetricly arrange, can determine according to the structure that is arranged on stator core wherein.2 footing 4 are symmetrically welded at the both sides of machine base body 2 bottoms, footing gusset 5 is welded between footing 4 and the outer wall of machine base body 2, anti-drive end end ring 3 is welded on the anti-drive end place of machine base body 2 and gusset 6, in the present embodiment, machine base body 2 is rolled and is formed by steel plate, 1 gusset 6 is welded on seam 201 places of steel plate, and footing gusset 5 vertically arranges.The drive end place of machine base body 2 and gusset 6 is welded with transition connector 1, and transition connector 1 is for the installation of diesel engine, and transition connector 1 is made up of the first ring flat-plate 101, female connector brace rod 102 and the second ring flat-plate 103 welding.
In the utility model, each part no longer adopts bolt mechanical connection, but adopts Type of Welding.The footing 4 of support directly and machine base body 2 integrally welded, and reinforce with footing gusset 5, anti-drive end end ring 3 is directly welded on the cylinder of machine base body 2, has ensured well the assembly precision of non-drive end shield.Gusset 6 is welded on the inwall of machine base body 2, for the press-fiting and locate of stator core, also can strengthen the bulk strength of support.
