Embodiment
With reference to the accompanying drawings and examples, the embodiment of the present invention is described in further detail.Implement below
Example is used to illustrate the present invention, but is not limited to the scope of the present invention.
The present invention a kind of large gear manufacture method manufacture large gear structure as shown in Figure 1, Figure 2 and Figure 3, this
A kind of large gear manufacture method of invention comprises the following steps：
1) the independent gear teeth 1 are made, the gear teeth 1 include outer grinningly 4 and positioned at grinningly burying tooth root 5 under 4 lower ends outside；
2) make mold, the gear teeth 1 are embedded in advance during mold is manufactured, the gear teeth 1 have it is multiple, it is described
For multiple gear teeth 1 according to the shaped formation of gear, the mold is annular in shape, and tooth root 5 is buried under described and is placed in the mold；
3) use electric furnace smelting molten iron, the pouring molten iron into mold, control cooling velocity in casting process, avoid ftractureing,
The retainer ring 2 for being installed with the gear teeth 1 is obtained, the center section of retainer ring 2 is provided with through hole；By forming retainer ring after casting
2, the gear teeth 1 are integrated with the casting of retainer ring 2.
4) composite casting slurry is made；
5) rotating shaft mounting seat 6 is made；
6) electromagnetic type shaking device is selected, the retainer ring 2 is placed on bumper, and the rotating shaft mounting seat 6 is put
In in the through hole and at the center of retainer ring 2；
7) to the composite casting slurry is poured between rotating shaft mounting seat 6 and retainer ring 2, while pouring into described compound
