Be equipped with needle bearing in the axis hole of all gears.
All gear two ends are provided with the axle shelves.
The utility model mainly adopts the secondary tooth group of a main tooth group and two symmetries to form, has only a bearing in main tooth group and the secondary tooth group, be main shaft and countershaft, all gears on main tooth group and the secondary tooth group are connected in series combination vertically, and all corresponding gear on main tooth group and the secondary tooth group are meshed.Make overall structure simplification, stable drive, decelerability reliable like this, and volume is little, in light weight.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is a structural representation of the present utility model.
Embodiment
Shown in Figure 1, the utility model comprises housing 4, cover plate 1, and housing 4 and cover plate 1 are spirally connected and are that one, gear train are installed in the cavity of housing 4 and cover plate 1 composition.Described gear train is made up of the secondary tooth group of a main tooth group and two symmetries.Main tooth group is made up of three utmost point gears, and chopped-off head gear 2 is made of gear and the input shaft that is connected as a single entity with it, and the input shaft center is provided with axis hole, and input shaft is provided with keyway; Tail level gear 7 is identical with chopped-off head gear 2 structures, and just size is different, and both installation directions are opposite, and promptly increment is all inside; Middle rank gear 8 is by two superimposed one that constitute of gear that diameter is different, and its center is provided with the axis hole of being used to lead to.Chopped-off head gear 2, intermediate gear 8 and tail level gear 7 are connected in series same main shaft 10 successively, and the output shaft on input shaft on the chopped-off head gear 2 and the tail level gear 7 stretches out the bearing 9 of cover plate 1 and housing 4 bottoms respectively.The gear of secondary tooth group is made up of the two poles of the earth gear at least, and the gear number of poles of secondary tooth group lacks one than main tooth group.Head level gear 3 is identical with final stage gear 6 structures, installation direction is identical, by two superimposed formation one of gear that diameter is different, the center is provided with the axis hole of being used to lead to, head level gear 3 and final stage gear 6 be by same countershaft 5 serial connections, and the two ends of countershaft 5 are contained in bearing 9 holes on cover plate 1 and the housing 4.Gearwheel engagement on chopped-off head gear 2 and two level gear 3, small gear on the head level gear 3 and the engagement of the gearwheel on the intermediate gear 8, small gear on the middle rank gear 8 and the engagement of the gearwheel on the final stage gear 6, the small gear on the final stage gear 6 is meshed with tail level gear 7.Be equipped with needle bearing in the axis hole of all gears, to reduce volume.All gear two ends are equipped with the axle shelves.Further increase reduction speed ratio as need, only need to increase a kind of the getting final product in intermediate gear 8 and head level or the final stage.During work, the rotation of driven by motor input shaft, thereby the chopped-off head gear that is connected as a single entity 2 drives 3 rotations of two, left and right sides level gear, small gear on two level gear 3 drives the gearwheel rotation on the intermediate gear 8 again, small gear on the middle rank gear 8 drives the gearwheel rotation on the final stage gear 6 again, small gear on the final stage gear 6 drives 7 rotations of tail level gear again, the power output after the output shaft of last tail level gear 7 will slow down.Because the corresponding gear of main tooth group and two secondary tooth groups meshes, be not prone to the phenomenon of main shaft 10 stressed bendings, the gear engagement on the both sides of all gears on the main tooth group and the secondary tooth group, stress equalization transmits steadily, and it is little to wear and tear, and noise is also little.All gears on main tooth group and the secondary tooth group adopt coaxial serial connection mode, have saved the space greatly, have reduced volume, and material therefor is also few, and processing cost is lower.
