Embodiment
Shown in accompanying drawing 1 and accompanying drawing 2, be the stereogram and the three-dimensional exploded view of the utility model.As shown in the figure, the utility model mainly is provided with one by upper pedestal 11 and lower base 12, and the body 1 formed of base 13, in body 1, is provided with a reducing gear 2.This reducing gear 2 comprises a main drive gear 21, and engagement is contacted with a plurality of driven gears 22 of this main drive gear 21, and the positioning disk 3 and the reel 4 of exerting oneself that supply these driven gear 22 engagement contacts.Wherein, this main drive gear 21, and a plurality of driven gears 22 that engagement is contacted with this main drive gear 21 are placed in a fixed base 5 is provided with the perforate 51 with these driven gears 22 respective amount in fixed base 5, for these driven gear 22 emergences;
This driving gear 21 is articulated in a cover seat 6; Make cover seat 6 overlap the transmission shaft that is fixed in motor, and be nested with plural bearing 61 in this cover seat 6, this positioning disk 3 and the reel 4 of exerting oneself are respectively equipped with ring tooth 31 and another ring tooth 41 in inner edge; Make both ring tooths 31 be made as the different numbers of teeth with another ring tooth 41; 42 upper pedestal 11 emergences of the axostylus axostyle of this reel 4 of exerting oneself by body 1, and be nested with bearing 43 and oil sealing 44, for articulating different transmitting assembliess;
By the combination of aforementioned components, constitute a tooth differential speed reducer.When motor drives main drive gear 21 rotations; So that as these driven gears 22 as the planet along ring tooth 31 rotations of positioning disk 3, and then the drive reel 4 of exerting oneself is by the positioning disk 3 and the reel 4 of exerting oneself; The gear ratio that ring tooth 31 and another ring tooth 41 are different; Forming the amplification of the number of teeth, and then increase the torsion of the axostylus axostyle 42 of the reel 4 of exerting oneself, and make the volume of speed reducer and length be able to dwindle.
Shown in accompanying drawing 3 and accompanying drawing 4, be the part sectional view and the reducing gear planimetric map of the utility model.As shown in the figure; The utility model is after assembling, and wherein these driven gears 22 make its upper and lower half section to mesh another ring tooth 41 that is contacted with the reel 4 of exerting oneself respectively by the set perforate 51 outside emergences of fixed base 5; And the ring tooth 31 of positioning disk 3; Because this ring tooth 31 be different gear ratios with another ring tooth 41, with the amplification of the formation number of teeth, when driven gear 22 when positioning disk 3 rotates; Can increase the torsion of the axostylus axostyle 42 of the reel 4 of exerting oneself by the tooth difference, and make speed reducer reach the effect of the fast big torsion low frictional factor of big ratio, low noise.
