Abstract
The utility model discloses a speed reducer, comprising a fixed inner gear and an output inner gear which are connected coaxially. A planetary support is further disposed between the fixed inner gear and the output inner gear and provided with two planetary gear components, each planetary gear component consists of a main planetary gear and a slave planetary gear which are connected coaxially, the main planetary gear is meshed in the fixed inner gear, the slave planetary gear is meshed in the output inner gear, and the main planetary gear is meshed with a driving gear. The speed reducer can realize single-stage speed reduction with high speed reduction ratio, and has the advantages of small return stroke gap between an output shaft and an input shaft, high efficiency, small volume, light weight and low cost.
Description
Technical field
The utility model belongs to mechanical field, is specifically related to a kind of speed reducer.
Background technique
In order to obtain the transmission of high reduction speed ratio, the most effective way is that two or more speed reducer cascades are obtained at present.Its shortcoming is that the backhaul gap is big between the inlet shaft and outlet shaft, and efficient is low, volume is big, Heavy Weight.
The model utility content
For overcoming deficiency of the prior art, the purpose of this utility model is to provide between a kind of inlet shaft and outlet shaft the backhaul gap little, and efficient height, volume are little, lightweight speed reducer.
In order to solve the problems of the technologies described above, realize above-mentioned purpose, the utility model has adopted following technological scheme:
A kind of speed reducer, the fixed annulus and the output inner gear that comprise a coaxial connection, it also comprises delegation's prong frame, described planet stent is provided with two planetary gear sets, described each planetary gear set constitutes by a pair of coaxial fixedly connected main planetary gear with from planetary pinion, described main planetary gear is engaged in the described fixed annulus, describedly is engaged in the described output inner gear described main planetary gear and driving gear engagement from planetary pinion.
Further, the number of teeth of described fixed annulus and output inner gear is different.
Preferably, in order to obtain high reduction speed ratio, the number of teeth difference of described fixed annulus and output inner gear is smaller or equal to 5.
Preferably, the number of teeth of described output inner gear is more than the described fixed annulus number of teeth, the relative driving gear reversing drive of then described output inner gear.
Preferably, the number of teeth of described output inner gear is less than the described fixed annulus number of teeth, the transmission in the same way of the relative driving gear of then described output inner gear.
The utlity model has following advantage:
Driving gear rotation of the present utility model drives main planetary gear rotation and revolution, drives the output inner gear rotation from planetary rotation and revolution.The single-stage reduction speed ratio is easy to reach 1: 1000, can reach more than 1: 4000.
The inlet shaft and outlet shaft backhaul gap of speed reducer of the present utility model is little, efficient is high, volume is little, in light weight, cost is low.
Above-mentioned explanation only is the general introduction of technical solutions of the utility model, for can clearer understanding technological means of the present utility model, and can be implemented according to the content of specification, below with preferred embodiment of the present utility model and conjunction with figs. describe in detail as after.Embodiment of the present utility model is provided in detail by following examples and accompanying drawing thereof.

Embodiment
Below in conjunction with drawings and Examples technology implementation process of the present utility model is described further.
Referring to shown in Figure 1, a kind of speed reducer, comprise a fixed annulus 6 and an output inner gear 1, it also comprises delegation's prong frame 2, described planet stent 2 is provided with two planetary gear sets 7, and described each planetary gear set 7 constitutes by a pair of coaxial fixedly connected main planetary gear 4 with from planetary pinion 3, and described main planetary gear 4 is engaged in the described fixed annulus 6, describedly be engaged in the described output inner gear 1 described main planetary gear 4 and a driving gear 5 engagements from planetary pinion 3.
Further, described fixed annulus 6 is different with the number of teeth of output inner gear 1.
Preferably, in order to obtain high reduction speed ratio, the number of teeth difference of described fixed annulus 6 and output inner gear 1 is smaller or equal to 5.
Preferably, the number of teeth of described output inner gear 1 is more than described fixed annulus 6 numbers of teeth, then described output inner gear 1 relative driving gear reversing drive.
Preferably, the number of teeth of described output inner gear 1 is less than described fixed annulus 6 numbers of teeth, then described output inner gear 1 relative driving gear transmission in the same way.
The foregoing description just is to allow the one of ordinary skilled in the art can understand content of the present utility model and enforcement according to this for technical conceive of the present utility model and characteristics being described, its objective is, can not limit protection domain of the present utility model with this.The variation or the modification of every equivalence of having done according to the essence of the utility model content all should be encompassed in the protection domain of the present utility model.
