Embodiment Construction

[0016] The technical implementation process of the present invention will be further described below with reference to the accompanying drawings and embodiments.

[0017] see figure 1 As shown, a reducer includes a fixed internal gear 6 and an output internal gear 1, and also includes a planetary carrier 2 on which two planetary gear assemblies 7 are arranged, and each planetary gear The assembly 7 is composed of a pair of coaxial fixedly connected main planetary gears 4 and slave planetary gears 3, the main planetary gear 4 is meshed with the fixed internal gear 6, and the slave planetary gear 3 is meshed with the output internal gear 1, the main planetary gear 4 meshes with a driving gear 5.

[0018] Further, the fixed internal gear 6 and the output internal gear 1 have different numbers of teeth.

[0019] Preferably, in order to obtain a high reduction ratio, the difference in the number of teeth between the fixed internal gear 6 and the output internal gear 1 is less tha...

Abstract

The invention discloses a speed reducer. The speed reducer comprises a fixed inner gear, an output inner gear and a planet bracket, wherein the fixed inner gear and the output inner gear are connected coaxially; the planet bracket is arranged between the fixed inner gear and the output inner gear and provided with two planet gear components; each planet gear component consists of a pair of driving planet gear and driven planet gear connected coaxially; the driving planet gear is engaged in the fixed inner gear; the driven planet gear is engaged in the output inner gear; and the driving planet gear is engaged with a driving gear. The speed reducer provided by the invention can realize single-stage high-reduction ratio speed reduction and has the characteristics of small backlash interval between an output shaft and an input shaft, high efficiency, small size, light weight and low cost.

Description

technical field [0001] The invention belongs to the field of machinery, and in particular relates to a reducer. Background technique [0002] At present, in order to obtain a transmission with a high reduction ratio, the most effective way is to cascade two or more reducers. The disadvantage is that the return clearance between the outgoing and incoming shafts is large, the efficiency is low, the volume is large, and the weight is heavy. SUMMARY OF THE INVENTION [0003] In order to overcome the deficiencies in the prior art, the purpose of the present invention is to provide a reducer with small return clearance between the outgoing and incoming shafts, high efficiency, small size and light weight. [0004] In order to solve the above-mentioned technical problems and realize the above-mentioned purpose, the present invention adopts the following technical solutions: [0005] A reducer includes a fixed inner gear and an output inner gear that are coaxially connected, and...
