Abstract
The invention relates to an embedded dual-layer rolling harmonious reducer which comprises an input end assembly and is characterized in that a connecting shaft is sleeved on the periphery of the input end assembly, and inner layer external gears are connected to the periphery of the connecting shaft through an inner layer internal gear assembly. Meanwhile, a bearing assembly is sleeved on the peripheries of the inner layer external gears, an accommodating space is arranged at the middle section of the bearing assembly, an outer layer internal gear assembly is sleeved on the periphery of the accommodating space, and outer layer external gears are sleeved on the periphery of the outer layer internal gear assembly. Therefore, through meshing of two gears with a position difference of 180 DEG, the embedded dual-layer rolling harmonious reducer obtains the output of two times of torque compared with that of the single-layer rolling harmonious reducer, has more balance of couple and more stable output of the integral structure, and works more stably. Meanwhile, the inner layer external gears are used for dual cylinders to be meshed with the outer layer external gears, so that embedded dual-layer rolling harmonious reducer has more compact structure, higher precision, higher rigidity and difficulty in damage.
Description
Technical field
The present invention relates to a kind of speed reducer, relate in particular to a kind of inserted double-deck rolling harmonic wave speed reducing machine.
Background technique
Rolling harmonic wave speed reducing machine (Rolling Harmonious Reducer) is called for short the RH speed reducer.We are through repetition test and test, and the small column in interior wheel chamber moves in a circle, and the poor tooth engagement of external gear makes it motion, thereby carries out being meshing with each other of tooth and tooth with foreign steamer in can realizing.Because small column revolution one whole circle, corresponding point just reaches an extreme value, promptly walks a tooth, thereby reaches the effect of deceleration.
But existing rolling harmonic wave speed reducing machine Percent of contact area is low, and output is unstable, causes whole operating mode unstable.Moreover whole part rigidity is little, influences the working life of speed reducer middle (center) bearing.
Summary of the invention
The object of the invention is exactly the problems referred to above that exist in the existing technology in order to solve, and a kind of inserted double-deck rolling harmonic wave speed reducing machine is provided.
The object of the invention is realized through following technological scheme:
A kind of inserted double-deck rolling harmonic wave speed reducing machine; Include the input end assembly, wherein: described input end assembly outer race is provided with coupling shaft, and described coupling shaft periphery is connected with the internal layer external gear through internal layer internal gear assembly; The outer race of said internal layer external gear is provided with bearing unit; The stage casing of said bearing unit is distributed with holding space, and described holding space outer race is provided with outer internal gear assembly, and the outer race of said outer internal gear assembly is provided with outer external gear.
Further, above-mentioned a kind of inserted double-deck rolling harmonic wave speed reducing machine, wherein: described bearing unit is the criss-crossing bearing.
Further, above-mentioned a kind of inserted double-deck rolling harmonic wave speed reducing machine, wherein: be provided with oil leab in the described criss-crossing bearing.
Further, above-mentioned a kind of inserted double-deck rolling harmonic wave speed reducing machine, wherein: described criss-crossing bearing top is provided with connecting groove.
Again further, above-mentioned a kind of inserted double-deck rolling harmonic wave speed reducing machine, wherein: described internal layer internal gear assembly has at least two internal layer internal gears to constitute, and described outer internal gear assembly has at least two outer internal gears to constitute.
The advantage of technological scheme of the present invention is mainly reflected in: through the engagement of 180 ° of bidentates of potential difference wheel, obtain the output than the double moment of torsion of individual layer, and integrally-built couple balance more, export more stablely, speed reducer work is more steady.As outer bicylindrical and the engagement of outer field external gear, make the more compact structure of whole part to the internal layer external gear, precision is higher, and the rigidity of one-piece parts is better, and is not easy to damage.
Description of drawings
The object of the invention, advantage and characteristics will illustrate through the non-limitative illustration of following preferred embodiment and explain.These embodiments use the prominent example of technological scheme of the present invention, and all technological schemes of taking to be equal to replacement or equivalent transformation and forming all drop within the scope of requirement protection of the present invention.In the middle of these accompanying drawings,
Fig. 1 is the organigram of this inserted double-deck rolling harmonic wave speed reducing machine.

Embodiment
A kind of inserted double-deck rolling harmonic wave speed reducing machine as shown in Figure 1 includes input end assembly 1, and its unusual part is: input end assembly 1 outer race that the present invention adopted is provided with coupling shaft 2.And,, adopted the double-deck layout of nesting type in order to reach double reduction.Specifically, the present invention is connected with internal layer external gear 4 in the periphery of coupling shaft 2 through internal layer internal gear 3 assemblies.Simultaneously, the outer race at internal layer external gear 4 is provided with bearing unit.Linking for the ease of whole speed reducer is more closely stable, and the bearing unit that the present invention adopts is distributed with holding space in the stage casing, is provided with outer internal gear 5 assemblies in the holding space outer race.Corresponding with it is, is provided with outer external gear 6 in the outer race of outer internal gear 5 assemblies.Thus, can realize double reduction, equilibrium of couples makes the more stable double moment of torsion of output, and integral rigidity is better.
With regard to the present invention's one preferred implementation, do not influence the stability of work when satisfying compact structure, the whole running precision of order is higher, and the bearing unit that the present invention uses is a criss-crossing bearing 7.Simultaneously, in criss-crossing bearing 7, be provided with oil leab, satisfy long-time running requirements of one's work.
Further, consider and to play firm effectively linking effect, be provided with connecting groove 8 on criss-crossing bearing 7 tops.
Moreover internal layer internal gear 3 assemblies that adopt for the output that realizes double moment of torsion have at least two internal layer internal gears 3 to constitute.Same, outer internal gear 5 assemblies have at least two outer internal gears 5 to constitute.
Can find out through above-mentioned character express, adopt the present invention after, through the engagement of 180 ° of bidentates wheels of potential difference, obtain output, and integrally-built couple balance more than the double moment of torsion of individual layer, export more stablely, speed reducer work is more steady.As outer bicylindrical and the engagement of outer field external gear, make the more compact structure of whole part to the internal layer external gear, precision is higher, and the rigidity of one-piece parts is better, and is not easy to damage.
