Abstract
The utility model relates to an inlaid double-layer rolling harmonic drive reducer which comprises an input end assembly and is characterized in that a connecting shaft is sleeved at the periphery of the input end assembly, and the periphery of the connecting shaft is connected with an external gear at an inner layer through an internal gear assembly at the inner layer. Meanwhile, a bearing assembly is sleeved at the periphery of the external gear at the inner layer, an accommodating space is distributed in the middle segment of the bearing assembly, an internal gear assembly at an outer layer is sleeved at the periphery of the accommodating space, and an external gear at the outer layer is sleeved at the periphery of the internal gear assembly at the outer layer. Therefore, output doubling that of a torque of a single layer is obtained through meshing double gears with the potential difference of 180 DEG, and the whole structure is more balance in force couple and more stable in output, and the reducer is more stable in work. In addition, the external gear at the inner layer is used as double cylinders at the outer layer to be meshed with the external gear at the outer layer so that a whole part is more compact in structure, higher in precision, better in rigidity and not easy to damage.
Description
Technical field
The utility model relates to a kind of speed reducer, relates 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.
The model utility content
The purpose of the utility model 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 purpose of the utility model realizes through following technological scheme:
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 inserted double-deck rolling harmonic wave speed reducing machine, wherein: described bearing unit is the criss-crossing bearing.
Further, above-mentioned inserted double-deck rolling harmonic wave speed reducing machine, wherein: be provided with oil leab in the described criss-crossing bearing.
Further, above-mentioned inserted double-deck rolling harmonic wave speed reducing machine, wherein: described criss-crossing bearing top is provided with connecting groove.
Again further, above-mentioned 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 the utility model technological scheme 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 purpose of the utility model, advantage and characteristics will illustrate through the non-limitative illustration of following preferred embodiment and explain.These embodiments use the prominent example of the utility model technological scheme, and all technological schemes of taking to be equal to replacement or equivalent transformation and forming all drop within the scope of the utility model requirement protection.In the middle of these accompanying drawings,
Fig. 1 is the organigram of inserted double-deck rolling harmonic wave speed reducing machine.
1 input end assembly, 2 coupling shafts
3 internal layer internal gears, 4 internal layer external gears
5 outer internal gear 6 outer external gears

Embodiment
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 utility model adopted is provided with coupling shaft 2.
And,, adopted the double-deck layout of nesting type in order to reach double reduction.Specifically, the utility model 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 utility model 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 utility model 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 utility model 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 utility model 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.
