Abstract
The invention relates to an embedded two-layer harmonic drive reducing gear, which comprises a wave generator. The output end of the wave generator is provided with an input shaft, and a cam is arranged outside the input shaft. The embedded two-layer harmonic drive reducing gear is characterized in that inner-layer flexible bearings are distributed outside the cam; and an inner-layer flexible wheel is sleeved outside the inner-layer flexible bearings. Furthermore, an inner-layer steel wheel is sleeved outside the inner-layer flexible wheel, and outer-layer flexible bearings are sleeved outside the inner-layer steel wheel. Meanwhile, an outer-layer flexible wheel is sleeved outside the outer-layer flexible bearings, and an outer-layer steel wheel is sleeved outside the outer-layer flexible wheel. Therefore, double-layer harmonic waves are realized, and can achieve a higher gear ratio than the conventional single-layer harmonic waves. Meanwhile, due to the elliptical fit design, the accuracy and the efficiency are higher than single harmonic waves. The huge torque output can be realized; and in addition, the embedded two-layer harmonic drive reducing gear is precise in structure, small in size and compact in structure, easily adopts to different installation places and deserves promotion and application.
Description
Technical field
The present invention relates to a kind of speed reducer, relate in particular to a kind of inserted double-deck harmonic driving speed reducer.
Background technique
Harmonic wave drive speed reducer is to utilize the controllable resiliently deformable of flexible member to come the mechanical transmission of transmitting movement and power.Because harmonic wave drive speed reducer has many advantages, has been widely used in fields such as the energy, electronics industry, petrochemical industry, war industry, robot, lathe, instrument and apparatus, medical apparatus at present.
But existing harmonic driving speed reducer all is the structure of individual layer, for the difficult realization of higher speed change.Simultaneously, the harmonic wave rate is not high, can't realize the output of super large moment of torsion.And because the demand of precise structure degree can cause whole apparatus structure excessive, it is compact inadequately to distribute.
Summary of the invention
The objective of the invention is to overcome the above problem that existing technology exists, a kind of inserted double-deck harmonic driving speed reducer is provided.
For realizing a kind of inserted double-deck harmonic driving speed reducer of the object of the invention; Include wave-generator, the output terminal of said wave-generator is provided with input shaft, and described input shaft is equipped with cam outward; Wherein: described cam is distributed with the internal layer flexible bearing outward; Described internal layer flexible bearing is arranged with the internal layer flexbile gear outward, and described internal layer flexbile gear is arranged with the internal layer steel wheel outward, and described internal layer steel wheel is arranged with outer flexible bearing outward; Described outer flexible bearing is arranged with outer flexbile gear outward, and described outer flexbile gear is arranged with outer steel wheel outward.。
Further, above-mentioned a kind of inserted double-deck harmonic driving speed reducer, wherein, described internal layer steel wheel cylindrical is oval.
Adopt technological scheme of the present invention, realized double-deck harmonic wave, more can realize high gear ratio than existing individual layer harmonic wave.Simultaneously, owing to adopt oval-shaped identical design, make precision and efficient higher than single harmonic wave.Thus, also can realize the moment of torsion output of super large.And because the present invention constructs precision, volume can be very little, and structure is very compact, is easy to adapt to different installation sites, is worthy of popularization.
The object of the invention, advantage and characteristics will illustrate through following preferential embodiment's non-limitative illustration and explain that these embodiments only provide with reference to accompanying drawing as an example.
Description of drawings
Fig. 1 is the organigram of this inserted double-deck harmonic driving speed reducer.
The implication of each reference character is following among the figure:
1 input shaft, 2 cams
3 internal layer flexible bearings, 4 internal layer flexbile gears
5 internal layer steel wheels, 6 outer flexible bearings
7 outer flexbile gear 8 outer steel wheels
Embodiment
A kind of inserted double-deck harmonic driving speed reducer as shown in Figure 1; Include wave-generator; The output terminal of this wave-generator is provided with input shaft 1, and cam 2 is installed outside input shaft 1, and its unusual part is: the cam 2 outer internal layer flexible bearings 3 that are distributed with that the present invention adopted.Specifically, outside internal layer flexible bearing 3, be arranged with internal layer flexbile gear 4.Further, the internal layer flexbile gear 4 outer internal layer steel wheels 5 that are arranged with are arranged with outer flexible bearing 6 outside the internal layer steel wheel 5.Simultaneously, be arranged with outer flexbile gear 7 outside the outer flexible bearing 6, be arranged with outer steel wheel 8 outside this skin flexbile gear 7.
With regard to the present invention's one preferred implementation, the cylindrical of the internal layer steel wheel 5 that is adopted is for oval.
From implementation process of the present invention, internal layer flexbile gear 4, outer flexbile gear 7 can be worked in coordination with and constituted the flexbile gear assembly.Corresponding with it is that outer steel wheel 8 can also be formed steel wheel unit with internal layer steel wheel 5.Specifically, wave-generator, flexbile gear assembly, steel wheel unit can be fixed one arbitrarily among the three, and all the other two one is that initiatively one is driven, can realize like this slowing down or speedup (fixed drive ratio).Simultaneously, also become two inputs, differential gearing is formed in an output.
Further: fixing when internal layer flexbile gear 4, wave-generator is that initiatively when internal layer steel wheel 5 was driven, internal layer flexbile gear 4 produced distortion under the wave-generator effect, realizes 5 outputs of internal layer steel wheel.Afterwards, the internal layer steel wheel 5 of oval cylindrical is outer field active as outer field wave-generator, and outer flexbile gear 7 is deformed, and is promptly as shown in Figure 1.Then, outer steel wheel 8 outputs, the internal layer flexbile gear 4 at double-deck place, major axis of wave generator two ends and wheel engagement fully just.Meanwhile, place, minor axis of wave generator two ends, internal layer flexbile gear 4 is thrown off with internal layer steel wheel 5 fully.Like this, make internal layer flexbile gear 4 and internal layer steel wheel 5 be in incomplete engagement.Because the continuous rotation of wave-generator, make engaging-in, mesh, nibble out, throw off fully these four kinds of situation fully and change successively, circulation is endlessly.Moreover in conjunction with real work, owing to realized double-deck harmonic wave, both single reduction speed ratio is n, and then total reduction speed ratio is n*n.
Through above-mentioned character express and combine accompanying drawing to find out, adopt the present invention after, realized double-deck harmonic wave, more can realize high gear ratio than existing individual layer harmonic wave.Simultaneously, owing to adopt oval-shaped identical design, make precision and efficient higher than single harmonic wave.Thus, also can realize the moment of torsion output of super large.And because the present invention constructs precision, volume can be very little, and structure is very compact, is easy to adapt to different installation sites, is worthy of popularization.
Certainly, more than only be concrete exemplary applications of the present invention, protection scope of the present invention is not constituted any limitation.Except that the foregoing description, the present invention can also have other mode of execution.All employings are equal to the technological scheme of replacement or equivalent transformation formation, all drop within the present invention's scope required for protection.
