Abstract
The invention relates to a rolling harmonic speed reducer which comprises an input end assembly. The speed reducer is characterized in that the periphery of the input end assembly is provided with a bearing assembly, the middle part of the bearing assembly is provided with a containing space, and a drive assembly is sleeved on the periphery of the containing space; the periphery of the drive assembly is provided with an external gear assembly, an output end assembly is sleeved on the operating end periphery of the bearing assembly, and the output end assembly is connected with the external gear assembly by virtue of a connecting screw; and an inner gear is doubly meshed with a corresponding external gear, thereby obtaining double torsion outputs, the couple of an integral structure is more balanced, the output is more stable, and the operation of the speed reducer is more stable. Therefore, double cylinders in an internal tooth cavity and a central shaft are manufactured into an integral crank shaft and are easy to control, thereby guaranteeing the working accuracy.
Description
Technical field
The present invention relates to a kind of speed reducer, relate in particular to a kind of rolling harmonic wave speed reducing machine.
Background technique
A kind of rolling harmonic wave speed reducing machine (Rolling Harmonious Reducer) is called for short the RH speed reducer.Through repetition test and test, 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 a kind of 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 prior art in order to solve, and a kind of rolling harmonic wave speed reducing machine is provided.
The object of the invention is realized through following technological scheme:
A kind of rolling harmonic wave speed reducing machine; Include the input end assembly; Wherein: described input end assembly outer periphery is equipped with bearing unit; The stage casing of said bearing unit is distributed with holding space; Described holding space outer race is provided with transmitting assemblies; Described transmitting assemblies outer periphery is equipped with the external gear assembly, and the working end outer race of described bearing unit is provided with cap assembly, and described cap assembly links to each other through attachment screw with the external gear assembly.
Further, above-mentioned a kind of rolling harmonic wave speed reducing machine, wherein: described transmitting assemblies is the internal tooth wheels, has at least two internal gears to form.
Further, above-mentioned a kind of rolling harmonic wave speed reducing machine, wherein: described bearing unit is the criss-crossing bearing.
Further, above-mentioned a kind of rolling harmonic wave speed reducing machine, wherein: be provided with oil leab in the described criss-crossing bearing.
Again further, above-mentioned a kind of rolling harmonic wave speed reducing machine, wherein: described criss-crossing bearing top is provided with connecting groove.
The advantage of technological scheme of the present invention is mainly reflected in: the two engagements through internal gear and corresponding external gear, obtain the output of double moment of torsion, and integrally-built couple balance more, and to export more stablely, speed reducer work is more steady.Thus, can make whole bent axle to bicylindrical in the interior tooth cavity and central shaft, be easy to control, make machining accuracy be guaranteed.Also make the more compact structure of whole part simultaneously, precision is higher, and the rigidity of one-piece parts is better, and whole strength has only half.And the rigidity of part is bigger, is not easy to damage.Moreover, can in total, get minimum back clearance.
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 rolling harmonic wave speed reducing machine.
1 input end assembly, 2 criss-crossing bearings
3 external gear assemblies, 4 cap assemblies
5 attachment screws, 6 internal gears
7 oil leabs, 8 connecting grooves
Embodiment
A kind of rolling harmonic wave speed reducing machine as shown in Figure 1 includes input end assembly 1, and its specialization is: input end assembly 1 outer periphery that the present invention adopted is equipped with bearing unit.Specifically, in order to have better engagement effect, be distributed with holding space in the stage casing of bearing unit, this holding space outer race is provided with transmitting assemblies.Corresponding is to be equipped with external gear assembly 3 in the transmitting assemblies outer periphery with it.Simultaneously, outer race is provided with cap assembly 4 in the working end of bearing unit.Moreover, consider the stable of work of the present invention, cap assembly 4 links to each other through attachment screw 5 with external gear assembly 3.
With regard to the present invention's one preferred implementation, in order to realize the output of high pulling torque, the transmitting assemblies that is adopted is the internal tooth wheels, has at least two internal gears 6 to form.Thus, can carry out two engagements at least, obtain the output of double moment of torsion.
Further, in order to improve the deceleration effect, the bearing unit of employing is a criss-crossing bearing 2.And, consider the smooth and easy of running, in criss-crossing bearing 2, be provided with oil leab 7.Moreover, consider the follow-up needed mechanical part of the enough effective connections of ability, be provided with connecting groove 8 on criss-crossing bearing 2 tops.
Can find out through above-mentioned character express, adopt the present invention after, mesh with the two of corresponding external gear through internal gear, obtain the output of double moment of torsion, and integrally-built couple balance more, export more stablely, speed reducer work is more steady.Thus, can make whole bent axle to bicylindrical in the interior tooth cavity and central shaft, be easy to control, make machining accuracy be guaranteed.Also make the more compact structure of whole part simultaneously, precision is higher, and the rigidity of one-piece parts is better, and whole strength has only half.And the rigidity of part is bigger, is not easy to damage.Moreover, can in total, get minimum back clearance.
