Abstract
The utility model relates to a rolling harmonic speed reducer, which comprises an input end assembly and is characterized in that a bearing assembly is arranged on the periphery of the input end assembly, containing space is distributed on the middle section of the bearing assembly, and a transmission assembly is sleeved on the periphery of the containing space. In addition, an outer gear assembly is arranged on the periphery of the transmission assembly, an output end assembly is sleeved on the periphery of the working end of the bearing assembly, and the output end assembly is connected with the outer gear assembly through a connecting screw. Therefore, output of double torsion is obtained through double mesh of an inner gear and a corresponding outer gear, couple of a whole structure is balanced, output is stable, and work of the speed reducer is stable. Double cylinders in an inner gear cavity and a central shaft are formed into a whole crank shaft, and the rolling harmonic speed reducer is easy to control and enables processing accuracy to be guaranteed.
Description
Technical field
The utility model relates to a kind of speed reducer, relates in particular to a kind of 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.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 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 rolling harmonic wave speed reducing machine is provided.
The purpose of the utility model realizes through following technological scheme:
The rolling harmonic wave speed reducing machine; Include the input end assembly, wherein: described input end assembly outer periphery is equipped with bearing unit, and 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 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 rolling harmonic wave speed reducing machine, wherein: described bearing unit is the criss-crossing bearing.
Further, above-mentioned rolling harmonic wave speed reducing machine, wherein: be provided with oil leab in the described criss-crossing bearing.
Again further, above-mentioned rolling harmonic wave speed reducing machine, wherein: described criss-crossing bearing top is provided with connecting groove.
The advantage of the utility model technological scheme 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 the.And the rigidity of part is bigger, is not easy to damage.Moreover, can in total, get minimum back clearance.
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 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
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 utility model 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 the utility model work, cap assembly 4 links to each other through attachment screw 5 with external gear assembly 3.
With regard to the utility model 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 utility model 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 the.And the rigidity of part is bigger, is not easy to damage.Moreover, can in total, get minimum back clearance.
