Description
Technical field
The utility model relates to a kind of retarder, specifically relate to a kind of spring cycloidal reducer.
Background technique
Cycloidal reducer is a kind of applying row planetary transmission principle, adopts the novel transmission device of cycloidal pin teeth engagement.The whole transmission device of cycloidal planetary gear speed reducer can be divided into three parts: input part, deceleration part, output.Input shaft is equipped with two eccentric bushings of a dislocation 180 °, eccentric bushing is equipped with the roller bearing that two are called pivoted arm, the center hole of formation H mechanism, two cycloid wheel is the raceway of rotary arm bearing on eccentric bushing, and be meshed with the pin tooth of one group of annular array on pin gear by cycloid wheel, to form the internal messing reducing gear that tooth difference is a tooth, (in order to reduce friction, in the speed reducer that speed ratio is little, with pin gear sleeve on pin tooth).When input shaft rotates one week with eccentric bushing, due to the feature of tooth curve in cycloid wheel and by the event of pin gear upper pin gear restriction, the motion of cycloid wheel becomes the plane motion that existing revolution has again rotation, when the positive turn-week of input shaft, eccentric bushing also rotates one week, and cycloid wheel turns over a tooth in opposite direction thus slowed down, relend and help W output mechanism, by the low speed spinning motion of cycloid wheel by bearing pin, pass to output shaft, thus obtain lower output speed.
But the cycloidal reducer existed in the market is due to the structure of itself, and its axial force is zero, so gerotor structure can not bear larger axial impact force, makes the application of cycloidal reducer also have received restriction.
Summary of the invention
In order to overcome above-mentioned existing problem, the utility model provides a kind of spring cycloidal reducer that can bear large load, improve working life.
The utility model solves the technological scheme that its technical problem adopts: a kind of spring cycloidal reducer, comprise support, be located at input shaft and the output shaft of support, be located at the capacity eccentric bearing of input shaft, be located at the cycloid wheel of capacity eccentric bearing, be located at the pinwheel of cycloid wheel external tooth, be located at the pivoted arm of cycloid wheel, pinwheel is connected with support, and the internal tooth of pinwheel is meshed with the external tooth of cycloid wheel, pivoted arm is connected with output shaft, gap is had between described pivoted arm and cycloid wheel, gap is provided with the belleville spring of the impact for alleviating axial force, and butterfly spring is placed on the input shaft place between pivoted arm and cycloid wheel.
Pivoted arm is fixed in described belleville spring one end, and the other end is fixed on cycloid wheel.
Described cycloid wheel is two, is located at two rollers of capacity eccentric bearing respectively.
Described pivoted arm is made up of pin, column sleeve, and column sleeve is evenly distributed with many pins.
Described pivoted arm is connected with two eccentric wheels by pin.
Described output shaft is connected with column sleeve, and is integral type connection.
The beneficial effects of the utility model are, go out to be provided with butterfly spring at output shaft, when cycloid is subject to axial impact, by the distortion of butterfly spring, alleviate the impact axially, thus increase the physical life of the part of speed reducer.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is the overall structure schematic diagram of the utility model embodiment.
In figure: 1. support, 2. input shaft, 3. output shaft, 4. capacity eccentric bearing, 5. cycloid wheel, 6. pinwheel, 7. pivoted arm, 8. pin, 9. column sleeve, 10. belleville spring.
Embodiment
In order to make technical problem to be solved in the utility model, technological scheme and beneficial effect clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Figure 1, a kind of spring cycloidal reducer, comprises support 1, is located at the input shaft 2 of support 1 and output shaft 3, is located at the capacity eccentric bearing 4 of input shaft 2, is located at the cycloid wheel 5 of capacity eccentric bearing 4, is located at the pinwheel 6 of cycloid wheel 5 external tooth, is located at the pivoted arm 7 of cycloid wheel 5; Cycloid wheel 5 is two, is located at two rollers of capacity eccentric bearing 4 respectively; Pinwheel 6 is connected with support 1, and the internal tooth of pinwheel 6 is meshed with the external tooth of cycloid wheel 5; Pivoted arm 7 is connected with output shaft 3, and pivoted arm 7 is made up of pin 8, column sleeve 9, and column sleeve 9 is evenly distributed with many pins 8, and pivoted arm 7 is connected with two eccentric wheels 5 by pin 8.Output shaft 3 is connected with column sleeve 9, and is integral type connection; Gap is had between pivoted arm 7 and cycloid wheel 5, the belleville spring 10 of the impact for alleviating axial force is provided with in gap, and butterfly spring 10 is placed on input shaft 2 place between pivoted arm 7 and cycloid wheel 5, pivoted arm 7 is fixed in belleville spring 10 one end, and the other end is fixed on cycloid wheel 5.
In use, when input shaft 2 rotates with capacity eccentric bearing 4, because cycloid wheel 5 external tooth is by the event of internal tooth restriction on pinwheel 6, the motion of cycloid wheel 5 becomes the plane motion that existing revolution has again rotation, when input shaft 2 rotates one week, capacity eccentric bearing 4 also rotates one week, cycloid wheel 5 turns over a tooth in opposite direction thus is slowed down, and relends and helps pivoted arm 7 and output shaft 3, by the low speed spinning motion of cycloid wheel 5 by pin 8 and column sleeve 9, pass to output shaft 3, thus obtain lower output speed; And the video disc spring 10 between pivoted arm 7 and cycloid wheel 5 effectively can slow down the axial impact force suffered by pivoted arm 7, thus ensure that the working life of pivoted arm 7.
The beneficial effects of the utility model are, go out to be provided with butterfly spring at output shaft, when cycloid is subject to axial impact, by the distortion of butterfly spring, alleviate the impact axially, thus increase the physical life of the part of speed reducer.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
