Abstract
The utility model discloses an outer-ring single-power multiple-supporting-point inner gear ring and outer gear ring transmission mechanism. The outer-ring single-power multiple-supporting-point inner gear ring and outer gear ring transmission mechanism comprises a gear ring, inner-ring teeth, a sun gear and a planet gear, wherein the outer-ring teeth are arranged on the outer outline of the gear ring, and two supporting wheels and a drive wheel are arranged outside the gear ring and are meshed with the outer-ring teeth. The outer-ring single-power multiple-supporting-point inner gear ring and outer gear ring transmission mechanism aims to meet special mechanical transmission requirements for a gear-ring outer single-point drive function, an outer-ring multiple-point driven function and an inner-ring driven function.
Description
Technical field
The utility model relates to gear transmission field, relates in particular to external toothing driving mechanism in the branched support point of a kind of outer ring single-power.
Background technique
Gear transmission is used widely in machine applications field, and it rotatablely moves to carry according to the engagement of metal-toothed and transmits kinetic energy, or changes moving direction.In the time of pair of metal tooth engagement driving, the transmission gear ring speed ratio that phoresys of carrying that rotatablely moves changes along with the variation of metal number of teeth engagement.In prior art, have the planetary gears of three planet wheels around a sun gear rotation, it is little, lightweight that this device has volume, and bearing capacity is high, long service life, smooth running, and noise is low.There is power dividing, the private characteristic of multiple tooth engagement, be widely used; But in actual machine application, sometimes need the outside single-point of gear ring to drive, outer ring multiple spot is driven simultaneously, inner ring is driven, at this moment just need to have special gear ring driving mechanism; For example, in Robot Design, precision engineering equipment, its transmission position needs the outside single-power of gear ring to drive sometimes, and outer ring multiple spot is driven simultaneously, inner ring is driven, and this planetary gears can not meet the demands.
Number of patent application: 200920178444.9, a kind of transmission gear ring is disclosed, comprise the exterior boss of eyelet, metal-toothed and circle, only have inner ring to have tooth, outer ring is mounting boss, can not meet special engineering application, at this moment just need to have special gear ring driving mechanism.
Model utility content
The purpose of this utility model is to provide external toothing driving mechanism in the branched support point of a kind of outer ring single-power, meets the outside single-point of gear ring and drives, the transmission effect that outer ring multiple spot is driven simultaneously, inner ring is driven.
For realizing above object, the technical solution adopted in the utility model is: external toothing driving mechanism in the branched support point of outer ring single-power, it comprises gear ring (2), internal ring gear (202), sun gear (3) and planet wheel (4), on described gear ring (2) external frame, is provided with outer ring tooth (201); There are 2 supporting wheels (1) and 1 driving wheel (5) in the outer installment of described gear ring (2), and are meshed with described outer ring tooth (201).
Further, described driving wheel (5) is 90 ° with the position angle of a supporting wheel (1), and described driving wheel (5) is 180 ° with the position angle of another supporting wheel (1).
The beneficial effects of the utility model: external toothing driving mechanism in the branched support point of the utility model outer ring single-power, there is planetary gears volume little, lightweight, bearing capacity is high, long service life, smooth running, the feature that noise is low; Meet the outside single-point of gear ring simultaneously and drive, the special mechanical transmission requirement that outer ring multiple spot is driven simultaneously, inner ring is driven.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Numerical reference described in figure is expressed as: 1, supporting wheel; 2, gear ring; 201, outer ring tooth; 202, internal ring gear; 3, sun gear; 4, planet wheel; 5, driving wheel.
Embodiment
In order to make those skilled in the art understand better the technical solution of the utility model; below in conjunction with accompanying drawing, the utility model is described in detail; the description of this part is only exemplary and explanatory, should not have any restriction to protection domain of the present utility model.
As shown in Figure 1, assembly relation of the present utility model is: it comprises gear ring 2, internal ring gear 202, sun gear 3 and planet wheel 4, on described gear ring 2 external frames, is provided with outer ring tooth 201; There is 1 and 1 driving wheel 5 of 2 supporting wheels in the outer installment of described gear ring 2, and be meshed with described outer ring tooth 201.
Preferably, the position angle of described driving wheel 5 and a supporting wheel 1 is 90 °, and described driving wheel 5 is 180 ° with the position angle of another supporting wheel 1.
When specific works, driving wheel 5 is driving wheel, drives gear ring 2 to rotate, and under the effect of the outer ring of gear ring 2 tooth 201,2 supporting wheels 1 rotate thereupon; Under the effect of the internal ring gear 202 of gear ring 2, three planet wheels 4 drive sun gear 3 to rotate; Drive the special mechanical transmission requirement that outer ring multiple spot is driven simultaneously, inner ring is driven thereby realize the outside single-point of gear ring.
It should be noted that, in this article, term " comprises ", " comprising " or its any other variant are intended to contain comprising of nonexcludability, thereby which key element the process, method, article or the equipment that make to comprise a series of key elements not only comprise, but also comprise other key elements of clearly not listing, or be also included as the intrinsic key element of this process, method, article or equipment.
Applied specific case herein principle of the present utility model and mode of execution are set forth, the explanation of above example is just for helping to understand method of the present utility model and core concept thereof.The above is only preferred implementation of the present utility model, should be understood that, due to the finiteness of literal expression, and objectively there is unlimited concrete structure, for those skilled in the art, not departing under the prerequisite of the utility model principle, can also make some improvement, retouching or variation, also above-mentioned technical characteristics can be combined by rights; These improve retouching, change or combination, or without improving, the design of model utility and technological scheme are directly applied to other occasion, all should be considered as protection domain of the present utility model.
