Abstract
The invention discloses a multi-direction transmission synchronous pulley which comprises a first pulley body (1), a second pulley body (2), a first retaining ring (3), a second retaining ring (4) and a third retaining ring (5). The first retaining ring (3) and the second retaining ring (4) are respectively connected to two ends of the first pulley body (1) in a spinning manner. The second retaining ring (4) and the third retaining ring (5) are respectively connected to two ends of the second pulley body (2) in a spinning manner. The second retaining ring (4) is located between the first retaining ring (3) and the third retaining ring (5). By the structure, bi-directional transmission can be realized, and transmission direction diversity is achieved.
Description
Technical field
The present invention relates to the synchronous pulley field, be specifically related to the polydirectional transmission synchronous pulley.
Background technique
Closed ring adhesive tape and corresponding belt wheel that synchronous belt pulley transmission is provided with equidistant tooth by an interior perimeter surface are formed.During motion, be meshed with the teeth groove of belt wheel with tooth and transmit motion and power, be a kind of engagement driving, thereby there are the various characteristics of gear transmission, chain transmission and flat belt driving.Be widely used in the fields such as automobile, weaving, printing packaging equipment, needling equipment, office equipment, laser engraving equipment, tobacco, financial machine and tool, light of stage, communication food machinery, medical machinery, steel machinery, petrochemical industry, instrument and apparatus, various precision machine tools.The riveted of synchronous pulley body and back-up ring is at the several points of junction riveting (normally uniform 4 points on circumference), by the synchronous pulley body, by the flow of metal at engraving tool position, being fixed back-up ring, to guarantee the functional reliability of synchronous pulley with chisel.The synchronous pulley used now can only carry out single-direction transmission, and direction of transfer is single, can not realize multi-direction transmission or synchronous the transmission simultaneously, and using scope is restricted, and the field higher for ask for something can't meet the production actual demand.
Summary of the invention
The present invention has overcome the deficiencies in the prior art, and the polydirectional transmission synchronous pulley is provided, and is provided with the first belt wheel body and the second belt wheel body, can realize Bidirectional driving, and transmission direction is more diversified.
For solving above-mentioned technical problem, the present invention is by the following technical solutions: the polydirectional transmission synchronous pulley, comprise the first belt wheel body, the second belt wheel body, the first back-up ring, the second back-up ring and the 3rd back-up ring, described the first back-up ring and the second back-up ring spinning respectively are connected to the two ends of the first belt wheel body; Described the second back-up ring and the 3rd back-up ring spinning respectively are connected to the two ends of the second belt wheel body; Described the second back-up ring is between the first back-up ring and the 3rd back-up ring.
Further, be provided with two symmetrical positioning holes on the circumference of described the 3rd back-up ring.
Further, described the first back-up ring, the second back-up ring and the 3rd back-up ring are parallel to each other.
Further, described the first back-up ring and the second back-up ring equal and opposite in direction.
Further, described the first belt wheel body and the second belt wheel body size equate.
Further, the height of described the 3rd back-up ring is greater than the height of the first back-up ring.
Compared with prior art, the invention has the beneficial effects as follows:
1, the present invention is provided with the first belt wheel body and the second belt wheel body, and two-part selectivity work according to actual needs both can Bidirectional driving, also can select unidirectional delivery, and transmission direction is more diversified, and practicability is stronger.
2, the present invention is provided with special positioning hole on the circumference of third gear circle, and this device is carried out to multi-faceted location, makes the transmission of this device more firm, the phenomenon of displacement can in transmission process, not occur.
The accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
In figure, reference character is expressed as respectively: 1, the first belt wheel body; 2, the second belt wheel body; 3, the first back-up ring; 4, the second back-up ring; 5, the 3rd back-up ring; 6, positioning hole.
Embodiment
Below in conjunction with accompanying drawing, the present invention is further elaborated, and embodiments of the invention are not limited to this.
Embodiment:
As shown in Figure 1, the present invention includes the first belt wheel body 1, the second belt wheel body 2, the first back-up ring 3, the second back-up ring 4 and the 3rd back-up ring 5, the first belt wheel bodies 1 and the second belt wheel body 2 equal and opposite in directions.First back-up ring 3 of the present embodiment and the second back-up ring 4 spinning respectively are connected to the two ends of the first belt wheel body 1; The second back-up ring 4 and the 3rd back-up ring 5 spinning respectively are connected to the two ends of the second belt wheel body 2.Second back-up ring 4 of the present embodiment is between the first back-up ring 3 and the 3rd back-up ring 5, be provided with two symmetrical positioning holes 6 on the circumference of the 3rd back-up ring 5, the first back-up ring 3, the second back-up ring 4 and the 3rd back-up ring 5 are parallel to each other, the first back-up ring 3 and the second back-up ring 4 equal and opposite in directions, the height of the 3rd back-up ring 5 is greater than the height of the first back-up ring 3.
The first belt wheel body and the second belt wheel body link together by the second back-up ring, become as a whole, externally under the drive of driving force, realize Bidirectional driving.In addition, also can be according to actual needs, selectivity work, also can realize unidirectional delivery, and transmission direction is more diversified, and practicability is stronger.Be provided with positioning hole on this device, transmission is more firm, and direction is not easy to occur skew.
Just can realize this invention as mentioned above.
