Abstract
The utility model discloses a locking type synchronous pulley. The locking type synchronous pulley comprises a pulley body (1), a check ring (2), a fastening ring (3) and positioning holes (4). The two ends of the pulley body (1) are connected with the check ring (2) and the fastening ring (3) respectively in a rotating and pressing mode. The positioning holes (4) are formed in the fastening ring (3) in the radial direction. A through hole (5) is formed in the center position of the fastening ring (3). The through hole (5) and a hollow structure of the pulley body (1) are connected to form an integral structure. According to the structure, by arranging the special fastening ring and forming the positioning holes and the through hole in the fastening ring, a center shaft which is inserted into the pulley body in a penetrating mode is locked in multiple directions, and the pulley body and the center shaft are prevented from being disengaged.
Description
Technical field
The utility model relates to transmission device field, is specifically related to lock type synchronous pulley.
Background technique
Closed ring adhesive tape and corresponding belt wheel that belt wheel transmission is provided with equidistant tooth by an interior perimeter surface are formed.During motion, with tooth, be meshed with the teeth groove of belt wheel and transmit motion and power, be a kind of engagement driving, thereby there are the various features 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 being fixed back-up ring by the flow of metal at engraving tool position on synchronous pulley body, to guarantee the functional reliability of synchronous pulley with chisel.The synchronous pulley using now does not all arrange special in locking the structure of central shaft, only by the back-up ring being connected on belt wheel body, carry out auxiliary positioning, and back-up ring general thickness is little, can only compare general fixing, can not reach the locking to the high requirement of central shaft.
Model utility content
The utility model has overcome the deficiencies in the prior art, lock type synchronous pulley is provided, is provided with special fastening ring, on fastening ring, be provided with positioning hole and through hole, reach the central shaft that multi-faceted locking interts on belt wheel body, avoid belt wheel body separated with central shaft.
For solving above-mentioned technical problem, the utility model by the following technical solutions: lock type synchronous pulley, comprise belt wheel body, back-up ring, fastening ring and positioning hole, the two ends of described belt wheel body respectively spinning connect back-up ring and fastening ring; A plurality of positioning holes are upwards installed in the footpath of described fastening ring, and the central position of fastening ring is provided with through hole, the structure that is connected as a single entity of the hollow structure on through hole and belt wheel body.
Further, in described positioning hole, be provided with uniform screw thread.
Further, the diameter of described back-up ring and the equal diameters of fastening ring.
Further, the height of described back-up ring is less than the height of fastening ring.
Further, a plurality of positioning holes that upwards install in the footpath of described fastening ring are symmetrical.
Compared with prior art, the beneficial effects of the utility model are:
1, the utility model arranges special fastening ring on belt wheel body, on fastening ring, be also provided with positioning hole and through hole matches, after this device inserts central shaft, can realize the multi-direction locking to belt wheel central shaft, recycle external fixation pin simultaneously and be fixed and between central shaft and belt wheel body, be not easy to occur running sliding phenomenon.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure, reference character is expressed as: 1, belt wheel body; 2, back-up ring; 3, fastening ring; 4, positioning hole; 5, through hole.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further elaborated, embodiment of the present utility model is not limited to this.
Embodiment:
As shown in Figure 1, the utility model comprises belt wheel body 1, back-up ring 2, fastening ring 3 and positioning hole 4.The two ends of the belt wheel body 1 of the present embodiment respectively spinning connect back-up ring 2 and fastening ring 3, the equal diameters of the diameter of back-up ring 2 and fastening ring 3, the height of back-up ring 2 is less than the height of fastening ring 3, a plurality of positioning holes 4 that upwards install in the footpath of fastening ring 3 are symmetrical, are provided with uniform screw thread in positioning hole 4.A plurality of positioning holes 4 are upwards installed in the footpath of the fastening ring 3 of the present embodiment, and the central position of fastening ring 3 is provided with through hole 5, through hole 5 and hollow structure on belt wheel body 1 structure that is connected as a single entity.
During use, central shaft is inserted in the hollow structure of belt wheel body, the positioning hole upwards arranging by fastening ring footpath utilizes bolt to be fixed.And the thickness that fastening ring arranges wants thick a lot of with respect to back-up ring, when being fixed, can utilize longer bolt to be fixed, also the situation that there will not be fastening ring to be damaged by pressure occurs, and the locking between belt wheel body and central shaft is more firm, is not easy to occur running sliding phenomenon.
Just can realize this model utility as mentioned above.
