Abstract
The utility model discloses a stable synchronous pulley with check rings. The stable synchronous pulley comprises a pulley body (1), the check rings (2), gear teeth (3) and V-shaped grooves (4). The gear teeth (3) are evenly distributed on the side face of the pulley body (1) in the longitudinal direction. The V-shaped grooves (4) are formed in the circumferences of the two end faces of the pulley body (1). The check rings (2) are arranged on the upper surface of the pulley body (1) and the lower surface of the pulley body (1) respectively and connected into the V-shaped grooves (4) in a spinning and riveting mode. Through the structure, the check rings are connected into the V-shaped grooves in the riveting mode and fixed to the pulley body in a transition matched mode, fixation is firmer, and running is more stable.
Description
Technical field
The utility model relates to belt wheel, is specifically related to the synchronous pulley of stable type band back-up ring.
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, 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 synchronous pulley body of producing in the past and the riveted of back-up ring, at the several points of junction riveting (normally uniform 4 points on circumference) with chisel, the riveted of some like this, only to be fixed back-up ring by carving the flow of metal at position on synchronous pulley body, its firm intensity is difficult to guarantee the functional reliability of synchronous pulley, if synchronous pulley body and back-up ring are Spielpassung, be just more difficult to ensure card riveting quality and intensity.In use, back-up ring is very easily subject to the extruding of Timing Belt side to synchronous pulley body, and extruding will make back-up ring be easy to come off for a long time, and this phenomenon will have a strong impact on normal operation and the functional reliability of synchronous pulley body.
Model utility content
The utility model has overcome the deficiencies in the prior art, and the synchronous pulley of stable type band back-up ring is provided, and back-up ring is entered V-groove and adopted the mode of transition fit to be fixed on belt wheel body by riveted, fixing more firm, moves more stable.
For solving above-mentioned technical problem, the utility model is by the following technical solutions: the synchronous pulley of stable type band back-up ring, comprise belt wheel body, back-up ring, the gear teeth and V-groove, on the longitudinal direction of described belt wheel body side, be evenly distributed with many gear teeth, on the both ends of the surface circumference of belt wheel body, be provided with a plurality of V-grooves; The upper and lower surface of described belt wheel body is provided with back-up ring, and back-up ring spinning riveted enters in V-groove.
Further, the angular range of described V-groove is between 60 °-90 °.
Further, the groove depth scope of described V-groove is between 1-2mm.
Further, the radius size of described V-groove upper surface open is between 2.5-3.5mm.
Further, a plurality of V-grooves on described belt wheel body both ends of the surface circumference are uniformly distributed.
What further, described belt wheel body was hollow is cylindrical.
Compared with prior art, the beneficial effects of the utility model are:
1, the utility model is by being provided with V-groove, and back-up ring spinning riveted, in the process on belt wheel, extruding V-groove makes V-groove distortion, thereby makes highly stable being fixed on belt wheel of back-up ring.
2, belt wheel body of the present utility model is transition fit with coordinating of back-up ring, back-up ring riveted enters V-groove and adopts the mode of transition fit to be fixed on belt wheel body, back-up ring is not subject to the extruding of Timing Belt side, thereby back-up ring is not easy to come off, guarantee the stable operation of belt wheel body, functional reliability is strengthened.
3, the angular range of V-groove of the present utility model is arranged between 60 ° to 90 ° and can reaches best fixed effect.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the sectional view of belt wheel body in Fig. 1.
In figure, reference character is expressed as: 1, belt wheel body; 2, back-up ring; 3, the gear teeth; 4, V-groove.
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 1-2, the utility model comprises belt wheel body 1, back-up ring 2, the gear teeth 3 and V-groove 4.On the longitudinal direction of belt wheel body 1 side of the present embodiment, be evenly distributed with many gear teeth 3, on the both ends of the surface circumference of belt wheel body 1, be provided with a plurality of V-grooves 4, the angular range of V-groove 4 is between 60 °-90 °, the groove depth scope of V-groove 4 is between 1-2mm, and the radius size of V-groove 4 upper surface open is between 2.5-3.5mm.The upper and lower surface of the belt wheel body 1 of the present embodiment is provided with back-up ring 2, and back-up ring 2 spinning riveteds enter in V-groove 4.A plurality of V-grooves 4 on belt wheel body 1 both ends of the surface circumference are uniformly distributed, and what belt wheel body 1 was hollow is cylindrical.
Back-up ring spinning riveted enters V-groove and the mode by transition fit is fixed on the two ends circumference of belt wheel body, avoids back-up ring to be subject to the extruding of Timing Belt side, and causes the situation that back-up ring comes off to occur, and guarantees normal operation and the functional reliability of belt wheel body.
Just can realize this model utility as mentioned above.
