Abstract
The invention discloses a belt pulley high in stability. The belt pulley comprises a belt pulley body (1), retaining rings (2), a plurality of gear teeth (3) and a plurality of V-shaped grooves (4). The gear teeth (3) are evenly and longitudinally distributed on the side face of the belt pulley body (1), the V-shaped grooves (4) are formed in the circumference of two end faces of the belt pulley body (1), the upper surface and the lower surface of the belt pulley body (1) are respectively provided with a retaining ring (2), and the retaining rings (2) are riveted into the V-shaped grooves (4) in a spinning manner. According to the arrangement that the retaining rings are riveted into the V-shaped grooves in a spinning manner and are fixed onto the belt pulley body in a transition fit manner, wheels can be firmly fixed, and operation is stable.
Description
Technical field
The present invention relates to belt wheel, be specifically related to the belt wheel that stability is high.
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 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 by the synchronous pulley body, by the flow of metal at engraving tool position, being fixed back-up ring, its firm intensity is difficult to guarantee the functional reliability of synchronous pulley, if synchronous pulley body and back-up ring are Spielpassung, just more be difficult to ensure card riveting quality and intensity.In use, back-up ring very easily is subject to the extruding of Timing Belt side to the 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.
Summary of the invention
The present invention has overcome the deficiencies in the prior art, and the belt wheel that stability is high is provided, and back-up ring advances V-groove and adopts the mode of transition fit to be fixed on the belt wheel body by riveted, fixing more firm, moves more stable.
For solving above-mentioned technical problem, the present invention is by the following technical solutions: the belt wheel that stability is high, comprise belt wheel body, back-up ring, the gear teeth and V-groove, be evenly distributed with many gear teeth on the longitudinal direction of described belt wheel body side, 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 advances 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 invention has the beneficial effects as follows:
1, the present invention is by being provided with V-groove, and back-up ring spinning riveted, in the process on belt wheel, the extruding V-groove makes the V-groove distortion, thereby makes highly stable being fixed on belt wheel of back-up ring.
2, belt wheel body of the present invention is transition fit with coordinating of back-up ring, the back-up ring riveted advances V-groove and adopts the mode of transition fit to be fixed on the 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 invention is arranged between 60 ° to 90 ° and can reaches best fixed effect.
The accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
The sectional view that Fig. 2 is belt wheel body in Fig. 1.
In figure, reference character is expressed as respectively: 1, belt wheel body; 2, back-up ring; 3, the gear teeth; 4, V-groove.
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 1-2, the present invention includes belt wheel body 1, back-up ring 2, the gear teeth 3 and V-groove 4.Be evenly distributed with many gear teeth 3 on the longitudinal direction of belt wheel body 1 side of the present embodiment, be provided with a plurality of V-grooves 4 on the both ends of the surface circumference of belt wheel body 1, 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 advance 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 advances 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 the situation that causes back-up ring to come off occurs, and guarantees normal operation and the functional reliability of belt wheel body.
Just can realize this invention as mentioned above.
