Abstract
The utility model discloses a stable type synchronous pulley which comprises a pulley body (1), check rings (2), gear teeth (3) and protruding riveting pieces (4). The gear teeth are evenly distributed on the side face of the pulley body (1) in the longitudinal direction, and the circumferences of the two end faces of the pulley body (1) are respectively provided with one circle of protruding riveting piece (4); the check rings (2) are riveted in the circles of protruding riveting pieces (4) arranged on the two end faces of the pulley body (1). According to the structure, the whole check rings are riveted to the pulley body through the protruding riveting pieces and fixation is more stable.
Description
Technical field
The utility model relates to synchronous pulley field, is specifically related to a kind of stable type 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, 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, for the fixing structure of segmentation, adopt and severally name a person for a particular job back-up ring riveting on belt wheel body, the riveted of some like this, only to be fixed back-up ring by carving the flow of metal at position on belt wheel body, its firm intensity is difficult to guarantee belt wheel body functional reliability, if belt wheel body and back-up ring are Spielpassung, is just more difficult to ensure card riveting quality and intensity.In use, the poor stability between back-up ring and belt wheel body, easily comes off belt wheel body, affects the work in later stage.
Model utility content
The utility model has overcome the deficiencies in the prior art, and a kind of stable type synchronous pulley is provided, and back-up ring is all riveted on belt wheel body by this circle convex riveting parts, fixes more stablely.
For solving above-mentioned technical problem, the utility model is by the following technical solutions: a kind of stable type synchronous pulley, comprise belt wheel body, back-up ring, the gear teeth and convex riveting parts, 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 respectively arranged with a circle convex riveting parts; Described back-up ring is riveted in the circle convex riveting parts arranging in belt wheel body both ends of the surface.
On described convex riveting parts, each position horizontal width equates.
On described convex riveting parts, each position is longitudinally highly equal.
Convex riveting parts in the both ends of the surface of described belt wheel body is symmetrical.
Many the gear teeth on described belt wheel body equidistantly distribute.
Compared with prior art, the beneficial effects of the utility model are:
1, the utility model changes riveted form between the back-up ring of segmental structure formula in the past and belt wheel body to adopt the whole convex riveting parts of a circle to carry out the riveted between back-up ring and belt wheel body into, the riveting portion that back-up ring all protrudes by this circle is riveted on belt wheel body, fixes more stablely.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation 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, convex riveting parts.
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 convex riveting parts 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 respectively arranged with a circle convex riveting parts 4, convex riveting parts 4 in the both ends of the surface of belt wheel body 1 is symmetrical, and many gear teeth 3 on belt wheel body 1 equidistantly distribute.The back-up ring 2 of the present embodiment is riveted in the circle convex riveting parts 4 arranging in belt wheel body 1 both ends of the surface, and on convex riveting parts 4, each position horizontal width equates, on convex riveting parts 4, each position is longitudinally highly equal.
Riveted form between the back-up ring of segmental structure formula in the past and belt wheel body is changed into and adopts the whole convex riveting parts of a circle to carry out the riveted between back-up ring and belt wheel body, the riveting portion that back-up ring all protrudes by this circle is riveted on belt wheel body, fixes more stablely.
Just can realize this model utility as mentioned above.
