Abstract
Description
Technical Field
[0001] This utility model belongs to the field of synchronous belt technology, specifically relating to a synchronous belt with a splicing structure. Background Technology
[0002] In industrial transmission systems, synchronous belts with splicing structures are widely used in various types of machinery due to their installation flexibility and cost advantages. However, after the splicing operation is completed, the areas near the two ends of these synchronous belts lack effective fixing and locking structures.
[0003] From a mechanical perspective, synchronous belts continuously bear the tension from the transmission system during normal operation. Because the mating ends lack a stable fixing mechanism, the tension continuously concentrates at the joint, causing the originally tightly fitted surfaces to gradually separate, resulting in noticeable gaps. Common industrial applications such as metal shavings, dust particles, and fibrous impurities are forcibly drawn into these gaps during opening and closing. The entry of these foreign objects directly disrupts the force balance at the mating ends of the synchronous belt. The originally evenly distributed tension becomes a localized stress concentration point due to the obstruction of the foreign object, drastically increasing the load on the synchronous belt and introducing instability into its operation. Utility Model Content
[0004] The purpose of this invention is to provide a synchronous belt with a splicing structure, aiming to solve the problem that when the mating ends lack a stable fixing mechanism, the tensile force continuously concentrates at the splice, causing the originally tightly fitted mating surfaces to gradually separate, resulting in a noticeable gap. Common industrial applications such as metal shavings, dust particles, and fibrous impurities can be forcibly drawn into this gap during its opening and closing motion. The entry of foreign objects directly disrupts the force balance at the mating ends of the synchronous belt. The originally evenly distributed tensile force becomes localized stress concentration points due to the obstruction of foreign objects, drastically increasing the load on the synchronous belt and introducing instability into its operation.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a synchronous belt with a splicing structure, comprising a synchronous belt, wherein a set of racks are integrally arranged at equal intervals on the inner wall of the synchronous belt, a first mating end is integrally connected to one end of the synchronous belt, a second mating end is integrally connected to the other end of the synchronous belt, two side strips are integrally and symmetrically installed on one end of the second mating end, and a center strip is integrally installed on the center end of the first mating end;
[0006] The first and second mating ends are connected by a center strip and a side strip, and the center strip and the side strip are spliced by steel pins. A pressure strip is integrally connected to the outer wall of the first mating end on both sides of the center strip. A bottom strip is provided below the pressure strip. One end of the bottom strip is integrally connected to the outer wall of the first mating end. One end of the side strip is inserted into the gap between the corresponding pressure strip and the bottom strip.
[0007] In order to enable the locking pin to smoothly connect with the hollow pin, as a synchronous belt with splicing structure of this utility model, preferably, three hollow pins are integrally installed at equal intervals at the bottom of the pressure strip, the inner wall of the hollow pin is provided with a spiral groove, and the top opening of the hollow pin extends to the surface of the pressure strip.
[0008] In order to ensure that the locking pin accurately connects and locks with the bottom pin after passing through the hollow pin, as a synchronous belt with splicing structure of this utility model, preferably, three bottom pins are integrally installed at equal intervals on the surface of the bottom strip, and the top of each bottom pin is aligned with the bottom of a hollow pin.
[0009] As a synchronous belt with a splicing structure according to this utility model, preferably, a locking post is installed through the top of the pressure strip, and the bottom of the locking post spirally penetrates the hollow post and is spirally connected to the inside of the bottom post.
[0010] In order to enable one end of the side strip to be connected to the first mating end through the pressure strip and the bottom strip, as a synchronous belt with splicing structure of this utility model, preferably, a groove is opened on the upper and lower sides of one end of the side strip, and three through holes are equally spaced through each groove. Each side strip is inserted into two pressure strips and bottom strips of the same group through the groove, and the hollow column at the bottom of the pressure strip and the bottom column on the surface of the bottom strip are respectively inserted into the upper and lower ends of the corresponding through holes.
[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] After the first and second mating ends are connected via the center strip and side strips, the two side strips are positioned at one end of the first mating end on either side of the center strip. Then, the pressure strip and bottom strip are moved so that one end of the side strip is inserted into the gap between them. Next, the hollow post and bottom post are inserted into the through hole, and finally, the locking post is installed between them. This creates a secure mating structure between one end of the side strip and the first mating end, preventing excessive gaps between the side strips and the first mating end due to tension when the timing belt is operating. This prevents material jamming caused by excessive gaps between the side strips and the first mating end, improving the stability of the timing belt during operation. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] Please see Figure 1-4 The present invention provides the following technical solution: a synchronous belt with a splicing structure, including a synchronous belt 1, a set of racks 2 are integrally arranged at equal intervals on the inner wall of the synchronous belt 1, a first docking end 3 is integrally connected to one end of the synchronous belt 1, a second docking end 4 is integrally connected to the other end of the synchronous belt 1, two side strips 6 are integrally and symmetrically installed on one end of the second docking end 4, and a center strip 5 is integrally installed on the center end of the first docking end 3;
[0021] When using the synchronous belt 1, an anti-adhesion coating can be applied to the outer wall. This coating is used to prevent foreign objects from sticking to the synchronous belt 1, effectively isolating the surface of the synchronous belt 1 from contact with foreign objects, reducing the adhesion of dust, oil and other substances, and maintaining the cleanliness of the synchronous belt 1 surface.
[0022] The first mating end 3 and the second mating end 4 are connected by a center strip 5 and a side strip 6, and the center strip 5 and the side strip 6 are spliced by steel pins. A pressure strip 7 is integrally connected to the outer wall of the first mating end 3 on both sides of the center strip 5. A bottom strip 9 is provided below the pressure strip 7. One end of the bottom strip 9 is integrally connected to the outer wall of the first mating end 3, and one end of the side strip 6 is inserted into the gap between the corresponding pressure strip 7 and the bottom strip 9.
[0023] Preferably, the bottom of the pressure strip 7 is integrally installed with three hollow columns 71 at equal intervals. The inner wall of the hollow columns 71 is provided with a spiral groove, and the top opening of the hollow columns 71 extends to the surface of the pressure strip 7.
[0024] Preferably, three base posts 91 are integrally installed at equal intervals on the surface of the base strip 9, with the top of each base post 91 aligned with the bottom of a hollow post 71.
[0025] In practical use, after the side strip 6 is installed between the pressure strip 7 and the bottom strip 9, the flipping of the pressure strip 7 and the bottom strip 9 is released. The pressure strip 7 and the bottom strip 9 will reset, thereby allowing the pressure strip 7 and the bottom strip 9 to snap into the groove 61;
[0026] At the same time, the hollow column 71 at the bottom of the pressure strip 7 and the bottom column 91 on the surface of the bottom strip 9 will be inserted into the interior of the through hole 62.
[0027] Preferably, a locking post 8 is installed through the top of the pressure strip 7, and the bottom of the locking post 8 spirally penetrates the hollow post 71 and is spirally connected to the inside of the bottom post 91.
[0028] In practical use, after the pressure strip 7 and bottom strip 9 are connected to the side strip 6, the locking pin 8 is inserted from the top of the pressure strip 7 so that it passes through the hollow pin 71 and connects with the bottom pin 91. In this way, the pressure strip 7 and bottom strip 9 can maintain a firm connection structure with the side strip 6, thereby reducing the large gap that may be created when the synchronous belt 1 is working, which is pulled between the first connection end 3 and the connection end of the side strip 6.
[0029] Preferably, a groove 61 is provided on the upper and lower sides of one end of the side strip 6, and three through holes 62 are provided at equal intervals on each groove 61. Each side strip 6 is inserted into two pressure strips 7 and bottom strips 9 of the same group through the groove 61, and the hollow column 71 at the bottom of the pressure strip 7 and the bottom column 91 on the surface of the bottom strip 9 are respectively inserted into the upper and lower ends of the corresponding through holes 62.
[0030] In practical use, after the first mating end 3 and the second mating end 4 are mated through the center strip 5 and the side strip 6, the two side strips 6 are also positioned at one end of the first mating end 3 on both sides of the center strip 5. Then, the pressure strip 7 and the bottom strip 9 are moved so that one end of the side strip 6 is inserted into the gap between the pressure strip 7 and the bottom strip 9. Then, the hollow column 71 and the bottom column 91 are inserted into the through hole 62, and finally, the locking column 8 is installed between the hollow column 71 and the bottom column 91. In this way, one end of the side strip 6 can form a tight mating structure with the first mating end 3, so that when the synchronous belt 1 is working, the gap between the side strip 6 and the first mating end 3 will not be too large due to tension, thus preventing the jamming phenomenon caused by the excessive gap between the side strip 6 and the first mating end 3, and improving the stability of the synchronous belt 1 during operation.
[0031] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
