Technical Field

[0001] The utility model relates to the technical field of belt transmission of equipment, and particularly relates to a power synchronous transmission structure. Background Art

[0002] At present, in equipment transmission, belt transmission is particularly widely used. At the same time, belt parts (taking synchronous belts as an example) will involve problems such as wear, damage, and fracture, and need to be replaced or maintained. However, in current equipment, a synchronous shaft simultaneously penetrates a synchronous pulley and multiple belt pulleys. In such equipment, if the synchronous belt needs to be replaced or maintained, the parts connecting the belt pulleys on both sides also need to be disassembled. The disassembly and assembly are complicated, time-consuming, and laborious, and the connecting parts of the disassembled belt pulleys need to be repositioned. Content of the Utility Model

[0003] The purpose of the utility model is to provide a power synchronous transmission structure, which solves the technical problem of complicated disassembly and assembly of synchronous belts in the prior art. The preferred technical solutions provided by the utility model can produce many technical effects, which will be elaborated below.

[0004] To achieve the above purpose, the utility model provides the following technical solutions:

[0005] The power synchronous transmission structure provided by the utility model includes a driving transmission part, a first transmission shaft, a second transmission shaft, a first coupling, a second coupling, and a third coupling. A synchronous pulley of the driving transmission part is arranged on the first transmission shaft. One end of the first transmission shaft is connected to a first belt pulley through the first coupling, and the other end is connected to one end of the second transmission shaft through the second coupling. The other end of the second transmission shaft is connected to a second belt pulley through the third coupling.

[0006] Preferably, the distance between the first coupling and the synchronous pulley is less than the distance between the second coupling and the third coupling.

[0007] Preferably, the driving transmission part includes a driving motor, a driving belt pulley, a synchronous pulley, and a synchronous belt.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] To make the objectives, technical solutions and advantages of the present utility model clearer, the technical solutions of the present utility model will be described in detail below. Apparently, the described embodiments are only a part of the embodiments of the present utility model, rather than all of them. All other implementation manners obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts fall within the scope protected by the present utility model.

[0019] A specific embodiment of the present utility model provides a power synchronous transmission structure. As shown in the attached Figure 1 figure, it mainly includes a driving transmission part 1, a first transmission shaft 2, a second transmission shaft 3, a first coupling 4, a second coupling 5 and a third coupling 6.

[0020] Among them, the driving transmission part 1 is the main driving part and the transmission part, and there is a synchronous pulley 7 on the transmission part. The synchronous pulley 7 is arranged on the first transmission shaft 2 to drive the first transmission shaft 2 to rotate. One end of the first transmission shaft 2 is connected to the first belt pulley shaft 8 through the first coupling 4. The first belt pulley shaft 8 is used to connect with the belt pulley of the conveying device on one side. The other end of the first transmission shaft 2 is connected to one end of the second transmission shaft 3 through the second coupling 5. The other end of the second transmission shaft 3 is connected to the second belt pulley shaft 9 through the third coupling 6.

[0021] All of the first coupling 4, the second coupling 5 and the third coupling 6 can be loosened. During the actual disassembly and assembly process, it is necessary to first loosen the first coupling 4 and the third coupling 6, that is, just loosen the fastening bolts on the first coupling 4 and the third coupling 6. Then move the first coupling 4 and the third coupling 6 to the first belt pulley shaft 8 and the second belt pulley shaft 9 on both sides respectively. Then loosen the second coupling 5, that is, loosen the fastening screw of the second coupling 5 and move the second coupling 5 to the second transmission shaft 3. At this time, the second transmission shaft 3 can be removed. Then translate the first transmission shaft 2 in the direction of the second belt pulley shaft 9 so that the synchronous pulley 7 on the first transmission shaft 2 can be removed. At this time, the synchronous belt can be removed. Install the synchronous belt to be replaced and then install it back in reverse order according to the disassembly sequence to achieve rapid replacement of the synchronous belt. The components involved in this disassembly and assembly process are few and do not involve the belt pulley parts of the conveyor belts at both ends, which can greatly reduce the disassembly and assembly difficulty and save manpower.

[0022] In a specific embodiment of the present application, the distance between the first coupling 4 and the synchronous pulley 7 is less than the distance between the second coupling 5 and the third coupling 6. This ensures that the first transmission shaft 2 can be translated a sufficient distance in the direction of the second belt pulley shaft 9 to remove the synchronous pulley 7.

[0023] In some embodiments, the driving transmission part 1 includes a driving motor 10, a driving pulley 11, a synchronous pulley 7, and a synchronous belt 12. The driving pulley 11 is arranged on the output shaft of the driving motor 10, and the driving pulley 11 and the synchronous pulley 7 are connected by the synchronous belt 12.

[0024] The driving motor 10 is the main power output part. The driving pulley 11 is arranged on the driving motor 10, and the synchronous pulley 7 rotates driven by the driving pulley 11 and the synchronous belt 12. The rotation of the synchronous pulley 7 can drive the first pulley shaft 8 and the second pulley shaft 9 to rotate, thereby driving the conveyor belts on both sides to work.

[0025] In some embodiments, it further includes a mounting bracket 13. The driving motor 10 is arranged at one end of the mounting bracket 13, and the first transmission shaft 2 penetrates through the other end of the mounting bracket 13.

[0026] The mounting bracket 13 can be mounted on the equipment. The first transmission shaft 2 penetrates through the mounting bracket 13, which can enable the first transmission shaft 2 to operate stably.

[0027] In some embodiments, a connecting bracket 14 is arranged on the mounting bracket 13. An accommodation cavity 15 is formed between the connecting bracket 14 and the mounting bracket 13. The first transmission shaft 2 penetrates through the connecting bracket 14 and the mounting bracket 13, and the synchronous pulley 7 is located in the accommodation cavity 15.

[0028] The connecting bracket 14 can be a U-shaped structure, and the mounting bracket 13 can be a plate-shaped structure. The U-shaped opening of the connecting bracket 14 faces the mounting bracket 13. At this time, the accommodation cavity 15 is formed between the connecting bracket 14 and the mounting bracket 13. The connecting bracket 14 and the mounting bracket 13 provide a stable rotation environment for the first transmission shaft 2 and ensure the stable rotation of the synchronous pulley 7.

[0029] The first transmission shaft 2 is arranged on the connecting bracket 14 and the mounting bracket 13 through a bearing seat 16.

[0030] The bearing seat 16 and the first transmission shaft 2 can be connected in a transition fit or clearance fit manner, making it easy for the first transmission shaft 2 to translate.
