Description

Technical Field

[0001] This utility model relates to the field of transmission component technology, specifically a novel synchronous pulley. Background Technology

[0002] Synchronous pulleys are one of the tools that drive synchronous belts to rotate. They are generally made of materials such as steel, aluminum alloy, cast iron, and brass. Their inner holes can be round, D-shaped, or tapered. Synchronous belt pulley transmission consists of a closed annular rubber belt with equally spaced teeth on its inner circumference and corresponding pulleys. During operation, the toothed belt meshes with the tooth grooves of the pulleys to transmit motion and power.

[0003] A novel synchronous pulley, such as the one disclosed in patent publication number CN203604489U, includes an outer ring tooth with a hollow groove inside. An inner ring is installed within the hollow groove of the outer ring tooth. The inner ring has a limiting groove containing a ball bearing and a spring connected to it. There are 4-6 grooves, each containing a ball bearing. The limiting groove is an inclined "L" shape with an inclination angle of 23-38°. This design is structurally sound, can withstand large radial loads, and is not easily damaged.

[0004] However, to prevent the toothed belt from misaligning during long-term operation when the toothed belt and the synchronous pulley are driven together, the aforementioned equipment and existing synchronous pulleys typically have integrated synchronous pulley guards on both sides. However, this integrated design of the synchronous pulley guards and the synchronous pulley makes it difficult to replace if wear or damage occurs, which greatly reduces the service life of the synchronous pulley. Therefore, we propose a more convenient and practical synchronous pulley to meet the usage requirements. Utility Model Content

[0005] The purpose of this invention is to provide a novel synchronous pulley to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a novel synchronous wheel, comprising a connecting mechanism, a synchronous wheel body being provided on one side of the connecting mechanism, connecting grooves being provided on both sides of the synchronous wheel body, a plurality of equidistant teeth being fixedly connected to the outer wall of the synchronous wheel body, a plurality of equidistant heat dissipation holes being provided through one side of the synchronous wheel body, a fixing mechanism being provided on one side of the synchronous wheel body, the fixing mechanism comprising an outer baffle, a second threaded connecting ring being fixedly connected to one side of the outer baffle, and the second threaded connecting ring being threadedly connected to the connecting groove.

[0007] Furthermore, the connecting mechanism includes an inner baffle, a first threaded connecting ring is fixedly connected to one side of the inner baffle, the first threaded connecting ring and the connecting groove are threadedly connected, and a plurality of equidistant heat dissipation grooves are opened on one side of the inner baffle, the heat dissipation grooves and heat dissipation holes are connected to each other.

[0008] Furthermore, a plurality of equidistant clamping plates are fixedly connected to one side of the inner baffle, and a rotating ring is threadedly connected to the outer wall of the clamping plates.

[0009] Furthermore, a plurality of equidistant fixing blocks are fixedly connected to one side of the outer baffle, and a through hole is opened on one side of the fixing block, with a screw threaded into the through hole.

[0010] Furthermore, a rotating block is fixedly connected to one end of the screw, and a fixed ring is rotatably connected to the other end.

[0011] Furthermore, a clamping ring is fixedly connected to one side of the fixing ring, and a stop ring is fixedly connected to one side of the clamping ring.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This new type of synchronous pulley, through the setting of a connecting mechanism and a fixing mechanism, allows for initial fixing during use. When the synchronous pulley body needs to be installed, the outer baffle is threadedly connected to the connecting groove on the other side of the synchronous pulley body via a second threaded connecting ring. Then, the rotating block on the fixing block is manually operated to adjust the tightness of the screw. The screw drives the fixing ring and clamping ring to apply pressure to the drive shaft or transmission components, and the stop ring ensures that the synchronous pulley body and the shaft fit tightly, preventing loosening. Disassembly is performed through the same steps. This device allows the old synchronous pulley to be removed and the new synchronous pulley to be tightened without disassembling the entire transmission system, simply by loosening the threads. This significantly reduces downtime, improves production efficiency, and is highly practical and suitable for widespread adoption.

[0014] Meanwhile, the connecting mechanism can eliminate installation gaps, prevent axial movement or loosening during transmission, and ensure smooth power transmission. Attached Figure Description

[0020] 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.

[0021] Synchronous pulleys are required in the use of transmission equipment. The synchronous pulley provided by this utility model is specifically designed for use in transmission equipment. When installing, ensure the coaxiality of the synchronous pulley and the transmission shaft to avoid transmission instability or damage due to improper installation. During use, the wear condition of the synchronous pulley should be checked regularly. If the wear is severe, replace it in time to ensure the stability and accuracy of the transmission. Do not use the synchronous pulley under overload or harsh environments to avoid damage to the synchronous pulley or transmission failure. The synchronous pulley may become loose during long-term use. Please check and tighten the relevant connecting parts regularly to ensure the stability of the synchronous pulley.

[0022] like Figures 1-4 As shown, this utility model provides a technical solution: a novel synchronous pulley, including a connecting mechanism 1, a synchronous pulley body 2 is provided on one side of the connecting mechanism 1, connecting grooves 3 are provided on both sides of the synchronous pulley body 2, a plurality of equidistant teeth 4 are fixedly connected to the outer wall of the synchronous pulley body 2, a plurality of equidistant heat dissipation holes 5 are provided through one side of the synchronous pulley body 2, a fixing mechanism 6 is provided on one side of the synchronous pulley body 2, the fixing mechanism 6 includes an outer baffle 601, a second threaded connecting ring 602 is fixedly connected to one side of the outer baffle 601, and the second threaded connecting ring 602 and the connecting groove 3 are threadedly connected.

[0023] like Figure 3 As shown, the connecting mechanism 1 includes an inner baffle 101. A first threaded connecting ring 102 is fixedly connected to one side of the inner baffle 101. The first threaded connecting ring 102 and the connecting groove 3 are threadedly connected. A plurality of equidistant heat dissipation grooves 103 are opened on one side of the inner baffle 101. The heat dissipation grooves 103 and the heat dissipation holes 5 are connected to each other. A plurality of equidistant clamping plates 104 are fixedly connected to one side of the inner baffle 101. A rotating ring 105 is threadedly connected to the outer wall of the clamping plate 104.

[0024] It should be noted that during use and installation, the inner baffle 101 is threadedly connected to the connecting groove 3 on one side of the synchronous pulley body 2 via the first threaded connecting ring 102. At the same time, the heat dissipation groove 103 on the inner baffle 101 is connected to the heat dissipation hole 5 of the synchronous pulley body 2 to form a heat dissipation channel and improve heat dissipation efficiency. Finally, the clamping force is adjusted by rotating the rotating ring 105 to fix the drive shaft or transmission component with the clamping plate 104. The connecting mechanism 1 can eliminate the installation gap, avoid axial movement or loosening during transmission, and ensure the smoothness of power transmission.

[0025] like Figure 4 As shown, a plurality of equidistant fixing blocks 603 are fixedly connected to one side of the outer baffle 601. A through hole is opened on one side of the fixing block 603, and a screw 604 is threaded into the through hole. A rotating block 605 is fixedly connected to one end of the screw 604, and a fixing ring 606 is rotatably connected to the other end. A clamping ring 607 is fixedly connected to one side of the fixing ring 606, and a stop ring 608 is fixedly connected to one side of the clamping ring 607.

[0026] It should be noted that when the synchronous pulley body 2 needs to be installed, the outer baffle 601 is threadedly connected to the connecting groove 3 on the other side of the synchronous pulley body 2 through the second threaded connecting ring 602, forming a preliminary fixation. Then, the rotating block 605 on the fixing block 603 is manually operated to adjust the tightness of the screw 604. The screw 604 drives the fixing ring 606 and the clamping ring 607 to apply pressure to the drive shaft or transmission components, and through the stop ring 608, it ensures that the synchronous pulley body 2 is tightly fitted to the shaft to prevent loosening. The same steps are used for disassembly. The fixing mechanism 6 can adapt to drive shafts or loads of different diameters to ensure that the synchronous pulley is firmly fixed in both the axial and radial directions.

[0027] During use, during installation, the inner baffle 101 is threadedly connected to the connecting groove 3 on one side of the synchronous pulley body 2 via the first threaded connecting ring 102. At the same time, the heat dissipation groove 103 on the inner baffle 101 communicates with the heat dissipation hole 5 on the synchronous pulley body 2, forming a heat dissipation channel to improve heat dissipation efficiency. Finally, the clamping force is adjusted by rotating the rotating ring 105 to fix the drive shaft or transmission component with the clamping plate 104. Meanwhile, the outer baffle 601 is threadedly connected to the connecting groove 3 on the other side of the synchronous pulley body 2 via the second threaded connecting ring 602, forming a preliminary fixation. Then, the rotating block 605 on the fixing block 603 is manually operated to adjust the tightness of the screw 604. The screw 604 drives the fixing ring 606 and the clamping ring 607 to apply pressure to the drive shaft or transmission component, and the stop ring 608 ensures that the synchronous pulley body 2 and the shaft fit tightly to prevent loosening. This device can remove the old synchronous pulley and tighten the new synchronous pulley without disassembling the entire transmission system, simply by loosening the threads, significantly reducing downtime and improving production efficiency.
