[0017] 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.

[0018] To solve the problem of how to effectively position and adjust the technology, such as Figure 1-5 As shown, the following preferred technical solutions are provided: An adjustable torque sprocket assembly includes a drive sprocket 1 and a torque adjustment component 2. The drive sprocket 1 has a hole in its middle, and a torque adjustment ring 3 is engaged in the middle of the drive sprocket 1. The torque adjustment component 2 is fixedly connected to one side of the torque adjustment ring 3. The torque adjustment component 2 includes a spline shaft 201. A pressure spring 202 is sleeved on the surface of the spline shaft 201. An adjustment plate 203 is fixedly connected to one side of the pressure spring 202, and an adjustment bolt 204 is fixedly connected to one side of the torque adjustment component 2.

[0019] Specifically, when the operator uses the device, they rotate the adjusting bolt 204 to move the adjusting plate 203, thereby changing the compression degree of the pressure spring 202. The elastic force of the pressure spring 202 acts on the torque adjusting ring 3, thereby changing the friction between the torque adjusting ring 3 and the drive sprocket 1, thus achieving the adjustment of the transmitted torque.

[0020] Furthermore, such as Figure 3 As shown, the following preferred technical solutions are provided: The adjusting bolt 204 has a nut 205 threaded onto its surface, and a bushing 206 is fitted onto the bottom surface of the spline shaft 201. The purpose of this design is to lock the nut 205 after the adjusting bolt 204 is adjusted to the correct position, preventing the adjusting bolt 204 from loosening due to vibration or other reasons during the operation of the assembly, ensuring the pressure of the pressure spring 202 is stable, and thus ensuring the accuracy of torque adjustment. The bushing 206 is made of wear-resistant material, which can reduce the direct friction between the spline shaft 201 and other components during rotation, reduce the wear rate of the spline shaft 201, and improve its service life.

[0021] Furthermore, such as Figure 1 As shown, the following preferred technical solutions are provided: A connecting flange 4 is fixedly connected to one side of the spline shaft 201. A hole is opened on one side of the connecting flange 4. The purpose of this design is to use the connecting flange 4 as an interface for connecting the component to external equipment. The position and size of the hole match the connection hole of the external equipment. The connecting flange 4 is firmly connected to the external equipment by bolts passing through these holes, so that the power of the spline shaft 201 can be stably transmitted to the external equipment.

[0022] Furthermore, such as Figure 1 As shown, the following preferred technical solutions are provided: A grease filling port 5 is fixedly connected to the center of the surface of the connecting flange 4. A sealing cap 6 is threaded to one end of the grease filling port 5. The purpose of this design is that after the component has been running for a period of time, wear will occur between the moving parts. Grease can be added to the inside of the component through the grease filling port 5 to reduce friction and wear between the parts. When no grease is added, the sealing cap 6 seals the grease filling port 5 to prevent grease from leaking from the filling port. At the same time, it prevents external dust and impurities from entering the inside of the component through the filling port and affecting the normal operation of the component.

[0023] Furthermore, such as Figure 1 As shown, the following preferred technical solutions are provided: A chain 7 is rotatably connected to the surface of the drive sprocket 1, and a driven sprocket 8 is engaged with the inner wall of the chain 7. The purpose of this design is that when the drive sprocket 1 rotates under power, it drives the chain 7 to move through meshing with the chain 7. The chain 7 then drives the driven sprocket 8 to rotate through meshing with the driven sprocket 8, thereby transmitting the power of the drive sprocket 1 to the driven sprocket 8, realizing the transmission of power between different components and meeting the working requirements of the equipment.

[0024] Furthermore, such as Figure 4 As shown, the following preferred technical solutions are provided: An end cover 9 is fixedly connected to the back of the drive sprocket 1, and screws 12 are fixedly connected around the end cover 9. The purpose of this design is that the end cover 9 can seal the opening on the back of the drive sprocket 1 to prevent external dust, moisture, impurities, etc. from entering the component and avoid contamination and corrosion of internal components. The screws 12 firmly fix the end cover 9 to the drive sprocket 1, ensuring the connection strength and sealing between the end cover 9 and the drive sprocket 1, and ensuring that the internal components can operate in a relatively clean and stable environment.

[0025] Furthermore, such as Figure 1 As shown, the following preferred technical solutions are provided: A fixing plate 10 is fixedly connected to one side of the drive sprocket 1. A guide groove is provided on the inner side of the torque adjusting ring 3. A positioning pin 11 is slidably connected in the middle of the guide groove. The purpose of this design is to fix the positioning pin 11 with the fixing plate 10, so that the positioning pin 11 can stably cooperate with the guide groove on the torque adjusting ring 3. The positioning pin 11 slides in the guide groove, which guides the axial movement of the torque adjusting ring 3, ensuring that the torque adjusting ring 3 can only move in the set direction. At the same time, the cooperation between the positioning pin 11 and the guide groove can ensure that when the drive sprocket 1 rotates, the torque adjusting ring 3 can rotate synchronously with it, avoiding relative rotation between the two and affecting the transmission of torque.

[0026] Working Principle: When using this adjustable torque sprocket assembly, first connect the assembly to the external power source and load equipment via the connecting flange 4, ensuring a secure connection. When torque adjustment is required, rotate the adjusting bolt 204. The adjusting bolt 204 pushes the adjusting plate 203 to compress or release the pressure spring 202. The change in the elastic force of the pressure spring 202 alters the force acting on the torque adjusting ring 3, thereby changing the friction between the torque adjusting ring 3 and the drive sprocket 1, thus achieving torque adjustment. After adjustment, tighten the adjusting bolt 204 with the nut 205 to prevent loosening. During component operation, the drive sprocket 1 rotates under power drive. Through the cooperation of the positioning pin 11 and the guide groove on the torque adjustment ring 3, it drives the torque adjustment ring 3 to rotate synchronously. The torque adjustment ring 3 then transmits power to the external equipment connected to the connecting flange 4 through components such as the spline shaft 201. At the same time, the drive sprocket 1 drives the driven sprocket 8 to rotate through the chain 7, realizing the coordinated work of multiple components. Regularly add grease to the inside of the component through the grease filling port 5 to reduce friction between parts. After adding grease, tighten the sealing cap 6. The end cap 9, secured by screws 12, protects the internal components from external contamination and ensures long-term stable operation of the component.
