Description
Technical Field
[0001] This utility model relates to the field of synchronous pulley and synchronous belt technology, and in particular to a double-layer toothed noise-reducing and anti-slip synchronous belt. Background Technology
[0002] Double-sided toothed synchronous belts are transmission belts with a double-sided tooth structure, mainly used for bidirectional transmission. They are widely used in various mechanical systems, and perform particularly well in applications requiring complex bidirectional transmission. Based on their tooth profile, double-sided toothed belts can be further divided into trapezoidal toothed double-sided toothed synchronous belts and circular arc toothed double-sided toothed synchronous belts.
[0003] However, during the operation of double-sided toothed synchronous belts and pulleys, especially under prolonged working conditions, the friction generated between the synchronous belt and pulleys causes a significant amount of heat to accumulate. This heat can easily lead to deformation and aging of the toothed surfaces of the pulleys and belts under high temperatures, affecting not only the anti-slip effect between the belt and pulleys but also reducing the lifespan of the synchronous belt. Frequent replacement by operators is necessary, impacting overall work efficiency. Utility Model Content
[0004] This utility model discloses a double-layer toothed noise-reducing and anti-slip synchronous belt, which aims to solve the technical problems of synchronous pulleys and synchronous belts.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A double-layer toothed noise-reducing and anti-slip synchronous belt includes a mounting frame. A drive shaft and a driven shaft are rotatably connected to the inner side of the mounting frame. Synchronous pulleys are fixedly provided on the surfaces of both the drive shaft and the driven shaft. A double-layer synchronous belt is installed between the two synchronous pulleys. Several anti-slip tooth blocks are fixedly provided on the upper and lower surfaces of the double-layer synchronous belt.
[0007] The surface of the mounting frame is provided with a heat dissipation mechanism, which is used to ventilate and dissipate heat on the contact surface between the double-layer synchronous belt and the synchronous pulley. The heat dissipation mechanism includes a heat dissipation ventilation box fixedly connected to the front of the mounting frame. A protective shell is fixedly provided on the upper surface of the heat dissipation ventilation box. An air pump is fixedly provided inside the protective shell. Two annular ventilation pipes are fixedly provided on the inner surface of the mounting frame. Several ventilation holes are opened on the surface of the annular ventilation pipes.
[0008] In a preferred embodiment, a semiconductor cooling chip is fixedly embedded on the front side of the heat dissipation and ventilation box, and an air inlet is opened on the lower surface of the heat dissipation and ventilation box. A dust removal mesh plate is fixedly connected to the lower surface of the heat dissipation and ventilation box, and a cooling fan is fixedly installed on the surface of the heat dissipation and ventilation box. The air inlet end of the cooling fan corresponds to the heat dissipation surface of the semiconductor cooling chip.
[0009] In a preferred embodiment, a plurality of flow guide baffles are fixedly connected to the inner wall of the heat dissipation and ventilation box, the flow guide baffles are evenly distributed inside the heat dissipation and ventilation box, and an air intake pipe is fixedly connected to the air pump, the end of the air intake pipe away from the air pump extending into the interior of the heat dissipation and ventilation box.
[0010] In a preferred embodiment, the output end of the air pump is fixedly connected to an air guide pipe, the end of the air guide pipe away from the air pump extends into the interior of the mounting bracket and is fixedly connected to a diversion air pipe, the two ends of the diversion air pipe being fixedly connected to the input ends of two annular ventilation pipes respectively.
[0011] In a preferred embodiment, the positions of the annular ventilation pipes correspond to the two synchronous pulleys, and a plurality of ventilation holes are evenly distributed in a circular array on the surface of the annular ventilation pipes.
[0012] In a preferred embodiment, a plurality of the anti-slip teeth are symmetrically distributed on the upper and lower surfaces of the double-layer synchronous belt. The anti-slip teeth are trapezoidal, and the surface of the anti-slip teeth is provided with a polyurethane aramid fiber composite layer.
[0013] In a preferred embodiment, a drive motor is fixedly mounted on the back of the mounting bracket, and the rotation shaft of the drive motor extends into the interior of the mounting bracket and is fixedly connected to one end of the drive shaft rod.
[0014] As can be seen from the above, the double-layer toothed noise-reducing and anti-slip synchronous belt provided by this utility model has the following technical effects.
[0015] Firstly, by setting a heat dissipation mechanism on the surface of the mounting frame, during the operation of the synchronous belt, the air pump can be used to input cooling air from the heat dissipation and ventilation box into two annular ventilation pipes. Then, several ventilation holes on the surface of the annular ventilation pipes are used to blow air onto the meshing area between the synchronous pulley and the double-layer synchronous belt, thereby achieving heat dissipation and cooling between the synchronous pulley and the double-layer synchronous belt. This prevents the synchronous belt from deforming and aging after high temperature, which is beneficial to improving the service life and anti-slip effect of the double-layer synchronous belt.
[0016] Secondly, by symmetrically setting anti-slip tooth blocks on the upper and lower surfaces of the double-layer synchronous belt, the double-sided symmetrical tooth design can make the load distribution of the synchronous belt balanced, which is conducive to improving the tensile strength of the synchronous belt. Furthermore, by setting a polyurethane aramid fiber composite layer on the surface of the anti-slip tooth blocks, it is beneficial to improve the dynamic friction coefficient of the synchronous belt surface, and it can still maintain a certain transmission efficiency in oily environments.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0025] Reference Figure 1 and Figure 2 A double-layer toothed noise-reducing and anti-slip synchronous belt includes a mounting frame 1. A drive shaft 2 and a driven shaft 3 are rotatably connected to the inner side of the mounting frame 1. A drive motor 8 is fixedly mounted on the back of the mounting frame 1. The rotation shaft of the drive motor 8 extends into the interior of the mounting frame 1 and is fixedly connected to one end of the drive shaft 2.
[0026] Both the drive shaft 2 and the driven shaft 3 are fixedly provided with synchronous pulleys 4, and a double-layer synchronous belt 5 is installed between the two synchronous pulleys 4. Several anti-slip teeth 6 are fixedly provided on the upper and lower surfaces of the double-layer synchronous belt 5.
[0027] It is worth noting that by symmetrically setting anti-slip tooth blocks 6 on the upper and lower surfaces of the double-layer synchronous belt 5, the double-sided symmetrical tooth design can make the load distribution of the synchronous belt balanced, which is beneficial to improving the tensile strength of the synchronous belt.
[0028] It should be noted that several anti-slip tooth blocks 6 are symmetrically distributed on the upper and lower surfaces of the double-layer synchronous belt 5. The anti-slip tooth blocks 6 are trapezoidal, and the surface of the anti-slip tooth blocks 6 is provided with a polyurethane aramid fiber composite layer. The polyurethane aramid fiber composite layer is a high-performance composite material that combines the elasticity and wear resistance of polyurethane with the high strength characteristics of aramid fiber. It also has excellent impact resistance and good energy absorption effect.
[0029] It is worth noting that by setting a polyurethane aramid fiber composite layer on the surface of the anti-slip tooth block 6, it is beneficial to improve the dynamic friction coefficient of the synchronous belt surface, and it can still maintain a certain transmission efficiency in an oily environment.
[0030] Reference Figure 3 and Figure 4 In a preferred embodiment, the surface of the mounting frame 1 is provided with a heat dissipation mechanism 7. The heat dissipation mechanism 7 is used to ventilate and dissipate heat on the contact surface between the double-layer synchronous belt 5 and the synchronous pulley 4. The heat dissipation mechanism 7 includes a heat dissipation ventilation box 701 fixedly connected to the front of the mounting frame 1. A protective shell 702 is fixedly provided on the upper surface of the heat dissipation ventilation box 701. An air pump 703 is fixedly provided inside the protective shell 702. Two annular ventilation pipes 704 are fixedly provided on the inner surface of the mounting frame 1. Several ventilation holes 705 are opened on the surface of the annular ventilation pipes 704.
[0031] The positions of the annular ventilation pipe 704 correspond to the two synchronous pulleys 4 respectively. Several ventilation holes 705 are evenly distributed in a circular array on the surface of the annular ventilation pipe 704. The ventilation holes 705 are used to ventilate and dissipate heat at the meshing point between the synchronous pulley 4 and the double-layer synchronous belt 5.
[0032] Reference Figure 5 It should be noted that a semiconductor cooling chip 706 is fixedly embedded on the front of the heat dissipation and ventilation box 701, and an air inlet is opened on the lower surface of the heat dissipation and ventilation box 701. A dust removal mesh plate 707 is fixedly connected to the lower surface of the heat dissipation and ventilation box 701, and a cooling fan 708 is fixedly installed on the surface of the heat dissipation and ventilation box 701. The air inlet end of the cooling fan 708 corresponds to the heat dissipation surface of the semiconductor cooling chip 706.
[0033] It is worth noting that by providing a heat dissipation mechanism 7 on the surface of the mounting bracket 1, during the operation of the synchronous belt, the air pump 703 can be used to input cooling air from the heat dissipation and ventilation box 701 into the two annular ventilation pipes 704. Then, the ventilation holes 705 on the surface of the annular ventilation pipes 704 can be used to blow air onto the meshing area between the synchronous pulley 4 and the double-layer synchronous belt 5, thereby achieving heat dissipation and cooling between the synchronous pulley 4 and the double-layer synchronous belt 5, which is beneficial to improving the service life and anti-slip effect of the double-layer synchronous belt 5.
[0034] It should be further explained that several flow guide baffles 709 are fixedly connected to the inner wall of the heat dissipation and ventilation box 701. The flow guide baffles 709 are evenly distributed inside the heat dissipation and ventilation box 701. By setting the flow guide baffles 709, the air intake can be blocked and guided, and the air flow speed can be slowed down, so that the air is evenly cooled by the semiconductor cooling chip 706.
[0035] An air intake pipe 710 is fixedly connected to the air inlet end of the air pump 703. The end of the air intake pipe 710 away from the air pump 703 extends into the interior of the heat dissipation and ventilation box 701. An air guide pipe 711 is fixedly connected to the output end of the air pump 703. The end of the air guide pipe 711 away from the air pump 703 extends into the interior of the mounting bracket 1 and is fixedly connected to a split air pipe 712. The two ends of the split air pipe 712 are fixedly connected to the input ends of two annular ventilation pipes 704 respectively. Cooling air can be input into the two annular ventilation pipes 704 using the air guide pipe 711 and the split air pipe 712.
[0036] Working principle: In use, the drive motor 8 drives the drive shaft 2 to rotate, which in turn drives the driven shaft 3 to rotate. At the same time, the double-layer synchronous belt 5 rotates on the surfaces of the drive shaft 2 and the driven shaft 3. Then, the semiconductor cooling chip 706 cools and lowers the air inside the heat dissipation and ventilation box 701. The air pump 703 draws air into the heat dissipation and ventilation box 701, and the air inlet is used to feed air into the heat dissipation and ventilation box 701. Then, the air guide pipe 711 and the split air pipe 712 are used to distribute the cooled air to two annular ventilation pipes 704. Then, the ventilation holes 705 on the surface of the annular ventilation pipes 704 are used to ventilate and cool the meshing point between the synchronous pulley 4 and the double-layer synchronous belt 5, thereby achieving the effect of heat dissipation for the double-layer synchronous belt 5.

The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
