Description

Technical Field

[0001] This utility model belongs to the field of automotive transmission system technology, specifically an aluminum alloy tube high-speed transmission shaft assembly. Background Technology

[0002] In the non-ferrous metallurgical industry, the LF furnace is the most commonly used refining method. However, during prolonged smelting, severe electro-corrosion and arcing occur between the contact surfaces of the conductive chuck and the conductive crossarm. This damages both the conductive chuck and the conductive crossarm, with severe electro-corrosion melting and burning of the 6mm thick copper layer on the end face of the conductive crossarm. This prevents current from being properly transmitted from the end face of the conductive crossarm to the conductive chuck, causing the current to be directly melted through the bolts. Furthermore, the electro-corrosion and arcing cause the internal sealing ring to burn out, leading to water leakage. This could potentially cause a production interruption in the refining furnace. Additionally, water entering the steel poses a significant safety risk. The lack of a copper layer on the end face of the conductive crossarm results in insufficient conductivity and makes copper welding impossible. Replacing the entire conductive arm is not economical. If not addressed promptly, this will directly cause the steelmaking refining furnace to shut down.

[0003] Meanwhile, a high-speed aluminum alloy drive shaft (announcement number CN219954009U) is disclosed, suitable for high-speed and high-stability mechanical transmission. This device includes a shaft body with sliding forks at both ends. The shaft body is an aluminum alloy tube, which is hollow. A first sliding fork and a second sliding fork are connected to both ends of the tube via universal joints. The outer end face of the first sliding fork has a first spline hole, and the outer end face of the second sliding fork has a second spline hole. Two shaft fork arms are provided at 180-degree intervals at the end of the tube. Two sliding fork arms are also provided at 180-degree intervals at the inner ends of the first and second sliding forks. Four connecting arms are provided at 90-degree intervals at the universal joints. The two shaft fork arms and the two sliding fork arms are connected to the four connecting arms respectively.

[0004] One of the core advantages of this patented high-speed aluminum alloy drive shaft during use is its adaptability to mechanical scenarios where the transmission distance may vary in high-speed transmission. A fixed length would be unsuitable for equipment with different shaft lengths, assembly errors in transmission systems, or scenarios where distance deviations occur due to vibration or thermal expansion and contraction during operation. For example, in some special machinery with variable shaft lengths or precision equipment requiring high assembly accuracy, a fixed-length drive shaft would be difficult to apply due to its inability to adapt, thus losing the versatility of the original patent.

[0005] Therefore, an aluminum alloy tube high-speed transmission shaft assembly is proposed to address the above problems. Utility Model Content

[0006] To address the problems mentioned in the background art, this utility model provides an aluminum alloy tube high-speed transmission shaft assembly, which can be matched with equipment of different shaft spacing and different transmission component layouts by adjusting the length, greatly improving the versatility of the assembly and reducing the cost of equipment production and spare parts inventory.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a high-speed transmission shaft assembly for aluminum alloy tubes, comprising a fixed disk, a second central shaft fixedly mounted on the upper end face of the fixed disk, a first bevel gear fixedly mounted on the outside of the second central shaft, a mounting cylinder fixedly mounted on the upper end face of the first bevel gear, a second bevel gear fitted to the outside of the first bevel gear, and a first rotating shaft fixedly mounted inside the second bevel gear. Through the first and second bevel gears, the transmission direction can be changed to adapt to different working scenarios. Compared to other transmission methods, bevel gear transmission has the characteristics of high transmission efficiency and strong load-bearing capacity, and can stably transmit power under high-speed operation.

[0008] Preferably, a rotating handle is fixedly provided on the left end face of the rotating shaft one, and a central shaft one is fixedly provided on the right end face of the bevel gear two, with the central shaft one and the central shaft two being arranged through each other.

[0009] By adopting the above technical solution, the rotating handle can directly drive the rotating shaft one and the bevel gear two to rotate, thereby realizing the control of the entire transmission system. The operation is simple and intuitive.

[0010] Preferably, a second fixing rod is fixedly provided on the right end face of the rotating handle, and a protective shell is fixedly provided on the right end face of the second fixing rod, and the protective shell is fixedly set with the fixing plate.

[0011] By adopting the above technical solution, the second fixing rod not only connects the handle and the protective shell, but also enhances the stability of the entire structure.

[0012] Preferably, a telescopic rod is fixedly provided on the upper end face of the protective shell, and a spring is fixedly provided on the outside of the telescopic rod, and the spring is fixedly set with the protective shell.

[0013] By adopting the above technical solution, the spring has the function of buffering and shock absorption. When the drive shaft assembly is subjected to impact or vibration during operation, the spring can absorb and disperse energy, reduce damage to the assembly, and improve the reliability and stability of the assembly.

[0014] Preferably, a connecting plate is fixedly provided on the upper end face of the telescopic rod, and a fixing rod is fixedly provided inside the connecting plate.

[0015] By adopting the above technical solution, the connecting plate enables the component to be flexibly connected with other parts, while the fixing rod further enhances the stability of the connection.

[0016] Preferably, a lead screw is fixedly provided on the upper part of the second central shaft, a nut is spirally provided on the outside of the lead screw, and a limiting plate is fixedly provided on the upper end face of the lead screw.

[0017] By adopting the above technical solution, the component can achieve high adjustment accuracy through the lead screw and nut.

[0018] Preferably, a telescopic cylinder is fixedly provided on the upper end face of the nut, and a rotating shaft is fixedly provided on the upper end face of the telescopic cylinder.

[0019] By adopting the above technical solution, the position of the second rotating shaft can be changed through the telescopic cylinder, thereby meeting the transmission requirements between different devices and improving the adaptability and versatility of the components.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model, through the adjustable length design of bevel gear one and bevel gear two, allows the transmission shaft assembly to flexibly adapt to different installation requirements. For example, when adapting to different models of special machinery or industrial equipment, there is no need to customize a transmission shaft of a specific length for each type of equipment. The same component can be matched with equipment with different shaft spacing and different transmission component layouts by adjusting the length, which greatly improves the versatility of the component and reduces the cost of equipment production and spare parts inventory.

[0021] 2. This utility model uses a lead screw and nut to precisely convert rotary motion into linear motion. When the component is in high-speed transmission, the relative position of the lead screw and nut can be adjusted to drive the telescopic cylinder and the rotating shaft to achieve a small distance adjustment, easily meeting the high precision requirements of precision equipment for transmission position and avoiding equipment malfunctions caused by transmission deviation. For example, in the power transmission of precision machine tools, it can ensure the dimensional accuracy of processed parts. Attached Figure Description

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.

[0028] The following describes an embodiment of this utility model based on its overall structure.

[0029] like Figures 1 to 4 As shown, this utility model provides a high-speed transmission shaft assembly made of aluminum alloy tube, including a fixed disk 8. A central shaft 14 is fixedly mounted on the upper end surface of the fixed disk 8. A bevel gear 10 is fixedly mounted on the outside of the central shaft 14. An mounting cylinder 9 is fixedly mounted on the upper end surface of the bevel gear 10. A bevel gear 12 is fitted to the outside of the bevel gear 10. A rotating shaft 11 is fixedly mounted inside the bevel gear 12. Through the bevel gear 10 and the bevel gear 12, the length adjustable design allows the transmission shaft assembly to flexibly adapt to different installation requirements. For example, when adapting to different models of special machinery or industrial equipment, it is not necessary to customize a transmission shaft of a specific length for each type of equipment. The same assembly can be matched with equipment with different shaft spacing and different transmission component layouts by adjusting the length, which greatly improves the versatility of the assembly and reduces the cost of equipment production and spare parts inventory.

[0030] In this embodiment, a handle 5 is fixedly provided on the left end face of the rotating shaft 11, and a central shaft 13 is fixedly provided on the right end face of the bevel gear 12. The central shaft 13 and the central shaft 14 are connected through each other. By rotating the handle 5, the rotating shaft 11 and the bevel gear 12 can be directly driven to rotate, thereby realizing the control of the entire transmission system. The operation is simple and intuitive.

[0031] A fixing rod 6 is fixedly provided on the right end face of the rotating handle 5, and a protective shell 7 is fixedly provided on the right end face of the fixing rod 6. The protective shell 7 is fixedly set with the fixing plate 8. The fixing rod 6 not only connects the rotating handle 5 and the protective shell 7, but also enhances the stability of the entire structure.

[0032] A telescopic rod 3 is fixedly provided on the upper end face of the protective shell 7. A spring 4 is fixedly provided on the outside of the telescopic rod 3, and the spring 4 is fixedly set with the protective shell 7. The spring 4 has the function of buffering and shock absorption. When the drive shaft assembly is subjected to impact or vibration during operation, the spring 4 can absorb and disperse energy, reduce damage to the assembly, and improve the reliability and stability of the assembly.

[0033] A connecting plate 1 is fixedly provided on the upper end face of the telescopic rod 3. A fixing rod 2 is fixedly provided inside the connecting plate 1. The connecting plate 1 enables the component to be flexibly connected with other parts, while the fixing rod 2 further enhances the stability of the connection.

[0034] A lead screw 17 is fixedly mounted on the upper part of the central shaft 14. A nut 16 is screwed on the outside of the lead screw 17. A limiting plate 18 is fixedly mounted on the upper end face of the lead screw 17. Through the lead screw 17 and the nut 16, the assembly has a high adjustment accuracy.

[0035] A telescopic cylinder 19 is fixedly provided on the upper end face of the nut 16, and a rotating shaft 15 is fixedly provided on the upper end face of the telescopic cylinder 19. The position of the rotating shaft 15 can be changed through the telescopic cylinder 19, thereby meeting the transmission requirements between different equipment and improving the adaptability and versatility of the components.

[0036] Working principle and process of a high-speed transmission shaft assembly made of aluminum alloy tube: When the handle 5 is rotated, it drives the fixed rod 6, which is fixedly connected to it, to rotate. Since a protective shell 7 is fixedly mounted on the right end face of the fixed rod 6, and the protective shell 7 is fixedly mounted to the fixed disk 8, the rotation of the handle 5 will not directly affect the position of the protective shell 7 and the fixed disk 8. Simultaneously, the rotation of the handle 5 drives the rotating shaft 11, which is fixed on its left end face, to rotate. The rotation of the rotating shaft 11 drives the bevel gear 12, which is fixed inside it, to rotate. Since the bevel gear 12 is externally fitted to the bevel gear 10, the rotation of the bevel gear 12 drives the bevel gear 10 to rotate through meshing. The bevel gear 10 is fixed to the outside of the central shaft 14, so the central shaft 14 rotates together with the bevel gear 10. The rotation of the central shaft 14 drives the lead screw 17, which is fixed on it, to rotate. A nut 16 is screwed onto the outside of the lead screw 17. According to the lead screw and nut transmission principle, the rotation of the lead screw 17 will cause the nut 16 to move linearly along the lead screw 17. A telescopic cylinder 19 is fixedly mounted on the upper end face of the nut 16, so the telescopic cylinder 19 will move linearly along with the nut 16. A rotating shaft 15 is fixedly mounted on the upper end face of the telescopic cylinder 19, so the rotating shaft 15 will also move linearly. During the rotation of the handle 5, the telescopic rod 3 and the spring 4 fixed on the upper end face of the protective shell 7 play a role in buffering and stabilizing. When the handle 5 rotates, a certain amount of vibration and impact may be generated. The spring 4 can absorb this energy and reduce the impact of vibration on the entire assembly. The telescopic rod 3 can ensure the relative position stability between the protective shell 7 and the connecting plate 1. A fixing rod 2 is fixedly installed inside the connecting plate 1. The connecting plate 1 is connected to the protective shell 7 through the telescopic rod 3. This allows the entire assembly to be connected to other components, realizing the transmission of power and the linkage of equipment. A limiting plate 18 is fixedly installed on the upper end face of the lead screw 17. When the nut 16 moves upward along the lead screw 17 to a certain position, it will contact the limiting plate 18, thereby limiting the continued upward movement of the nut 16 and preventing the nut 16 from coming off the lead screw 17, thus ensuring the safety and stability of the entire assembly.
