Description

Technical Field

[0001] This utility model relates to the field of gearbox technology, and in particular to a shock-resistant heavy-duty reducer gearbox structure. Background Technology

[0002] In industrial production, gearboxes, as critical power transmission devices, are widely used in various heavy machinery and equipment. However, under heavy loads and complex operating conditions, gearboxes and their connecting shafts often bear enormous dynamic loads and vibrations. This not only affects the transmission accuracy and stability of the equipment but may also accelerate the wear of components and even lead to equipment failure. Traditional gearbox structures often prioritize strength and rigidity in their design, while providing relatively insufficient protection against vibration and shock. This is especially true for the connecting shaft, which directly participates in power transmission and is subject to more significant vibration and shock. Therefore, effectively reducing the vibration of the connecting shaft under heavy loads and complex operating conditions, and improving the overall seismic resistance of the gearbox, has become an urgent problem to be solved in current industrial production.

The air column 10 is in contact with the inner wall; a sealing ring is provided at the contact point between the mounting pipe 8 and the through groove 6. The air column 10 is a cylindrical polyethylene pipe filled with nitrogen. The air column 10 inside the sleeve 4 acts as an elastic element, which can effectively absorb and disperse the vibration energy generated by the connecting shaft 3 under heavy load and complex working conditions. The elastic deformation of the air column 10 can buffer axial and radial impacts, reduce the vibration amplitude of the connecting shaft 3, and thus improve the overall vibration resistance of the gearbox. The air column 10 inside the sleeve 4 can be adjusted for inflation and deflation according to actual working conditions and needs to adapt to different vibration reduction requirements. The air column 10 and the through groove are... The components are staggered; when the connecting shaft 3 rotates and vibrates, the vibration energy is transferred to the mounting tube 8. The rubber connecting strip 9 and the air column 10 on the surface of the mounting tube 8 work together to absorb and disperse this vibration energy. The air column 10 is filled with gas. When subjected to vibration pressure, the air column 10 is compressed, the gas volume decreases, and the pressure increases. According to the gas law, gas absorbs energy during compression. When the vibration pressure decreases or disappears, the air column 10 expands back to its original shape, releasing the absorbed energy, thus playing a role in buffering and shock absorption. The rubber connecting strip 9 has good elasticity and, under vibration... Elastic deformation occurs, further absorbing and dispersing vibration energy; the rubber material has a large internal resistance, which can convert some vibration energy into heat energy and dissipate it, reducing the transmission of vibration; the air column 10 and the rubber connecting belt 9 work together to form a flexible buffer system; the air column 10 mainly bears and buffers larger vibration impacts, while the rubber connecting belt 9 plays a better role in absorbing and attenuating smaller vibrations and high-frequency vibrations; the two work together to effectively reduce the impact of the vibration generated by the rotation of the connecting shaft 3 on the gearbox body 2 and other components, and improve the vibration resistance and operational stability of the entire reducer gearbox.

[0027] Furthermore, the surface of the air column 10 is provided with a rubber protective pad to prevent the air column 10 from being damaged by friction with the inner wall of the sleeve 4, which could lead to air leakage and affect subsequent use.

[0028] Furthermore, the bottom end of the mounting plate 7 is provided with an annular connecting plate 11, and the top end of the sleeve 4 is provided with an annular connecting groove 12 that contacts the connecting plate 11. This facilitates the connection between the connecting plate 11 and the connecting groove 12, allowing the mounting plate 7 and its bottom components to be installed inside the sleeve 4.

[0029] Furthermore, the inner bottom end of the sleeve 4 is provided with a first groove 13 at equal intervals in an annular shape, and the surface of the mounting plate 7 is provided with a second groove 14 at equal intervals in an annular shape. A cover plate 15 is provided on one side of the mounting plate 7. A first screw 16 is connected to the inside of the first groove 13 and the second groove 14 at equal intervals in an annular shape on one side of the cover plate 15. A second screw 17 is connected to one end of the first screw 16. Nuts are respectively connected to the surfaces of the first screw 16 and the second screw 17. This is to facilitate the first screw 16 to pass through the two grooves and to install the two nuts on the two screws respectively, so that the surface of the mounting plate 7 can be fixed inside the sleeve 4.

[0030] Furthermore, a pressure sensor is installed inside the sleeve 4. The pressure sensor is connected to an alarm and control system, which allows the pressure sensor to detect and alert immediately if the air column 10 is damaged and leaks.

[0031] Furthermore, the threads on the surfaces of the first screw 16 and the second screw 17 are arranged in opposite directions to prevent the nut from loosening due to vibration, thus achieving an anti-loosening effect.

[0032] Furthermore, a sealing ring is provided at the connection between the connecting plate 11 and the connecting groove 12, which facilitates sealing of the contact area between the connecting plate 11 and the connecting groove 12 to prevent nitrogen leakage.
