[0002] In the field of geared motor technology, gearboxes, as an important transmission device, are widely used in various industrial equipment and mechanical systems. However, during long-term high-load operation, traditional gearboxes often generate a large amount of heat inside the gearbox, leading to temperature rise. High temperatures not only affect the operating efficiency and service life of the gearbox, but may also cause component wear, aging, or even failure, posing a threat to the stable operation of the equipment.

[0003] To address this issue, existing gearboxes typically employ external cooling fans or water-cooling systems for heat dissipation. However, these methods often suffer from drawbacks such as high energy consumption, complex structures, and large space requirements. Therefore, achieving efficient heat dissipation, reducing energy consumption, and extending equipment lifespan while ensuring stable gearbox performance has become a pressing technical challenge in the field of geared motor technology.

[0015] In summary, this application includes at least one of the following beneficial technical effects:

[0016] 1. High-efficiency heat dissipation performance: Through the heat dissipation mechanism, including components such as oil box, piston cylinder, piston disc, linkage push rod, movable frame, first linkage gear, transmission shaft and second linkage gear, the rotation of the motor shaft drives the circulation of lubricating oil, thereby achieving high-efficiency heat dissipation of the gear box. The lubricating oil circulates between the gear box and oil box through the first circulation guide pipe and the second circulation guide pipe, increasing the heat dissipation area and improving the heat dissipation efficiency. No additional oil circulation power equipment is required, which helps to reduce energy consumption.

[0017] 2. Compact and stable structure: The cooling mechanism of the gearbox is tightly integrated with the gearbox body and gear box, with a compact structure that does not occupy extra space.

[0024] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0025] Reference Figures 1-4 A gearbox with a high-efficiency heat dissipation structure mainly includes a base, a gearbox body 1, a gearbox 2, a heat dissipation mechanism 3, a motor shaft 4, and a protective cover 5. The gearbox body 1 is fixedly mounted on the upper surface of the base, the gearbox 2 is fixedly connected to the right end of the gearbox body 1, the heat dissipation mechanism 3 is cleverly positioned on the surface of the gearbox 2 to achieve efficient heat dissipation, the motor shaft 4 is rotatably mounted on the surface of the gearbox 2 as a power input component, and the protective cover 5 protects the heat dissipation mechanism 3 from external interference.

[0026] The heat dissipation mechanism 3 is the core innovation of this embodiment, and its detailed structure is as follows: An oil reservoir 301 is fixedly connected to the surface of the gearbox 2 for storing and circulating lubricating oil. A semiconductor cooling chip 311 is embedded in the inner wall of the oil reservoir 301, with its cooling surface located inside the oil reservoir 301 to reduce the temperature of the lubricating oil. Furthermore, a cooling fan 312 is fixedly mounted on the surface of the oil reservoir 301, with its air intake end corresponding to the heat dissipation surface of the semiconductor cooling chip 311 to accelerate heat dissipation.

[0027] The oil piston cylinder 302 is fixedly mounted on the surface of the oil tank 301, and a piston disc 303 is slidably mounted inside it. A linkage push rod 304 is fixedly connected to the upper surface of the piston disc 303. The top end of the linkage push rod 304 extends to the outside of the piston cylinder 302 and is rotatably connected to the movable frame 305. This design allows the up-and-down movement of the piston disc 303 to drive the corresponding movements of the linkage push rod 304 and the movable frame 305.

[0028] A first linkage gear 306 is fixedly connected to the surface of the motor shaft 4, while a transmission shaft 307 is rotatably connected to the outer surface of the gearbox 2. A second linkage gear 308 is fixedly connected to the surface of the transmission shaft 307. When the motor shaft 4 rotates, the first linkage gear 306 drives the second linkage gear 308 and the transmission shaft 307 to rotate synchronously. A linkage disc 313 is fixedly connected to the end of the transmission shaft 307, and a movable shaft 314 is fixedly connected to the surface of the linkage disc 313. The end of the movable shaft 314 is rotatably connected to the top surface of the movable frame 305. Therefore, the rotation of the motor shaft 4 can, through this series of linkage structures, ultimately drive the movable frame 305 to reciprocate, thereby driving the piston disc 303 to move up and down inside the piston cylinder 302.

[0029] Two first circulation guide pipes 309 are fixedly connected to the upper surface of the oil tank 301. The ends of the two first circulation guide pipes 309 away from the oil tank 301 extend upwards to the top of the gear box 2. A guide shell 310 is also fixedly connected to the surface of the gear box 2. The guide shell 310 is connected to the gear box 2 via an oil connecting pipe, used to transport the lubricating oil in the guide shell 310 to the interior of the gear box 2. The top ends of both first circulation guide pipes 309 extend into the interior of the guide shell 310 to achieve the circulation of the lubricating oil.

[0030] The bottom end of the piston cylinder 302 is fixedly fitted with an inlet pipe 315 and an outlet pipe 316. The end of the inlet pipe 315 away from the piston cylinder 302 extends into the interior of the oil box 301 and is equipped with a one-way inlet valve to prevent oil backflow. The surface of the outlet pipe 316 is fixedly equipped with a one-way outlet valve to ensure that the oil can only be discharged in one direction. The end of the outlet pipe 316 away from the piston cylinder 302 is fixedly connected to a second circulation guide pipe 317. The end of the second circulation guide pipe 317 away from the outlet pipe 316 extends into the interior of the oil box 301, and its outlet is located directly below the oil box 301. This design allows the piston disc 303 to circulate lubricating oil between the oil box 301 and the gear box 2 through the inlet pipe 315, the outlet pipe 316, and the second circulation guide pipe 317 when the piston disc 303 moves up and down.

[0031] The implementation principle of a gearbox with a high-efficiency heat dissipation structure according to an embodiment of this application is as follows: During use, the motor shaft 4 of the gearbox rotates, driving the first linkage gear 306 to rotate. The first linkage gear 306, through meshing, drives the second linkage gear 308 and the transmission shaft 307 to rotate synchronously. The rotation of the transmission shaft 307, in turn, drives the movable frame 305 to reciprocate through the linkage disc 313 and the movable shaft 314. The oscillation of the movable frame 305 then drives the linkage push rod 304 and the piston disc 303 to move up and down within the piston cylinder 302.

[0032] When the piston disc 303 moves upward, it draws lubricating oil into the oil box 301 through the inlet pipe 315; when the piston disc 303 moves downward, it discharges the lubricating oil back to the bottom of the oil box 301 through the drain pipe 316 and the second circulation guide pipe 317. This cycle not only achieves the circulation of lubricating oil, but also increases the heat dissipation area and improves heat dissipation efficiency.

[0033] Meanwhile, the thermoelectric cooler 311 inside the oil box 301 continuously reduces the temperature of the lubricating oil, while the cooling fan 312 accelerates the dissipation of heat generated by the thermoelectric cooler 311. The design of the flow guide shell 310 and the oil connecting pipe ensures that the lubricating oil can circulate between the gear box 2 and the flow guide shell 310, further guaranteeing the lubrication and heat dissipation effects of the gear box 2.

[0034] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
