[0002] A gearbox is a power transmission mechanism that uses gears to reduce the rotational speed of a motor to a desired speed while providing a larger torque. Gearboxes are widely used in power and motion transmission systems, found in almost every type of machinery, from ships, automobiles, and locomotives in transportation, to heavy construction machinery, processing tools and automated production equipment in the machinery industry, and even everyday appliances and clocks. Their applications range from high-power transmission to low-load, precise angle transmission. Currently, gearboxes are secured by end covers, but these end covers, being solid metal structures, rely solely on surface heat dissipation. This fails to quickly dissipate the heat generated by the gear meshing inside the gearbox, leading to high-temperature lubrication failure and shortened component lifespan. Therefore, improvements are needed. Utility Model Content

[0024] Reference Figures 1 to 5 The present invention provides a further description of an embodiment of a gearbox end cover.

[0025] A gearbox end cover includes an end cover body 1 and multiple fixing holes 2. It also includes a heat dissipation mechanism disposed within the end cover body 1 to accelerate heat dissipation. The heat dissipation mechanism includes a contact element 3 disposed within the heat dissipation mechanism for contacting a heat-generating element; a heat-conducting element 4 disposed within the contact element 3 and fixedly connected to it; a heat dissipation element 5 disposed on the heat-conducting element 4 and fixedly connected to it; an isolation ring 6 disposed within the end cover body 1 and fixedly connected to it; a heat dissipation groove 7 disposed on the end cover body 1 for heat dissipation; a filter screen 8 disposed on the heat dissipation groove 7 for filtration; and two filtration mechanisms disposed within the contact elements 3 for filtration.

[0026] With this configuration, the contact element 3 is in close contact with the lubricating oil during operation, and the side of the contact element 3 that contacts the lubricating oil is a spiral guide boss. Utilizing the rotational power of the gearbox during operation, the lubricating oil is driven to flow along the lead direction of the spiral boss, forming an "oil spiral circulation". At the same time, the spiral groove increases the contact area between the oil and the end cover, accelerating the transfer of heat from the oil to the contact element 3, and then the heat is quickly conducted to the heat conduction element 4 through the contact element 3. The heat conduction element 4 further transfers the heat to the heat dissipation element 5. The heat dissipation element 5 dissipates the heat quickly to the surrounding environment through its large surface area. Meanwhile, the isolation ring 6 effectively isolates different areas inside the end cover body 1, preventing heat from accumulating inside. The setting of the heat dissipation groove 7 increases the air circulation channel, further improving the heat dissipation efficiency, while the filter screen 8 can block external dust and impurities from entering the end cover.

[0027] refer to Figure 1 and Figure 2 In a preferred embodiment, the heat dissipation mechanism includes: a mounting part disposed inside the end cover body 1 for mounting components; and a lifting part disposed on the mounting part for lifting the contact member 3.

[0028] refer to Figure 3 In a preferred embodiment, the mounting part includes: a mounting bracket 9, which is disposed inside the end cover body 1 and fixedly connected to the end cover body 1; and a threaded rod 10, which is disposed inside the end cover body 1 and rotatably connected to the end cover body 1.

[0029] refer to Figure 2 and Figure 3 In a preferred embodiment, the lifting unit includes: a rotating wheel 11, which is disposed on the threaded rod 10 and fixedly connected to the threaded rod 10; and a lifting member 12, which is disposed on the threaded rod 10 and threadedly connected to the threaded rod 10.

[0030] With this setup, during operation, the gearbox end cover is securely installed on the gearbox through the fixing hole 2. Then, the rotating wheel 11 is manually rotated, which drives the threaded rod 10 to rotate. When the threaded rod 10 rotates, it drives the lifting component 12 to move, moving the contact component 3 and bringing it into contact with the lubricating oil. When the gearbox starts working, the gears inside the gearbox mesh and generate heat. At this time, the heat dissipation mechanism begins to function. The contact component 3 is in close contact with the lubricating oil, and the contact component 3 is fixedly connected to the lifting component 12.

[0031] refer to Figure 2 In a preferred embodiment, the filtration mechanism includes: a liquid inlet section disposed within the contact member 3 for liquid inlet operation; and a filtration section disposed within the liquid inlet section for filtration operation.

[0032] refer to Figure 5 In a preferred embodiment, the liquid inlet section includes: a liquid inlet tank 13, which is disposed within the contact member 3 and fixedly connected to the contact member 3; and a liquid inlet valve 14, which is disposed within the liquid inlet tank 13 and fixedly connected to the liquid inlet tank 13.

[0033] refer to Figure 5 In a preferred embodiment, the filtration unit includes: a filter box 15, which is disposed in the liquid inlet box 13 and fixedly connected to the liquid inlet box 13; and an outlet valve 16, which is disposed in the liquid inlet box 13 and fixedly connected to the liquid inlet box 13.

[0034] With this configuration, during operation, the inlet valve 14 in the inlet tank 13 controls the entry of coolant. After the coolant enters the filter box 15, it is filtered by the filter section to remove impurities and particles, ensuring the purity of the coolant. The pure coolant then flows out through the outlet valve 16 to cool key parts such as the contact parts 3, carrying away heat and forming a good heat dissipation cycle. The filter box 15 is provided with filter holes, and the filter holes on the side closer to the inlet valve 14 have a larger diameter.

[0035] This device, by incorporating a heat dissipation mechanism, effectively solves the problem of existing gearbox end covers failing to quickly dissipate heat generated by gear meshing within the gearbox. Contact element 3 maintains close contact with the lubricating oil, and the spiral guide protrusion facilitates a "spiral circulation" of the lubricating oil, increasing the contact area between the oil and the end cover and accelerating heat transfer. Furthermore, the device features a filtration mechanism. The inlet valve 14 of the inlet tank 13 controls the entry of coolant, the filter tank 15 filters the coolant, and the outlet valve 16 allows the purified coolant to flow out and cool critical components, forming a beneficial heat dissipation cycle. This significantly improves the heat dissipation performance of the gearbox end cover and extends the service life of components.

[0036] Working Principle: When using this device, firstly, the gearbox end cover is securely installed on the gearbox through the fixing hole 2. Then, the rotating wheel 11 is manually rotated. The rotating wheel 11 drives the threaded rod 10 to rotate, which in turn moves the lifting component 12, causing the contact component 3 to move and come into contact with the lubricating oil. When the gearbox starts working, the gears inside generate heat through meshing. At this time, the heat dissipation mechanism begins to function. The contact component 3 is in close contact with the lubricating oil, and the side of the contact component 3 that contacts the lubricating oil is a spiral guide boss. Utilizing the rotational power of the gearbox during operation, the lubricating oil is driven to flow along the lead direction of the spiral boss, forming an "oil spiral circulation." Simultaneously, the spiral groove increases the contact area between the oil and the end cover, accelerating the transfer of heat from the oil to the contact component 3. The heat is then rapidly conducted to the heat-conducting component 4 through the contact component 3. The heat is further transferred to the heat sink 5, which quickly dissipates the heat to the surrounding environment through its large surface area. At the same time, the isolation ring 6 effectively isolates different areas inside the end cover 1, preventing heat from accumulating inside. The heat sink 7 increases the airflow channel, further improving the heat dissipation efficiency. The filter screen 8 can block external dust and impurities from entering the end cover, protecting the internal parts from damage. During the heat dissipation process, the filtration mechanism also works simultaneously. The inlet valve 14 in the inlet tank 13 controls the entry of coolant. After the coolant enters the filter box 15, it is filtered by the filter section to remove impurities and particles, ensuring the purity of the coolant. The pure coolant then flows out through the outlet valve 16 to cool key parts such as the contact parts 3, carrying away heat and forming a virtuous heat dissipation cycle.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
