[0034] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0035] like Figure 1-2As shown, the present application relates to a gearbox cooling device and a reducer using the same. The gearbox cooling device includes a housing 10; the housing 10 is the outer shell of the gearbox, which can protect the components and accommodate multiple components for assembly, thereby achieving multiple functions.

[0036] Preferably, the outer surface of the box body 10 is provided with heat dissipation fins or ribs, which can expand the heat dissipation area and assist heat dissipation through natural convection or forced convection.

[0037] The water inlet pipe 20 is arranged on one side of the box body 10 along the first direction; it can achieve a good water inlet effect, thereby ensuring a good subsequent cooling effect, and at the same time, it can also achieve a good assembly effect.

[0038] The return water pipe 30 is arranged opposite to the water inlet pipe 20 and is located on the other side of the box body 10; it can achieve a good water return effect. At the same time, the return water pipe 30 is arranged opposite to the water inlet pipe 20, which can increase the spacing effect, thereby ensuring sufficient cooling stroke.

[0039] A plurality of cooling pipes 40 are arranged perpendicular to the first direction and between the water inlet pipe 20 and the water return pipe 30 , and can achieve a good cooling effect, thereby directly cooling the components in the box body 10 .

[0040] Preferably, the plurality of cooling pipes 40 adopt a surrounding pipe structure, which enables the cooling branches to be evenly distributed inside the gearbox, especially in the area close to the heat source (gear pair and bearing), ensuring that the cooling water fully covers the high-heat components.

[0041] More preferably, the cooling pipes 40 are arranged in a multi-layer pipe arrangement; 40 multi-layer cooling pipes are arranged in the gearbox wall to form a multiple cooling effect and extend the heat exchange path.

[0042] Furthermore, the inner walls of the plurality of cooling pipes 40 are coated with an anti-corrosion coating (such as a PTFE coating) or a wear-resistant coating, which can extend the life of the pipes and prevent blockage or corrosion caused by long-term use.

[0043] A plurality of connectors 50 are provided at both ends of the cooling pipe 40 and are respectively connected to the water inlet pipe 20 and the water return pipe 30 ; they can achieve a good connection effect between the components, thereby achieving an effect of easy disassembly and assembly.

[0044] The water inlet pipe 20, the cooling pipes 40, and the return pipe 30 are connected in a predetermined order via the connectors 50. The cooling pipes 40 are passed through the housing 10 so that the cooling pipes 40 circulate and cool the components within the housing 10. By interconnecting various pipes to form a water-cooling device and placing the cooling source directly within the housing 10, a good cooling effect can be achieved, thereby increasing the service life of the internal components of the gearbox and ensuring that the gearbox is in good operating condition.

[0045] The purpose of this application is to provide a new gearbox cooling device to help reduce maintenance costs, increase equipment safety and stability, and improve component life.

[0046] From the above description, it can be seen that this application achieves the following technical effects:

[0047] In the embodiment of the present application, a cooling device is added, and the water inlet pipe 20, the cooling pipes 40 and the return pipe 30 are connected in a preset order through the connecting parts 50, and the cooling pipes 40 are passed through the box body 10 so that the cooling pipes 40 circulate and cool the internal components of the box body 10, thereby achieving the purpose of directly circulating and cooling the internal parts of the gearbox, thereby achieving the technical effect of reducing the temperature in the box body 10 and increasing the service life of the parts, thereby solving the current technical problem that a large number of large reducers and transmission mechanisms such as the box body 10 are required in the rolling process of steel products, and during operation, the temperature inside the box body 10 will rise to a higher level due to the influence of the ambient temperature in the workshop and the heat generated by the friction of the parts during the transmission process, thereby reducing the service life of the bearings and increasing the maintenance time of the equipment.

[0048] Furthermore, the water inlet pipe 20 is a main water inlet pipe 20, and a first valve 201 for controlling the cooling water flow rate and on / off state is provided at the end of the main water inlet pipe 20 near the water inlet. It can be understood that the provision of the first valve 201 can achieve a good water inlet on / off effect, thereby ensuring a good control effect.

[0049] Furthermore, the water inlet pipe 20 is provided with a plurality of first light holes 202 connected to the connecting member 50 on one side close to the box body 10. It can be understood that by providing the first light holes 202, a good assembly effect with other components can be achieved.

[0050] Furthermore, the return pipe 30 is a main return pipe 30. A second valve 301 is installed at the end of the main return pipe 30, near the outlet, to control the cooling water flow rate and on / off status. As can be appreciated, the installation of the second valve 301 enables effective return water on / off control, thereby ensuring effective control. The return water passes through the second valve 301 and returns to the central pipeline in the workshop, ensuring effective circulation.

[0051] Furthermore, the first valve 201 and the second valve 301 are ball valves or stop valves. It can be understood that the effect of being easy to achieve and convenient to operate can be achieved.

[0052] Furthermore, the return pipe 30 is provided with a plurality of second light holes 302 connected to the connector 50 on one side close to the box body 10. It can be understood that by providing the second light holes 302, a good assembly effect with other components can be achieved.

[0053] Furthermore, the connecting piece 50 is a pipe joint, and the two ends of the pipe joint are respectively provided with connecting pieces 50 connected to the first light hole 202 and the second light hole 302. It can be understood that good connectivity between the pipes can be ensured.

[0054] Furthermore, the pipe joint is a welded flexible joint. It is understandable that it is convenient to separate the main pipe and the cooling branch pipe.

[0055] Furthermore, the cooling pipes 40 are cooling branches, each made of copper, and the water inlet pipe 20 and the water return pipe 30 are seamless stainless steel pipes. This ensures good heat conduction, thereby achieving a good cooling effect, while also ensuring good structural strength.

[0056] The present application also relates to a speed reducer, comprising the gearbox cooling device as described above.

[0057] The preferred embodiments of the present invention are described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to the specific details in the above embodiments.
