Description

Technical Field

[0001] This utility model belongs to the field of gearbox heat dissipation technology, specifically, it relates to an auxiliary heat dissipation structure for gearboxes. Background Technology

[0002] As a core component of mechanical transmission systems, gearboxes are widely used in high-power-density applications such as wind power, ship propulsion, and heavy engineering machinery.

[0003] The heat generated by the meshing of internal gears and friction with bearings can easily lead to an increase in oil temperature. If the heat dissipation is insufficient, it will cause problems such as a decrease in lubricating oil viscosity, oxidation and deterioration, and thermal expansion and deformation of components, ultimately threatening the reliability of the equipment. Therefore, we need a gearbox auxiliary heat dissipation structure.

[0004] However, traditional heat dissipation solutions mostly rely on fixed-spacing heat dissipation fins to conduct heat away from the gearbox housing through natural convection or forced air cooling. However, with fixed and densely arranged heat dissipation fins, dust tends to accumulate in the narrow gaps after long-term operation, forming a heat insulation layer. Conventional cleaning tools are unable to thoroughly remove the dust in the dead corners, resulting in a significant decrease in heat dissipation efficiency over time. The dust layer hinders the transfer of heat from the fin surface to the air, forcing the gearbox to be in an overheated state for a long time. At the same time, maintenance personnel need to frequently disassemble the heat dissipation module for deep cleaning, which will cause equipment downtime, and violent cleaning can easily cause fin deformation.

[0005] To address the aforementioned issues, this application proposes an auxiliary heat dissipation structure for gearboxes. Utility Model Content

[0006] In view of the problems in the related technologies, this utility model proposes a gearbox auxiliary heat dissipation structure to overcome the above-mentioned technical problems existing in the existing related technologies.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A gearbox auxiliary heat dissipation structure includes a gearbox base, an oil supply pipe fixedly connected to the outer wall of the gearbox base, an oil pump fixedly connected to the end of the oil supply pipe away from the gearbox base, an oil storage tank fixedly connected to the output end of the oil pump, a mounting base inserted into the top of the oil storage tank, a heat-conducting rod fixedly connected to the bottom of the mounting base, a sliding groove formed on the top of the mounting base, heat dissipation fins slidably connected to the mounting base through the sliding groove, an adjusting rod fixedly connected to the bottom outer wall of the heat dissipation fins, a collar fixedly connected to the end of the adjusting rod away from the heat dissipation fins, a guide rod fixedly connected to the outer wall of the mounting base, and the heat dissipation fins slidably connected to the guide rod through the collar.

[0009] Preferably, the end of the oil reservoir away from the oil pump is fixedly connected to an oil outlet pipe, and the end of the oil outlet pipe away from the oil reservoir is fixedly connected to a filter box. The side of the filter box away from the oil outlet pipe is fixedly connected to the outer side wall of the gearbox base. A sealing plate is snapped onto the outer side wall of the filter box. By setting up the filter box and the sealing plate, it is convenient to filter the lubricating oil inside the oil reservoir and prevent the residue generated by the operation of the gears in the gearbox base from re-entering the interior of the gearbox base.

[0010] Preferably, a mounting bracket is fixedly connected to the side of the sealing plate near the filter box. The mounting bracket is used to reinforce the filter material. By setting the mounting bracket, it is easy to fix the filter material inside the filter box and prevent the filter material inside the filter box from collapsing during use.

[0011] Preferably, a pressure rod is rotatably connected to the side of the mounting base away from the guide rod. The pressure rod is arc-shaped, and its outer side wall abuts against the top of the oil tank. By setting the pressure rod, it is convenient for operators to disassemble the heat dissipation structure.

[0012] Preferably, a turbine fan is rotatably connected to the bottom of the oil tank. The turbine fan is located on both sides of the oil inlet of the oil tank. By setting the turbine fan, the lubricating oil inside the oil tank can generate eddies, thereby improving the heat dissipation efficiency.

[0013] Preferably, a gearbox cover is detachably connected to the top of the gearbox base, a sealing ring is fixedly connected to the outer side wall of the gearbox base, a transmission rod is rotatably connected to the inner side wall of the sealing ring, and a bearing is fixedly connected to the outer side wall of the transmission rod. By setting the bearing, the friction between the sealing ring and the gearbox base can be reduced, thereby reducing operating losses.

[0014] In summary, the technical effects and advantages of this utility model are as follows: This gearbox auxiliary heat dissipation structure, through the coordinated use of an oil reservoir, mounting base, heat-conducting rod, sliding groove, heat dissipation fins, adjusting rod, collar, and guide rod, facilitates the operator to adjust the spacing between multiple heat dissipation fins, directly exposing the gaps between the heat dissipation fins. This allows the operator to thoroughly clean dust from hard-to-reach areas using tools such as brushes and air guns, avoiding incomplete cleaning due to limited space. Furthermore, the spacing between the heat dissipation fins can be adjusted to match the heat dissipation requirements.

[0015] The use of the oil reservoir, mounting base, and pressure rod facilitates the disassembly of the heat dissipation structure, preventing oil stains and dust from sticking to the oil reservoir after prolonged use, thereby improving the maintenance efficiency of operators.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figure 1-3A gearbox auxiliary heat dissipation structure includes a gearbox base 1, an oil supply pipe 2 fixedly connected to the outer wall of the gearbox base 1, an oil pump 3 fixedly connected to the end of the oil supply pipe 2 away from the gearbox base 1, the oil pump 3 being connected to an external power supply, an oil storage tank 4 fixedly connected to the output end of the oil pump 3, a mounting base 6 inserted into the top of the oil storage tank 4, and heat-conducting rods 7 fixedly connected to the bottom of the mounting base 6. Multiple heat-conducting rods 7 are arranged linearly along the bottom of the mounting base 6 and are all located inside the oil storage tank 4. When lubricating oil flows through the inside of the oil storage tank 4, the multiple heat-conducting rods 7 contact the lubricating oil respectively. A sliding groove 8 is provided on the top of the mounting base 6. The mounting base 6 is slidably connected to heat dissipation fins 9 via a sliding groove 8. Multiple heat dissipation fins 9 are provided and are linearly distributed along the sliding groove 8. Taking one heat dissipation fin 9 as an example, an adjusting rod 10 is fixedly connected to the bottom outer wall of the heat dissipation fin 9. The outer wall of the mounting base 6 is provided with a slot, and the adjusting rod 10 is located inside the slot. The end of the adjusting rod 10 away from the heat dissipation fin 9 extends to the outside of the mounting base 6. A collar 11 is fixedly connected to the end of the adjusting rod 10 away from the heat dissipation fin 9. A guide rod 12 is fixedly connected to the outer wall of the mounting base 6. The collar 11 is sleeved on the outside of the guide rod 12. The heat dissipation fin 9 is slidably connected to the guide rod 12 through the collar 11.

[0025] During use, operators can adjust the spacing between multiple heat dissipation fins 9 using the adjusting rod 10 and collar 11 to match different heat dissipation needs. After prolonged use, a large amount of dust accumulates on the outer wall of the heat dissipation fins 9. At this time, operators can adjust the spacing between multiple heat dissipation fins 9 using the adjusting rod 10 and collar 11 and along the guide rod 12. This makes it easier for operators to thoroughly clean the dust in the dead corners using tools such as brushes and air guns, avoiding incomplete cleaning due to the narrow space between multiple heat dissipation fins 9. This prevents dust accumulation from hindering the transfer of heat from the heat dissipation fin surface to the air, and also prevents dust accumulation from reducing the effective ventilation area, thereby reducing heat dissipation efficiency.

[0026] Reference Figure 2 and Figure 4An oil outlet pipe 5 is fixedly connected to the end of the oil tank 4 away from the oil pump 3. A filter box 14 is fixedly connected to the end of the oil outlet pipe 5 away from the oil tank 4. The side of the filter box 14 away from the oil outlet pipe 5 is fixedly connected to the outer wall of the gearbox base 1. A sealing plate 15 is snapped onto the outer wall of the filter box 14. The interior of the filter box 14 can be filled with filter material, which can be stainless steel mesh. This material is based on high mechanical strength and can maintain structural stability under high pressure and high flow rate conditions, avoiding the decrease in filtration accuracy or filter screen breakage caused by stress deformation. At the same time, its high temperature resistance allows it to effectively intercept impurities in high temperature oil environment, while resisting the deformation risk caused by thermal expansion, ensuring long-term operational reliability. Moreover, the stainless steel mesh can be reused almost without damage through physical cleaning. This recyclable characteristic not only reduces the maintenance cost of frequent filter material replacement, but also meets the needs of sustainable manufacturing.

[0027] Reference Figure 4 A mounting bracket 16 is fixedly connected to the side of the sealing plate 15 near the filter box 14. The outer wall of the mounting bracket 16 fits against the inner wall of the filter box 14, and the corner of the outer wall of the mounting bracket 16 matches the corner of the inner wall of the filter box 14. The mounting bracket 16 is used to reinforce the filter material and prevent the filter material from deforming and collapsing under the high pressure of lubricating oil, thereby extending the service life of the filter material.

[0028] Reference Figure 2 and Figure 3 A pressure rod 13 is rotatably connected to the side of the mounting base 6 away from the guide rod 12. The pressure rod 13 is arc-shaped, and its outer wall abuts against the top of the oil tank 4. Because the pressure rod 13 is arc-shaped, there is an inflection point on its outer wall, and the inflection point is close to the mounting base 6. The inflection point abuts against the top of the oil tank 4, and the pressure rod 13 is rotatably connected to the outer wall of the mounting base 6. When disassembling the mounting base 6 and other heat dissipation parts, the operator can press one end of the pressure rod 13 towards the oil tank 4. Under the action of the inflection point and the oil tank 4, the end of the pressure rod 13 near the mounting base 6 moves away from the oil tank 4, so that the oil tank 4 and the pressure rod 13 form a lever to save the operator's strength.

[0029] Reference Figure 2A turbine fan 17 is rotatably connected to the bottom of the oil reservoir 4. Multiple turbine fans 17 are provided, and the multiple turbine fans 17 are divided into two rows inside the oil reservoir 4. The two rows of turbine fans 17 are symmetrically distributed with the oil inlet of the oil reservoir 4 as the axis of symmetry. The turbine fans 17 are located on both sides of the oil inlet of the oil reservoir 4. When the lubricating oil enters the interior of the oil reservoir 4 along the oil inlet, since the multiple turbine fans 17 are located on both sides of the oil inlet, the lubricating oil will flush the turbine fans 17 on both sides of the oil inlet when it enters the interior of the oil reservoir 4. At this time, under the flushing action of the lubricating oil, the multiple turbine fans 17 rotate. When rotating, they agitate the lubricating oil inside the oil reservoir 4, thereby breaking the low flow rate limitation of natural convection of the oil, increasing the flow rate of the oil, and significantly enhancing the heat exchange efficiency between the fluid and the inner wall of the oil reservoir 4 and the heat-conducting rod 7.

[0030] Reference Figure 1 and Figure 5 A gearbox cover 18 is detachably connected to the top of the gearbox base 1. A sealing ring 19 is fixedly connected to the outer side wall of the gearbox base 1. A transmission rod 20 is rotatably connected to the inner side wall of the sealing ring 19. A bearing 21 is fixedly connected to the outer side wall of the transmission rod 20.

[0031] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
