Description

Technical Field

[0001] This utility model relates to the field of mechanical transmission equipment technology, and in particular to a gearbox with efficient heat dissipation function. Background Technology

[0002] Currently, gearboxes are key components widely used in various mechanical equipment in the field of industrial transmission. When the equipment operates under high load conditions, the temperature of the lubricating oil inside the gearbox will rise significantly. This not only affects the lubrication effect but may also lead to problems such as aging of seals and accelerated wear of components, thereby reducing the service life and operating efficiency of the equipment.

[0003] In related technologies, traditional gearboxes primarily rely on natural heat dissipation or simple air-cooling devices for cooling. However, these methods have low heat dissipation efficiency and cannot meet the cooling requirements under high-load conditions. Therefore, in practical applications, excessively high oil temperatures often lead to lubrication failure. Furthermore, existing gearbox designs typically lack effective forced cooling mechanisms, making the lubricating oil prone to deterioration under prolonged high-temperature environments, further affecting the normal operation of the equipment.

[0004] The shortcomings of existing technologies lie in the fact that the heat dissipation structure of traditional gearboxes is relatively simple, making it difficult to achieve efficient heat dissipation, especially during high-load operation, where oil temperature control becomes a major challenge. Furthermore, although some gearboxes are equipped with auxiliary devices such as cooling fans, their poor design results in unsatisfactory heat dissipation, and maintenance is inconvenient, increasing operating costs.

[0005] To address the aforementioned issues, a gearbox with high-efficiency heat dissipation is designed. By optimizing the structure of the air intake plate, S-shaped air intake groove, heat dissipation fins, and cooling fan, the cooling efficiency of the lubricating oil is significantly improved, effectively solving the problem of excessively high oil temperature under high load operation and enhancing the stability and reliability of the equipment.

Detailed Implementation

[0026] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0027] Please refer to the following: Figures 1 to 4 A gearbox with efficient heat dissipation function includes a gearbox body 1, a gear transmission assembly and a heat dissipation assembly. The gear transmission assembly is installed inside the gearbox body 1 and includes a set of meshing gears 2.

[0028] The gearbox body 1 also includes an upper housing 101 and a lower housing 102;

[0029] The heat dissipation components include:

[0030] At least one set of drainage plates 2011 is fixed to the outer wall of the lower box 102;

[0031] At least one set of oil pumps 1014 is fixed to the outer wall of the upper housing 101;

[0032] At least one set of heat dissipation fins 2013 is connected to the side end of the heat sink 2011 by bolt threads.

[0033] In the specific implementation process, when it is necessary to lubricate and cool the inside of the gearbox, the oil pump 1014 is started to extract the lubricating oil in the upper housing 101.

[0034] Then it is transported to the S-shaped diversion channel 2012 through the first connecting pipe 1015. The S-shaped diversion channel is opened on one side of the diversion plate 2011 and is connected to the first connecting pipe 1015 and the second connecting pipe 2017 respectively.

[0035] Then, the lubricating oil flows into the lower housing 102 through the second connecting pipe 2017 to complete the circulating cooling process;

[0036] At the same time, the cooling fan 2014 located on the side of the heat sink 2013 is started, which accelerates the dissipation of heat from the surface of the heat sink fins through convection and improves the overall heat dissipation efficiency.

[0037] After the lubricating oil completes its circulation, it flows back to the upper housing 101 through the oil outlet 2015, completing one complete cooling cycle.

[0038] By combining forced oil circulation with an air-cooling device, the gearbox's temperature control capability under continuous high-load operation is significantly improved, extending the equipment's service life.

[0039] refer to Figures 1 to 4 As shown, the upper housing 101 includes an oil inlet 1011, a first plug head 1012, and a first connecting pipe 1015. The oil inlet 1011 is located at the upper end of the upper housing 101. The first plug head 1012 is threadedly connected to the oil inlet 1011. The first connecting pipe 1015 is fixedly connected between the oil pump 1014 and the first plug head 1012.

[0040] It should be noted that the device can achieve rapid injection and sealing control of lubricating oil, thereby ensuring the integrity of the lubrication system before equipment operation or during maintenance, thus ensuring the stable operation of gear transmission components; avoiding the risk of lubricating oil leakage when not being filled, improving the overall sealing performance of the equipment; and facilitating operators to add or replace lubricating oil regularly, improving maintenance efficiency and reducing the difficulty of manual operation.

[0041] refer to Figures 1 to 4 As shown, the lower housing 102 includes an oil outlet 2015, a second plug head 2016, and a second connecting pipe 2017. The oil outlet 2015 is located at the side end of the lower housing 102. The second plug head 2016 is bolted to the inside of the oil outlet 2015. The second connecting pipe 2017 is fixedly connected between the diversion plate 2011 and the second plug head 2016.

[0042] It should be noted that the device can efficiently discharge lubricating oil from the lower housing 102 to the heat dissipation system, thereby forming a complete oil circulation path and improving the overall cooling efficiency of the gearbox; it avoids the residual accumulation of lubricating oil in a non-circulating state, reducing the risk of oil oxidation and impurity deposition; and it facilitates the disassembly, maintenance or replacement of the oil outlet 2015 and the second connecting pipe 2017, improving the convenience and operability of later equipment maintenance.

[0043] refer to Figures 1 to 4As shown, the diversion plate 2011 also includes an S-shaped diversion groove 2012, which is opened at the side end of the diversion plate 2011, with one end connected to the first connecting pipe 1015 and the other end connected to the second connecting pipe 2017.

[0044] It should be noted that when the oil pump 1014 starts, the lubricating oil is drawn from the upper housing 101 through the first connecting pipe 1015 and delivered to one end of the S-shaped drainage channel 2012. This causes the lubricating oil to flow along the curved path of the S-shaped drainage channel 2012, and then enters the second connecting pipe 2017 through its other end, finally flowing back into the lower housing 102. This design extends the flow path of the lubricating oil in the drainage plate and increases the heat dissipation time, which can effectively improve the cooling effect of the lubricating oil. This improves the thermal stability and reliability of the entire gearbox under high load operation, avoids the risk of decreased lubrication performance or equipment damage due to excessive oil temperature, facilitates efficient circulation and continuous heat dissipation of the lubricating oil, and meets the needs of long-term continuous operation.

[0045] refer to Figures 1 to 4 As shown, the heat sink 2013 also includes a cooling fan 2014, which is disposed on the side of the heat sink 2013 and is electrically connected to an external power supply.

[0046] It should be noted that when the gearbox is operating under high load, the cooling fan 2014 starts, which accelerates the airflow speed on the surface of the heat sink fins 2013 through forced air cooling, thereby enhancing the heat exchange efficiency between the heat sink fins and the external environment. This can significantly improve the cooling capacity of the lubricating oil circulation system in high-temperature environments, thus maintaining the internal temperature of the gearbox within a reasonable range. This effectively prevents failures such as decreased lubrication performance, seal aging, or component deformation caused by excessively high oil temperature, avoiding unplanned downtime or shortened service life due to overheating. It also facilitates active control of the gearbox operating temperature, improving its stability and safety during continuous operation.

[0047] refer to Figures 1 to 4 As shown, a base 103 is fixedly connected to the lower end of the lower housing 102, and a traction ring 4 is fixedly connected to the upper end of the upper housing 101.

[0048] It should be noted that by setting a base 103 at the bottom of the lower housing 102, a stable supporting foundation is provided for the entire gearbox. Then, the traction ring 4 set at the top of the upper housing 101 facilitates the hoisting, transportation, and on-site installation of the entire equipment. This design not only enhances the stability and load-bearing capacity of the gearbox structure, but also improves the ease of operation during installation and relocation, thereby increasing on-site maintenance efficiency and equipment layout flexibility. It avoids handling difficulties or safety hazards caused by the lack of a dedicated hoisting structure, and facilitates users to quickly position and install the gearbox under different working conditions.

[0049] The working principle of the gearbox with high-efficiency heat dissipation function provided by this utility model is as follows:

[0050] During operation, the gearbox body 1 is first fixedly installed on the equipment foundation via the base 103. Then, the oil pump 1014 is started to draw lubricating oil from the upper housing 101 and deliver it to the first connecting pipe 1015. Finally, the lubricating oil enters the S-shaped drainage channel 2012, where its tortuous path achieves flow delay and initial cooling. Simultaneously, the cooling fan 2014 is started to provide forced air cooling to the heat dissipation fins 2013, thereby further enhancing the cooling efficiency. Then, the lubricating oil flows into the lower housing 102 via the second connecting pipe 2017, completing one cycle of cooling. The design of the oil outlet 2015 and the second sealing head 2016 ensures smooth return of the lubricating oil. The fluid flows to the upper housing 101 and then enters the next cycle, thus achieving continuous circulation and efficient heat dissipation of the lubricating oil inside the lubrication system, avoiding lubrication failure and component wear caused by high temperature. Then, the first plug 1012 at the oil inlet 1011 is checked regularly, and lubricating oil is replenished or replaced by opening it. During maintenance, the bolt connection structure between the heat dissipation fins 2013 and the diversion plate 2011 is disassembled to facilitate cleaning or replacement of components. Then, the start-stop strategy of the cooling fan 2014 is adjusted according to the equipment operating status to make the system have good adaptability and energy saving. Finally, the whole machine is hoisted and transported by the traction ring 4, improving the convenience of on-site installation and relocation.

[0051] When continuous operation is required for a long time, the gear set 2 is kept in a stable lubrication and good heat dissipation environment, so that the operation of each component is more stable and reliable; thereby effectively extending the service life of the gearbox and improving the overall operating efficiency and safety of the transmission system.
