Description
Technical Field
[0001] The utility model belongs to the technical field related to gear boxes, and particularly relates to a gear box device with high-efficiency heat dissipation. Background Art
[0002] Gearboxes play a critical role in transmission in many industrial equipment, but they easily generate significant heat during operation due to friction between internal components. Poor heat dissipation can lead to excessive oil temperatures and increased component wear, impacting the gearbox's service life and overall equipment stability. Traditional heat dissipation methods sometimes struggle to meet efficiency requirements, especially under high loads and prolonged operation. Therefore, developing gearbox devices with efficient heat dissipation is crucial, aiming to quickly and effectively dissipate heat, ensuring reliable and stable operation of the gearbox and improving overall equipment performance.
[0003] The water cooling channel of the existing gearbox device is usually set in the cooling end cover, mainly for cooling the output shaft. The cooling range is relatively limited, and there is no external heat exchange equipment. The water cooling efficiency is not high, which affects the overall heat dissipation performance and reduces the service life of the gearbox. Utility Model Content
[0004] The purpose of the present invention is to provide a gearbox device with high efficiency in heat dissipation, so as to solve the problems raised in the above background technology.
[0005] To achieve the above-mentioned purpose, the present utility model provides the following technical solutions: a gearbox device with high efficiency in heat dissipation, comprising a gearbox main body;
[0006] A driving screw port is provided at the middle position of the rear side of the gear box body, a first screw port is provided at the upper position of the front side of the gear box body, a second screw port is provided below the first screw port, and a control box is provided at the left rear side of the gear box body;
[0007] A circulating water channel is provided in an annular shape at the inner side of the gear box body, an exchange box is provided at the right front side of the gear box body, a water inlet is provided at the front side of the circulating water channel, and a water outlet is provided at the rear side of the circulating water channel;
[0008] A water pump is provided at the right rear side of the gear box body, a water tank is provided at the right side of the water pump, and a heat exchanger is provided at the inner side of the water tank;
[0009] The water pump is powered by connecting to an external power source.
[0010] Preferably, the water inlet of the circulating water circuit and the exchange box are connected with a water inlet connecting pipe, and the water outlet of the circulating water circuit and the exchange box are connected with a water outlet connecting pipe.
[0011] Preferably, the water pump is connected to the gear box body by bolt connection, and a water inlet pipe and a water outlet pipe are respectively provided at the upper and lower ends of the left side of the water pump.
[0012] Preferably, a connecting water pipe is provided at the left side of the water tank, and the water inlet connecting pipe and the water outlet connecting pipe are respectively connected to the water inlet pipe and the water outlet pipe of the water pump and the connecting water pipe of the water tank.
[0013] Preferably, the inner side of the water tank is filled with liquid, the heat exchanger is specifically a plate heat exchanger, and the heat exchanger and the water tank are welded together.
[0014] Preferably, a water supply port is provided at the lower side of the water tank, and the driving screw port of the gear box body is connected to an external driving device.
[0015] Preferably, a transmission gear set and an output shaft are respectively provided in the first screw port and the second screw port of the gear box body, and the inner side of the gear box body is filled with oil.
[0016] Compared with the prior art, the present invention provides a gearbox device with high efficiency heat dissipation, which has the following beneficial effects:
[0017] 1. By creating a circular circulating water channel inside the gearbox body, water can flow around the entire gearbox, absorbing heat from all parts of the gearbox and preventing local overheating. Compared to traditional water-cooled gearboxes that may only dissipate heat from certain key parts, this ring-shaped design can more comprehensively and evenly remove the heat generated by the gearbox during operation. Whether it is heat generated by the gears, bearings, or other internal components, it can be more effectively removed by the circulating water, thereby better maintaining the overall gearbox at a suitable temperature environment, ensuring stable performance of each component and extending its service life.
[0018] 2. The circulating water circuit is integrated inside the gearbox body, eliminating the need for a large number of complex, space-consuming external water-cooling pipes. This makes the layout of the entire gearbox water-cooling system more compact. This is especially true for equipment installation environments with limited space. This compact design saves space, facilitates reasonable layout with other equipment components, and reduces potential risks such as leakage and collision that may occur due to excessive or excessive external water-cooling pipes.
[0019] 3. A dedicated exchange box is installed, combined with a plate heat exchanger inside the water tank, fully utilizing the advantages of the plate heat exchanger. The plate heat exchanger has a large heat exchange area, and the plates are very thin. The thermal boundary layer formed when hot and cold fluids flow between the plates is thin, resulting in high heat conduction efficiency. This allows for rapid and sufficient heat exchange between the high-temperature water flowing from the gearbox's circulating water circuit and the low-temperature water (or other cooling medium) sent from the water tank within the exchange box. This means that the temperature of the circulating water can be lowered in a relatively short period of time, allowing it to more efficiently re-enter the circulating water circuit to absorb heat from the gearbox, improving the efficiency of the entire water-cooling system and ensuring that the gearbox maintains good heat dissipation even when generating large amounts of heat under high-load operation.
[0020] 4. The gearbox water-cooling assembly features a relatively simple structure, lacking complex filtering and impurity removal mechanisms. This makes daily maintenance relatively easy, eliminating the need for extensive manpower and material resources to frequently clean complex water-cooling channels and maintain numerous filtering devices. In the event of a fault, the structure also makes it easier for maintenance personnel to quickly locate and resolve the issue, reducing equipment downtime due to maintenance, indirectly improving equipment efficiency, and lowering long-term maintenance costs.

[0030] See also Figure 1-4 , the utility model provides a technical solution for a gearbox device with high efficiency in heat dissipation: a gearbox device with high efficiency in heat dissipation, comprising a gearbox body 3;
[0031] A driving screw port 11 is provided at the middle position of the rear side of the gear box body 3, a first screw port 5 is provided at the upper position of the front side of the gear box body 3, a second screw port 6 is provided below the first screw port 5, and a control box 4 is provided at the left rear side of the gear box body 3;
[0032] A circulating water channel 13 is provided in a ring shape on the inner side of the gear box body 3. An exchange box 8 is provided on the right front side of the gear box body 3. A water inlet is provided on the front side of the circulating water channel 13, and a water outlet is provided on the rear side of the circulating water channel 13.
[0033] A water pump 7 is provided at the right rear side of the gear box body 3, a water tank 1 is provided at the right side of the water pump 7, and a heat exchanger 2 is provided inside the water tank 1;
[0034] The water pump 7 is powered by connecting an external power source.
[0035] A water replenishing port is arranged at the lower side of the water tank 1, a drive screw port 11 of the gear box body 3 is connected to an external driving device, a transmission gear set and an output shaft are respectively arranged in the first screw port 5 and the second screw port 6 of the gear box body 3, and the inside of the gear box body 3 is filled with oil.
[0036] In this embodiment, the external driving device is connected to the gear box body 3 through the drive screw port 11, and power is input into the gear box body 3. A transmission gear set and an output shaft are respectively arranged in the first screw port 5 and the second screw port 6 of the gear box body 3, and the input power is transmitted by the transmission gear set in the gear box. The transmission gear set adjusts the speed and torque of the input power by the mutual meshing of different gears according to the gear ratio and other factors, and then outputs the adjusted power through the output shaft from the corresponding screw port (the first screw port 5 or the second screw port 6) to drive other subsequent equipment components connected thereto, so as to meet the actual requirements for speed and torque under different working conditions.
[0037] The inside of the gear box body 3 is filled with oil, which plays an important lubricating role. During the operation of the gear box, the oil will be brought up by splashing lubrication as the gears rotate, so that the oil can contact the key parts such as gears and bearings that need to be lubricated, reduce the friction and wear between parts, reduce the heat generated by friction, and help to ensure the normal operation of the parts in the gear box and prolong their service life. At the same time, the oil can also take away part of the heat during flow, which has a certain heat dissipation effect, and helps to maintain the internal temperature of the gear box within a relatively reasonable range, ensuring the stable and reliable operation of the entire transmission system.
[0038] The control box 4 located at the left rear side of the gear box body 3 can control and monitor related parameters during the operation of the entire gear box. For example, it can monitor the temperature, pressure and other operating conditions inside the gear box, collect data through the built-in sensor, and judge the operating state of the gear box according to the pre-set program and parameter range.
[0039] For example, Figure 1-4As shown, the water inlet of the circulating water circuit 13 and the exchange box 8 are connected with a water inlet connecting pipe 9, the water outlet of the circulating water circuit 13 and the exchange box 8 are connected with a water outlet connecting pipe 10, the water pump 7 is connected to the gear box body 3 by a bolt connection method, and the upper and lower ends of the left side of the water pump 7 are respectively provided with a water inlet pipe and a water outlet pipe, a connecting water pipe 12 is provided at the left side of the water tank 1, the water inlet connecting pipe 9 and the water outlet connecting pipe 10 are respectively connected with the water inlet pipe, the water outlet pipe of the water pump 7 and the connecting water pipe 12 of the water tank 1, the inner side of the water tank 1 is filled with liquid, the heat exchanger 2 is specifically a plate heat exchanger 2, and the heat exchanger 2 and the water tank 1 are welded together.
[0040] Preferably, the water pump 7 is started by obtaining electrical energy from an external power source. The upper and lower ends of the left side of the water pump 7 are respectively provided with a water inlet pipe and a water outlet pipe, which are used to extract the liquid in the water tank 1 and transport it to the corresponding pipeline. The water tank 1 is located at the right rear side of the gear box body 3. A water replenishment port is provided on its lower side to replenish the liquid in the water tank to ensure that there is enough water to participate in the circulation. A plate heat exchanger 2 is provided inside the water tank 1, and the two are welded together. The heat exchanger 2 is used to achieve heat exchange.
[0041] Water pumped by the water pump 7 is delivered through the outlet pipe and the water inlet connecting pipe 9 to the water inlet of the circular water circuit 13 formed inside the gearbox body 3. The water then enters the circular water circuit 13. The circular water circuit 13 surrounds the interior of the gearbox body and is in full contact with the gearbox body, effectively absorbing heat dissipated from the gearbox during operation.
[0042] The water flowing through circulating water circuit 13 absorbs heat, raising its temperature. The heat-carrying water then flows out of the outlet of circulating water circuit 13, passing through outlet connecting pipe 10 and entering exchange box 8. Within exchange box 8, the hot water exchanges heat with the relatively low-temperature water delivered from water tank 1 via connecting pipe 12. This process primarily relies on heat exchanger 2 for efficient heat exchange. Heat exchanger 2, with its large heat exchange area and high heat exchange efficiency, rapidly transfers heat from the hot water to the low-temperature water, lowering the temperature of the hot water exiting circulating water circuit 13 to a relatively low temperature.
[0043] After the heat exchange in the exchange box 8, the water, which has been cooled, flows back into the water tank 1 through the corresponding pipes and re-enters the next round of circulation. This cycle continues, continuously removing the heat generated by the gearbox body 3, achieving efficient heat dissipation for the gearbox, ensuring that the gearbox can operate stably within the appropriate temperature range, avoiding failures of components such as gears and bearings due to overheating, extending the service life of the gearbox, and maintaining its good working performance.
[0044] Preferably, the whole water cooling assembly is driven by the water pump 7 to circulate water, absorbs heat by the circulating water path 13, exchanges heat by the exchange box 8 and the heat exchanger 2, and returns to the water tank 1 for recycling, which cooperates to achieve the purpose of high-efficiency heat dissipation and provides strong temperature guarantee for the stable work of the gear box main body 3.
[0045] Although the embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
