Description

Technical Field

[0001] This utility model relates to the field of gearbox technology, and specifically to a gearbox with rapid heat dissipation. Background Technology

[0002] A gearbox is a mechanical transmission device that converts the high-speed rotation of an electric motor into a low-speed, high-torque output. A gearbox typically consists of an input shaft, an output shaft, a gear set, bearings, and seals. When the motor drives the input shaft to rotate, the gears on the input shaft mesh with each other, driving the gear set on the output shaft to rotate, thus achieving the rotation of the output shaft.

[0003] A large amount of lubricating oil is added inside the gearbox housing to reduce the frictional resistance between the gear contact surfaces. The gearbox generates heat during operation, and this heat increases over time. Because the gearbox housing is enclosed, its heat dissipation performance is poor, making it difficult to cool the lubricating oil inside. Over time, this can lead to gear damage and shorten the gearbox's lifespan. Utility Model Content

[0004] The purpose of this invention is to provide a gearbox with rapid heat dissipation to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a gearbox with rapid heat dissipation, comprising a chassis and a base plate fixedly disposed below the chassis, characterized in that: a heat dissipation assembly is provided on the chassis, and an oil filling assembly is provided on the rear side of the chassis, the heat dissipation assembly comprising an oil pump fixedly disposed on the rear side of the chassis, pipes A, B and C located below the oil pump, a connector A, several fans fixedly disposed above the base plate and located on the right side of the chassis, and a control assembly, one end of pipe A communicating with the interior of the chassis, the other end of pipe A communicating with the oil inlet of the oil pump, both ends of pipe B communicating with the oil outlet of the oil pump and connector A respectively, one end of pipe C communicating with connector A, the other end of pipe C located above the oil pump and communicating with the chassis, pipe C being meandering and located between the chassis and the fans, and both the oil pump and the fans being connected to the control assembly.

[0006] Preferably, the control components include a temperature sensor fixedly mounted on the chassis and a controller fixedly mounted on the base plate, wherein the oil pump, fan and temperature sensor are all connected to the controller via wires.

[0007] Preferably, the refueling assembly includes an oil tank fixedly mounted above the base plate and located at the rear of the chassis, a tee connector, pipes D, E, and F located below the oil pump, valves A, B, and C. One end of pipe D is connected to the left end of the tee connector, and the other end of pipe D is connected to the inside of the chassis. One end of pipe A is connected to the right end of the tee connector and is connected to the inside of the chassis through pipe D. One end of pipe E is connected to connector A, and the other end of pipe E is located above the oil pump and connected to the chassis. Both ends of pipe F are connected to the rear end of the tee connector and the inside of the oil tank, respectively. Valves A and B are installed on pipes C and E, respectively, and valve C is installed on pipe F.

[0008] Preferably, the refueling assembly further includes an oil filter, valve D, and valve E, with valve D and valve E respectively installed on pipe A and pipe D, and the oil filter installed on pipe A and located between valve D and the tee joint.

[0009] Preferably, the connector A is a four-way connector, one end of the pipe C is connected to the right end of the connector A, one end of the pipe E is connected to the left end of the connector A, one end of the pipe B is connected to the lower end of the connector A, and a plug is fixedly provided at the upper end of the connector A.

[0010] Preferably, a refueling pipe is fixedly installed above the fuel tank, and a cap is detachably installed above the refueling pipe.

[0011] Preferably, the tube C is a copper tube.

[0012] The beneficial effects of this utility model are as follows: When using this utility model, lubricating oil is poured into the chassis and oil tank. The oil pump, fan, and temperature sensor are all connected to the controller via wires. All pipes and valves are installed, and the plug is fixed to connector A. Valves A, D, and E are opened, and valves B and C are closed. When the gearbox operates for a long time and the internal temperature of the chassis rises, the temperature sensor will detect this and transmit a signal to the controller. The controller then controls the oil pump and fan to start. The lubricating oil inside the chassis is drawn into the oil pump inlet through pipes D and A, and then sent from the oil pump outlet to pipe B and then to pipe C. Because pipe C is meandering and located between the chassis and the fan, the lubricating oil remains in pipe C for a longer period, thus improving lubrication. The oil transfers heat to pipe C, and the fan blows air onto pipe C to dissipate heat, thus rapidly cooling the lubricating oil. The cooled lubricating oil then re-enters the chassis, quickly lowering the internal temperature of the lubricating oil. Simultaneously, the lubricating oil continuously circulates within the chassis, providing a cooling effect. Once the gearbox stops working and the internal temperature of the chassis has decreased, the controller shuts off the oil pump and fan. In summary, this invention effectively reduces the temperature of the lubricating oil inside the chassis, solving the problem of poor heat dissipation in a closed gearbox chassis, which hinders the cooling of the internal lubricating oil and, over time, damages the gears, thus affecting the gearbox's lifespan.

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0019] like Figure 1-4As shown, this utility model discloses a gearbox with rapid heat dissipation, including a chassis 1 and a base plate 2 fixedly installed below the chassis 1. The chassis 1 is provided with a heat dissipation assembly, and the rear side of the chassis 1 is provided with an oil filling assembly. The heat dissipation assembly includes an oil pump 3 fixedly installed on the rear side of the chassis 1, pipes A4, B5, and C6 located below the oil pump 3, a connector A7, several fans 8 fixedly installed above the base plate 2 and located on the right side of the chassis 1, and a control assembly. One end of pipe A4 is connected to the inside of the chassis 1, and the other end of pipe A4 is connected to the oil inlet of the oil pump 3. Both ends of pipe B5 are connected to the oil outlet of the oil pump 3 and the connector A7, respectively. One end of pipe C6 is connected to the connector A7, and the other end of pipe C6 is located above the oil pump 3 and connected to the chassis 1. Pipe C6 is meandering and located between the chassis 1 and the fans 8. The oil pump 3 and the fans 8 are both connected to the control assembly. In use, lubricating oil is poured into the housing 1 and oil tank 11. The oil pump 3, fan 8, and temperature sensor 9 are connected to the controller 10 via wires. All pipes and valves are installed, and the plug 24 is fixed to the connector A7. Valves A16, D20, and E21 are opened, while valves B17 and C18 are closed. When the gearbox operates for an extended period and the internal temperature of housing 1 rises, the temperature sensor 9 detects this and transmits a signal to the controller 10. The controller 10 then activates the oil pump 3 and fan 8. Lubricating oil inside housing 1 is drawn into the oil pump 3 through pipes D13 and A4, then flows from the oil pump 3 outlet into pipe B5 and finally into pipe C6. Because pipe C6 is meandering and located between housing 1 and fan 8, the lubricating oil remains within pipe C6. Over a prolonged period, the lubricating oil transfers heat to pipe C6, and fan 8 blows air onto pipe C6 to dissipate heat, thus rapidly cooling the lubricating oil. The cooled lubricating oil then re-enters the chassis 1, effectively reducing the temperature of the lubricating oil inside the chassis 1. Simultaneously, the lubricating oil inside the chassis 1 continuously circulates, providing a cooling effect. After the gearbox stops working and the internal temperature of chassis 1 drops, controller 10 shuts down oil pump 3 and fan 8. In summary, this invention effectively reduces the temperature of the lubricating oil inside chassis 1, solving the problem that the gearbox chassis 1 is enclosed, has poor heat dissipation performance, and is inconvenient for cooling the lubricating oil inside the chassis 1, which, over time, leads to gear damage and affects the service life of the gearbox.

[0020] Preferably, the control components include a temperature sensor 9 fixedly mounted on the chassis 1 and a controller 10 fixedly mounted on the base plate 2. The oil pump 3, fan 8, and temperature sensor 9 are all connected to the controller 10 via wires. Since the oil pump 3, fan 8, and temperature sensor 9 are all connected to the controller 10 via wires, it facilitates the control of the opening and closing of each component. (The functions to be implemented by each piece of hardware in this invention are supported by a large number of mature technologies. The essence of this invention lies in the fact that, for specific application scenarios, the above connection and control methods are all existing technologies and do not involve modifications to the internal software of the hardware.)

[0021] Preferably, the refueling assembly includes an oil tank 11 fixedly mounted above the base plate 2 and located behind the chassis 1, a three-way connector 12, pipes D13, E14, and F15 located below the oil pump 3, valves A16, B17, and C18. One end of pipe D13 is connected to the left end of the three-way connector 12, and the other end of pipe D13 is connected to the inside of the chassis 1. One end of pipe A4 is connected to the right end of the three-way connector 12 and is connected to the inside of the chassis 1 through pipe D13. One end of pipe E14 is connected to connector A7, and the other end of pipe E14 is located above the oil pump 3 and is connected to the chassis 1. Both ends of pipe F15 are connected to the rear end of the three-way connector 12 and the inside of the oil tank 11, respectively. Valves A16 and B17 are installed on pipes C6 and E14, respectively, and valve C18 is installed on pipe F15. When the lubricating oil inside chassis 1 needs to be replaced (the lubricating oil inside the gearbox needs to be replaced regularly to help extend the service life of the gearbox), remove plug 24 from the upper end of connector A7, connect the drain pipe to the upper end of connector A7, close valves A16, B17, and C18, open valves D20 and E21, start oil pump 3, so that the lubricating oil inside chassis 1 is drawn into the oil pump 3 inlet end through pipes D13 and A4, and then sent from the oil pump 3 outlet end into pipe B5 and discharged through the drain pipe. After draining the lubricating oil, turn off oil pump 3, re-fix plug 24 to the upper end of connector A7, close valves A16 and E21, open valves B17, C18 and D20, start oil pump 3, so that the lubricating oil inside oil tank 11 is drawn into the oil inlet of oil pump 3 through pipe F15 and pipe A4, and then sent from the oil outlet of oil pump 3 into pipe B5 and then into pipe E14, and then into the machine casing 1 through pipe E14, so that the lubricating oil inside oil tank 11 enters the machine casing 1, completing the lubrication replacement and facilitating the replacement of lubricating oil.

[0022] Preferably, the refueling assembly further includes an oil filter 19, valve D20, and valve E21. Valve D20 and valve E21 are respectively installed on pipe A4 and pipe D13. The oil filter 19 is installed on pipe A4 and located between valve D20 and tee connector 12. Since the oil filter 19 is installed on pipe A4 and located between valve D20 and tee connector 12, it serves to filter the lubricating oil. When the oil filter 19 needs to be replaced, valves D20 and E21 can be closed to replace the oil filter 19, which facilitates the replacement of the oil filter 19.

[0023] Preferably, connector A7 is a four-way connector, with one end of pipe C6 connected to the right end of connector A7, one end of pipe E14 connected to the left end of connector A7, and one end of pipe B5 connected to the lower end of connector A7. A plug 24 is fixedly installed at the upper end of connector A7. Because the plug 24 is fixedly installed at the upper end of connector A7, it prevents lubricating oil leakage when oil is not being discharged.

[0024] Preferably, a refueling pipe 22 is fixedly installed above the fuel tank 11, and a cap 23 is detachably installed above the refueling pipe 22. The fixed refueling pipe 22 facilitates refueling; the detachable cap 23 prevents impurities from entering the fuel tank 11.

[0025] Preferably, the tube C6 is a copper tube. Because the tube C6 is a copper tube, it plays a role in rapid heat dissipation.

[0026] 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.
