Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figure 1 and Figure 2An embodiment of this utility model provides an automatic lubrication reduction gearbox, including a gearbox body 1. An oil storage box 2 is fixedly connected to the top of the gearbox body 1 for storing lubricating oil to supply it when the lubricating oil in the gearbox is insufficient. An oil pump 3 is fixedly installed at one end of the oil storage box 2 for conveying lubricating oil. A filter assembly is installed at the output end of the oil pump 3. A silicone hose 7 is connected to one end of the filter assembly. The hose is designed to be twisted for disassembly of the filter assembly. An oil delivery pipe 8 is fixedly connected to one end of the silicone hose 7. An oil nozzle 9 is fixedly connected to the bottom end of the oil delivery pipe 8 through the inner wall of the gearbox body 1. Lubricating oil can be injected into the gears in the gearbox along the oil delivery pipe 8 and the oil nozzle 9. A cooling assembly is installed at the bottom front of the gearbox body 1 to cool the lubricating oil and prevent overheating from causing gear damage and system failure.

[0033] Reference Figure 2 and Figure 4 The cooling assembly includes a liquid storage box 13, a thermoelectric cooler 14, a water pump 15, an inlet pipe 16, a serpentine tube 17, and a return pipe 18. The liquid storage box 13 is fixedly connected to the bottom of the front part of the gearbox body 1 and contains coolant. The thermoelectric cooler 14 is fixedly installed at the front of the liquid storage box 13. The cooling end of the thermoelectric cooler 14 is in contact with the liquid storage box 13 and can cool the coolant inside. The water pump 15 is fixedly installed at one end of the liquid storage box 13 for transporting coolant. The output end of the water pump 15 is fixedly connected to the inlet pipe 16. One end of the inlet pipe 16 passes through the inner wall of the gearbox body 1 and is fixedly connected to the serpentine tube 17, which can increase the flow area of ​​the coolant and ensure the heat exchange and cooling effect. One end of the serpentine tube 17 is fixedly connected to the return pipe 18 for the return of coolant.

[0034] Reference Figure 3 The filter assembly includes a connector 4, a connector 5, a slot 20, and a filter screen 6. The connector 4 is fixedly connected to the input end of the oil pump 3. One end of the connector 4 is threadedly connected to the connector 5, and the connector 5 is fixedly connected to the silicone hose 7. The connector 5 can be separated from the connector 4 by rotation to facilitate cleaning of the inside of the filter assembly. The inner wall of the connector 5 is provided with a slot 20, and the filter screen 6 is engaged with the inner wall of the slot 20. The filter screen 6 can block particulate impurities in the flowing lubricating oil to avoid affecting the stable operation of the gears.

[0035] Reference Figure 3 One end of the connector 4 abuts against the filter screen 6. When assembling the filter assembly, the filter screen 6 is inserted into the slot 20 of the connector 5, and then the connector 4 is assembled until its end abuts against the filter screen 6, thereby limiting the filter screen 6 so that it does not shake or shift.

[0036] Reference Figure 1 and Figure 2A level switch 10 is fixedly installed at one end of the bottom of the inner wall of the gearbox body 1. The oil pump 3 is electrically connected to an external power supply through the level switch 10. The level switch 10 is used to monitor the lubricating oil level in the gearbox. When the lubricating oil is consumed and the level is lower than the set value, the oil pump 3 will be automatically started to replenish the lubricating oil.

[0037] Reference Figure 1 The input end of the oil pump 3 is connected to the inside of the oil storage box 2. After the oil pump 3 is started, it can extract the lubricating oil in the oil storage box 2 and transport it. The oil delivery pipe 8 is fixedly connected to the gearbox body 1. The oil delivery pipe 8 is a rigid pipe that will not deform.

[0038] Reference Figure 2 and Figure 4 A temperature control switch 19 is fixedly installed on one side of the bottom of the inner wall of the gearbox body 1. It can monitor the temperature of the lubricating oil inside the gearbox. The water pump 15 and the semiconductor cooler 14 are electrically connected to an external power supply through the temperature control switch 19. When the lubricating oil temperature is higher than the set value, the semiconductor cooler 14 and the water pump 15 will be started to cool the lubricating oil.

[0039] Reference Figure 5 The top of the oil reservoir 2 is fixedly connected to an oil inlet 11 for adding lubricating oil to the oil reservoir 2. The surface of the oil inlet 11 is threaded with a sealing cap 12, which serves to seal and prevent lubricating oil from flowing out and debris from falling in.

[0040] Reference Figure 4 The input end of the water pump 15 is connected to the inside of the liquid storage box 13, which can extract the coolant in the liquid storage box 13 and transport it. One end of the return pipe 18 passes through the outer wall of the gearbox body 1 and is fixedly connected to the liquid storage box 13. The coolant in the serpentine tube 17 will return to the liquid storage box 13 through the return pipe 18, thus circulating to ensure the cooling effect.

[0041] Working principle: A level switch 10 (model BZ2401) is installed inside the reduction gearbox. When the lubricating oil level drops below the set value due to consumption, the oil pump 3 automatically starts, injecting lubricating oil from the oil reservoir 2 through the oil supply pipe 8 and oil nozzle 9 onto the gears inside the gearbox. This replenishes the lubricating oil without manual operation, providing convenience and timely replenishment. Furthermore, during the oil supply process, the filter screen 6 in the filter assembly blocks particulate impurities in the lubricating oil, preventing them from affecting the stable operation of the gears. The unit is equipped with a temperature control switch 19, model KSD301. When it detects that the lubricating oil temperature is higher than the set value, it will control the start of the semiconductor cooler 14 and the water pump 15. The cooling end of the semiconductor cooler 14 is in contact with the liquid storage box 13, which can cool the coolant inside. Then the water pump 15 pumps the coolant through the inlet pipe 16 to the serpentine tube 17, and finally returns it to the liquid storage box 13 through the return pipe 18, thus circulating. When the coolant flows in the serpentine tube 17, it can exchange heat to reduce the temperature of the lubricating oil and prevent overheating from causing gear damage and system failure.
