AI Technical Summary
Existing gear reducers have difficulty lubricating two-stage spur gears, and the lubricating oil needs to be added manually, which is inaccurate. Wear particles need to be replaced and filtered regularly. The existing lubrication method is inefficient and inconvenient.
A novel gearbox housing is designed, comprising an oil reservoir, an oil return tank, an oil injector, a hydraulic pump, and a metal shavings absorber. The oil is injected by a piston driven by a screw, achieving precise addition of grease. The oil return system purifies the lubricating oil, allowing it to be recycled and cooled.
It enables precise spraying of grease onto gear meshing points, purifies and recycles lubricating oil, improves lubrication efficiency and oil cleanliness, and simplifies lubrication operations.

[0014] The following will describe in detail the embodiments of this utility model with reference to the accompanying drawings. Detailed Implementation
[0015] The present invention will be further described below with reference to the accompanying drawings and embodiments:
[0016] like Figure 1 As shown, a novel reducer housing includes an upper housing 1, a lower housing 2, two sets of oil reservoirs 3, and a return oil tank 4. The oil reservoirs 3 are installed on the top of the upper housing 1, and the two oil reservoirs 3 are respectively installed above the meshing points of the reducer gears. The bottom of the oil reservoir 3 has an oil outlet hole, and an oil nozzle 5 is installed on the oil outlet hole. A piston 6 is slidably installed in the oil reservoir 3. The top cover of the oil reservoir 3 has an air hole 7. The center of the top cover of the oil reservoir 3 has a threaded hole, and a screw 8 is threadedly connected to the threaded hole. A limit ball 9 is fixedly installed at the bottom of the screw 8, and the limit ball 9 is rotatably installed in the piston 6. The bottom of the lower housing 2 has an oil drain hole 10, and an oil drain pipe 11 is provided between the oil drain hole 10 and the return oil tank 4. A first hydraulic pump 12 is installed on the oil drain pipe 11. By rotating the screw 8, the piston 6 can be moved up and down. The air hole 7 ensures air pressure balance, and the grease in the oil tank 3 can be accurately sprayed onto the gear meshing part through the oil injector 5.
[0017] It also includes: an iron filings absorber 13, which is connected to the oil return tank 4 by an oil return pipe 14. The iron filings absorber 13 is used to absorb impurities in the lubricating oil.
[0018] An input nozzle is provided on the side wall of the oil storage tank 3. An input pipe 15 is provided between the iron filings adsorber 13 and the input nozzles of the two sets of oil storage tanks 3 respectively. A second hydraulic pump 16 is provided on the input pipe 15 respectively.
[0019] A cooler 17 is installed on the oil return tank 4 to cool the extracted lubricating oil.
