The gear reducer is widely used in East my country for the slewing mechanism of tower crane machinery. It is widely used in metallurgy, mining, lifting, transportation, cement, construction, chemical industry, textile, printing and dyeing, pharmaceutical and other fields.

[0003] The existing method of lubricating planetary gears is to stop the planetary gears, then disassemble the gears one by one and lubricate them with dripping oil, and finally reassemble them. This method is time-consuming and labor-intensive, affecting the use of the planetary gears. Therefore, it is very necessary to propose a planetary gear for a reducer that is easy to lubricate with dripping oil.

[0004] The existing patent (publication number: CN219082181U) discloses a planetary gear of a reducer that is convenient for drip oil lubrication, including an annular gear ring and a planetary carrier, one side of the annular gear ring is fixedly connected to a disc, one side of the disc is movably connected to an input shaft, one side of the input shaft is provided with a notch, a rotating rod is movably connected in the notch, the circumferential outer wall of the rotating rod is fixedly connected to a rotating block, one side of the rotating block is provided with a top block, and the top block is located in the notch, the circumferential outer wall of the rotating rod is movably connected to a torsion spring, and the two ends of the torsion spring are respectively fixed to the rotating rod and the input shaft. This utility model can not only lubricate the planetary gear in its working state through the cooperation of the rubber oil bag and the top block, thereby reducing the time for lubrication after disassembly, but also can conveniently control the speed of the output shaft on the planetary carrier through the cooperation of the sun gear and the pinion, thereby improving the practicality of the planetary gear, and can also control the flow rate of the rubber oil bag by rotating the top block to shrink or extend the screw.

[0005] In response to the above problems, the existing patent provides a solution. When lubricating the gears inside the existing gear reducer, since most gear reducer cavities are fixed and sealed with multiple bolts in conjunction with a snap-fit ​​structure, it is very troublesome to add oil and lubricate them. In order to add more or less each time, most people pour the lubricating oil into a measuring cylinder and then manually pour it into the gear reducer cavity, which is quite troublesome.
