What should be paid attention to when lubricating planetary gear reducers

The lubrication of planetary reducers is also a crucial stage for their maintenance. The transmission system of open and semi closed gear reducers, or closed test transmission gears with lower speed, are usually lubricated with regular oil during work, and the commonly used lubricant is lubricating oil or lubricating oil. The lubrication of planetary reducers also has its own standards, and the lubrication standards for different planetary reducers are also different.

When the circumferential speed of the gear of the planetary reducer is greater than 12m/S, gasoline pump lubrication should be used, that is, the oil provided by the gasoline pump or the oil station provided by the core at a certain load should be sprayed into the surface of the meshing table of the gear teeth through the nozzle. When v ≤ 25m/s, the nozzle can be at the edge of gear tooth engagement or whistle out; When v>25m/s, the nozzle should be on the whistling side of the gear teeth to facilitate early cooling of the newly engaged gear teeth with lubricating oil, while also lubricating the gear teeth.

The lubrication method of a universal closed test gear reducer transmission system is determined by the circumferential speed of the gear. When the circumferential speed V of the gear is less than 12m/s, the teeth of the large gear are often immersed in oil for lubrication. That way, when the gears are in the transmission system, they bring lubricating oil into the surface of the teeth, and at the same time, they also throw the oil onto the surface of the box to remove heat. The deep visibility of gear penetration into oil depends on the magnitude of the circumferential velocity of the gear. For cylindrical gears, it is usually not more than one tooth high, but it should not be less than 10mm; For bevel gears, the full tooth width should be penetrated, and at least half of the tooth width should be penetrated. In multi-level transmission gears, oil can be carried into the tooth surface of gears that have not penetrated into the oil by using an oil wheel.
