Planetary Gearbox lubricating system
This one is for the cooler and lubricating system. One is lubricating inside with the low density oil.The internal circulation is the splash lubrication. The splash lubrication is the automatic lubrication of the lubricating oil from the oil zone to the friction pair and the bearing by the rotation of the gear. The splash lubrication is mainly applied to the case where the circumferential speed of the gear not higher than 12-14 meters per second. The other one is lubricating outside. When the linear speed of the gear is larger than 12-14 meters per second, the internal lubricating will increase the oil temperature, and some larger gearboxes are not ideal when using internal circulation lubrication. In this case, the external circulation is required. The external lubricating circulation is an oil pump. Injecting oil to the gears and bearings, not only for lubrication, but also for cooling. For the unimportant external circulation of the gearbox, only the oil in the gearbox is pumped out through the oil pump and sent to the various switching points, and then the lubricating oil flows in. In the tank, circulating the important reducer in turn, it is necessary to add a petrol station externally. At this time, the lubricating oil is not directly sent to the lubrication point, but enters the oil station, and the oil station processes the lubricating oil (filtering, cooling, etc.) After that, the lubricating oil is sent to each lubrication point, and the cleaned lubricating oil plays an important role in improving the reliability of the gearbox.
