Gearboxes are now widely used in many industries and are also frequently used. In order to increase the service life of gearboxes, we must carry out daily maintenance. The lubrication of the gearbox is a very important part of its maintenance. Let's take a look at how the gearbox lubricates the gear reducer:

When the circumferential speed of the gear of the reducer is greater than 12m/S, oil injection lubrication should be used, that is, the oil pump or central oil supply station should supply oil at a certain pressure, and the lubricating oil should be sprayed onto the meshing surface of the gear teeth through a nozzle. When v ≤ 25m/s, the nozzle can be located at either the meshing edge or the whistling edge of the gear teeth; When v>25m/s, the nozzle should be located on the side where the gear teeth whistle out, in order to cool the newly engaged gear teeth in a timely manner with lubricating oil, and also lubricate the gear teeth.
The lubrication method of a universal closed gear reducer transmission 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. In this way, during transmission, the gears bring lubricating oil to the meshing tooth surface and also throw the oil onto the box wall to dissipate heat. The depth of gear immersion in oil can be determined by the circumferential speed of the gear. For cylindrical gears, it is usually not more than one tooth height, but generally should not be less than 10mm; Bevel gears should be immersed in the full tooth width, at least half of the tooth width. In multi-stage gear transmission, oil can be carried onto the tooth surface of gears that have not been immersed in oil by using an oil wheel
The amount of oil in the oil pool depends on the power transmitted by the gears. For a single-stage transmission, for each Ikw of power transmitted, the oil demand is approximately 0.35-0.7Lo. For a multi-stage transmission, the oil demand increases exponentially in stages.
