How to lubricate the gear reducer?

How to lubricate the gear reducer.The lubrication of the reducer is also a very important link to maintain the reducer.Open and semi-overhead reducer drives or low-speed closed gear drives are usually lubricated periodically by humans, using oil or grease as the lubricant.The lubrication of the reducing agent also has its own conditions, and the lubrication conditions of different reducers are also different.Let's take a look at how Shanghai Jinchuan reducer lubricates the gear reducer.
When the peripheral speed of the gear of the reducer is greater than 12m/s, oil injection lubrication should be used, that is, the oil should be provided by the oil pump or the central power supply station~fixed pressure, and the lubricating oil should be sprayed onto the meshing table of the gear teeth through the nozzle.When V≤25M/s, the nozzle can be located at the meshing edge of the gear teeth or at the edge of the whistle; when v>25m/s, the nozzle should be located at the side of the gear teeth, so that the newly meshed gear teeth can be lubricated with lubricating oil in time , while lubricating the gear teeth.
Generally, the lubrication method of the closed gear reducer transmission is determined according to the peripheral speed of the gear.When the peripheral speed V of the gear is less than 12m/s, the teeth of the large gear are usually immersed in the oil ground for leaching lubrication.In this way, when the gears are driven, the lubricating oil is brought to the meshing tooth surfaces, and the oil is also thrown against the box wall to dissipate heat.The depth to which a gear is immersed in oil depends on the peripheral speed of the gear.For cylindrical gears, it usually does not exceed one tooth height, but usually should not be less than 10mm; bevel gears should be immersed in the full tooth width, at least half the tooth width.In multi-stage gear transmission, the oil can take the tooth surface of the oil to the gear that is not immersed in the oil ground through the belt oiler
The amount of oil in the sump depends on the power of the gear drive.For single-stage transmission, the speed of each IKW electric power is 0.35~0.7Lo.For multi-stage transmissions, the oil requirement is multiplied by the stages.
