How to lubricate the gear reducer. About the lubrication of the gearbox, for the maintenance of the gearbox is also a very important link. Open and semi-open gear reducers, or lower-speed closed gear drives, are usually lubricated with periodic refueling by human work, using lubricants or greases. The lubrication of the gearbox also has its own conditions, for different gearbox lubrication conditions are also different. Here’s a look at how to lubricate the gear reducer.
When the gear of the gear of the reducer has a circular speed of >12m/S, oil injection lubrication should be used, i.e. oil supply by the oil pump or the central supply station to a fixed pressure supply, by the nozzle to spray lubricant to the rodent surface of the teeth. When v≤25m/s, the nozzle is located on the rodent or whistle edge of the teeth, and when v>25m/s, the nozzle should be on the side of the tooth whistle in order to cool the newly engaged teeth in a timely manner with lubricant and to lubricate the teeth.
A common closed gear reducer drive, the lubrication method depends on the circumferonal speed of the gear. When the circular speed of the gear V<12m/s, the teeth of the large gear are often immersed in the oil for oil lubrication. In this way, when the gear is moved, the lubricant is brought to the meshed flank and the oil is thrown to the wall of the tank to dissipate heat. The depth of the gear immersed in oil depends on the circumferental speed of the gear, which usually does not exceed one tooth height, but generally should not be less than 10mm; In multistage gear drive, oil can be brought to the flank of the gear that is not immersed in the oil by an oil tanker.
The amount of oil in the tank depends on the amount of power transmitted by the gear. For single-stage drives, the amount of oil required for each transmission of Ikw is approximately 0.35 to 0.7Lo for multi-stage drives, and the amount of oil required is increased by multiples in stages.
