How to lubricate the gear rack reducer? The lubrication of the gearbox is also a very important part of its maintenance. Open and semi open gear reducers, or closed gear transmissions with lower speeds, are usually lubricated with periodic oil or grease during human operation. The lubrication of reducers also has its own conditions, and the lubrication conditions for different reducers are also different.

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 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 height of the gear immersed 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.

The above is about the maintenance and lubrication of the gear and rack of the reducer. If you have any other questions, please contact us in a timely manner!
