Precision gear factory tutor you how to lubricate the gear reducer

How to lubricate the gear reducer. The lubrication of the reducer is also a very important link for the maintenance of the reducer. Open and semi-open gear reducer drive, or low speed closed gear transmission, usually human work periodic refueling lubrication, the lubricant is lubricating oil or grease. The lubrication of speed reducer also has its own conditions, for different speed reducer lubrication conditions are also different. Here's a look at how the precision gear manufacturers do the gear reducer lubrication.

When the circumference speed of the gear of the reducer is> 12m / S, oil injection lubrication should be used, that is, the oil pump or the central oil supply station at ~ fixed pressure, and the lubricating oil should be injected to the gear surface by the nozzle. When v 25 m/s, the nozzle is located on the side of the gear; when v> 25 m/s, the nozzle should be located on the side of the gear and lubricate the gear.

General closed gear reducer drive, its lubrication method depends on the circumference speed of the gear. When the circumference speed of the gear is V <12 m/s, the wheel teeth of the large gear are often immersed in the oil field for oil immersion lubrication. In this way, when the gear drives, it brings the lubricating oil to the engaged tooth surface, and also throws the oil to the box wall, so as to dissipate heat. The depth of the gear in oil can be based on the circumference speed of the gear, but generally not less than 10mm; the bical gear should be immersed in the full tooth width, at least half the tooth width. In a multistage gear transmission, the oil can be carried to the tooth surface of the gear not immersed in the oil field.

The amount of oil in the oil tank of the gear reducer depends on the size of the gear transmission power. For single-stage transmission, the power demand of Ikw is about 0.35~0.7Lo. For multi-stage transmission, the oil demand is doubled by series.
