How to lubricate the gear cycloid reducer?Regarding the lubrication of the reducer, it is also a very important link for the maintenance of the reducer.Open and semi-open gear cycloid reducer drives, or closed gear drives with lower speeds, are usually lubricated periodically by manual work, and the lubricant used is lubricating oil or grease.The lubrication of the cycloid reducer also has its own conditions, and the lubrication conditions for different cycloid reducers are also different.
When the peripheral speed of the gear of the cycloid reducer is greater than 12m/S, oil injection lubrication should be used, that is, oil is supplied by the oil pump or the central oil supply station at a certain pressure, and the lubricating oil is sprayed to the gear teeth by the nozzle. on the countertop.When v≤25m/s, the nozzle can be located on the side of the gear teeth meshing in or out; when v>25m/s, the nozzle should be located on the outgoing side of the gear teeth, so as to cool the newly meshed gear in time with lubricating oil. The gear teeth are also lubricated.
The general closed gear reducer transmission, the lubrication method is determined according to the circumferential speed of the gear.When the peripheral speed of the gear V<12m/s, the gear teeth of the large gear are often immersed in the oil ground for oil immersion lubrication.In this way, when the gear is in transmission, the lubricating oil is brought to the meshing tooth surface, and the oil is also thrown to the wall of the box to dissipate heat.The depth of the gear immersed in the oil depends on the circumferential speed of the gear. For cylindrical gears, it is usually not more than one tooth height, but generally it should not be less than 10mm; for bevel gears, it should be immersed in the full tooth width, at least immersed in the tooth width. half.In the multi-stage gear transmission, the oil can be brought to the tooth surface of the gear that is not immersed in the oil ground by means of an oil tanker.
The amount of oil in the oil pool depends on the transmission power of the gear.For single-stage transmission, the oil demand is about 0.35~0.7Lo for every Ikw of power transmitted. For multi-stage transmission, the oil demand increases exponentially according to the number of stages.
