How to lubricate the gear reducer of the motor?
Author:
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 pump oil supply station supplies oil with a certain pressure, and the lubricating oil is sprayed onto the meshing surface of the gear teeth by the nozzle. When v≤25m/s, the nozzle can be located on the side where the gear teeth are engaged or on the whistle side; when v>25m/s, the nozzle should be located on the side where the gear teeth whistle out, so that the newly meshed gear can be cooled in time by lubricating oil. The gear teeth are also lubricated.
General closed gear reducer transmission, the lubrication method is determined according to the peripheral speed of the gear. When the peripheral speed of the gear is V<12m/s, the gear teeth of the large gear are often immersed in oil for oil immersion lubrication. In this way, when the gear is in transmission, the lubricating oil is brought to the meshing tooth surface, and at the same time, the oil is thrown to the box wall to dissipate heat. The depth of the gear immersed in the oil depends on the peripheral 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; half. In multi-stage gear transmission, oil can be brought to the tooth surface of the gear that is not immersed in the oil field by means of a belt tanker.
The amount of oil in the oil pool depends on the power transmitted by the gear. For single-stage transmission, the oil demand is about 0.35~0.7Lo for every 1kw of power transmitted. For multi-stage transmission, the oil demand increases exponentially according to the number of stages.
