The smoothness of the reducer is also a very important link in the maintenance of the reducer. Open and semi-open gear reducer transmission, or low-speed closed gear transmission, ordinary people work periodically refueling smooth, smooth agent for smooth oil or smooth grease.

The smoothness of the reducer is also a very important link in the maintenance of the reducer. Open and semi-open gear reducer transmission, or low-speed closed gear transmission, ordinary people work periodically refueling smooth, smooth agent for smooth oil or smooth grease. The smoothness of the reducer also has its own conditions, and the smoothness conditions of different reducers are also different.


When the peripheral speed of the reducer gear is> 12, the m/S oil injection should be smooth, that is, the oil pump or the central oil supply station uses ~ constant pressure oil supply, and the smooth oil is sprayed on the gear meshing table with a nozzle. v ≤ 25 m/s when the nozzle is at the gear tooth meshing edge or outpost edge; when the nozzle is at the gear tooth meshing edge or outpost edge; v>25 m/s The nozzle should be located on the outpost side of the gear tooth, so that the smooth oil can cool the newly meshed gear tooth in time and stop the gear tooth from smoothing.


The transmission method of the universal closed gear reducer depends on the peripheral speed of the gear. When the peripheral speed of the gear. When V<12 m/s, the gear of the large gear is often immersed in the oil, and the soaking is stopped. In this way, when the gear is driven, the smooth oil is brought to the surface of the meshing teeth, and the oil is thrown onto the wall of the box to dissipate heat. The depth to which the gear is immersed in the oil depends on the peripheral speed of the gear. Cylindrical gears generally do not exceed the tooth height, but generally not less than 10mm; bevel gears should be immersed in the full tooth width, at least half of the tooth width.


In a multi-stage gear drive, the oil can be tanker to bring the oil to the surface of the gear that is not immersed in the oil. The amount of oil in the oil pool depends on the size of the gear transmission power. For single-stage transmission, the oil demand is about 0.35 ~ 0.7Lo for each transmission of Ikw power. For multi-stage transmission, the oil demand increases exponentially according to the number of stages.
