Lubrication Technology of Metallurgical Gear Reducer

1. Select lubricating oil of appropriate quality
If the gear reducer is to bear a higher load and operate in a cycle, it is necessary to use lubricating oil to complete the necessary improvement of anti-oxidation ability, which is more durable and will not change much, and is prone to deposited water and pollution components.Selected cycle oils are usually better.It contains anti-oxidation and anti-rust additives.Cycle oil has better oxidation resistance, durability and rust resistance.And you can also choose to have anti-wear components or extreme pressure additives, which are extreme pressure oil materials.
2. Application of reducer lubricating oil or grease
For several gear reducers, the choice of reducer oil or grease can better complete the lubrication.But we need to choose * * * fuel efficient and * * * cost-effective.Generally speaking, oil with a better lubricating coefficient can be used for heat dissipation of lubricating oil.The friction coefficient is small, the use is more convenient, and the oil film is more symmetrical.
For lubricating grease, it has the characteristics that lubricating oil does not have: the machine does not need to be lubricated and drips oil; if the oil deflecting ring is relatively perfect, the lubricating grease is not easy to leak and does not need to be refueled; at higher temperatures, the lubricating grease is not easy to change Thin; the grease itself has the effect of protecting the bearing; in places where it is not easy to add oil, extend the smoothing cycle; assuming the oil retainer is good, it can also prevent the entry of pollutants.
3. Lubrication method Selection
The method of lubrication also affects the choice of lubricant.Refueling through circulating oil supply capacity and oil ring oil supply method, the oil is not only used back and forth in the lubricating system of the gear reducer, but also generally dispersed into small oils and exposed to air, which is prone to oxidation.* * * Less oil also needs to use higher quality and more durable oil, such as circulating oil, etc., with good anti-oxidation ability and anti-rust additives, which have good anti-oxidation ability and good anti-corrosion and anti-rust ability.
4. Oil viscosity control
Viscosity is what achieves the perfectly smooth * * * essence.It's just that the viscosity is not enough, and it is easy to cause conflicts between metals.The resistance in high viscosity lubricating oil is not very good.Generally speaking, it is enough to choose the low viscosity required by the specific reducer, and the viscosity should not be too thick.Viscosity requirements are affected when the temperature difference of the lubricated part and the journal speed, load and spacing of the lubricated part are changed.
