Precautions for the use of lubricants for precision planetary reducers
Selection of grease When selecting grease according to the bearing load of the planetary reducer, grease with a small needle penetration should be selected for heavy loads. When working under high pressure, in addition to small penetration, it also needs to have high oil film strength and extreme pressure performance. When selecting grease according to environmental conditions, calcium-based grease is not easy to dissolve in water and is suitable for dry and less-moisture environments.
When selecting grease according to the working temperature, the main indicators should be the dropping point, oxidation stability and low temperature performance. The dropping point can generally be used to evaluate the high temperature performance, and the actual working temperature of the bearing should be 10-20°C lower than the dropping point. The operating temperature of synthetic grease should be 20-30°C lower than the dropping point.
It is forbidden to mix different lubricating oils with each other. The location of the oil level plug, oil drain plug and breather is determined by the installation location. Their relative positions can be determined by referring to the installation position diagram of the reducer.
