When the planetary reducer operates like other reducers, it needs to be lubricated to not only accelerate the operation of the planetary reducer, but also protect its normal operation. How to do a good job of lubrication for planetary reducers? Let's take a closer look at the detailed explanation below.
When selecting lubricating grease based on the bearing load of the walking planetary reducer, lubricating grease with small needle penetration should be selected for the load. When working under high pressure, in addition to low needle penetration, it also requires high oil film strength and extreme pressure performance.
When selecting lubricants based on environmental conditions, calcium based lubricants are not easily soluble in water and are suitable for dry and low moisture environments. When selecting lubricating grease based on working temperature, the main indicators should be the drop point, oxidation stability, and low-temperature performance. The drop point can generally be used to evaluate high-temperature performance, and the actual working temperature of the bearing should be 10-20 ℃ lower than the drop point. The usage temperature of synthetic lubricating grease should be 20-30 ℃ lower than the drop point.
The lubrication method of planetary reducers is also one aspect that causes poor lubrication. Splash lubrication is mainly used in high speed situations, and is obviously not suitable for situations with medium loads and low speeds. Closed full life gearboxes with long lifespan and less maintenance can be used for lubrication of boiler feed in gearboxes, chain continuously variable transmissions, planetary reducers, and centralized grease supply equipment.
