Common gearbox lubrication methods include gear oil lubrication, semi-fluid grease lubrication, and several methods of solid lubricant lubrication. For better sealing, high speed, large load, good sealing performance can use gear oil lubrication; for the poor sealing, low speed can use semi-fluid lubrication lubrication; for oil-free applications or high temperature applications can be used two Molybdenum sulfide ultrafine powder lubrication.
