The lubrication method of the gearbox is molybdenum disulfide. LFB series Harmonic Gearbox manufacturer tells you that the commonly used gear box lubrication methods include gear oil lubrication, semi-fluid grease lubrication, and solid lubricant lubrication.

LFB series Harmonic Gearbox manufacturer tells you that gear oil can be used for lubrication with good sealing, high speed, large load, and good sealing performance; semi-fluid grease can be used for poor sealing and low speed; Molybdenum disulfide ultrafine powder can be used for lubrication in oil or high temperature applications.
LFB series Harmonic Gearbox manufacturer tells you that the lubrication system of the gearbox is of great significance to the normal operation of the gearbox. Large wind turbine gearboxes must be equipped with a reliable forced lubrication system to lubricate the gear meshing area and bearings. Insufficient lubrication accounts for more than half of the reasons for gearbox failure.
LFB series Harmonic Gearbox manufacturer tells you that lubricating oil temperature is related to component fatigue and the life of the entire system. Generally speaking, the maximum oil temperature of the gearbox should not exceed 80℃ during normal operation, and the temperature difference between different bearings should not exceed 15℃. When the oil temperature is higher than 65℃, the cooling system starts to work; when the oil temperature is lower than 10℃, the lubricating oil should be heated to the predetermined temperature before starting.
The above information is the FB series Harmonic Gearbox manufacturer's introduction and analysis of the lubrication method of the gearbox, hope it helps you.
