The lubrication system of the parallel twin-screw gearbox is very important for the normal operation of the gearbox. The large-scale wind power gearbox must be equipped with a reliable forced lubrication system to lubricate the gear meshing area and bearings during operation. . Lubricating oil temperature is related to component fatigue and overall system life. Generally speaking, the maximum oil temperature of the gear box should not exceed 80 °C during normal operation, and the temperature difference between different bearings should not exceed 15 °C.
When the parallel twin-screw gearbox is operated, when the oil temperature is higher than 65 degrees, the cooling system will start to work. When the oil temperature is lower than 10 °C during operation, the lubricating oil should be heated to the predetermined temperature first. Boot up. Gearbox lubricants have an optimum temperature range for operation. It is recommended to design a lubricant thermal management system for the gearbox lubrication system: when the temperature exceeds a certain value, the cooling system starts to work. When the temperature is lower than a certain value, the heating system starts to work. Always keep the temperature within the optimal range.
Parallel twin-screw gearboxes improve the quality of lubricants and are an important aspect of lubrication systems. Lubricant products must have excellent low-temperature fluidity and high-temperature stability. Research lubrication and cooling of high-performance lubricants should be strengthened.
