The gearbox lubriing oil has the optimal temperature range for operation. It is recommended to design a lubriing oil thermal management system for the gearbox lubriion system: the cooling system starts working when the temperature exceeds a certain value, and the heating system starts working when the temperature drops below a certain value, always controlling the temperature within the optimal range. In addition, improving the quality of lubriing oil is also an important aspect that must be considered in the lubriion system. Lubricant products must have excellent low-temperature flowability and high-temperature stability, and research on high-performance lubricants should be strengthened.
