What are the factors affecting the temperature rise of gear reducer?

The reducer can reduce the speed of the motor and increase the output torque. As a supporting part, reducer is used in hoisting, construction and other industries. So what are the factors that affect the temperature rise of gear reducer in daily operation?
The factors affecting the temperature rise of gear reducer are as follows:
1. The viscosity of the selected gear oil is too high, causing difficulty in heat dissipation. Because the heat transfer effect of high viscosity oil is worse than that of low viscosity oil, the temperature rise will be significantly higher than that of low viscosity oil.
2. The newly installed gearbox needs a certain running in time, which causes the temperature rise of the gear surface of the reducer. This temperature rise is a necessary stage for the normal operation of the equipment.
3. Excessive oil filling and high oil level affect the normal heat dissipation of reducer gear. Note: too much or too little oil will affect the heat dissipation effect.
4. The gearbox of the reducer is overloaded, the oil film is broken, and there is a tendency of wear and failure.
The reducer is applicable to metallurgy, miners, transportation, petrochemical, light industrial machinery, etc., especially to make breakthroughs and progress in the field of continuous transmission, from the unification of the internal gearbox of the reducer.
