Generally speaking, it refers to a device with a large tooth (disk) with a large tooth (disc). The driving wheel is high speed, the driven wheel becomes low speed, and the energy transmission from active to driven can be direct coupling of teeth-tooth. Coupling through belts and chains to achieve the goal of switching from high speed to low speed.
The reasons for the excessive oil temperature in Taichuang Motor are:

a. The lubricant is unqualified or used for too long.
b. Too much lubricating oil is not conducive to heat dissipation in the gearbox.
c. The parts are damaged. Damage to the components includes severe gear pitting, broken teeth, bearing cages, inner and outer rings, ball damage, and bearing locks or severe shaft deformation.
d. The outside of the cabinet is covered with debris or dust. When things are stacked around the motor or the surface of the machine has not been cleaned for a long time, the heat of the reducer may be incomplete due to the covering of debris or dust, so that the oil temperature rises.
e. The cooling unit is clogged or fails. The cooling device is placed in a dusty factory like the motor. If the internal pipeline is not cleaned for a long period of time and the cooling device is blocked or the cooling device is broken, the motor oil temperature will rise.
