[0002] The electric drum is a new type of drive device that places the motor and reducer together inside the drum body. The principle of the electric drum is that after the motor is powered on, the power generated is transmitted to the reducer, and after the deceleration and torque increase of the reducer, the power is transmitted to the drum, causing the drum to rotate, thereby driving the conveyor belt or other driven parts to move.

Among them, the existing water-cooled electric rollers have a complex structure and are difficult to install and maintain. A large amount of coolant is required for cooling. The subsequent discharge of the coolant is also not conducive to environmental protection, and its cooling system is also prone to leakage and other problems. In a high temperature and high load working environment, the air-cooled electric roller will have poor heat dissipation, resulting in excessive temperature and affecting performance.

The cavity wall of the sealed cavity is connected to the outer wall of the heat dissipation channel through an annular plate. The annular plate is evenly provided with a plurality of small channels running through its two ends, and a heat dissipation fan is correspondingly arranged at the end of each small channel.
