Product Description

An electric drum is a new - type driving device that integrates an electric motor and a speed reducer inside the drum body. It is mainly used in fixed and mobile belt conveyors, replacing the traditional driving form with a separate electric motor and speed reducer.
 
Structure and Principle
 
- Structure: Generally, it consists of a drum body, an electric motor system, a speed - reducing mechanism, bearings, and seals. The drum body is usually made of high - strength alloy steel or stainless steel and can be rubber - covered. The electric motor is mostly a three - phase asynchronous motor or a DC brushless motor. The speed - reducing mechanism has forms such as planetary gears and helical gears. Bearings and seals ensure the equipment is dust - proof, waterproof, and operates stably.
 
- Working Principle: After the electric motor is powered on, it rotates at a high speed. The power is transmitted to the speed - reducing device through a coupling. The speed is reduced and the torque is increased through transmission components such as gears, and then the power is transferred to the drum body, driving the conveyor belt and materials to move. Moreover, the speed and torque of the electric motor can be adjusted as required by the control system.
 
Classification
 
- By Cooling Method: Air - cooled type dissipates heat through conduction, radiation, and air convection, and is divided into forced air - cooling and natural air - cooling. The oil - cooled type (indirect oil - cooling) has a cooling oil inside, and the oil is poured by a scraper for heat dissipation and lubrication. In the oil - immersed type (direct oil - cooling), the oil is allowed to contact the motor windings for heat dissipation, which has high requirements for the quality of the oil and the motor.
 
- By Transmission Structure: The fixed - axis gear transmission has a simple and reliable structure, is convenient for manufacturing and maintenance, and is widely used. The planetary gear transmission is small in size and large in load - bearing capacity, but inconvenient for maintenance. The cycloidal - pinwheel transmission is a characteristic structure that can achieve a small linear speed and high - power output.
 
- By Application Environment: It covers ordinary, corrosive, flammable, and explosive occasions, as well as special scenarios such as high - temperature and wet - tropical areas. Most of them are non - standard types.
 
Features and Advantages
 
It has the advantages of a compact structure, high transmission efficiency, low noise, long service life, smooth operation, reliable work, good sealing, small occupied space, and convenient installation. It can work stably in harsh environments such as damp, muddy, and dusty conditions, and it is also easy to achieve centralized control, meeting the functional requirements of backstop, braking, rubber - covering, etc.
 
Application Fields
 
It is widely used in industries such as mining, metallurgy, chemical industry, coal, building materials, electric power, grain, and transportation. It is the power source of belt conveyors, lifting equipment, etc., and can convey bulk materials (such as coal, ore, etc.) and unitized goods (such as hemp bales, equipment, etc.).
