With the rapid development of China's industry, the role of electric drum in national production is increasing, and the main design aspect of its products is the design of transmission structure and overall layout. In China, the development of electric rolling is relatively late, but the development is very fast. At present, the electric drum has been widely used in mining and metallurgy, coal, transportation, energy, food, tobacco, chemical industry, building materials, post and telecommunications, aviation, agriculture and forestry, printing, commerce and other production and construction fields.
The electric drum is a new type of driving device that places the motor and the deceleration mechanism in the drive drum, which is mainly used in fixed and mobile belt conveyors, replacing the traditional open drive device of the motor and reducer outside the drive drum. In addition, it is also widely used as a driving roller on the conveyor to convey finished goods. After entering the 80s, the application of electric drum has expanded with each passing day.
Compared with the traditional open drive device, the electric drum has the advantages of compact structure, high efficiency, less energy consumption, low noise, long life, stable operation, reliable work, good sealing, less space occupation, convenient installation and maintenance, etc., and is suitable for working in various environments, including dusty, wet and muddy harsh working environments, and special flameproof electric drums can also work in flammable and explosive environments. Therefore, at present, electric rollers have been widely used in various fields of the poor economy at home and abroad.
China developed the first electric drum in May 1961, about ten years later than the development and development of China's belt conveyor, and more than 30 years later than the birth of the world's first electric roller, but since the mid-70s, especially in the 80s, electric roller has developed rapidly in China. In the 90s, through the introduction of technology digestion, absorption and independent development of China's electric rollers, both in terms of varieties and specifications, or in terms of performance indicators, have caught up with or exceeded the world's advanced level.
