- Brief Summary
The External Mounted Electric Motorized Pulleys is a new type of driving device which puts the motor and the reducer together in the drum body. It is mainly used in stationary and mobile belt conveyor, alternative to the traditional motor, the reducer in the driving drum outside of the separate driving device.
The common application environment of External Mounted Electric Motorized Pulleys is common, corrosive, flammable and explosive. If subdivided there are high temperature, hot and humid zone and some special use occasions, but the number of electric drum used in these occasions is not much, generally only as a non-standard electric drum production.
The External Mounted Electric Motorized Pulleys has many advantages, such as compact structure, high transmission efficiency, low noise, long service life, stable operation, reliable operation, good sealing, small space occupied, convenient installation and so on, and is suitable for working under various adverse environmental conditions.
- Cooling mode
This kind of electric drum is also called indirect oil-cooled electric drum. There is a certain amount of cooling oil in the electric drum. As the External Mounted Electric Motorized Pulleys body keeps rotating, the oil scraper on the drum body continuously pours the oil on the motor and gear, taking away the heat generated by the motor and gear when they work, transferring the heat to the drum body wall, accelerating the heat dissipation of the motor and lubricating the gear. The key of the oil-cooled electric roller is that the oil inside the motor is not allowed to enter.
- Transmission Device
At home and abroad, the most commonly used reducer device of External Mounted Electric Motorized Pulleys is the fixed shaft gear transmission, and more than 95% of the gear transmission is the transmission structure of the fixed shaft involute cylindrical gear. The transmission has the advantages of simple structure, reliable performance, easy manufacture, convenient installation and maintenance, high efficiency and low noise. Commonly used two deceleration, a small number of three deceleration.
This series of External Mounted Electric Motorized Pulleys is completely sealed. In the case of no special declaration, the motors are generally Y series motors with class B insulation and protection grade of IP44. The voltage is 380V, the frequency is 50HZ, the altitude is not more than 1000 meters, and the ambient temperature is not more than 40 degrees.
