Problems solved by technology

[0002] The existing electric drums are all "motor-reducer" structures, which are divided into internal and external electric drums. Since the "motor-reducer" structure is driven by gears, thermal power loss will occur during the transmission process, reducing transmission efficiency.
The existing high-power electric drums are all in the form of oil cooling, which needs to be replaced for maintenance after 5000 hours of operation

Abstract

The invention relates to an air cooled structure permanent magnetic full-electric drive roller. A hollow shaft is fixedly connected with a stator through a taper-lock. A winding coil cable on the stator is connected with a junction box on the end portion of the hollow shaft through a center hole in the hollow shaft. The two ends of the hollow shaft are provided with a connection disk I and a connection disk II through bearings. A permanent magnetic rotor is located on the outer circumference of the stator and connected with the connection disk II through a bolt. A roller body is connected withthe connection disk I and the connection disk II through bolts. A cavity formed among the roller body, the connection disk I and the connection disk II is internally provided with an air cooled heatdissipation system. The air cooled structure permanent magnetic full-electric drive roller adopts a permanent magnetic full-electric drive roller structure, a mechanical gear reducer is removed, the transmission efficiency is improved, and the energy consumption is reduced.

Description

technical field [0001] The invention relates to an air-cooled structure permanent magnet all-electric driving drum, which is applied to equipment such as belt conveyors and hoists as a power source. Background technique [0002] The existing electric drums all have a "motor-reducer" structure, which is divided into internal and external electric drums. Since the "motor-reducer" structure is driven by gears, thermal power loss will occur during the transmission process, reducing transmission efficiency. The existing high-power electric drums are all in the form of oil cooling, which needs to be replaced for maintenance after 5000 hours of operation. Contents of the invention [0003] The technical problem to be solved by the invention is to provide an air-cooled structure permanent magnet all-electric drive drum, which adopts a permanent magnet all-electric drive drum structure, cancels the mechanical gear reducer, and improves the Transmission efficiency reduces energy co...
