DUAL-MOTOR SYNCHRONOUS DRIVE OF DRUM MILL

摘要

The present invention relates to the devices that allow to evenly distribute the load among multiple power flows such as in dual-motor synchronous drives of drum mills. A dual-motor drive of a drum mill comprises synchronous motors, which are connected to an open gear by pinion gears and clutches and hydraulic balloon clutches that are hydraulically connected to hydropneumatic accumulators. According to the invention, the hydraulic parts of hydropneumatic accumulators are interconnected with the hydraulic system of each of the hydraulic balloon clutches, whereas the hydropneumatic accumulators are installed stationary and separately from the drive shafts. The invention provides a uniform load distribution between two synchronous motors in the drum mill drive.
