Abstract: In adjustment of synchronization of singledrum doublemotor drive, the adjustment value of side clearance of the gear pair is different from that of singledrum singlemotor drive, and the side clearance of the gear pair must be enlarged properly to ensure the large gear and small gear to mesh correctly; and by adding the electrical compensation, the synchronization of doublemotor drive and synchronization of two hoisting points can be realized. 

Key words: single-drum double-motor drive, adjustment value of gear pair side clearance, synchronization of double-motor drive, synchronization of two hoisting points
