Abstract
The present invention relates to the field of hoisting drive systems for power shovels, and particularly to a reducer with balanced output of a very large torque from a plurality of motors, including a first motor shaft, a second motor shaft, a third motor shaft and a fourth motor shaft, which are each drivingly connected to the plurality of motors. In addition to outputting a very large torque employing the plurality of motors with the reducer, the reducer of the present invention can ensure that the output is balanced and stable, remarkably enhancing performance, safety and stability of a hoisting drive system for a power shovel. Adjustable motor transmission assemblies assembled on exterior lateral surfaces of the first motor shaft, the second motor shaft, the third motor shaft and the fourth motor shaft can adjust the number and locations of power transmission grooves according to the number and locations of actually active motors, greatly increasing applicability. Such adjustments are accomplished by a compact and sensible internal layout and design, without affecting external power transmission or heat dissipation spaces.
