MULTI-ELECTRIC MOTOR DRIVEN SYNCHRONOUS GEARBOX ASSEMBLY WITH MOTOR FAILURE MECHANISM

摘要

A multi-electric motor driven gearbox assembly includes a main gear coupled to at least two pinion gears. Each pinion gear is connected via an associated secondary shaft to corresponding secondary shaft pulleys that are adapted to be driven by an electric motor. A one-way bearing is coupled to each pinion gear and disposed so as to allow the pinion gear to decouple relative to the secondary shaft pulley when the associated electric motor fails and to do so without creating drag on the main gear during decoupling.
