  • Geared drive unit for imparting motion to a load
    Patent number: 5833569
    Abstract: A drive train for transmitting torque produced by a motor to a load comprises a planetary gear arrangement mounted concentrically with respect to a tubular shaft. The planetary gear arrangement cooperates with a pair of driven gears which are also coaxial with the tubular shaft, the planetary gear arrangement and the pair of gears being located within an outer housing. The tubular shaft provides an unobstructed, large diameter passage through the drive train, the passage being available for the routing to a load connected to one of the driven gears of movable shafts, conduits or electrical conductors.
