  • Drive unit for machinery, especially mining machinery
    Patent number: 6267211
    Abstract: A drive unit for a mining machine such as a mining plow or conveyor drives a sprocket wheel of the chain thereof by an electric motor through a drive train having a turbocoupling and a transmission driven by the motor. A free-shifting clutch is provided in the case of overload to disconnect the load from the motor, the clutch reengaging upon standstill of the two clutch halves. Alternatively the turbine output of the fluid coupling is branched and is applied through one friction clutch directly to the input shaft of the transmission or through a second friction clutch to a parallel shaft connected by gearing to the transmission input shaft.
