  • Conveyor gear with return lock
    Patent number: 7134356
    Abstract: The invention relates to a gear for conveyors which has a drive shaft to which a drive motor is to be fastened as well as an output shaft with which the gear is connected to the conveyor. However, at least one gear step is provided within the gear. Moreover, the gear is provided with a freewheel locking in one direction of rotation. A second gear step is provided in this case between the freewheel and the elements transmitting torque between drive and output shaft during normal operation, so that the freewheel should be operated at a higher speed and must only provide a low holding moment in the event of a stoppage.
