ABSTRACT:
A hydraulic motor encased with a pulley drives the pulley and thereby drives a belt conveyor. The motor is encased in a stationary housing and is driven by fluid pumped from an external source through a stationary first shaft into the interior of the pulley. The first shaft and a second stationary shaft are supported by brackets which sustain the weight of the assembly. The pulley revolves on bearings on the two shafts. The inner end of the first shaft is supported by one end of the motor housing and the inner end of the second shaft by bearings in a drive flange which is fixed to the motor shaft and to an internal partition of the pulley. The partition is apertured and communicates with a discharge duct in the second shaft so that fluid leaking in the interior of the pulley is discharged.
