ABSTRACT:
A drive mechanism for a tilting-pan filter assembly comprises an annular carrier for supporting a plurality of filter pans for motion along a circular transport path. The carrier is moved along the circular path by drive componentry including a plurality of individual hydraulic motors having pinions meshing with a ring gear on the carrier at respective equispaced drive points. The hydraulic motors are driven by a single pump which supplies a hydraulic fluid under variable pressure and variable flow rate. The hydraulic motors are connected in parallel to one another and to the pump in a closed loop hydraulic circuit. The pump may be driven by an electric motor which absorbs braking energy.
