Abstract
A high-speed drive shaft is connected to dredge pump shaft by a planetary gear, upon which a controlled speed is superposed, by branching power off the high-speed shaft for driving an auxiliary adjustable pump which, in turn, runs a hydrostatic motor whose rotary output is connected to the ring gear of the planetary gear via a transmission which includes two brakes and a speed-responsive clutch; one brake is also speed-responsive, the other one is responsive to motor pressure, to provide a possibly redundant system for preventing torque transmission to the motor, e.g., in case of dredge pump blockage.
