The invention discloses an oil-electric
hybrid power input ship gearbox. The oil-electric
hybrid power input ship gearbox mainly comprises an ahead running driving gear and a back running driving gear, wherein the ahead running driving gear and the back running driving gear are meshed with an output gear; the output gear and an output shaft
coupling are fixedly arranged on an output shaft; a motoris arranged on a main box and is connected to a motor input shaft; a motor
clutch shell is fixedly arranged on the motor input shaft; and a motor driving gear connected in a motor
clutch is meshed with an input transmission gear. A gearbox hydraulic
system controls a
diesel engine to work on the gearbox through the combination of
diesel engine clutches, and controls the motor to work on the gearbox through the combination of the motor clutches. When a right
piston in the input transmission gear and a back running
piston in the back running transmission gear do not work, the clutches for controlling the
diesel engine are combined, and the clutches for controlling the motor are combined, that is, the diesel engine drives the motor, generates
electricity for the motor and charge the motor, and thus, a generator set is formed. The oil-electric
hybrid power input ship gearbox has compact structure and wide applicability, is energy-saving and environmentally-friendly, and is safe and reliable in use.
