Disclosed are a propulsion system for a ship, a method of assembling the same, and a method of disassembling the same. The propulsion system for the ship includes: a rear propeller fixed to a rotary shaft; a front propeller that is rotatably supported on the rotary shaft in front of the rear propeller; a contra-rotating device that is mounted in an installation space at a rear end of a hull so as to reverse the rotation of the rotary shaft and transmit the reversed rotation to the front propeller; a propeller connecting member that connects the contra-rotating device and the front propeller to transmit a rotational force; and a thrust supporting device that is provided between the contra-rotating device and the propeller connection member to support thrust of the front propeller.

An outboard motor comprising a power transmission mechanism transmitting the power of an engine to a propeller. The transmission unit of the power transmission mechanism comprises a one row of planetary gear train for transmission having a sun gear for transmission, planetary gears for transmission, and an internal gear for transmission. The internal gear for transmission is connected to an engine side input shaft, the planetary gears for transmission are connected to a propeller side output shaft, the sun gear for transmission is connected to a fixed part through a one-way clutch, and the planetary gears for transmission, the internal gear for transmission, and/or the sun gear for transmission are connected to each other through an engagement/disengagement clutch. Accordingly, when the engagement/disengagement clutch is disengaged, the one-way clutch is engaged, and the speed of the input shaft is reduced and output from the output shaft. When the engagement/disengagement clutch is engaged, the one-way clutch is disengaged, and the speed of the input shaft is output from the output shaft at a same speed.

The invention relates to a marine propulsion system comprising an upper housing part, a pod and a shank which extends between the upper housing part and the pod. An underwater gearbox having an input shaft and an output shaft is arranged in the pod. Thee input shaft is connected to a driveshaft that extends through the shank, said driveshaft being driven by a motor. Said motor is mounted inside the shank and surrounds the driveshaft.

摘要:
A rudder propeller including a drive shaft and a propeller shaft that can be driven by the drive shaft by an angular drive and a planetary gear that can be located on the propeller shaft and including a sun gear that is connected to the angular drive via a coupling, a fixed ring gear and planet gears that revolve between the sun gear and ring gear and that are mounted on a planet carrier. The planet carrier can be secured against torque to the propeller shaft and the coupling between the angular drive and the sun gear can be designed as a double cardanic, rotationally-fixed flexible coupling, in such a way that radial and angular displacements of the sun gear in relation to the angular drive can be compensated.

In an outboard motor having a power transmission mechanism for transmitting power of an engine to a propeller, the power transmission mechanism has a transmission ratio changing unit having a transmission ratio changing planetary gear train including a transmission ratio changing sun gear, transmission ratio changing planetary gears, and a transmission ratio changing internal gear. The transmission ratio changing internal gear is connected to an input side shaft on the engine side. The transmission ratio changing planetary gears are connected to an output side shaft on the propeller side. The transmission ratio changing sun gear is connected to a stationary portion via a one-way clutch. The transmission ratio changing planetary gears and the transmission ratio changing internal gear and/or the transmission ratio changing sun gear are connected by an on-off clutch. When the on-off clutch is disengaged, the one-way clutch is engaged and the speed from the input side shaft is outputted from the output side shaft with a reduced speed. When the on-off clutch is engaged, the one-way clutch is disengaged and the speed from the input side shaft is outputted from the output side shaft with the same speed.
