合もある。2. Description of the Related Art A ship is provided with a main generator for generating electric power used for various auxiliary machines and lighting and an auxiliary generator for backing up the main generator. These generators are often driven by a prime mover such as a diesel engine, but there are also ships equipped with a main shaft drive generator that is connected to a main shaft that drives a propeller by gears and is driven by the main shaft. Further, some ships require low speed and low vibration sailing in addition to normal sailing speed. For example, there are times when an observation ship is operating for observation or when leisure boats are operating at a low speed, and when the main engine fails, low speed navigation may be required.

歯車の２重化、装備スペースの必要が生じる。When operating at low speed and low vibration, the propeller shaft is driven by a prime mover different from the main engine. A motor that is easy to control and compact is used as the prime mover, and the rotational force is transmitted to the propeller shaft via gears. Conventionally, there is not a case where a main shaft drive generator is provided and a low speed operation is supplementarily performed by an electric motor, but when realizing this,
Two gears are provided on the main shaft, one of which is connected to the main shaft drive generator and the other of which is connected to the electric propulsion electric motor. For this reason, it is necessary to double the gears and to install space.

FIG. 2 is a configuration diagram showing the power transmission relationship of FIG. A main engine 2 is provided on the bottom of the ship in the center of the hull 1, and a main shaft 3 is rotationally driven to rotate a propeller 4. The main shaft 3 and the main machine 2 are connected by a main joint 5. A diesel engine is often used as the main engine 2, but a gas turbine may also be used. The main joint 5 is composed of a clutch, and disconnects the main engine 2 and the main shaft 3 when disconnecting. A first gear 6 is fixed to the main shaft 3, and a second gear 7 is meshed with the first gear 6. Spindle generator 10
Is directly connected to the shaft of the second gear 7, and the electric motor 11 is connected to the second gear 7 via the clutch 9. Spindle generator 1
For 0, a synchronous generator is used. Main shaft generator 10 is main unit 2
Since the electric power is generated only during the cruising, the auxiliary power generator (not shown) is provided as a power source during the low speed operation by the electric motor 11 or during the berth. An induction motor is used as the electric motor 11, and electric power is supplied from the auxiliary generator.

The spindle generator 10 is driven via the first gear 6 and the second gear 7 to generate electric power. During this time, the clutch 9 is disengaged and the electric motor 11 does not rotate. When shifting to low speed operation or when the main engine 2 fails, the main joint 5 is disconnected and the clutch 9 is connected. The spindle generator 10 disconnects the exciting current and the power generation end. Electric power is supplied to the electric motor 11 from an auxiliary generator. As a result, the main shaft 3 is rotated via the second gear 7 and the first gear 6, and the propeller 4 is rotated to travel at a low speed.

The installation space can be reduced. Further, since only the main shaft generator is connected to the second gear and the third gear that meshes with the first gear is provided and the electric motor is connected to this, the degree of freedom of arrangement of the electric motor is increased.
