Abstract
An electric power generating equipment (10) is provided between an internal combustion engine (2) and a power transmission device (3), and an electric motor (9) is disposed at an area of the power transmission device. An output shaft (9a) of the electric motor (9) is disposed coaxially to any of rotary shafts of the power transmission device (3).
Claims20
A power generating and propelling system of a vessel, comprising:
- an internal combustion engine;
- a power transmission device;
- an electric power generating equipment provided between the internal combustion engine and the power transmission device;
- and
- an electric motor disposed at an area of the power transmission device, wherein the power transmission device is selectively driven by the internal combustion engine independently, by the electric motor independently, or by the internal combustion engine and the electric motor collectively.
2 more elements
A power generating and propelling system of a vessel comprising:
- an internal combustion engine having a substantially horizontal crankshaft;
- a power transmission device having an input shaft, which is substantially coaxially connected to the crankshaft, and a substantially vertical transmission shaft;
- a propeller shaft having a height different from the input shaft, the power transmission device transmitting rotational force of the input shaft to the propeller shaft;
- an electric power generating equipment interposed between the internal combustion engine and the power transmission device;
- and
- an auxiliary electric motor for driving the propeller shaft, the electric motor being driven by electric power generated from the generating equipment, wherein the electric motor has an output shaft substantially coaxially connected to the substantially vertical transmission shaft of the power transmission device.
