Definitions

• the present invention is directed to a ship running apparatus.
• An object of the present invention is to provide a marine vessel propulsion device which has a relatively simple structure and recovers most of the eddy current energy and can use it for propulsion.
• the propulsion device for a marine vessel has an auxiliary propeller rotatably provided concentrically with the main shaft behind the main port propeller driven by the main shaft, and a space inside the auxiliary propeller.
• a planetary gear device is provided in the main shaft, and the rotation of the auxiliary propeller that is rotated is transmitted to the main shaft.
• FIGS. 1 and 2 show an embodiment of the apparatus of the present invention.
• FIG. 1 is a longitudinal sectional view
• FIG. 2 is a sectional view taken along the line II-II in FIG. 1, and
• ⁇ is the main propeller that is D-driven by the main shaft 2.
• 3 is an auxiliary propeller having wings 31 extending radially from a space 4 with a U-shaped cross section.
• Reference numeral 5 denotes a star gear device provided in the above-mentioned space 4
• a sun gear 6 is formed on an extension of the main shaft 2
• a planetary gear 7 is provided in a flank portion 4 a of the above-mentioned space 4.
• the outer metal fitting S which is rotatably mounted and has internal teeth, is fixed to the extension i (?) From the hull.
• the auxiliary propeller 3 has a pace 4 whose bearing 4 is mounted on the outer metal fitting S.
• the bearing 12 is rotatably supported via a shaft ⁇ ⁇ ⁇ , and a bearing 12 is interposed between the flange 4 a and the step of the main shaft 2.
• the auxiliary propeller 3 is provided Rotation speed of propeller 2]) At low rotation speed, concentrically turns with the main 7 ° port propeller in the same direction.
• the rotational force is transmitted to the main shaft 2 and a single sun gear 6 via the planetary gear set S, and serves to assist the power for rotating the main: 7 ° port, that is, the output of the main engine. Also F, that by the thrust and propulsion of good ship to press the main shaft 2 via the auxiliary pro Pera of pace 4-force et bearings J 2
• the rotation speed of the auxiliary propeller 3 does not become smaller than the rotation speed of the main propeller ⁇ (1 ⁇ 2, 1 ⁇ 2 below and 3 ⁇ 4 *). Go to The apparent water flow flowing into the auxiliary propeller 3 ⁇ 43 »is parallel to the centerline of the hull, and the force is directed backwards on the wing 3». Energy recovery efficiency is slightly reduced.
• the marine propulsion device of the present invention can recover most of the energy of the vortex generated behind the main pi-peller and use it for propulsion *
