Abstract

PURPOSE: To simplify the construction and facilitate the assembly by means of a propeller blade mount section provided on the propeller shaft.
CONSTITUTION: A mount section 11 for a propeller blade 2 is formed integral at one end of a propeller shaft 4 connected to the main engine 10 through a coupling 7 and an intermediate shaft 8. On the circumference of the mount section 11, a plurality of propeller blades 2 are planted and fixed with a bolt 12, while a propeller cap 3 is mounted to the end of the mount section 11 with a bolt 13. In addition, the periphery of the mount section 11 is provided with a anti-corrosion metal 14 and a coating material 15. With such an arrangement, even after a ladder 1 is installed, the propeller blades can be mounted to the section 11 with ease. With the driving of the main engine, the propeller blades are rotated to propell the ship.
