<p>PURPOSE:To feed a lubricating oil smoothly to the bearing of an inside propeller shaft or a sealing device by providing one or plural lubricating oil distributing cases on the outer periphery of an outer shaft, and feeding a lubricating oil to said inside bearing and sealing device via the oil chamber of said distributing case connected to piping and a connecting port provided on said outer shaft. CONSTITUTION:A lubricating oil from a piping 21a is fed to the bearing of an inside propeller shaft through the oil feeding chamber 36 of a distributing case 22 and oil feeding port 23, and discharged from a piping 21n through an oil discharge port 24 and the oil discharge chamber 37 of the distribution case 22. Although the positions in the circumferential direction of the oil feeding port 23 and the oil discharge port 24 are varied due to the rotation of an outside propeller shaft 3, connection will not be cut off due to the oil feeding chamber 36 and the oil discharging chamber 37 which are formed in annular shapes. Thereby, the lubricating oil can be fed from a feeding piping which is fixedly provided in a hull to the inside of the outside propeller shaft 3 through the shaft 3 being rotated, enabling the bearing of the inside propeller shaft and a sealing device always to be fed with a proper quantity of lubricating oil, to improve their operating property and durability.</p> |
