（１８）により該潤滑油の漏洩が防がれている。Oil is injected into the square-shaped space (8) sandwiched between the bearings (4) and (5) to lubricate the core bearings (4) and (5). This oil is generally maintained at a pressure slightly higher than the seawater pressure corresponding to the ship's stagnation, and is kept in the stern pipe (
2) Leakage to the outside is prevented. An inner shaft (inner propeller shaft, 11) is supported inside the outer shaft (3) via bearings (12) and (13), and an intermediate shaft (1) is connected to the front end of the inner shaft (inner propeller shaft, 11).
4) causes the inner propeller (15) fixed to the rear end to rotate in the opposite direction to the outer propeller (7). In the space (16) between the bearings (12) and (13),
A sealing device (17) provided on the outside of the bearing (12) (+3) is injected with lubricating oil having approximately the same pressure as the outside lubricating oil.
(18) prevents the lubricating oil from leaking.

い。In the above stern tube device, the outer shaft (3) and the inner shaft (11
) are two bearings (4) (5012) (13) respectively.
It rotates while being supported by bearings (4), (5), and (12).
) (13) are propellers (7) (15) and shafts (3).
) (11), the load is quite high, especially the bearing (12) for the inner shaft (11) placed inside.
(13) has an even higher load because the bearing (12) (1, 3) and the shaft (11) are reversed with respect to each other. For this reason, it is essential to supply lubricating oil to the bearings (12) and (13), but this oil supply means is not established in the above-mentioned apparatus.
