テナンスも容易でないという問題があつた。 Traditionally, propulsion devices for tugboats and the like have had a power transmission system in which a propeller shaft and an input shaft are connected in a Z-shape via a vertical shaft, and the propeller rotates around the vertical shaft to change the direction of the propeller 360 degrees. Z that can be
Type propulsion devices are often used. When a variable pitch propeller is used as the propeller of this Z-type propulsion device, rotational motion in the circumferential direction due to the rotating motion of the propeller and axial motion along the vertical axis due to mechanical transmission of the variable pitch propeller to the blade angle indicating device. In the past, there was a rotary motion seal device, but there was no oil seal device that combined axial motion, so the mechanical transmission mechanism to the blade angle indicating device was an oil seal. The oil supply device is provided separately from the device, and the oil supply device is also provided on the outer periphery of the propeller rotating tube (not shown) with a size larger than necessary, which poses a problem that maintenance thereof is not easy.

も容易である。 In the above, the oil supply cylinder main body 1 moves in the axial direction in relation to the movement of the variable rod connected to the propeller blade, but pressurized oil from the outside is transferred to the oil supply cylinder main body 1.
Since the oil is supplied through flexible tubes 21 and 22 that allow free movement in the axial direction, movement of the oil supply tube body 1 may impede the supply and drainage of pressure oil or cause pressure oil to leak. There's nothing to do. Also, the first pressure oil pipe 15
The threaded portion 15a is screwed into the threaded portion 10b of the inner cylinder 10 and is fixed with a positioning nut 16 so as to be movable and adjustable in the axial direction, and the second pressure oil pipe 20 is

Even if the positioning nut 16 is loosened and the oil supply device A
The above problem can be prevented by finely adjusting the mounting position of the The pressure oil pipes 15 and 20, which communicate with the hydraulic cylinder in the propeller boss and are inserted through the through hole 18 of the vertical shaft 17, are provided so as to be freely rotatable in the circumferential direction with respect to the oil supply cylinder body 1. The oil pipes 15 and 20 are connected to an inner cylinder 10 that is rotatably provided in the circumferential direction with respect to the oil supply cylinder main body 1, and between the inner cylinder 10 and the oil supply cylinder main body 1, there is a pressure of the oil supply cylinder main body 1. The respective annular chambers 5 provided on the inner periphery of the oil supply cylinder body 1 that communicate the oil passages 6 and 7 with the oil holes 8 and 9 of the inner cylinder 10 are prevented from leaking to each annular chamber 5 and the outside by the rotor seal 3. Since the pressure oil pipe 15, the pressure oil pipe 15,
No pressure oil leaks from the pressure oil passages up to 20. Furthermore, since the blade angle indicating device 19 is combined with the refueling device and its main parts can be located above the Z-type propulsion device, maintenance is easy.
