An annular cover that houses the rotor 3 inside, inserts the lower shaft portion 3a of the rotor 3 into the boss portion 2a provided on the inner bottom portion of the housing 2, and arranges the upper shaft portion 3b in the upper opening of the housing 2. The lower shaft portion 3a is rotatably held by the radial bearing member 5a and the thrust bearing member 5b, and the upper shaft portion 3b is rotatably held by the radial bearing member 5c. As a result, the rotor 3 becomes rotatable with a load applied in the radial direction and the axial direction.

The housing 2 is provided with an annular mounting flange 2b on the lower portion of the outer peripheral surface thereof so as to project in the radial direction, and is attached to the steering machine mounting base 16 via the mounting flange 2b. The rotor 3 is provided with vanes 6 projecting radially on the outer circumferential surface at equal intervals along the circumferential direction, and the housing 2 is provided with the vanes on the inner circumferential surface at equal intervals along the circumferential direction. The same number of segments 7 are provided so as to project in the radial direction, and a sealing material 8 is provided at each edge of the vanes 6 and the segments 7. With this configuration, an oil-tight oil chamber 9 is formed between each vane 6 and each segment 7, and the rotor 3 rotates inside the housing 2 by feeding oil to each oil chamber 9 with a hydraulic pump.

The rotor 3 has an internal through hole 3c at its center, and the top end portion 10a of the rudderstock 10 is inserted into this internal through hole.
Fit and fix. Since the penetrating portion 11a of the rudder shaft 10 on the steering gear deck 11 is below the waterline of the ship, this penetrating portion 1
The water sealing device 12 for keeping the watertightness of 1a is attached to the steering gear deck 11
It is attached directly to. Further, as shown in FIG. 12, a neck boss 15 including a neck bearing 14 that supports a radial load of the rudder shaft 10 is attached to the rudder shaft penetrating portion 13a of the stern hull 13.

It is mounted on the peripheral edge of the center hole formed on the mounting base plate and assembled into a united body with a deck seal material that slides in watertight contact with the rudderstock. It has a rotor, a housing for accommodating the rotor to form an oil chamber space around the rotor, and an annular cover arranged in the upper opening of the housing, and has an equal interval along the circumferential direction of the outer peripheral surface of the rotor. Arranging a plurality of vanes at a position, arranging a plurality of segments at positions at equal intervals along the circumferential direction of the inner peripheral surface of the housing, partitioning the oil chamber space into a plurality of oil chambers by vanes and segments, The lower shaft portion of the rotor is rotatably supported by the boss portion of the inner bottom portion of the housing through the radial bearing member and the thrust bearing member capable of supporting the axial total load applied to the rudder shaft, and the upper shaft portion of the rotor. The radial bearing part It is rotatably supported by an annular cover through the material, and a mounting flange is projected from the lower part of the outer peripheral surface of the housing.The steering gear mounting base is joined to the steering gear mounting flange, The installation base plate has a central hole for inserting the mounting plate, and a downwardly extending support plate joined to the bottom surface of the installation plate.The mounting base plate is joined to the lower end of the support plate and has a peripheral edge at the upper peripheral edge. 3 or more stay members protruding outward from the stay member are provided at substantially equal intervals, screw holes are vertically penetrated through protruding end portions of the stay member, and adjusting bolts are screwed into the screw holes, or the mounting base plate 3 or more screw holes are vertically penetrated in the peripheral edge of the steering wheel at almost equal intervals, and adjustment bolts are screwed into the screw holes. Weld to the periphery of the fitting hole or attach the base plate. Rotary vane type steering gear, characterized in that welding the peripheral lower edge to the steering armored plate. 8. A steering gear to which a rudder shaft is attached, a steering gear installation base which supports the steering gear and is arranged under the steering gear, and a steering gear which is arranged under the steering gear installation base. A mounting base plate that is loosely fitted in a fitting hole of a predetermined diameter formed on the machine deck or is placed on the peripheral deck of a mounting hole of a predetermined diameter formed on the steering machine deck,
A deck seal material that is attached to the peripheral edge of the center hole formed in the mounting base plate and is in watertight sliding contact with the rudder shaft, a cylindrical trunk that is concentrically arranged on the lower surface of the mounting base plate, and a neck that is joined to the lower end of the trunk. A neck boss with a bearing inside is assembled into a united body.The steering machine is a housing that fits and mounts on the rudder shaft and a housing that houses the rotor and forms an oil chamber space around the rotor. And an annular cover arranged in the upper opening of the housing, and a plurality of vanes are arranged at positions at equal intervals along the circumferential direction of the outer peripheral surface of the rotor, and along the circumferential direction of the inner peripheral surface of the housing. A plurality of segments are arranged at equidistant positions, the oil chamber space is divided into a plurality of oil chambers by the vanes and the segments, and the lower shaft part of the rotor is applied to the radial bearing member and the rudder shaft in the axial total load. Is rotatably supported by the boss portion of the inner bottom portion of the housing via a thrust bearing member that can support, and the upper shaft portion of the rotor is rotatably supported by an annular cover through the radial bearing member. A mounting flange is provided on the lower part of the outer peripheral surface of the housing, and the steering mount is joined to the steering flange of the steering unit and has a center hole for inserting the rudder shaft, and the bottom of the mounting plate. The mounting base plate is joined to the lower end of the support plate and has three or more stay members projecting outward from the peripheral edge at the peripheral edge of the upper surface at substantially equal intervals. It is provided by mounting a screw hole vertically on the projecting end of the stay member and screwing an adjusting bolt into the screw hole, or at least three screw holes at the peripheral edge of the mounting base plate at approximately equal intervals.
