This invention relates to shipbuilding, namely to steering gears.

The purpose of the invention is to reduce the weight and size.

FIG. 1 shows the steering device; in fig. 2 - locking assembly of a puller with a rotatable crankcase of the steering device.

The steering device comprises a rotary crankcase 3 mounted in the niche 1 of the vessel 2, in which scles 4 of the rudder 5 is installed with a tiller 7 fixed to the end of the 6 of the baller and which is kinematically connected to the actuator. Rotation of crankcase 3 relative to niche 1 is limited to the device.

There are 8 stops, with the axis of rotation 9 of the rotary crankcase perpendicular to the axis 10 of the rudder and parallel to the axis 11 of the finger 12 of the tiller 7. The steering device also includes a locking device of the rudder relative to the rotary crankcase. The output link 13 of the actuator is connected to the tiller 7 and the baller 4 by means of a two-axis hinge 14, wherein the axis

The rotation of the pivot crankcase is offset relative to the axis 9 of the puller.

The locking device of the puller 4 relative to the rotary crankcase 3 is made with a hydraulic cylinder 15, a sleeve 16 and cams 17. The piston 18 of the hydraulic cylinder 15 is rigidly connected to the sleeve 16, which is mounted for movement along the bullet 4, and the cams 17 are rigidly connected to the end of the sleeve 16 and with a rotary housing 3, respectively. The actuator includes a hydraulic cylinder 19, a slider 20 with guides 21. The output link

The executive mechanism is made with a thrust 22, while the hydraulic cylinder 19 and the guides 21 are fixedly attached to the hull of the vessel coaxially with the axis of the puller 4, and the piston 23 of the hydraulic cylinder is pivotally connected through the slider 20 with the thrust 22.

The steering device operates as follows.

At the same rudder position, the working fluid is supplied under pressure of the hydraulic cylinder 15 of the device of the stop baler relative to the rotary crankcase, with the result that the piston 18 together with the bushing 16 is switched to the left and the bushing 16 locks the baller relative to the rotary casing.

To remove the rudder 5 from the vessel hull, the working fluid from the hydraulic power source is directed to the hydraulic cylinder 19, as a result of which the piston 23 extends, acting through the output link 13, pulling 22 and a two-axis hinge

14 on the finger 12 of the tiller 7. Since the puller 4 is locked on the rotary housing, the latter begins to rotate about the axis

9. After the rudder 5 has been removed from the hull of the ship hull, the rotary crankcase 3 is locked against the hull of the ship by the locking device 8 and the baller gauge 4 is released from the locking with the slewing crankcase by moving the piston 18 with the hub 16 to the right. Thereafter, the cylinder 19 is switched to the transfer. When this piston 23 acts through

Q t gu 22 and biaxial joint 14 on the tiller 7, providing a shift of the steering wheel in one direction or another.

In order to retract the slewing casing of the steering wheel 5 into the vessel hull niche, the steering wheel is first brought to the middle position. Then work

5, the fluid is supplied to the hydraulic cylinder 15, the piston 18 with the sleeve 16 moves to the left, securing the baller 4 with the rotary housing, then the steering wheel is removed by moving the piston 23

Q in hydraulic cylinder 19.
