Abstract

This invention relates to shipbuilding, in particular to ship steering devices. The purpose of the invention is to increase the maneuverability of the vessel and reduce energy costs. To control the vessel, the rudder feather 1 is shifted to a certain angle by the steering machine 6. The engine 11 rotates the cylinder 8, which, due to frictional forces, causes the closed flexible perforated tape 13 to rotate. As a result, the feather 1 of the rudder creates a lateral force so and the movement of the tape. The vessel can be controlled without reversing the feather of the 1 rudder due to the rotation of the tape 13. 3 sludge.

Description

This invention relates to shipbuilding, in particular to steering devices of ships.

The purpose of the invention is to increase the ship's agility and reduce energy costs.

FIG. depicts a rudder mounted on the ship behind the propeller; Fig 2 - section A-A in Fig 1; in FIG 3, a variant of using the rudder's feather to control the vessel (a feather of the helm without an end washer).

The feather of the rudder 1 is fixed on the bottom of the puller 2 for the screw 3 of the vessel, the hollow baller 2 passes through the helm-port pipe 4 fixed on the vessel’s hull 5, and is kinematically connected with the steering machine 6 "At the front edge of the pen roll in the supports 7 is installed cylinder 8, and on the rear edge of the pen roll in supports 9 is installed 1 cylinder 10 ° Cylinder 8 is connected to Engine 11, which can rotate cylinder 8 through shaft 12 passing inside baller 2c, Perot 1 roll | cylinders 8 and 10 covered with a closed I flexible perforated tape 13

At the ends of cylinder 8 there are beads 14, which are capable of holding | tape 13 from axial displacements

The closed bending tape 13 can be made with various openings (round, rectangular, hexagonal, etc.).

I On both end surfaces of the coil pen or on one, for example., 15 ° end washers can be installed on |

; The ship steering dp 1 of the rudder is shifted to a certain angle (fig. 3). using the steering machine 6: At the same time, the engine 11, through the shaft 12, causes the cylinder B to rotate in the direction indicated by the arrow on the head. The rotation of the cylinder 8 due to frictional forces causes the closed flexible tape 13 to move (FIGURE 3). As a result, the feather I of the rudder creates the lateral force necessary for maneuvering the vessel, caused by both the transfer of the rudder and the movement of the tape

When reversing the pen 1 roll in the opposite direction, the direction of movement of the tape 13 should be reversed as shown in Fig 3, which is achieved by reversing the engine 11.

The control of the vessel can be performed without the feathering of the pen 1 of the rudder. This should be set in motion by the engine 13, when the rudder is not shifted 1, the movement of the belt in the direction indicated in FIG. 3 creates a controlling effect on the vessel. if the feather of the rudder 1 was shifted in the direction shown in FIG. 3. When reversing the engine 11, the control effect on the vessel changes to the opposite

In the case of perforated tape 13 and the use of end washers 15, the steering device operates in a similar manner, but with higher efficiency.
