The present invention relates to a rudder stock of a rudder for ships having a reinforcement function against a bending moment, and in detail, a response force to a bending moment generated and transmitted from the rudder during a ship operation may be improved in a state in which the structure of the rudder stock is not changed. I would have to.

The rudder, which determines the direction of operation during operation of the ship, is installed in front of the propellers (other devices for generating other propulsion, etc.) for providing propulsion from the rear end of the hull.

When the rudder is generated by the propeller, such a rudder is rotated about a vertical axis in the forward direction of the propulsion flow to perform a steering function when the ship proceeds.

1 is an exemplary view showing the configuration of the rudder described above.

Referring to the drawings, the rudder rudder rudder (1) is fitted to the bearing (3) installed on the rear end lower side of the hull, the rudder panel (2) to guide the water flow to one side of the lower end of the rudder stock (1) ) Is combined.

Naturally, the steering device is configured to connect the rudder stock to the upper part of the rudder stock 1 so as to angularly rotate the rudder stock 1 with respect to the longitudinal axis, and the steering device performs a steering wheel function of the ship cab. The connection to the key and the like is well known.

Since the rudder stock 1 of the rudder as described above is configured in the form of a cantilever beam having one end supported with respect to the rudder 2, when a propulsion flow is generated by a propeller or the like, the lower side of the rudder stock 1 supports the rudder stock 1. At the point of bearing 3 a bending moment is generated.

This bending moment causes a twist of the rudderstock 1, which causes the driver not to steer in the desired direction during the operation of the ship.

In order to prevent the above factors, it is proposed to change the structure of the rudder stock to expand the diameter in order to increase the response to the bending moment, it is proposed to change the structure of the rudder stock is the point where the rudder stock is mounted and its peripheral parts This leads to the disadvantage of having to carry out a lot of process changes in accordance with the change of the standard.

In addition, as the diameter of the rudder stock is enlarged, the material cost of the enlarged diameter is wasted, and the weight of the rudder stock that provides the weight of the rudder is increased, resulting in a waste of power caused by rotating the rudder stock. .

The present invention was devised to solve the above-mentioned problems, and the rudder stock of the rudder for ships was made to increase the responsiveness to the bending moment by adding a simple configuration to the outside without changing the structure of the already standardized rudder stock. The purpose is to provide.

In order to achieve the above object, the present invention has the following configuration.

The present invention, in the rudder for steering the ship by inducing a propulsion flow generated by the propeller, such as propellers are coupled to the rudder stock rotatably mounted on the lower side of the hull rear end of the ship, the rudder panel is coupled to the bottom of the rudder stock. ,

The outer surface of the rudder stock is installed so that one end of the reinforcing member is interfering between the points in contact with the hull, and the other end of the reinforcing member is coupled to the rudder panel.

Hereinafter, with reference to the accompanying drawings an embodiment of the present invention to which the configuration is applied will be described in detail.

2 is a front view of the rudder stock according to the present invention, Figure 3 is a rudder stock side view of FIG.

Referring to the drawings, the rudder stock 10 according to the present invention is rotatably coupled to the hull (S), the rudder panel 20 is coupled to the lower end to substantially induce water flow, rudderstock 10 Includes a reinforcing member 30 interposed between the rudder panel 20 and the hull S.

Here, the reinforcing member 30 is fitted to the outside of the rudder stock 10 is fixedly coupled, the upper end is coupled to interfere between the hull (S) and the rudder stock 10 is the rudder stock 10 and the hull (S) Reinforces the point of attachment.

That is, the reinforcement member 30 prevents the bending load from being directly transmitted to the rudder stock 10 with respect to the bending moment generated when the rudder panel 20 induces propulsion of the propeller such as a propeller. Naturally configured to be rotatable with the rudderstock 10 in the state fitted in S).

Therefore, the reinforcement member 30 performs the role of the bearing between the hull S and the rudder stock 10. In fact, as the rudder stock 10 is rotated at a low speed, it is applied as a bearing metal of the sliding bearing. .

In addition, the lower end of the reinforcing member 30 is configured to be combined with the rudder panel 20, this coupling state is the lower end of the reinforcing member 30 is extended to the inside of the rudder panel 20, the extended point and the rudder The whole side part 31 of the reinforcing member 30 which the panel 20 contacts is comprised so that it may be a coupling point.

This is configured to allow the bending moment acting as a load on the upper end of the reinforcing member 30 to be applied to the rudder panel 20 rather than the rudder stock 10 so that the bending moment can be dissipated in the entire rudder.

Coupling point edge portion 31 and the rudder panel 20 of the reinforcing member 30 is provided with a bonding force mainly by joining by welding, etc., in order to exclude such a coupling work process, the rudder panel 20 and the reinforcing member ( It may also be desirable to configure 30) integrally.

In summary, the configuration of the rudder stock 10 is a reinforcing member 30 to perform a bearing metal of a sliding bearing as a hollow tube to which the rudder stock 10 can be fitted. 30 is a configuration that maintains a rigid coupling state with the rudder panel 20.

Figure 4 is an illustration of the state of use of the rudder stock according to the present invention.

Referring to the drawings, the rudder stock 10 including the reinforcing member 30 is installed in the lower rear side of the hull (S) as is well known, the hull (S) is coupled to the rudder stock 10 to be rotated An installation configuration is prepared for this purpose.

The installation configuration, the housing 41 coupled to the hull (S), the support portion 42 for rotatably supporting the rudder stock 10 in the interior of the housing 41, the rudder stock is connected to It consists of a steering mechanism part 43 for rotating 10).

The housing 41 has a lower end thereof fitted to the upper outer circumferential surface of the reinforcing member 30 described above, and an upper end portion of the housing 44 on the outer circumferential surface of the upper portion of the rudder stock 10, the bush 44, the sleeve 45, and the sealing member 46. The support part 42 of the interposed is coupled.

The steering mechanism 43 has a cam 47 coupled to the upper end of the rudder stock 10, and the driving rods 48 are coupled to both sides of the cam 47, respectively.

In this configuration, when the driver manipulates a key or the like and the driving rod 48 is moved in the direction of the arrow in the drawing, the cam 47 is rotated at an angle to rotate the rudder stock 10 and the rudder stock 10. By the rotation of the reinforcement member 30 and the rudder panel 20 is to perform the steering of the ship.

As described above, the present invention can improve the responsiveness to the bending moment by the addition of a simple configuration through a reinforcing member on its outer surface without changing the structure of the already standardized rudder stock.

Therefore, the present invention has the effect of simplifying the process by adding a simple configuration without excessive design change and reducing the material cost for manufacturing the rudderstock, compared to the bending moment corresponding configuration of the rudderstock having an expanded diameter.

In addition, the present invention obtains the effect of reducing the power when driving the rudderstock as the weight of the rudderstock itself is reduced.
