Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bearing assembly for a helm,

The present invention relates to a steering apparatus used in a ship, and more particularly, to a steering apparatus for a ship, which can reduce the overall manufacturing cost by changing the structure of a bush, To a bearing assembly of a steering apparatus.

Generally, a steering apparatus used for a ship is a device for changing the course of a ship by controlling the direction or angle of a rudder disposed at the bottom rear portion of the ship.

There are various kinds of such helmets, but most of the helmets used in ships are powered by hydraulic.

In addition, the above-described helm can be roughly divided into Ram type and Rotary Vane type of a ram cylinder type.

Here, the ram-type steering apparatus includes two or four hydraulic cylinders in which a ram piston is inserted, and a tiller connected to the ram and the rudder is connected to a ram pin or a lap- (Rapson Slide Shoe).

Accordingly, when the hydraulic fluid is supplied to the hydraulic cylinder and the ram is linearly reciprocated in the horizontal direction, the ramp pin and the bush (or bearing) mounted on the ram transmit the linear movement force of the ram to the tiller, As the tiller is rotated by the movement, the rudder stock provided on the tiller is rotated to adjust the direction of the rudder.

Regarding such ram type steering apparatus, it is as disclosed in the registered patent 10-0859333, the patent 10-2014-0041872, the registered patent 10-1334523, and the registered patent 10-1126959.

Meanwhile, the bush used to transmit the linear movement force of the ram to the tiller is required to be smoothly rotated and tilted with the tiller. In addition, the material of the bush is normally made of high-strength brass .

However, in the case of the high-strength brass described above, it is most preferable to use the bush (or bearing) of the above-described steering apparatus because it provides superior corrosion resistance and high strength characteristics. However, since the material itself is expensive, It is inconvenient to replace the entire bush or to grind the wall surface of the fork portion of the tiller when the deformation occurs.

In addition, since the above-described conventional bushing maintains the state inside the fork portion of the tiller, there is a disadvantage that the tiller also has to be disassembled as a whole in order to replace the bush.

The present invention has been made in order to solve various problems of the prior art described above, and it is an object of the present invention to reduce the manufacturing cost as a whole and to make replacement work easy and easy, The present invention provides a bearing assembly for a helm of a ship according to a new form that enables reduction of the cost of the helm.

In order to achieve the above object, a bearing assembly of a steering apparatus for a marine vessel of the present invention includes a bearing assembly that is positioned inside a fork portion of a tiller and transmits a horizontal movement force transmitted through a ramp pin to the tiller to rotate the tiller A steering apparatus for a marine vessel, the bearing assembly comprising a body formed of a steel body and having a press-in hole formed vertically at the center thereof; A cylindrical sub body which is press-fitted and fixed in the press-in hole of the body part and which supports the rotation of the ram pin with the ramp pin inserted therethrough; And a contact pad portion formed of a high-strength brass material and fixed to the circumferential surface of the body portion, the outer surface of the contact pad portion contacting the inner wall surface of the fork portion.

The body portion is formed as a square block, and the contact pad portion is formed as a flat pad fixedly installed on a surface of the body portion facing the inner wall surface of the fork portion of the circumferential surface of the body portion.

In addition, at least one injection hole for injecting lubricant up to the inner surface of the sub body may be formed on the circumferential surfaces of the body part, the contact pad part, and the sub body.

In addition, the upper surface of the body part may further include a ring part for separating the bearing assembly from the ramp pin.

As described above, the bearing assembly of the present invention is not formed entirely of a high-strength brass material but only a part of the bearing assembly is made of a high-strength brass material, thereby reducing the overall manufacturing cost. Further, The maintenance cost can be reduced by replacing the spare parts.

Particularly, the bearing assembly of the helm of a ship according to the present invention does not disassemble the entire tiller of the contact pad portion of the bearing assembly, but only the bearing assembly is separated from the fork portion of the ramp and tiller, It is possible to achieve the effect.

FIG. 5 is a perspective view illustrating a bearing assembly of a marine steering apparatus according to a preferred embodiment of the present invention 6 is a side view illustrating a bearing assembly of a marine steering apparatus according to a preferred embodiment of the present invention, and FIG. 7 is a perspective view illustrating a bearing assembly of a marine steering apparatus according to a preferred embodiment of the present invention Fig.

As shown in these drawings, the bearing assembly 100 according to an embodiment of the present invention includes a main body 110, a main body 120, and a contact pad unit 130, The body part 100 is formed of a common steel material and the contact pad part 130 is formed of a high-strength brass material. The body part 120 is press-fitted into the body part 110, do.

This will be described in more detail below for each configuration.

First, the body 110 forms a basic body of the bearing assembly 100.

In the embodiment of the present invention, the body part 110 is formed of a square block of steel material, thereby making it possible to reduce the manufacturing cost and to manufacture the body part 110 easily.

In addition, a press-in hole 111 penetrating vertically through the body 110 is formed at the center of the body 110. The press-in hole 111 is a portion for pressing and fixing the sub-body 120, which will be described later, and is formed as a circular hole.

In addition, the body 110 according to the embodiment of the present invention is further provided with an annular portion 112 on the upper surface thereof.

The ring part 112 is a ring part used for connection of a lead wire or the like when the entire bearing assembly 100 is to be separated from the ramp pin 20 and is formed as a normal eye bolt. At this time, it is preferable that the annular portions 112 are positioned at two positions, which are diagonal to each other, on the upper surface of the body 110 as viewed in plan, as shown in the embodiment.

Next, the sub body 120 is a portion for supporting the rotation of the ramp pin 20.

The sub body 120 is press-fitted into the press-in hole 111 of the body 110, and is installed so as to penetrate the inner side of the sub body 120.

The bent end 121 is formed at the lower end of the sub body 120 so that the sub body 120 is inserted into the press-in hole 111 of the body part 110, To prevent excessive press-fitting in the press-fitting process.

In addition, since the inner circumferential surface of the lower end of the sub body 120 gradually increases in diameter toward the bottom, the coupling operation of the ramp pin 20 can be accurately and easily performed.

The auxiliary body 120 and the body 110 may be fastened and fixed using a plurality of connection bolts 122 so that the auxiliary body 120 extends from the inner circumferential surface of the insertion hole 111 of the body 110 To prevent unwanted rotation. At this time, the connection bolts 122 are coupled to the upper surface between the sub-body 120 and the body 110.

Next, the contact pad portion 130 is a portion contacting the inner circumferential surface of the fork portion 11 constituting the tilter 10.

The contact pad portion 130 is formed of a high-strength brass material. In this case, the high-strength brass material is made of a copper-zinc alloy to which Ni, Al, Sn, Si, Mn, Fe and the like are added and has a high tensile strength.

In other words, in the conventional case, the entire bearing assembly 100 is formed of a high-strength brass material. However, in the embodiment of the present invention, only the contact pad portion 130, which is in direct contact with the fork portion 11 of the tiller 10, And the body 110 is formed of a normal steel material so that the overall manufacturing cost can be reduced.

In addition, the contact pad unit 130 is formed of a flat pad fixed to the outer circumferential surface of the body 110 and having an outer surface contacting the inner wall surface of the fork unit 11.

Particularly, the contact pad portion 130 and the body portion 110 are fastened by using a plurality of fastening bolts 131, thereby enabling stable connection between the contact pad portion 130 and the body portion 110, So that the contact pad unit 130 can be easily separated from the body 110 according to need.

A lubricant is applied to the inner surface of the sub body 120 (a portion between the sub body and the ramp pin) on the circumferential surfaces of the body part 110, the contact pad part 130 and the sub body 120, At least one injection hole 140 is formed to penetrate through at least one injection hole.

That is, through the additional formation of the injection hole 140, the abrasion due to the friction between the sub body 120 and the ramp pin 20 can be minimized between the contact surfaces of the sub body 120.

Of course, the lubricant injected through the injection hole 140 may be provided on the inner circumferential surface of the sub body 120 such that the lubricant injected through the injection hole 140 may be uniformly distributed over the entire area between the inner peripheral surface of the sub body 120 and the ramp pin 20 It is more preferable to form the guide grooves 123 for the guide grooves.

In the following, the operation of the bearing assembly 100 according to the embodiment of the present invention described above will be described in more detail.

First, the initial state in which the operation control for steering is not performed is as shown in FIGS. 1 to 3 attached hereto.

That is, since the high-pressure fluid is not supplied to the hydraulic cylinders 41 and 42, the ram 30 is maintained in the center position, so that the tiller assembly 10 is not rotated to the left or right, While the rudder (not shown) is maintained in the same direction as the traveling direction of the ship.

In this initial state, if the operation control in the wheelhouse is performed to steer the ship, the high-pressure fluid is supplied to one of the two hydraulic cylinders 41 and 42, The linear movement of the ram 30 and the rotation of the tiller 10 are performed.

For example, when the high-pressure fluid is supplied to the front right hydraulic cylinder 41 in the drawing, the ram 30 is linearly moved to the left, and the tiller assembly 10 is also rotated to the left (clockwise in the drawing) When the high-pressure fluid is supplied to the hydraulic cylinder 42, the ram 30 is linearly moved to the right and the tiller assembly 10 is also rotated to the right (counterclockwise in the drawing).

As a result, the rudder is also rotated to the left or right so that the ship is steered.

When the bearing assembly 100 is worn due to the operation of the marine steering apparatus described above, the bearing assembly 100 is fixed to the fork of the ramp pin 20 and the tiller 10 by using the ring 112. [ (11).

Thereafter, the fastening bolts 131 fastened between the contact pad part 130 and the body part 110 are disengaged to replace the new contact pad part 130.

As a result, the entire bearing assembly 100 of the present invention is not formed of a high-strength brass material but only a part of the bearing assembly 100 (for example, a contact pad portion) is made of a high-strength brass material, When the contact pad unit 130 is worn, only the corresponding contact pad unit 130 is replaced, thereby reducing the maintenance cost.

Particularly, it is not necessary to disassemble the entirety of the tilter 10 for the contact pad portion 130 of the bearing assembly 100, but only the corresponding bearing assembly 100 can be used for the fork portion 11 of the rampin 20 and tilter 10 The replacement operation can be performed easily and quickly.

Meanwhile, the bearing assembly 100 according to the present invention is not limited to the structure having a rectangular block shape as in the above-described embodiment, but may be applied to various structures such as a cylindrical shape and other polygonal blocks. It can be said.
