The present invention relates to a steering apparatus for a ship having a bearing assembly that is disposed 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 body portion formed by vertically inserting a press-in hole vertically in the center; 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 a circumferential surface of the body portion and having an outer surface contacting the inner wall surface of the fork portion. Thereby reducing overall manufacturing costs and reducing maintenance costs.
Description
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.
