본 발명은 선박에 사용되는 프로펠라의 제작방법에 있어서 종래와 같은 주조법이나 삭성법의 개념에서 완전 벗어나 프로펠라 날개의 평면 형상의 철심에 프로펠라의 높낮이에 맞추어 수개의 핀을 꽂아 프레임을 형성한 후 그 외부에 세라믹 등의 복합재료를 융착하고 이를 프로펠라의 형태로 가공한 선박용 철심 프로펠라와 그 제작 방법에 관한 것이다.The present invention in the method of manufacturing a propeller used for ships completely out of the concept of the casting or shaping method as in the prior art by inserting a few pins in accordance with the height of the propeller to the flat core of the propeller wing to form a frame after the outside The present invention relates to a ship core propeller, in which a composite material, such as ceramic, is fused and processed into a propeller, and a manufacturing method thereof.

으로 완료되는데 삭성법의 장점은 정밀도에 있고, 정확한 치수를 요하는 프로펠러의 제작에서 주로 사용되고 있는 이 방법은 대체적으로 공정이 길고 복잡하며 대량 생산을 할 수 없는 결점을 가지고 있다.The advantage of the forming method is precision, and this method, which is mainly used in the production of propellers requiring accurate dimensions, has a long process, a complex process, and a large volume production defect.

그러나 주조법은 대량 생산에는 잇점이 있지만 주조기술에 따라서 정확한 치수를 만들기 어렵고 또한 마무리 작업 공정을 거쳐야 되므로 공정이 길어지는 결점을 갖고 있는 것이다. 그러나 본 발명에서 제시하는 방법은 위의 결점을 모두 보완하기 위해서 세라믹, 엔지니어링 플라스틱 등의 복합재료를 이용하여 정확한 치수를 가지면서 제작 기간이 짧고 대량생산에도 유리한 방법으로 프로펠라를 제조하는 것이다.However, the casting method is advantageous in mass production, but it is difficult to make accurate dimensions according to the casting technology and also has to be finished, so the process is lengthy. However, the method proposed in the present invention is to produce a propeller in a method that is short in the manufacturing period and advantageous to mass production using a composite material such as ceramics, engineering plastics, etc. to compensate for all the above drawbacks.

이하 발명의 요지를 첨부도면에 연계하여 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

우선 제2도와 같이 프로펠러 날개의 대체적인 외형을 갖춘 철판(1)을 제작하고, 그 철판(1)에 각 날개의 치수에 맞게 핀(2) (2')를 부착한다.First, as shown in FIG. 2, a steel plate 1 having an external shape of a propeller blade is manufactured, and pins 2 and 2 'are attached to the steel plate 1 according to the dimensions of each blade.

이때 이핀(2) (2')은 프로펠러의 도면 off-set에서 제시되어 있는 치수를 그대로 유지해야 한다.The pins (2) (2 ') should maintain the dimensions shown in the off-set of the propeller.

그리고 난 뒤, 프로펠러 날개를 완전히 감쌀 수 있게 제3도와 같이 세라믹 등의 복합재료 C를 붙이면 결국 처음 만든 철판(1)은 프로펠러 날개의 철심 형태로 된다.Then, when the composite material C, such as ceramics, is attached as shown in Fig. 3 so as to completely wrap the propeller blades, the first iron plate 1 is finally formed in the form of an iron core of the propeller blades.

이때 복합재료는 세라믹 등으로 하여 응고되기 전에 치수를 유지하는 핀(2) (2')만큼에 맞도록 표면을 가공하여 응고시키면 프로펠러(3)의 날개가 완성되는데, 이때 날개의 루트(4)부분은 프로펠러의 허브(5)와 조립해서 제작할 수 있도록 철판(1)의 끝단에 미리 만들어 놓으면, 각각의 날개를 따로 따로 제작하여 최종적으로 날개와 허브 부분을 조립하면 프로펠러가 완성되는 것이다.At this time, the composite material is made of ceramic or the like, and the surface of the propeller 3 is solidified by processing the surface to fit as much as the pins 2 and 2 ', which maintain the dimensions before solidification. If the part is made in advance at the end of the iron plate (1) to be manufactured by assembling with the propeller hub (5), each wing is made separately to finally assemble the wing and the hub portion is to complete the propeller.

그러므로 본 발명은 선박용 프로펠러의 제작방법중 삭성법과 구조법의 단점은 배제하고 장점만 취함으로서 정밀하고 쉽고 저렴하게 제작할 수 있음으로서 조선업에 널리 사용할 수 있는 것이다.Therefore, the present invention can be widely used in the shipbuilding industry because it can be manufactured precisely, easily and inexpensively by taking advantage of the disadvantages of the forming method and the structural method of the ship propeller manufacturing method.
