구동수단의 회전축과 프로펠러의 체결구조{Connecting structure for pivot on driving means and propeller}[0001] The present invention relates to a connecting structure for a rotating shaft of a driving means and a propeller,

본 발명은 전동기나 발전기와 같은 구동수단, 또는 이러한 구동수단으로부터 연동되어 회전되는 회전축에 고정되는 프로펠러의 체결구조에 관한 것으로, 더욱 상세하게는 결합 및 해제가 간단하여 교체 또는 유지 보수가 매우 편리하도록 한 구동수단의 회전축과 프로펠러의 체결구조에 관한 것이다.
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fastening structure of a propeller fixed to a driving means such as an electric motor or a generator or a rotary shaft rotated in conjunction with the driving means, The present invention relates to a fastening structure of a rotating shaft of a driving means and a propeller.

주지한 바와 같은 발전기나 전동기와 같은 회전구동수단의 회전축과 프로펠러를 체결하는 방식에는 여러 가지 형태가 있다. There are various ways of fastening a propeller to a rotary shaft of a rotary drive means such as a generator or an electric motor as is well known in the art.

일반적으로 가장 많이 체결하는 방식을 도 1을 참조하여 설명한다.The most common method of fastening will be described with reference to Fig.

발전기 또는 전동기와 같은 구동수단(10)은 본체(11)와, 회전축(12)을 포함한다. The driving means 10 such as a generator or an electric motor includes a main body 11 and a rotary shaft 12.

또한 상기 회전축(12)에 결합 고정되는 프로펠러부(20)는 몸체(21)와 상기 몸체(21)에 부착되는 다수개의 회전날개(22)로 구성된다.The propeller unit 20 is fixed to the rotary shaft 12 and includes a body 21 and a plurality of rotary blades 22 attached to the body 21.

또한 상기 구동수단(10)의 회전축(12)에는 고정키(13)가 더 형성되고 선단부는 테이퍼 처리하여 테이퍼부(12a)를 가지도록 구성된다.The rotary shaft 12 of the driving means 10 is further provided with a fixed key 13 and a tip portion thereof is tapered to have a tapered portion 12a.

또한 상기 프로펠러부(20)의 몸체(21)에는 축공(21a)과, 키홈(21b)이 형성되어 있다.In addition, a shaft hole 21a and a key groove 21b are formed in the body 21 of the propeller part 20.

따라서 이와 같이 구성되는 구동수단의 회전축(11)에 프로펠러부(20)를 결합 고정하기 위해서는, 상기 구동수단의 회전축(11)에 프로펠러부의 축공(21a)과 키홈(21b)을 맞추어 삽입한 후, 망치 등의 공구를 통해 상기 프로펠러부(20)를 억지끼움 시켜 상기 프로펠러부(20)의 몸체(21)가 회전축(11)의 테이퍼부(21b)에 삽입되면서 단단하게 고정되는 것이다.In order to fix the propeller part 20 to the rotary shaft 11 of the driving means constructed as described above, the shaft hole 21a and the key groove 21b of the propeller part are fitted into the rotary shaft 11 of the driving unit, The body 21 of the propeller part 20 is firmly fixed while being inserted into the tapered part 21b of the rotary shaft 11 by forcibly inserting the propeller part 20 through a tool such as a hammer.

그러나 이와 같은 종래의 체결방식은 회전축(11)에 프로펠러부(20)가 삽입 고정되면 다시 분리하는 것이 쉽지 않았기 때문에 프로펠러의 교체시나 유지 보수가 어려운 문제점이 있었다.
However, in the conventional fastening method, when the propeller part 20 is inserted into the rotary shaft 11, it is difficult to remove the propeller part 20 again. Therefore, it is difficult to replace or repair the propeller.
