본 고안은 각종 정·역회전용 회전축과 풀리를 연결시키는데 사용하는 회전축 고정장치에 관한 것으로서, 특히 종래처럼 볼트와 너트방식 또는 핀이나 링 등을 이용하지 않고, 지지편과 걸림편 및 탄성편으로 이루어지는 클립을 이용하여 손쉽고 간편하게 회전축을 고정할 수 있도록 한 회전축 고정장치에 관한 것이다.The present invention relates to a rotating shaft fixing device used to connect the rotating shaft and the pulley for various forward and reverse rotations, and in particular, made of a support piece, a locking piece and an elastic piece without using a bolt and nut method or a pin or ring as in the related art. The present invention relates to a rotating shaft fixing device which can fix the rotating shaft easily and simply using a clip.
일반적으로 각종 회전축은 풀리나 기어 등과 연결고정되어 회전축의 회전력을 풀리나 기어 등에 전달할 수 있게 된다.In general, various rotary shafts are connected to a pulley or gear, and thus, the rotational force of the rotary shaft can be transmitted to the pulley or the gear.
따라서 풀리나 기어 등과 회전축을 연결고정하는 고정수단이 필요하게 되는데 이와같은 목적으로 이용되는 종래의 회전축 고정장치를 보면 제1도에서 보는 바와같이 회전축(20)의 일단에 나사부(21)을 형성하고, 풀리나 기어 등의 회전체(22)에는 축연결공(23)을 형성하여 상기 회전축(20)을 풀리나 기어 등의 회전체(22), 축연결공(23)에 삽입한 다음 회전축(20)의 일단 나사부(21)에 너트(24)를 체결하여 회전축(20)을 회전체(22)에 연결고정 시킬 수 있게 구성되어 있다.Therefore, a fixing means for connecting and fixing the rotating shaft and the pulley or the gear is required. In the conventional rotating shaft fixing device used for this purpose, as shown in FIG. 1, the screw 21 is formed at one end of the rotating shaft 20, A shaft connecting hole 23 is formed in the rotating body 22 such as the pulley or the gear, and the rotary shaft 20 is inserted into the rotating body 22 and the shaft connecting hole 23 such as the pulley or the gear. It is configured to fasten the nut 24 to the threaded portion 21 to fix the rotating shaft 20 to the rotating body 22.
따라서 상기와 같은 종래의 회전축 고정장치는 역회전시 너트가 풀리는 현상이 나타나 회전체와 회전축의 고정을 견고하게 할 수 없고, 이에 따라 제품의 품질과 신뢰성이 저하될 뿐 아니라 너트를 체결하여야 하므로 작업성이 떨어지고 생산성이 저하되며 제조원가도 상승시키는 요인이 되었던 것이다.Therefore, the conventional rotation shaft fixing device as described above is a phenomenon that the nut is loosened during the reverse rotation, can not be firmly fixed to the rotating body and the rotating shaft, thereby reducing the quality and reliability of the product as well as tightening the nut work Its deterioration in productivity, productivity, and manufacturing costs also contributed to the increase.
본 고안은 상기와 같은 종래의 제반문제점을 보완하고져 회전축의 일단에 걸림면을 형성하고, 이에 연결고정되는 회전체의 축연결공 상부에는 걸림홈을 형성하여 회전축을 회전체의 연결공에 삽입한 후 상부의 걸림홈에 지지편과 걸림편 및 탄성편을 갖는 클립을 끼워 회전축을 회전체와 연결고정할 수 있게 하는데 그 목적이 있는 것으로서,The present invention is to complement the conventional problems as described above to form a locking surface at one end of the rotating shaft, and to form a locking groove in the upper part of the shaft connection hole of the rotating body connected to the rotating shaft inserted into the connecting hole of the rotating body After that, by inserting a clip having a support piece, a locking piece and an elastic piece in the upper locking groove, the purpose of the connecting shaft to be fixed to the rotating body,
이하 본 고안을 첨부한 도면에 의하여 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
본 고안의 구성을 보면 제2도에서 보는바와 같이 회전축(1)과 회전체(2)를 연결고정함에 있어서, 상기 회전축(1)의 일단에 단턱지게 걸림면(3)을 형성하고, 이에 연결고정되는 회전체(2)의 축연결공(4) 상부로 사다리꼴 형상의 걸림홈(5)을 형성하여 상기 회전축(1)의 걸림면(3)과 회전체(2)의 걸림홈(5)에 제3도에서 보는바와 같이 지지편(6)과 걸림편(7) 및 탄성편(8)이 일체로 형성되는 클립(9)을 끼워 회전축(1)을 고정할 수 있게 구성된 것이다.In the construction of the present invention, as shown in FIG. 2, in the fixing of the rotating shaft 1 and the rotating body 2, a locking surface 3 is formed to be stepped at one end of the rotating shaft 1, and connected thereto. A trapezoid-shaped locking groove 5 is formed on the shaft connecting hole 4 of the rotating body 2 to be fixed, so that the locking surface 3 of the rotating shaft 1 and the locking groove 5 of the rotating body 2 are formed. As shown in FIG. 3, the support shaft 6 and the locking piece 7 and the elastic piece 8 are fitted with a clip 9 integrally formed to fix the rotating shaft 1.
이상과 같이 구성되는 본 고안의 실시예에 따른 작용효과를 설명하면 다음과 같다.Referring to the effect of the embodiment of the present invention is configured as described above are as follows.
먼저 상기 회전체(2)의 축연결공(4) 상부에 형성되어 있는 사다리꼴 형상의 걸림홈(5)에 클립(9)의 지지편(6)과 걸림편(7)을 이용하여 밀어끼우게 되면 클립(9)의 지지편(6)과 걸림편(7)이 상기 회전체(2)의 걸림홈(5)에 걸려지면서 클립(9)이 고정되고 이때 클립(1)의 탄성편(8)이 축연결공(4)의 상부에 위치하게 된다.First, the trapezoidal locking groove 5 formed in the upper portion of the shaft connection hole 4 of the rotating body 2 is pushed using the support piece 6 and the locking piece 7 of the clip 9. When the support piece 6 and the locking piece 7 of the clip 9 is caught in the locking groove 5 of the rotating body 2, the clip 9 is fixed and the elastic piece 8 of the clip 1 ) Is located at the top of the shaft connection hole (4).
이 상태에서 회전축(1)의 일단 걸림면(3)이 상기 클립(9)의 탄성력을 축적하면서 회전축(1)의 걸림면(3)을 압압하여 회전축(1)이 고정되게 되는 것이다.In this state, the one end engaging surface 3 of the rotating shaft 1 accumulates the elastic force of the clip 9 and presses the engaging surface 3 of the rotating shaft 1 to fix the rotating shaft 1.
여기서 상기 회전축(1)의 고정상태를 더욱 견고하게 하려면 클립(9)의 탄성력을 증대시켜 주면 된다.In this case, to further secure the fixed state of the rotating shaft 1, the elastic force of the clip 9 may be increased.
이상에서 설명한 바와같이 본 고안은 종래처럼 너트를 조여 회전축을 회전체에 고정시키지 않고 클립을 한번에 밀어끼워 삽입하는 공정으로 회전축을 고정할 수 있으므로 고정작업이 매우 손쉽고 간편할 뿐 아니라 회전축의 역회전시에도 풀림현상이 방지되어 제품자체의 품질과 신뢰성을 향상시킬수 있고 또한 저가의 클립을 이용하여 회전축을 고정하고 작업이 간편하여 인력의 낭비를 줄이므로서 제조원가도 절감시킬 수 있는 효과를 얻고자 한 것이다.As described above, the present invention can fix the rotating shaft by inserting a clip at a time without fastening the rotating shaft to the rotating body by tightening the nut as in the prior art, so the fixing operation is very easy and simple, and the reverse rotation of the rotating shaft In order to prevent the phenomenon of loosening, it is possible to improve the quality and reliability of the product itself, and to reduce the manufacturing cost while reducing the waste of manpower by fixing the rotating shaft by using a low-cost clip and simplifying the work. .
