Description

유·공압 실린더용 부싱Bushings for hydraulic and pneumatic cylinders

제1도는 본 고안의 분해사시도.1 is an exploded perspective view of the present invention.

제2도는 본 고안의 단면도.2 is a cross-sectional view of the present invention.

* 도면의 주요부분에 대한 부호의 설명* Explanation of symbols for main parts of the drawings

1 : 축공 2 : 부싱1: Axle 2: Bushing

3 : 패킹 4 : 홈3: packing 4: groove

5,5' : 요철부 6 : 밀착판5,5 ': uneven portion 6: contact plate

본 고안은 피스톤롯드를 축설한 유압 및 공압실린더의 선단에 축착하여 실린더를 지지하는 부싱에 있어서 기밀을 유지시키기 위해 내부에 감착하는 패킹장치의 개량에 관한 것이다.The present invention relates to an improvement of a packing device that is internally squeezed in order to maintain airtightness in a bushing for supporting a cylinder by squeezing a piston rod at the tip of a hydraulic and pneumatic cylinder.

일반적으로 부싱은 기름 또는 공기가 누설되지 않도록 부싱의 내부에 요홈을 환설하여 각각의 요홈에 패킹링을 끼워넣게되는바 이는 피스톤롯드가 강력한 압력으로 작동하면 패킹링의 저면을 통해 유체가 누설되어 실린더의 작동이 불량하고 또한 패킹이 마모되면 패킹사이의 부싱동체가 피스톤롯드와 마찰되어 마손되므로 얼마인가 실린더전체를 교체해야되는 비경제적인 폐단이 있었다.In general, the bushing inserts grooves into the grooves in order to prevent oil or air from leaking out. When the piston rod operates at a high pressure, the fluid leaks through the bottom of the packing ring and the cylinder If the operation is poor and the packing is worn out, the bushing body between the packings is rubbed with the piston rod and worn out.

본 고안은 이와같은 점을 감안하여 부싱의 축공내벽에 단일체로 형성한 한 개의 패킹으로 삽탈자재되게 감착하므로서 종래의 결점을 일소한것인데 이를 첨부도면에 의거 상술하면 다음과 같다.The present invention has been made in view of the above point by inserting a single piece formed in a single body on the inner wall of the shaft hole of the bushing to be inserted and detached to eliminate the drawbacks of the prior art.

축공(1)이 관통된 부싱(2)의 내부에 패킹(3)을 감착함에 있어서 축공(1)의 내벽에 요설한 통상의 홈(4)에 대응하는 요철부(5)(5')를 외면에 형성하고 내면에는 밀착판(6)을 내향경사지게 돌설시킨 부싱(2)과 동일형상의 패킹(3)을 삽탈자재되게 감착하여서되는 것이다.In the fitting of the packing 3 inside the bushing 2 through which the shaft hole 1 penetrates, the uneven portion 5, 5 ′ corresponding to the normal groove 4 recessed in the inner wall of the shaft hole 1 is provided. Is formed on the outer surface and the inner surface of the bushing (2) inclined inclined inwardly in close contact with the packing (3) of the same shape.

이와같이된 본 고안은 부싱(2)의 축공(1)에 부싱(2)과 동일형상으로 형성한 단일체의 패킹(3)을 삽탈자재되게 감착한 것으로 부싱(2)과 동일한 길이의 패킹(3)이 피스톤롯드와 긴밀히 밀착되므로 기밀상태가 매우 우수하여 유체가 누설되는 일이 전혀 없으며 종래와 같이 패킹(3)이 마모되어 부싱동체가 피스톤롯드와 마찰되는 폐단이 해소되므로 실린더의 수명을 연장시킬 수 있는 것이다.In this way, the present invention is a packing (3) of the same length as the bushing (2) by inserting and detaching the packing (3) of the single body formed in the same shape as the bushing (2) in the shaft hole (1) of the bushing (2). Since it is in close contact with the piston rod, it has excellent airtightness, so that no fluid leaks out. As the conventional packing 3 is worn out, the closed end of the bushing body rubbing with the piston rod is eliminated, thereby extending the life of the cylinder. It is.

그리고 패킹(3)은 부싱(2) 내벽의 홈(4)과 요철부(5)(5')가 서로 감합되어 있으므로 부싱(2)과 결합이 튼튼하고 교체시에도 손쉽게 빼낼수 있으므로 삽탈자재가 용이한 잇점이 있다.In addition, the packing 3 has a groove 4 and an uneven portion 5 and 5 'of the inner wall of the bushing 2 so that the packing 3 is securely coupled with the bushing 2 and can be easily removed during replacement. There is an easy advantage.

이와같이 본 고안은 패킹(3)을 부싱(2)과 동일형상으로 형성한 단일체로 형성하므로 기밀이 우수하여 유체의 누설을 방지하고 피스톤롯드를 마손시키는 폐단이 없어 실린더의 수명을 연장시킬 수 있는 효과가 있다.As such, the present invention forms the packing 3 as a single body formed in the same shape as the bushing 2, so that the airtightness is excellent, thereby preventing the leakage of fluid, and there is no closed end to wear the piston rod, thereby extending the life of the cylinder. There is.
