Description

축 커플링의 개선된 결합구조{Rigid connection structure of shaft coupling}Rigid connection structure of shaft coupling

본 발명은 축 커플링에 있어 샤프트와 플랜지 상호 간의 결합 구조에 관한 것으로, 더욱 구체적으로는 플랜지와 샤프트 상호 간의 결합력을 현저히 증진시켜 고속으로 회전하는 샤프트가 장시간 동안 매우 안정적인 작동을 담보할 수 있는 축 커플링의 개선된 결합구조에 관한 것이다.The present invention relates to a coupling structure between a shaft and a flange in an axial coupling, and more specifically, a shaft capable of ensuring a very stable operation for a long time by a shaft rotating at high speed by remarkably enhancing the coupling force between the flange and the shaft. It relates to an improved coupling structure of the coupling.

풍력발전기 등에 있어 증속기와 발전기 사이에 위치하여, 구동부인 증속기로부터 전달되는 고속의 회전력을 피동부인 발전기로 전달하는 매개체가 축 커플링이다. 일반적으로 축 커플링은 증속기 및 발전기 각각과 연결되는 플랜지를 마련하고, 이들 플랜지 각각을 일정 길이의 샤프트로 연결하는 구조를 가진다.In a wind power generator or the like, a medium coupling is located between a speed increaser and a generator, and a medium for transmitting a high-speed rotational force transmitted from the speed increaser, which is a driving part, to a generator that is a driven part. In general, the shaft coupling has a structure in which a flange is connected to each of the gearbox and the generator, and each of these flanges is connected to a shaft of a certain length.

근자 이러한 구조의 축 커플링에 있어서 샤프트는 고속의 회전력을 장시간 안정적으로 전달해야 하는데, 근자 샤프트의 소재로 그 중량 자체는 가벼우면서도 일정 수준 이상의 고강도를 오랜 시간동안 유지할 수 있음은 물론 비틀림이나 휨 변형이 발생하는 경우 자체 변형을 통해 보상이 가능한 유리섬유강화 플라스틱(GFRP, glass fiber reinforced plastics)이 각광받고 있다.In the shaft coupling of this structure, the shaft must stably transmit a high-speed rotational force for a long time. As a material of the root shaft, the weight itself is light, and it can maintain a high strength over a certain level for a long time, as well as torsion or bending deformation. When this occurs, glass fiber reinforced plastics (GFRP), which can be compensated through self-deformation, are in the spotlight.

한편, 축 커플링에 있어 증속기 및 발전기 각각과 직접 연결되는 플랜지는 주로 철과 같은 금속소재로 이루어지는데, 금속 재질로 이루어지는 플랜지와 합성수지 재질로 이루어지는 샤프트의 이질적인 특성을 감안하여, 관련 업계에서는 접착제를 이용하여 플랜지와 샤프트 상호 간을 결합하는 방식을 사용하고 있다.On the other hand, in the shaft coupling, the flange directly connected to each of the gearbox and the generator is mainly made of a metal material such as iron. Considering the heterogeneous characteristics of a flange made of a metal material and a shaft made of a synthetic resin material, adhesives in related industries It uses the method of coupling between the flange and the shaft by using.

그런데, 이처럼 샤프트와 플랜지 상호 간을 단순히 접착제로서 결합하게 되면, 장시간 주변의 온도 변화에 노출됨에 따라 접착제의 결합력이 저하되는 문제가 있으며, 플랜지를 통해 샤프트에 강한 토크가 전달되는 경우 샤프트 자체가 방사상으로 벌어지며 플랜지와 분리되는 현상이 발생하여 장치 자체가 파손되는 심각성이 있었다.However, if the shaft and the flange are simply bonded to each other as an adhesive, there is a problem in that the adhesive force of the adhesive decreases as it is exposed to a change in ambient temperature for a long time. When a strong torque is transmitted to the shaft through the flange, the shaft itself is radial. There was a serious phenomenon that the device itself was broken due to the phenomenon of separation from the flange.
