영구자석을 이용한 동력전달축의 연결장치{POWER TRASMISSION SHAFT CONNECTING DEVICE USING PERMANENT MAGNETS}Power transmission shaft connecting device using permanent magnets {POWER TRASMISSION SHAFT CONNECTING DEVICE USING PERMANENT MAGNETS}

본 발명은 각종 식품기계, 의료기기, 산업용기계에 사용되는 동력 전달축을영구자석을 이용하는 장치에 관한 것이다. 좀더 자세하게는 자기등방성(磁氣等方性 -lsotropy)을 이용하여 자속밀도를 극대화시키므로서 자력의 힘만으로 단절된 무접속 회전축(shaft)의 동력 전달시에 안정된 동력전달을 확보 할 수 있고, 또한 과부하가 발생시에 자체 미끄럼 현상으로 모우터 및 감속장치에 무리가 따르지 않아 수명을 연장시킬 수 있을 뿐 아니라, 꾸준한 연구 개발을 계속 하게 되면 고도의 정밀을 요구하거나, 아주 큰 동력의 전달이 가능치 못할 것이라고 생각되던 부분까지 적용 할 수 있게한 영구자석을 이용한 동력전달축의 연결장치에 관한 것이다.The present invention relates to a device using a permanent magnet as a power transmission shaft used in various food machines, medical devices, and industrial machines. More specifically, by maximizing the magnetic flux density by using magnetic isotropy, it is possible to secure stable power transmission during power transmission of a disconnected shaft that is disconnected only by the magnetic force. Will not only increase the motor and deceleration time due to its own sliding phenomenon, but will also require high precision or the transmission of very large powers if the continuous research and development continues. The present invention relates to a power transmission shaft connecting device using permanent magnets, which can be applied to even existing parts.

종래에는 영구자석을 이용한 무접속 동력전달장치가 산업전반에 활용되지 못한 까달은 모우터의 175rpm이상의 회전력과 감속기를 사용시에 전달되는 회전력을 견딜 수 있는 강력한 영구자석이 개발되지 못하고, 또한 자력전달장치의 효능이 없었다. 따라서 동력전달 회전축을 기계적인 수단으로 연결하여 사용할 경우 급격히 과부하가 걸리어 충격을 받을 경우에는 동력전달 회전축이 파손되거나, 감속장치등에 무리가 뒤 따르게 되는 문제점이 있었다.In the related art, a connectionless power transmission device using permanent magnets has not been utilized in the entire industry, and a strong permanent magnet capable of withstanding the rotational power of 175 rpm or more of the motor and the transmission power of the reduction gear has not been developed. There was no efficacy. Therefore, when the power transmission rotary shaft is used by a mechanical means, the power transmission rotary shaft is damaged when it is suddenly overloaded and shocked, or there is a problem that the deceleration device follows.

본 발명은 상기한 바와 같은 문제점을 해소하기 위하여 자기등방성(磁氣等方性-lsotropy)을 이용하여 자속밀도를 극대화시키므로서 자력의 힘만으로 단절된 무접속 회전축(shaft)의 동력 전달시에 안정된 동력전달을 확보 할 수 있고, 또한 과부하가 발생시에 자체 미끄럼 현상으로 모우터 및 감속장치에 무리가 따르지 않아 수명을 연장시킬 수 있을 뿐 아니라, 꾸준한 연구 개발을 계속 하게 되면 고도의 정밀을 요구하거나, 아주 큰 동력의 전달이 가능치 못할 것이라고 생각되던 부분까지 적용 할 수 있게한 것이다.In order to solve the problems described above, the present invention maximizes the magnetic flux density by using magnetic isotropy, thereby stably powering the power of a disconnected shaft that is disconnected only by magnetic force. It can secure the transmission and extend the life of the motor and the reduction gear due to its own sliding phenomenon in the event of overload, as well as prolong the service life. It could be applied to the part where it was thought that the big power transmission would not be possible.
