Abstract

진동식 작동기용 베어릴시일조립체는: 외측 베어링 궤도면과, 상기 외측 베어링 궤도면과 동심으로 장착된 내측베어링 궤도면과, 축방향 길이는 반경의 1/10이하이며, 상기 내측 베어링 궤도면에 밀봉 고정되는 내주연부와 상기 외측 베어링궤도면에 밀봉 고정되는 외주 연부를 구비하여, 상기 내측 궤도면과 상기 외측 궤도면간의 상대적 회전이 축방향 비틀림을 최소로 한채 제한적으로 발생할 수 있도록 된 환상의 변형가능한 액체 불투과성 멤브레인을 포함한다. 일실시예에 있어서, 멤브레인은, 신장되어, 비틀림 응력을 받아 표면이 일그러지는 현상을 제거한다. 또다른 실시예는 비틀림을 감소시키기 위해서 멤브레인내로 성형된 웨이브를 도시한다.

Description
