Claims (5)

  1. 외측트랙표면을 갖는 샤프트와 ; 상기 샤프트를 에워싸고 내측트랙표면을 갖는 외측링과 ; 상기 샤프트의 원주방향으로 서로 이격된 관계에서 상기 샤프트와 상기 외측링사이에 배치되어서 상기 외측링의 외측원주표면이 장치의 요소의 트랙표면과 구름접촉하도록 하는 구름요소와 ; 상기 샤프트상에 제공되고 사이에서 한정되는 작은 갭으로 상기 요소의 상기 트랙표면에 대향하는 하중지지부를 구비하는 돌출부로 이루어지고 상기 돌출부는 설정치보다 더큰 레이디얼하중이 상기 외측링에 작용할때 상기 요소의 상기 트랙표면이 상기 돌출부의 상기 하중지지부에 접할 수 있도록 구성된 것을 특징으로 하는 구름접촉장치.
  2. 제 1 항에 있어서, 상기 돌출부가 상기 샤프트에 삽입되는 환상부재인 것을 특징으로 하는 구름접촉장치.
  3. 제 1 항에 있어서, 상기 돌출부가 상기 샤프트와 일체로 형성된 환상부재인 것을 특징으로 하는 구름접촉장치.
  4. 제 1 항에 있어서, 상기 하중지지부가 상기 돌출부의 원주에 위치되고 상기 요소의 평평한 표면에 대향하는 평평한 표면을 포함한 것을 특징으로 하는 구름접촉장치.
  5. 제 1 항에 있어서, 상기 갭이 장치의 통상 작동중에 가해지는 최대 레이디얼하중에 의해 야기되는 상기 외측링의 레이디얼탄성변형과, 상기 돌출부의 상기 하중지지부와 상기 요소의 상기 트랙표면사이에 존재하는 윤활유막의 허용최소두께의 합보다 더 크고, 상기 갭이 상기 샤프트의 굽힘에 인하여 상기 외측링의 변위와 상기 외측링의 레이디얼 탄성변형의 합보다 더 작으며, 상기 외측링의 변위와 후자의 탄성변형의 값은 상기 돌출부가 제공되지 않고 기초적인 정적공칭하중이 상기 외측링에 가해진다는 가정하에 달성가능한 것에 대응 하는 것을 특징으로 하는 구름접촉장치.
    ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
