연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison, Kafe, Webinar 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

A device for damping vibrations comprising at least two coaxially arranged damper parts rotatable relative to each other to a limited extent in the circumferential direction, coupled by torque transmitting means and damping coupling means, which exhibit at least one energy accumulator unit, and forming the impingement areas for the energy accumulator units. At least one damper part forms a guide channel for the energy accumulator units. The individual impingement area on the damper part forming the guide channel for the energy accumulator units is formed by a stop element, connected in a torsion proof manner at least indirectly to the damper part and forms the abutment faces in the guide channel in the circumferential direction. The abutment face is capable of supporting the energy accumulator unit on both sides of the impingement area on the energy accumulator unit and is a part of the other damper part.

The device as claimed in claim 5, wherein the stop and support region is configured so as to be adapted to the contour of the wall of the first damper part that is missing in these regions, said first damper part forming the guide channel for the at least one first spring unit. 7. The device as claimed in claim 1, wherein the stop element is connected in a torsion proof manner directly to the damper part forming the guide channel for the at least one first spring unit. 8. The device, as claimed in claim 7, wherein the connecting region of the stop element forms an abutment face for resting against the first damper part. 9. The device as claimed in claim 1, wherein the stop element is connected in a torsion proof manner to a component which is connected in a torsion proof manner to the first damper part. 10. The device, as claimed in claim 9, wherein the openings are arranged in order to arrange the connecting region of the stop element in an axial plane with the first damper part. 11. The device as claimed in claim 9, further comprising torsion proof connections between the stop element and the component, which is connected in a torsion proof manner to the first damper part, and a torsion proof connections between the first damper part and the component, which is to be connected in a torsion proof manner to said damper part, ensuing on a common arrangement diameter. 12. The device as claimed in claim 1, further comprising torsion proof connections configured as riveted connections. 13. The device, as claimed in claim 12, wherein individual riveted connections are formed by respective rivet pins, which are formed or drawn into components that are to be connected together. 14.
