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 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.

초록

The invention relates to a cylinder in a rotary press, in particular, for interacting with a form cylinder for a gravure press. According to the invention, the cylinder is improved with regard to its variable adaptability by the provision of a linear drive located at the end of the cylinder between the fixed support and rotating outer surface. Said linear drive operates in a vertical radial direction upwards toward the inner ring of a roller bearing,

1. A cylinder comprising:an inner, stationary support, said support having a first end and second end;an outer rotatable jacket on said support;at least first and second rolling bearings positioned between said support and said jacket, said rolling bearings supporting said jacket for rotation about said support;a lubricant and coolant fluid circuit between said support and said jacket, said at least first and second rolling bearings being in contact with a fluid in said lubricant and coolant fluid circuit;a fluid inlet located at one of said first and said second ends of said support and a fluid outlet located at the other of said first and said second ends of said support; andat least one actuating device engageable with a first one of said rolling bearings, said actuating device being operable to vary a first radial spacing between said jacket and said support, said second rolling bearing fixing a second radial spacing between said jacket and said support, said first rolling bearing and said actuating device being arranged at a first end of said jacket. 2. The cylinder of claim 1 further including a third rolling bearing and a second actuating device arranged at a second end of said jacket, said third rolling bearing being in contact with said fluid in said lubricant and coolant fluid circuit. 3. The cylinder of claim 2 wherein said second rolling bearing is between said first and third rolling bearings. 4. The cylinder of claim 1 wherein said first rolling bearing is a deep groove ball bearing. 5. The cylinder of claim 1 wherein said actuating device is a working cylinder. 6. The cylinder of claim 5 wherein said working cylinder is adapted to be charged with a working fluid at a hydraulic pressure of between 10 bar and 95 bar. 7. The cylinder of claim 5 further including an inner ring of said first rolling bearing, said working cylinder acting against said inner ring. 8. The cylinder of claim 7 further including a bushing supporting said inner ring. 9. The cylinder of claim 5 further including an outer ring in said at least first rolling bearing and a concentrically arranged bushing supporting said outer ring. 10. The cylinder of claim 1 further including an outer surface for said jacket and an elastic cover on said outer surface. 11. The cylinder of claim 1 wherein said fluid inlet and said fluid outlet are sized to convey at least ten liters of fluid/minute. 12. The cylinder of claim 1 wherein said fluid has a pressure of at least two bar. 13. The cylinder of claim 1 wherein said cylinder is arranged in a rotary printing press. 14. The cylinder of claim 1 wherein said cylinder is a counter-pressure cylinder. 15. The cylinder of claim 14 wherein said counter-pressure cylinder is arranged in a rotogravure printing press. 16. A cylinder comprising:an inner, stationary support, said support having a first end and second end;an outer rotatable jacket on said support;at least first and second rolling bearings positioned between said support and said jacket, said at least first and second rolling bearings supporting said jacket for rotation about said support, said first rolling bearing being arranged at said first end of said support and said second rolling bearing arranged at said second end of said support;at least one fixed set of rolling bearings arranged between said first and said second rolling bearings;a first actuating device at said first end of said support and a second actuating device at said second end of said support, said first actuating device being engageable with said first rolling bearing and said second actuating device being engageable with said second rolling bearing, each of said actuating devices including a working cylinder with a single push rod; andeach of said first and said second actuating devices being operable to vary a first radial spacing between said jacket and said support, said at least one fixed set of rolling bearings fixing a second radial spacing between said jacket and said support. 1 7. The cylinder of claim 16 wherein each of said first and said second rolling bearings are deep groove ball bearings. 18. The cylinder of claim 16 wherein said working cylinder is adapted to be charged with a working fluid at a hydraulic pressure of between 10 bar and 95 bar. 19. The cylinder of claim 16 further including a lubricant and coolant fluid circuit between said support and said jacket, each of said first rolling bearing, said second rolling bearing, and said at least one fixed set of rolling bearings being in contact with a fluid in said lubricant and coolant fluid circuit. 20. The cylinder of claim 19 said jacket having an inner surface in contact with said fluid in said lubricant and coolant fluid circuit. 21. The cylinder of claim 19 further including a fluid inlet located at one of said first and said second ends of said support and a fluid outlet located at the other of said first and said second ends of said support, each of said fluid inlet and said fluid outlet being sized to convey at least ten liter of fluid/minute. 22. The cylinder of claim 19 wherein said fluid has a pressure of at least two bar.
