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.

1. Roll or cylinder for a roll stand, comprising a first end journal associated with an operating side of the roll stand and a second end journal associated with a drive side of the roll stand, wherein in the roll or cylinder: a first rolling bearing rotatably mounted on a circumferential surface of the first end journal and a second rolling bearing rotatably mounted on a circumferential surface of the second end journal;at least one seat is provided, wherein the at least one seat includes a first seat at the first end journal, in which first seat a first distributing device is inserted for distributing lubricant-gas flow to at least a first discharge line, said first discharge line being also provided within the roll or cylinder, said first discharge line leading to the first rolling bearing mounted on the circumferential surface of the first end journal of the roll or cylinder; anda connecting channel is provided for transporting the lubricant-gas flow from the first distributing device to a second discharge line leading to the second rolling bearing mounted on the circumferential surface of the second end journal, said first distributing device being connected to the connecting channel. 2. Roll or cylinder according to claim 1, wherein the first seat is molded into the first end journal. 3. Roll or cylinder according to claim 1, wherein the first seat for the first distributing device is molded into the first end journal, and wherein a second seat for a second distributing device is molded into the second end journal, wherein the second distributing device distributes lubricant-gas flow from the connecting channel to the second discharge line. 4. Roll or cylinder according to claim 3, wherein the first seat of the first end journal is interconnected by the connecting channel leading through the roll or cylinder to a second seat of the second end journal. 5. Roll or cylinder according to claim 4, wherein the connecting channel is aligned coaxially to the axis of rotation of the roll or cylinder. 6. Roll or cylinder according to claim 4, wherein the connecting channel is produced by two mutually joining bores, one of which is molded into the roll or cylinder from a first end face of the first end journal and the other is molded into the roll or cylinder from the second end face of the second end journal. 7. A roll stand for rolling metallic strips comprising at least one roll or cylinder of claim 1, which is respectively mounted in a mounting on rolling bearings in the region of its end journals, and comprising at least one distributing device for distributing a lubricant-gas flow. 8. A roll or cylinder for a roll stand, comprising: a first end journal associated with an operating side of the roll stand and a second end journal associated with a drive side of the roll stand;a first rolling bearing rotatably mounted on a circumferential surface of the first end journal and a second rolling bearing rotatably mounted on a circumferential surface of the second end journal;at least one seat extending into the roll or cylinder for flowing a lubricant-gas therethrough, wherein the at least one seat includes a first seat extending into the roll or cylinder at the first end journal associated with the operating side of the roll stand;a first discharge line leading to the first rolling bearing mounted on the circumferential surface of the first end journal;a second discharge line leading to the second rolling bearing mounted on the circumferential surface of the second end journal;a connecting channel that connects the first seat with the first discharge line at the first end journal and with the second discharge line at the second end journal; anda first distributing device inserted into the first seat, wherein the first distributing device divides the flow of the lubricant-gas into a first partial flow and a second partial flow and distributes the first partial flow to the first discharge line,wherein at least a portion of the second partial flow is distributed to the second discharge line. 9. The roll or cylinder of claim 8, further comprising a second distributing device inserted into at least one seat, wherein the second distributing device divides the second partial flow from the first distributing device into a third partial flow and a fourth partial flow and distributes the third partial flow to the second discharge line. 10. The roll or cylinder of claim 9, further comprising: a third discharge line leading to a circumferential surface of at least one of the first and second end journals; anda third distributing device inserted into at least one seat, wherein the third distributing device divides the fourth partial flow from the second distributing device into a fifth partial flow and a sixth partial flow and distributes the fifth partial flow to the third discharge line. 11. The roll or cylinder of claim 9, wherein a second distributing device is inserted into a second seat, and wherein the connecting channel connects the first seat with the second seat. 12. The roll or cylinder of claim 9, wherein the first and second distributing devices are inserted into the first seat. 13. The roll or cylinder of claim 8, wherein the first distributing device has a cylindrical housing, the diameter of which corresponds to the internal diameter of the seat. 14. The roll or cylinder of claim 8, wherein the at least one seat is formed in the first or second end journal as a cylindrical bore in an axial direction of the roll or cylinder. 15. The roll or cylinder of claim 8, wherein the first seat is molded into an end face of the first end journal and a second seat is molded into an end face of the second end journal. 16. The roll or cylinder of claim 8, wherein the first and second discharge lines are radially aligned with respect to the axial direction of the roll or cylinder. 17. The roll or cylinder of claim 8, wherein the connecting channel connects the first seat formed in the first end journal with a second seat formed in the second end journal. 18. The roll or cylinder of claim 17, wherein a diameter of the connecting channel is smaller than the diameter of the first and second seats such that a shoulder is formed. 19. The roll or cylinder of claim 18, wherein the shoulder is used to position the first distributing device. 20. The roll or cylinder of claim 8, wherein a tubular insert is used to position the first distributing device.
