Abstract
A roll stand for rolling metallic strips includes at least one roll or cylinder which is respectively mounted in a mounting on rolling bearings in the region of its end journals, and at least one distributing device for distributing a lubricant-gas flow. The roll stand according to the invention makes it easily possible in an operationally reliable manner to supply a rolling bearing, provided for mounting a roll or cylinder, with a precisely determined amount of lubricant. This is achieved according to the invention in that a connecting channel for the transport of a lubricant-gas flow to or from the distributing device is molded into the roll or cylinder.
Claims20
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;
- and
- a 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.
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;
- and
- a 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.
