摘要： A system is disclosed for use in a rolling mill oil film bearing (10) to remove a laminar flow of oil exiting tangentially from between a rotating sleeve (12) and a fixed bushing (18) surrounding the sleeve (12). The system comprises confinement surfaces cooperating with the sleeve (12) and the bushing (18) to define an annular chamber (40a) arranged to receive the exiting laminar flow of oil. Impellers (42) project into the chamber (40a) and are rotatable with and at the velocity of the sleeve (12) to thereby propel the oil around the annular chamber (40a). An outlet (44) communicates tangentially with the annular chamber (40a) for removing oil being propelled around the chamber (40a) by the rotation of the impellers (42). The size of the outlet (44) in relation to the volume of oil received in the annular chamber (40a) is such that the chamber (40a) remains filled with oil during steady state operation of the bearing (10).
摘要翻译：公开了一种用于轧机油膜轴承（10）中以从围绕套筒（12）的旋转套筒（12）和固定衬套（18）切向离开的油层的液流的系统。该系统包括与套筒（12）和衬套（18）配合的限制表面，以限定布置成接收出射的层流的油的环形室（40a）。叶轮（42）突出到室（40a）中并且可以以套筒（12）的速度旋转，从而将油推进环形室（40a）。出口（44）与环形室（40a）相切地连通，用于通过叶轮（42）的旋转去除围绕室（40a）推进的油。出口（44）的尺寸相对于在环形室（40a）中容纳的油的体积大小使得在轴承（10）的稳态操作期间，腔室（40a）保持充满油。

摘要： A rolling mill laying head (22) comprises a quill (24) rotatable about a central axis (X). A guide pipe (26) carried by the quill (24) and is configured and arranged to form a longitudinally moving product into a continuous series of rings. Axially spaced bearings (30, 32) support the quill (24) on a stationary support structure (28) for rotation about its axis. At least one of the bearings (30, 32) comprises a hydrostatic oil film bearing.

摘要： A sleeve is disclosed for use in an oil film bearing of the type employed to rotatably support the tapered neck of a roll in a rolling mill. The sleeve is machined from a hollow forging of a base metal with a cylindrical outer surface and a tapered inner surface adapted to be seated on the tapered roll neck. The tapered inner surface of the sleeve is coated with a layer of material that is chemically dissimilar with respect to the base metal.
