Oil outlet for rolling mill oil film bearing
First Claim
1. An oil outlet for a rolling mill oil film bearing in which a bushing is fixed within a chock, the bushing has an internal bearing surface surrounding a rotating journal surface of a roll, oil is introduced into a gap between the journal and bearing surfaces, and the thus introduced oil is rotatably propelled by the rotating journal surface before escaping tangentially from opposite ends of said gap, said oil outlet comprising:
- a cover defining a groove adjacent to an end of said gap, said groove being positioned and configured to receive oil escaping from said gap and to redirect said oil along a circular path; and
an exit passageway communicating with said groove, said passageway being arranged substantially tangentially with respect to said circular path to receive oil escaping from said groove.

The oil outlet comprises a cover defining a groove adjacent to an end of the gap. The groove is positioned and configured to receive oil escaping from the gap and to redirect the oil along a circular path. An exit passageway communicates with the groove and is arranged substantially tangentially with respect to the circular path to receive oil escaping from the groove.
