Abstract:
A system is disclosed for use in a rolling mill oil film bearing to remove a laminar flow of oil exiting tangentially from between a rotating sleeve and a fixed bushing surrounding the sleeve. The system comprises confinement surfaces cooperating with the sleeve and the bushing to define an annular chamber arranged to receive the exiting laminar flow of oil. Impellers project into the chamber and are rotatable with and at the velocity of the sleeve to thereby propel the oil around the annular chamber. An outlet communicates tangentially with the annular chamber for removing oil being propelled around the chamber by the rotation of the impellers. The size of the outlet in relation to the volume of oil received in the annular chamber is such that the chamber remains filled with oil during steady state operation of the bearing.
