ABSTRACT:
A bearing assembly for supporting a rotatable member, which includes a bearing casing with an inner surface and a fluid drain outlet, and pads mounted on the inner surface of the casing, is provided. Each pad has a face facing the rotatable member and has a leading edge and a trailing edge with respect to the rotation of the rotatable member. A spray bar is positioned adjacent the leading edge of each of the pads, and the spray bar has a fluid ejecting conduit positioned to forcibly eject lubricating fluid toward the leading edge and onto the pad face. The spray bar also includes a fluid blocking segment adjacent the rotatable member for blocking heated fluid from being carried by the rotation of the rotatable member to the leading edge of the next pad in the direction of the rotation, and a fluid removal segment in fluid communication with the fluid drain outlet. The fluid removal segment is obtusely inclined with respect to the fluid blocking segment for directing the heated fluid to the fluid drain outlet to expedite removal of the heated fluid from the bearing assembly.
