Description

ABSTRACT:
A tilt pad bearing assembly for use in supporting a rotating shaft is disclosed. The bearing assembly includes lubricant means for effectively cooling separate individual bearing pads, and separate cooling channels for selectively cooling a portion of the bearing pad. The bearing pads each have a specific end treatment to act in combination to provide an anti-spragging effect. Additionally by selectively cooling a portion of the bearing pad, the bearing pad may have separate configurations for low speed and high speed applications such that boundary lubrication is achieved under low speed conditions and dynamic lubrication is achieved under high speed conditions.
