ABSTRACT:
A tilting pad bearing for a rotatable surface includes a plurality of circumferentially-arranged tilting pads, each of the tilting pads having a working surface, a leading surface and a trailing surface. A lubrication device for lubricating fluid is detachably affixed to the tilt pad leading surface. The lubrication device may have an integrally-formed lubricant flow director with a radial or herringbone shape. The lubrication device has a pair of spaced ridges extending from the base of the device, the ridges being disposed at less than 180.degree. to each other. The ridges may also be parallel to the adjacent pad trailing surface. The ridges have wiper surfaces that wipe hot carryover lubricating fluid from the rotating surface. The hot lubricating fluid is directed by the ridges into an exit annulus or outlet apertures on opposite sides of the lubrication device.
