Abstract
Structure for and method of lubricating a rotating facing head or the like wherein the facing head is secured to a spindle rotatably mounted in a fixed frame for rotation with the facing head, including a lubricating ring concentric with the spindle and sleeved thereover secured to the frame, a lubricating passage extending radially through the lubricating ring, an annular groove between the lubricating ring and spindle in communication with the lubricating passage through the lubricating ring, radially extending passages through the spindle in communication at their outer end with the annular groove, sealing means for sealing between the inner surface of the lubricating ring and the outer surface of the spindle on each side of the ring, and an axially extending opening or passage within the spindle for passing lubricating fluid from the radially extending passages through the spindle axially of the spindle to the facing head. The method of lubricating the facing head while it is rotating includes passing lubricating fluid through the lubricating passage in the ring around the annular groove and through the radially extending passages and axially extending openings or passages in the spindle to the facing head. The lubricating fluid may be placed under pressure. In one modification of the invention, a pumping action for the lubricating fluid toward the facing head is provided by rotation of the spindle.
