Abstract
An improved structure for supporting a rotating shaft (22) in a liquid environment is disclosed. The bearing structure (28) has an inner support surface or smooth face (38) inwardly disposed and circumferentially engaging the rotating shaft (22). The smooth face (38) has a spiraling channel (46) formed therein, and the channel (46) extends from a first axial end of the bearing (28) which is open to the liquid environment, through some axial portion of the bearing (28) to introduce ambient liquid to lubricate the interface between the bearing (28) and that portion of the shaft (22) which it engages.
