ABSTRACT:
A hydrodynamic bearing (16) for a cutter cone assembly (12) that rotates around a journal (14). The bearing (16) comprises a plurality of grooves (88) on an outer surface (90) to produce undulations (82) on an inner surface (84) upon insertion of the bearing (16) into a bearing recess (94). Undulations (82) act as pockets to collect lubricant which is forced upon rotation of the bearing (16) between the outer journal surface (86) and the inner bearing surface (84) to produce a hydrodynamic film.
