A roller gerotor device is disclosed including an outer rotor (39) and an inner rotor (31), and a plurality of rollers (37) serving as teeth. The device includes a housing means (11,45,47) defining a first wear surface (67) disposed axially adjacent first axial end surfaces (55,63) of the rotors. The first wear surface cooperates with one of the rotors to define an annular fluid passage (83) and a plurality of fluid grooves communicating with the passage (83) and extending radially outward. At least a terminal portion of each of the grooves (87) is adjacent an axial end surface (59) of each roller member (37) as the rotors rotate. Each of the terminal portions (95) becomes progressively shallower in the direction of rotation of the rotors, thus building up fluid pressure in the fluid groove (87) to prevent gouging or galling of the roller end surface against the adjacent wear surface (67).

A bearing element having an adherent score-resistant coating on its surface comprising a carbonized layer of an organic resin in which the layer is carbonized by ion implantation. The ion implantation is controlled to not only provide graphite-like and diamond-like structures in the carbonized coating but to also produce chemical bonding between carbon atoms of the resultant coating and atoms of the bearing surface.

The heavy-duty performance of babbitt-lined, copper-lead based journal bearings is improved by a novel trimetallic barrier layer interposed between the babbitt and copper-lead layers. The trimetallic barrier layer contains the elements nickel, tin and copper in suitable proportions. In a preferred embodiment, the barrier layer consists of layers of nickel, tin and copper metals successively plated over the copper-lead base.

A shift yoke (10) defining contact pads (18, 20) for axially engaging contact surfaces (22) on a relatively rotating clutch member (12). Inlet ramps (34, 36) are provided at the upstream ends of the contact pads to provide an inlet (36) for directing lubricant between the axially engaging surfaces.
