Beschreibung
Zusammenfassung:	A concentric cylinder drive assembly (1) used for the transmission of power in industrial machinery is disclosed. More specifically, a concentric drive assembly (1) with a hollow outer cylinder (5) having an internal surface with a bi-directional surface lay; an inner cylinder (3) having an external surface with a unidirectional surface lay oriented at a predetermined angle (phi) along the length of the cylinder; an annular channel established between the outer and inner cylinders having a predetermined gap (7); and a lubrication oil that substantially fills the annular channel is presented.
