A positive lubrication delivery system for lubricating a rotatable gear comprises a stationary shroud configured and dimensioned to encompass a segment of the gear to be lubricated. The shroud defines with the gear segment, intermediate the circumferential outer surface of the gear segment and the adjacent surface of the shroud, a channel of diminishing clearance in the direction of gear rotation. Lubricant introduced into the channel is confined and subsequently caused to be spread over the circumferential outer surface of the gear in response to its rotation.
