A lubricated drive system for an accessory of a gas turbine engine which includes means for intermittently lubricating a splined interconnection between two shafts as well as means for lubricating a bearing for the shafts. Lubricant is supplied to an annular reservoir within one shaft, and this reservoir is kept full by centrifugal force when the shaft is rotating. During this period of rotation at a predetermined minimum speed, the excess lubricant supplied to the reservoir is discharged therefrom onto the bearing for the shaft or shafts, and when rotation of the shaft reduces below the minimum value or stops, the predetermined amount of lubricant within the annular reservoir spills therefrom onto a splined interconnection between the shafts so that it can centrifuge into the splines when rotation of the shafts begins.
