Abstract: An example lubrication system for a rotating component has a primary lubrication system providing continuous lubrication during normal operation of the rotating component and secondary lubrication system with a reservoir co-rotating with the component. The reservoir is continuously replenished from the primary lubrication system during normal operation of the rotating system, with the lubricant being forced through a discharge orifice by the centrifugal force generated by the rotation toward, for example, a bearing or a gear. When the primary pressurized lubrication system fails, lubrication will continue to be provided by the lubricant in the supplemental lubricant reservoir while the rotation speed or power supplied to the shaft is controllably decreased in an emergency.
