Abstract: The present invention includes a bypass apparatus for lubricant in an unregulated pressurized gearbox including: a block including a lubricant inlet in fluid communication with a pressure relief valve, wherein the pressure relief valve diverts lubricant into the gearbox or into an oil filter, wherein lubricant is returned to the gearbox when the lubricant is cold and/or pressure at the pressure relief valve is high to reduce damage to the gearbox caused by high pressure during a cold start, and when the lubricant temperature increases and the pressure is reduced the pressure relief valve closes and lubricant enters the oil filter.

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.
