Abstract:
This transmission lubrication structure for a helicopter is provided with a power transmission shaft, a main lubrication circuit and an auxiliary lubrication circuit. The power transmission shaft has an injection hole that allows communication from the internal space to the outside. The main lubrication circuit comprises: a main nozzle in which a nozzle hole is formed that discharges, to the internal space of the power transmission shaft, lubricating oil supplied from the main tank; and a hydraulic pump which pumps the lubricating oil from the main tank to the main nozzle. The auxiliary lubrication circuit has an auxiliary nozzle which, outside of the power transmission shaft, is arranged below an auxiliary tank and above the lubrication target, and which drips lubricating oil, supplied by its own weight towards the lubrication target, from the auxiliary tank.
