To provide a transmission for a helicopter, which improves continuous driving capability by appropriately lubricating a bearing in the event of emergency of a main lubricating circuit while jetting a sufficient amount of lubricating liquid to the main lubricating circuit in normal time.SOLUTION: A transmission lubricating structure comprises a power transmission shaft 3, a main lubricating circuit 11 and an auxiliary lubricating circuit 12. The power transmission shaft has an injection hole 3d that allows an internal space to communicate with the outside. The main lubricating circuit has: a main nozzle 23 having a nozzle hole 32a through which lubricant supplied from a main tank 21 is ejected into the internal space S of the power transmission shaft; and a hydraulic pump 22 that pumps the lubricant from the main tank to the main nozzle. The auxiliary lubricant circuit is disposed outside the power transmission shaft and lower than the auxiliary tank 31 and higher than an object to be lubricated, and has an auxiliary nozzle 32 by which the lubricant supplied from the auxiliary tank by its own weight is dropped toward the object to be lubricated.SELECTED DRAWING: Figure 1

    【課題】主潤滑回路の正常時に十分な量の潤滑液を噴射しながらも、主潤滑回路の非常時に軸受を適切に潤滑して継続運転能力を向上させるヘリコプターのトランスミッションを提供する。【解決手段】トランスミッション潤滑構造は、動力伝達軸3、主潤滑回路11及び予備潤滑回路12を備える。前記動力伝達軸は、内部空間を外部に連通させる噴射孔3dを有する。前記主潤滑回路は、主タンク21から供給された潤滑油を前記動力伝達軸の前記内部空間Sに吐出するノズル孔32aが形成された主ノズル23と、前記主タンクから前記主ノズルに前記潤滑油を圧送する油圧ポンプ22と、を有する。前記予備潤滑回路は、動力伝達軸の外部において予備タンク31よりも下方かつ潤滑対象よりも上方に配置され、前記予備タンクから自重で供給される潤滑油を前記潤滑対象に向けて滴下する予備ノズル32と、を有する。【選択図】図1
