To provide an aircraft landing gear lifting gear structure capable of lowering a landing gear by releasing connection between an output of a motor and an electrical linear actuator during emergency with a simple configuration.SOLUTION: A gear engagement releasing structure 40 comprises: a first gear 41 connected to a motor; a fitting pin 44 connected to the first gear 41 to extend in a direction perpendicular to an axial direction of the first gear 41; a ring-shaped pin guide 46 having a pin insertion groove into which the fitting pin 44 can fit; a second gear 42 connected to the ring-shaped pin guide 46 and an electrical linear actuator; and a slide shaft 43 provided inside the first gear 41, the ring-shaped pin guide 46, and the second gear 42 in a radial direction, to which the fitting pin 44 is connected. The slide shaft 43 is configured to be movable to a first position where the fitting pin 44 and the ring-shaped pin guide 46 are engaged with each other and a second position where the fitting pin 44 and the ring-shaped pin guide 46 are disengaged from each other.SELECTED DRAWING: Figure 2
【課題】簡単な構成で、緊急時にモータの出力と電動リニアアクチュエータとの接続を解除して降着装置を下降させることができる、航空機用降着装置昇降ギア構造を提供する。【解決手段】ギア結合解除構造４０は、モータに接続された第１ギア４１と、第１ギア４１に接続され第１ギア４１の軸方向に垂直な方向に延びる嵌合ピン４４と、嵌合ピン４４が嵌合可能なピン挿入溝を有する輪状ピンガイド４６と、輪状ピンガイド４６と、電動リニアアクチュエータとに接続された第２ギア４２と、第１ギア４１、輪状ピンガイド４６及び第２ギア４２の径方向内側に設けられ、嵌合ピン４４が接続されたスライドシャフト４３とを備える。スライドシャフト４３は、軸方向に沿って、嵌合ピン４４と輪状ピンガイド４６とが嵌合される第１位置と、嵌合ピン４４と輪状ピンガイド４６との嵌合が解除される第２位置とに移動可能に構成されている。【選択図】図２
