According to the speed reducer device for the aviation turboprop engine, a forward flight oil return opening communicates with the interior of a speed reducer body and an oil return integrated cavity, and a reverse flight oil return opening communicates with the interior of the speed reducer body; the first plugging structure is provided with a forward flying communication working position communicating with the oil return integrated cavity and the main oil return oil way and an inverted flying disconnection working position disconnecting the oil return integrated cavity and the main oil return oil way, and the second plugging structure is provided with an inverted flying communication working position communicating with the inverted flying oil return opening and the main oil return oil way. The forward flying disconnecting working position is used for disconnecting the reverse flying oil return port and the main oil return path; when the speed reducer body is positively arranged, the reverse flying oil return opening is located above the forward flying oil return opening, the first plugging structure is located at a forward flying communication working position, and the second plugging structure is located at a forward flying disconnection working position; when the speed reducer body is inverted, the inverted oil return opening is located below the forward oil return opening, the first plugging structure is located at the inverted disconnecting working position, and the second plugging structure is located at the inverted communicating working position. And air suction during oil return can be avoided.
本发明公开了航空涡桨发动机用减速器装置,正飞回油口与减速器本体内部和回油集成腔连通,倒飞回油口与减速器本体内部连通;第一封堵结构具有连通回油集成腔和总回油油路的正飞连通工作位置,以及断开回油集成腔和总回油油路的倒飞断开工作位置,第二封堵结构具有连通倒飞回油口和总回油油路的倒飞连通工作位置,以及断开倒飞回油口和总回油油路的正飞断开工作位置;当减速器本体正置时倒飞回油口位于正飞回油口的上方,第一封堵结构位于正飞连通工作位置,第二封堵结构位于正飞断开工作位置;当减速器本体倒置时倒飞回油口位于正飞回油口的下方,第一封堵结构位于倒飞断开工作位置,第二封堵结构位于倒飞连通工作位置。能避免回油时吸入空气。
