    • A gearbox positioning device to position a gearbox relative to an engine case of a gas turbine engine. The positioning device has a first and second part, with the first part having a connecting cavity of predetermined shape and being secured to the engine case. The second part has a coupling post received in the connecting cavity and constraining displacement of the gearbox in a laterally transverse direction with respect to the central longitudinal axis of the engine. The device permits movement of the gearbox in the axial direction of the engine as well as angular movement to prevent stressing the engine case during thermal growth of the engine case or support linkage imbalance. A gearbox positioning system incorporating the positioning device and the method of attaching same to the engine casing is also included.
    • 齿轮箱定位装置,用于相对于燃气涡轮发动机的发动机壳体定位齿轮箱。 定位装置具有第一和第二部分,其中第一部分具有预定形状的连接腔并被固定到发动机壳体。 第二部分具有接收在连接腔中的联接柱并且相对于发动机的中心纵向轴线横向横向限制齿轮箱的位移。 该装置允许齿轮箱在发动机的轴向方向上的运动以及角度运动,以防止在发动机壳体或支撑连杆不平衡的热增长期间压缩发动机壳体。 还包括结合有定位装置的齿轮箱定位系统和将其连接到发动机壳体的方法。
