Abstract: A torque coupling (13) for a rotor head (11) of a rotary-wing aircraft has upper and lower plates (29, 31) configured for rotation with a rotor mast (19). Drive links (33) pivotally connected to the upper and lower plates (29, 31) pivot about a pivot axis generally parallel to and radially offset from an axis of rotation of the plates. Each link (33) is engaged with adjacent drive links (33) to form a continuous ring of links, such that motion of one link (33) about its pivot axis causes motion in an opposite direction of each adjacent link (33) about its pivot axis. Drive elements (25) connect the drive links (33) to an assembly configured to receive rotor blades. The drive elements (25) may be components of a universal joint, a multiple trailing-link configuration, a pad-bearing configuration, or another type of articulating assembly.

Abstract translation: 用于转翼飞行器的转子头（11）的扭矩联接器（13）具有被配置为与转子桅杆（19）一起旋转的上板和下板（29,31）。 枢转地连接到上板和下板（29,31）的驱动连杆（33）围绕大致平行于板的旋转轴线并且径向偏移的枢转轴线枢转。 每个连杆（33）与相邻的驱动连杆（33）接合以形成连续的环形环，使得一个连杆（33）围绕其枢转轴线的运动引起每个相邻连杆（33）围绕其枢轴的相反方向的运动 枢轴。 驱动元件（25）将驱动连杆（33）连接到被配置为接收转子叶片的组件。 驱动元件（25）可以是万向接头，多拖尾构造，衬垫承载构造或另一类型的铰接组件的组件。

Abstract: An aircraft rotor assembly (104) has a yoke (110) defining a plurality of bearing pockets (114). Each bearing pocket houses an axisymmetric elastomeric spherical bearing (116) at least partially therein. The axisymmetric elastomeric spherical bearings (116) comprise flap, lead-lag, and pitch hinges for rotor blades (106) coupled thereto. The rotor blades (106) maintain a first in-lane frequency of less than 1/rev through the use of damper assemblies (142) coupled between adjacent blades (106).
