    摘要： A hub system comprises at least one yoke, at least one shear bearing, and at least one mast adapter. The at least one mast adapter is configured to support the at least one yoke and the at least one shear bearing, and the at least one yoke has a flapping hinge that is non-coincident with a flapping hinge of the at least one shear bearing. Another hub system comprises a stacked yoke and a mast adapter. The mast adapter is configured to transfer rotation from a rotor mast to the hub system to rotate the hub system about a central axis of rotation. The mast adapter is further configured to support the stacked yoke such that each yoke in the stacked yoke is configured to accommodate at least some amount of rotation about an axis that is perpendicular to or about perpendicular to the central axis of rotation.

    摘要翻译： 毂系统包括至少一个轭，至少一个剪切轴承和至少一个桅杆适配器。 所述至少一个桅杆适配器构造成支撑所述至少一个轭和所述至少一个剪切轴承，并且所述至少一个轭具有与所述至少一个剪切轴承的扑动铰链不重合的扑动铰链。 另一个集线器系统包括堆叠的轭和桅杆适配器。 桅杆适配器被配置为将旋转从转子桅杆传递到轮毂系统，以围绕中心旋转轴线旋转轮毂系统。 桅杆适配器还被配置为支撑堆叠的轭架，使得堆叠的轭架中的每个轭架构造成适应围绕垂直于或大致垂直于中心旋转轴线的轴线的至少一定量的旋转。

    摘要： A flexible joint assembly for providing flexure to a rotor blade comprising an upper hub plate and a lower hub plate configured to secure a rotor blade yoke via a bolted joint located radially outward of a mast; and an upper flexure assembly connected to the upper hub plate and a lower flexure assembly connected to the lower hub plate, wherein the upper flexure assembly and lower flexure assembly are configured to promote flapping of the rotor blade yoke about a flapping hinge located radially outward of the bolted joint.
