    摘要： Improved flexible joint arrangements employ at least one flexure member that interfaces with wrapping surfaces defined on the bases to which the ends of the flexure member are connected. The flexure members are configured to define a traveling instantaneous axis of rotation that moves along a path defined by the interface of the flexure and the wrapping surfaces as the bases move relative to each other. The flexure members and the bases can be constructed of a monolithic material. The wrapping surfaces of the bases can be asymmetric in cross-sectional shape. The radius of curvature of the traveling instantaneous axis of rotation can be configured to change only in discrete quantum steps without reversals. In other embodiments, the flexible joint arrangement can be configured as one or more three bar linkages in which the middle bar is rigid and the outer bars are flexure members in accordance with the various embodiments.

    摘要翻译： 改进的柔性接头装置采用至少一个弯曲构件，其与限定在挠曲构件的端部连接的基部上的包裹表面相接合。 弯曲构件被构造成限定行进的瞬时旋转轴线，其随着基座相对于彼此移动而沿着由挠曲件和包裹表面的界面限定的路径移动。 弯曲构件和基座可以由整体材料构成。 基底的包裹表面的横截面形状可以是不对称的。 行进的瞬时旋转轴线的曲率半径可以被配置为仅在离散的量子步长而没有反转的情况下改变。 在其他实施例中，柔性接头装置可以被配置为根据各种实施例的一个或多个三个杆连杆，其中中间杆是刚性的，并且外部杆是挠性构件。
