Assembly of two objects articulated to each other with two degrees of freedom in rotation

摘要

Two objects are articulated together by a strong and compact joint which provides two rotational degrees of freedom about axes X and Y, and which comprises a bearing have a male inner ring swivel mounted in a female outer ring. The male inner ring is rotatably mounted on a shaft integral with one of the objects and defining the axis X, and the female outer ring is attached to the other object. The two rings are rotationally linked in the direction of an axis Z perpendicular to the X and Y axes by two flat support surfaces on the inner ring arranged between two flat guide surfaces in the outer ring, the said support surfaces and the said guide surfaces being parallel to the X and Z axes.
