ABSTRACT:
A universal coupling comprising an outer element integral with a first shaft having a spherical cavity inside which are formed grooves, an inner element integral with a second shaft and having an external surface in which grooves are also formed whose bottom has a section through a plane passing through the axis of the inner element formed by an arc of a curve, rolling means being disposed between the pairs of grooves, these rolling means being held in the windows of a cage. The inner element has on its outer surface a cylindrical surface portion situated substantially in the median region in the axial direction and extending at least substantially as far as the plane orthogonal to the axis containing the points of the bottoms the furthest from the axis, this portion being extended on each side by spherical surface portions intended to mate with the inner surface of the cage.
