Abstract
Self-contained modular joint adapted to interconnect two machine elements to permit a relative rotation of less than one revolution therebetween, wherein the first element comprises a strap consisting of a pair of wing-like extensions encompassing the second element in such a manner that said second element can pivot between said two wing extensions, each wing extension of said strap being provided with a bore concentric to the axis of said relative rotation, said bore being adapted to be engaged by members of revolution each adapted to center and position in the axial direction an inner race of rolling contact bearings capable of absorbing axial and radial efforts, the outer race of each one of said bearings being carried by a member of revolution centered and secured to said second element so as to constitute between said two elements a joint free of both axial and radial play, wherein one of said two members of revolution secured to said second element has fitted thereon the toothed annulus of a reduction gearing while the other element of said reduction gearing is secured to said member of revolution rigid with the wing extension of said strip which is opposite said member of r…
