Abstract
A device for elastic interconnection of two rotatable shafts consisting of a first sleeve intended to be connected to a first shaft end. The sleeve has a radial flange and a cylindrical, annular portion connected to the periphery of the flange. A second sleeve is intended to be connected to a second shaft end and to be surrounded by said cylindrical portion. A number of elastically deformable spherical elements are arranged in opposing recesses in said second sleeve and cylindrical portion and distributed around a shaft end. The recesses in the cylindrical portion are arranged in the end surfaces of plugs and provided with external threads. The plugs by being turned are displaceable in threaded bores provided radially in the wall of the cylindrical part. The outer end surfaces of the plugs are provided with diametrical grooves and the cylindrical portion is provided with a diametrical groove. The diametrical grooves and the peripheral grooves define an annular groove. A locking ring is disposed in the annular groove to lock all the plugs in a desired position.
