An articulated coupling for shafts (10, 12) comprises two coupling hubs (18) connected by a coupling-sleeve (20), which in one embodiment Figure 2, comprises a central portion (44) and two end portions (36), each of which carries flexible drive transmission elements (34). A laterally and torsionally flexible shaft (22) is rotationally rigidly bolted to the coupling hubs (18) through flanges (26, 28) to transmit axial loads. As a safety measure, in order to guarantee stoppage of the machine set in which the coupling is installed in the event of the drive transmission elements breaking, the coupling hubs (18) and end portions (36) have interengageable teeth (30, 32). In another embodiment, Figure 4 the teeth (30, 32) provides the driving connection between the hubs, and comprises internal teeth (30) on the hubs and external teeth (32) on the sleeve (20). Abutment means (40, 42) are provided to act in the event of failure of the flexible bar. <IMAGE> |
