Modular approach to machine design predetermines the development of effective ways to connect the various modules (nodes).
Problem reduce of radial forces acting on the shaft output ends of nodes requires the development and test of couplings with increased compliance. To solve this problem the couplings with elastic elements of polymeric materials can be used.
Experimental study of elastic petal couplings allowed to determine the axial, radial, angular and torsional flexibility of couplings and to take into account the phenomenon of stress relaxation and creep that are typical for rubber-elastic elements. The high damping capacity and compensating ability of this type coupling are revealed.
The applicability of petal couplings to connect the nodes of different machines is proved.
