The elastic coupling is a coupling that connects the two coupling halves to connect and transmit the torque by the elastic elements that absorb, buffer and compensate the relative displacement of the two shafts of the mechanical transmission system. The high elastic coupling is mainly characterized by that the elastic deformation strength and fatigue strength of the elastic element are higher than that of the ordinary elastic coupling. The performance of the elastic element is high performance rubber, polyester polyurethane, MC nylon.

The main elastic element of the highly flexible coupling is a rubber component with a high torsional bearing strength. The rubber component can be designed in a single row or multiple rows. Each rubber assembly has a plurality of standard rigidity options, and the mother of the two coupling halves can be selected. The strength and fatigue strength are also higher, and the stiffness requirements determined by the torsional vibration calculation can be satisfactorily met. The main purpose of using a highly flexible coupling in ship power systems is to transmit power and torque, compensate for radial, axial and angular misalignment, and compensate for oscillations in rotational momentum. Adjust the system natural frequency.

High elasticity rubber couplings are classified into tire couplings, saddle-shaped elastic couplings, and multi-angle rubber couplings. The high-flexibility couplings are lightweight, easy to install, and have a large amount of displacement compensation and large damping. The ability to absorb vibration and strong frequency modulation can better protect the host, gearbox and shafting.
