The flexible claw coupling N (ELKU-N) is a positive-locking, torsionally flexible coupling which allows radial, axial and angular displacement between the driving and the driven shafts. It is a fail-safe coupling. The torque will be transmitted by the flexible buffer set fitted in the buffer part and distributed symmetrical arround the circumference of the coupling.
The claws of the claw ring(type A) or claw part (type B) are operating in the space between the buffers.
The buffers are subjected to compression. That`s why there´s a low wear and high loading capacity.
The high damping of the coupling protects the drive from excessive dynamic overloading. The progressively rising spring charcteristic allows a rapid reduction of energy oscillations and limits their amplitude.

Perfect operation can be guaranteed at a working temperature of – 30 °C to + 80 °C.

Types:
type A: three parts design;
type B: two parts design;
type S1: design with brake disk;
type S2: design with radial dismountable brake disk;
type H: design with spacer.
