KWD ELKU-N B 250 - 20 H7P1(x35)- 16 H7P2(x25) KWN 22013 - Coupling

technical featuresThe flexible claw coupling N (ELKU-N) is a positive-locking, torsionallyflexible coupling which allows radial, axial and angulardisplacement between the driving and the driven shafts. It is afail-safe coupling.The torque will be transmitted by the flexible buffer set fitted in thebuffer part and distributed symmetrical arround the circumferenceof the coupling.The claws of the claw ring(type A) or claw part (type B) are operatingin the space between the buffers.The buffers are subjected to compression. That`s why there´s alow wear and high loading capacity.The high damping of the coupling protects the drive from excessivedynamic overloading. The progressively rising spring charcteristicallows a rapid reduction of energy oscillations and limits theiramplitude.Perfect operation can be guaranteed at a working temperature of- 30 °C to + 80 °C.The standard hub material is grey cast ironEN-GJL-250-DIN EN 1561.1561.Claw Ring.Buffer Part.Hub
