4 SPIDEX® – the elastic coupling SPIDEX® – the elastic coupling Technical description Elastic couplings reduce intermittent short-period torsional shocks by briefly storing part of this shock energy elastically. Any degree of uneven movement and torque transference is consequently reduced. Elastic couplings suppress body resonance and therefore contribute to noise reduction. The elastic SPIDEX® coupling transmits the torque without the risk of breakdown and backlash-free. The convex generated profiled tooth crown, see Fig. 1, allows compensation of radial and angular displacements of the two...
