Description of coupling ROTEX® - couplings are characterized by small dimensions, low weight and   low mass moments of inertia yet transmit high torques. Running quality   and service life of the coupling are improved by accurate all-over   machining. Their application is ideal for transmitting torque while damping   torsional vibrations and absorbing shocks produced by the uneven   operation of certain prime movers. Performance In contrast to other flexible couplings, the intermediate members; of which are subject to bending stress and are therefore prone to; earlier wear, the flexible teeth of ROTEX couplings are subject to; pressure only. This gives the additional advantage of the individual; teeth being able to accept considerably higher loads.The elastomer parts; show deformation with load and excessive speeds. Sufficient space for; expansion should be ensured (see drawing – deformation with load). The maximum torsion angle with ROTEX couplings of any size amounts to 5°. They can be fitted both horizontally and vertically. Explosion-proof use
