torsionally Flexible Coupling with T-PUR
ROTEX jaw type couplings are characterised by small dimensions, light weight and low mass moments of inertia yet transmit high torques. The 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.
ROTEX are torsionally flexible and designed for positive torque transmission, and they are fail-safe. Operational vibrations and shocks are efficiently dampened and reduced, and two congruent coupling halves with concave claws on the inside are peripherally offset in relation to one another by half a pitch. They are designed to enable an involute spider to be located between them.
These couplings are capable of compensating for axial, radial and angular displacements of the shafts that are connected. The maximum torsion angle amounts to 5°, and they can be fitted both horizontally or vertically.
The flexible teeth of ROTEX products are subject to pressure only, and this gives the advantage of the individual teeth being ability to withstand considerably higher loads. The elastomer parts show deformation with excessive loads and speeds, so sufficient space for expansion should be given.
ATEX Explosion-Proof Use
ROTEX couplings are suitable for power transmission in drives used in hazardous areas. They are certified according to EC standard 94/9/EC (ATEX95) as units of category 2G/2D, therefore are suitable for use in hazardous zone areas 1, 2, 21 and 22.
