Ktr Rotex Coupling

Rotex jaw type couplings arecharacterizedby 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 anin-volutespider 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.

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.

Rotex spiders for coupling / roto spiders for coupling / gr spiders for coupling / elastic spiders for coupling / pu spiders for couplings / rubber spiders for couplings.

the improved polyurethane material t-pur® is resistant to significantly higher temperatures and has a considerably longer service life than the previous polyurethane material. From the visual point of view we have characterized the material t-pur® by the colours orange (92 shore-a), purple (98 shore-a) and pale green (64 shore-d). The previous spiders made from polyurethane in yellow, red and natural white with green ends will still be available. Up to size rotex® 90 inclusive single spiders are used. For rotex® couplings from size 100 to 180 the spider consists of dz tooth segments as a standard. The single spider will still be available in these sizes as an option.

spider materials are pu ( polyurethane ) t-pur / nitrile / steel jacketed / bronze jacketed / nylon / engineered plastic.
