FLENDER Standard Couplings Torsionally Rigid All-Steel Couplings — ARPEX ARF-6 Series © Siemens AG 2015 General information Design of the ARF coupling Further application-specific coupling types are available in selection module X.CAT NG at www.siemens.com/couplings . Dimension sheets and further information are available on re- quest. ■ Technical data Power ratings, types GG and GJ 6 The permitted shaft misalignments Δ K a , Δ K r and Δ K w are maxi- mum values and must not occur at the same time (see following table). The values for torsional stiffness apply to the complete coupling. The torsional stiffness of the plate packs applies to the rated coupling torque T KN .
To determine the torsional stiffness for a specific operating point, e.g. for calculating torsional vibration, the manufacturer must be consulted. T Kmax permitted only five times per hour.
