FLENDER Standard Couplings Torsionally Rigid All-Steel Couplings — ARPEX ARP-6 Series © Siemens AG 2015 General information Power ratings, type MCECM 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 permitted shaft misalignment Δ K r applies to the shaft distance S specified in each case. 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.
6 T Kmax permitted only five times per hour.
