6 #DriveLineHarmony N-Eupex & N-Eupex DS Technical Specifications Torsionally Flexible Couplings 1) Maximum speed for the respective type must be noted. For additional allowable shaft misalignment information, please refer to the operating instructions. For maximum coupling torque: T = 3,0 • T Kmax KN For coupling overload torque: T = 3.5 • T KOL KN For coupling fatigue torque: T = 0,15 • T , where T > T must be adhered to. KW KN N W N-EUPEX shaft distance S and radial misalignment ΔKr N-EUPEX (single-joint coupling) Radial misalignment ΔK and angular misalignment ΔK as well as changes in gap dimension are equalized in a elastomer r w joint. Values for Δ can be found in the respective type selection tables. S N-EUPEX DK (two-joint coupling) Radial misalignment ΔK and angular misalignment ΔK as well as changes in gap dimension are equalized in two r w elastomer joints. Values for Δ can be found in the corresponding type selection tables.
