Coupling Element & Sizing ® TRASCO Jaw Couplings 4 www.jbj.co.uk/couplings.html #DriveLineHarmony The sum of the admissible value (A) and the respective values shown in the table must be less than or equal to 1. Dynamic torsional rigidity C is the first derivate of the nominal torque of half coupling in respect to the torsion angle. j is the torsion angle of half Tdin coupling in respect to the second half. As a general rule, C is greater than CT and depends on the stress acting on the coupling. Tdin Misalignment TKN j dj dTKN The values shown in the table for radial and angular misalignment, must be corrected in case they are simultaneously acting on the coupling.
