DYNAFLEX ELASTOMERIC FLEXIBLE COUPLINGS Page 111 of 124
Dynamic Torsional Stiffness, Kθ
The dynamic torsional stiffness is higher than the static stiffness at room temperature. When the LCD Series Couplings are attached to diesel engine fl ywheels, the elastomer gets warm. At an operating temperature in the 170° to 200°F range, the dynamic stiffness is nearly the same as the static stiffness at room temperature. The stiffness values shown in the performance characteristics chart are for computer modelling and in other types of torsional analysis work.
