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.

Typical Applications

Dynafl ex LCD Series Couplings are useful for a wide range of rotary drive applications, from off-highway truck drivelines to auxiliary compressor drives on diesel loco- motives. The soft torsional stiffness of these couplings makes them ideally suited for diesel applications with remotely mounted driven components. Typical applica- tions include:

Typical End Product	Application
Mining Dump Truck	Increases Engine and Transmission Life
Diesel Locomotive	Eliminates Accessory Driveline Failure
Portable Air Compressor	Replaces Short-Lived Gear Coupling;
	Smooth Operation
4-Wheel Drive Farm	Reduces Noise and Extends Drive Train
Tractor	Life
Military Vehicle	Eliminates Accessory Shaft Breakage
Dynamometer	Prevents Driveline Failure
Mining Dump Truck	Prolongs U-Joint Life

In addition, Dynafl ex LCD Series Couplings have been used in these types of applications:

• Main Drive
Engine – Generator	Engine – Compressor
Engine – Transmission	Engine – Pump
Electric Motor – Pump	Electric Motor – Compressor
• Accessories
Starters	Fans and Blowers
Alternators	Power Take-Offs
