Dynaflex® LCD Series Couplings

Rated: 75 to 2000 hp at 2000 rpm

LORD Dynafl ex LCD Series Couplings have been developed to overcome numerous torsional problems associated with vehicular and industrial driveline systems. These couplings increase equipment life by protecting against torsional vibration, shock and misalignment.

Typical application attachments include:

•Flywheel to shaft

•Flywheel to hub (splined)

•Shaft to shaft

•Floating shaft

Features and Benefits

•Protection from torsional shock loads

•Design fl exibility

•Safe for occasional severe overloads

•Vibration isolation – extremely low torsional spring rate is achieved with the Dynafl ex LCD Series Coupling, using elastomer in shear. This allows for low system natural frequencies and isolation of fi rst mode driveline disturbances.

•Damping at resonance – the elastomer used in Dynafl ex LCD Series Couplings effectively reduces vibration at resonance.

•Shock protection – torsional shock loads are attenu- ated by large shear defl ection of the elastomer. In the case of severe overloads, equipment damage is prevented by slippage between the elastomer and the outer housing.

•Misalignment accommodation – elastomer fl exibility allows for angular, parallel and axial misalignment.

•Long service life – Dynafl ex LCD Series Couplings have proven themselves under demanding and rugged service conditions.

•Maintenance-free – elastomer fl exibility accommo- dates all motion without wear, eliminates the need for lubrication.

•Noise reduction – no metal-to-metal contact; elas- tomer attenuates structure-borne noise and isolates vibration from components that would act as noise generators.

•Attachment – fi ts many standard SAE fl ywheels.

•Design fl exibility – standard rubber molds are used to produce each different size coupling shown in this catalog. Often it is necessary to change metal components for custom applications. This is common.

•Systems Engineering – LORD has in-house computer capabilities for multi-mass torsional analysis to assist in proper coupling selection.
