1 Prolonged exposure to temperatures in the 0 ºF range and below produces a significantly reduced slip torque prior to driveline warm-up. This condition may result in the coupling's inability to transmit adequate drive torque for applications experiencing unusual cold temperature related parasitic loading.
2 Prolonged exposure to temperatures in the 0 ºF range and below produces a significantly reduced slip torque prior to driveline warm-up. This condition may result in the coupling's inability to transmit adequate drive torque for applications experiencing unusual cold temperature related parasitic loading.

General Description
The Dynaflex coupling line has 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. Other significant features and benefits are:

  • Vibration Isolation: extremely low torsional spring rate is achieved with the Dynaflex coupling, using elastomer in shear. This allows for low system natural frequencies and isolation of first mode driveline disturbances.

  • Damping at Resonance: the elastomer used in LCD couplings effectively reduces vibration at resonance.

  • Shock Protection: torsional shock loads are attenuated by large shear deflection 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 flexibility allows for angular, parallel and axial misalignment.

  • Long Service Life: Lord Dynaflex couplings have proven themselves under demanding and rugged service conditions.

  • Maintenance Free: elastomer flexibility accommodates all motion without wear, eliminates the need for lubrication.

  • Noise Reduction: no metal-to-metal contact; elastomer attenuates structure-borne noise and isolates vibration from components that would act as noise generators.

  • Attachment: fits many standard SAE flywheels.

  • Design Flexibility: 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.
