NOTES: Red figures are metric reference.
LORD does not supply hubs. LORD supplies ring elements only.

Torque Requirements:

Torque (lb - in) = 63025 x hp
                               rpm

NOTE - * - See detail drawings by part number for tolerances.

 

***Notes only apply if called out in table***

NOTES

  1. Torque ratings as listed are maximum steady torques per application requirements. For general applications, dynamic torques of +/-35%of the coupling rate torques can be applied to the listed torque ratings. Shock (e.g. , start-up torque, etc.) of up to 200% rated torque are generally acceptable.
  2. Does not include bolts or flanges

 

 

 

Features and Benefits

  • Misalignment Accomodation - Elastomeric flexibility allows for larger angular misalignment. For permissible misalignments, including axial and radial, Refer to Table 1
  • Vibration Isolation - Low torsional spring rate is achieved with the elastomeric ring-type coupling using rubber in compression.This allows for low system natural frequencies and isolation of first mode driveline disturbances in most driveline systems.
  • Shock Protection - Isolates torsional shock, prevents backlash and protects system components, including bearings, from fatigue failure.
  • Long Service Life - Dynaflex LCR Series Couplings have proven themselves under demanding service conditions.
  • Maintenance Free - Elastomer flexibility accomodates 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.
  • Systems Engineering - LORD has in-house computer capabilities for multi-torsional analysis to assist in proper coupling selection.

NOTE - * See detail drawings by part number for tolerances.
