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.
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
- 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.
- Does not include bolts or flanges
