The ring-type coupling line has been developed to overcome numerous torsional problems associated with vehicular and industrial driveline systems. The result is increased equipment life by protecting against torsional vibration, shock and misalignment. Significant benefits are:
  • Misalignment Accommodation: elastomeric flexibility allows for large angular misalignment. For permissible misalignments, including axial and radial, see Table 1.
  • Vibration Isolation: low torsional spring rate is

General Description

N/A Dynaflex LCR Coupling capacity is rated from 4 to 135 hp at 2000 rpm. These easily installed couplings reduce noise transmission and increase bearing and driveline life through:

  • Greater misalignment accommodation.
  • Isolation of low frequency disturbances.
  • Isolation of torsional shock.

Single coupling arrangement consists of two shafts jointed by a single coupling for maximum economy.
Double coupling/series arrangement uses two couplings separated by a floating shaft. This provides same torque capacity as single hub arrangement, with twice the permissible angular misalignment and half the torsional stiffness. Superior to single coupling for control of torsional vibration.

Note

N/A Torque Requirements: Torque (lbs.-in.) = 63025 x hp/rpm
