Coupling Design
CouplingDesign Elastomeric Pre-compression Type
    Saga is a general purpose, torsionally soft coupling with high tolerance to all forms of misalignment. The design features hexagonal or octagonal rubber donut-shaped elements with metal inserts positioned at each apex during the vulcanization process. These metal inserts carry actual bolts which fix the element to tines on cast, cylindrical hubs. Embedded inserts also have tines which connect with mating surfaces on hubs so that axial bolts can be easily torqued during assembly without twisting the rubber beyond the limits of its elasticity. The rubber between each apex is precompressed, so it is much more durable to the stresses arising from the various forms of misalignment and torsional vibrations.

    While the Saga coupling is normally associated with shaft-to-shaft applications, adaptations for flange and flywheel mountings can be made. In addition, a floating shaft version for use in lieu of a universal joint drive shaft with separate torsional coupling is available. Its elements can also be stacked in series for use in applications with extreme transient or permanent parallel misalignment, or where torsional dynamics demand an extremely soft element for proper damping and/or vibratory decoupling. The rubber’s stiffness of 60 as measured against Shore A by durometer, covers the majority of such situations.
Features
Features
  • No end thrust in misalignment position
  • Absorbs misalignment and shock
  • No axial reaction force to damage or accelerate wear in system bearings
  • Accepts constant angular misalignment of up to 3°
  • Parallel tolerance of 0.060 (1.5mm), while reaction force remains low
  • Lateral softness without complication, or sacrifice of performance or durability
  • Natural rubber can operate in temperatures from -60° to 200° F (-51° to 93° C)
Note
Notes
  • For applications requiring simultaneous angular and parallel misalignment, consult Lovejoy Engineering to ensure that heat generated from all three forms of stress do not exceed the coupling’s ability to dissipate heat.
  • For higher speeds, balancing may be necessary.
  • Standard bores available by 1/16 inch increments.
  • Some metric sizes also available as standard.
