Resources

Lovejoy offers a wide range of torsional couplings engineered to solve torsional vibration problems found in diesel engine driven equipment and other applications where torsional vibrations are prevalent. These include all internal combustion engines, reciprocating pumps and compressors, as well as variable frequency drives (VFD).

Lovejoy torsional coupling are designed to dampen torsional vibrations and tune, or adjust the system’s critical speeds away from the application’s operating range. With the proper information, Lovejoy engineers can perform a Torsional Vibration Analysis or TVA for your application to assist in the selection of a torsional coupling.
