Torsional Couplings
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.

LF Series
- The LF Series coupling is designed with a unique and highly versatile elastomeric element. These can be easily integrated into a variety of coupling configurations to meet several application needs. LF Style elements are available in a variety of materials to match the necessary coupling dampening characteristics for tuning the systems critical speed away from the application operating speed.
The element can be connected axially to a flywheel adapter plate or flanged hub and radially to a cylindrical center hub using the appropriate bolts. Axial bolt styles include either socket head bolts with a special dry adhesive, or S-Style bolts, which are similar to dowel pins (seen picture below). The radial bolts are used to connect the element to the cylindrical hub. This unique design is remarkably simple, highly effective and gives the LF torsional coupling unmatched performance capabilities. The coupling selection should be verified with a Torsional Vibration Analysis (TVA) of the system.
