Keep downsized engines from vibrating apart. (using couplings to correct torsional vibrations) (Managers Digest)

From: Construction Equipment | Date: July 15, 1993 | Copyright information

The low mass of small diesel engines reduces a driving system's natural frequency, thus bringing the driving system's vibration frequency closer to that of the driven system. When this happens, the system resonates and amplifies the vibrations to a level which can damage crankshafts, spline shafts, bearings, couplings, gears and seals in driven systems. To solve this problem, a complete torsional vibration review of the system is needed to select the right coupling that will tune the system's natural frequency out of resonance with torsional vibrations.

Selecting the right coupling can ...
