Lateral Vibrations Causes And Some Solutions (in Electric
Some case histories of lateral vibrations in drive trains are reviewed, and solutions to some observed problems are noted. Twin drives are sensitive to lateral vibrations, due to the nature of the forces causing relative motion of the drive piers. Misalignment of the gear and pinion can cause stress concentrations in the teeth in the gear-pinion mesh, leading to overloads, spalling.
Ground Building Plant Vibration Measurement
Narrow band frequency analysis of the vibration revealed two distinct and separate types of vibration – tonal vibration at 18.25 Hz (and harmonics) plus a regular “thump”. The source of the “thump” was traced to roller backlash caused by bearing wear at the transfer gear end of a particular mill.
