Lateral vibrations, causes and some solutions (in electric drive trains)

Abstract

Some case histories of lateral vibrations in drive trains are reviewed, and solutions to some observed problems are noted. Twin drives are more 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, harmonic wear and torque oscillations in the drive train.<>
