Dynamic Loading of Spur Gears with Linear or Parabolic Tooth Profile Modifications

Abstract

A computer simulation was conducted to investigate the effects of both linear and parabolic tooth profile modification on the dynamic response of low-contact-ratio spur gears. The effect of the total amount of modification and the length of the modification zone were studied at various loads and speeds to find the optimal profile modification for minimal dynamic loading. Design charts consisting of normalized maximum dynamic load curves were generated for gear systems operated at various loads and with different tooth profile modification. An optimum profile modification can be determined from these design charts to minimize the dynamic loads of spur gear systems. Keywords: Spur gears, Gear teeth, Gear noise, Gearboxes, Dynamic load, Profile modification, Transmission error, Gear design.
