Influence of linear profile modification and loading conditions on the dynamic tooth load and stress of high contact ratio gears [PDF]
A computer simulation for the dynamic response of high-contact-ratio spur gear transmissions is presented. High contact ratio gears have the potential to produce lower dynamic tooth loads and minimum root stress but they can be sensitive to tooth profile
