The effect of S 0 type of addendum modification on sliding velocity of the involute spur gear has been studied. For the analysis four critical points such as Beginning of Engagement, Low Point of Single Tooth Contact, High Point of Single Tooth Contact and Disengagement point corresponding to pinion are considered. Length of approach and length of recess for modified gears are evaluated. Effects of addendum modification on contact fatigue life and wear prediction are discussed. Product of contact stress and sliding velocity ( σ h * V s ) at critical points for varied addendum modification factor X are evaluated, and its effect on sliding velocity has been analysed. Effect of change in value ( σ h * V s ) at critical points of contact for modified gear pair on Hertzian fatigue is discussed.
