TLDR
In this paper, the effects of linear tip profile modification on tooth root and tooth flank stress of involute spur gears were investigated and the amount of required tip relief profile modification was determined depending on the extent of tooth elastic deformation that needs to be compensated.Abstract:
This paper deals with the effects of linear tip profile modification on tooth root and tooth flank stress of involute spur gears. The increase in tooth flank stress due to tip profile modification is potentially hazardous due to increased risk of micro pitting initiation. The amount of required tip relief profile modification depends on the amount of tooth elastic deformation that needs to be compensated. In order to study the effects of linear tip profile modification on gear stress, two matching finite element models of involute spur gear pairs have been created, and tip relief profile modification has been applied to one pair. Tooth root and tooth flank stresses for both gear pairs have been compared in order to establish the effect of tip relief profile modification on gear stress.read more
