Nevertheless, to have this characteristic, the axes of planar involute gear pairs must be parallel. Philips proposed a new spatial involute gear in 2000, based on the idea of a slip track, which can be thought of as a spatial involute curve. Philips designed general spatial involute gears that can be used in skew-axis transmission applications. However, he defined the spatial involute gears based on geometric c

Abstract:

A study into the effects of addendum modification on root stress in involute spur gears with various pressure angles are presented in this project work. The range of addendum modification co-efficient is taken from negative value to positive value through zero by considering both the upper limit(peaking limit) and the lower limit (undercutting limit). The root stress factor is found out for various loading positions. The variation of root stress factor with addendum modification co-efficient is shown when only the driving gear is modified.

By applying the mismatch of pinion-gear tooth surfaces, the tooth contact becomes a point contact instead of a line contact. The bearing contact is located at the middle region of the gear tooth surfaces and thus edge contact can be avoided. Unlike the generation of conventional involute helical gears, two imaginary rack cutters, instead of one, are applied for the ge
