A Mathematical Model for Parametric Tooth Profile of Spur Gears

open access: yesMathematical Problems in Engineering, Volume 2020, Issue 1, 2020., 2020
Spur gears are widely used transmission components. In the traditional design process, the noninvolute part of the tooth profile curve is difficult to describe with mathematical equations. This article puts forward a new parametric modeling method, which can describe the modified involute part of spur gears and parameterize and optimize the transition ...
