Parameterized Modeling of Involute Helical Gear by UG Based on Symmetric Equation

Article Preview

Abstract:

Swept method is a commonly used parametric modeling method for helical gears. For the problem of tooth profiles distortion and parameters loss in parametric design, the symmetric equations that used to establish involutes and dedendum transition curves are proposed. The boundaries between teeth and the starting and ending angles of tooth profile curve are precisely calculated. Feature-based swept methods are applied as solutions. Instance modeling results demonstrate the accuracy of the methods and also reflect their preciseness and convenience.
