Parameterized Model of Double-Roller Hourglass Worm Based on Pro/E Secondary Development Technology

According to the spatial meshing theory, the relative coordinate systems of non-backlash double-roller enveloping hourglass worm is established, the helix line and tooth surface equation are deduced. According to worm helix line equation, generating model with Pro/E, parametric modeling by Pro/Toolkit which is the secondary development tool belongs to Pro/E, programming relevant software.
