In order to study contact characteristics of planar double-enveloping hourglass worm gears, it deduced contact line formula based on the forming principle of worm and gear principle. It designed a worm parametric feature analysis software based on VC and Matlab software with the theory of model parameters and theoretical formulas. Software automatically forms generatrix contact line and worm contact line based on the model parameters, generating further graphics of three-dimensional mode, and exams the software by using proctical examples. The results contribute to quick analysis for the structure of planar double -enveloping hourglass worm gears and contact properties. It provides the basis for designing model structural parameters, quick ftx and optimization, which has certain practical opplication value.
