Geometrical Analysis of the Worm-Spiral Wheel Frontal Gear

摘要

The worm-spiral wheel frontal gear, known as Helicon gear is a constructive variant of the worm gearing. The advantage of these construction is a reduced overall size in the plane of spiral wheel, regarding the usually worm gearing. In this paper is presented the geometrical modeling of this gearing type in order to define the constructive elements of this. In the proposed modeling is accepted that the worm is an Archimede's worm, due of technological considerations.
