Spur Gear Design With an S-shaped Transition Curve Application Using MATHEMATICA and CAD Tools

Abstract

The aim of this paper is to introduce the application of an S-shaped transition curve in designing and generating a spur gear. In engineering field, the spur gear usually designed by using an involute curve where this curve needs to use a tracing point method to obtain a curve while an S-shaped curve can obtain a curve directly. The comparative study between an S-shaped method and direct method in Computer Aided Design (CAD) tool also covered.
