An approach for forming spur gear tooth profile

Abstract EN

Due to high working speed requirement in industry of rotating components, gear design development become quite noticeable and rapid in the vicinity of engineering parameters which become to have a large effect on its performance.

In this work the spur gear of straight tooth is chosen because of its wide usage in industry, also an equation for joining the involute profile and fillet curve is generated.

Variation effect on the shape of tooth profile forming is studied.

A suggested method for generating tooth profile is obtained and a computer program is written for drawing the involutes and trochoid curves.

The results obtained from the new method are the true continuous involute and trochoid curves in comparison with those obtained from Mechanical Desk software which are approximated curves fitted results.
