Abstract
A computer program has been developed to design external spur gears having normal contact ratios (<2.0) and high contact ratios (≥ 22.0). This program has been used to study the effects of changes in some gear parameters on several performance factors of high-contact-ratio gears. The results are compared with those for the equivalent normal-contact-ratio gears.
The study shows that a high-contact-ratio gear obtained by increasing the addendum of an equivalent normal-contact-ratio gear will have lower bending and compressive stresses (favorable) and increased friction heat generation and flash temperatures (unfavorable).
