Gear tooth surface fatigue is one of the most common failure modes of gears. Surface fatigue
manifests on two principle phenomena, namely spalling and pitting. Spalls are localized …

This paper proposes an experimental methodology to characterize complex parts presenting
various gradients using aeronautical induction surface hardened spur gears. A 3D fatigue …

The article presents a comprehensive study on the tooth bending strength of spur gears with
a progressive curved path of contact, or so-called S-gears. Systematic gear meshing …

For increasing the load carrying capacity of geared power transmissions several tooth
designs alternative to the standard involute have been proposed. The use of non-involute …

The updated and improved second edition of Direct Gear Design details a nonstandard gear
design approach that makes it possible to significantly improve gear drive performance …

This research paper discusses a novel method to prevent the tooth failure in the spur gear
by introducing circular root filet instead of standard trochoidal root filet in the gear. In …

Optimising the hob used to manufacture gears is an attractive approach for minimizing the
gear tooth root stress. However, currently available approaches often require modifying the …

This paper examines the tooth failure in spur gears. Corrective measures are taken to avoid
tooth damage by introducing profile modification in root fillet. In general, spur gear with less …

An innovative approach to the design of the gear-tooth root-profile, and its effects on the
service life is reported in this paper. In comparison with the widely used trochoidal and the …

Circular fillet (CF) gears have been proven to possess a higher bending strength than their
standard trochoidal fillet (TF) counterparts. However, stronger nonstandard variants of the TF …
