In this paper, an approach for mesh generation of gear drives at any meshing position is
presented and an automatic modeling program for tooth mesh analysis is developed. Based …

Two versions of face-gear drive geometry with a helical pinion are considered. One version
is based on a screw involute helicoid. The second version is a new geometry developed as …

Contact fatigue, one of the main failure modes of gear tooth flanks, is caused by repeated
compression and shear stress cycles. In this study, the surface and subsurface stresses of …

In practical use, most gears have an involute shape of tooth flanks. However, external
involute gears have some drawbacks, such as unfavourable kinematic conditions at the …

The main defects of misaligned helical gear drives with parallel axes are: edge contact,
noise, and not favorable conditions of bearing contact. One of the greatest concern of …

Gears are one of the important components in mechanical products, and their fatigue
reliability determines the safety performance of mechanical products. In this paper, the …
