Theoretical and experimental investigations about flank breakage in bevel gears

Markus Klein, Bernd‐Robert Höhn, Klaus Michaelis, Rainer Annast

A failure mode called “flank breakage” is increasingly observed in cylindrical and bevel gears. Up to now, there was no calculation method available to determine the load‐carrying…

Pitting load carrying capacity under increased thermal conditions

Bernd‐Robert Höhn, Klaus Michaelis, Hans‐Philipp Otto

The purpose of this paper is to make an attempt to evaluate the pitting load carrying capacity under increased thermal conditions. This is the basis for an estimated lifetime…

Rolling‐sliding, scuffing and tribocorrosion behaviour of PVD multilayer coatings for gears application

Raquel Bayón, Cristina Zubizarreta, Roman Nevshupa, Juan Carlos Rodriguez, Xana Fernández, Unai Ruiz de Gopegui, Amaya Igartua

The aim of this work is the study the tribological behaviour and tribocorrosion resistance of newly developed multilayer PVD coatings Cr/CrN and CrN/ZrCN applied on nitrided F1272…

Influence of tooth profile on gear power loss

Luis Magalhaes, Ramiro Martins, Cristiano Locateli, Jorge Seabra

The purpose of this paper is to develop innovative geometry for gears aiming low power loss and easy manufacturing.

Evolution of tooth flank roughness during gear micropitting tests

Ramiro Martins, Cristiano Locatelli, Jorge Seabra

The purpose of this paper is to get a better understanding of roughness evolution and micropitting initiation on the tooth flank, as well as the evolution of surface topography…

Influence factors on gearbox power loss

Klaus Michaelis, Bernd‐Robert Höhn, Michael Hinterstoißer

Besides other approaches, fuel savings in automotive applications and energy savings, in general, also require high‐efficiency gearboxes. Different approaches are shown regarding…
