Parameter study on the calculated risk of tooth flank fracture of case hardened gears
Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2017 Due to better material qualities, new surface finishing methods and better heat-treatment process reliability, flank surface damages, such as pitting or micropitting, can be prevented in a reliable manner.

Common problems and pitfalls in gear design [PDF]
There are several pitfalls and problems associated with the successful design of a new gear transmission. A new design will require the knowledge and experience of several technical areas of engineering.

Bulletin of JSME, 1985 Gears made of four kinds of low-alloyed steels with different hardenabilities were through-hardened in a cooling oil to investigate an influence of hardenability on gear distortions which is considered as a criterion for thickness of hardened layer. From the experiment, the gear distortions caused by the hardening are found to be related not only with ...

Layer Approach to Model Fatigue Strength of Surface-Hardened Components
MetalsThis paper deals with a surface-hardened forged steel that is commonly used for powertrain components like gears, axles or crankshafts. In order to increase static and fatigue strength and to minimise wear, surface treatments like induction hardening ...

Effect of two synthetic lubricants on life of AISI 9310 spur gears [PDF]
Spur-gear fatigue tests were conducted with two lubricants using a single lot of consumable-electrode vacuum-melted (CVM) AISI 9310 spur gears. The gears were case carburized and hardened to Rockwell C60. The gear pitch diameter was 8.89 cm.

Plastic deformation mechanism of hypoid gears
Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2017 Hypoid gears are used as the final reduction gear of vehicles to transmit and change direction torque. Plastic deformation of a hypoid gear tooth flank occurs when a load exceeding the yield stress acts on the tooth surface.

An update on the life analysis of spur gears [PDF]
, 1983 An analytical method for predicting surface fatigue life of gears was presented. General statistical methods were outlined, showing the application of the general methods to a simple gear mesh.
