Optical profilometry will become an important tool for predicting gear performance with more research and development of an objective lens to fit into tooth spaces....

A Comparison of Surface Roughness Measurement Methods for Gear Tooth Working Surfaces

Posted by Mark Michaud on Freitag, Oktober 25th, 2019 in

Surface roughness is a critical parameter for gears operating under a variety of conditions. It directly influences friction and contact temperature, and therefore has an impact on various failure modes such as macropitting, micropitting and scuffing...

Gear Corrosion During the Manufacturing Process

Posted by Danny Estrada on Dienstag, November 19th, 2013 in

No matter how well gears are designed and manufactured, gear corrosion can occur that may easily result in catastrophic failure. Since corrosion is sporadic and a rare event and often difficult to observe in the root fillet region or in finely pitche...

The Effect of Superfinishing on Gear Micropitting II

The Effect of Superfinishing on Gear Micropitting, Part II

Posted by Danny Estrada on Dienstag, November 19th, 2013 in

It should be noted from the outset that the data presented in Part I and Part II of this paper was generated by independent laboratories. Superfinishing of the gears was the authors’ sole contribution to these studies....

A Novel Approach to the Refurbishment of Wind Turbine Gears

Posted by Danny Estrada on Mittwoch, November 13th, 2013 in

Multi-megawatt wind turbine gearboxes operate under demanding environmental conditions including considerable variation in temperature, wind speed, and air quality....

The Impact of Surface Condition and Lubricant on Gear Tooth Friction

Posted by Christina Michaud on Donnerstag, November 6th, 2014 in

Frictional losses in gear boxes are of significant interest to gear box designers as these losses transform into heat. The direct result is a reduction in the fuel efficiency of the vehicle involved....
