Materials Matter: Comparing Surface Roughness Parameters

Posted by Danny Estrada on giovedì, Gennaio 5th, 2017 in

Effective gear design must account for a range of potential failure modes. As discussed in previous Materials Matter columns, gear failure modes can be fatigue-based and progressive (such as micropitting) or sudden (such as scuffing)....

Materials Matter: Lambda Ratio

Posted by Justin Michaud on venerdì, Ottobre 21st, 2016 in

The lambda ratio was originally developed to quantify the quality of lubricant operating regimes relative to bearing performance....

Materials Matter: Micropitting

Posted by Martin McCormick on sabato, Settembre 17th, 2016 in

Micropitting is a gear failure mode that typically occurs when higher contact stresses are applied to hardened gear teeth. Unlike most other failure modes, micropitting does not always proceed to component failure if left unaddressed....

Materials Matter: Scuffing

Posted by Martin McCormick on sabato, Settembre 17th, 2016 in

Gear meshing is one of the most complex areas of study in tribology. Meshing consists of both sliding and rolling motion and can be affected by a number of other operating parameters....

Materials Matter: Wind Turbine Gear Repair

Posted by Christina Michaud on martedì, Maggio 31st, 2016 in

Due to the large installed base of wind turbines, demand for gearbox repairs has risen steadily in recent years. Isotropic […]...

Materials Matter: Power Density and Isotropic Superfinishing

Posted by Martin McCormick on domenica, Aprile 17th, 2016 in

Power density, also described as load-carrying capacity, is simply the amount of load that can be safely transferred by a gear or other power transfer component without failure....

Materials Matter: Isotropic Superfinishing

Posted by Justin Michaud on mercoledì, Marzo 16th, 2016 in

Increasingly stringent operational requirements from customers coupled with enhanced global technical standards have heightened the focus of gear designers on a wide array of parameters that historically would have been of secondary consideration; on...
