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

Posted by Mark Michaud on Friday, October 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...

Superfinishing and its Effect on Micropitting

Posted by Martin McCormick on Monday, April 13th, 2015 in

Micropitting is a prominent failure mechanism for both highly stressed case carburized gears and bearings that operate consistently in low speed, low load environments where boundary conditions predominate....
