    May 01,  · Induction hardening has been used for some years to harden the surface and improve the strength and service life of gears and other components. Many applications that employ induction hardening require a relatively long time to finish the hardening process and controlling the hardness of the surface layer and its depth often was a problem. surface-hardened gears (for example, carburized, nitrided, induction hardened, and flame hardened), pitting may occur on a much smaller scale, typically only 10 mm ( min.) deep. To the naked eye, the areas where micropitting has occurred appear frosted, and “frosting” is a popular term for micropitting.

    Machine elements considered in this book are those more commonly found in machines transmitting power by means of moving components, such as motors and egypharmed2018.com diagram given in Figure illustrates the range of machine elements involved in the design of a gear box for a single cylinder air compressor and comprises: shafts, bearings, gears.

Get this from a library. The surface fatigue life of contour induction hardened AISI gears. [Dennis P Townsend; Alan Turza; Mike Chaplin; United States. National Aeronautics and Space Administration.; U.S. Army Research Laboratory.]. The gears were case-carburized AISI steel spur gears.

Some gears were provided with the coating by magnetron sputtering. Lives were evaluated by accelerated life tests. For uncoated gears, all of 15 tests resulted in fatigue failure before completing million egypharmed2018.com by: Previous research provides qualitative evidence that an improved surface finish can increase the surface fatigue lives of gears.

To quantify the influence of surface roughness on life, a set of AISI steel gears was provided with a near-mirror finish by superfinishing. The surface fatigue life of contour induction hardened AISI gears.

May 19,  · Surface hardening techniques are widely used to improve the rolling contact fatigue resistance of materials. This study investigated the rolling contact fatigue (RCF) resistance of hardened, ground steel rods made from three different aircraft-quality alloy steels (AISIand ), and hardened using different techniques (atmosphere carburizing, vacuum carburizing, and induction.
