Pre-Nitriding: A Means of Significantly Increasing Carburizing Throughput
Carburizing is a surface-hardening method that uses heated metal in a carbon-rich environment to increase carbon levels on the metal, via diffusion, for added...
Comparison of Tooth Interior Fatigue Fracture Load Capacity to Standardized Gear Failure Modes
Introduction
Gears are case hardened to produce residual stresses at the surface — improving wear resistance, bending fatigue, and contact fatigue strength. These beneficial compressive...
Turning to Rolling Bearings for Industrial Gearboxes
Rolling bearings play vital roles in supporting the shafts and gear wheels of industrial gearboxes and, often, several different bearing types will function in...
