Abstract

The purpose of the research is to study the grinding properties and mechanisms of 20CrMnTi steel gears machined by WD-201 microcrystal corundum grinding wheels. It conducted experimental study analysis on the integrity of grinding surfaces. Firstly, it analysed the trends in gradient change of carbon concentration in carburized layers of gear blanks on microhardness, retained austenite, and lath martensite. Secondly, it discussed the effect, and mechanisms, of transformation morphologies of different metallographic structures on residual stresses and their microhardness. In addition, the effects of grinding speed, radial feed, and axial feed rate on grinding temperature, microhardness, and depth of metamorphic layers were analysed. These provide experimental bases for the reasonable selection of gear grinding processes.
