Induction Hardening of Gears and Gear-Like Components
2014AbstractInduction hardening is a prominent method in the gear manufacturing industry due to its ability of selectively hardening portions of a gear such as the flanks, roots, and/or tips of teeth with desired hardness, wearing resistance, and contact fatigue strength without affecting the metallurgy of the core.

Abstract Through-hardening heat treatment is generally used for gears that do not require high surface hardness. In through hardening, gears are first heated to a required temperature and then cooled either in the furnace or quenched in air, gas, or liquid.

Abstract Some gears may need to be hardened only at the surface without altering the chemical composition of the surface layers. Induction hardening may be a suitable processing choice in these cases. This chapter provides information on the wide variety of materials that can be induction hardened and on process details involved in ...

Carburizing and Hardening Gears
2000Abstract The primary objective of carburizing and hardening gears is to secure a hard case and a relatively soft but tough core. For this process, low-carbon steels (up to a maximum of approximately 0.30% carbon), either with or without alloying elements (nickel, chromium, manganese, molybdenum), normally are used. The processes involved

Finish Cutting of Case-Hardened Gears
CIRP Annals, 1986The requirements for finish machining of case hardened gears are described; also the process and the range of its application. The machine tool and its specific equipment for the hard cutting process are discussed. The tools and their properties are demonstrated especially those of the cutting edges.

Small gear hardening with a CO2 laser
ICALEO '88: Proceedings of the Laser Materials Processing Conference, 1988The CO2 laser is a unique light source whose properties make it a powerful tool for materials processing. The laser’s ability to provide a collimated beam of coherent light allows light energy to be directed over distances without spreading out. In that this energy is in the form of light it propagates through air, no force is exerted on the workpiece,

The Conjugation of the Hardened and Grinded Worm Gear
Advanced Materials Research, 2010Research of the new kind of meshing is an important research direction of mechanics and manufacture. At present, we have only few methods. Such as the Oliver first method, the Oliver second method and the F. Litven’s method. This paper presents a new kind of conjugate method. The new method is of great significant both in theory and in practice.

THE NEED OF GRINDING CARBURIZED AND HARDENED GEARS
SAE Technical Paper Series, 1924<div class="htmlview paragraph">Graphical demonstration is given of the desirability of grinding gears that are made of carburized material. The warping of carburized gears is shown to be due to the shrinking of the carburized metal. The teeth cut on the regular commercial type of hobbing machine vary in form; those cut on a simplified hobbing ...
