摘要： A shot peening method for gears capable of hardening a gear without formation of projections on the tops of its teeth and gears having no projections and treated by this shot peening method are provided. After a preliminary shot has been performed to harden the top of a tooth of the gear by shooting only at the top of the tooth using an air nozzle, a bottom land shot is performed by shooting shots at a bottom land in a substantially perpendicular direction thereto with an air nozzle, whereby the gear is entirely hardened.

摘要： For easily producing a toothed material for high-strength gears etc. with a plastic working technique, deformation resistance occurring in plastic working is reduced and stable high precision plastic working is enabled at lower temperatures. One or more types of heat treatment selected from carburization, carbonitriding and nitriding and a hardening process are applied to an alloy steel material containing: iron as a main component; at least 1.0 to 4.5 wt % Si; 0.35 wt % or less C; and balance Fe and unavoidable impurities, whereby a rolling element is obtained which has a surface layer mainly composed of martensite containing no &agr;-Fe phase and of residual austenite and an inner structure cooled from an (&agr;+&ggr;)-Fe two phase region.
