(FR) PROCÉDÉS POUR PRODUIRE UN PIGNON
(JA) 歯車の製造方法
Abstract: front page image
(EN)A raw material which has undergone heating to the transformation point A3 or higher or remains unheated, depending on the steel components, is subjected to forging in the temperature range of 350-600°C. Alternatively, a forged intermediate obtained by hot forging or cold forging depending on the steel components is subjected to the same forging in the temperature range of 350-600°C.
(FR)Une matière brute qui, selon les composants de l'acier, a subi une chauffe au moins jusqu'au point de transformation A3, ou qui n'a pas encore été chauffée, est soumise à forgeage dans une plage de température de 350-600°C. Selon un autre mode de réalisation, un intermédiaire forgé obtenu par forgeage à chaud ou par forgeage à froid selon les composants de l'acier, est soumis au même forgeage dans la plage de températures de 350-600°C.
(JA) 鋼成分に応じて、A3変態点以上に加熱した素材又は加熱しないそのままの素材に、350~600℃の温度域で鍛造加工を施す。また、鋼成分に応じて、熱間鍛造又は冷間鍛造して得られた中間鍛造品に、350~600℃の温度域における同様の鍛造加工を施す。
