Description

При известной поверхностной закалке токами высокой частоты шеек коленчатых валов или других деталей весьма трудно получить закаленный слой равной толщины по всей длине закаливаемого тела, так как нагревание поверхности зависит от условий отдачи тепла, за счет теплопроводности тела, по кра м в более значительной степени, чем в середине. Кроме того и распределение тока в индуктирующей катушке во многих случа х может обусловить неодинаковую толщину закаленного сло  2 подобно показанной на фиг. I чертежа схеме (заштрихован закаленный слой).With known surface hardening by high-frequency currents of the necks of crankshafts or other parts, it is very difficult to obtain a quenched layer of equal thickness along the entire length of the hardened body, since the surface heating depends on heat release conditions due to the body thermal conductivity in the middle. In addition, the current distribution in the inducing coil in many cases may result in unequal thickness of the hardened layer 2, like that shown in FIG. I drawing scheme (shaded hardened layer).

Насто щим изобретением поставлена цель достижени  равномерной по глубине закалки на издели х значительной длины и получение нужной глубины закалки, отвечающей услови м работы данной детали. Достигаетс  это за счет того, что внутренн   поверхность индуктирующей катушки 3, срсто п1,ей из одного или нескольких витков, выполн етс  вогнутой (фиг. 2).The present invention aims to achieve a uniform depth of quenching on products of considerable length and obtaining the desired quenching depth that meets the conditions of operation of the part. This is achieved due to the fact that the inner surface of the inducing coil 3, cpst p1, of one or several turns, is concave (Fig. 2).

Аналогичное решение дают и варианты , показанные на фиг. 3 и 4 чертежа , согласно которым примен етс  несплощна  катущка 3 с прорезами 4 (фиг. 3) или же состо ща  из витков с неодинаковой осевой щириной (фиг. 4). На чертеже цифрой 7 обозначено закаливаемое изделие, в частном случае шейка коленчатого вала.A similar solution is given by the variants shown in FIG. 3 and 4 of the drawing, according to which the non-squaring roller 3 is used with slots 4 (Fig. 3) or consisting of coils with unequal axial broadening (Fig. 4). In the drawing, numeral 7 denotes a hardenable product, in the particular case of the crankshaft journal.
