Description
Извест.ный снособ непрерывно-носледовательной поверхностной закалки .крунномодульных шестерен, включающий индукционный нагрев зубьев через впадину с номощью индуктора , совершающего возвратно-лостунательное движение, «аиример, вверх-вниз, и охлаждение сжатым воздухом, при котором закалку производ т при движении индуктора в одном направлении, например вверх, приводит к односторонней деформации (тарелообразности ) шестерен.Known methods of continuous continuous surface hardening of round-modular gears, including induction heating of the teeth through a hollow with the help of an inductor performing a back-to-down motion, and cooling with compressed air, at which hardening is performed when the inductor moves one direction, for example upwards, leads to one-sided deformation (plateau) of the gears.
С целью уменьшени деформации шестерен но предлагаемому способу продесс закалки производ т при движении индуктора и в обратном направлении.In order to reduce the deformation of the gears, but the proposed method, the hardening process is carried out with the inductor moving and in the opposite direction.
Закалку производ т с .помощью .индуктора, снабженного двум спрейерами, расположенными по разные стороны от индуктора и работающими попере.мбнно.Quenching is carried out using an inductor, equipped with two sprayers located on opposite sides of the inductor and working across the hall.
Описываемый способ включает установку шестерни на столе закалочного статака в горизонтальном положенИ|И, включение индукционного нагрева, кратковременную выдержку, нагрев первой впадины при движении индуктора вверх, охлаждение нагретых участков сжатым воздухом с помощью нижнего закалочного спрейера, поворот шестерни, при котором против индуктора оказываетс треть по счету впадйна, нагрев при движении индуктора вниз, охлаждение с помощью верхнего закалочного спрейера и поворот шестерни, при котором против индуктора оказываетс п та по счету впадина. Затем цикл обработки повтор ют: закалку поверхностей впадин четныхThe described method includes installing a gear on a hardening table in a horizontal position and turning on induction heating, brief exposure, heating the first trough when the inductor moves up, cooling heated areas with compressed air using a lower quenching sprayer, turning the gear in which the third is opposite the count is hollow, heating when the inductor moves downwards, cooling with the help of an upper quenching sprayer and turning the gear, with which That account trough. The processing cycle is then repeated: quenching the surfaces of the troughs of even
зубьев производ т аналогично. Поскольку ход индуктора в обоих направлени х вл етс рабочим , сокращаетс продолжительность закалки шестерни ,и уменьшаетс односторонн деформаци (тарелообразность).The teeth are made similarly. Since the inductor stroke in both directions is operative, the duration of gear hardening is reduced, and one-sided deformation (flatness) is reduced.
Оиисываемый способ был проверен при закалке шестерен т-16 из стали 25ХНЗМФАР с помощью машинного генератора мощностью 200 кет частотой 8000 гц. В результате закалки на рабочей поверхности шестерен полученаThe test method was tested during the hardening of gears t-16 from steel 25HNZMFAR using a 200 kt machine generator with a frequency of 8000 Hz. As a result of quenching on the working surface of the gears obtained
твердость 47-52 ПКС .при м.шьи.мальной глубине закаленной зоны 1,5 мм.hardness 47-52 PKS. when the maximum depth of the hardened zone is 1.5 mm.
Благодар уменьшению односторонней деформации при закалке повышаетс выход годного при закалке круп юмодульных шестерен .Due to the reduction of one-sided deformation during quenching, the yield during hardening of the croup of gears increases.
