Description

Поверхностный нагрев валов под закалку уже известен. Известен далее, в частности в практике электросварки, прием электрического поверхностного нагрева изделий между роликовыми электрода.ми переменной пол рности.The surface heating of shafts for quenching is already known. It is known further, in particular in the practice of electric welding, the reception of electric surface heating of products between roller electrodes of variable polarity.

Использование этого приема дл  поверхностного нагрева валов под закалку и составл ет сущность насто щего изобретени .The use of this technique for the surface heating of shafts for quenching is the essence of the present invention.

В данном случае с целью нагрева вала под закалку производ т вращение его .между несколькими парами электродов.In this case, in order to heat the shaft for quenching, it is rotated between several pairs of electrodes.

Ограничение глубины нагрева достигаетс  здесь тем, что электроды поочередно присоединены к разным полосам или фазам источника электрического тока и таким образом замыкание тока происходит только в поверхностных зонах вала.The limitation of the heating depth is achieved here by the fact that the electrodes are alternately connected to different bands or phases of the source of electrical current and thus the current is only closed in the surface areas of the shaft.

Самые электроды могут быть выполнены в виде роликов или скольз щих контактов. Способ, согласно насто щему изобретению, иллюстрируетс  фиг. 1 и 2 чертежа.The electrodes themselves can be made in the form of rollers or sliding contacts. The method according to the present invention is illustrated in FIG. 1 and 2 of the drawing.

На фиг. 1 дан разрез устройства дл  выполнени  предложенного способа , а на фиг. 2-частичный разрез приспособлени  по оси одного из электродов.FIG. 1 shows a section through a device for carrying out the proposed method, and FIG. 2-partial section of the device along the axis of one of the electrodes.

Электроды В устанавливаютс  в разнимающейс  на две части державке С. Ширина нагреваемого участка определ етс  длиной соприкосновени  между валом и электродами, выполненными в виде роликов или скольз щих контактов, т. е. шириной электродов. Дл  облегчени  прижати  электродов к нагревае.мой поверхности служат пружины D.The electrodes B are mounted in a two-part holder C. The width of the heated portion is determined by the length of contact between the shaft and the electrodes made in the form of rollers or sliding contacts, i.e. the width of the electrodes. To make it easier to press the electrodes to the heating surface. Springs D are used.

Пос.1е нагрева поверхностного сло  вала до температуры несколько выше критической точки данной стали , ток выключаетс  и производитс  закалка поверхностного сло . В зависимости от свойств закаливаемой стали эта закалка .может быть произведена за счет отвода тепла в массу или путем охлаждени  воздухом или жидкостью (вода, масло).When the surface layer is heated to a temperature slightly above the critical point of this steel, the current is turned off and the surface layer is quenched. Depending on the properties of hardened steel, this quenching may be carried out by heat removal to the mass or by cooling with air or liquid (water, oil).

Предмет изобретени .The subject matter of the invention.

Способ поверхностного нагрева валов под закалку с применением известного приема электрического поверхностного нагрева между роликовыми электродами переменной пол рности , отличающийс  тем, что, с целью равномерности нагрева вал враи1.ают между несколькими парами электродов , выполненных в виде роликов или скольз щих контактов и npiicoединенных к разным полюсам или фазам источника электрического токаA method of superficial heating of shafts for quenching using a known reception of electrical superficial heating between roller electrodes of variable polarity, characterized in that, in order to uniformly heat the shaft, they are rotated between several pairs of electrodes made in the form of rollers or sliding contacts and connected to different poles or phases of an electrical current source
