Изобретение относитс к способам непрерывно-последовательной индукционной закалки по замкнутому контуру рабочих поверхностей изделий, например, крупногабаритных опорных роликовых подшипников.The invention relates to continuous-induction hardening processes along a closed loop of the working surfaces of products, for example, large-sized roller bearing bearings.
Известен способ пепрерывно-последовательной индукционной закалки по замкнутому контуру рабочих поверхностей изделий, включающий нагрев с помощью индуктора, расположенного в диаметральной плоскости изделени , и охлаждение.There is a known method of continuous-continuous induction hardening along the closed contour of the working surfaces of products, including heating by means of an inductor located in the diametral plane of production, and cooling.
Однако такой способ не обеспечивает удовлетворительной эксплуатационной надежности издели , так как полоска отпуска, образующа с при завершении нагрева рабочей поверхности под закалку, при эксплуатации подшипника целиком попадает под вращающийс ролик, что приводит к ее усиленному износу.However, this method does not provide satisfactory operational reliability of the product, since the tempering strip, which is formed when the working surface is heated for quenching, during operation of the bearing completely falls under the rotating roller, which leads to its increased wear.
Цель описываемого способа - повышение эксплуатационной надежности изделий путем уменьшени износа полоски отпуска на рабочей поверхности.The purpose of the described method is to increase the operational reliability of products by reducing wear on the tempering strip on the working surface.
Дл этого по предлагаемому способу нагрев производ т индуктором, расположенным под углом 15-45° к диаметральной плоскости издели .For this, according to the proposed method, the heating is performed by an inductor located at an angle of 15-45 ° to the median plane of the product.
Описываемый способ включает непрерывнопоследовательный индукционный нагрев по замкнутому контуру рабочей поверхности издели , например беговой дорожки крупногабаритного опорного роликоподшипника, с номощью индуктора, расположенного под углом 15-45° к диаметральной плоскости издели ,The described method includes continuous sequential induction heating along the closed contour of the working surface of the product, for example a treadmill of a large-sized support roller bearing, with an inductor that is located at an angle of 15-45 ° to the diametral plane of the product,

Однако благодар расположению полоски под угломand cooling, for example, with compressed air, which ensures hardness over the entire treadmill, except for the tempering strip, where the hardness is lower. However, due to the position of the strip at an angle
к диаметральной плоскости при эксплуатации подщипника на нее приходитс менее 50% удельной нагрузки ролика (остальна часть нагрузки приходитс на нормально закаленную поверхность), что значительно снижаетat the diametral plane during the operation of the sub-liner, it accounts for less than 50% of the specific load of the roller (the rest of the load falls on a normally hardened surface), which significantly reduces

The machining cycle is shortened, the bearing adjustment during assembly is simplified, and local wear of the tempering plane during bearing operation is practically eliminated.
