Изобретение относитс  к способам обработки изделий, работающих на статическое и ииклическое кручеиие.This invention relates to methods for treating products that work on static and dynamic torsion.

Иззестеи способ обработки изделий, включающий термомеханическую обработку и новерхиостиый иаклеп.Izzdestei is a method of processing products, including thermomechanical processing and a high-baked hackle.

Однако известпый способ не обеспечивает достаточно высокого значени  предела упругости и, соответствеиио, высокого значени  уровн  рабочих напр жений в изделии.However, the lime method does not provide a sufficiently high value of the elastic limit and, correspondingly, a high value of the level of operating stresses in the product.

Дл  повышени  конструктивной прочности изделий, работающих на кручение, нредлагаетс  способ, но которому после поверхностного наклепа производ т холодиую деформацию кручением.In order to increase the structural strength of torsion products, a method is proposed which, after surface work hardening, is produced by cold deformation by torsion.

Описываемый способ включает термомехаиическую обработку издели  (низко или высокотемпературную ) с использованием деформации кручением, финишную механическую обработку (чистовую шлифовку, хониигование и др.), поверхностный наклеп, например, путем обкатки роликами, обдувкой дробью и холодную деформацию кручеиие.м (заневоливание ), нричем направление деформации кручением (как гор чей, так и холодной) The described method includes thermomechanical treatment of the product (low or high temperature) using torsional deformation, finishing machining (fine grinding, honing, etc.), surface work hardening, for example, by rolling with rollers, blowing shot and cold deformation torsion.m (over-volo), the direction of torsional deformation (both hot and cold)

совпадает с направлением ириложеии  раоочих напр жений.coincides with the direction of irilodeia of the raw voltages.

Описываемый способ был проверен при обработке изделий из среднеуглеродистых легированных сталей, например стали 45 ХНМФА. При обработке изделий по описываемому способу предел пропорциональности был повышен до 160 кг/мм а предел усталости - до 125 кг/мм, значени  этих характеристик при обработке но известному способу соответственно 120 и 110 кг/с.м.The described method was tested when processing products from medium carbon alloyed steels, for example, steel 45 HNMFA. When processing products according to the described method, the proportionality limit was increased to 160 kg / mm and the fatigue limit - up to 125 kg / mm, the values of these characteristics during processing by the known method, respectively, 120 and 110 kg / cm.

Благодар  повышению предела упругости и усталостной прочности применение опнсыпаемого способа позвол ет повыснть долго1юч пость т желонагруженпых деталей, i)a6oiaio щих на кручепие.Due to the increase in the elasticity and fatigue strength, the application of the supported method allows an increase in the longitude of the yellow loaded parts, i) a6oiaio for torsion.

Предмет изобретени Subject invention

Способ обработки изделий, включающий термомеханическую обработку и поверхностный наклеп, отличающийс  тем, что, с целью новыщени  конструктивной прочности изделнй, работающих па кручение, нослс иоверхностного паклена нроизвод т холодную деформацию кручением.A method of processing products, including thermomechanical processing and surface hardening, characterized in that, in order to increase the structural strength of parts working on torsion, it was necessary to produce cold deformation by torsion on the surface.
