Abstract

1. Способ упрочнения рабочей поверхности зубьев, включающий в себя цементацию с последующей закалкой ТВЧ, отличающийся тем, что, с целью расширения технологических возможностей путем обработки зубчатых колес при одновременном повышении качества за счет снижения склонности к трещинообразованию, цементацию проводят на глубину h1, а последующую закалку ТВЧ - на глубину h2 с температурой t2, где ! 0,16m≤h1≤0,24m, ! h1<h2<0,7m, ! a Ac3<t2<Ac3 исх. ! Ac3 - температура закалки для цементованного слоя ! Ac3 исх. - температура закалки основного металла ! t2 - температура нагрева ТВЧ ! 0,7m; 0,16m; 0,24m - заданные величины. ! 2. Способ п.1, отличающийся тем, что закалка проводится с охлаждением зуба путем воздействия охлаждающего агента на поверхность, противоположную закаливаемой. 1. A method of hardening the working surface of the teeth, including carburizing followed by hardening with HFC, characterized in that, in order to expand technological capabilities by processing gear wheels while improving quality by reducing the tendency to cracking, carburizing is carried out to a depth of h1, and the subsequent HFC hardening - to a depth h2 with a temperature t2, where! 0.16m≤h1≤0.24m,! h1 <h2 <0.7m,! a Ac3 <t2 <Ac3 ref. ! Ac3 is the hardening temperature for the carburized layer! Ac3 ref. - hardening temperature of the base metal! t2 is the HDTV heating temperature! 0.7m; 0.16m; 0.24m - set values. ! 2. The method of claim 1, characterized in that the hardening is carried out with the cooling of the tooth by the action of a cooling agent on the surface opposite to the surface to be hardened.
