В статье рассмотрена методика выбора материала зубьев шестерен на основе износосостойкости. В ней также учитываются твердость, количество циклов нагружения, приводящих к разрушению деформированного слоя материала на поверхности трения, соотношение твердости материала шестерен и прочности абразивных частиц, находящихся в клиновидном зазоре зубьев. Установлены закономерности изменения скорости изнашивания и ресурса, открытых и закрытых зубчатых передач, с участием и без участия абразивных частиц в процессе изнашивания зубьев шестерен, в зависимости от модуля зацепления и вида упрочняющей обработки поверхности, при объемной закалке, закалке током высокой частоты и цементации.

Мақолада тишларнинг ейилиш бардошлиги асосида шестернялар учун материал танлаш услубияти кўриб чиқилган. Очиқ ва ёпиқ тишли узатмаларнинг ейилиш тезлиги ва ресурсининг ўзгариш қонуниятлари шестерня тишларининг ейилиш жараёнида абразив заррачаларнинг иштироки ва иштирокисиз, илашиш модули ва сиртга мустаҳкамловчи ишлов бериш тури, қаттиқлиги, ишқаланиш сирти материалининг деформацияланган қатлами бузилишига олиб келувчи юкланиш цикллари сони, тишларнинг понасимон тирқишида жойлашган абразив заррачалар мустаҳкамлиги, ҳажмий тоблашда, юқори частотали ток билан тоблашда ва цементациялашда илашиш модули ҳамда сиртга мустаҳкамловчи ишлов бериш турига боғлиқ ҳолда аниқланган.
This article reviews a method for selecting a gear material based on the wear resistance properties of teeth. The approach takes such properties as hardness, number of loading cycles leading the destruction a deformed layer of friction surface material and correlation of hardness of gear material and strength of abrasive particles in wedgeshaped gap of teeth, into account. The research has maintained principles of alteration of the wear rates and service life of open and closed gears, with and without abrasive particles in the process of gear teeth wear, depending on the meshing module and the type of hardening surface treatment, at volume hardening, hardening by current of high frequency and cementation.
