Abstract

Results of bench tests of gearwheels from steels 18KhGN2МFB, 20KhN3МА and 20Kh2N4А are considered. The reasons of premature failure of gear wheels at the forced modes loading are established. Laws of formation of mechanical properties on thickness of the strengthened layer for conditions of bench tests and operation are established. Efficiency of application of a settlement method of an estimation of a resource of the gear wheels is shown. The method considers heterogeneity of an intense condition and mechanical characteristics of strengthened layers of teeth, in comparison with natural bench tests.

Keywords
