Abstract Purpose: Investigations include results of research opportunities of improving the quality of
open toothed wheels using advanced technologies of surface by ion nitriding in hydrogensaturating
media and subsequent heat treatment with the creation of the material in the
surface layer of optimal residual compressive stresses.
Design/methodology/approach: Researches on high-cycle bending fatigue were
performed on the smooth cylindrical samples with a diameter of 5 mm using IMA-5 engine
in pure bending with rotation (50 Hz) in the 3% NaCl solution and midair.
Findings: The analysis of the operating conditions and the stress-strain state of open
toothed weels showed that different portions of the surface of the teeth take different in
size and type of stress. The most dangerous areas of the surface have a leg and depression
between the teeth.
Practical implications: Experience of operating gears indicates that the vast majority of
failing of open gears occurs as a result of breakage of teeth from bending. Currently, there
are many ways to improve the wear resistance and durability of the gears, but the problem
is not solved until the end and it is urgent.
Originality/value: In order to improving the quality of open toothed wheels by hardening
the surface of the toothed wheels and especially in hazardous areas due to the deposition of
hardening coatings with a gradient structure in depth, authors create a surface layer of residual
compressive stress with optimal value and strengthening the core of the toothed wheel.
