Abstract
The cylindrical spur tractive gear of the electric locomotive has been conducted using the author’s method of the calculation of maximum contact pressures, teeth wear and durability at technological correction of engagement at changeable, in the result of teeth wear and conditions of their contact. The regularities of tribocontact pressures change in engagement has been established after reaching the permissible wear depending on the shift coefficients in the phases of double–single–double tooth engagement. Considerable decrease of maximum tribocontact pressures is observed in the result of teeth wear in the entry phase of double-tooth engagement in comparison with their initial values. Depending on the shift coefficients, maximum (permissible) wear of wheel teeth would arise in different contact points: at the entrance into single-tooth engagement in non-corrected gear and at the exit in the presence of correction. Gear durability has its optimum at [Formula: see text] = 0.1 which is 1.22 times larger than in the absence of engagement correction.
