Abstract
A technique for the design calculations of the local strength, wear, and durability of tractive cylindrical double gear of VL-10 locomotive with angular tooth correction has been suggested. The technique allows for realistic engagement conditions (parity and wear-induced changes in the tooth profile curvature). The regularities of the effect that structural (angular engagement correction) and operational (linear tooth wear) factors have on these parameters for triple–double–triple tooth engagement in this gear have been revealed. It has been established that, when considering tooth correction, there are certain optimum displacement coefficients that maximize the durability compared to the uncorrected gear. It has been shown that, if one allows for changes in the tooth-profile due to wear are allowed for, the actual durability and bearing capacity of the gear is higher. The results have been presented graphically in order to help establish regularities of the effect of engagement conditions on the tribotechnical characteristics.
