The paper presents the results of research undertaken to determine maximum contact pressures, wear and life of conical gears, taking account gear technological correction, tooth engagement and wear-generated changes in cur-vature of their involute profile. The calculations were made for a reduced cylindrical gear using a method developed by authors. The effect of applied conditions of tooth engagement in the frontal and internal sections of cylindrical gear ring is shown graphically. The initial maximum contact pressures will be higher in the internal section and the highest at the entry of single tooth engagement; the increasing of correcting coefficients will cause the fall of contact and tribocontact pressures; the optimum values of correction coefficients, at which the durability of the gear will be the highest were obtained.
