The paper proposes a new method for calculating the service life, wear and contact pressures of metal-polymer gear drives with a correction profile. The effects of height and angular modification in a gear drive made of dispersive glass fibre-reinforced polyamide and steel on its contact and tribocontact parameters are determined. A numerical solution obtained for the gear with height correction has shown that the life of such gear is the longest when the profile correction coefficients 1 2 x = −x = 0.1. It has been found that the service life of the gear with angular correction is shorter than that of the gear with correction height. The effects of gear tooth height and angular correction on maximum contact pressures and pinion wear are examined and determined.
