Calculation methods for predicting the service life of metal-polymer gears with height correction are proposed. Two methods for gear service life estimation are presented: a simplified method that assumes constant tooth interaction conditions and an improved method that takes into account wear-induced changes in tooth interaction conditions. Spur cylindrical gears with a steel gear and a pinion made of polyamide composite reinforced with carbon and glass fibres are studied. The effect of height correction on the service life of the gears is examined, considering the type of tooth engagement. It is established that with the improved method the service life of the gear is by up to 1.3 times longer than that calculated by the simplified method at optimal height correction coefficients. Optimal service life of the gear is achieved when the correction coefficients are x1 = – x2 = 0.1. The effect of the coefficient of friction on gear service life is investigated. It is found that the service life of the gear with a carbon fibre-reinforced pinion is by 8.1...9.3 times longer than that of the gear with a glass fibre-reinforced pinion.
