description: This work is devoted to the choice of the chemical-thermal treatment mode, which provides the best wear resistance and contact endurance of gears. Tasks that were solved in the course of the study: 1. Comparative metallographic analysis of the microstructure of samples after various modes of chemical-thermal treatment. 2. Comparative analysis of the hardness of samples after various modes of chemical-thermal treatment. 3. Evaluation of the influence of the content of alloying elements on the hardness of the samples after the selected mode of chemical-thermal treatment. 4. Comparative evaluation of permissible contact stresses. According to the results of the study, for a pair of spur gears of a tractor gearbox, a chemical-thermal treatment mode was selected, consisting of preliminary normalization of the workpiece and subsequent carburizing, hardening and tempering. Using this mode allows you to: â increase wear resistance; â increase the allowable contact stress by increasing the long-term limit of contact endurance.
