ABSTRACT / САЖЕТАК:

This study investigates the application of experimental design methods in optimizing the efficiency of a single-stage worm gearbox, with the CCD method being used to achieve maximum efficiency. The experiments were conducted on the AT200 device, considering rotational speed, lubricant type (VG220) and experiment duration as key factors. The optimization of efficiency was performed using the CCD method, and the results were analyzed through ANOVA. The findings indicate that rotational speed is a more influential factor compared to operating time, with the highest efficiency values recorded at the maximum rotational speed (≈1603.5 min⁻¹) and an operating time of 10 minutes. Mathematical models were developed with a 95% confidence level, enabling the prediction of efficiency based on the examined factors.
