Abstract

The electric motor is always part of the agricultural production system, in particular the animal production system. Its purpose is to equip a technological object with energy to ensure the functioning of the production process. The weak link of electric motors used in animal production is the bearing assemblies due to their wear in the corrosive environment of the premises used in this industry. The aim of the work was to assess the effect of inhibitory protection on the reliability of the bearing assemblies of electric motors for the conditions of their operation in animal husbandry. A theoretical resource distribution of bearing assemblies was chosen, approximated by the three-parameter Weibull distribution. For two groups of bearing assemblies, with and without inhibitory protection, bench tests were carried out to simulate the conditions of animal husbandry. The distributions of the initial wear rate of bearings and the difference between the limiting and initial wear rates were obtained. Using the theoretical distribution, the parameters of Weibull distribution were established. Their analysis showed that the use of the inhibitor “Prana” increases the durability of bearings by 15%, which indicates the advisability of using this protection in animal husbandry conditions.
