| Sumario: | As a result of the analysis of statistics on the main failures of the turbocharger of tractor engines in agricultural production, it can be concluded that it is the condition of its bearing node, in the first place, determines the performance of the entire turbocharger. This ultimately affects the duration of the turbocharger rotor after the engine stops. The article considers the method of determining the rotation time of the turbocharger rotor by inertia depending on the following factors: the time of the pressure drop in the turbocharger grease system, the gap in the turbocharger bearing node, the frequency of rotation of the rotor before the engine stops. The results of experimental studies on the timing of the turbocharger rotor rotation after the engine stop for the regular mode of greasing the bearing node and when using an individual lubricant system are presented. Based on the experimental values obtained, it is concluded that the main indicator of the performance of the turbocharger is the duration of rotation of its rotor after the engine stops and the application of the individual system of lubrication of the bearing node of the turbocharger reduces the cost of bearing resource and increases the resource of the entire turbocharger of agricultural machinery engines at least twice. |
