Abstract

The article considers the influence of nanoadditives on the performance characteristics of radial slide bearings. The samples of lubricants were prepared on the basis of mineral oil with additives of fullerene soot and a mixture of fullerenes with a total mass fraction of not more than 0.01%. In the run-out mode, data were obtained on the rotational speed and vibro-displacement of the rotor, vibration acceleration of the bearing housing. Based on the results of the experimental data processing, Stribeck curves and trajectories and amplitude–frequency characteristics of the oscillations are constructed. The results showed a decrease in friction in bearing supports when using oils with additives. At the same time, the effect on the rotor vibration level was insignificant. The best results were shown by the addition of fullerene soot.
