ENSURING THE TECHNICAL CONDITION OF THE BEARINGS OF MARINE DIESEL ENGINES

Abstract

The purpose of the investigation was to identify the influx of antifriction coatings into the technical mill of marine diesel bearings. In the antifriction coatings, various saws were applied, a thin ball of which was applied to the surface of the bearing shells of marine diesel engines 12V32/40 MAN-Diesel&Turbo. The thickness of the epilam ball, which is adsorbed on the metal surface, was controlled by ellipsometry. It was found that the thickness of the epilamium ball on the surface of the bearing shells of marine diesel engines can reach 11.2-17.4 nm. In this case, the hour required for its adsorption does not exceed 10 minutes. It has been shown that nanoballs of epilamics, applied on a metal surface, lead to an increase in the structural characteristics of the boundary ball of the olive: thickness (from 12.3 µm to 15.2-18.3 µm), marginal cutives of moisture (from 10.2° to 15.8-17.4°). It has been experimentally confirmed that waxing the surface of bearing shells can significantly reduce their wear. For the marine diesel engine 12V32/40 MAN-Diesel&Turbo, it was experimentally established that epilamination will provide a 1.1-1.4-fold reduction in wear on the surface of the bearing shells, as well as their shorter technical production.
