Abstract

The details of the working units of agricultural machines are investigated, the reasons for their accelerated wear are determined. To reduce the rate of general wear, it is proposed to use working and conservation lubricants that protect metal parts from corrosion and have sufficient anti/=wear properties. The properties of used and newly developed lubricants have been studied.
The principle of selection of components for working and conservation lubricants is considered. Laboratory tests of the protective and antiwear properties of lubricants were carried out by standard methods, the mechanism of action of the additives added was established. It was found that the initial corrosion damage 1.5-2 times accelerates the rate of mechanical wear and contributes to the premature replacement of most units. To extend the service life of equipment in the region, the most acceptable is the use of working and conservation lubricants containing corrosion inhibitors and components from vegetable oil waste.

Key words: agricultural machinery, storage, corrosion, wear, lubrication, corrosion inhibitor.
