Abstract
The paper objective is to develop new greases with increased load capacity, corrosion protection, which provide lower wear of friction units. The results of comparative laboratory tests of the physicochemical, tribo-engineering and anticorrosive properties of new Rosoil-LS-112 and Rosoil-LS-720 greases in comparison with Litol-24 grease manufactured according to GOST 21150 are presented. All tests to determine the tribo-engineering characteristics and physicochemical parameters of greases are carried out in the accredited Laboratory for Testing Technological Lubricants of Self-supporting Creative Center of Ufa Aviation Institute. As a result of the tests carried out, it is found that Rosoil-LS-112 grease surpasses Litol-24 in tribo-engineering properties determined on a four-ball friction machine. Rosoil-LS-720 grease, in relation to Litol-24 and Rosoil-LS-112 greases, has a bette protective ability in salt fog.
