LUBRICATING COMPOSITION FOR AXIAL HINGED SCREWS FOR HELICOPTERS

摘要

FIELD: production of low temperature congealing grease composition for helicopters propellers axial hinges. SUBSTANCE: high serviceability of composition is achieved due to the fact, that it has as basic foundation high viscous mineral or hydrocarbon oil, antioxidation additions forming during joint operation complexes of free stable radicals that facilitate antifretting properties, and additionally has diisooctylsebacinate. Composition is used in different heavily loaded bearing joints ( with rolling bearings), that are operated in specific conditions of swinging motion, in which contact fretting-corrosion processes are playing special role. Composition is all-seasoned and its temperature of congealing depends on basic oil choice. EFFECT: high serviceability of composition.
