Antifriction Plastic Greases Based on Intermediate Products of Oil Refining and Liquid Crystalline Compounds

Abstract

The rheological and triboengineering properties are presented of hydrated calcium plastic greases based on intermediate products of oil refining (hydrofined vacuum gas oil and vacuum distillate). It is shown that application of liquid crystalline cholesterol compounds as an additional component of the dispersion medium of plastic greases permits significant reduction of the wear and losses for friction and boosts the load – bearing capacity of tribocouples.
