FEATURES OF LUBRICANE LAYER CREATING IN A LOCAL CONTACT

The article presents the results of research influence rolling speed parameter during pure and 20% with slip on kinetics formation lubricant layer thickness in central contact zone. aim experimental is establishing impact operational parameters friction pairs - (a slip) dynamics process forming zone between contacting surfaces «steel ball glass disc.» Oils various purpose were used work, namely motor oils for gasoline diesel engines (М8Г2К, М10Г2К), universal oil (SAE15w40LUX) motor­gear (ЄМТ-8, ЄМТ ПРОТЕК) (I-40). increase was shifted from 0 to 1.8 m / s; at a volumetric temperature (об'ємній температурі) 20°С; stress 251.5 MPa. lubricating determined by optical interferometry. According researches concerning determination action different composition purpose, it found that period steam depends which there an zone, leading establishment appropriate lubrication modes (from boundary hydrodynamic). Decisive role kinematic viscosity lubricant, base quantitative content additives. Based data obtained conditions slip, favorable reducing initial setting maximum regime when using contained surfactants polar molecules. KEY WORDS: ELASTOHYDRODYNAMIC CHARACTERISTICS, ROLLING SPEED, CLEAN ROLLING, SUSPENSION THICKNESS OF THE LUBRICATION LAYER
