THE LUBRICANT INFLUENCE IN A TRANSLATIONAL MOBIL PAIR UPON THE VIBRATION OF AN ELASTIC KINEMATIC ELEMENT PART OF A CRANK AND CONNECTING - ROD ASSEMBLY WITH SLIDE - BAR

摘要

The paper presents the determination by experiment of the vibration of an elastic kinematic element like a component part of a crank and connecting rod assembly with slide-bar, succesively lubricated by two kinds of oil. The oils were chosen with different lubricating properties and different viscosities (one of them with much better qualities than the other). There are also evidenced the moments when the phenomenon of cavitation appears with the breaking of the lubrication film in the pair. So it is evidenced the influence of the lubricating oil on the mechanism working accuracy.
