Influence of Surface Waviness on the Thermal Elastohydrodynamic Lubrication of an Eccentric Tappet PairSource: Journal of Tribology:;2013:;volume( 135 ):;issue: 002::page 21001DOI: 10.1115/1.4023410Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The effect of singlesided and doublesided harmonic surface waviness on the film thickness, pressure, and temperature oscillations in an elastohydrodynamically lubricated eccentrictappet pair has been investigated in relation to the eccentricity and the waviness wavelength. The results show that, during one working cycle, the waviness causes significant fluctuations of the oil film, pressure, and temperature, as well as a reduction in minimum film thickness. Smaller wavelength causes more dramatic variations in oil film. The fluctuations of the pressure, film thickness, temperature, and traction coefficient caused by doublesided waviness are nearly the same compared with the singlesided waviness, but the variations are less intense.
