Abstract
An experimental, investigation was conducted to examine the factional healing in a viscous lubricant film and also to investigate lubricant film thickness measurement. A hydrodynamic contact was achieved by loading a shoe against a rotating, lubricated disk. Shoe and disk temperatures were measured as functions of rotation speed and interface pressure. Film thicknesses were determined by a direct capacitance technique. The study revealed shoe temperatures in the range of 306–334°K and film thicknesses of 1.39–2.14 × 10−2 mm for sliding velocities of 3.28–14.05 m·s−1 and interface pressures 2.68–4.64 × 105 Pa. The trend of film, thickness is seen to be consistent with existing slider bearing theory. A relationship of T ∼U0.425 emerges as the dependence of shoe temperature on sliding velocity.
