COMPREHENSIVE ANALYSIS OF LOAD CAPACITY IN SPHERICAL BEARINGS CONSIDERING SURFACE ROUGHNESS AND THERMAL EFFECTS

Abstract

This study investigates the behavior of squeeze film lubrication in spherical
bearings, accounting for variations in viscosity and the influence of heat. Graphical
representations are constructed, and analytical expressions for load capacity and squeezing
time are derived and systematically analyzed. The findings illustrate that the presence of a
high viscous layer near the periphery contributes to an increase in load capacity and
squeezing time, while a low viscous layer results in a decrease in both parameters. To assess
the thermal impact on load capacity and squeezing time in spherical bearings, a parameter
denoted as "q" is introduced and scrutinized across different values.
