Theoretical and Experimental Evaluation of Edge Stresses Under Severe Edge Loads

Abstract

The purpose of the paper has been to present a comparison of theoretically predicted and experimentally measured pressures between nearly cylindrical rollers. The primary theoretical and experimental tools have been described earlier, but have required some refinement to evaluate critical edge stress conditions. At misalignment levels on the order of 0.86 to 1.25 × 10⁻³ radians, edge stresses on the order of 2 GPa have been measured and predicted. These stresses are more than twice the stresses that would occur for ideal line contact.
