Some contributions to ball bearing theory
WebDec 28, 2010 · Although the ball bearing theory may help explain the transportation, scientists and engineers are still confounded by how the mighty stones were lifted into place. One lintel that fell in 1797 had to wait almost two hundred years and the advent of the industrial revolution before a 60 ton crane (one of only two of its kind in the UK at the … WebThis paper focuses on the influence of radial internal clearance on the dynamics of a rolling-element bearing. In the beginning, the 2—Degree of Freedom (DOF) model was studied, in which the clearance was treated as a bifurcation parameter. The derived nonlinear mathematical model is based on Hertzian contact theory and takes into consideration …
