Rib roller - end contact of tapered roller bearings

rib-rollerTheend contact is the essential partresponsible for carrying the axial loading ofroller bearings. Most of wear failures occurtaperedat thiscontact due to slip and side slip, high spin to rollingratio and insufficient area for the oil film pressureto be build-up.The present work is concerned withfrom the vibrational point of view,this contactin order tofailurerunningaxialunderloads,differentspeeds,diagonose itswhenconditions ofoperatinglubrication,and mounting fits.dealsToitsobject,achivethisstudythedynamictheoreticallyexperimentallyandwithresponse of an axialy loaded tapered roller bearing. Inthe theoretical part, a mathematical model, which is anadaptation of a similar one made for the ball bearings,was elaborated to simulate the tapered bearings. The
