  • Vibration of a Tapered Roller Bearing Excited by

    The vibration of a TRB (tapered roller bearing) excited by a localized damage on a rotating cone (inner ring) raceway was studied using a three-dimensional, non-linear vibration model. Bearing vibration responses were analyzed in three directions. The responses exhibited multiple BPFI (ball passing frequency, inner) harmonics.
