Abstract : The radial deflection of a thin ring due to bending by equally spaced, equal radial loads is found as a function of the angular coordinate of the ring. By expressing the angular coordinate as a function of time, the wave form of the dis placement of a point on the stationary outer ring of a rotating bearing is found. An expres sion for the RMS level of any harmonic of the vibrational velocity is found by termwise dif ferentiation of the Fourier expansion of the dis placement function. As a numerical example the RMS amplitudes are computed for an SKF 6310 single row deep groove ball bearing. (Author)
