抄録

The vibration of ball bearing caused by the passing balls appears in both radial and axial directions. In the first report the authors dealt with the radial vibration. The cause and the phenomena in the case of the axial vibration are complicated. In the second report the authors described the subharmonic vibration of the order 1/2 caused by the passing balls and showed that the axial motion became unstable for a certain region of the rotational speed. In this paper, firstly it is proved that the axial vibration of the order 2/2 caused by the pasing balls becomes unstable in the case where the number of balls is a few and for the ball bearing having many balls such motion does not appear. Secondly in the case where the outer race is slightly inclined toward the shaft it is proved that the axial vibration of the order 2/2 caused by the passing balls produces the motion like a forced vibration and shows the resonant phenomena.
