Method for improving running performance of rolling bearing

The invention discloses a method for improving running performance of a rolling bearing. The method comprises the following steps of: (1) primarily selecting basic parameters of the rolling bearing: determining the number of rolling bodies and the ripple number of a roller way; and (2) analyzing integral stress and integral vibration effect of the rolling bearing, and then selecting the bearing according to the specific requirement of an application situation: defining a phase tuning factor ko = mod (loNw/Nr), wherein in the formula, ko is the phase tuning factor, lo is harmonic order number of excitation frequency, Nr is the number of the rolling bodies, and Nw is the ripple number of the roller way. When the ripple number of the roller way is relatively prime with the number of the rolling bodies, if the phase tuning factor ko is equal to 2, 3, 4...Nr-2, the system is in a stress balance state; and when the maximum common factor of the ripple number of the roller way and the number of the rolling bodies is
