The dynamic model of the cylindrical roller bearing cage was established, and the influences of outer ring oil groove size, the roller chamfer size, the radial clearance and the guide clearance parameters on the dynamic characteristics of the cylindrical roller bearing cage were analyzed. The results show that unsuitable size of the oil groove of bearing outer ring can reduce the stability of the cage rotation, which leads to high slip rate and high main stress of the cage; the chamfering size of the roller has little influence on the stress condition of the cage, but reasonable chamfering radius size of the roller is beneficial to the stable operation of the bearing cage, and can reduce the slip rate of the cage; the increase of the radial clearance of the bearing can increase the slip rate and the main stress of the cage and accelerate fatigue failure of the cage; unreasonable guide clearance can greatly reduce the motion stability of the cage, too small guide clearance leads to too large friction between the cage and the guide surface, which is easy to cause wear and failure, while too large guide clearance can increase the vortex range of the mass center of the cage, and reduce the stability.
