Abstract
The main design parameter of spindle bearings is the ball advance and retardation in addition to the maximum contact pressures and the spin-to-roll ratio. This value describes the leading and trailing motion of the balls in the cage pockets in radially loaded spindle bearings. With a new measuring system, the motion of the balls can be precisely measured along the bearing circumference. At the same time, the developed test rig offers the possibility to load the bearing with dynamic forces. The results show an increase in the ball advance and retardation when dynamically load - ed with the cage and the technically relevant shaft rotational frequency compared to the static case. A load with multiples of the shaft rotational frequency does not lead to a significant increase of the ball advance and retardation.
