Abstract
A bearing anti-creep interface having a drive shaft, a bearing race, and a hub. The drive shaft extends along a rotational axis. The bearing race has an inner surface press-fit onto the drive shaft and an axial end surface defining a bearing race interface surface. The hub has an inner surface rotationally coupled to the drive shaft and an axial end surface defining a hub interface surface. The hub interface surface is in contact with the bearing race interface surface to form an interlockingjoint. The interlocking joint is configured to transfer rotational creep force of the bearing race about the rotational axis and relative to the drive shaft into an axial pressure force applied to the hub in a direction parallel with the rotational axis.
