Abstract
A system and method for reducing resonance in a data transfer system are herein disclosed. A data transfer system comprises a bearing and a guide member. The bearing further comprises an outer ring. The guide member is arranged relative to the bearing so as to guide the outer ring for movement relative to the guide member, and to induce an axial preload in the bearing assembly.
Claims20
A data transfer system, comprising:
- a bearing assembly comprising:
- an outer ring comprising a flat outer face;
- and
- a shaft disposed along an axis of rotation of the bearing assembly;
- a guide member arranged relative to the bearing assembly so as to:
- guide the outer ring for movement relative to the guide member;
- and
- apply a force to the outer face, the force perpendicular to the shaft and perpendicular to the guide member;
- wherein the outer ring converts a portion of the applied force to an axial force thereby axially pre-loading the bearing assembly.

An actuator system, comprising:
- a bearing comprising:
- a shaft;
- and
- an outer race that rotates about the shaft, the outer race comprising
- a flat outer surface extending from side to side of the outer race;
- and
- a guide member in contact with the outer surface;
- wherein the guide member applies a force to the outer race, the force perpendicular to the shaft and perpendicular to the guide member;
- wherein the outer race converts at least a portion of the applied force to an axial force that reduces resonance in the actuator system by axially pre-loading the bearing.
6 more elements
A tape drive, comprising:
- an actuator assembly that moves a tape head, the actuator assembly comprising:
- a bearing comprising:
- a shaft;
- and
- an outer race that rotates about the shaft, the outer race comprising a flat outer surface;
- and
- a guide member that applies a force perpendicular to the shaft, to the outer surface;
- wherein the outer race converts the applied force to an axial preload force in the bearing.
