Abstract
The present invention provides a centering assembly for centering a plurality of disks being assembled onto a spindle hub, and further provides a spindle hub being capable of centering disks being assembled.
Claims17
A centering assembly for centering a plurality of disks being assembled onto a spindle hub, said centering assembly comprising:
- a plurality of curved leaf springs for providing means for centering the plurality of disks by contacting their inner diameters;
- and
- a curved leaf springs actuator system for operating the plurality of curved leaf springs;
- thereby the curved leaf springs actuator system controls the motion of the plurality of curved leaf springs so as to cause the plurality of curved leaf springs to contact the inner diameter of the disks, resulting in the centering of the disks being assembled on the spindle hub.
