Disk pack balancing station
View Patent ↗A method of balancing a disk pack assembly is disclosed. The disk pack assembly comprises a plurality of components including a plurality of disks coupled to a hub of a spindle motor with at least one disk spacer between the disks. The method comprises the steps of rotating a first biasing arm about a pivot to apply a first biasing force to a first component of the disk pack assembly, and moving a second biasing arm linearly to apply a second biasing force to a second component of the disk pack assembly.
1. A method of balancing a disk pack assembly, the disk pack assembly comprising a plurality of components including a plurality of disks coupled to a hub of a spindle motor with at least one disk spacer between the disks, the method comprising the steps of:
(a) rotating a first biasing arm about a pivot to apply a first biasing force to a first component of the disk pack assembly; and
(b) moving a second biasing arm linearly to apply a second biasing force to a second component of the disk pack assembly.
2. The method as recited in claim 1 , wherein the first component comprises the at least one disk spacer.
3. The method as recited in claim 1 , wherein the first component comprises at least one of the disks.
4. The method as recited in claim 1 , wherein the second component comprises at least one of the disks.
5. The method as recited in claim 1 , wherein if the disk pack assembly comprises an even number of disks, the first component comprises the at least one disk spacer.
6. The method as recited in claim 1 , wherein if the disk pack assembly comprises an odd number of disks, the first component comprises at least one of the disks.
7. The method as recited in claim 4 , wherein moving the second biasing arm further comprises allowing an abutment of the second biasing arm to rotate about a pivot to apply a second biasing force to the second component.
8. The method as recited in claim 7 , wherein:
the second component comprises at least two of the disks; and
the abutment rotates about the pivot in order to equalize the second biasing force applied to the at least two disks.
