Abstract

All multiple disk stacked storage and retrieval systems use coated disk and separate spacer rings in their disk stack assemblies. By combining the disk and spacer ring together, one can start to reduce the high manufacturing cost of machining and assembling the disk stack assembly while improving quality. With 50% fewer product parts, you have a 50% reduction in part-to-part interfacing and a 50% reduction in part tolerance stack up. This results in lower manufacturing costs and a higher quality assembly.

Integrated Data Disk and Spacer

      All multiple disk stacked storage and retrieval systems use
coated disk and separate spacer rings in their disk stack assemblies.
By combining the disk and spacer ring together, one can start to
reduce the high manufacturing cost of machining and assembling the
disk stack assembly while improving quality.  With 50% fewer product
parts, you have a 50% reduction in part-to-part interfacing and a 50%
reduction in part tolerance stack up.  This results in lower
manufacturing costs and a higher quality assembly.

      One method to integrate the disk and spacers is by turning.  An
alternative would be to cold form the flanges or to have three bosses
per side, using the upset method.
