Abstract

A tolerance ring for coupling an actuator arm to a pivot bearing while maintaining mass eccentricity of the actuator arm. The tolerance ring having a substantially cylindrical base portion with a first radius about a central axis and extending a length parallel to the central axis, the cylindrical base portion has a first tab and a second tab extending along the length of the cylindrical base portion, the first tab being positioned proximate to the second tab. The tolerance ring improves mass eccentricity by radially displacing the first tab at a second radius about the axis such that a radial gap is formed between the first tab and second tab.

Description

technical field [0001] The present invention relates generally to tolerance rings for use with bearings. More specifically, the present invention relates to tolerance rings for use between cartridge bearings and actuator arms of information storage devices. Background technique [0002] A key component of any computer system is the device that stores data. A common place in a computer system to store large amounts of data is on a disk drive. The most basic components of a disk drive are the spinning disk, the actuators that move the transducers to various positions on the disk, and the circuitry that reads and writes data to and from the disk. A head gimbal assembly (HGA) including a magnetic head and a metal suspension is coupled to the actuator. The HGAs can be stacked together to form a head stack assembly (HSA), which is pushed across the disk surface by an actuator. A variety of disk drives are used today such as hard drives, zip drives, floppy drives. All drives u...
