摘要： A disk clamp for clamping a number of magnetic hard disks within a disk drive has a plurality of balance weight holes and a coined index mark for use as a reference in balancing the hard disks after assembly. The disk clamp also has a coined profile located adjacent or around the balance weight holes in order to provide uniform circumferential clamp force by the disk clamp. The disk clamp has a profile that places the inner region of the disk clamp in the plastic deformation region at a certain specified clamping force at the center of the disk clamp.

摘要： A tolerance ring for applications requiring high axial static friction has contacting portions having a novel profile. The use of multiple contacting portions having a smaller size that are wedge-shaped increases rigidity and provides a directional grip that increases axial static function. Using multiple wedge-shaped contacting portions with appropriate opposite slants provides a balanced and symmetrical grip. Using inter-level wedge-shaped contacting portions with opposite slants provides a more aggressive grip while providing a tolerance ring that is more dynamically stable and has a high resonant frequency.

摘要： 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.

摘要： A method for reducing surface particle shedding of a material, specifically a suspension mounting arm for a hard disk drive, made of an alloy such as 300 Series stainless steel, by thermally conditioning the mounting arm for a desirable time period sufficient to reduce residual stress in the mounting arm while substantially maintaining its original yield strength characteristics. To ensure fabrication free from oxidation and contamination, the contained heat source can be oxygen depleted by evacuating the interior of the container to a sub-atmospheric pressure or by filling the interior of with an inert gas such as argon or a reducing gas, such as hydrogen. After thermal exposure, the material is cooled to an ambient temperature. The resulting material exhibits adequate stiffness and yield strength for assembly and operation in a hard disk drive.

摘要： A tolerance ring configured to prevent interlocking during shipping and handling. The tolerance ring has a cylinder with a first radius about an axis of rotation and a gap in the cylinder surface having a first edge and second edge extending along the axis. The gap in the cylindrical base has a first tab on the first edge and a second tab on the second edge. The first tab is adapted for coupling to the second tab and thereby prevents the interlocking of one tolerance ring with another. The gap can be configured to be non-linear.
