Abstract
Official abstract text for this publication.
A device including a first axial portion, a second axial portion, and a radial portion is disclosed. A portion of the second axial portion is configured to connect to a hub. An upper surface of the second axial portion may be positioned above an upper surface of a sleeve limiter shoulder when the portion of the second axial portion is connected to the hub. The radial portion connects the first axial portion to the second axial portion. The radial portion is configured to increase stiffness by increasing surface contact between the radial portion and the sleeve limiter shoulder.
First claim
Opening claim text (preview).
What is claimed is: 1. A device comprising: a hub; a sleeve having a sleeve limiter shoulder; and a limiter structure, wherein a first portion of the limiter structure is connected to the hub, and wherein the first portion of the limiter structure is axially positioned above the sleeve limiter shoulder, and wherein a second portion of the limiter structure is axially positioned below the sleeve limiter shoulder, and wherein a third portion of the limiter structure connects the…
