Abstract
Official abstract text for this publication.
A device and methods are provided for deep rolling. In one embodiment, a deep rolling tool includes a fork having a base section and a plurality of fork arms, wherein each fork arm extends outwardly from the base section and wherein the fork arms are separated from one another to form an opening. The deep rolling tool may also include a plurality of rolling elements configured to apply a compressive stress to articles received by the deep rolling tool, wherein each rolling element is mounted at the distal end of a fork arm, and wherein each rolling element includes a cantilever shaft retained by a fork arm and a crowned roller.
First claim
Opening claim text (preview).
What is claimed is: 1. A deep rolling tool, comprising: a fork having a base section; a first fork arm extending outwardly from the base section; a second fork arm extending outwardly from the base section, the first fork arm and the second fork arm each having a distal end with respect to the base section; an opening extending from the distal end of the first fork arm and the distal end of the second fork arm to the base, the opening being located between the first fork arm and the second fork arm; and a first rolling element rotatably mounted to the distal end of the first fork arm via a first cantilever shaft that is angularly offset with respect to an axis of the distal end of the first fork arm, wherein the axis of the distal end of the first fork arm is parallel to the opening; a second rolling element rotatably mounted to the distal end of the second arm via a second cantilever shaft that is angularly offset with respect to an axis of the distal end of the second fork arm, wherein the axis of the distal end of the second fork arm is parallel to the opening; and wherein the first rolling element and the second rolling element apply a compressive stress to an article when it is located in the opening. 2. The deep rolling tool of claim 1 , wherein the fork is a flexible fork tool configured to provide a compressive force based upon a flexural stiffness of the first fork arm and a flexural stiffness of the second fork arm.
