Open containment frame for roller applied deep compression treatment of shaft products

1. A suspended supporting device for roller compression treatment of rotating shaft products, comprising:

a containment frame including:

a main portion;

an articulating arm including an attachment for a roller cartridge; and

a roller cartridge attached to the attachment;

a support element attached to the main portion and providing internal stabilization to the supporting device;

a mechanism providing motion to the articulating arm with respect to a part of the main portion that is opposite to the roller of the articulating arm to impart compression treatment to a shaft positioned there-between; and

an attachment mechanism for suspending the suspended supporting device above ground via attachment to an overhanging external element.

2. The suspended supporting device of claim 1 , wherein the external element comprises an overhanging crane unit having a vertical suspension element.

3. The suspended supporting device of claim 1 , wherein the support element comprises a bracket element attached to the main portion and further wherein the support element includes the attachment mechanism.

4. The suspended supporting device of claim 1 , wherein the attachment mechanism comprises an eyelet.

5. The suspended supporting device of claim 1 , wherein the main portion includes an attachment for at least one roller cartridge.

6. The suspended supporting device of claim 1 , wherein the main portion includes an attachment for at least two roller cartridges.

7. The suspended supporting device of claim 1 , wherein the attachment for a roller cartridge is configured to attach a roller cartridge in releasable fashion.

8. The suspended supporting device of claim 7 , wherein the main portion includes an attachment for at least one roller cartridge;

wherein the attachment for at least one roller cartridge of the main portion is configured to attach a roller cartridge in releasable fashion.

9. The suspended supporting device of claim 1 , wherein at least one of the main portion and the articulating arm includes rollers of varying width profiles attached to attachments for roller cartridges.

10. The suspended supporting device of claim 1 , wherein the main portion and the articulating arm are configured to permit insertion and retention of a work piece of at least 220 mm in diameter.

11. The suspended supporting device of claim 1 , wherein the mechanism providing motion to the articulating arm with respect to the main portion comprises a hydraulic cylinder.

12. The suspended supporting device of claim 1 , wherein the mechanism providing motion to the articulating arm with respect to the main portion comprises two or more hydraulic cylinders.

13. The suspended supporting device of claim 12 , wherein the two or more hydraulic cylinders comprise:

a first hydraulic cylinder positioned to move an end of the articulating arm about a pivot point with respect to the main portion; and

a second hydraulic cylinder positioned to move the main portion with respect to the support element.

14. The suspended supporting device of claim 13 , wherein the support element comprises a bracket attached to the main portion.

15. A method for roller compression treatment of rotating shaft products using a suspended supporting device, comprising:

positioning a vertically suspended containment frame about a work piece, the containment frame including: a main portion; and an articulating arm including an attachment for a roller cartridge having one or more rollers attached thereto;

imparting compression force via the one or more rollers to the work piece via a mechanism providing motion to the articulating arm with respect to the main portion to impart compression treatment to a shaft positioned between the one or more rollers and the main portion; and

rotating the work piece about a central axis;

wherein the vertically suspended containment frame does not rotate.
