Abstract
A joint assembly is provide between a machine element gear and a shaft or between two shafts. The joint is brought about by forming a predetermined configured surface on the exterior of the machine element and forming a similar configuration of the same general dimensions on a raised surface on the shaft. The shaft is initially inserted into the machine element in a light force fit so that the similar predetermined configurations on the machine element and the raised surface of the shaft are in alignment. A metal cylindrical torque ring is positioned over and surrounding the two mating and abutting predetermined surfaces. By the process of magneforming, the cylindrical torque ring is deformed inwardly to be tightly pressed against the predetermined surfaces, thereby spanning the exterior of those surfaces and providing a tight joint between the machine element and the shaft. The machine element may be a variety of elements, including, but not limited to, a gear, a sprocket, a cam or a pulley or may even be the joining of two shafts.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
