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.
