VERFAHREN ZUM VERBINDEN VON ZWEI METALLELEMENTEN |
摘要 |
A method and apparatus for coupling two metallic members such as a shaft and a disc. The method includes forming an annular groove on a joint face or outer circumference of the metallic member having greater deformation resistance of the two members, for example, forming uneven portions on the bottom of the groove by knurling or the like. Working the other metallic member, for example, the disc; having smaller deformation resistance near its joint face so that the joint face opposing that of the other causes plastic deformation. Causing a part of the disc to fluidize and flow into the groove, thereby coupling both metallic members together. |
