Abstract
A method of producing a drive shaft with drive elements on a cylindrical basic part includes forming a desired contour for a drive element on pairs of discs, forming holes in the discs of each pair having axes being inclined relative to the surfaces of the discs and having inclinations being opposite to and mirror images of each other, pushing the discs onto a cylindrical basic part with the disc of each pair being congruent to each other, and pressing the discs of each pair together until they are substantially perpendicular to the longitudinal axis of the basic part.

Method of producing a drive shaft with drive elements on a cylindrical basic part, which comprises forming peripheral driving surfaces for a drive element on pairs of discs, forming circular holes in the discs of each pair of substantially the same diameter as the cylindrical basic part and having axes being inclined relative to the surfaces of the discs and having inclinations being opposite to and mirror images of each other, pushing the discs onto a cylindrical basic part with the discs of each pair being congruent to each other with the holes in the discs concentric with the outer surface of the cylindrical part and having the inclinations opposite to and mirror images of each other, and pressing the discs of each pair together until they are substantially perpendicular to the longitudinal axis of the basic part and dig into the outer surface thereof.
Method of producing a drive shaft with drive elements on a cylindrical basic part, which comprises forming a pair of discs, forming circular holes in the discs of the pair of substantially the same diameter as the cylindrical basic part and having axes being inclined relative to the surfaces of the discs and having inclinations being opposite to and mirror images of each other, loosely pushing at least one other part having a peripheral driving surface over a cylindrical basic part, pushing the discs onto the cylindrical basic part enclosing the other part with the discs of the pair being congruent to each other with the holes in the discs concentric with the outer surface of the cylindrical part and having the inclinations opposite to and mirror images of each other, and pressing the discs of the pair toward each other until they are substantially perpendicular to the longitudinal axis of the basic part and dig into the outer surface thereof.
