Abstract
Official abstract text for this publication.
A method may be used to produce a connecting element for transmitting rotational movements, wherein the connecting element has a joint outer part or flange and a connecting pin. The object of providing a method for producing a connecting element with a joint outer part or flange and a connecting pin, with which method weight-optimized connecting elements can be produced in a simple manner, is achieved in that a round-plate-like or tubular blank is deformed by flow forming or flow turning to form the connecting element.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for producing a connecting element for transmitting rotational movements for an articulated shaft, wherein the connecting element has a joint outer part or flange and a connecting pin, the method comprising deforming a round-plate-like or tubular blank by flow forming or flow turning to form the connecting element, wherein the deformation of the round-plate-like or tubular blank comprises producing a ball raceway and a cage raceway in the round-plate-like or tubular blank by flow forming or flow turning, wherein the method further comprises producing radially circumferential regions with a wall thickness that varies in a longitudinal direction in the connecting element using flow forming or flow turning, wherein the connecting pin is hollowed using flow forming or flow turning, wherein the round-plate-like or tubular blank has a first material volume and the connecting element has a second material volume, wherein the first material volume is substantially identical to the second material volume. 2. The method of claim 1 , wherein deformation of the round-plate-like or tubular blank by flow forming or flow turning is performed with alternating flow forming or flow turning tools. 3. A method for producing a connecting element for transmitting rotational movements for an articulated shaft, wherein the connecting element has a joint outer part or flange and a connecting pin, the method comprising deforming a round-plate-like or tubular blank by flow forming or flow turning to form the connecting element, wherein the deformation of the round-plate-like or tubular blank comprises producing a ball raceway and a cage raceway in the round-plate-like or tubular blank by flow forming or flow turning, wherein the method further comprises producing radially circumferential regions with a wall thickness that varies in a longitudinal direction in the connecting element using flow forming or flow turning, wherein the connecting pin is hollowed using flow forming or flow turning, wherein the flow forming or flow turning working steps are carried out in a single working station.
