- the toothing can be inside or outside the sleeve.
- the spur toothing in the workpiece is formed using the pressure rolling technology.
- the workpiece located on a molding tool is pressed using spinning rollers plastically cold formed.
- the thickness of the workpiece is reduced and the area is increased by pulling out the material, which is below the Pressure of the spinning rollers fluidizing material in a tooth structure of the mold is pressed.
- An advantage of pressure rolling it is that, due to the cold forming, the finished Workpiece has a uniform structure.
- the molding tool is surrounded by a displaceable tube, with which the contact surface of the mold for the workpiece is enlarged can be.
- the workpiece is withdrawn from the workpiece, so that a The edge of the workpiece protrudes beyond the molding tool.
- This edge can now with the help of the pressure rollers on the mold, so that a Sleeve with a radially running toothed end face is created, the toothing is inside the sleeve.
- a hollow mandrel can be attached to the toothed workpiece serves as a support for the edge to be folded. This creates a sleeve with a radial End face, the toothing on the end face outside the sleeve lies.
- the molding tool advantageously has a centering pin for the workpiece which can also serve as an anti-rotation device for the workpiece. So will ensures that the workpiece is in rotation Spinning rolling remains exactly positioned. This increases the accuracy of the Face toothing of the workpiece.
- the pressure rollers run relative to the mold during the pressure rolling process with the workpiece on it. Either the molding tool rotates about its longitudinal axis and the spinning rollers only move in a radial direction Direction is over the tooth structure of the mold or the mold stationary and the pressure rollers are both radial and circumferential over the Tooth structure moves.
- the molding tool 1 is an example of one Shown mold.
- the molding tool 1 is cylindrical and driven to rotate about its longitudinal axis 1A attached to a machine tool, not shown.
- the molding tool 1 On the end facing away from the machine tool 2, the molding tool 1 has a negative spur toothing 3 on.

- the illustrated Tooth structure 103 is only in the radial direction trained in sections.
- the axis of rotation 107A of the Press roller 107 extends at an angle ⁇ to that Rotation axis 101A of the mold 101.
- the angle ⁇ and the peripheral surfaces of the pressure roller 107 are selected that the pressure rollers 107 before the start of the forming up can be moved to the centering pin 104 and that the pressure rollers 107 exert an axial force on the Apply workpiece 106 located on the end face 102 can.
- the angle ⁇ is at least 10 °, preferably 45 °.
- the molding tool rotates during the pressure rolling operation 101 and the pressure rollers 107 about their respective axes of rotation 101A and 107A.
- the pressure rolling takes place from the inside to the outside, i.e. that the pressure rollers 107, which at Stand at the centering pin 104, be moved outwards.
- the pinch rollers 107 are not moved exactly radially outwards, but under an angle ⁇ so that the direction of advance of the spinning rollers 107 is inclined towards the end face 102.
- the pressure rollers 107 With increasing radial distance to the axis of rotation 101A of the Forming tool, the pressure rollers 107 are thus closer to the face 102 brought up. This ensures that the pressure rollers 107 the material of the workpiece 106 press completely into the tooth structure 103.
- Fig. 2 In the upper half of Fig. 2 is one Spinning roller 107 approximately in the middle of the forming process shown. In the lower half of the figure is one Press roller 107 shown in the end position. After reaching this end position are the spinning rollers of the workpiece 106 moved away so that this from the mold 101 can be removed.
