  • the rollers have the shape of the later desired toothing or a shape which produces a later desired toothing.
  • an endless strip of toothing is generated, which is limited only by the length of the sheet metal blank. If additional holes or recesses in the toothing, for example for oil supply to the coupling, or even notches, special lugs, bulges, etc. are required for fastening purposes or the like, this is also possible in a simple technical manner by a corresponding shape of the rolls of the method according to the invention , Also, in the endless strip after or before the introduction of the toothing with conventional punching machines easily such holes, etc. are punched or introduced.
  • the produced endless toothing strip is cut after the introduction of the toothing in the required length and rolled up in the bending device to form a drum.
  • the ends of the strip can also be provided with a profile which simplifies the connection of the ends.
  • the toothed strip is brought to the first drive roller, which is provided with a toothed profile complementary to the toothing of the toothed strip, inclined in a horizontal orientation or to the horizontal, which is pressed against the forming roller.
  • the form roller which is also provided with a complementary tooth profile, but is resistant to deformation, rotates in the opposite direction to the first drive roller, so that the threading of the toothed strip between the first drive roller and the form roller is possible.
  • the first driving roller By pressing the first driving roller against the forming roller, the first driving roller deforms elastically in a region adjacent to the forming roller.
  • the tooth strip located between the forming roller and the first driving roller is thereby drawn around the forming roller and approximately adapts to the radius of this forming roller.
  • the tooth strip is further pulled around the forming roller and captured by the second drive roller.
  • the second drive roller continues the bending process, whereby the radius of the toothed strip continues to approach the radius of the forming roller.
  • the second drive roller is delivered in the direction of the forming roller and pressed and so bent around the toothed strip around the forming roller.
  • the second drive roller may have its own drive for this purpose.
  • the second drive roller may also be driven at a slightly higher mantle speed than the first drive roller to bend the plate as tightly as possible in the area between the first and the second drive roller around the forming roller.
  • the toothed strip is shaped into a drum shape and in this case it is placed on the forming roller, from which it can be pulled off after the end of the bending process.
  • the butt ends are joined together as required by suitable bonding methods such as laser welding, spot welding, caulking correspondingly shaped ends, or other suitable bonding methods.
  • suitable bonding methods such as laser welding, spot welding, caulking correspondingly shaped ends, or other suitable bonding methods.
  • This then creates the required toothed drum, which is attached depending on the application, for example, either on a metal plate, creating a complete pot, or, as in couplings according to the US 7,121,392 , is connected directly to the coupling housing.
  • Fig. 1 is schematically simplified a dual clutch 1 of a dual clutch transmission shown in Fig. 1 to simplify the description is not shown.
