Definitions

  • the invention relates to a method for the non-cutting production of a hub of a gear part comprising the hub from a sheet metal plate.
  • Gear parts designed as sprockets or as pulleys, in particular poly-V pulleys, are widely used in motor vehicle construction and are today often produced from a round blank by pressing processes.
  • the formation of the teeth and / or the grooves is also possible in the spinning process, while the installation of the required hub is difficult.
  • the actual hub in the area of the axis of rotation is a sleeve-shaped part of the rotating disk, which establishes the connection to the shaft, axis or a pin pushed through.
  • the manufacture of the hub of a gear part takes place in the prior art in that a prefabricated cylindrical sleeve part is connected to the gear part, usually four methods being used as the connection, namely once soldering the two components, welding the two components, the connection of the two components by friction welding and finally it is possible to manufacture the gear part by a forging process.
  • the first three methods mentioned have the disadvantage that the absolutely necessary heat treatment adversely affects the actual gear part, whereby - if welding takes place - a subsequent machining of the weld seam is necessary.
  • the cost of manufacturing the hub as a turned part is relatively high.
  • outer plate carriers As a sheet metal part, these outer plate carriers being manufactured in two press passes. A total of 27 processing stages are required to produce such an outer disk carrier. They include 10 pulling, 7 calibration, 2 ironing and pulling operations, 7 cutting operations and 1 upsetting operation. The structure is torn apart by the drawing work, i. H. the material structure is tired. In addition, drawing operations are usually associated with inaccuracies that can have a negative impact on a transmission part.
  • the object of the invention is to simplify the generic method and to carry it out in one operation, without the material structure of the transmission part being adversely affected.
  • the hub of the gear part is produced in one operation, but it is also possible that the wall thickness of the hub is greater or greater than the wall thickness of the sheet metal plate of the gear part, so that here the required strength for transmitting the torque is achieved.
  • the hub is molded onto the intermediate pulley product in one setting on a spinning machine.
  • the method there is the possibility of producing intermediate pulley products for all known manufacturing methods of pulley systems, since the thicknesses in the contour area and in the profile area of the intermediate pulley products are determined by the applied pressing method.
  • a hood 2 is shown, which is fixed to a tool 3 of a main spindle 4 by a chuck 15 belonging to the tool 3.
  • the tool 3 has a center in the axial direction projecting tool pin 5, which rests on the inside of the clamped hood 2 or comes to rest, with a front 8 resting on the outside of the hood 2.
  • FIG. 1 double arrow F 1 illustrates the direction of movement of the main spindle 4 and 8 Vorsetzer laying down the hood 2.
  • Fig. 2 shows that the attack of spinning rollers 9 and 10, the hood 2 is deformed in the direction of the cylindrical tool pin 5, with the use of a form roller 11 shown in Fig. 3, the deformation is continued until the hood has wrapped around the tool pin 5.
  • the hood 2 has partially applied as a round 6 to the top of the tool 3, while the remaining part of the hood 2 has waved around the tool pin 5 according to FIG. 3.
  • this undulating region around the tool pin 5 is pressed together by thickening rollers 12 and 14, the part of the hood 2 then serving as a hub is cylindrical, the wall thickness of this cylindrical projection 7 being greater than the wall thickness of the round blank.
  • the direction of advance of the thickening rollers 12 and 14 is illustrated by the arrows F 2 in FIG. 4.
  • the proposal according to the invention creates an inexpensive manufacturing process for gear parts equipped with a hub, with no structural changes within the gear part being caused during its manufacture, while at the same time giving the possibility of designing the wall thickness of the hub as desired.
  • the cylindrical projection 7 it is now necessary to open the cylindrical projection 7 so that it can receive a shaft or a pin.
  • the opening of the cylindrical projection 7 can either be done by cutting off the bead of the cylindrical projection 7 shown in FIG. 4, but it is also possible to open the end wall of the cylindrical projection 7 through holes or the like, so that then the final hub has the bead that adds strength.
  • the flanges 16 and 17 can then be machined for the design of the gear part.
  • 21 denotes a sheet metal plate which is connected to a main spindle 22 arranged tool is arranged in that in the illustrated embodiment, the tool 23 carries a tool pin 24 onto which the sheet metal plate 21 can be placed by means of a hole provided centrally in the sheet metal plate. 25 with a push-button is designated, which is movable back and forth and comes into contact with the tool pin 24 in its working position.
  • the presetter 25 has in the area of the sheet metal plate 21 an outer diameter that is larger than the outer diameter of the tool pin 24, so that thereby a stop designated in the drawing with 34 is created, to which the inner part of the sheet metal plate deforms Can create sheet metal.
  • a chuck cooperating with the tool 23 is designated, which, after a pressure roller 26 has bent the outer edge area of the sheet metal plate, defines this edge area of the sheet metal plate 21, so that migration of the sheet metal plate is prevented.
  • the pressure roller 21 can be moved towards the tool pin 24 in the direction of the arrow shown in FIG. 6 and, as this is particularly clearly shown in FIG. 7, reduces the mean wall thickness of the sheet metal plate 21, the material pressed by the pressure roller 26 in the space that exists around the tool pin 24 and - as FIG. 8 clearly shows - bears against the stop 34, so that a cylindrical projection 28 is thereby created, which in the pulley intermediate product forms the actual hub 27 according to FIG. 9 forms.
  • the edge area of the sheet metal plate 21 defined by the chuck 29 is thicker than the central edge area of the sheet metal plate 21 and that the cylindrical projection 28 again has a substantially greater material thickness than the middle edge area of the sheet metal plate 21.
  • this wall thickness of the cylindrical projection 28 can be determined.
  • the trailing roller 35 shown in FIGS. 7 and 8 prevents the material of the sheet metal plate 21 from bending up during the pressing process.
