Definitions

  • EP-0 639 415 A2 a rotationally symmetrical body without cutting from a blank by cold forming by means of pulling or deep drawing and stretching and flow pressures.
  • a production method requires a large number of production steps which are also still too expensive.
  • this is Manufacturing process only suitable for rotationally symmetrical bodies which have at least one radially oriented web area, from which cylindrical areas can be molded without cutting.
  • the object of the invention is therefore to provide a method for producing a rotationally symmetrical body, in particular a ring gear for a planet carrier, which, based on a non-cutting deformation, eliminates the disadvantages described above and permits cost-effective production.
  • the object of the invention is achieved in that the tooth profile and / or the additional elements are incorporated into a sheet metal strip, that the sheet metal strip is cut to length before or after incorporation, that the sheet metal strip is bent into a rotationally symmetrical body and that the ends of the sheet metal strips are attached to one another become.
  • the tooth profile and / or the additional elements are advantageously produced without cutting by rolling, embossing or shaping. These are inexpensive manufacturing processes that also provide sufficient accuracy.
  • the rolling, embossing or forming tool be designed such that the tooth profile and / or the additional elements have the desired profile shape and / or position of the additional elements after the sheet metal strips have been bent.
  • the flanks must be more or less inclined when producing them as a straight sheet metal strip.
  • the ends of the metal strips can be connected to one another by welding.
  • the elements are advantageously designed as hook-shaped and / or T-shaped projections on one of the sheet metal strips and corresponding recesses on the other end (clinch connection). This results in a connection of the ends to one another, which ensures a good stable connection of the ends to one another both in the tangential direction and parallel to the central axis of the rotationally symmetrical body. Depending on the area of application of the rotationally symmetrical body, such a clinch connection is sufficient. It can also be produced cost-effectively, since it can be produced simultaneously with the stamping, forming or cutting to length of the metal strips.
  • the ends of the sheet metal strips can also be welded to one another even if a clinch connection is provided, for example in the spaces between the hook-shaped and / or T-shaped projections and the corresponding recesses ,
  • two weld seams can also be made, the one, as already described, is made in the gaps and the others at the ends of the hook and / or T-shaped projections and the respective base of the recesses.
  • the additional elements can be projections or recesses formed laterally on the sheet metal strips and aligned in the finished state of a ring gear, for example parallel to the central axis. With the aid of these projections or recesses, such a ring gear can be fixed or fastened to a further component, for example to a planet carrier.
  • FIG. 1 shows a perspective view of a finished ring gear for a planet carrier, which is produced by means of the inventive production method
  • Figure 2 is a side view of a larger sheet metal strip with incorporated tooth profile and additional elements in the cutout and
  • FIG. 3 shows a sheet metal strip in a perspective view corresponding to FIG. 2.
  • 1 denotes a ring gear on a planet carrier, which has a tooth profile 2 on its inside.
  • the tooth profile is designed as helical teeth.
  • the ring gear also has additional elements 3 on one side, which are made of projections or recesses exist. By means of these additional elements, the ring gear can be attached or fixed to another machine element, such as planet carriers and the like. This enables any torque to be transmitted.
  • the ring gear 1 according to FIG. 1 is produced from a sheet metal strip 4.
  • the sheet metal strip 4 can be in the form of an endless material in which the tooth profile 2 and the additional elements 3 are incorporated by means of rolling, stamping and / or shaping.
  • the required length of the metal strip 4 can then be cut off.
  • the ends After bending the correspondingly cut sheet metal strips into a circular shape, the ends can be welded together so that a dimensionally stable ring gear is created.

Abstract

L'invention concerne un procédé de production d'un corps à symétrie de révolution, notamment d'une roue à denture intérieure (1) d'un porte-satellites, le profil de dent (2) et/ou les éléments additionnels (3) étant produits sans enlèvement de matière. Ce procédé consiste à façonner le profil de dent (2) et/ou les éléments additionnels (3) dans une bande de tôle (4), à couper à longueur la bande de tôle (4) avant ou après le façonnage, à plier la bande de tôle (4) pour obtenir un corps à symétrie de révolution et à assembler les extrémités de la bande de tôle (4).
