Definitions

  • the present invention relates to a composite body comprising a hub, an outer ring, and a synthetic resin material interposed between the hub and the outer ring.
  • Devices of this general type are disclosed, for example, in published German patent application no. DE 26 28 826 or in United Kingdom patent specification no. GB 243,518.
  • the composite body which is constructed as a torque-transmitting gear wheel, comprises a radially inner hub body, which is provided with external profiles and can be placed with the aid of an inner recess thereof on a shaft and an outer body, which is provided at a radial distance from the hub body, in the form of a gear rim comprising internal profiles, and an intermediate layer provided between the internal and external profiles, and an insulating layer which is intended to perform a damping function and represent an electrical insulation.
  • the inner and outer bodies are fitted on the insulating layer provided between them.
  • the outer part is likewise a gear rim comprising outwardly oriented teeth and inwardly oriented projections.
  • the inner hub body is a flange-like body with axial holes.
  • the synthetic material inserted between the two parts connects the two parts, whereby an interlocking engagement is produced by way of the holes provided in the flange of the inner part in addition to the existing adhesive force in order to transmit torque from or to the hub body.
  • the torque is likewise transmitted from or to the gear rim initially by way of the adhesive force and additionally by interlocking engagement by way of the radially inwardly oriented regions of the gear rim and the plastic regions located therebetween.
  • Teeth such as those depicted in the published German patent application, are more advantageous in this respect; however, they necessitate higher production costs, as mentioned above.
  • Another object of the invention was to provide a composite body which can be produced more economically, both in terms of the materials used and the steps required for its production.
  • a further object of the invention was to provide a composite body which is capable of transmitting high torque values.
  • the composite body which may be a gear wheel or a vibration damper or the like, may comprise:
  • the outer body or the hub body is a part made of steel, in particular a massive-formed part such as a forged steel part.
  • Such parts can be produced easily and economically.
  • the molded external and/or internal profiles do not need to be shaped by expensive machining operations.
  • An additional advantage is that the surface area is further increased due to the roughness so that an improved adhesion of the synthetic resin material, which may be a thermoplastic resin introduced, e.g., injected, between the outer body and the hub body, is achieved.
  • the surfaces of the internal and/or external profiles are treated with a cleaning process after the forming process, which cleaning process can also include at least one blasting step, e.g., sandblasting or shot blasting or the like.
  • the surface portion for producing the connection between the surfaces of the internal and/or external profiles can be increased even further by constructing at least one of the profiles in sinusoidal form or in a sinusoidal-like manner.
  • the profiles can also be constructed in such a way that they overlap each other radially.
  • One advantageous possibility for producing such a composite body is to finish-machine the outer body and to finish-machine the outer teeth, for example, by honing, grinding, scraping or the like after an optional tempering process and before the connection to the inner body, that is e.g., before the vulcanization of both parts.
  • the inner body is also finish-machined and particularly the previously tempered inner contour is precision-machined or finish-machined before the connection of the outer body and the hub body, whereby it is possible for the inner contour to be a smooth bore or to comprise teeth.
  • the composite body can be produced advantageously by finish-machining, e.g., precision-machining the inner contour of the inner part and/or the outer contour of the outer part only after the connection of the inner and outer part by the intermediate layer.
  • finish-machining e.g., precision-machining the inner contour of the inner part and/or the outer contour of the outer part only after the connection of the inner and outer part by the intermediate layer.
  • FIG. 1 is a plan view of a composite body according to the invention in the form of a gear wheel 1 ;
  • FIG. 2 is a sectional view taken along the line II--II of FIG. 1 .
  • FIG. 3 is a reduced perspective view of a composite gear wheel according to the invention.
  • the gear wheel 1 comprises a hub body 2 having an inner recess 3 and a profile 4 on its outer circumference.
  • the profile is formed of wave crests 4 a and wave troughs 4 b.
  • the outer body 5 surrounds the hub 2 spaced a radial distance from the hub body 2 .
  • This outer body is provided with a tooth profile 6 on the radial exterior thereof and with an internal profile 7 comprised of wave crests 7 a and wave troughs 7 b formed on the radial interior thereof.
  • Both profile 4 and profile 7 are shaped in a sinusoidal or sinusoidal-like manner.
  • at least one elastic sound-insulating and/or vibration-insulating intermediate layer 8 is provided, which is injected, cast-in-place or vulcanized.
  • This intermediate layer 8 can also be applied by being vulcanized, glued or the like to only one of the parts 2 , 5 , or it may be a separately produced body on or into which both the respective inner and outer parts are fitted or inserted and which is connected by being glued, fused or the like with at least one of the parts.
  • the hub part 2 and the outer part 5 are formed as forgings, and one or both the profiles 4 , 7 may have at least approximately the structure obtained during the forging process. In this case they are not machined; however, before being joined with the intermediate layer 8 or the introduction of the intermediate layer 8 between them, they may advantageously be cleaned, e.g., chemically and/or by blasting.
  • the hub body 2 Before the connection of the hub 2 and/or the outer body 5 or the insertion of the intermediate layer 8 , the hub body 2 can be finish-machined, that is to say, the optionally previously tempered round inner contour of the recess 3 is, for example, ground, hard-turned, honed or the like.
  • the inner contour can also be provided with a tooth profile 3 a, which is finish-machined after at least this tooth profile 3 a of the hub part 2 has been tempered beforehand and before assembly with the intermediate layer and/or the outer part, as described above.
  • the inner contour which is round or provided with a tooth profile, can also be untempered and machined as described above.
  • the teeth 6 of the outer part 5 can be finish-machined before the insertion or vulcanization of the intermediate layer 8 or before the application of the outer part 5 ; that is to say, before the connection of the profile 7 with the intermediate layer 8 , for example, before the gluing of the profile to the intermediate layer applied previously to the hub body 2 .
  • composite bodies constructed in this manner are particularly suitable for use in motor vehicles as torque-transmitting fixed gears or idler gears.
