Definitions

  • the present invention relates to a method for attaching connecting links of a chain by means of connecting links, which are made of a bearing steel 100Cr6. Furthermore, the invention relates to a tool for fastening connecting straps of a chain by means of connecting links, in particular for carrying out the method.
  • Chains in particular toothed chains or the like, are used primarily in vehicle construction, to z. B. as timing chains of camshafts or other components to use.
  • the chains usually have connecting straps, which are connected to one another in an articulated manner via connecting links or connecting pins.
  • the links are provided in recesses of the link plates, with the ends of the links being caulked or riveted to secure them to the link plates.
  • the connecting links made of steel such as. B 39CrNoVI 3-9.
  • This material is particularly expensive. Therefore, it is also known to use a bearing steel 100Cr6 for the links.
  • this material has the disadvantage that a link made therefrom can not be riveted or fastened readily to the connecting straps, since the rolling bearing steel can easily break because of its high brittleness. Therefore, with a chain made of this material, it is only possible to fasten the connecting links to the connecting straps by means of friction welding or other complicated fastening methods. However, this is also costly and expensive due to the high heat input.
  • the present invention seeks to propose a method and a tool for attaching connecting straps of a chain by means of connecting links with which a particularly inexpensive chain can be produced.
  • This object is achieved procedurally by a method for attaching connecting straps of a chain by means of connecting links, which are made of a bearing steel 10006, wherein the connecting member is at least partially heated and subjected to a predetermined deformation force.
  • a link made of the inexpensive bearing steel 100Cr6 can be fastened to the respective connecting straps without complicated attachment methods. Since the links not made of the bearing steel 10006 are about 2.5 times as expensive as the links made of the bearing steel 100Cr6, a particularly inexpensive chain can be manufactured by the method of the present invention.
  • the chain comprises about 122 bolts, so that a considerable savings potential can be realized thereby.
  • connecting members made of the bearing steel 100Cr6 standard components so that there is the further advantage that no additional measures in the production of different chains are required because a risk of mixing the standard components in the production is not given.
  • each end face is acted upon by a rotating tool with a predetermined contact force at a trained as a chain pin connecting member.
  • a rotating tool with a predetermined contact force at a trained as a chain pin connecting member.
  • a possible embodiment in this embodiment may provide that a carbide pin or the like is used as a tool.
  • a carbide pin or the like is used as a tool.
  • the tool on the one hand has sufficient strength and on the other hand a corresponding coefficient of friction, so as to generate in addition to the application of the deformation force and sufficient frictional heat to the part to be fastened.
  • the object underlying the present invention is also achieved by a tool for fastening connecting straps of a chain by means of connecting links, in particular for carrying out the proposed method.
  • the tool according to the invention has a rotatable hard metal pin which can be pressed with a predetermined contact force against the connecting member to be fastened.
  • the tool according to the invention can preferably be used for carrying out the above-described method for fastening connecting straps of the chain by means of the connecting links formed as chain pins. Other uses are also conceivable.
  • the hard metal pin may have a tip or the like, with which an end face of a link formed as a link pin is deformable.
  • the hard metal pin may have a diameter of about 5 mm, wherein the hard metal pin tapers, so that the tip facing the chain pin has an end diameter of about 0.5 mm.
  • Other dimensions are possible, but the dimensions mentioned have proven to be particularly suitable, in particular for chain pins, which also have a diameter of about 5 mm.
  • the tip of the tool can then be applied with a predetermined contact pressure for generating the required deformation force and corresponding rotation on the end surface of the chain pin to realize the caulking or riveting of the chain pin at least in sections.
  • the tool has a drive device or the like, with which the hard metal pin in - A -
  • Rotation can be offset.
  • the drive device may preferably cause a speed of about 3000 to 4000 revolutions per minute of the hard metal pin. There are also other speeds adjustable.
  • Figure 1 is a schematic view of a tool according to the invention in attaching a link to a chain not shown.
  • Fig. 2 is a schematic plan view of the fastened link
  • Fig. 3 is a schematic three-dimensional view of a connecting plate with fasteners attached thereto.
  • FIG. 1 shows a possible embodiment of a tool for fastening a connecting link to a connecting link of a chain.
  • the tool according to the invention can preferably be used for carrying out the method likewise proposed according to the invention for fastening connecting straps of a chain by means of connecting links.
  • the chain comprises connecting straps 5, which are connected via connecting members, such. B. chain pin 2, are hinged together.
  • the chain pins 2 are preferably made of cost-effective bearing steel 100Cr6.
  • the tool comprises in the illustrated embodiment a hard metal pin 1 having a diameter of about 5 mm.
  • the sprocket 2 facing the tip 3 has a final diameter D of about 0.5 mm.
  • the hard metal pin 1 can be rotated by a drive device not shown in rotation.
  • the rotational speed is approximately between 3000 to 4000 revolutions per minute, wherein the rotation of the hard metal pin 1 is indicated by an arrow in Fig. 1.
  • the hard metal pin 1 can be moved in the axial direction relative to the chain pin 2. This too is indicated in Fig.1 by an arrow. As a result, the hard metal pin 1 can be moved both translationally and rotationally. Due to the translatory movement, a predetermined pressing force of the hard metal pin 1 can be applied to the end face 4 of the chain pin 2, which causes a corresponding deformation force on the respective end face 4 of the chain pin 2. In addition, frictional heat is caused on the end face 4 of the chain pin 2 due to the rotation of the hard metal pin 1, so that a heat input into the respective end face 4 of the chain pin 2 takes place. In this way, the chain pin 2 can be deformed by contact force and the heat input at least in sections, to be attached to the connecting plate 5.
  • the deformation of the chain pin 2 can be seen in particular from FIG. In this embodiment, the chain pin 2 is deformed at two opposite portions 6, 7 of the edge portion of the end surface 4.
  • a connecting plate 5 is shown with two attached chain pins 2 as an example.
  • the chain pins 2, 2 'fastened by the method according to the invention and with the tool according to the invention form a particularly cost-effective chain with the associated connecting straps 5 without the risk of components being destroyed during fastening.

Abstract

L'objectif de l'invention est de créer un procédé pour fixer des mailles de liaison (5) d'une chaîne au moyen d'organes de liaison (2) qui sont fabriqués en acier de roulement 100Cr6. À cet effet, l'organe de liaison (2) est chauffé au moins par sections et sollicité par une force de déformation prédéterminée. En outre, l'invention a pour but de créer un outil (1) pour fixer les mailles de liaison d'une chaîne au moyen d'organes de liaison, en particulier pour mettre en œuvre le procédé. À cet effet, l'outil est conçu comme une pointe rotative en métal dur (3) pouvant être pressée avec une force d'application prédéfinie contre l'organe de liaison à fixer.
