Definitions

  • the invention relates to an arrangement of a bolt in a bore according to the preamble of claim 1 and a method for positioning and securing the bolt according to the preamble of claim 8.
  • the bolt has on its end face at least one recess, preferably a groove.
  • the groove extends in the direction of a diameter through the center of the end face, ie diametrically.
  • the material of the disc, ie the bore edge is pressed by caulking, so that a positive connection between the pin and disc, ie an anti-rotation results.
  • the groove according to the invention also makes it possible, with the help of a suitable tool to bring the bolt before caulking by turning in a desired angular position - this is possible even at very small diameters.
  • the bolt can thus be twisted like a bolt with a slotted head by means of a screwdriver.
  • the frontal groove according to the invention thus fulfills two functions, namely, on the one hand, the possibility of positioning and, on the other hand, the possibility of preventing rotation due to sticking.
  • a diametrically arranged groove and two, z. B. arranged at right angles or more, z. B. star-shaped grooves may be provided.
  • Possible and within the scope of the invention would also be such recesses or shapes on the face of the bolt, which on the one hand enable the engagement of a tool for turning and on the other hand, the impressing of material of the adjacent edge of the hole in Verstemmen.
  • the invention is particularly advantageous in Planetenradbolzen with oil holes in the form of longitudinal and transverse bores, since they must be aligned before their fixation in their angular position relative to the planet carrier or its guide discs.
  • An advantage of caulking is that the relatively soft material of the planet carrier or the guide plate is displaced in the frontal groove of the planetary pin. The relatively hard material of the planetary bolt is not caulked. The bolt can thus be through hardened.
  • the object of the invention is also achieved by a method having the features of claim 8, wherein a bolt aligned with the end face groove after insertion into the bore or a planet carrier in the holes and is then fixed by caulking, which by axially advancing a Stamp is done.
  • the caulking requires less effort because of the relatively soft material; this results in lower deformation forces, which affect to a lesser extent on an inclination or entanglement of the planet pin axes. By caulking no burrs, which must be subsequently eliminated.
  • Fig. 2c is a plan view, d. H. the front of the bolt.
  • Fig. 1 shows a partially illustrated Planetenradbolzen 1, which is arranged in a bore 2 of a likewise only partially shown guide plate 3 of a planet carrier, not shown.
  • the Planetenradbolzen 1 has a longitudinal axis 1a and an end face 1b, which terminates approximately flush with the outer surface 3a of the guide disc 3 before the final assembly.
  • longitudinal bore 4 and a transverse bore 5 are arranged for the supply of oil from bearing points of the planetary gears, not shown.
  • a groove 6 extending transversely to the longitudinal axis 1 a is worked in, which penetrates the longitudinal bore 4.
  • the arrangement shown in the drawing to the left of the longitudinal axis 1a shows the Planetenradbolzen 1 in its initial position
  • the arrangement shown in the drawing right of the longitudinal axis 1a shows the Planetenradbolzen 1 after caulking by means of a stamping 7 formed as a caulking.
  • the punch 7 has an approximately frustoconical end face 7a and is delivered in the direction of the longitudinal axis 1a, ie it presses on the one hand on a bore 2 surrounding edge region 3b of the guide disc 3 and on the other hand on the end face 1b, which by the advancing movement of the punch 7, 7a is reset.
  • the material of the guide disk 3 is displaced out of the edge region 3b into the end groove 6 - as shown in the drawing.
  • the bolt 1 can be adjusted by rotation about the longitudinal axis 1a by means of a tool, not shown, which engages in the longitudinal groove 6 from the front side, that is brought into a desired angular position. Thereafter, the caulking described above.
  • FIG. 2a, 2b and 2c show the Planetenradbolzen 1 of FIG. 1 as a single part, but only partially as a longitudinal section (Fig. 2a), as a view (Fig. 2b) and as a plan view (Fig. 2c).
  • Fig. 2a shows the profile of the longitudinal groove 6, which is approximately U-shaped.
  • Fig. 2c shows the diametrical arrangement of the end groove 6, d. H. it runs in the direction of a diameter and is thus penetrated by the longitudinal bore 4.
  • Fig. 2b and Fig. 2c show a chamfer 8 on the front side of the planetary gear 1, whereby the assembly is facilitated.
  • the invention is not limited to planetary gear bolt on the embodiment shown above, but also deviations or other embodiments are conceivable, which fulfill the functions of the invention, on the one hand in an adjustability of the bolt and on the other hand in the subsequent rotation. It is of particular importance that the material of the disc or the bore edge caulked, that is plastically deformed and not that material of the Planetenradbolzens, as is the case in the prior art.
  • the material of the disc is usually softer in such arrangements, while the bolt, in particular a Planetenradbolzen, generally has a harder material or is hardened after manufacture.
  • alternative recesses or shapes on the circumference or the end face of the bolt are conceivable, in which the material of the bore edge can flow from outside to inside during caulking.
