Definitions

  • the invention relates to a deep rolling head of a deep rolling machine for deep rolling of radii or punctures on the journal of crankshafts by means of deep rolling rollers which are held on the deep rolling head in the circumferential direction on both sides of the contact point with the journal of roller cages and guided freely rotatable therein, the roller cages on Rolling roller head are held by roller holders.
  • a deep rolling roller head of this type is known, for example WO 0224407 (&, EP 1 318 889 A1 ) which forms the basis for the preamble of the independent claim.
  • the well-known deep rolling head has fixed rollers, which are held in the circumferential direction of a crankshaft to be machined on both sides of the contact point with the journal of roller cages and guided freely rotatable therein.
  • the roller cages are held even on the deep rolling head of L-shaped holders.
  • the L-shaped holders are adjustable.
  • the known roller cages are made of plastic.
  • roller cages are for example off DE 200 23 033 U1 known. These are so-called double roller cages, that is, when the contact surface between the deep rolling rollers and the deep rolling roller cage is worn, the roller cage in the deep rolling roller head is reversed and a similarly configured contact surface at the lower end of the roller cage takes over the support and leadership of the deep rolling to this guide surface is worn.
  • the roller cages have the task to keep the fixed rollers on the deep rolling head.
  • the rear roller cage which is that roller cage, which faces the rotation of the crankshaft, Apply the forming force for the deep rolling in the circumferential direction and the frictional force between the deep rolling roller and the guide roller for the deep rolling roller in the deep rolling head. This frictional force is about 10 percent of the pressing force of the deep rolling roller head under the deep rolling force.
  • the rear, driving roller cage wears due to the friction of the deep rolling roller.
  • the contact surface between the roller cage and the deep-rolling roller gradually takes on the shape of the deep-rolling roller itself.
  • the deep rolling roller can even jam in the roller cage, but in any case the required angular mobility of the deep rolling roller is restricted and the load on the deep rolling roller increases if the changing geometric conditions of the crankshaft require an angular adjustment of the deep rolling roller.
  • the driving rear roller cage is replaced by a cage roller and provided for holding the fixed roller on the deep rolling head a holding device.
  • the cage roller is designed as a rolling bearing.
  • rolling bearings are inexpensive, since they are manufactured in mass production. They have hardened outer bearing surfaces and offer the deep-rolling roller applied thereto a low-wear contact surface. Mass-produced rolling bearings are also available with permanent lubrication and shields, which make the bearings insensitive to contamination. Overall, this results in a reduction of friction, an increase in life and the elimination of settings on the deep rolling head.
  • the cage roller should preferably be cylindrical.
  • a concave shape of the cage roller is also conceivable in order to obtain more favorable contact conditions with the deep rolling roller.
  • there should be a limited axial displaceability of the cage roller so that it can adjust to the changing geometric conditions of the journal during the deep rolling process.
  • a deep rolling roller head 1 contains a guide roller 2 which is rotatably mounted in its housing (not shown). On the guide roller 2 the deep rolling roller 3 is supported, which is provided with a radius or recess 4 (FIG. Fig. 4a ) on the journal 5 of a crankshaft (not shown) festzuwalzen.
  • a cage roller 9 is provided instead of the rear driving roller cage.
  • the cage roller 9 is rotatably mounted in a roller holder 10, wherein the axes of rotation 11 and 12 of the deep rolling roller 3 and the cage roller 9 occupy approximately the same spatial position.
  • the cage roller 9 is still movable by a small amount in the axial direction (13). While the cage roller 9 is fixed in the roller holder 10 by means of a bolt (not shown), a holding plate 14 of the deep rolling roller 3 provides the necessary protection against falling out of the deep rolling roller head. 1
  • FIG. 3 shows the roll holder 10 in different views. Of which represents the Fig. 3a a side view and the Fig. 3b a longitudinal section through the roller holder 10.
  • Die Fig. 3d shows the roll holder 10 from below and the Fig. 3e from above.
  • the Fig. 3c shows a front view of the roller holder 10 from the direction A.
  • To attach the roller holder 10 on the deep rolling head 1 is a graded Long hole 15 provided.
  • Two cage rollers 9 can be arranged in the two inclined recesses 16 and 17, wherein the center axes 18 and 19 have approximately the same inclination as the axis of rotation 11 of the deep rolling 3.
  • a bore 20 is finally used to attach the retaining plate 14 on the roll holder 10.
  • the guide roller 2 moves with its peripheral flange 22nd
  • the Fig. 4a shows a front view of the cage rollers 9 along the line II-II of Fig. 1 ,
  • the Fig. 4b arises when you make a cut through the center axis 19 and folds this section in the direction bb.
  • the cage roller 9 has a cylindrical shape and is rotatably mounted in its center 24 on a cylindrical bolt (not shown) in the roll holder 10.
  • the cage roller 9 is formed by a mass-produced axial roller bearing.
  • the cage roller 9 may also have deviating, along the center axis 18 and 19 concave recessed peripheral shapes.
  • the deep rolling roller 3 is supported on the cage roller 9.
