Definitions

  • the invention relates to a device for deep rolling of transition radii on crankshafts with at least one, in a direction reciprocally movable, linear roller element with a substantially rectilinear contact surface and a corresponding, the contact surface at a distance opposite guide surface for introducing a deep rolling force in a transition radius of a Crankshaft and a means which causes a guide and a pressing force of the rolling element.
  • the device describes two linearly substantially linear rolling elements of finite length, which penetrate with a contact surface in the transition radius of a journal of a crankshaft under a deep rolling force.
  • the crankshaft is supported by a known support member.
  • the support element consists for example of a prismatic ruler or of support rollers, which are arranged in a support roller head.
  • a force introduction area At a distance from the contact surfaces is a force introduction area.
  • the force introduction region is a flat surface on which the deep rolling force acts, which is introduced into the crankshaft in the contact surface region. About the initiation of rolling forces little is said in the known document.
  • the object of the present invention is to provide suitable means by which the introduction of the deep rolling force is made possible in the linear roller elements.
  • an agent for this purpose, which consists of a guide roller which is rotatably mounted in the housing of a deep rolling tool and, based on the guide roller, circular guide surface to which the guide surface of the rolling element hugs.
  • a guide roller of a deep rolling tool which is known per se in connection with deep rolling rollers, to transfer the deep rolling force to the linear rolling elements and to guide the rolling elements simultaneously in their working direction.
  • the guide surfaces of guide roller and rolling element are curved.
  • This curvature which relates to the cross section of both the guide roller and the rolling elements, is preferably circular arc-shaped.
  • the contact surface of the rolling element to the crankshaft has a radius of curvature which is smaller than the radius of curvature of the guide surface of the rolling element. This results in different surface pressures in the area of the guide surfaces of roller element and guide roller and in the area of contact surface and transition of the crankshaft.
  • the contact surface of the rolling element can be curved in its longitudinal extension, as already provided in EP 1 779 972 A2 (see column 13, lines 35 to 39).
  • the guide roller is mounted laterally movable in the housing in the direction of its axis of rotation. This can cause irregularities in the transition radii of a crankshaft, as they inevitably occur again and again, be compensated by moving the guide roller within the deep rolling tool. A consequence of this is that upon axial movement of the guide roller, the rolling elements pivot about a longitudinal axis which is in the direction of the longitudinal extension of the rolling elements.
  • two mutually parallel rolling elements are provided within a deep rolling tool, for each transition radius of a.
  • the two rolling elements are held by a captive on the housing of the deep rolling tool.
  • Cooperating with the captive can be provided, for example, at each of the two ends of the elongated rolling elements in each case a connecting spring.
  • FIG. 3 shows a section through the deep rolling tool along one of the lines IH-III or HMII 'of FIG. 1,
  • FIG 4 shows a section of the deep rolling tool looking in one of the directions A or B.
  • a bearing pin 2 is shown schematically in Figure 1.
  • the bearing journal 2 may be both a main bearing journal and a crank journal.
  • the respective axis of rotation of the journal 2 is indicated by the dash-dot line 3.
  • the cylindrical surface 4 of the journal 2 is bounded by transition radii 5 and 6, which are formed in the present case as recesses.
  • transition radii 5 and 6 the oil bundles 7 and 8 close, which pass into the cheeks 9 and 10 of the crankshaft 1.
  • the deep rolling tool 11 consists of the two linear roller elements 12 and 13, which are shown in Fig. 2 in cross section.
  • the two rolling elements 12 and 13 penetrate with their respective contact surfaces 14 and 15 under the action of a deep rolling force F in the transition radii 5 and 6 a.
  • the application of the deep rolling force F on the rolling elements 12 and 13 is done by a guide roller 29, which at the same time takes over the leadership of the two rolling elements 12 and 13 in its longitudinal direction, ie perpendicular to the plane of FIG.
  • the guide roller 29 as well as the rolling elements 12 and 13 are each shown in section.
  • the guide roller 29 is rotatably supported by a pin 16 and needle bearing 17 in the housing 18 of the deep rolling tool 11.
  • the deep rolling force F is applied to the two rolling elements 12 and 13 via the housing 18 and the guide roller 29.
  • the rotatably mounted in the housing 18 guide roller 29 is also movable in the axial direction 19 by a limited amount at the same time.
  • the axial mobility 19 of the guide roller 29 has the consequence that the rolling elements 12 and 13 can still pivot about one of their longitudinal axes 20 and 21 respectively.
  • This movable adjustability irregularities of the transition radii 5 and 6 can be compensated.
  • the two rolling elements 12 and 13 are each rounded off with a first rounding radius 22.
  • This rounding radius 22 is in each case opposite a rounding radius 23 of the guide surface 35, with which the two rolling elements 12 and 13 are rounded on its opposite side.
  • the second rounding radius 23 is considerably larger than the first rounding radius 22.
  • the two rolling elements 12 and 13 nestle against the guide surface 35 on the two circular guide surfaces 24 and 25 of the guide roller 29.
  • the term "circular" with respect to the guide surfaces 24 and 25 is to be understood in view of the roller-like shape of the guide roller 29.
  • the guide surfaces 24 and 25 may have a radius of curvature in their cross-section which, in addition to the circular shape, also has other possible contours, such as for example, elliptical or otherwise has.
  • a loss prevention device 26 is also on Housing 18 is provided. As can be seen in Figure 1, the captive 26 is attached to the two front ends 27 of the housing 18.
  • the possibilities of designing a captive 26 are diverse. It is important that the captive 26 secures the rolling elements 12 and 13 in a position on the housing 18 of the deep rolling tool 11, which allows the rolling elements 12 and 13 a certain rotational mobility about their longitudinal axes 20 and 21 on the one hand and prevents the rolling elements 12 and 13 at the same time, to fall out of the deep rolling tool 11 out.
  • sheets 28 are provided, for example, which are attached to the front ends 27 of the housing 18.
  • the rolling elements 12 and 13 may have different cross-sectional shapes. These different cross-sectional shapes are mentioned here only by way of example. It is therefore not intended to accommodate rolling elements 12 and 13 with different cross-sectional shapes at the same time in one and the same deep rolling machine 11. Rather, such a deep rolling device will have either two rolling elements 12 of the same first cross-sectional shape or two rolling elements 13 of deviating second cross-sectional shape. Whichever cross-sectional shape is given preference depends on the particular conditions of use of the deep rolling tool 11 and the space available.
  • two guide support rollers 30 and 31 are also provided in the housing 18 of the deep rolling tool 11.
  • the guide support rollers 30 and 31 ensure that the linear rolling elements 12, 13 each maintain their orthogonal position relative to the rotation axis 3 of the crankpin 2 and also with respect to the deep rolling tool 11, regardless of how far the projection 32 or 33 of the rolling elements 12 and 13 is dependent on the respective rotational position 34 of the crank pin 2.
