    专利说明:

    The invention relates to a bearing assembly with a bearing cap and an adjacent bearing block.
    Split bearing arrangements, for example for connecting rods or crankshafts, are known from the prior art. These usually consist of a bearing block and a bearing cap, wherein between these two the bearing is designed for a shaft. To form the bearing while a snug fit the bearing cap on the bearing block is essential. This custom-fit seat should not only be maintained during operation of the storage, but this should be restored after any dismantling of the bearing cap, including the bearing cap to take back exactly the position on the bearing block, which he had before disassembly.
    In order to achieve this, the bearing block and the bearing cap are often produced in one piece and then broken apart. A popular on the market other solution for positioning the bearing cap is the centering means minor overlap of the bearing cap on the bearing cover length in conjunction with a precisely manufactured bearing lane on the bearing block. In this solution, both a well-manufactured storage lane but also a tightly tolerated bearing cover length to avoid excessive coverage required so as not to get too high stress-induced voltage when the bearing cap is stretched in the storage chair. These required bearing cover tolerances can only be achieved by means of mechanical reworking or by calibrating the bearing cap.
    The object of the present invention is to provide a split bearing assembly in which the influence of tolerances on stress induction can be reduced.
    The object of the invention is achieved in the bearing arrangement mentioned above, characterized in that the bearing block in the region of the arrangement of the bearing cap has a recess in which the bearing cap can be arranged, and that the bearing cap has vertically extending deformation elements with a longitudinal extent, said vertically extending Deformation elements have higher plastic deformability than the bearing block.
    The advantage here is that the deformation elements can be plastically deformed by the latter during the clamping of the bearing cap on the bearing block. Thus, the slight overlap of the bearing cap with respect to the position chair is no longer required, whereby the influence of the manufacturing tolerances of the bearing cap can be reduced to the voltage induction. It can thus be simplified, the production of the bearing assembly, since a machining reworking or calibrating the bearing cap no longer needs to be performed. By saving processing steps, the manufacturing cost of the bearing assembly can be reduced.
    According to one embodiment variant of the bearing arrangement, it can be provided that the deformation elements are formed by webs and / or grooves. It can thus be simplified, the assembly of the bearing assembly, as can be performed by these deformation elements of the bearing cap during the clamping easier.
    It may further be provided that the recess of the bearing block is limited to the arrangement of the bearing cap of side walls, said side walls further deformation elements having a smaller cross section than the deformation elements of the bearing cap, each viewed in the same direction. It is thus on the one hand better clamping of the bearing cap with the bearing chair reachable. On the other hand, these deformation elements may also be formed opposite the deformation elements on the bearing cap, whereby the introduction of the deformation elements on the bearing cap in the mating surface on the bearing block can be simplified, in particular the extent of material displacement can be reduced by the deformation elements on the bearing cap.
    For better insertion of the deformation elements on the bearing cap in the mating surface on the bearing block can be provided that the deformation elements of the bearing cap over the longitudinal extent are at least partially tapered or formed with a facet. In particular, it is advantageous if the initial region of the deformation elements on the bearing cap, ie the region which first comes into contact with the mating surface on the bearing block, is tapered or formed with a facet, whereby the material displacement in the mating surface on the bearing block at the beginning of the tensioning the bearing cap can be simplified with the bearing block.
    For the same reasons, provision may also be made for the deformation elements of the bearing cap to have an at least approximately triangular or trapezoidal cross-section, viewed in the direction of the longitudinal extent.
    For better absorption of transverse forces can be arranged per vertical bearing surface of the bearing cap, with which the bearing cap rests on the bearing block, at least two deformation elements.
    Preferably, the deformation elements of the bearing block are at least approximately complementary to the deformation elements of the bearing cap. It can thus be simplified the plastic deformation of the deformation elements of the bearing cap.
    An improvement in the tension of the bearing cap with the bearing block can be achieved if at least one positioning element is arranged on the horizontal plane surfaces, over which the bearing cap and the bearing block abut each other.
    For a better understanding of the invention, this will be explained in more detail with reference to the following figures.
    In each case, in a highly simplified, schematic representation:
    1 shows a cross section through a bearing assembly.
    FIG. 2 shows a side view of the bearing arrangement; FIG.
    3 shows a detail of the bearing arrangement in the region of the deformation elements in cross section;
    Fig. 4 is an oblique view of the bearing cap;
    Fig. 5 shows a detail of a bearing assembly in the region of the deformation elements in cross section.
    By way of introduction, it should be noted that in the differently described embodiments, the same parts are provided with the same reference numerals or identical component names, wherein the disclosures contained in the entire description can be mutatis mutandis to the same parts with the same reference numerals or component names. Also, the location information chosen in the description, such as top, bottom, side, etc. related to the immediately described and illustrated figure and these position information in a change in position mutatis mutandis to transfer to the new location.
    Figs. 1 to 4 show a split bearing assembly 1, as used for example in a machine housing of a reciprocating engine or a connecting rod. This bearing assembly 1 comprises a bearing block 2 and a bearing cap 3, which together form a sliding bearing 4 for example, a crankshaft. The bearing cap 3 has at its two distal end regions in each case a clamping surface 5 and the bearing block 2 at its two end regions in each case the clamping surfaces 5 opposite counter-clamping surfaces 6. For the bracing of the bearing block 2 with the bearing cap 3 in each case a through hole 7 is arranged in the distal end regions. In this hole 7 is a bolt 8 its recording. The bolt 8 engages in a thread of a blind hole in the bearing block 2, whereby the bias can be achieved. Alternatively, in the bearing block 2, the bore can be made continuously and, where appropriate, without internal thread. In this case, the bias is achieved via a corresponding, mounted below the bearing bracket 2 on the bolt 8 nut.
    The bearing block 2 has a recess 9 in which the bearing cap 3 is accommodated. Thus, the counter-clamping surface 6 of the bearing block 2 is offset relative to an outer surface 10. The recess 9 is bounded laterally by side walls 11. The lower end forms in the area of the system of the bearing cap 3, the counter-clamping surface. 6
    In the illustrated embodiment of the bearing assembly 1, the recess 9 in the axial direction (direction perpendicular to the paper plane) has a rectangular cross-section (without consideration of the recess 9 below the recess forming part of or for the sliding bearing (s) 4). However, this cross section is not restrictive. Rather, this cross section depends on the shape of the bearing cap 3 - viewed in the same direction - in the region of the recess. 9
    By matching the cross section of the recess 9 on the shape of the bearing cap 3, the latter is at least approximately, in particular, vertically extending bearing cover side walls 12 on the side walls 11 of the bearing block 2 on or at least approximately, so that a thin gap 13 between the bearing cover side walls 12 and the side walls 11 may be, as shown in Fig. 3. A gap width 14 of the gap 13 can be selected from a range of 5 pm to 1000 pm.
    As can be seen from FIG. 2, at least one deformation element 15 is arranged or formed on each of the two vertically extending bearing cover side walls 12 with which the bearing cover 3 can be positioned on or in the bearing seat 2.
    It should be noted that the two bearing cover side walls 12 need not necessarily extend vertically (although this is the preferred embodiment), but also, for example, obliquely, at an angle to
    Can extend horizontally, so that the bearing cap 3 tapers in the direction of the bearing block 2.
    In the illustrated, preferred embodiment of the bearing cap 3, two such deformation elements 15 are arranged or formed per bearing cap side wall 12. However, fewer or more than two such deformation elements 15 can also be arranged or formed, for example three, four, five, etc.
    The two deformation elements 15 per bearing cover side wall 12 are in particular spaced apart from axial end faces 16 of the bearing cap 2 and eccentrically arranged or formed at a distance from each other, as shown in FIG. 2 can be seen.
    In the preferred embodiment of the bearing cap 3, the deformation elements 15 are formed as webs projecting beyond the bearing cap side walls 12, as can be seen from FIGS. 3 and 4. However, the deformation elements 15 may also have a different shape, for example, they may be formed as grooves, which are introduced as depressions in the bearing cover side walls 12.
    It is also possible that on the or the bearing cover side walls 12 differently shaped deformation elements 15 are arranged or formed, for example, both webs and grooves.
    The deformation elements 15 may extend from the plane of the clamping surfaces 5 over an entire bearing cover sidewall height 17. But it is also possible that the deformation elements 15 extend only over a portion of this Lagerdeckelseitenwandhöhe 17, but in any case the arrangement should be such that the deformation elements 15 also extend at least over a portion of a side wall height 18 of the side walls 11 of the bearing block 2 ,
    The vertically extending deformation elements 15 have a higher plastic deformability than the bearing block 2. This can be achieved in that the deformation elements 15 are made of a softer material than the bearing block 2 and / or that the deformation elements 15 have cavities, such as pores, which are at least partially compressed during plastic deformation. In the latter case, the deformation elements 15 may in particular consist of a sintered material.
    But it is also possible that the entire bearing cap 3 is made of the material from which the deformation element 15 are made.
    In particular, the deformation elements 15 and the bearing cap 3 consist of a metallic material, for example aluminum or an aluminum alloy or a magnesium alloy. The bearing block 2 consists in particular likewise of a metal or a metal alloy, for example of cast iron.
    By clamping the bearing cap 3 with the bearing block 2 via the bolt 8, the deformation elements 15 are plastically deformed by the side walls 11 of the bearing block 2 by material displacement, whereby the positioning of the bearing cap 3 and the repositioning of the bearing cap 2 after its disassembly, for example, to the plain bearing 4 can be achieved, so that the bearing cap 3 again assumes the correct position relative to the bearing block 2 during reassembly. Due to the plastic deformability, only a small stress induction in the material of the bearing cap 3 occurs in the region of the deformation elements 15.
    The deformation elements 15 can have a constant cross-section over an entire longitudinal extension 19. However, according to a further embodiment variant of the bearing arrangement 1, it is also possible for the deformation elements 15 of the bearing block 2 to be at least partially tapered over the longitudinal extension 19, as can be seen from FIG. 4, or provided with a facet. In particular, a pointing in the direction of the clamping surface 5, lower portion 20 of the deformation elements 15 is tapered or formed with a facet, for example, formed tapered. It can thus the penetration of the deformation elements 15 in any existing
    Grooves in the side walls 11 of the bearing block 2 when clamping with the bearing cap 3 are simplified. For a better plastic deformability, the deformation elements 15 of the bearing cap 3 may also have a conically tapering course over at least a range of 20% to 100% of their longitudinal extension 19, so that they in particular from the lower end, in the assembled state of the bearing assembly 1 of the counter-clamping surface 6 of the bearing chair 2 faces, starting to be wider.
    It is also possible that the deformation elements 15 are arranged only beginning at a distance 21 to the plane of the clamping surfaces 5, as shown in FIG. 5 can be seen. It can be simplified so that the insertion of the bearing cap 3 in the recess 9 of the bearing block 2. The distance 21 may be selected from a range of 0.5 mm to 15 mm.
    For better plastic deformability and possibly for easier penetration into grooves, the side surfaces 11 of the bearing block 2, the deformation elements 15 may have an at least approximately triangular cross-section - viewed in the direction of its longitudinal extension 19 - so that they are thus formed in the manner of cutting. By at least approximately is meant that the deformation elements 15 may also be partially provided with a rounding. In particular, the tip of the triangle can be rounded, as shown in FIG. 3 can be seen. In other words, the deformation elements 15 can also have a wave-shaped cross section.
    However, other cross-sectional shapes can also be used for the deformation elements 15, for example diamond-shaped or generally polygonal cross-sections, with rounded or rounded or trapezoidal cross-sectional shapes being preferred.
    It is also possible that the deformation elements 15 a recess 22, for example, a longitudinal groove in the side wall 11 of the bearing block 2 facing region (as shown in Fig. 3 by dashed lines) and / or in at least one
    Side edge 23, whereby the plastic deformability of the deformation elements 15 can also be improved.
    Preferably, the longitudinal extension 19 of the deformation elements 15 is greater than a height 24. The height 24 is the projection of the deformation elements 15 via the bearing cover side wall 12. The height 24 of the deformation elements 15 may be selected from a range of 5 pm to 3 mm.
    According to another embodiment of the bearing assembly 1, it may be provided that - as already mentioned above - further deformation elements 15 are arranged on the bearing cover side walls 12 of the bearing cover 3 and on the side walls 11 of the bearing bracket opposite the bearing cover side walls 12. These further deformation elements 15 may be formed complementary to the deformation elements 15 of the bearing cap 3, i. with a cross-sectional shape that is inverse to that of the deformation elements 15 of the bearing cap 3. As a result, the deformation elements 15 of the bearing cap 3 can interact with the further deformation elements 15 of the bearing block 2. For example, the deformation elements 15 of the bearing cap 3 as webs and the other deformation elements 15 of the bearing block 2 may be formed as grooves, wherein the webs of the bearing cap 3 engage in the grooves of the bearing block 2. In this case, the further deformation elements 15 of the bearing block 2, in particular with respect to their cross-section smaller than the deformation elements 15 of the bearing cap 3 (viewed in the same direction), so that even in this embodiment, the deformation elements 15 of the bearing cap 3 are plastically deformed.
    It should be mentioned in this context that in Fig. 3, the aforementioned embodiment variant is shown with the further deformation elements 15 in the form of grooves. In the simplest embodiment, however, the side walls 11 are formed without any deformation elements 15, i. as a flat surface without separate depressions or elevations.
    It should also be mentioned that the deformation elements 15 of the bearing block 2, if present, cause a deformation of the deformation elements 15 of the bearing cap 3 or in general a plastic deformation of the bearing cap 3 in some regions. The (further) deformation elements 15 are themselves not plastically deformed, since the bearing block 2 - as already mentioned - at least partially consists of a material which has a lower plastic deformability than the guide element 15 of the bearing cap third
    In principle, the reverse version of this embodiment is possible, that is, for example, the grooves on the bearing cap 3 and the webs are formed on the bearing block 2, and have the corresponding size ratio of the cross-sectional geometry.
    The cross-sectional area of the further deformation elements 15 of the bearing block 2 can be smaller by a value than the cross-sectional area of the deformation elements 15 of the bearing cap 3, which is selected from a range of 10% to 40%, in particular 15% to 25%, relative to the larger one Cross-sectional area (viewed in the same direction).
    According to another embodiment of the bearing assembly 1, it is also possible that not only the deformation elements 15 on the bearing cap 3 and optionally the further deformation elements 15 are formed or arranged on the bearing block 2, but that additional positioning on the clamping surface 5 of the bearing cap 3 and / or are formed on the counter-clamping surface 6 of the bearing block 2, as is known per se. These additional positioning elements can be designed in particular according to the projections described in AT 507 265 A1. It is therefore expressly made with respect to these projections on the disclosure of AT 507 265 A1, which forms part of the present description to this extent. For example, therefore, the additional positioning elements may be formed as discrete projections or as positioning webs, etc.
    The bearing block 2 and / or the bearing cap 3 can be manufactured as sintered components from a sintered material.
    The embodiments show possible embodiments of the bearing assembly 1, wherein it should be noted at this point that also various combinations of the individual embodiments are possible with each other.
    For the sake of order, it should finally be pointed out that, for a better understanding of the construction of the bearing arrangement 1, these or their components have been shown partly unevenly and / or enlarged and / or reduced in size.
