    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. But there are also systems known to work with positioning on the abutting horizontal flat surfaces of the bearing block and the bearing cap, wherein press the positioning during the first assembly of the bearing cap on the bearing block in the respective counter surface and thus fix the position of the bearing cap.
    For example, EP 1 075 605 B1 discloses a split bearing arrangement in a housing, comprising a bearing block and a bearing cover made of different hard materials, wherein the bearing cover, which is clamped against the bearing block and formed of a ferrous material, has sharp-edged projections projecting above its clamping surface. which can be pressed in an initial assembly of the bearing cap with force in the counter-clamping surface of the bearing block formed of a light metal and further wherein grooves are provided in the clamping surface of the bearing cap. The projections are formed cutting or pyramid profile. The grooves serve to receive the displaced during pressing in of the projections in the bearing block material of the bearing block.
    Another bearing arrangement with such depressible projections is known from AT 507 265 A1.
    The object of the present invention is to provide a split bearing assembly in which the bearing cap can be easily positioned on the bearing block.
    The object of the invention in the bearing assembly mentioned above is achieved 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 positioning, with which the bearing cap positionable on the bearing block is.
    The advantage here is that a backup against slipping and positioning of the bearing cap takes place in a plane different from the clamping plane between the bearing block and the bearing cap. It can be better absorbed so occurring in the axial direction forces. In addition, the bearing cover undergoes better support by the arrangement in a recess of the bearing block.
    According to one embodiment variant of the bearing arrangement, it can be provided that the positioning elements are formed by positioning grooves and / or positioning webs. It can thus be simplified, the assembly of the bearing assembly, as can be performed by these positioning of the bearing cap during the clamping.
    It may further be provided that further positioning elements are arranged on the side walls of the bearing block delimiting the recess. It is thus on the one hand, a better clamping of the bearing cap with the bearing block he reichbar. On the other hand, these positioning elements could also be formed opposite the positioning nierelementen on the bearing cap, whereby the introduction of positioning on the bearing cap can be simplified in the mating surface on the bearing block, in particular the extent of material displacement can be reduced by the positioning of the bearing cap.
    For better insertion of the positioning on the bearing cap in the mating surface on the bearing block can be provided that the positioning of the bearing cap have a longitudinal extent and over the longitudinal extent are at least partially tapered. In particular, it is advantageous if the initial region of the positioning elements on the bearing cap, ie the region that first comes into contact with the mating surface on the bearing block, is tapered, whereby the material displacement in the mating surface on the bearing block at the beginning of the tightening of the bearing cap Storage chair can be simplified.
    For the same reasons, it can also be provided that the positioning elements of the bearing cap have an at least approximately triangular cross-section.
    For better absorption of lateral 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 positioning elements.
    Preferably, the further positioning elements are designed to be complementary to the positioning elements of the bearing cap, as a result of which they interact better with the positioning elements on the bearing cap.
    A further improvement of the tension of the bearing cap with the bearing block can be achieved if at least one additional positioning element is arranged on the horizontal plane surfaces, over which the bearing cap and the bearing block rest against each other.
    For a better understanding of the invention, this will be explained in more detail with reference to the following figures.
    Each shows in a simplified, schematic representation:
    1 shows a cross section through a bearing assembly.
    Fig. 2 is a side view of the bearing cap;
    3 shows a detail of the bearing arrangement in the region of the positioning elements in cross section;
    Fig. 4 is an oblique view of the bearing cap;
    5 shows a detail of a bearing arrangement in the region of the positioning 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 the same 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 arrangement, the recess 9 in the axial direction (direction perpendicular to the plane of the paper) 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 vertically extending bearing cover side walls 12 on the side walls 11 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 formed can, as shown in Fig. 3. A gap width 14 of the spade 13 can be selected from a range of 5 pm to 150 pm.
    As can be seen from FIG. 2, at least one positioning element 15 (bracing elements) 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 bracket 2.
    It should be noted that the two bearing cover side walls 15 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 embodiment of the bearing cap 2, 2 such positioning elements 15 are arranged or formed per bearing cover side wall. However, fewer or more than two such positioning elements 15 can also be arranged or formed, for example three, four, five, etc.
    The two positioning elements 15 per bearing cover side wall 12 are in particular spaced from the axial end faces 16 of the bearing cap 2 and eccentrically arranged at a distance from each other or formed, as shown in FIG. 2 can be seen.
    In the preferred embodiment of the bearing cap 3, the positioning elements 15 are designed as positioning webs projecting beyond the bearing cap side walls 12, as can be seen from FIGS. 3 and 4. However, the positioning elements 15 may also have a different shape, for example, they may be formed as positioning grooves, which are introduced as recesses in the bearing cover side walls 12.
    It is also possible that on the or the bearing cover side walls 12 differently shaped positioning elements 15 are arranged or formed, for example, both positioning webs and positioning grooves.
    The positioning 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 positioning elements 15 extend over only a portion of this Lagerdeckelseitenwandhöhe 17, but in any case the arrangement should be such that the positioning 15 thereby at least over a portion of a side wall height 18 of the side walls 11 of the bearing 2 extend ,
    By the clamping together of the bearing cap 3 with the bearing block 2 via the bolt 8, the positioning elements 15 intersect in the side walls 11 of the
    Bearing 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 repair the sliding bearing 4 can be achieved, so so the bearing cap 3 in the reassembly again the correct position relative to the bearing block. 2 occupies.
    The positioning 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 positioning elements 15 of the bearing block 2 to be at least partially tapered over the longitudinal extent 19, as can be seen from FIG. In particular, a pointing in the direction of the clamping surface 5, lower portion 20 of the positioning elements 15 is formed tapered, for example, formed tapered. It can thus be facilitated the penetration of the positioning elements 15 in the side walls 11 of the bearing block 2 when clamping with the bearing cap 3.
    But it is also possible that the positioning 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 easier penetration into the side surfaces 11 of the bearing block 2, the positioning elements 15 may have an at least approximately triangular cross-section viewed in the direction of their longitudinal extent 19, so that they are thus formed in the manner of cutting edges. By at least approximately is meant that the positioning 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 positioning elements 15 can also have a wave-shaped cross section.
    However, other cross-sectional shapes can also be used for the positioning elements 15, for example diamond-shaped or generally polygonal cross-sections.
    The height 22 is in this case the projection of the positioning elements 15 via the bearing cover side wall 12. The height 22 of the positioning elements 15 may be selected from a range of 5 μm to 3 mm.
    According to another embodiment of the bearing assembly 1, it is possible that the positioning elements 15 are not arranged or formed exclusively on the side walls 11 of the bearing block 2 as in the preceding embodiments exclusively on the bearing cover side walls 12 of the bearing cap 3.
    It is also possible that according to a further embodiment variant of the bearing assembly 1 on the bearing cover side walls 12 of the bearing cap 3 and on the bearing side walls 12 opposite side walls 11 of the bearing block 2 more positioning elements 15 are arranged. These further positioning elements 15 may be complementary to the positioning elements 15 of the bearing cap 3, i. with a cross-sectional shape that is inverse to that of the positioning elements 15 of the bearing cap 3. As a result, the positioning elements 15 of the bearing cap 3 can interact with the further positioning elements 15 of the bearing block 2. For example, the positioning elements 15 of the bearing cap 3 can be designed as positioning webs and the further positioning elements 15 of the bearing block 2 as positioning grooves, the positioning webs 15 of the bearing cap 3 engaging in the positioning grooves of the bearing block 2. Preferably, the other positioning elements 15 of the bearing block 2 are made smaller, so that even in this embodiment, the positioning elements 15 of the bearing cap 3 cut into the material of the bearing block 3.
    In principle, the reverse version of this embodiment is possible, that is, for example, the positioning grooves on the bearing cap 3 and the positioning webs are formed on the bearing block 2.
    It is also possible that the further positioning elements 15 on the bearing block 2 are not arranged with the positioning elements 15 on the bearing cover 3 interacting, but arranged offset to them, so that, for example, both the positioning elements 15 and the other positioning elements 15 in the respective material of other component.
    According to another embodiment of the bearing assembly 1, it is also possible that not only the positioning elements 15 on the bearing cap 3 and optionally the further positioning elements 15 are formed or arranged on the bearing block 2, but that additional positioning elements 15 on the clamping surface 5 of the bearing cap 3 and / or formed on the counter-clamping surface 6 of the bearing block 2. These additional positioning elements 15 may in particular be designed in accordance with 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.
    In the preferred embodiment, the bearing block 2 or the bearing cap 3 or the bearing block 2 and the bearing cap 3 are made of a sintered material as sintered components.
    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.
