    • 专利摘要:
    The crankshaft bearing uses various guide surfaces on the casing and cap to center and guide the cap into place in the casing. The guide surfaces are formed by a single machining step and are subdivided into separate portions. The studs which secure the cap to the casing each have a centering collar which is received in a bore of the cap to aid the centering of the cap during assembly.

    (5+) NATURAL BEARING OF CRANKSHAFT
    Iso-current relates to mechanical engineering and can be used in reciprocating internal combustion engines.
    A crankshaft main bearing is known for an internal combustion engine, comprising a housing with a recess and a removable one installed with pins and mating with it along the junction and two heating surfaces, each guide surface of the recess and the cover being divided. on. two areas, one of which is located at the ends of the recess and near to the junction, 18 covers, and the other t on the ends of the notch and cover l removed from the junction.
    A disadvantage of the known device is that the portions of the guiding surfaces are located in a section; 20 planes, which complicates the manufacture of the bearing. In addition, such an arrangement makes the mounting of the bearing more difficult, since, due to the small distance of the reversed 25
    towards the junction of surfaces, the lid should move in two directions: first, parallel to the axis of the shaft journal, and then perpendicular to it.
    The purpose of the invention is to simplify the manufacture and installation of the bearing.
     The goal is achieved by the fact that both sections of the guide surfaces of the recess and the cover are located in the same plane, the section of the guide surface located at the end of the cover close to the junction is made wider than the axial width of the cover, and the section of the guide Surface located at the end of the recess remote from the junction is provided with a groove located in the middle part of its axial width, the width of which is greater than the width of the section of the guide surface located in the near , To the joint end of the cover, the distance between the upper edge portion of the cover guide surfaces
    can be made smaller than the distance between the lower edges of the sections of the guide surfaces of the recess, and the pins can be provided with centering shoulders, the distance from which to the joint is greater than the distance from the joint to the lower edge of the section of the guide surface located on near the joint end of the notch.
    FIG. 1 shows the main bearing, cross section; Fig.2First position of the cover when mounting the bearing; Fig. 3 - view A,. in figure 2; in fig. - view In figure 2; on . FIG. 5 is a section from CC to FIG. 2; in fig. 6 - the second position of the cover when mounting the bearing; in fig. 7 is a section DD-D in FIG. 6; in fig. 8 is a section E-E of FIG. 6
    The main bearing contains a core 1 with a notch 2 and a removable cover 3, mounted to the notch 2 by means of pins A and adjacent to it along the junction 5 and two guide surfaces, each guide surface of the notch 3 being divided into section 6, located at the end of the recess 2 closest to the junction 5 and to the section 7, located at the end of the recess remote from the butt 5. from the junction 2 of the end of the cover 3, both portions 6,7. and 8.9 of each guide surface are located in one plane. The section 8 of the guide surface of the cover 3 is made along the width smaller than the axial width of the cover 3 itself and is located in its middle part, and the section 7 of the notch 2 has a groove 10 which is wider than the width section 8. Moreover, the distance between the upper edge 11 of section 8 and the upper edge 12 of section 9 of the guide surface of the cover 3 is smaller than the distance between the lower edge 13 of section 6 and the lower edge of the section 7 of the guide surface of the notch 2. Pins k stocked with a cent Boring flanges 15, the distance from which are extended to junction 5 is greater than the distance from junction 5 to the lower edge 13 of section 6 of the guide surface of the recess 2
    When mounting the lid 3, it is centered in the recess 2 first with the centering shoulders 15 of the pins k, with further upward movement of the lid 3 upwards - by sections 6 and 8 of the guides 7 and 9, and then by sections 6 and B of the guide surfaces of the notch 2 and the cover 3

    Invention Formula
    A crankshaft main bearing, in particular for internal combustion engines, comprising a housing with a recess and a removable cover installed in the recess by means of pins and interfaced with it along the junction and two guide surfaces, each recess surface and the cover is divided into two sections, one of which is located at the ends of the recess and cover nearest to the junction, and the other at the end of the notch and cover remote from the junction, characterized in that, in order to simplify its manufacture and installation, both sections of the guides The surfaces of the recess and the cover are located in the same plane, the section of the guide surface located at the end of the cover near the junction is smaller in width than the axial width of the cover and placed in its middle part, and the section of the guide surface located at the remote from the junction the end of the recess is provided with a groove placed in the middle part of its axial width, the width of which is wider than the width of the section. on the near-to-butt end of the cover.
    [2]
    2. The bearing according to claim 1, wherein the distance between the upper edges of the portions of the cover guiding surfaces is less than the distance between the lower edges of the portions of the guide surfaces of the recess.
    [3]
    3. Bearing on PP. 1. And 2, which is distinguished by the fact that the pins are provided with centering shoulders, the distance from which to the joint is greater than the distance from the joint
    to the lower edge of the portion of the guide surface located at the end of the recess near the junction. 5 Sources of information
