DE2412870A1 - Plain bearing halves with flanges - are mounted with lugs and are machined after assembly - Google Patents

Abstract

The thin bearing scales are provided with cut-outs at each end. Half flanges with internal lugs are mounted at either side of the bearing scales. The sides of the cut-outs are peened over, so that the lugs of the scales are trapped and the flanges are fixed in position. The inside edges of the flanges are sharp before they are assembled. After assembly of the flanges, two bearing halves are placed together to form a complete bearing. The edges, which includes the lugs and peened over cut-outs are now machined to give the bearings a rounded edge.

Description

with flanged bearing half The invention relates to a with Flanged bearing half with a thin-walled, flexible bearing half-shell and one on at least one end face of the bearing half-shell radially outwards extending SlanBch, which is axially movable and tiltable on the bearing half-shell and is arranged in such a way that the bearing halves are deformed during installation can, wherein the end portions of the bearing half-shell beveled on the inner peripheral edge are according to the main patent (patent application P 21 40 845.7-12).

In the case of the bearing half-shells described in the main patent inner peripheral edge beveled on the face of the bearing half-shell and the flange also has a beveled inner peripheral edge and is attached to the face of the bearing half-shell.

The bevels of the bearing half-shell and the flange complement each other in the assembled state to a uniform inner slope is supported on the crankshaft journal, while the flanges on the crank web issue. A rounding is provided at the transition from the crank web to the crank pin, and the chamfer on the bearing shell and the flange forms together with the fillet a gap.

The object of the present invention is now the bearing half-shell better to design together with the flange in this area.

In the case of the bearing half explained in more detail at the beginning, this is according to the invention achieved in that the end portions of the bearing half-shells on the inner peripheral edge - viewed in longitudinal section - have a curved profile.

The curved profile is advantageously on both end faces the bearing shell and arranged on the inner circumferential edge of the flange0 tears Flange on its inner circumference at a distance from one another several projections, those with a corresponding number of slots on the face of the bearing half-shell are in engagement, the curved profile is also formed on the projections.

In the drawing, an embodiment of the invention is shown, which is explained in more detail with reference to the following description. It shows: Fig. 1 the overall arrangement of the bearing half-shell and flange, disassembled and in perspective view, FIG. 2 shows a detailed view of the connection between the flange and bearing half-shell and FIG. 3 shows a further detailed view of the connection between Flange and bearing half-shell in perspective view.

According to Sig. 1, a bearing half-shell 10 has three slots 11 which are provided on the two end faces of the bearing shell 10. Pressure flanges 12 for attachment to the bearing half-shell 10 are with inwardly extending Projections 13 provided with the corresponding slots 11 of the bearing half-shell 10 can be engaged.

Before attaching the flanges 12 to the bearing half-shell 10, have the inner peripheral edge of the flanges 12 and the end sections of the bearing half-shells 10 a substantially rectangular cross-section 0 The flanges 12 are attached to the Arranged end faces of the Bager half-shell 10, the projections 13 in the slots 11 can be inserted. The outer free corners of the slots 11 are then like 2 can be seen deformed and form projecting stops 14 which form the flanges 12 on the bearing half-shell 10.

The projections 13 sit with enough play in the slots 11 to a radial bending of the bearing half-shell 10 with respect to the flange 12 and a To allow limited axial play of the flanges 12 with respect to the bearing half-shell 10.

Two such storage aids then become a complete warehouse Assembled and cutting tools are simultaneously on both sides of the warehouse moved towards this in the opposite direction to form a curved profile 15 - see Fig. 3 - on the inner peripheral edges of the bearing half-shell 10, the inner Form peripheral edges of the flanges 12 and the projections 13.

Although part of the projecting stops during this machining 14 is removed, one of the protruding stops 14 remains a sufficient one Part stand in order to fix the flanges 12 to the bearing half-shells 10. In Fig. 3, the dash-dotted lines show the dimensions of a plan 12 and the Bearing half shell 10 before processing in the tool machine. The corners of the The bearings can be adapted to the fillets between the crankshaft journals and the crankshaft webs are provided on which the bearings are arranged rollo Regarding more details of the bearing shell, its manufacture and its Installation is referred to the main patent (patentanneldur.g P 21 40 845.7-123 The deviation described in the main patent is according to the invention duroh a curved Replaced profile with a certain radius.
