Definitions
- the present invention relates to a bearing shell for a bearing made of plastic according to the preamble of claim 1.
- Such a bearing shell is known from DE-GM 297 21 050.
- a bearing shell made of a plastic with a low-friction surface is known to be used, which serves as a sleeve for sealing the bearing element, in particular a ball of a ball joint and a pivot pin.
- the cuff is molded on the subject of this older utility model to the bearing shell, so that, among other things, the assembly is simplified.
- the bearing shell must be manufactured and provided separately from the sleeve.
- the object of the present invention is to achieve a further rationalization in production to enable a bearing shell for a cuffed plastic bearing.
- blow or injection blow part simplifies the manufacture of the unit from the bearing shell and sleeve.
- Fig. 2 is a view according to section A-A of
- FIG. 3 is a view as in FIG. 1, but with a bearing shell with expansion folds according to section B-B of FIG. 2.
- the assembly thus essentially has the shape of a sack or a cassette.
- the bearing shell 1 comprises a sack or cassette-shaped one in the exemplary embodiment as a ball 3 and another bearing part designed as a journal 4.
- a cavity 5 is provided or shaped in the area of the cuff 2, which serves as a lubricant reservoir.
- the bag-like or cassette-shaped unit 1, 2 is preferably provided at its open end with a bead which can engage in a groove in one bearing part, here the bearing pin 4. It can also be secured there by a tension ring or a tension band.
- the bearing shell 1 is preferably designed such that its inner diameter (not shown) is smaller than the outer diameter Dj_ of the associated bearing part, here the ball 3. This results in a firm contact of the bearing shell 1 with the ball 3, which is particularly the case with thin-walled bearing shells 1 is an advantage.
- the blown or injection-blown unit consisting of bearing shell 1 and sleeve 2 consists of an elastomer, in particular a thermoplastic elastomer (TPE).
- TPE thermoplastic elastomer
- An elastomer made of or based on at least one rubber such as nitrile butadiene rubber (NBR), hydrogenated nitrile butadiene rubber (H-NBR), acrylic rubber (ACM), chloroprene rubber (CR), ethylene-propylene-diene rubber (EPDM), is preferably used .
- NBR nitrile butadiene rubber
- H-NBR hydrogenated nitrile butadiene rubber
- ACM acrylic rubber
- CR chloroprene rubber
- EPDM ethylene-propylene-diene rubber
- other plastics made of or based on polyvinyl chloride, polyethylene, polypropylene, polyoxymethylene, polyether ether ketone, polyamide or the like can also advantageously be used successfully.
- the bearing shell 1 can have one or more outward-facing expansion folds 6 on the circumference, which form lubrication grooves 7.
- the expansion folds 6 preferably extend in the direction of a meridian of a ball or inclined to it.
- the lubrication grooves 7 can preferably also be designed as a helix.
- a damping and low-friction sliding shell 8 is advantageously provided between the ball 3 and the bearing shell 1.
- the damping and low-friction sliding shell 8 preferably consists of the plastic polyoxymethylene (POM), whereby this damping and low-friction sliding shell 8 can be slotted.
- This damping and low-friction sliding shell 8 can be produced as a separate component. But it can also be produced together with the bearing shell 1 in one operation.
- the housing 9 surrounding the bearing shell 1 can be designed as a track or guide rod, wherein the housing 9 and the corresponding track or guide rod can be designed in a further operation either by the manufacturer or by the user of the plastic bearing according to the invention and connected to this bearing. This connection can be made by overmolding, pressing, snapping or gluing.
- the unit according to the invention comprising the bearing shell 1 and the sleeve 2 can also be provided in bearing applications other than the ball joint shown, such as, for example, in the case of radial or axial bearings.
