Definitions

  • the invention relates to a spherical plain bearing according to the preamble of claim 1.
  • elbow bearings mostly consist of roller bearing steel, with the inner and outer body being machined. This method of production is time and energy consuming. In addition, such elbow bearings have a relatively high weight because of the large mass of the outer body. Spherical plain bearings made of bearing steel also have to be subjected to anti-corrosion treatment, which is complex and polluting. The use of stainless steel is only possible in exceptional cases due to the high costs.
  • a spherical plain bearing is known, the outer body of which consists of two thin-walled, chipless-shaped sheet metal half-shells, which are separated from one another by a joint running transversely to the bearing axis and are surrounded by a sheet metal sleeve and whose inner surfaces form the bearing surfaces for the inner body. Complicated sheet metal forming steps are required to produce such an outer body.
  • the outer body can be made with simple tools made of steel strip of any quality can be produced, and due to the low mass, more expensive materials, such as IMiro steel, can be used without excessively increasing the costs.
  • the construction of the outer body from only two geometrically very simple parts means that the machine park required for production is small; because essentially only punching tools and deep-drawing tools are required for the production of the parts and a device for connecting the parts to one another. In principle, however, the parts of the outer body can also be automatic turned parts.
  • the outer body preferably consists of two deep-drawn tin pots which are plugged into one another and firmly connected to one another, the bottoms of which are provided with circular openings.
  • the two parts forming the outer body are automatically centered and the distortion-free connection of these parts is also facilitated.
  • the peripheral wall and / or the bottom of the inner pot can be provided with cutouts. This results in a positive connection of the plastic filling with the outer body through the plastic penetrating into the recesses or recesses or through the protrusion of the elevations into the injected and hardened plastic.
  • a method according to the invention for producing such a spherical plain bearing is the subject of claim 10. As can be seen, the spherical plain bearing according to the invention can be manufactured with extremely simple method steps using simple machines. Embodiments of the invention are described below with reference to the drawings. It shows:
  • FIG. 6 shows a front view of the inner pot similar to FIG. 5, but with the plastic filling in a first modification
  • FIG. 7 shows a front view of the inner pot similar to FIG. 5 in a second modification
  • FIG. 6 shows a longitudinal section similar to FIG. 1 of a spherical plain bearing with a bearing material support on the inner body
  • FIGS. 9 to 12 show different modifications of the outer body consisting of two parts in longitudinal section.
  • the spherical bearing shown in Fig. 1 has an outer body 1, in which a spherical inner body 2 is rotatably and pivotally mounted.
  • the outer body is formed by two tin pots 3 and 4, which are inserted into one another and rest against one another with their peripheral walls.
  • Bottoms 5, 6 of the pots 3, 4 are provided with circular central openings 7, 8, the edges of which are shaped in accordance with the spherical curvature of the outer surface of the inner body 2 and serve as centering surfaces for the inner body.
  • the space between the inner surface of the inner pot 4 and the outer surface of the inner body 2 is filled with a plastic mass 9 which has sliding properties.
  • the pots 3 and 4 are produced by first blank blanks with central openings being punched out of a thin sheet metal strip. These circular blanks are then formed into pots 3, 4 in a deep-drawing process, the edges of openings 7 and 8 simultaneously receiving their shape. After inserting the inner body 2 into the outer pot 3, the inner pot 4 is pushed into the outer pot 3, the inner body 2 being centered by the edges 7, 8.
  • plastic is injected in a conventional manner through openings, not shown, into the space between the outer and the inner body.
  • an anti-rotation device is provided see, which is designed so that it is formed during the deep drawing of the inner pot 4, so that ksin additional operation is required.
  • the anti-rotation lock can have different shapes.
  • at least one elevation 13 or a polygon 14 is formed on the inner circumferential surface 12 of the inner pot 4, against which the solidified plastic can be supported in the circumferential direction.
  • the peripheral wall 15 of the inner pot 4 is provided with rib-shaped projections 16 or 17 and in FIG.
  • the exemplary embodiment according to FIG. 8 differs from that according to FIG. 1 in principle only in that on the outer surface of the inner body 2 there is a precisely molded, pre-tensioned, maintenance-free bearing shell 21 is arranged, for example, from a wire mesh made of bronze impregnated with PTFE. The space between this bearing shell and the inner peripheral surface of the inner pot 4 is filled with plastic compound 9, as in the example of FIG. 1.
  • FIG. 10 differs from that of FIG. 9 only in that the pots
  • the outer body 1 is formed from a pot 24 and a lid 25 det, which are welded together and in turn are provided with circular openings 7,8.
  • the cover 25 can be planar as in FIG. 11 or cranked outwards as in FIG. 12 in the central area provided with the opening 8.
  • the parts 22, 23 or 24, 25 of the outer body 1 'or 1 "from FIGS. 10 to 12 can be produced from sheet metal using the deep-drawing or stamping process or else on automatic lathes.
