- the bearing body is still pivotable over its entire pivoting angle relative to the bearing housing without damaging the spring tongues or pinching them between the mounted component and the bearing housing is afraid.
- the bearing body regions having a larger radius have axially outward positions relative to bearing body regions may be arranged smaller radius, the spring tongues are preferably not from the spherical envelope of the bearing body region with the largest radius.
- the joint bearing according to the invention can be used for the storage of rotating shafts or for the storage of axially displaceable in the receptacle components such. B. push rods serve.
- the joint bearing according to the invention has proven to be suitable for the storage of car pedals.
- the invention thus also encompasses a spherical plain bearing with a component mounted in the receptacle, in particular an automobile pedal, wherein several or all spring tongues rest without play and preferably under prestress against the component to be supported.
- the spring tongues end at the level of the front side of the dome-shaped bearing body or within the same. Damage to the spring tongues, even under unfavorable environmental conditions, is thereby largely avoided, and the spherical plain bearing can also be used without restriction of the installation space, which is particularly advantageous in tight spaces.
- recesses are provided radially outwardly to the spring tongues in the bearing body, which can accommodate at least partially or completely in the radial direction when the component to be supported on the bearing surface of federal government or the plurality of circumferentially spaced projections at the level of the respective spring tongue ,
- the spring tongues can avoid a play between the receptacle and the component to be supported and ensure a "soft" or elastic mounting of the respective component
- the mounted component is preferably always load-bearing on the bearing surface of the federal government or the recording limiting projections can be applied, so that the bearing body can absorb high forces and have a long service life.
- the recess is designed in each case as circumferentially completely encircling annular channel, so that all of the arranged on one side of the respective central main plane of the bearing body spring tongues can be at least partially or preferably completely absorbed by the annular channel with a corresponding force of the component to be supported on the respective spring tongues.
- This embodiment is easy to manufacture and, furthermore, foreign substances accumulating radially outwardly of the respective spring tongue can easily be removed through the annular channel.
- only partially circumferential circumferential channels can be provided, which extend in the circumferential direction over at least two spring tongues or each may be formed semicircular. Any separation between the partially circumferential channels is preferably provided in the 12 o'clock or ⁇ o'clock position of the respective bearing body in its neutral position in the installed position.
- the respective spring tongues are preferably formed directly on the collar or the plurality of radially spaced projections defining the receptacle for the component to be stored, each of which provide the bearing surface, and preferably terminate flush with the respective radially inner bearing surface.
- the spring tongues may extend in the axial direction of the bearing body.
- the length of the spring tongues in the axial direction less than the axial extent of the collar or the plurality of circumferentially spaced projections defining the receptacle for the component to be stored.
- the length of the projections may be approximately between approximately 50% and approximately 100% of the axial length of the collar or of the projections mentioned.
- the axially free ends of the spring tongue can each be provided with a chamfer to facilitate the introduction of the component to be stored in the recording.
- bearing housing and / or the bearing body are made in one piece.
- Bearing housing and / or bearing body may be made of plastic, in particular as an injection molded part.
- the bearing housing may also be designed in several parts, for example in the form of two half-shells.
- the spherical plain bearing can be produced in such a way that the calotte-shaped bearing body is locked to the preferably one-part bearing housing or that a multi-part bearing housing, eg. B. is provided in the form of two half-shells.
- bearing body and bearing housing are produced in an extrusion coating process, so that the bearing housing serves as a mold for the production of the dome-shaped bearing body or vice versa, the dome-shaped bearing body as a shape for the bearing housing in the injection molding production process.
- FIG. 2 shows a sectional illustration of the bearing body according to FIG. 1 along the line AA
- Figure 3 is a sectional view of the bearing body of Figure 1 along the line BB.
- the joint bearing 1 has at least one one-piece bearing housing 2 with a dome-shaped bearing body 3, which is received by a bearing cup 2a and having a receptacle 4 for a component to be stored.
- the receptacle 4 is in this case designed as a passage opening, which has a cylindrical shape, but in general can be adapted in its shape to the outer contour of the component to be supported.
- the width of the receptacle of the bearing body is performed by a circumferentially circumferential collar 5, which has a cylindrical inner surface as a bearing surface to which the component to be stored (not shown) can be applied load-bearing, so that the forces can ultimately be transferred to the bearing housing ,
- the bearing body is freely pivotable about a pivot point 6 and is received in a freely rotatable manner about the bearing housing 2 about a central axis 7 containing the pivot point.
- the recorded by the bearing body 3 component can be pivoted in a solid angle.
- spring tongues 8 are provided which extend in the axial direction of the bearing body 3 and the recording by means of the radially inward
- the diameter of the receptacle of the height of opposite projections 9 is thus slightly smaller than the diameter of the collar 5 at the level of the said projections
- the narrowing of the receptacle by the spring tongues can be in the range of 0.2 mm to 1 mm, for example in the 0.5 mm, which may apply independently of the exemplary embodiment
- the bearing body can by means of the spring tongues 8 without play on the mounted component
- some or all of the spring tongues 8 are elastically prestressed in order to ensure a "soft" mounting of the respective component ..
- Spring tongues are also arranged within the spherical envelope 3a of the bearing body cap or close with their free ends 8a at the height of the The front side of the bearing body 3 from, so that a pivoting of the calotte is not hindered and damage to the spring tongues is avoided.
- the recesses are formed according to the embodiment as in each case fully circumferential annular channel 10, which has a constant cross-section over its circumference, but this is not absolutely necessary.
- the annular channel 10 is open at the front, more precisely, the radially outer and / or inner walls of the annular channel (the latter correspond to the radially outer sides of the spring tongues) are substantially or exactly parallel to the axis 7 of the bearing body.
- the radial width of the annular channel is in this case several times greater than the height at which the projections 9 project beyond the collar 5 into the receptacle.
- the radial width of the annular channel may be approximately equal to or greater than the radial thickness of the spring tongues at the level of the federal government or the bearing these areas of the bearing body.
- annular channel 10 is provided on both sides of the collar 5 or correspondingly spaced-apart projections for supporting the respective component.
- the bearing body is symmetrical to the central main plane 11 educated .
- the spring tongues 8 are further formed directly on the collar, more precisely, they are flush with the inwardly directed bearing surface of the collar 5, so that is provided at load-bearing contact of the respective component on the collar and spring tongues and a continuous contact surface.
- the spring tongues extend in the axial direction of the bearing body.
- the length of the spring tongues 8 in the axial direction is less than the axial extent of the federal government.
