Definitions
- the present invention relates to a combination of a screw or a nut and a washer for Aus ⁇ equal to angular position errors between a bolt or the screw and the workpiece to be fastened thereto.
- German Utility Model 7026707 This German utility model already shows a combination of a Mut ⁇ ter and a washer to compensate for Winkelellagefeh- learning between a bolt and the workpiece to be attached thereto, the mother on her the washer facing zuge ⁇ face is convex.
- the applied to the mother surface of the associated washer was kegelför ⁇ mig configured.
- the spherical surface of the nut according to this prior art always only rests along a circular line on the cone-shaped mating surface of the washer.
- high pressures occur here, which in turn leads to deformation of the surfaces, thus to a high setting and the associated preload force loss of the connection to lead.
- the high surface pressure can also ske ⁇ when tightening the connection for "eating" between the two parts.
- DE 10136829 C1 discloses a very complicated configuration for solving this problem, in which, however, the washer is convex and the associated face of the nut is concave, which likewise leads to a linear contact between nut and washer.
- the mother still has a funnel-shaped approach to hold the washer.
- this construction is very complicated and therefore hardly practicable.
- the disadvantages due to the linear contact between the parts described with reference to Utility Model 7026707 also apply to this solution.
- this object is achieved with a combination of screw or nut and washer, in which both the washer on its the nut or the screw head facing surface, and the nut or screw on the washer, concave is formed.
- the nut or screw head and washer additionally act like a ball joint and the washer becomes, despite a slight tilt of the bolt or the screw relative to the perpendicular to the component surface ⁇
- the spherical cap shape of the nut or of the underside of the screw head has the same radius as the spherical cap shape of the washer. Then mother and washer always touch on the entire surface, whereby the load on the surfaces of mother ter and washers is reduced.
- the disadvantages of the prior art according to DE 7026707 are thus clearly avoided even with large loads on the connection.
- the nut is provided on the side facing the washer with a hollow cylindrical projection extending in the direction of the bolt, which extends through the inner opening of the washer, and whose inner diameter is significantly greater than the outer diameter of the thread of the bolt and whose Au ⁇ ° mismesser is smaller than the inner diameter of the Mit ⁇ telloch of the washer and the washer is crimped by means of this approach to the body of the mother.
- the washer is held captive on the mother, whereby the storage and installation is simplified.
- the washer is provided with a slot. As a result, an even larger angular position error of up to +/- 5 degrees can be compensated.
- the washer can be captive ange ⁇ attached to the screw, which offers significant advantages in processing.
- Figure 1 is a sectional view taken along the central axis of the nut and shim according to the invention
- FIG. 1 shows the detail B of Figure 1
- FIG. 3 shows the combination of nut and disc from above
- FIG. 4 shows a screw-washer combination according to the invention from the side, wherein the washer is shown in section;
- Figure 5 shows the combination of Figure 4 from above.
- FIG. 6 the angle compensation option in the embodiment according to FIG. 4.
- FIG. 1 shows a nut 10 according to the invention with a washer 12 according to the invention.
- the actual core of the invention lies in the detail B, which is shown considerably enlarged in FIG. The further description therefore follows from FIG. 2.
- the nut 10 is formed in the shape of a spherical cap at its end face 14 facing the washer.
- the washer 12 in contrast, has on its surface facing the nut a corresponding spherical cap-shaped recess, that is to say a negative spherical cap-shaped surface 16. Furthermore, the washer according to the invention, as usual, has a central opening 18. This normally serves to pass through the bolt, but here it is expanded according to the invention in such a way that it can additionally accommodate a hollow cylindrical projection 20 of the nut 10.
- the outer diameter of the lug 20 is smaller than the inner diameter of the center hole 18 of the washer 12.
- the lug 20 has an inner diameter that is considerably larger than the outer diameter of the thread of the bolt 20, the washer 12 is held captive but movable on the nut 10.
- FIG. 3 shows an illustration of the nut-disc combination on the view of the drive of the nut.
- FIG. 4 shows a further embodiment of the invention in which a suitably configured combination of screw and washer reaches the insert.
- the screw 100 here consists of a head 102, on which a corresponding force attack (external hexagon, as shown here, or any other possible force application) is arranged, and a shaft 104 with a diameter D, to which, according to Auf ⁇ set a washer 112, a thread 106 has been rolled with theêt ⁇ diameter M.
- the underside of the screw head 102 is convex here, preferably formed spherical cap.
- This head bottom side 114 rests on a counter-surface 116 of the washer 112, which is concavely curved and preferably has a negative spherical cap.
- the radii of the two spherical caps are the same.
- the washer 112 is preferably provided with a slot 118 whose smallest diameter is larger than the diameter D of the unalloyed shaft 104 but smaller than the outside diameter M of the rolled thread 106, so that the Washer 112 is held unverlier ⁇ bar after rolling of the thread 106 on the screw 100.
- FIG. 5 shows the position and design of the oblong hole 118 in an interrupted representation under the screw head 102 shown in solid line.
- FIG. 6 shows the angular tolerance compensation of up to +/- 5 degrees possible with this embodiment according to the invention.
