Definitions
- the present invention relates to a self-locking nut, which is also referred to as a "clamping nut”, with a core hole and thread grooves.
- this object is achieved by a self-locking nut or clamping nut which has a core hole with a reduced inside diameter in one or more areas.
- the areas between the thread grooves in one or more parts of the internal thread can not be flattened, but can be formed in a pointed ridge which protrudes beyond the remaining internal thread.
- Such a clamping nut according to the invention has the following advantages: The manufacturing costs are lower and can correspond to the production costs of a standard nut without clamping or self-locking effect, since no additional material and no additional processing step is necessary to achieve the clamping effect.
- the clamping effect can be co-produced according to the invention during cold working or during thread cutting.
- Nuts according to the invention weigh less and have a lower overall height than tapered clamping nuts. As a result, they do not require so long screws or bolts and no extra space in the application.
- the clamping nuts according to the invention also have a much better clamping action, since the clamping does not act diagonally, and finally the self-locking nuts according to the invention have little or no tendency to seizure.
- the areas of reduced core hole inner diameter each extend over only a small portion of the circumference of the core hole of preferably 10 to 15 degrees. In this way, a seizure of the screw connection is prevented, although still a sufficiently high clamping effect can be achieved.
- the areas with reduced core hole diameter only in the three to four last, that is remote from the screw side of the nut threads of the internal thread. The nut then only clamps when it is screwed almost completely onto the screw or the bolt.
- the areas of reduced core hole diameter may preferably be formed by flat portions on the inner diameter of the core hole.
- the nut according to the invention is particularly easy to produce, since the core hole is usually produced today by pressing and only at the remote from the workpiece end of the nut a ram with corresponding flats must be used. Apart from the one-time conversion of the tool, so the stamp, then incurred no further costs in the production of the mother of the invention.
- the areas formed as a sharp ridge extend only over a small portion of the circumference of the internal thread, since this can further reduce the tendency to seizure.
- the formed as a sharp ridge areas extend only between the three to four last, that is remote from the workpiece side of the nut thread furrows of the internal thread. In this way, the mother only clamps when it has been screwed sufficiently far on the bolt.
- Figure 1 is a sectional view of a clamping nut according to the invention.
- FIG. 2 shows the clamping nut of FIG. 1 from above
- Figure 4 shows the clamping nut of Figure 1 from above with screwed and cut at height of the nut nut;
- FIG. 5 shows the illustration of FIG. 3 with the bolt inserted
- FIG. 6 shows the detail X of FIG. 5.
- Figure 1 shows a clamping nut according to the invention or self-locking nut 10 from the side in a sectional view.
- the internal thread 12 is not shown in greater detail in accordance with the usual drawing standards. Shown are those areas 14 in which the core hole diameter is reduced, or increased burrs are provided between the thread grooves. As shown, these areas 14 extend over almost half the length of the internal thread of the nut 10, these are usually three to four threads.
- FIG. 2 shows the mother of Figure 1 from above, again the internal thread 12 and the areas 14 can be seen with reduced core hole diameter or raised burrs between the thread grooves.
- FIG. 2 it can be seen very clearly that in the present embodiment there are three areas 14 with reduced core hole diameters or raised burrs between the thread grooves, which are distributed equally spaced over the thread turn, so that the distance between the individual areas 14 is 120 degrees.
- FIG. 3 shows the nut of FIG. 1 partially cut along the line A-A of FIG. 4 with a detailed representation of the internal thread 12.
- the area 14 on the top right in the image can already be seen very well with the differently shaped thread according to the invention
- a conventional internal thread 12 is shown in the lower part of the illustrated nut 10. This consists, as usual, of V-shaped grooves 16 between which flattened portions 18 extend, which abut geo-metrically on the lateral surface of a cylinder with the core hole diameter.
- flanks 19 of the V-shaped grooves 16 are extended and meet in a pointed ridge 20, which therefore projects into an imaginary cylinder with the core hole diameter.
- Figure 4 shows the clamping nut according to the invention or self-locking nut 10, in which case a bolt 100 is screwed, which is shown cut at the height of the upper end of the nut 10. Again, the areas 14 with the reduced core hole diameter are clearly visible again. Here is also very well recognizable, as in the area 14, the core hole diameter of bolt 100 and nut 10 coincide, whereby the present invention desired clamping effect is brought about.
- FIG. 5 likewise shows the combination of nut 10 and bolt 100 shown in FIG. 4, wherein the nut 10 is again shown partially cut along the lines A-A of FIG. 4 as in FIG.
- the bolt 100 is not shown cut for clarity, so you can see the external thread 102 of the bolt well.
- the bolt 100 may be commercially available and comply with the usual technical standards.
- the inventive meshing of the external thread 102 of the commercial bolt 100 with the inventively modified region 14 of the internal thread 12 of the nut 10 is shown in more detail than detail X in Figure 6.
- the internal thread 102 of the bolt 100 is shown cut to better illustrate the clamping action of the invention.
- the region of the internal thread 12 of the nut 10 is shown, which is normal, that is formed according to the prior art, so that the difference to the inventive design of regions 14 of the internal thread 12 emerges even more clearly.
- the lower two threads of the internal thread 12 of the nut 10 in Fig. 6 are normally formed according to the prior art, while the upper three threads shown in Fig. 6 have a reduced core hole diameter.
- the flanks 19 of the V-shaped thread grooves 16 normally terminate in a flattened region 18 which separates the individual thread grooves 16 and whose surface corresponds to the surface area of a cylinder having the standard core hole diameter. In this way, over the entire length of thread required for low-friction screwing of the bolt 100 in the nut 10 game 22 is guaranteed. Only when a biasing force between bolt 100 and nut 10 acts normally flanks 19 of the nut thread against the opposite flanks of the bolt are pressed in not self-locking nuts, and by the thereby triggered friction holds the screw.
- the plateau-like region 18 is missing between the individual threads 16 of the internal thread 12 of the nut 10. Instead, the flanks 19 of the individual thread grooves 16 in this region 14 pass over only a very large part small radius into each other, whereby protruding ridges 20 are formed between the thread grooves 16.
- FIG. 6 shows the theoretical geometric relationships.
- the black area of the ridges 20 shown is actually not present, but in this area the ridges 20 are elastically deformed by the contact pressure to the valley bottom of the grooves 116 of the bolt 100.
- the burrs 20 are actually somewhat “flattened” while penetrating into the bottom of the grooves 116 of the external thread of the bolt 100 at the same time. Since this effect occurs from several sides simultaneously, a clamping of the screw and thus a self-assurance is achieved, regardless of whether a biasing force has already occurred during screwing, or not.
- two or more, preferably three uniformly spaced regions 14 are provided according to the invention over the circumference of the internal thread 12 of the nut 10.
- the regions 14 can be manufactured in different ways:
- nuts are usually manufactured today by cold forming, stamping punches with the core hole diameter from above and below, and then cutting, rolling or rolling the thread.
- the punch diameter can be selected to be somewhat smaller, since with a chipless production of the internal thread 12 of the nut 10, the material displaced by the formation of the thread grooves 16 is displaced into the regions 18 between the thread grooves.
- the regions 14 can now be produced simply by grinding or hollowing out these regions on the stamp which acts on the mother from above. In this way, either a secant-shaped, ie flat region 14 can be produced, or what is still preferred according to the invention and also shown here, an inwardly curved region 14. This inward curvature is particularly preferred in order to seize the thread in the clamping state avoid.
- the curvature is defined with a large radius from the outside.
- the regions 14 can be produced in non-cutting production of the internal thread 12 by making the thread grooves 16 of the internal thread 12 deeper and / or wider in the region 14, whereby more material is deformed and correspondingly higher burrs are raised between the individual threads become.
- the production of a clamping nut according to the invention is not complicated or complicated than the production of a commercial-usual mother without clamping action. Only the manufacturing tools, so either the punch for the production of the core hole or the tools for thread rolling or thread rolling, must be performed once differently.
