Plougmann & Vingtoft Patentbureau. _'_ ‘ (54) Møtrik eller anden med gevindhul forsynet genstand og fremgangsmåde til fremstilling af denne.Plougmann & Vingtoft Patent Office. (54) Nut or other threaded article and method of manufacture thereof.

Opfindelsen angår en møtrik eller anden med gevindhul forsynet genstand.The invention relates to a nut or other threaded object.

Der findes et meget stort antal forskellige gevindtyper, der afviger fra hinanden bl.a. med hensyn til stigning, flankeform etc. Som eksempler på anvendte gevindtyper kan nævnes metrisk gevind, tomme-gevind eller Whitworth-gevind, A.S.M.E.-gevind, B.A.-gevind, B.S.F.--gevind, Lowenherz-gevind, S.A.E.-gevind, U.S.St.-gevind, C.E.I.--gevind. Af disse gevindtyper er metrisk gevind det mest anvendte i f.eks. Tyskland, og tommegevind eller Whitworth-gevind er det mest anvendte i England og U.S.A., medens man i Skandinavien i vid udstrækning anvender begge disse gevindtyper. Anvendelsen af disse forskel- 2 141181 lige gevindtyper betyder, at en fabrikant, der fremstiller en genstand, i hvilken der indgår en møtrik eller et gevindhul, som skal samarbejde med en skrue, må fremstille genstanden i mindst to udgaver, hvis den skal sælges såvel på det amerikanske som på det europæiske marked. Det er klart, at en sådan fremstilling og lagerføring af genstanden i to udgaver dels virker omkostningsforøgende og dels indebærer risiko for fejlleveringer. I de tilfælde, hvor fabrikanten af genstanden også leverer den til genstanden hørende skrue, må han også lagerføre to skruetyper, som endog i visse tilfælde hver især må forefindes i flere længder.There are a very large number of different thread types that differ from one another. with regard to pitch, flank shape, etc. Examples of thread types used include metric thread, inch thread or Whitworth thread, ASME thread, BA thread, BSF thread, Lowenherz thread, SAE thread, USSt. - found, CEI - found. Of these thread types, metric thread is the most widely used in e.g. Germany, and thumb or Whitworth threads are the most widely used in England and the U.S.A., while in Scandinavia, both of these thread types are widely used. The use of these different thread types means that a manufacturer manufacturing an article which includes a nut or threaded hole to cooperate with a screw must produce the article in at least two versions if it is to be sold as well in the US as in the European market. It is clear that such manufacture and storage of the item in two versions partly increases the cost and partly involves the risk of incorrect deliveries. In cases where the manufacturer of the article also supplies the screw belonging to the article, he must also stock two types of screw, which even in certain cases each must be provided for several lengths.

Disse ulemper har man hidtil anset for at være uundgåelige onder, indtil der måtte blive opnået en international standardisering af gevind, og indtil en sådan eventuel standardisering er blevet taget til følge i de forskellige landes erhvervsliv, hvilket erfaringsmæssigt tager adskillige år.These disadvantages have hitherto been considered to be unavoidable evils until international standardization of threads has been achieved, and until such standardization has been adopted in the business world of the various countries, which in experience takes several years.

Ved den foreliggende opfindelse er det imidlertid gjort muligt at undgå de ovennævnte ulemper, der hidrører fra benyttelsen af forskellige gevindtyper, og møtrikken eller genstanden ifølge opfindelsen er ejendommelig ved, at der i gevindhullet er udformet mindst to hinanden overlejrende gevindtyper. Det har overraskende vist sig, at det er muligt i samme borede hul at udforme mindst to gevindtyper, hvis gevinddiameter nogenlunde svarer til hinanden, og at forskellige skruer, der hver især har en af disse forskellige gevindtyper, alle uden vanskeligheder kan samarbejde med et sådant gevindhul.However, in the present invention it has been made possible to avoid the aforementioned disadvantages arising from the use of different thread types, and the nut or article of the invention is characterized in that at least two superimposed thread types are formed in the thread hole. Surprisingly, it has been found that it is possible in the same drilled hole to design at least two thread types, the thread diameters of which are roughly the same, and that different screws, each having one of these different thread types, can all cooperate with such difficulty without difficulty. threaded hole.

Normalt regner man med, at højden af en møtrik og længden eller dybden af et gevindhul nogenlunde skal svare til diameteren for det anvendte gevind. Når der i ét og samme gevindhul i overensstemmelse med opfindelsen anvendes mindst to gevindtyper, vil gevindene i gevindhullet hver især blive noget svækket, hvorfor gevindhullets længde normalt bør være væsentligt større end gevinddiameteren. Hvis der således i et gevindhul anvendes to forskellige gevindtyper, f.eks. metrisk gevind og tommegevind, vil det normalt være passende at lade gevindhullets længde svare nogenlunde til den dobbelte gevinddiameter. Styrkeforsøg har vist, at der da gennem gevindene vil kunne overføres en kraft, der er større end den, der kan overføres gennem den tilhørende skrue.Usually, the height of a nut and the length or depth of a threaded hole are expected to roughly correspond to the diameter of the thread used. When at least two thread types are used in one and the same thread hole in accordance with the invention, the threads in the thread hole will each be somewhat weakened, so the length of the thread hole should normally be substantially greater than the thread diameter. Thus, if two thread types are used in a threaded hole, e.g. metric thread and inch thread, it will usually be appropriate to allow the thread hole length to correspond roughly to the double thread diameter. Strength tests have shown that, through the threads, a force greater than that transmitted through the associated screw can be transmitted.

141181 3 Når der i gevindhullet udformes to forskellige gevindtyper, kan det være fordelagtigt at vælge gevind, hvis tilsvarende borehulsdiametre er lidt forskellige. Man fremstiller da først på normal måde et gevindhul med det gevind, der har den mindste tilhørende borehulsdiameter, og derefter udformes det gevind, der har den største tilhørende borehulsdiameter, oven i det først dannede gevind. Dette gælder fortrinsvis, når der er tale om forholdsvis små gevinddiamétre.When two threaded types are formed in the threaded hole, it may be advantageous to select threads whose corresponding borehole diameters are slightly different. First, a threaded hole is first produced in the normal manner with the thread having the smallest associated borehole diameter, and then the thread having the largest associated borehole diameter is formed on top of the first formed thread. This is preferably the case for relatively small thread diameters.

Ved større gevinddiametre kan det være fordelagtigt at starte med et borehul, der svarer til den af gevindtyperne, der har den største gevinddiameter. Det har vist sig, at forskellen mellem de to gevindtypers borehulsdiameter passende kan være af størrelsesordenen 0,5 mm.For larger thread diameters, it may be advantageous to start with a borehole corresponding to that of the thread types having the largest thread diameter. It has been found that the difference between the borehole diameters of the two thread types may suitably be of the order of 0.5 mm.

Selv om opfindelsens princip kan anvendes i forbindelse med møtrikker som sådanne, vil den som ovenfor forklaret være af særlig betydning, når der er tale om en møtrik, der indgår som en del af en genstand eller indretning, eller når en sådan genstand eller Indretning er forsynet med et gevindhul. Som eksempel på sådanne genstande, hvor opfindelsen er af særlig betydning, kan nævnes skrue-befæstigelsesindretninger af den type, der tjener til forankring af en skrue i mure, vægge eller plader, f.eks. som beskrevet i de danske patenter nr. 123950 og nr. 125145.While the principle of the invention may be applied in connection with nuts as such, as explained above, it will be of particular importance in the case of a nut forming part of an object or device, or when such object or device is provided with a threaded hole. Examples of such objects in which the invention is of particular importance are screw fasteners of the type which serve to anchor a screw in walls, walls or slabs, e.g. as disclosed in Danish Patents Nos. 123950 and Nos. 125145.

Opfindelsen angår også en fremgangsmåde til fremstilling af den ovenfor omtalte genstand, idet der i genstanden bores et hul, hvorefter der i dettes cylindriske væg udformes et til borehulsdiameteren svarende gevind, og fremgangsmåden ifølge opfindelsen er ejendommelig ved, at der derefter i den samme væg udformes en anden gevindtype, der svarer til en lidt større borehulsdiameter.The invention also relates to a method of making the above-mentioned article, drilling in the article a hole, then forming a thread corresponding to the borehole diameter, and the method according to the invention is characterized in that it is then formed in the same wall. another type of thread corresponding to a slightly larger borehole diameter.

Eksempel.Example.

I et møtrikemne af en aluminiumslegering blev dér boret et gennemgående hul med en diameter på 3,7 mm og en længde på ca. 10 mm. Derefter blev der ved hjælp af en snittap på normal måde i hullet skåret 3/16" Whitworth-gevind, dvs. med en gevinddiameter på 4,8 mm og med en gevindstigning på 1,1 mm. Derefter blev der ved hjælp af en anden snittap i det samme gevindhul skåret 5 mm metrisk gevind, der har en gevinddiameter på 5 mm og én gevindstigning på 0,8 mm.In a nut of an aluminum alloy there was drilled a through hole with a diameter of 3.7 mm and a length of approx. 10 mm. Then, by means of a cut pin, in the hole, 3/16 "Whitworth threads were cut in the normal manner, ie with a thread diameter of 4.8 mm and with a thread pitch of 1.1 mm. Then another cut in the same thread hole cut 5 mm metric thread, having a thread diameter of 5 mm and one thread pitch of 0.8 mm.

Claims (3)

4 U1181 Den således fremstillede møtrik samarbejdede uden vanskelighed såvel med en skrue, der var forsynet med 3/16" Whitworth-gevind, som med en skrue, der var forsynet med 5 mm metrisk gevind. Møtrikken blev monteret i en skruebefæstigelsesindretning af den type, der er beskrevet i dansk patent nr. 125145. Trækforsøg viste, at den skrueforbindelse, der opnåedes mellem skrue og møtrik, var stærkere end selve skruen. De bedste resultater opnås, hvis gevinddiameteren for de gevindtyper, der udformes i samme gevindhul, er nogenlunde lige store, og hvis gevindstigningen for de to gevindtyper ikke er alt for ensartede· Selv om der ovenfor først og fremmest er talt om gevindskæring ved hjælp af snittappe, kan man naturligvis også skære gevindene ved andre former for spåntagende bearbejdning. Det er endvidere muligt at udforme gevindene ved ikke-spåntagende bearbejdning, f.eks. ved rulning. Når gevindene skæres ved hjælp af snittappe, kan man fordelagtigt anvende snittappe, der hver især har forskellige, i forlængelse af hinanden beliggende aksiale afsnit, der tjener til Skæring af hver sin af de omhandlede gevindtyper. Det er klart, at man på tilsvarende måde som forklaret ovenfor i forbindelse med gevindhuller vil kunne udforme mindst to gevindtyper på samme skrue eller samme skruef omede legeme. Patentkrav.4 U1181 The nut thus produced cooperated without difficulty both with a screw provided with 3/16 "Whitworth threads as well as with a screw fitted with 5 mm metric threads. The nut was mounted in a screw fastening device of this type. Danish Patent No. 125145. Tensile tests showed that the screw connection obtained between the screw and nut was stronger than the screw itself.The best results are obtained if the thread diameter of the thread types formed in the same thread hole is approximately equal large, and if the thread pitch of the two thread types is not too uniform · Although the above is primarily talking about thread cutting by means of cut pins, you can of course also cut the threads by other forms of machining. the threads for non-cutting machining, for example by rolling. When the threads are cut by means of cutting pins, advantageously, cutting pins may be used, each having are different axially extending axial sections that serve to cut each of the types of threads in question. It is to be understood that in the same manner as explained above in connection with threaded holes, at least two thread types can be formed on the same screw or the same screw body. Claims. 1.
