Description

BeschreibungDescription

Die Erfindung betrifft eine Klemmspaltmutter (1) mit einer zwangsfreien Klemm- und Löse-Verschraubung (2,3,4,5,6,7,11,12,13).The invention relates to a clamping gap nut (1) with a non-constrained clamping and loosening screw connection (2,3,4,5,6,7,11,12,13).

Klemmspaltmuttern sind in der Technik hinlänglich bekannt.Sie sollen die Mutter über Klemmung auf dem Gewinde sichern.Dazu werden Muttern geschlitzt und die beiden Spaltenden mittels Spannschrauben miteinander verbunden..Clamping gap nuts are well known in technology. They are intended to secure the nut by clamping it onto the thread. To do this, nuts are slotted and the two gap ends are connected to one another using clamping screws.

Der Erfindung liegt nun das Problem zugrunde,daß bei sehr großen Muttern auch sehr große Klemmspaltreduzierungen (Beispiel: d=600mm ==>Klemmspaltreduzierung=2,5mm) erforderlich sind.Dies führt zur Aufklaffung der Spaltstirnflächen (18 ) zueinander in einer nicht mehr tolerierbaren Größenordnung (I.o.g. Beispiel: 0,5°).Dies hat wiederrum direkten Einfluß auf die Schrauben-Gewinde-Verbindung,da der Schraubenkopf ohne eine Ausgleichsmög- lichkeit schräg verspannt werden würde. Die Erfindung löst dieses Problem durch das Unterlegen von Kugelpfannen (4,5 ) unter die Schraubenköpfe ( 9,10) sowie durch die Ausführung des Schaftdurchgangsloches(11,12) als Langloch (13).The invention is based on the problem that very large clamping gap reductions are required for very large nuts (example: d=600mm ==> clamping gap reduction=2.5mm). This leads to the gap between the gap faces (18) becoming wider than can be tolerated (example above: 0.5°). This in turn has a direct effect on the screw-thread connection, since the screw head would be clamped at an angle without a compensation option. The invention solves this problem by placing ball sockets (4,5) under the screw heads (9,10) and by designing the shaft through hole (11,12) as an elongated hole (13).

Ein weiteres Problem,welches der Erfindung zugrunde liegt,ist der bei üblichen Klemmspaltmuttern fehlende,integrierte Lösemechanismus. Dieses Problem wurde durch ein Schraubenkopfhalteblech ( 6) gelöst,welches die Spannschraube (2,3 ) beim Losdrehen in ihrer Position hält,wodurch der Klemmspalt (19 ) vergrößert wird.Gemäß der Anzahl der Spannschrauben (2,3 ) wird das Schraubenkopfhalteblech (6 ) dabei mit Montagelöchern (14) versehen,durch die das Anziehen/Lösen der Spannschrauben (2,3 ) ermöglicht wird. Das Schraubenkopfhalteblech (6) ist dabei mittels einer Verbindungsschraube (7) mit der Klemmspaltmutter (1) verschraubt. Damit wird es möglich.solche Muttern auch bei starker Korrosion in den Gewindegängen zu lösen.Another problem underlying the invention is the lack of an integrated release mechanism in conventional clamping gap nuts. This problem was solved by a screw head retaining plate (6) which holds the clamping screw (2, 3) in its position when it is loosened, thereby increasing the clamping gap (19). Depending on the number of clamping screws (2, 3), the screw head retaining plate (6) is provided with mounting holes (14) through which the clamping screws (2, 3) can be tightened/loosened. The screw head retaining plate (6) is screwed to the clamping gap nut (1) using a connecting screw (7). This makes it possible to loosen such nuts even when there is severe corrosion in the threads.

Ein weiteres Problem,welches der Erfindung zugrunde liegt.ist die Verhinderung eines axialen Versatzes der beiden Spaltstirnflächen (18 ) zueinander,welcher von Materialspannungen herrührt,die bei der Herstellung des Klemmspaltes (19) frei werden. Dieses Problem wurde mittels Spannschrauben (2,3 ) mit gehärtetem und eng toleriertem Schaftbereich (15 ) sowie mittels eines in der Breite ebenfalls eng toleriertem Schaftdurchgangslangloches (11,12,13) gelöst.A further problem on which the invention is based is the prevention of an axial offset of the two gap end faces (18) to one another, which arises from material stresses that are released when the clamping gap (19) is produced. This problem was solved by means of clamping screws (2, 3) with a hardened and closely tolerated shaft area (15) and by means of a shaft through-hole (11, 12, 13) that also has a closely tolerated width.

Ein weiteres Problem,welches der Erfindung zugrunde liegt,ist die Reduzierung der Reibung zwischen Klemmspaltmuttern-Stirnseite(16 ) und der Stirnseite des zu sichernden Bauelementes (z.Bsp. Wälzlager,Kupplungsscheibe).A further problem underlying the invention is the reduction of friction between the clamping gap nut face (16) and the face of the component to be secured (e.g. rolling bearing, clutch disc).

Diese Reibung führt beim Anziehen der Mutter zu unnötig hohen Anzugsmomenten. Dieses Problem wurde mittels eines stirnseitigen Gleitbelages (z.Bsp. PTFE) (17 ) gelöst.This friction leads to unnecessarily high tightening torques when tightening the nut. This problem was solved by using a sliding coating on the front side (e.g. PTFE) (17).
