Abstract
Description
Die Erfindung bezieht sich auf einen Drehmomentenschlüssel mit Skalenmeßuhr und Schleppzeiger.The invention relates to a torque wrench with dial gauge and drag pointer.
Drehmomentenschlüssel, insbesondere auch mit Schleppzeiger sind hinreichend be
kannt, siehe hierzu z. B. DE-PS 7 09 212. Es sind auch Meßuhren bzw. -Vorrichtungen mit Schleppzeigern zur Messung von Drehmomenten für verschiedene Einsatzzwecke bekannt, siehe hierzu Prospekt der Firma
Stenzel: "Waters Drehmoment-Meßuhren", 1975; Skornjakow:
"Geräte zur Messung von Drehmomenten" in "Feingerätetechnik",
5. Jahrgang, 1956, Heft 4, Seite 174 bis 175.Torque wrenches, in particular also with trailing pointers, are sufficiently known, see, for example, B. DE-PS 7 09 212. There are also dial gauges or devices with drag pointers for measuring torque for various purposes, see the prospectus of the Stenzel company: "Waters Torque Dial Gauges", 1975; Skornjakow:
"Devices for the measurement of torques" in "Feingerätetechnik", 5th year, 1956, issue 4, pages 174 to 175.
Im Kraftfahrzeugbau werden beim Kraftfahrzeug-Ritzel und
-Differential oder ähnlichen Stellen vorgespannte Lager
vorgesehen. Eine genaue, konstante und wirksame Methode der
Lagereinstellung wird durch die Benutzung des Lagerreibmo
mentes erzielt. Mit der DE-AS 15 25 256 ist der Hinweis auf ein derartiges Verfahren
zur Ermittlung des einer gewünschten Vorspannkraft entspre
chenden Reibmomentes einer Wälzlageranordnung gegeben. Das Verfahren ist unabhängig davon anwend
bar, ob Lagerluft oder Vorspannung als endgültige Einstel
lung gewünscht wird. Der Wert für das Lagerreibmoment ist
ein Maß für die Vorspannung.
In motor vehicle construction, preloaded bearings are provided for the motor vehicle pinion and differential or similar locations. A precise, constant and effective method of bearing adjustment is achieved through the use of bearing friction torque. With DE-AS 15 25 256, reference is made to such a method for determining the friction torque of a rolling bearing arrangement corresponding to a desired preload force. The method can be used regardless of whether you want clearance or preload as the final setting. The value for the bearing friction torque is a measure of the preload.
Aufgabe der Erfindung ist es daher, eine preisgünstige genaue und einfach handhabbare Vorrichtung zur Einstellung von Kegelrollenlagern anzugeben.The object of the invention is therefore an inexpensive precise and easy to use device for setting of tapered roller bearings.
Diese Aufgabe wird durch die im Anspruch 1 angegebene Verwendung eines Drehmomentschlüssels gelöst.This object is achieved by the use specified in claim 1 a torque wrench solved.
Die Verwendung des bekannten Drehmomentenschlüssels als
Reibwertmesser gestattet nun eine wesentliche Vergrößerung
des Meßbereiches, eine große Genauigkeit wie auch eine bes
sere Ablesbarkeit durch den Schleppzeiger. Hervorzuheben
ist, daß auf ein handelsübliches Instrument zurückgegriffen
werden kann, dem nunmehr ein doppeltes Einsatzgebiet zuge
ordnet werden kann (2. Indikation), wodurch neben den vor
beschriebenen technischen Vorteilen auch Kosten reduziert
werden und Werkzeughaltung reduziert wird.
The use of the known torque wrench as a coefficient of friction now allows a substantial increase in the measuring range, great accuracy as well as a better readability by the drag pointer. It should be emphasized that a commercially available instrument can be used, which can now be assigned to a double application area (2nd indication), which in addition to the technical advantages described above also reduces costs and tooling is reduced.
In einer vorteilhaften Ausgestaltung der Erfindung wird am Kraftarm eine Kurbel angeordnet. Dies veranlaßt den Monteur zu der erforderlichen schleppenden Drehbewegung, so daß ein unkontrolliertes Losreißmoment vermieden wird.In an advantageous embodiment of the invention on Powerless a crank arranged. This causes the fitter to the required dragging rotary motion so that a uncontrolled breakaway torque is avoided.
Die Erfindung ist in einem Ausführungsbeispiel dargestellt. Es zeigtThe invention is shown in one embodiment. It shows
Fig. 1 einen Präzisions-Reibwertmesser in der Draufsicht, Fig. 1 a precision Friction gauge in plan view,
Fig. 2 einen Präzisions-Reibwertmesser in der Seitenansicht. Fig. 2 shows a precision friction meter in side view.
Der Präzisions-Reibwertmesser 1 weist an seinem Lastarm 2 ein Eingriffselement 3 für die Anstellung von Kegelrollen- Innenring zu Kegelrollen-Außenring auf und an seinem Kraft arm 4 eine Kurbel 5 zur Einleitung einer schleppenden Drehbewegung. Ungefähr in der Mitte des Reibwertmessers be findet sich eine drehbare Skala 6 mit einem Zeiger 7 und ei nem Schleppzeiger 8.The precision friction meter 1 has on its load arm 2 an engaging element 3 for the employment of tapered roller inner ring to tapered roller outer ring and on its arm 4 a crank 5 for initiating a slow rotational movement. Approximately in the middle of the coefficient of friction meter there is a rotatable scale 6 with a pointer 7 and egg pointer 8 .
