Abstract

The precision friction coefficient measuring instrument (1) possesses, on its load arm (2), an engaging element (3) for adjusting the tapered-roller inner ring with respect to the tapered-roller outer ring and, on its force arm (4), a crank (5) for initiating a dragging rotation. The crank (5) consists of a connecting rod (10) and a handle (9) rotatably held thereon. A rotatable scale (6) with a pointer (7) and a drag pointer (8) is situated approximately in the centre of the friction coefficient measuring instrument. <IMAGE>

Description

Die Erfindung bezieht sich auf einen Drehmomentenschlüssel mit Skalenmeßuhr und Schleppzeiger. Drehmomentenschlüssel, insbesondere auch mit Schleppzeiger sind hinreichend bekannt, siehe hierzu z.B. DE-PS 709 212. 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.The invention relates to a torque wrench with dial gauge and drag pointer. Torque wrenches, especially those with a pointer, are well known, see e.g. DE-PS 709 212. 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 measuring torque" in "Fine equipment technology", 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 Lagereibmomentes erzielt. Mit der DE-AS 15 25 256 ist der Hinweis auf ein derartiges Verfahren zur Ermittlung des einer gewünschten Vorspannkraft entsprechenden Reibmomentes einer Wälzlageranordnung gegeben. Das Verfahren ist unabhängig davon anwendbar, ob Lagerluft oder Vorspannung als endgültige Einstellung gewünscht wird. Der Wert für das Lagerreibmoment ist ein Maß für die Vorspannung.In motor vehicle construction, preloaded bearings are provided in the motor vehicle pinion and differential or similar places. A precise, constant and effective method of bearing adjustment is achieved by using the bearing friction torque. DE-AS 15 25 256 provides an indication of such a method for determining the frictional torque of a rolling bearing arrangement corresponding to a desired preload force. The method can be used regardless of whether internal clearance or preload is required 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 to provide an inexpensive, accurate and easy-to-use device for adjusting tapered roller bearings.

Diese Aufgabe wird durch die im Anspruch 1 angegebene Verwendung eines Drehmomentschlüssels gelöst.This object is achieved by the use of a torque wrench specified in claim 1.

Die beanspruchte Verwendung eines Drehmomentenschlüssels als Reibwertmesser gestattet nun eine wesentliche Vergrößerung des Meßbereiches, eine große Genauigkeit wie auch eine bessere Ablesbarkeit durch den Schleppzeiger. Hervorzuheben ist, daß auf ein handelsübliches Instrument zurückgegriffen werden kann, dem nunmehr ein doppeltes Einsatzgebiet zugeordnet werden kann (2. Indikation), wodurch neben den vorbeschriebenen technischen Vorteilen auch Kosten reduziert werden und Werkzeughaltung reduziert wird.The claimed use of a torque wrench as a coefficient of friction now permits a substantial enlargement of the measuring range, great accuracy as well as 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 area of application (2nd indication), which, in addition to the technical advantages described above, also reduces costs and tool holding.

Am Kraftarm ist eine Kurbel angeordnet. Dies veranlaßt den Monteur zu der erforderlichen schleppenden Drehbewegung, so daß ein unkontrolliertes Losreißmoment vermieden wird.A crank is arranged on the power arm. This causes the fitter to carry out the required sluggish rotary movement, so that an uncontrolled tearing torque is avoided.

Die Kurbel weist eine Griff auf, der gegenüber der kraftarmfesten Kurbelstange drehbar ist. Solcherart wird ein verbessertes Feingefühl für die erforderliche schleppende Drehbewegung erzielt.The crank has a handle that is rotatable relative to the crank arm that is fixed to the power arm. In this way, an improved sensitivity to the required slow rotational movement is achieved.

Die Erfindung ist in einem Ausführungsbeispiel dargestellt.The invention is shown in one embodiment.

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 Kraftarm 4 ein Kurbel 5 zur Einleitung einer schleppenden Drehbewegung. Die fest mit dem Ende des Kraftarmes 4 verbundene Kurbel 5 besteht aus einer Kurbelstange 10 und einem an ihr drehbar angeordneten Griff 9, z.B. einem Kugelkopf. Ungefähr in der Mitte des Reibwertmessers befindet sich eine drehbare Skala 6 mit einem Zeiger 7 und einem Schleppzeiger 8.The precision coefficient of friction meter 1 has on its load arm 2 an engagement element 3 for the adjustment of the tapered roller inner ring to the tapered roller outer ring and on its power arm 4 a crank 5 for initiating a slow rotational movement. The crank 5, which is firmly connected to the end of the power arm 4, consists of a crank rod 10 and a handle 9, for example a ball head, which is rotatably arranged on it. Approximately in the middle of the coefficient of friction is a rotatable scale 6 with a pointer 7 and a drag pointer 8.

Claims (1)

  1. Use of a torque spanner (1) with a direct-reading dial gauge (6) and a settable pointer (8) as precision friction-value gauge for adjusting tapered roller bearings in axles and gearings, the engaging end (2) of the torque spanner (1) having an engaging member (3) for adjusting the inner ring of the tapered roller relative to the outer ring of the tapered roller, and the handle end (4) of the torque spanner (1) having a grip-type crank (5) which extends parallel to the axis of the engaging member (3).
