Abstract

A device measuring the radial force acting on a bearing uses a double ring mounted on the bearing, with a strain gauge carrying arms connecting the two parts. The design increases accuracy by using more strain gauges. A bridge type measurement circuit can be applied. An inner (2) and outer (1) ring are connected by two small radial arms (3, 3a) which carry an array of two strain gauges (7, 7a) each. The whole unit is mounted on the bearing concerned (5) and the strain gauges connected in a bridge formation to external circuitry to provide the force measurement required.

Description

lzlagergehäuse bearing housing

(Zusatz zu P 27 16 024.3) Die Erfindung betrifft ein Wä@zlagergehäuse, eingerichtet zum @essen der auf des Wälzlagereinwirkenden Padialkraft mittels elastisch verformbarer @@ieder und eines el@@trischen si @al-@ebers, wobei nach Patent (Patentan@eldung @ 27 10 024.3) @as elastisch verformbare @lied ein senkrecht zur Kraftrichtung verlaufender kurzer Hadialsteg ist, welcher den @ußeren, Befestigungszwecken dienenden flansch mit den inneren, das Wälzlayer tragenden Nalter fest verbindet und an den beider. der Biegebeanspruchung unterworfenen Seiten des Radialsteges mit @ehnungsmesstreifen besetzt ist. (Addition to P 27 16 024.3) The invention relates to a roller bearing housing, set up to measure the padial force acting on the roller bearing by means of elastic deformable @@ ieder and an el @@ tric si @ al- @ boar, whereby according to patent (patent application @ 27 10 024.3) @as an elastically deformable @long that runs perpendicular to the direction of force Short Hadialsteg is, which the @ outer, fastening purposes serving flange with the inner nalter that supports the Wälzlayer and with the two. Sides of the radial web that are subject to bending stress with strain gauges is busy.

@ach dem Hauptpatent sind zwei konzentrische Ringe miteinander über einen einzigen Padialsteg verbunden, wobei der Außenring als Anbauflansch mit Befestigungs@chrungen ausgebildet ist, Während der Innenring als Halter des Wälzlagers unter Einwirkung der zu messenden Kraft eine Schwenkbewegung ausfUhrt und auf diese Weise einen elektrischen Signalgeber bee4nfluAt.According to the main patent, two concentric rings are over each other connected by a single padial bar, with the outer ring as a mounting flange with fastening stanchions is designed, while the inner ring acts as a holder of the rolling bearing the force to be measured executes a pivoting movement and in this way an electrical one Signal transmitter influAt.

Das solchermassen aufgebaute Wälzlagergehäuse @ibt zu keinerlei Beanstandung Anlaß, sofern zwischen Welle und Wälzlager eine @leit bis Schiebesitzpassung besteht, dank welcher das Gehäuse sich jederzeit leicht von der Welle abziehen läßt.The roller bearing housing constructed in this way does not give rise to any complaints Occasion, provided that there is a sliding fit between the shaft and the roller bearing, thanks to which the housing can be easily removed from the shaft at any time.

Bei festeren Sitzen (Haftsitz, Treibsitz) ist das Abziehen da- @egen erschwert mit Rücksicht darauf, daß ja am Außenring bzw.In the case of a more firm fit (tight fit, driving seat), pulling off is @egen made difficult with regard to the fact that yes on the outer ring or

flansch gezogen wird, während der das Wälzlager tragende und ar: Steg federnd gehaltene Innenring bzw. Halter schon durch die reringste Achsialschwenkung ein Klemmen zu erzeugen verma@.flange is pulled, while the bearing supporting and ar: web Resiliently held inner ring or holder already through the smallest axial pivoting to generate a clamping verma @.

Zur Behebung dieses fibelstandes sind zus'itzliche Konstruktionselemente denkbar, wie konische Stifte oder Keile, die vor den Abziehvorgang zwecks Blockierung des Tnnenringes in die Vorrichtung einzusetzen wären. Derartige Lösungen wurden aber den Aufbau verteuern und die Handhabung konplizieren.Additional construction elements are needed to remedy this issue conceivable, such as conical pins or wedges, which are used before the removal process for the purpose of blocking of the inner ring would have to be inserted into the device. Such solutions were made but make the structure more expensive and imply handling.

Per Erfindung liegt somit die Aufgabe zugrunde, ein Wälzlagergehäise der eomgamgs gemammtem @attung auf möglichst einfache Weise so zu gestalten, dan ohne wesentliche Beeinflussung der @essfunktion ein Blockieren des Halters auf der Welle bein Abziehen des Lagers bzw. Larergehäuses verhindert wird.The object of the invention is thus to provide a roller bearing housing the eomgamgs gemammtem @attung in the simplest possible way, then Blocking of the holder on the without significantly influencing the measuring function Shaft when pulling off the bearing or Larer housing is prevented.

Die Lösung dieser Aufgabe ist erfindungsgemäß gebildet durch einen zweiten, den Flansch mit den Halter verbindenden Padialsteg, er dem ersten Badialsteg diametral gegenüberliegend angeordnet ist.The solution to this problem is formed according to the invention by a second padial bar connecting the flange to the holder, he the first badial bar is arranged diametrically opposite.

rer Innenring ist dann auf entgegengesetzten Seiten an Außenring abgestützt, wird also bein Abziehen des Lagers ausschlielich in Pichtung der Lagerachse beansprucht, ohne daß eine Kipptendenz entsteht, die sonst zu einem Verklemmen auf der llelie ftlhren kann.rer inner ring is then supported on opposite sides of the outer ring, so when the bearing is withdrawn it is only stressed in the direction of the bearing axis, without causing a tendency to tilt, which would otherwise lead to jamming on the llelie can lead.

Zusätzliche Kosten sind mit dieser Ausbildung praktisch nicht @@@-bunden, da es nur un eine andere Bearbeitung einer einzigen, Innen-und Außenring bildenden Scheibe geht.Additional costs are practically not bound with this training, as there is only one other machining process, forming a single inner and outer ring Disc goes.

An beiden Radialstegen können grundsätzlich Dehnungsnesstreifen angebracht sein, die sich zu einer elektrischen Messbrücke zusanmenschalten lassen.In principle, stretch strips can be attached to both radial webs that can be interconnected to form an electrical measuring bridge.

ferner kann es vortellbaft sein, beide Radialstege unterschiedlich stark auszubilden, wobei wenigstens der schwächere Radialsteg mit Dehnungsmesstreifen versehen ist.Furthermore, it can be advantageous for both radial webs to be different form strong, with at least the weaker radial web with strain gauges is provided.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung im ruerschnitt dargestellt.An embodiment of the invention is shown in the drawing in ruschnitt shown.

Diese Zeichnung entspricht weitgehend der des '-lteren Vorschla@s.This drawing largely corresponds to that of the earlier proposal.

jan erkennt wieder: Außenring bzw. Flansch 1, Innenring bzw i:itrr 2 und Padialsteg 3 mit den Dehnungsmesstreifen 7, sowie die efestigungsbohrungen 4, das Wälzlager 5 und die Anschlagbolzen .jan recognizes: outer ring or flange 1, inner ring or i: itrr 2 and Padialsteg 3 with the strain gauges 7, as well as the fixing holes 4, the roller bearing 5 and the stop bolts.

Neu hlnzugekonmen ist ein zweiter Radislsteg 3a, diametral entgegengesetzt dem Steg 3. Die beiden Stege liegen in der gleichen durch die Bezugslinien angedeuteten Ebene 3 - 3a.A second radial web 3a, diametrically opposite, has been added the web 3. The two webs are in the same position indicated by the reference lines Level 3 - 3a.

Der zweite Badialsteg braucht zwar nicht it Dehnungsmesstreigen 7a ausgertistet zu werden, wäre aber dafür gut geeignet. Hiervon läßt sich Gebrauch machen, um beispielsweise je zwei Nesstreifen 7 und 7a zur Vollbrücke zusammenzuschalten. Danit könnten diese vier Messtreifen alle in der mittleren fuerschnittsebene liegen, was gewisse Applikations-Vorteile mit sich bringt.The second badial bridge does not need strain gauges 7a However, to be cleared out would be well suited for this. This can be used make, for example, to interconnect two Nes strips 7 and 7a to form a full bridge. Then these four measuring strips could all be in the middle cross-sectional plane, which has certain application advantages.

Wenn man bein älteren Vorschlag von einem "Biegesvsten mit @reiträger" sprechen könnte, so handelt es sich Jetzt um eie "ein@@-spannten Träger", der bei gleicher Breite wesentlich schwä@@@ sein muß, um in beiden fällen über dieselbe Federkonstante @@@@ zu verfügen (f = Durchfederung des Innenringes 2). Die Zeich@ung zeirt die beiden Radlalstege 3 und 3a in gleicher Starke, doch ist es durchaus sinnvoll, sie ungleich stark zu machen und die Dehnungsmesstreifen nur an dem schwächeren Steg (z.P. 3a) anzubringen, um die Messempfindlichkeit des Systems zu erhöhen Form und Verlauf der Radialstege brauchen nicht zwingend der Zeichnung zu entsprechen. Die dargestellte Form ergibt sich aus der als vorteilhaft, billig und platzsparend angesehenen llerstellungsart, närlich den beiden Pohrungen, deren Abstand @@ Stärke des Steges eindeutig bestlrmt. @ünstig, weil durch die Dehnunpsnesstreifen als Kerbspannung korrekt erfaßtbar, ist auch die Lastkonzentration im dünnsten und @ut zugänglichen @uerschni@t.If you have an older suggestion from a "Biegesvsten mit @ reiträger" could speak, so it is now about a "a @@ - tensioned carrier", who at of the same width must be substantially schwä @@@ in order to be about the same in both cases Spring constant @@@@ (f = deflection of the inner ring 2). The drawing produces the two Radlalstege 3 and 3a in the same strength, but it makes perfect sense, to make them unevenly strong and the strain gauges only on the weaker one To attach a bar (e.g. 3a) in order to increase the measuring sensitivity of the system and the course of the radial webs do not necessarily have to correspond to the drawing. The shape shown results from being advantageous, cheap and space-saving respected type of creation, namely the two pohrings, their distance @@ strength of the jetty clearly exposed to radiation. @ Inexpensive, because the stretch marks as notch stress correctly recorded, the load concentration in the thinnest and most accessible @ uerschni @ t.

Andere Formgebungen der Radialstege liegen Jedoch durchaus im Rahmen der Erfindung.However, other shapes of the radial webs are certainly within the scope the invention.
