Abstract

The axial and radial fixture for a roller bearing (10) in a bearing-cavity consists of the accessible outer ring (12) of the roller bearing (10) being fixed by means of stamped out pieces on its end-side. The fixture consists of a barrier (13) at least partly gripping round the outside of the roller-bearing outer ring (12). The barrier (13) consists of three sections displaced by roughly 120 deg. in relation to each other. The barrier is produced by dot riveting or by cold or hot forming from the bearing container material. USE - The method of axially and radially fixing a ballbearing in a bearing-seating is esp. by means of electrical tools.

Description

Die Erfindung betrifft ein Verfahren gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a method according to the preamble of claim 1.

Bei einem bei Elektrowerkzeugen bekannten Verfahren zur Beseiti­ gung des Axialspiels von Kugellagern und zum Toleranzausgleich wird Material des jeweiligen Kugellageraufnahmeteils spanlos so verformt, daß auf den Kugellageraußenring einwirkende Ausprägungen entstehen, die diesen in seiner Lage festlegen. Die Verformungs­ kräfte werden dabei wenigstens zum Teil von einem das Kugellager nach rückwärts abstützenden Sicherungsring aufgenommen.In a method known in power tools for removal axial play of ball bearings and for tolerance compensation becomes material of the respective ball bearing receiving part without cutting deformed that acting on the ball bearing outer ring arise that determine this in its position. The deformation Forces are at least partially from the ball bearing to the rear supporting circlip.

Ein derartiges Verfahren erfordert neben der Herstellung eines Einstichs für den Sicherungsring zwei Preßvorgänge, einmal bei der Montage des Kugellagers einschließlich des Sicherungsrings und einmal zum Herausnehmen des Spiels bei der Verprägung des Lageraufnahmematerials an mehreren Punkten.Such a method requires, in addition to the production of a Puncture for the circlip two presses, one at the assembly of the ball bearing including the locking ring and once to take out the game when embossing the Inventory material at several points.

Der Erfindung liegt die Aufgabe zugrunde, ein insbesondere für Elektrowerkzeuge geeignetes Verfahren zur axialen und radialen Fixierung eines Kugellagers im Lagersitz zu finden, das bei einer einwandfreien Festlegung des Kugellageraußenrings weniger Arbeits­ aufwand erforderlich macht.The invention is based, in particular for Power tool suitable method for axial and radial Finding a ball bearing in the bearing seat to find one proper fixing of the ball bearing outer ring less work effort required.

Diese Aufgabe ist erfindungsgemäß durch die Merkmale im kenn­ zeichnenden Teil des Anspruchs 1 gelöst.According to the invention, this object is characterized by the features in drawing part of claim 1 solved.

Zweckmäßige Ausgestaltungen der Erfindung sind in den Unter­ ansprüchen angegeben.Appropriate embodiments of the invention are in the sub claims specified.

Die Erfindung wird im nachstehenden anhand der Zeichnung, die als Ausführungsbeispiel ein in das Lagerschild eines Elektrowerkzeugs in Form eines Winkelschleifers oder einer Handkreissäge einge­ setztes, als Kugellager ausgebildetes Wälzlager veranschaulicht, erläutert.The invention is illustrated below with reference to the drawing, which as Embodiment in the end shield of a power tool in the form of an angle grinder or a hand-held circular saw set roller bearing designed as a ball bearing illustrates explained.

Es zeigen:Show it:

Fig. 1 einen Schnitt durch die Kugellageraufnahme im Lagerschild, Fig. 1 shows a section through the ball bearing receptacle in the bearing plate,

Fig. 2 das in die Lageraufnahme eingesetzte und gegen axiales und radiales Verschieben gesicherte Kugellager, Fig. 2, the backed inserted in the bearing receptacle and against axial and radial displacement of ball bearings,

Fig. 3 eine Ansicht des in der Lageraufnahme befindlichen Kugel­ lagers gemäß Fig. 2 in Richtung A. Fig. 3 is a view of the ball bearing in the bearing according to FIG. 2 in direction A.

Nach dem Einsetzen des Wälzlagers 10 (siehe Fig. 2) in Form eines Kugellagers in die gemäß Fig. 1 vorbereitete Lageraufnahme im Lagerschild 11 wird im Bereich der Stirnseite des zugängigen Kugellageraußenrings 12 befindliches Lageraufnahmematerial so verformt, daß eine Barriere 13 entsteht, die den Kugellageraußen­ ring 12 von außen her umgreift und damit das Kugellager 10 gegen axiales und radiales Verschieben sichert.After the rolling bearing 10 has been inserted (see FIG. 2) in the form of a ball bearing into the bearing receptacle in the bearing plate 11 prepared according to FIG. 1, the bearing receptacle material located in the region of the end face of the accessible ball bearing outer ring 12 is deformed such that a barrier 13 is formed which the ball bearing outer engages ring 12 from the outside and thus secures the ball bearing 10 against axial and radial displacement.

Die Barriere 13 erstreckt sich, wie insbesondere Fig. 3 er­ kennen läßt, über den gesamten Umfang des Kugellageraußenrings 12 hinweg und stützt diesen von außen lückenlos ab. Mitunter kann es sich auch als vorteilhaft erweisen, lediglich an eini­ gen Stellen entlang des Umfangs des Kugellageraußenrings 12 solche Barrierenabschnitte vorzusehen, beispielsweise an drei um ca. 120° gegeneinander versetzt angeordneten Bereichen.The barrier 13 extends, as can be seen in particular in FIG. 3, over the entire circumference of the ball bearing outer ring 12 and supports it from the outside without gaps. Sometimes it can also prove to be advantageous to provide such barrier sections only at a few locations along the circumference of the ball bearing outer ring 12 , for example in three regions offset by approximately 120 ° from one another.

Zur Herstellung der Barrieren 13 oder der Barrierenabschnitte eignen sich verschiedene Verfahren, beispielsweise das sogenannte Taumel- oder Punktnieten. Im ersten Fall erfolgt die Ver­ formung des Lageraufnahmematerials auf einer Berührungslinie von der Länge des Nietkopfradius, im zweiten Fall durch eine Punkt­ berührung zwischen Nietdöpper und Niet. Der Niet ist in beiden Fällen die an den zugängigen Kugellageraußenring 12 tangierende Materialzone 14 der Kugellageraufnahme, also praktisch ein Ring­ bauteil. Die Anwendung des bekannten Punkt-Nietverfahrens weist gegenüber dem Taumel-Nieten den Vorteil auf, daß sich eine Ver­ härtung des Materials fast ohne Strukturveränderung ergibt.Various methods are suitable for producing the barriers 13 or the barrier sections, for example the so-called wobble or point riveting. In the first case the bearing material is deformed on a line of contact the length of the rivet head radius, in the second case by a point contact between the riveting tool and the rivet. In both cases, the rivet is the material zone 14 of the ball bearing receptacle tangent to the accessible ball bearing outer ring 12 , that is to say practically a ring component. The use of the known point riveting method has the advantage over the wobble riveting that there is a hardening of the material with almost no structural change.

Die Barriere bzw. die Barrieren 13 können dabei durch Kaltver­ formen oder durch Warmverformen des Lageraufnahmematerials herge­ stellt werden. Die jeweilige Verformungsmethode hängt dabei auch von der Beschaffenheit des jeweils zu verformenden Materials ab.The barrier or the barriers 13 can be formed by Kaltver or by thermoforming the bearing material. The respective deformation method also depends on the nature of the material to be deformed.
