Description
In vielen Anwendungsfällen von Wälzlagern, z.B. auch bei
der Tatzrollenlagerung eines Bahnmotors, sind die Innenringe
der Wälzlager für das Abziehen des Lagers von der
Welle nicht zugänglich» Die Lager nüssen in solchen Fällen über den Außenring abgezogen werden, wobei die Kräfte über
die Wälzkörper auf den auf die Welle aufgepreßten Innenring übertragen werden. Bei einem Abziehen über den. Außenring und
die Wälzkörper treten häufig Beschädigungen des Wälzlagers auf, so daß dieses in den meisten Fällen nicht wieder verwendet
v/erden kann.In many applications of rolling bearings, e.g. also with
the roller bearings of a railway engine, the inner rings of the roller bearings are used to pull the bearing off the
Shaft not accessible »In such cases, the bearings must be withdrawn via the outer ring, with the forces being transmitted via the rolling elements to the inner ring pressed onto the shaft. When pulling over the. The outer ring and the rolling elements are often damaged, so that in most cases it cannot be reused.
Es ist daher aus der DT-OS 1 400 31 β bekannt, den auf eine
Welle aufgepreßten Innenring eines Wälzlagers in axialer
Richtung breiter als den Außenring auszubilden und ihn mit Mitteln zum unmittelbaren Ansetzen einer Abziehvorrichtung
zu versehen» Bei dem bekannten Wälzlager ist der Innenring im Bereich seiner Verlängerung mit einer Nut oder einer
sonstigen Querschnittsveränderung versehen, die eine zum Absetzen der Abziehvorrichtung dienende Kante bildet.It is therefore known from DT-OS 1 400 31 β, the pressed onto a shaft inner ring of a roller bearing in the axial
In the direction wider than the outer ring and to provide it with means for the direct attachment of a pulling device
other cross-sectional change provided, which forms an edge serving to set down the puller.
Durch die vorliegende Neuerung soll die mittels der Abziehvorrichtung
auf den Innenring des Wälzlagers aufgebrachte
Kraft möglichst einfach und gleichmäßig übertragen v/erden. Gemäß der Neuerung ist der Innenring an der über den Außenring
hinausragenden Fläche mit einem Gewinde versehen, auf das als Abziehvorrichtung ein Gewindering aufschraubbar ist.
Die Kraftübertragung auf den Innenring erfolgt also in gleichmäßiger Weise über das Gewinde. Sie kann an dem als Abziehvorrichtung
dienenden Gewindering auf mechanische oder hydraulische W>jise aufgebracht werden.The present innovation is intended to be applied to the inner ring of the roller bearing by means of the puller
Transfer force as simply and evenly as possible. According to the innovation, the inner ring is provided with a thread on the surface protruding beyond the outer ring, onto which a threaded ring can be screwed as a pulling device. The power transmission to the inner ring takes place evenly via the thread. It can be applied to the threaded ring, which serves as a pulling device, on mechanical or hydraulic jacks.

Ira folgenden sei die Neuerung anhand dey in den Figuren 1 und 2 dargestellten AusfUhrimgnbei spiels noch nilher erläutert. Fig. 1 zeigi; einen Längsschnitt durch ein gemäß der Neuerung aucneuilucicu Valzlu^i-r, Fij.·,. Z ^eigt ebüniällG ins Längsschnitt ein gemäß der Neue rung ausgebildetes Wälzlager mit aufgebrachter Abziehvorrichtung.In the following, the innovation will be explained in more detail with reference to the execution example shown in FIGS. 1 and 2. Fig. 1 shows; a longitudinal section through a according to the innovation aucneuilucicu Valzlu ^ ir, Fij. · ,. Z ^ isplays ebüniällG the longitudinal section, a trained according to the new tion bearings with applied puller.
Bei dem in Fig. 1 ciirgestellten Ausführungsbeispiel enthält das Wälzlager 1 als 'wälzkörper ?. Kcgtslrollen. Diese liegen zwischen de.;· Außenring 3 und de;:» Innanr.ing 4. In axialer Richtung ist der Inr.enring 4 breiter als der Außenring 3 und i.'/b an der über dor; Außenring 3 hinausragenden Fläche 5 mit einem Guv.lnde G versehen. Dieses Gev/inde 6 bildet die Möglichkeit zil:i unmittelbaren Ansetzen einer Abhiehvorrichtung. In the embodiment shown in FIG. 1, the roller bearing contains 1 as "rolling elements ". Kcgtslrolle. These lie between de.; · Outer ring 3 and de ;: »Inner ring 4. In the axial direction, inner ring 4 is wider than outer ring 3 and i. '/ B on the over dor; Outer ring 3 protruding surface 5 is provided with a guv.land G. This thread 6 forms the possibility of: i immediate attachment of a lifting device.
Fig. 2 zeigt ein ebenfalls gciiLlß der Neuerung ausgebildetes Wälzlager 1, bei den auf den Innonring 4 als Abziehvorrichtung 7 ein Gev.-.\rj:lcring 0 aufgeschraubt ist. Das Innengewinde 9 des Gewinderinges 8 entspricht dem Gewinde 6 am Innevvln£ h des V/<".l:ila(jcrs 1.

Hit Hilfe der Abdrückschrauben ^1 und den Gewindering 8 kann so in einfacher Weise durch mechanische Kräfte der Innenring 4 von seinem Sitz 14 auf der Welle 13 entfernt v/erden. Die V'älzkörper 2 brauchen dabei keinerlei Kräfte zu übertragen, da die Abziehvorrichtung 7 unmittelbar an dem Innenring 4 des Wälzlagers 1 angreift.2 shows a roller bearing 1 which is also designed according to the innovation and in which a Gev .-. \ Rj: lcring 0 is screwed onto the Innonring 4 as a pulling device 7.
