Description

  

  Elektromotor mit in Kugellagern     laufender    Welle    Für den Antrieb von Haushaltmaschinen,  z. B. Kühlmaschinen, werden geräuschlos lau  1'ende Elektromotoren verlangt. Aus diesem  (runde baute man solche Motoren mit     Gleit-          Lig-ern,    denn. die Kugellager machen zuviel       ('eräuseh,        Irin    dieselben     iin    Haushalt     ver-          wilirclen    zu können.  



       Aus        Betriebssicherheitsgründen    ist aber der       Kugellagermotor    dem     Gleitlagermotor    vorzu  ziehen. Die vorliegende     Erfindung    bezweckt,  Mittel zu schaffen, um die Übertragung des       Kugellagergeräusches    auf die Umgebung zu  verhindern.  



       (gemäss    der Erfindung ist zwischen den  Kugellagern und dem Lagerschild eine Schicht  ans schalldämpfendem Material angeordnet.  



  Diese     Sehieht    kann aus Gummi, v     or7ugs-          weise        synthetischem        Crummi,    bestehen. Die       Sehieht    kann auch in der Umfangsrichtung       verlaufende        L?nterbreehungen    aufweisen, da  mit die     Cleräusch-L?bertragung    von Kugellager  auf Lagerschild noch geringer wird.  



  Für die Montage der Kugellager ist es  zweckmässig, die Schicht nicht unmittelbar auf       dein    Kugellager anzuordnen, sondern zwischen  dieser Schicht und dem Kugellager noch einen  Metallring einzusetzen oder die Schicht     zwi-          sehen    einem, innern und einem     äussern    Metall  ring zu halten.  



  In der beiliegenden     Zeichnung    sind zwei       beispielsweise    Ausführungsformen des Erfin  dungsgegenstandes je in einem Ausschnitt dar  gestellt.    Nach     Fig.    1 ist zwischen dem Lagerschild  1 und dem auf der Welle des Elektromotors  sitzenden Kugellager 2 ein Ring 3 aus schall  dämpfendem Material, z. B. aus Gummi, ins  besondere     synthetischem    Gummi, angeordnet.  



  Wie dies     Fig.    2 zeigt, ist der Ring 3 zwi  schen einem äussern Metallring 4 und einem  innern Metallring 5 gehalten.



  Electric motor with shaft running in ball bearings For driving household machines, e.g. B. cooling machines, noiseless, lukewarm electric motors are required. From this (round one built such motors with sliding ligers, because. The ball bearings make too much ('excuse that Irish can use them in the household.



       For operational safety reasons, however, the ball bearing motor is preferred to the plain bearing motor. The present invention aims to provide a means to prevent the transmission of ball bearing noise to the environment.



       (According to the invention, a layer of sound-absorbing material is arranged between the ball bearings and the end shield.



  This eye can be made of rubber, preferably synthetic crummi. The sight can also have longitudinal extensions running in the circumferential direction, since the transmission of noise from the ball bearing to the bearing plate becomes even less.



  For the assembly of the ball bearings it is advisable not to arrange the layer directly on your ball bearing, but to insert a metal ring between this layer and the ball bearing or to hold the layer between an inner and an outer metal ring.



  In the accompanying drawings, two exemplary embodiments of the subject of the invention are each provided in a section is. According to Fig. 1, a ring 3 made of sound-absorbing material, for example, is between the end shield 1 and the ball bearing 2 seated on the shaft of the electric motor. B. made of rubber, in particular synthetic rubber, arranged.



  As shown in FIG. 2, the ring 3 is held between an outer metal ring 4 and an inner metal ring 5.
