KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Das neue Kugellager soll hauptsächlich für Kraftwagen, Dynamos, Maschinen u. dgl. an-' gewendet werden. Ein vollkommenes Kugellager besteht aus zwei an den Kugellaufflächen gerillten Laufringen, welche keinerlei schwächende, die gleichmäßige Härtung störende Durchbrechung oder Aussparung haben und welche durch " Tragekugeln und Zwischenstücke oder Kugelkörbe zu einem festenThe new ball bearing is mainly intended for vehicles, dynamos, machines and the like. be turned. A perfect ball bearing consists of two on the ball bearing surfaces grooved races, which do not have any weakening or disruptive uniform hardening Have perforation or recess and which by "support balls and spacers or ball baskets to a solid

ίο Kugellager vereinigt sind. Die Anzahl der Tragekugeln ist beschränkt, da diese lediglich durch exzentrisches Verschieben der beiden Laufringe eingebracht werden können. Um diesem Übelstand abzuhelfen, hat man versucht, mehr Tragekugeln in das Lager hineinzubringen, indem man an den inneren oder äußeren Laufringen Durchbrechungen oder Aussparungen zum Einbringen der Tragekugeln anbrachte; hierbei stellen sich aberίο ball bearings are united. The number of Carrying balls is limited as this can only be achieved by eccentrically moving the two Races can be introduced. In order to remedy this problem, one has tried bring more bearing balls into the bearing by touching the inner or outer races, openings or recesses for inserting the bearing balls attached; here, however, arise

ao bei der Herstellung bedeutende Hindernisse ein, indem die Ringe beim Härten sich verziehen und eine große Anzahl unbrauchbar wird. Um dieses zu verhindern, versuchte man, die Aussparungen nach dem Härten auszuschleifen; hierdurch bekömmt der Ring aber eine ungleiche Spannung, und bei plötzlichen Stößen, die das Lager z. B. bei Kraftwagen auszuhalten hat, springt der Ring.
Alle diese Mängel fallen bei dem neuen Lager fort, weil sich hier kein Ring beim Härten verzieht, da die Lauf ringe keinerlei die gleichmäßige Härtung störende ■ Durchbrechung oder Aussparung haben. An Stelle dessen ist entweder der eine oder es sind beide Kugellauf ringe so dünnwandig gehalten, daß sie etwas federn und hierdurch gestatten, mehr Kugeln einzudrücken, als durch das exzentrische Verschieben der beiden Laufringe möglich ist. Abgesteift werden die Laufringe durch genau zugepaßte Verstärkungsringe. Diese Verstärkungsringe geben, da sie ungehärtet sind, dem Lager noch besondere Widerstandskraft gegen Stöße und verbinden^ gleichzeitig das Springen der inneren Laufringe beim Auftreiben auf die Welle. Die Kugeltrennungsteile oder Kugelkörbe können von beliebiger Bauart sein.ao significant obstacles to manufacture in that the rings warp during hardening and a large number of them become unusable. To prevent this, attempts were made to grind out the recesses after hardening; as a result, however, the ring gets an uneven tension, and in the event of sudden impacts B. has to endure in motor vehicles, the ring jumps.
All these deficiencies are eliminated with the new bearing, because here no ring is distorted during hardening, since the running rings do not have any perforation or recess that would interfere with uniform hardening. Instead, either one or both of the ball race rings are so thin-walled that they spring somewhat and thereby allow more balls to be pushed in than is possible by eccentric displacement of the two races. The race rings are braced by precisely fitted reinforcement rings. These reinforcing rings, since they are not hardened, give the bearing special resistance to impacts and at the same time combine the cracking of the inner race rings when it is driven onto the shaft. The ball separators or ball baskets can be of any type.

Auf der Zeichnung ist das neue, Lager in zwei Ausführungsformen im Längs-.und Querschnitt dargestellt.The drawing shows the new bearing in two versions in longitudinal and cross-section shown.

a, b sind die gehärteten Kugellaufringe, c, d die ungehärteten Verstärküngsringe, e die Tragekugeln und f die Kugeltrennungsteile beliebiger Bauart. a, b are the hardened ball race rings, c, d are the unhardened reinforcement rings, e are the supporting balls and f are any type of ball separator.
