Description

Fiir Rollenlager bestimmte Rollen und Ringe aus Chromnickelstahl.
Zur Herstellung von Rollenlagern verwendet man bisher Rollen und Ringe aus hochkohlenstoffhaltigem Chromstahl oder einsatzgehältetem Stahl. Die Rollen und Ringe aus einsatzgehärteten Stählen haben im Kern durchwegs einen Kohlenstoffgehalt von etwa 0'15 bis 0'2%. Sie halten infolge ihrer geringen Kernfestigkeit nur niedrigen Drücken stand. Die Chromstahlrollen und Chromstahlringe haben den Nachteil, dass die äussere Schichte vielfach zum Abblättern oder Abplatzen neigt. Diese Nachteile werden der Erfindung gemäss dadurch vermieden, dass man zur Herstellung der Rollen und Ringe von Rollenlagern Chromnickelstähle verwendet, die bei 0'5 bis 2% Chrom und 1 bis 5% Nickel einen Kohlenstoffgehalt von 0'45 bis 1% aufweisen. Sehr gute Ergebnisse wurden z.
B. erreicht bei Verwendung von Stählen, die 0-75% C, 1-5% Cr und 20/nui Ni oder 0#5% C, 1#3% Cr, 4#5% Ni, 0#9% W und 0#1% V enthalten.
Um die Verschleissfestigkeit der Ringe und Rollen zu erhöhen, können die Stähle im Einsatz gehärtet werden. Diese Rollen und Ringe haben gegenüber den bisher verwendeten einsatzgehärteten den Vorteil, dass sie infolge ihrer grossen Kernfestigkeit hohen Drücken standhalten und nicht zum Abplatzen neigen.
An dem Wesen der Erfindung wird nichts geändert durch den Zusatz von die Festigkeit verbessernden üblichen Legierungskomponenten.

Chrome-nickel steel rollers and rings designed for roller bearings.
To date, rollers and rings made of high-carbon chromium steel or case-retained steel have been used to manufacture roller bearings. The core of the rollers and rings made of case-hardened steels has a carbon content of around 0.15 to 0.2%. Due to their low core strength, they withstand only low pressures. The chrome steel rollers and chrome steel rings have the disadvantage that the outer layer often tends to peel or flake off. According to the invention, these disadvantages are avoided by using chromium-nickel steels for the manufacture of the rollers and rings of roller bearings which have a carbon content of 0'45 to 1% with 0.5 to 2% chromium and 1 to 5% nickel. Very good results were e.g.
B. achieved when using steels that contain 0-75% C, 1-5% Cr and 20 / nui Ni or 0 # 5% C, 1 # 3% Cr, 4 # 5% Ni, 0 # 9% W and 0 # 1% V included.
In order to increase the wear resistance of the rings and rollers, the steels can be hardened in use. These rollers and rings have the advantage over the case-hardened ones previously used that, due to their high core strength, they withstand high pressures and do not tend to flake off.
The essence of the invention is not changed by the addition of the usual alloy components which improve strength.
