Description
Lagermetall Die Erfindung betrifft eine Lagermetalllegierung auf der Grundlage Cadmium. Es sind Cadmiumlegierungen für Lagerzwecke bekannt, die -beispielsweise mit Nickel, Kupfer, Magnesium, Silber odeZink vergütet sind. Diese Legierungen, die einen verhältnismäßig hohen Cadmiumgehalt aufweisen, sind als Lagerwerkstoffe ,geeignet. Erhöht man jedoch in solchen Legierungen unter Verringerung des Cadmiumgehaltes die Menge der Vergütungszusätze, so erhält man so hohe Härtewerte, daß die Legierungen praktisch nur noch für doppelt gehärtete Wellen Verwendung finden kösmen.Bearing metal The invention relates to a bearing metal alloy on the Based on cadmium. There are known cadmium alloys for storage purposes, for example are tempered with nickel, copper, magnesium, silver or zinc. These alloys, which have a relatively high cadmium content are used as bearing materials ,suitable. However, if you increase such alloys while reducing the cadmium content the amount of tempering additives, the hardness values obtained are so high that the alloys can practically only be used for double hardened shafts.
Es hat sich nun gezeigt, daß man zumindest gleich gute, in den meisten Fällen jedoch bessere Lagermetalle erhält, wenn man zu Cadmium o,oi bis 20 o'o Zirkon als Härtungselement zufügt. Diese Cadmiumlegierungen, die außerdem noch Blei in Mengen bis zu io % enthalten können, zeigen starken Silberglanz, und infolge ihrer günstigen Härteeigenschaften erübrigt sich bei -ihrer Verwendung als Lagerwerkstoff die teuere und umständliche Doppelhärtung des Wellenmaterials.It has now been shown that you are at least equally good in most In cases, however, better bearing metals are obtained if one adds o, oi to 20 o'o zircon to cadmium as a hardening element. These cadmium alloys, which also contain lead in Amounts can contain up to 10%, show strong silver sheen, and as a result of them Favorable hardness properties are unnecessary when they are used as a bearing material the expensive and cumbersome double hardening of the shaft material.
