Der Außenring 3 ist beiderseitig an seinen Rändern mit Ausdrehungen 5, 5' versehen, und seine Mantelfläche ist konvex gekrümmt, mit einem Krümmungsradius von mindestens dem zweifachen maximalen Außenringdurchmesser. Ein dünnwandiger Gehäusering 6 aus gehärtetem Stahl mit zylindrischer Bohrung umschließt den Außenring 3 und ragt mit seinen Stirnflanschen 7, T in die Ausdrehungen 5, 5', deren axiale Tiefe so gewählt ist, daß zwischen den Stirnflanschen 7, T des Gehäuseringes 6 und den diesen gegenüberstehenden Stirnflächen des Außenringes 3 ein Spiel von einigen Zehntelmillimetern verbleibt.Fig. 1 shows a cylindrical roller bearing with a rimless inner ring 1, cylindrical rolling elements 2 and an outer ring 3 with fixed ribs 4, 4 '. The outer ring 3 is provided with recesses 5, 5 'on both sides at its edges, and its outer surface is convexly curved with a radius of curvature of at least twice the maximum outer ring diameter. A thin-walled housing ring 6 made of hardened steel with a cylindrical bore surrounds the outer ring 3 and protrudes with its end flanges 7, T into the recesses 5, 5 ', the axial depth of which is chosen so that between the end flanges 7, T of the housing ring 6 and these opposite end faces of the outer ring 3 a game of a few tenths of a millimeter remains.
Bei dieser Lagerausführung kann sich der Außenring 3 in der Bohrung des Gehäuseringes 6 abwälzend einstellen, ohne daß dabei eine nennenswerte Gleitreibung eintritt. Durch den großen Radius der Mantelfläche des Außenringes 3 ist das Schmiegungsverhältnis zwischen der zylindrischen Gehäuseringbohrung und der Mantelfläche des Außenringes so günstig, daß die spezifischen Belastungen weit unter dem zulässigen Wert bleiben.In this type of bearing, the outer ring 3 can roll in the bore of the housing ring 6 set without any significant sliding friction occurring. Due to the large radius of the outer surface of the outer ring 3 is the oscillation ratio between the cylindrical housing ring bore and the surface of the outer ring so favorable that the specific loads are well below the permissible Remain worth.
