Abstract

The spur wheel (1) bearing comprises two axially adjacent arranged angular ball bearings (3,4). A circlip (7) is arranged between outer bearing rings (5,6) of the angular ball bearings in an axial manner. An inner ring (10) of the former angular ball bearing is supported on a shaft shoulder (9), and another inner ring (8) of the latter angular ball bearing is supported on a shaft nut (11). The inner rings are tightened according to a shaft (2). A required axial pre-loading force is generated between the outer bearing rings of the angular ball bearings by a defined oversize of the circlip.

In vorteilhafter Weise ist der Sprengring gestuft (mit gestufter Breite) ausgeführt und dient gleichzeitig der axialen Fixierung des Stirnrades. Hierbei ist vorgesehen, dass der geometrische Stirnflächenversatz der Schrägkugellager vor dem Zusammenbau bzw. der Montage durch eine definierte Prüfkraft ermittelt wird.In Advantageously, the snap ring is stepped (with stepped width) accomplished and at the same time serves for the axial fixation of the spur gear. in this connection is provided that the geometric end face offset of the angular contact ball bearings determined before assembly or assembly by a defined test load becomes.

Ferner wird die Tiefe zwischen der Anlagefläche der Wellenmutter und der Anlagefläche der Schrägkugellager gemessen; die Wellenmutter wird so stark angezogen, bis sie an einer Wellenschulter zur Anlage kommt.Further is the depth between the contact surface of the shaft nut and the contact surface the angular contact ball bearing measured; the shaft nut is tightened until it touches a Wave shoulder comes to the plant.

Durch das definierte Übermaß am Sprengring zwischen den Lageraußenringen der Schrägkugellager ist die erforderliche axiale Vorspannung einstellbar. Dies bedeutet, dass die Wellenschulter, an der der Lagerinnenring des ersten Schrägkugellagers anliegt, als Überlastschutz fungiert und eine definierte Vorspannung bewirkt. Hierbei ist der Gesamtstirnflächenversatz inklusive der Sprengringdicke um einen definierten Betrag größer, als das Tiefenmaß von der Anlagefläche des Innenrings des ersten Schrägkugellagers bis zur Wellenmutteranlagefläche.By the defined excess at the snap ring between the bearing outer rings the angular contact ball bearing is the required axial preload adjustable. This means, that the shaft shoulder, on which the bearing inner ring of the first angular contact ball bearing applied as overload protection acts and causes a defined bias. Here is the Total face offset including the snap ring thickness by a defined amount greater than the depth gauge of the contact surface the inner ring of the first angular contact ball bearing to the shaft nut contact surface.

Durch die erfindungsgemäße Konzeption ist auf einfache und kostengünstige Weise eine definierte Vorspannkraft mit geringer Streubreite einstellbar; des weiteren wird der Montageprozess vereinfacht, wobei in vorteilhafter Weise keine Muttersicherung erforderlich ist. Es entsteht ein spielfreies System, welches einen geringen Bauraum benötigt und vom Setzverhalten im Schraubverband nicht signifikant beeinflussbar ist.By the conception according to the invention is easy and inexpensive Way a defined biasing force with a small spread adjustable; of Furthermore, the assembly process is simplified, wherein advantageously Way no mother protection is required. It creates a play-free System, which requires a small space and the setting behavior in a bolted association is not significantly influenced.
