Abstract

Kühlgebläse für Brennkraftmaschinen sind üblicherweise auf einer Lüfterwelle mittels eines Lagers gelagert, welches mit der Lüfterwelle und der Lüfternabe durch einen Presssitz verbunden sind. Die Lüfterwelle ist häufig an einem Steuergehäuse in einem vorderen Bereich der Brennkraftmaschine angebracht.Cooling fans for internal combustion engines are usually on a fan shaft supported by a bearing, which with the fan shaft and the fan hub by a press fit are connected. The fan shaft is often on one Control housing in a front region of the internal combustion engine appropriate.

Es wird ein Gebläsezusammenbau mit einer Lüfterwelle (16), einem Träger (12) mit einer Gewindebohrung und einer Lagerbüchse (14) zur Befestigung der Lüfterwelle (16) an dem Träger (12) vorgeschlagen. Die Lagerbüchse (14) ist selbstsichernd ausgebildet und weist einen zylindrischen Hauptabschnitt (23) mit einem ein Gewinde aufweisenden Umfang auf, mittels dem die Lagerbüchse (14) in die Gewindebohrung des Trägers (12) eingeschraubt werden kann, wobei der Hauptabschnitt (23) eine erste konzentrische Bohrung (24), welche mit dem Umfang der Lüfterwelle (16) derart korrespondiert, dass ein normaler Presssitz zwischen der Lagerbüchse (14) und der Gebläsewelle (16) hergestellt werden kann, und eine zweite Bohrung (32) reduzierten Durchmessers, worin ein Verformungssitz zwischen der Lagerbüchse (14) und der Lüfterwelle (16) hergestellt werden kann, und nah dem Bereich (32) reduzierten Durchmessers eine Mehrzahl von Entlastungsaussparungen (36) aufweist, so dass der Hautabschnitt (23) sich aufgrund des Verformungssitzes zwischen der Lagerbüchse (14) und der Lüfterwelle (16) derart aufweiten kann, dass ein Verformungssitz zwischen dem ein Gewinde aufweisenden Umfang des Hauptabschnitts (23) und der Gewindebohrung (38) des Trägers (12) hergestellt wird.

Figure 00000001
A blower assembly with a fan shaft (16), a carrier (12) with a threaded bore and a bearing bush (14) for fastening the fan shaft (16) to the carrier (12) is proposed. The bearing bush (14) is self-locking and has a cylindrical main portion (23) with a threaded circumference, by means of which the bearing bush (14) can be screwed into the threaded bore of the carrier (12), wherein the main portion (23) a a first concentric bore (24) corresponding to the circumference of the fan shaft (16) such that a normal interference fit can be made between the bearing sleeve (14) and the fan shaft (16) and a second reduced diameter bore (32) a deformation fit between the bearing sleeve (14) and the fan shaft (16) can be made, and close to the reduced diameter portion (32) has a plurality of relief recesses (36), so that the skin portion (23) due to the deformation fit between the bearing bush (14) and the fan shaft (16) can expand such that a deformation fit between the threaded circumference of the Hauptabschn itts (23) and the threaded bore (38) of the carrier (12) is produced.
