Anordnung zum Befestigen eines scheibenförmigen Teils auf der Welle einer Maschine Arrangement for fastening a disc-shaped part on the shaft of a machine

Die Neuerung betrifft eine Anordnung zum Befestigen eines scheibenförmigen Teils, vorzugsweise einer aus Blech bestehenden Riemenscheibe, auf der Welle einer Maschine.The innovation relates to an arrangement for attaching a disk-shaped Partly, preferably a belt pulley made of sheet metal, on the shaft of a machine.

Robert Bosch GmbH R.-Nr. 8842Robert Bosch GmbH R. No. 8842

Stuttgart 2.3.1967 Rs/EpStuttgart 2.3.1967 Rs / Ep

Der Neuerung liegt die Aufgabe zugrunde, eine Anordnung zu schaffen, die eine einfache und sichere Befestigung eines scheibenförmigen Teils auf einer Welle ermöglicht.The innovation is based on the task of creating an arrangement which a simple and secure attachment of a disc-shaped Partly on a wave made possible.

Die Aufgabe wird rieuerungsgemäß dadurch gelöst, daß das scheibenförmige Teil zwischen einer auf der Welle verschraubbaren Mutter ■und einem an der Welle vorgesehenen Anschlag fest eingespannt ist.The object is achieved according to the invention in that the disk-shaped Part is firmly clamped between a nut that can be screwed onto the shaft ■ and a stop provided on the shaft.

Jn der Zeichnung ist als AusfUhrungsbeispiel des Gegenstandes der Neuerung eine Anordnung zum Befestigen einer Riemenscheibe und eines Lüfters auf der Welle dargestellt. Es zeigen:In the drawing is an exemplary embodiment of the subject The innovation is an arrangement for attaching a pulley and a fan on the shaft. Show it:

Fig. 1 einen Längsschnitt der Anordnung undFig. 1 is a longitudinal section of the arrangement and

1'"1Ig. 2 einen Schnitt der Anordnung nach der Linie II-II in Fig.1 '" 1 Ig. 2 a section of the arrangement along the line II-II in Fig.

Mit 10 ist eine aus Blech bestehende Riemenscheibe und mit 11 ein scheibenförmiger, ebenfalls aus Blech bestehender Lüfter bezeichnet, die auf einer Welle 12 zwischen einer Mutter IJ und einem festen Anschlag derart eingespannt sind, daß eine reibschlüssige Verbindung zwischen der Welle 12 und der Riemenscheibe 10 sowie dem Lüfter 11 entsteht. Der feste Anschlag besteht aus einem Anschlagring YJ, der sich gegen einen Sprengring 15 abstützt. Der Sprengring 15 greift in eine Ringnut l6 der Welle 12 ein und wird von einem Fortsatz I7 des Anschlagrings 14 in der Ringnut gehalten. Zwischen der Mutter YJ und der Riemenscheibe 10 sind ein Distanzring l8 und eine Federscheibe 19 angeordnet.10 denotes a pulley made of sheet metal and 11 denotes a disk-shaped fan, also made of sheet metal, which are clamped on a shaft 12 between a nut IJ and a fixed stop in such a way that a frictional connection between the shaft 12 and the pulley 10 as well as the fan 11 arises. The fixed stop consists of a stop ring YJ, which is supported against a snap ring 15. The snap ring 15 engages in an annular groove 16 of the shaft 12 and is held in the annular groove by an extension I7 of the stop ring 14. A spacer ring 18 and a spring washer 19 are arranged between the nut YJ and the pulley 10.

Um die Schraubverbindung im Reparaturfall leicht lösen zu können, besteht zwischen der Riemenscheibe 10 und der Welle 12 eine formschlüssige Verbindung 20, wie aus Fig. 2 ersichtlich ist. DieseIn order to be able to easily loosen the screw connection in the event of a repair, there is a form-fitting between the belt pulley 10 and the shaft 12 Connection 20, as can be seen from FIG. This

Stuttgart 2.3.I967 Rs/EpStuttgart 2.3.I967 Rs / Ep

formschlüssige Verbindung 20 ist zur Übertragung des Drehmomentes zwischen der Riemenscheibe und der Welle nicht erforderlich, jedoch erleichtert sie die Demontage der Riemenscheibe, da in dem Augenblick, in dem der Anpreßdruck beim Lockern der Schraube unter etwa 1 mkp absinkt, die Reibungskraft zwischen dem Anschlagring und dem Lüfter 11 bzw. der festgehaltenen Riemenscheibe 10 nicht mehr zum Festhalten der Welle ausreicht, d.h. die Welle würde sich beim Drehen der Mutter I3 mitdrehen. Bei Verwendung eines motorisch angetriebenen Schraubenschlüssels ist die formschlüssige Verbindung zum Anziehen und Lockern der Schraube wegen des bei hoher Schraubgeschwindigkeit auftretenden großen Trägheitsmomentes nicht erforderlich. Positive connection 20 is to transmit the torque between the pulley and the shaft is not required, however it facilitates the dismantling of the pulley, because at the moment in which the contact pressure drops below about 1 mkp when the screw is loosened, the frictional force between the stop ring and the fan 11 or the held pulley 10 is no longer sufficient to hold the shaft, i.e. the shaft would rotate turn when the nut I3 is turned. When using a motorized powered wrench is the positive connection for tightening and loosening the screw because of the high screwing speed occurring large moment of inertia is not required.
