Abstract

The belt pulley is particularly of the V-belt type for high-speed drives, used esp. for I.C. engine auxiliary drives. The pulley (1) comprises two or more components of sheet-metal (2, 3) rolled into shape together. A pot-shaped portion (8) joins onto the portion contg. the belt grooves (6), whose dia. is roughly that of the groove bases. The design avoids noise generation due to vibration at high speeds.

Description

Riemenscheibe Die Erfindung betrifft eine Riemenscheibe, insbesondere eine Keilriemenscheibe für hochtourige Antriebe Bel Riemenscheiben, insbesondere bei aus Blech gefertigten topffö.rmigen Riemenscheiben für hochtourige Antriebe treten erhebliche Geräusche verursachende Vibrationen auf Aufgabe der Erfindung ist es, eine Riemenscheibe, insbesondere eine Keilriemenscheibe für hochtourige Antriebe zu schaffen, die diesen Nachteil nicht aufweist Erfindungsgemäß wird diese Aufgabe dadurch gelöst, daß die Riemenscheibe durch wenigstens zwei gemeinsam gerollte Bleche gebildet wird In einer zweckmässigen Ausführungsform der Erfindung umfasst die Riemenscheibe wenigstens einen Nuten zur Aufnahme der Riemen aufweisenden Abschnitt, an dem sich ein topfförmiger Abschnitt anschließt und wobei der Durchmesser des topfförmigen Abschnittes in etwa dem Durchmesser des Nutengrundes der die Riemen aufnehmenden Nuten entspricht Der mit der Erfindung insbesondere erzielte Vorteil besteht darin, daß beim Betrieb der Riemenscheibe aufgrund der molekularen Reibung zwischen den Blechen eine teilweise Umwandlung der Schwingungsenergie in Wärme stattfindet, wodurch die Geräuschbildung verringert wird In der Zeichnung ist die Erfindung anhand einer topfförmigen Riemenscheibe in einer beispielsweisen Ausführungsform dargestellt. Pulley The invention relates to a pulley, in particular a V-belt pulley for high-speed drives Bel pulleys, in particular for pot-shaped belt pulleys made of sheet metal for high-speed drives occur significant noise-causing vibrations object of the invention is to use a pulley, especially a V-belt pulley for high-revs To create drives that do not have this disadvantage The object is achieved in that the pulley is rolled together by at least two Sheet metal formed is included in an expedient embodiment of the invention the pulley has at least one groove for receiving the section having the belt, which is followed by a cup-shaped section and the diameter of the cup-shaped section approximately the diameter of the groove bottom of the belt receiving grooves corresponds to the advantage achieved in particular with the invention is that during operation of the pulley due to molecular friction a partial conversion of the vibration energy into heat takes place between the sheets, whereby the noise is reduced. In the drawing, the invention is based on a cup-shaped pulley shown in an exemplary embodiment.

Die mit 1 bezeichnete topfförmige Riemenscheibe, die als Keilriemenscheibe ausgebildet ist, wird durch zwei Bleche 2 und 3 gebildet und weist an ihrer Stirnseite Befestigungslöcher 5 auf, mittels der die Riemenscheibe 1 direkt oder indirekt z«Bn an der Kurbelwelle einer Brennkraftmaschine zum Antrieb von Nebenaggregaten angeflanscht werden kann Die die Keilriemen aufnehmenden Nuten snd mit 6, der Abschnitt der Riemenscheibe 1, über den sich die Nuten 6 erstrecken, ist mit 7 und der durch eine Mantelfläche 9 gebildete topfförmige Abschnitt der Riemenscheibe 1 ist mit 8 bezeichnet Der Durchmesser des topfförmigen Abschnittes 8 entspricht in etwa dem Durchmesser des Nutengrundes 10 der die Keilriemen aufnehmenden Nuten 6 Die Fertigung der Riemenscheibe 1 erfolgt durch Tiefziehen zur Erzielung der Topfform und anschließendem gemeinsamem Rollen der uberelnanderliegenden Bleche 2 und 3 zur Herstellung der die Keilriemen aufnehmenden Nuten 6 Leerseite The cup-shaped pulley designated by 1, which is called a V-belt pulley is formed is formed by two sheets 2 and 3 and has on its end face Mounting holes 5, by means of which the pulley 1 directly or indirectly z «Bn Flanged to the crankshaft of an internal combustion engine to drive ancillary units The grooves that hold the V-belts snd with 6, the section of the belt pulley 1, over which the grooves 6 extend, is with 7 and that through a lateral surface 9 formed cup-shaped section of the pulley 1 is denoted by 8 The diameter of the cup-shaped section 8 corresponds approximately to the diameter of the groove base 10 of the grooves 6 receiving the V-belts. The belt pulley 1 is manufactured by deep drawing to achieve the pot shape and then rolling together of the overlying sheets 2 and 3 for the production of the V-belts receiving Grooves 6 Blank page
