  Reibradgetriebe mit Innenberührung und losem, geschlossenem Riemen zwischen den
Reibrädern. 



   Zwischen Reibräder mit   Aussenberührung   legt man vielfach einen losen, geschlossenen Riemen, der an der Berührungsstelle der Reibräder den Auflagedruck auf eine grössere   Fläche   verteilt und den Reibungswiderstand vergrössert. Es hat sich gezeigt, dass diese bei   Reibrädern   mit Aussenberührung bekannte Einrichtung ganz besonders günstig wirkt bei   Reibrädergetrieben   mit Innonberührung, wofür sie bisher nicht verwendet war. Ein solches Getriebe ist in den Figuren 1 und 2 dargestellt. 



   Fig. 1 zeigt das Getriebe in Richtung der Wellen gesehen, Fig 2 gibt einen Querschnitt längs der Wellen.

  Zwischen die sich innen berührenden beiden Räder ist der lose, geschlossene   Riemen r   gelegt, der an der Berührungsstelle wegen der   Innen berührung   der Räder eine besondere, breite Druckfläche bildet. 



   Infolge dieser breiten Druckfläche ist auch eine verhältnismässig grosse Tangentialkraft zwischen den Reibrädern übertragbar ganz in Übereinstimmung mit den bei   gewöhn-   lichen Riemscheiben gemachten Erfahrungen. Der lose zwischen die Reibräder gelegte Riemen kann bei Bedarf ersichtlich leicht ausgewechselt werden.

  Friction gear with internal contact and loose, closed belt between the
Friction wheels.



   A loose, closed belt is often placed between the friction wheels with external contact, which distributes the contact pressure over a larger area at the contact point of the friction wheels and increases the frictional resistance. It has been shown that this device, which is known for friction wheels with external contact, has a particularly favorable effect on friction gear transmissions with internal contact, for which it was not previously used. Such a transmission is shown in FIGS. 1 and 2.



   Fig. 1 shows the transmission seen in the direction of the shafts, Fig. 2 gives a cross section along the shafts.
 EMI1.1
 



  The loose, closed belt r is placed between the two internally touching wheels, which forms a special, wide pressure surface at the point of contact due to the internal contact of the wheels.



   As a result of this wide pressure surface, a relatively large tangential force can also be transmitted between the friction wheels, in accordance with the experiences made with conventional pulleys. The belt, which is loosely placed between the friction wheels, can be easily replaced if necessary.
