Description

Reibrolle für Reibräderwechselgetriebe. Bei den bisher bekannten Reibrollen machte sich der Übelstand geltend, daß nur der mittlere Teil der Reibrolle sich auf den Reibscheiben abrollen konnte, während der übrige Teil ein Schleifen auf den Reibscheiben bewirkte, wodurch außer einer starken Abnutzung der Reibrolle die Kraftübertragung sehr beeinträchtigt wurde, und zwar besonders dann, wenn es sich um Übertragung größerer Kräfte handelte.Friction roller for friction gear change gears. With the previously known friction rollers the disadvantage asserted itself that only the middle part of the friction roller Could roll on the friction disks, while the remaining part was a grinding on caused the friction disks, which apart from severe wear of the friction roller the Power transmission has been severely impaired, especially when it is was about the transfer of greater powers.

In der Zeichnung ist der Erfindungsgegenstand dargestellt, und zwar zeigt Fig. = die Reibrolle in Verbindung mit zwei Reibscheiben, Fig. 2 den Grundriß der Reibrolle.In the drawing, the subject of the invention is shown, namely Fig. = shows the friction roller in connection with two friction disks, Fig. 2 shows the plan the friction roller.

Neben der bekannten vollen Reibrolle a sind die beiden Rollenhälften b und c gelagert. Diese sind mit den Ansätzen d versehen, gegen die sich die Federn e, f legen.In addition to the well-known full friction roller a, the two roller halves b and c are mounted. These are provided with the shoulders d, against which the springs e, f lie.

Die Wirkungsweise dieser Reibrolle ist folgende: Es sei die Reibscheibe g' die treibende, wobei die Reibrolle a die Übertragung auf die Reibscheibe h vermittelt. Die Reibrolle a wird sich in der Mittellage genau auf den beiden Reibscheiben g und h abrollen. Wäre die Reibrolle b, c nicht geteilt, sondern bestände ebenfalls aus einer vollen Rolle, so müßte beim Verschieben der Reibrolle aus der Mittellage ein teilweises Schleifen der Reibrolle b, c eintreten, denn inbezug auf die Reibscheibe g müßte sich die Reibrolle b schneller oder langsamer und in bezug auf die Reibscheibe h umgekehrt langsamer oder schneller abrollen als die Reibrolle a. Da jedoch die Reibrolle b, c in der Mitte geteilt ist, so kann sich die eine Hälfte b auf der Scheibe g und die andere Hälfte c auf der Reibscheibe h abrollen, ohne zu schleifen, d. h. also, die Reibrollenhälfte b wird sich je nach der Richtung des Schubes schneller bzw. langsamer bewegen als die Reibrollenhälfte c. Nach einer halben Umdrehung der Reibrolle tritt der entgegengesetzte Fall ein, indem sich jetzt die Reibrollenhälfte b langsamer bzw. schneller bewegt als die Reibrollenhälfte c usw. Durch diese Anordnung einer einfach geteilten Reibrolle neben der vollen Reibrolle wird somit das Schleifen der Reibrolle zum Teil aufgehoben, indem man- die Breite der Reibrolle so klein als möglich wählt.The mode of action of this friction roller is as follows: Let the friction disk g 'be the driving force, with the friction roller a conveying the transmission to the friction disk h. The friction roller a will roll exactly on the two friction disks g and h in the middle position. If the friction roller b, c were not divided, but also consisted of a full roller, then when the friction roller was shifted from the central position, the friction roller b, c would have to be partially rubbing, because in relation to the friction disc g, the friction roller b would have to move faster or slower and with respect to the friction disk h, conversely, roll slower or faster than the friction roller a. However, since the friction roller b, c is divided in the middle, one half b can roll on the disc g and the other half c on the friction disc h without grinding, that is to say, the friction roller half b will move depending on the Move the direction of the thrust faster or slower than the friction roller half c. After half a revolution of the friction roller, the opposite occurs, in that the friction roller half b now moves slower or faster than the friction roller half c etc. This arrangement of a simply divided friction roller next to the full friction roller thus partially eliminates the grinding of the friction roller, by choosing the width of the friction roller as small as possible.

Handelt es sich um Übertragung größerer Kräfte, so kann man außer der Reibrolle a und der geteilten Reibrolle b, c noch eine oder mehrere Reibrollen daneben anordnen.If it is a question of the transfer of greater forces, one can except the friction roller a and the divided friction roller b, c have one or more friction rollers arrange next to it.
