Abstract
Description
Technisches GebietTechnical field
Die Erfindung betrifft eine ruhige Gleiskette, wobei der Abstandshalter einen sich nach unten verjüngenden Querschnitt aufweist, der an einen Ende eine größere Breite und an dem anderen Ende eitle kleinere Breite hat, um ein Zusammenpressen des Abstandshalters von den Rollkörpern bei der Kurve zu vermeiden und den Kontaktpunkt der Rollkörper mit dem Abstandshalter im Mittelpunkt zu halten, und wobei der Abstandshalter unter den Verbindungsbändern mit zwei Schultern versehen ist, um die Entformung zu erleichtern.The invention relates to a quiet Track chain, with the spacer tapering downward Cross section, which is larger at one end and at the other End has a smaller width to compress the spacer from the rolling elements to avoid at the curve and the contact point of the rolling elements with to keep the spacer in focus, and being the spacer under the connecting straps has two shoulders to facilitate demolding.

Die zugfeste Schnur
Nachfolgend wird ein Vergleich zwischen der Erfindung und den herkömmlichen Lösungen durchgeführt: (bei den herkömmlichen Lösungen)Below is a comparison between of the invention and the conventional solutions carried out: (with the conventional Solutions)
- 1. Da die zugfeste Schnur und die Führungsnut beide einen quadratischen Querschnitt haben, ist der Reibungswiderstand bei der Zyklusbewegung sehr groß.1. Because the tensile cord and the guide groove both have a square cross-section is the frictional resistance very large in the cycle movement.
- 2. Die Länge des nichtflexiblen Abschnittes der zugfesten Schnur ist größer als die Länge des flexiblen Abschnittes.2. The length of the inflexible section of the tensile cord is greater than the length of the flexible section.
- 3. Wenn die Verbindungsfläche des Verbindungsbandes mit der zugfesten Schnur zu groß ist, weist die zugfeste Schnur einen längeren nichtflexiblen Abschnitt, was beim Rücklauf zu einem großen Widerstand führen kann.3. If the interface of the connecting band with the tensile cord is too large the tensile cord a longer one inflexible section, which when returning to a large resistance to lead can.
- 4. Wenn die Verbindungsfläche des Verbindungsbandes mit der zugfesten Schnur zu klein ist, kann bei der Zyklusbewegung ein Bruch auftreten.4. If the interface of the connecting band with the tensile cord is too small can a break occurs in the cycle movement.
- 5. Wenn der Abstandshalter die Rollkörper in den Kugelpfannen aufnimmt, kann bei der Zyklusbewegung ein großer Widerstand erzeugt werden.5. When the spacer picks up the rolling elements in the ball sockets, can a big one in the cycle movement Resistance are generated.
- 6. Wenn der Abstandshalter die Rollkörper in den Kugelpfannen aufnimmt, ist das Zusammenpressen beim Rücklauf sehr stark.6. When the spacer picks up the rolling elements in the ball cups, is the compression of the return very strong.
- 7. Der Abstandshalter mit Vertiefungen kann zwar den Widerstand bei der Zyklusbewegung reduzieren, jedoch nicht optimieren.7. The spacer with recesses can resist reduce the cycle movement, but do not optimize it.
- 8. Der Abstandshalter mit Vertiefungen kann den Kontaktpunkt mit den Rollkörpern nicht im Mittelpunkt der Rollkörper halten.8. The spacer with recesses can be the contact point with the rolling elements not the focus of the rolling elements hold.
- 9. Der Abstandshalter mit Kugelpfannen oder Vertiefungen für die Rollkörper läßt sich schwer entformen.9. The spacer with ball sockets or recesses for the rolling elements can be difficult to demold.
(bei der Erfindung)(with the invention)
- 1. Die zugfeste Schnur hat einen runden Querschnitt, wodurch der Widerstand reduziert wird.1. The tensile cord has a round cross-section, whereby the resistance is reduced.
- 2. Die Querschnittsfläche eines Quadrates ist um 21% größer als die einer Kugel. Die Flächenreibung ist jedoch größer als das Zehnfache der Linearreibung. Daher ist eine runde zugfeste Schnur besser als eine guadratische zugfeste Schnur.2. The cross-sectional area of a square is 21% larger than that of a bullet. The surface friction is however larger than ten times the linear friction. Therefore, a round tensile cord better than a square tensile cord.
- 3. Die Verbindungsfläche des Verbindungsbandes mit der zugfesten Schnur und dem Abstandshalter ist das Zweifache der Querschnittsfläche der zugfesten Schnur, was die optimale Wirkung erreichen kann.3. The interface the connecting band with the tensile cord and the spacer is twice the cross-sectional area of the tensile cord what can achieve the optimal effect.
- 4. Der Abstandshalter weist Schultern auf, wodurch bei der Zyklusbewegung ein großer Wiederstand und ein starkes Zusammenpressen vermieden werden können.4. The spacer has shoulders, which helps with the cycle movement a large Resistance and a strong compression can be avoided.
- 5. Kontaktpunkt der Rollkörper mit dem Abstandshalter kann im Mittelpunkt gehalten werden.5. Contact point of the rolling elements with the spacer can be held in the center.
- 6. Die Entformung des Abstandshalters ist leicht.6. The removal of the spacer is easy.
- 7. Die Gebrauchskosten werden reduziert.7. The usage costs are reduced.
- 8. Der Gebrauchswert wird erhöht.8. The use value is increased.
Aufgrund der obengenannten Tatsachen entspricht die Erfindung in ihrer Verfügbarkeit, Fortschrittlichkeit und Neuheit vollauf den Anforderungen für ein Gebrauchsmuster.Due to the above facts corresponds to the invention in its availability, progressiveness and novelty fully meets the requirements for a utility model.
