Abstract
Description
Um
eine geradlinige Bewegung in Rotation umzuwandeln wird in verschiedenen
Maschinen eine Kurbel benutzt. Das übliche Schema einer solchen
einkurbeligen Umwandlung ist auf der
Die
Doppelkurbel wird aus zwei Kurbeln „A" und „B" dem gleichen Radius „r" zusammengebaut,
und zwar so, dass „Kopf" der Kurbel „A" als Drehachse für die Kurbel „B" dient. Dabei, falls
die innere Kurbel „A" um einen Winkel „α" um die Achse „O" in eine Richtung
gedreht wird, dann dreht sich die äußere Kurbel „B" entsprechend um
den gleichen Winkel „α" um die Achse „A" in die Gegenrichtung.
Um eine solche entsprechende Rotation der Kurbel „B" in Gegenrichtung
zur Rotation der Kurbel „A" zu gewährleisten,
ist die Kurbel „B" mit einem Zahnrad „P" versehen, das sich
im Innen eines Zahnkranz „Q" wälzt (siehe
Aus
dem grafischen Schema einer solchen Doppelkurbel (siehe
Die eindimensionalen harmonischen Schwingungen des „Kopfes" der Außenkurbel „B" werden durch Einsatz einer Stoßstange „m" für Antrieb einen Kolben „K" benutzt. Damit sind die oben genannten Nachteile der einkurbeligen Umwandlung beseitigt.The One-dimensional harmonic oscillations of the "head" of the outer crank "B" are made by using a bumper "m" for propulsion used a piston "K" eliminates the above-mentioned disadvantages of the single-cranked conversion.
Das
dreidimensionale Schema der Doppelkurbel ist auf der
Allgemein, für Antrieb von mehreren Kolben in einer mehrzylinder Maschine wird entsprechende Menge Kurbeln benutzt, die aus konstruktiven Gründen öfters entlang einer Achse ausgerichtet werden. So entsteht eine Kurbelwelle. Der gleiche Zugang ist auch für die hier vorgeschlagene Doppelkurbel gültig. Dabei bietet die Doppelkurbel reichlich Möglichkeiten für konstruktive Gestaltungen von mehrzylinder Maschinen.Generally, for drive of several pistons in a multi-cylinder machine becomes appropriate Used amount of cranks, which often aligned along an axis for structural reasons become. This creates a crankshaft. The same access is also for the here proposed double crank valid. It offers the double crank plenty of possibilities for constructive Designs of multi-cylinder machines.

Eine
wichtige Charakteristik für
die Kolbenmotoren ist deren Drehmoment. Aus allgemeinen kinematischen
Vorstellungen folgt, dass bei übrigen
gleichen Bedingungen wird der Motor über ein höheres Drehmoment verfügen, der
die kürzeren
Pleuelstangen hat. Diese Behauptung ruht auf nächsten Überlegungen (siehe
Daraus ergibt sich die Kraft „F →(α)": die durch die Pleuelstange „l" auf den effektiven Radius „ref" wirkt: This results in the force "F → (α)": which acts on the effective radius "r ef " by the connecting rod "l":
Die Formeln (3) und (4) bestimmen den Drehmoment „M(α)": The formulas (3) and (4) determine the torque "M (α)":
Der
Winkel „β" ist durch Länge der
Pleuelstange „l" definiert:
Aus Formeln (6) und (8) folgt: oder: From formulas (6) and (8) follows: or:
Es
ist bequemer die Länge „l" in Maßeinheiten „r" darzustellen:
Jetzt hat die Formel (10) folgendes Aussehen: Now formula (10) looks like this:
Die
Formel (12) zeigt, dass je länger
die Pleuelstange „l" ist (d.h. „k" ist entsprechend
größer), desto kleiner
ist der Wert „M(α)", und sein Minimum
beträgt:
Umgekehrt,
bei der möglichst
kürzeren
Pleuelstange: „l" = „r" (d.h. „k" = 1), erreicht der
Wert „M(α)" seinen Maximum:
Das mittlere Drehmoment „M" für einen Zweitakt-Motor ergibt sich durch Ausmittlung den Werten „M(α)" für eine Umdrehung: The mean torque "M" for a two-stroke engine is obtained by calculating the values "M (α)" for one revolution:
Die Formeln (13), (14) und (15) zusammengefasst: Formulas (13), (14) and (15) summarize:
Für einen Viertakt-Motor soll die Ausmittlung den Werten „M(α)" für die zwei Umdrehungen des Motors durchgeführt werden: For a four-stroke engine, the determination of the values "M (α)" for the two revolutions of the engine should be carried out:
Das mittlere Drehmoment eines Viertakters liegt in folgenden Grenzen: The mean torque of a four-stroke engine is within the following limits:
Hier
soll es noch bemerkt werden, dass das auf der Achse „O" vermessene „Ist-Drehmoment" wird etwas kleiner,
als der nach Formeln (12) und (15), beziehungsweise (12) und (17),
berechneter Wert. Dafür
ist der Reibungswiderstand verantwortlich, der durch Wirkung der
Querkraft „F →y(α)" entsteht (siehe
Im
Falle einer Doppelkurbel gibt es keine Pleuelstangen (siehe
