Definitions
- the invention relates to the use of organic compounds as liquids for transmitting frictional forces, in particular in friction wheel transmissions.
- Friction gear or traction gear are devices in which a torque is transmitted by nominal point or line guidance.
- a friction wheel transmission consists of two rollers with parallel or intersecting axes which are in tangential contact with one another, one roller being the drive element and the other being the output element.
- the transmissible torque of such a friction or traction transmission is a direct function of the surface pressure between the rollers and the coefficient of friction of the frictional contact between the roller surfaces.
- special advantages of traction gearboxes are the possibility of continuously changing the gear ratio under full load, without having to interrupt the load while changing the gear ratio, and its high efficiency in the entire gear ratio range.
- a disadvantage of the friction wheel gears is still the much larger dimensions compared to gear gears with the same transferable performance and the same service life. Since the transferable power depends linearly on the circumferential speed of the friction discs at the radius of the friction contact, on the normal force that can be transmitted in the friction contact and on the friction coefficient of the friction contact that can be used for power transmission, all three influencing variables must be chosen as high as possible for the construction of a friction gear.
- the transferable normal force is given by the permissible Hertzian pressure. This determines the service life of the gear unit.
- the circumferential speed is restricted by the size.
- the coefficient of friction that can be used in the transmission is essentially determined by the slip, the peripheral speed of the drive body and the contact pressure between the drive and driven bodies.
- the coefficient of friction is defined as the quotient of the frictional force generated during the friction and the contact pressure between the drive and driven bodies.
- the slip is defined as the absolute value of the quotient from the difference between the two peripheral speeds of the rolling elements and the larger peripheral speed.
- the aim is for the coefficient of friction to increase rapidly with increasing slip in the area of a small slip. This achieves a good efficiency of the traction transmission.
- the aim is for the maximum coefficient of friction to be as large as possible in order to achieve maximum utilization of the power transmission (cf. e.g. D.E.G. Tucker, ant. "Antriebstechnik" 17, No. 6, June 1978).
- the coefficient of friction is determined by the chemical structure of the traction fluid and the operating parameters of the friction gear. These include rolling and sliding speed, normal force in friction contact, macro and micro geometry of the roller surface and thus the geometric shape of the friction contact, temperature in friction contact, drilling friction and skew.
- DE-AS 1 644 925 and DE-AS 1 644 926 describe a large number of organic compounds.
- suitable compounds with a high coefficient of friction for. B. decalin, 1,2-hydrindane, perhydrophenanthrene, perhydrofluorene, perhydrofluoranthene, perhydroazonaphthene, cyclohexyldecalin, primary perhydrocyclopentadiene and methylene hydrophenanthrene.
- a high coefficient of friction of the traction fluid is also associated with high wear of the traction gear.
- the so-called load-bearing capacity of the liquid film is as high as possible. This ensures that there is a certain lubricating effect even in the event of an emergency.
- the object of the invention is therefore to provide traction fluids which have a high coefficient of friction in conjunction with a high load-bearing capacity. This object is achieved with the present invention.

Description
Die Erfindung betrifft die Verwendung von organischen Verbindungen als Flüssigkeiten zur Reibkraftübertragung, insbesondere in Reibradgetrieben.The invention relates to the use of organic compounds as liquids for transmitting frictional forces, in particular in friction wheel transmissions.
Reibrad- oder Traktionsgetriebe sind Vorrichtungen, in welchen ein Drehmoment durch nominale Punkt- oder Linienführung übertragen wird. In vereinfachter Form besteht ein solches Reibradgetriebe aus zwei Walzen mit parallelen oder sich schneidenden Achsen, die in tangentialer Berührung miteinander stehen, wobei eine Walze das Antriebsglied, und die andere das Abtriebsglied darstellt. Das übertragbare Drehmoment eines derartigen Reib- oder Traktionsgetriebes ist eine direkte Funktion der Flächenpressung zwischen den Walzen und Reibungszahl des Reibkontakts zwischen den Walzenoberflächen. Besondere Vorteile von Traktionsgetrieben sind neben einem schwingungsarmen Lauf die Möglichkeit der stufenlosen Veränderbarkeit des Übersetzungsverhältnisses unter voller Last, ohne daß die Belastung während des Änderns der Übersetzung unterbrochen werden muß, sowie ihr hoher Wirkungsgrad im gesamten Übersetzungsbereich.Friction gear or traction gear are devices in which a torque is transmitted by nominal point or line guidance. In a simplified form, such a friction wheel transmission consists of two rollers with parallel or intersecting axes which are in tangential contact with one another, one roller being the drive element and the other being the output element. The transmissible torque of such a friction or traction transmission is a direct function of the surface pressure between the rollers and the coefficient of friction of the frictional contact between the roller surfaces. In addition to a low-vibration run, special advantages of traction gearboxes are the possibility of continuously changing the gear ratio under full load, without having to interrupt the load while changing the gear ratio, and its high efficiency in the entire gear ratio range.
Ein Nachteil der Reibradgetriebe besteht immer noch in den wesentlich größeren Abmessungen gegenüber Zahnradgetrieben bei gleicher übertragbarer Leistung und gleicher Lebensdauer. Da die übertragbare Leistung von der Umfangsgeschwindigkeit der Reibscheiben am Radius des Reibkontakts, von der im Reibkontakt übertragbaren Normalkraft und von der zur Kraftübertragung ausnutzbaren Reibungszahl des Reibkontakts linear abhängt, müssen alle drei Einflußgrößen so hoch wie möglich für die Konstruktion eines Reibradgetriebes gewählt werden. Die übertragbare Normalkraft ist durch die zulässige Hertzsche Pressung gegeben. Diese bestimmt die Lebensdauer des Getriebes. Die Umfangsgeschwindigkeit wird durch die Baugröße eingeengt. Die im Getriebe ausnutzbare Reibungszahl wird im wesentlichen durch den Schlupf, durch die Umfangsgeschwindigkeit des Antriebskörpers und der Anpreßkraft zwischen dem Antriebs- und Abtriebskörper bestimmt.A disadvantage of the friction wheel gears is still the much larger dimensions compared to gear gears with the same transferable performance and the same service life. Since the transferable power depends linearly on the circumferential speed of the friction discs at the radius of the friction contact, on the normal force that can be transmitted in the friction contact and on the friction coefficient of the friction contact that can be used for power transmission, all three influencing variables must be chosen as high as possible for the construction of a friction gear. The transferable normal force is given by the permissible Hertzian pressure. This determines the service life of the gear unit. The circumferential speed is restricted by the size. The coefficient of friction that can be used in the transmission is essentially determined by the slip, the peripheral speed of the drive body and the contact pressure between the drive and driven bodies.
Die Reibungszahl ist definiert als Quotient aus der bei der Reibung entstehenden Reibkraft und der Anpreßkraft zwischen dem Antriebs- und Abtriebskörper. Der Schlupf ist definiert als der absolute Wert des Quotienten aus der Differenz der beiden Umfangsgeschwindigkeiten der Wälzkörper und der größeren Umfangsgeschwindigkeit.The coefficient of friction is defined as the quotient of the frictional force generated during the friction and the contact pressure between the drive and driven bodies. The slip is defined as the absolute value of the quotient from the difference between the two peripheral speeds of the rolling elements and the larger peripheral speed.
Bei Traktionsgetrieben wird angestrebt, daß in dem Bereich eines kleinen Schlupfs die Reibungszahl mit zunehmendem Schlupf rasch ansteigt. Hierdurch erzielt man einen guten Wirkungsgrad des Traktionsgetriebes. Außerdem wird angestrebt, daß die maximale Reibungszahl möglichst groß ist, um eine maximale Ausnutzung der Kraftübertragung zu erreichen (vgl. z. B. D.E.G. Tucker, ant. "Antriebstechnik" 17, Nr. 6, Juni 1978).In the case of traction gears, the aim is for the coefficient of friction to increase rapidly with increasing slip in the area of a small slip. This achieves a good efficiency of the traction transmission. In addition, the aim is for the maximum coefficient of friction to be as large as possible in order to achieve maximum utilization of the power transmission (cf. e.g. D.E.G. Tucker, ant. "Antriebstechnik" 17, No. 6, June 1978).
Die Reibungszahl wird durch die chemische Struktur der Traktionsflüssigkeit und den Betriebsparametern des Reibradgetriebes bestimmt. Dazu zählen Roll- und Gleitgeschwindigkeit, Normalkraft im Reibkontakt, Makro- und Mikrogeometrie der Rollenoberfläche und damit geometrische Gestalt des Reibkontakts, Temperatur im Reibkontakt, Bohrreibung und Schräglauf.The coefficient of friction is determined by the chemical structure of the traction fluid and the operating parameters of the friction gear. These include rolling and sliding speed, normal force in friction contact, macro and micro geometry of the roller surface and thus the geometric shape of the friction contact, temperature in friction contact, drilling friction and skew.
Zur Erhöhung des zu übertragenden Drehmoments ist von diesen Faktoren die Art und Zusammensetzung der Flüssigkeit am leichtesten veränderbar. Es hat deshalb nicht an Versuchen zur Auffindung von Verbindungen zur Verbesserung des Traktionskoeffizienten gefehlt. Die DE-AS 1 644 925 und DE-AS 1 644 926 beschreiben zu diesem Zweck eine Vielzahl von organischen Verbindungen. Als besonders geeignete Verbindungen mit hoher Reibungszahl werden z. B. Decalin, 1,2-Hydrindan, Perhydrophenanthren, Perhydrofluoren, Perhydrofluoranthen, Perhydroazonaphthen, Cyclohexyldecalin, primäres Perhydrocyclopentadien und Methylenhydrophenanthren genannt.Of these factors, the easiest way to change the type and composition of the liquid is to increase the torque to be transmitted. There has been no shortage of attempts to find connections to improve the traction coefficient. For this purpose, DE-AS 1 644 925 and DE-AS 1 644 926 describe a large number of organic compounds. As particularly suitable compounds with a high coefficient of friction, for. B. decalin, 1,2-hydrindane, perhydrophenanthrene, perhydrofluorene, perhydrofluoranthene, perhydroazonaphthene, cyclohexyldecalin, primary perhydrocyclopentadiene and methylene hydrophenanthrene.
Mit einer hohen Reibungszahl der Traktionsflüssigkeit ist aber auch ein hoher Verschleiß des Traktionsgetriebes verbunden. Um den Verschleiß auch bei hoher Reibungszahl möglichst gering zu halten, ist es erforderlich, daß auch die sogenannte Tragfähigkeit des Flüssigkeitsfilms möglichst hoch ist. Dadurch wird erreicht, daß auch im Notlauffall eine gewisse Schmierwirkung vorliegt.A high coefficient of friction of the traction fluid is also associated with high wear of the traction gear. In order to keep the wear as low as possible even with a high coefficient of friction, it is necessary that the so-called load-bearing capacity of the liquid film is as high as possible. This ensures that there is a certain lubricating effect even in the event of an emergency.
Aufgabe der Erfindung ist es deshalb, Traktionsflüssigkeiten bereitzustellen, die eine hohe Reibungszahl in Verbindung mit einer hohen Tragfähigkeit besitzen. Diese Aufgabe wird mit der vorliegenden Erfindung gelöst.The object of the invention is therefore to provide traction fluids which have a high coefficient of friction in conjunction with a high load-bearing capacity. This object is achieved with the present invention.
