Abstract
Ergometer mit drehzahlübersetzter Wirbelstrombremse und einem Übersetzungsgetriebe mit einer Übersetzungsstufe, wobei die Übersetzungsstufe einen Zahnriemen (1) umfasst.Ergometer with eddy current brake and a transmission gear with a transmission stage, the transmission stage comprising a toothed belt (1).
Description
Die vorliegende Erfindung betrifft ein Ergometer nach dem Oberbegriff des Anspruchs 1.The present invention relates to an ergometer according to the preamble of
STAND DER TECHNIKSTATE OF THE ART
Aus dem Stand der Technik sind verschiedenste Arten von Ergometern bekannt.Various types of ergometers are known from the prior art.
So fallen unter den Begriff des Ergometers sowohl Fahradergometer als auch Handkurbelergometer mit einer oder vorwiegend zwei Getriebestufen zum Antrieb einer Schwungmasse der Wirbelstrombremse.Thus fall under the concept of ergometer both Fahradergometer and manual cycle ergometer with one or predominantly two gear stages for driving a flywheel of the eddy current brake.
Ergometer in Form von Fahrrad- oder Handkurbelergometer werden in der Leistungsphysiologie und in der Sportmedizin zur Analyse von Ausdauerfunktionen und zur Überprüfung einiger Gesundheitsparameter benutzt. Sie werden bei Belastungs-EKG und im Rehabilitationsbereich eingesetzt.Ergometers in the form of bicycle or manual cycle ergometers are used in performance physiology and sports medicine to analyze endurance functions and to check some health parameters. They are used in exercise ECG and rehabilitation.
Eine Wirbelstrombremse nutzt die Wirbelstromverluste einer im Magnetfeld bewegten für Wirbelströme leitfähigen Schwungmasse zur Bremsung. Die Schwungmasse der Wirbelstrombremse wird über Tretpedale oder Handkurbeleinrichtung über ein geeignetes Übersetzungsgetriebe auf die notwendige Drehzahl gebracht. Die Wirkung der Wirbelstrombremse ist von einer hohen Relativgeschwindigkeit zwischen Magnetfeld und Schwungmasse abhängig.An eddy current brake uses the eddy current losses of a moving in the magnetic field for eddy currents conductive flywheel for braking. The flywheel of the eddy current brake is brought on pedal pedals or hand crank device via a suitable transmission gear to the necessary speed. The effect of the eddy current brake is dependent on a high relative speed between the magnetic field and the flywheel.
Um die notwendige Drehzahl an der Schwungmasse zu erreichen, wird auf Lösungen zurückgegriffen, die mit einer oder aber vorwiegend mit zwei Getriebestufen ausgerüstet sind. Die Forderung an diese Getriebestufen ist neben der zu vermeidenden Geräuschentwicklung die schlupffreie Übertragung der vom Anwender eingebrachten Antriebsleistung an den Pedalen auf die Schwungmasse. Die eingebrachte Leistung wird an der durch das Getriebe übersetzten schnellen Welle gemessen und geregelt. Ein nicht zu vermeidender Schlupf bei einer nicht formschlüssigen Kraftübertragungen, wie Reib-Flach- oder Keilriemengetrieben, verfälscht die Messung an der übersetzten Welle. Dies gilt dann besonders, wenn kleinste oder sehr große Leistungen von der Therapie gefordert werden.In order to achieve the necessary speed on the flywheel, resorting to solutions that are equipped with one or predominantly with two gear stages. The requirement of these gear stages is in addition to the noise to be avoided the slip-free transmission of the user introduced drive power to the pedals on the flywheel. The introduced power is measured and regulated at the geared fast shaft. An unavoidable slip in a non-positive force transmissions, such as friction flat or V-belt transmissions, falsifies the measurement on the translated shaft. This is especially true when the smallest or very large benefits are required by the therapy.
AUFGABE DER ERFINDUNGOBJECT OF THE INVENTION
Es ist daher die Aufgabe der vorliegenden Erfindung, ohne Beeinträchtigung der Anwendungsgenauigkeit ein Gerätekonzept zu realisieren, das die Gebrauchstauglichkeit bezüglich der Geräuschentwicklung verbessert, ohne die schlupffreie formschlüssige Kraftübertragung zu verlassen.It is therefore an object of the present invention, without affecting the accuracy of application to realize a device concept that improves the usability in terms of noise, without leaving the slip-free positive power transmission.
LÖSUNG DER AUFGABESOLUTION OF THE TASK
Die Aufgabe wir durch den kennzeichnenden Teil des Anspruchs 1 gelöst.The problem is solved by the characterizing part of
Bei der Erfindung handelt es sich um Ergometer, die vorwiegend in der Medizin und im Rehabilitationsbereich zur Anwendung kommen, in welchem die Geräuschentwicklung der bisher zum Antrieb verwendeten Kettenantriebe stört.The invention relates to ergometers which are predominantly used in medicine and in the field of rehabilitation, in which the noise development of the chain drives previously used for the drive interferes.
Im Einzelnen wird in einem bevorzugten Ausführungsbeispiel in den von der Tret- oder Handkurbel angetriebenen Getriebestufen ein geeigneter Zahnriemen mit geringem oder negativem Temperaturkoeffizienten verwendet. Vorteilhaft hierbei ist der Umstand, dass diese Lösung eine formschlüssige schlupffreie Kraftübertragung auch bei einer Temperaturerhöhung gewährleistet. Dadurch kann auf Spannrollen verzichtet werden.In particular, in a preferred embodiment, a suitable toothed belt with a low or negative temperature coefficient is used in the gear stages driven by the pedal or hand crank. The advantage here is the fact that this solution ensures a positive slip-free power transmission even with a temperature increase. This eliminates the need for tensioners.
Durch die Verwendung von Zahnriemen werden störende Getriebegeräusche im Therapiebetrieb vermieden.The use of toothed belts avoids disturbing transmission noises during therapy operation.
In diesem Zusammenhang kommen sog. Hochleistungszahnriemen zum Einsatz, welche bspw durch einen Aramidzugstrang dazu führen, dass hohe Drehmomente erreicht werden, welche gepaart mit einer langlebigen Laufzeit schlupffrei arbeiten.In this context, so-called. High-performance toothed belts are used, which, for example, lead by an Aramidzugstrang that high torques are achieved, which paired with a long life run without slipping.
