Description
Vorrichtung zur Messung der Torsion eines einseitig gelagerten zylindrischen Hohlkörpers Gegenstand der vorliegenden Erfindung ist t eine Vorrichtung zur Messung des Torsion eines ein seitig gelagerten zylindrischen Hohlkörpers mit einem zentral und axial angeordneten Stab, der am freien Ende des Hohlkörpers starr befestigt ist.
Ist die Torsion einer Hohlwelle an dem Teil derselben, an dessen Ende der Stab austritt, geringer als am anderen Teil und ist das Ausmass der Torsion nur bei dem letzteren von Interesse, z.B. wenn eine Hohlwelle zwischen der Stelle ihres Antriebes und der Stelle ihrer Energieabgahe gelagert ist und man den Energieverlust, der an diesem Lager ent ste.ht, bei der Messung weitgehend eliminieren will, so kann man die Torsion dieses Teilstückes der Hohlwelle aus der Messung g ausschliessen, in, dem man eine Hohlwelle verwendet, die in dem Teil, an dem die Lagerung angeordnet ist, ein gegenüber der Welle gleitbar angeordnetes Rohr entsprechender Länge trägt,
das an seinem dem offenen Ende der Welle abgewandten Ende starr mit der Welle verbunden ist und somit an der Torsion des zu messenden Wellenteils nicht teilnimmt.
Erfindungsgemäss ist die Vorrichtung dadurch gekennzeichnet, dass der einseitig gelagerte zylindrisohe Hohlkörper im Bereich des Lagers mit einem konzentnisch und gegenüber dem Hohlkörper gleitbar angeordneten Rohr ausgestattet ist, das an seinem der Befestigungsstelle des Stabes zugekehrten Ende mit dem Hohlkörper starr verbunden ist.
Hierdurch wird erreicht, dass das zusätzliche Rohr an der Torsion des zu messenden Hohlkörperteils nicht teilnimmt. Man misst also den Torsionswinkel als den Winkel, der sich zwischen dem an der Torsion nicht teilnehmenden Rohr und dem Stab einstellt.
Die durch das Lager bedingten Energieverluste werden aus der Messung ausgeschlossen.
Im Falle eines auf Torsion beanspruchten, aber ruhenden Rohres ist dieser Winkel ohne weiteres ablesbar, im Falle einer sich dreh enden Welle erscheint er als Drehwinkel, zu dessen Messung man zweckmässig eine hierfür bekannte Vorrichtung, z. B. einen elektronischen Drebwinkelmesser, verwendet.
Die Torsionsmessung kann z. B. als Mass für die auf das Rohr wirkenden Drehkräfte oder für die auf die Welle der Drehrichtung entgegengesetzt wirkenden Kräfte bzw. deren Veränderungen dienen.
Ein Ausführungsbeispiel der Erfindung wird im folgenden anhand der Zeichnung näher beschrieben.
Die Zeichnung stellt einen Querschnitt durch eine Torslionsmessvorrichtung dar, die an einem Flüssigkeitsbehälter angeordnet ist und hier zum Messen der Viskosität bzw. Viskositätsänderung einer Flüs siigkeit eingesetzt ist.
Eine den Hohlkörper darstellende Hohlwelle 1 dient zum Antrieb von in die Flüssigkeit eintauchenden Rührflügeln. Die Hohlwelle mit dem Einsatzrohr 2, das bei 3 mit der Hohlwelle starr verbunden ist, wird über ein Zahnrad 4 durch den Motor 5 angetrieben, ist bei 6 gelagert, trägt am anderen Ende Rührflügel 7, taucht in einen mit Flüssigkeit 8 gefüllten Rührbehälter 9 ein und ist durch die Stopfbuchse 10 durch den Deckel des Behälters 9 hin durchgeführt. Der Winkel, der sich zwischen dem Einsatzrohr 2 und dem Stab 11, der am freien Ende der Hohlwelle starr befestigt ist, einstellt, kann als Mass für die Viskosität der Flüssigkeit 8 dienen.
Device for measuring the torsion of a cylindrical hollow body mounted on one side The present invention relates to a device for measuring the torsion of a cylindrical hollow body mounted on one side with a centrally and axially arranged rod which is rigidly attached to the free end of the hollow body.
If the torsion of a hollow shaft is less at the part of the same at the end of which the rod emerges than at the other part and is the extent of the torsion only of interest in the latter, e.g. If a hollow shaft is stored between the point of its drive and the point of its energy output and you want to largely eliminate the energy loss that occurs at this bearing during the measurement, you can exclude the torsion of this section of the hollow shaft from the measurement g , in which a hollow shaft is used which, in the part on which the bearing is arranged, carries a tube of a corresponding length, arranged so as to be slidable with respect to the shaft,
which is rigidly connected to the shaft at its end facing away from the open end of the shaft and thus does not participate in the torsion of the shaft part to be measured.
According to the invention, the device is characterized in that the cylindrical hollow body mounted on one side is equipped in the area of the bearing with a tube which is concentrically and slidably arranged relative to the hollow body and which is rigidly connected to the hollow body at its end facing the attachment point of the rod.
This ensures that the additional tube does not participate in the torsion of the hollow body part to be measured. The torsion angle is thus measured as the angle that is established between the tube, which does not participate in the torsion, and the rod.
The energy losses caused by the bearing are excluded from the measurement.
In the case of a torsion stressed, but resting pipe, this angle is easily read, in the case of a rotating shaft it appears as a rotation angle. B. an electronic angle meter used.
The torsion measurement can e.g. B. serve as a measure of the rotational forces acting on the pipe or for the forces acting in the opposite direction to the direction of rotation or their changes.
An embodiment of the invention is described in more detail below with reference to the drawing.
The drawing shows a cross section through a torsion measuring device which is arranged on a liquid container and is used here to measure the viscosity or change in viscosity of a liquid.
A hollow shaft 1 representing the hollow body serves to drive agitator blades immersed in the liquid. The hollow shaft with the insert tube 2, which is rigidly connected to the hollow shaft at 3, is driven by the motor 5 via a gear 4, is mounted at 6, carries agitator blades 7 at the other end, and is immersed in a stirred tank 9 filled with liquid 8 and is passed through the gland 10 through the lid of the container 9. The angle that is established between the insert tube 2 and the rod 11, which is rigidly attached to the free end of the hollow shaft, can serve as a measure of the viscosity of the liquid 8.
