Abstract
Description
Die Erfindung betrifft eine Wegmesseinrichtung für Maschinenteile mit rotierender und axialer Bewegungsrichtung gemäß Anspruch 1.The The invention relates to a displacement measuring device for machine parts with rotating and axial direction of movement according to claim 1.
Es gibt heute vielfältigste Gebersysteme für die Erfassung von Rotationsbewegungen. Das gleiche gilt für die Erfassung von Linearbewegungen. Diese Lineargeber sind heute so ausgebildet, dass der bewegte vom Geber zu messende Maschinenteil nur eine Linearbewegung ausführen darf und keine kombinierte Rotations- und Axialbewegung. Zur Messung einer kombinierten Rotations- und Axialbewegung sind zwei Gebersysteme erforderlich, wobei jeweils ein Gebersystem für die Erfassung der Rotationsbewegung und der Linearbewegung bzw. Axialbewegung benötigt wird.It Today gives the most diverse Encoder systems for the Detection of rotational movements. The same applies to the capture of linear movements. These linear encoders are designed today that the moving machine part to be measured by the encoder is only a linear movement To run allowed and no combined rotational and axial movement. For measurement A combined rotational and axial movement are two encoder systems required, each with a donor system for detecting the rotational movement and the linear movement or axial movement is needed.
Es ist die Aufgabe der vorliegenden Erfindung eine Wegmesseinrichtung für Maschinenteile mit rotierender und axialer Bewegungsrichtung zu schaffen, welche beide Bewegungen mittels nur eines Sensors ermittelt.It the object of the present invention is a displacement measuring device for machine parts with rotating and axial movement to create, both Movements determined by only one sensor.
Diese Aufgabe wird mit den Merkmalen des Anspruches 1 gelöst.These The object is achieved with the features of claim 1.
Bedeutungsvoll ist, dass durch Abtastung einer auf dem rotierenden und sich axial bewegenden Maschinenteil angeordneten Struktur, deren Ausdehnung und Lage im Sichtfeld des Sensors, Signalgebers oder Lesekopfes in Umfangsrichtung abhängig von der radialen und axialen Stellung des Maschinenteiles ist. Eine solche Struktur kann beispielsweise durch zwei winklig zueinander angeordnete Markierungen auf der Achse oder Welle des Maschinenteiles realisiert werden. Die Größe des Winkels α zwischen den beiden Markierungen bestimmt die Genauigkeit der Auflösung, d.h. bei einem größeren Winkel α wird die Genauigkeit der Messung bzw. Positionsermittlung erhöht. Vorteilhafterweise kann die Markierung, mittels derer die rotative Lage des Maschinenteiles ermittelbar ist, wie eine Sinus-Cosinus-Kurve ausgestaltet sein. Durch die beiden Markierungen kann die Position des Maschinenteiles eindeutig bestimmt werden, so dass keine Referenzfahrt bei einem Datenverlust des Standortes nötig ist. Zusätzlich können die Umdrehungen des Maschinenteiles gezählt werden, so dass die Messeinrichtung wie ein Absolutwertgeber, mittels dem gleichzeitig eine axiale und rotative Lage ermittelbar ist, fungiert.significant is that by scanning one on the rotating and moving axially moving machine part arranged structure, whose extension and position in the field of view of the sensor, signal transmitter or read head in the circumferential direction depends on the radial and axial position of the machine part is. A such structure can be, for example, by two angles to each other arranged markings on the axis or shaft of the machine part will be realized. The size of the angle α between the two marks determine the accuracy of the resolution, i. at a larger angle α is the Accuracy of the measurement or position determination increased. advantageously, can the marking, by means of which the rotary position of the machine part can be determined as a sine-cosine curve to be designed. By the two markings can the position of the machine part be clearly determined so that no homing at a Data loss of the location necessary is. additionally can the revolutions of the machine part are counted, so that the measuring device like an absolute encoder, by means of which an axial and rotative position is determined acts.
Die Struktur kann beispielsweise durch zwei zueinander beabstandet angeordnete Markierungen auf der Achse oder Welle des Maschinenteiles realisiert werden. Die Größe des Abstandes zwischen den beiden Markierungen bestimmt die Genauigkeit der Auflösung, d.h. bei einem größeren bzw. sich vergrößernden Abstand wird die Genauigkeit der Messung bzw. Positionsermittlung erhöht. Die Markierungen beschränken sich in ihrer Ausgestaltung nicht auf geradlinige Linien oder keilförmige Strukturen, sondern können aus Punkten, Keilen, Sin-Cosinus-Kurven oder Teilen einer Sin-Cosinus-Kurve bestehen.The Structure may, for example, by two spaced apart Markings realized on the axis or shaft of the machine part become. The size of the gap between the two marks determines the accuracy of the resolution, i. at a larger or expanding Distance is the accuracy of the measurement or position determination elevated. Restrict the markers in their design not on straight lines or wedge-shaped structures, but you can from points, wedges, sin cosines, or parts of a sin cosine curve consist.
