Description
WinkelgeberAngle encoder
Die Erfindung betrifft einen Winkelgeber gemäß den Merkmalen des Oberbegriffes des Anspruches 1.The invention relates to an angle encoder according to the features of the preamble of claim 1.
Mit Hilfe derartiger Geber werden Maschinen, z.B.With the help of such encoders, machines, e.g.
Pressen, Walzstraßen usf., in Abhängigkeit von einer bestimmten Arbeitsstellung (Winkel) gesteuert.Presses, rolling mills, etc., depending on a specific work position (Angle) controlled.
Die Ertastung des Winkels geschieht auf physikalischem Wege, etwa optisch, magnetisch oder durch Hallgeber.The angle is sensed physically, for example optically, magnetically or by means of a Hall sensor.
Die Tachowelle rotiert dabei mit der gleichen Winkelgeschwindigkeit wie die Maschine. Die erhaltenen optischen, magnetischen, bzw. elektrischen Impulse werden einer Elektronik zur Weiterverarbeitung zugeleitet.The speedometer shaft rotates at the same angular speed like the machine. The received optical, magnetic or electrical impulses are sent to electronics for further processing.
Die Lagerung der Tachowelle von bekannten, auf dem Markt sich befindlichen Winkelgebern ist über zwei einreihige Radialkugellager vorgenommen. Deren voneinander getrennten-äußeren Lagerschalen sind über ein Paßstück verbunden. Die inneren Lagerschalen sind auf der Tachowelle aufgeklebt. Bei dieser aufwendigen Konstruktion addieren sich Fertigungsfehler, was störanfällige Winkelgeber mit unrundem Lauf der Tachowelle zur Folge hat. Man muß daher dazu übergehen die Lager vorzusortieren, was lohnintensiver ist und zu hohen Ausschußquoten führt.The storage of the speedometer cable from known ones on the market Angle encoder is made using two single-row radial ball bearings. Theirs from each other separate outer bearing shells are connected via a fitting. The inner bearing shells are glued to the speedometer cable. Add up in this complex construction manufacturing errors, which can cause fault-prone angle encoders with an out-of-round running of the speedometer cable has the consequence. One must therefore go over to pre-sorting the stocks, which is more wage-intensive and leads to high reject rates.
Die Aufgabe der Erfindung besteht darin, einen auch bei hohen Drehzahlen präzise arbeitenden, ruhig laufenden, einfach und genau zu montierenden Winkelgeber zu schaffen, der sich besonders kostengünstig fertigen läßt, Diese Aufgabe wird mit den kennzeichnenden Merkmalen des Anspruches 1 gelöst.The object of the invention is to provide one even at high speeds Precisely working, smoothly running, easy and precisely to assemble angle encoder to create that can be manufactured particularly inexpensively, this task is solved with the characterizing features of claim 1.
Das Lager des neuen Winkelgebers läßt sich wie ein einziges doppelreihiges Lager maschinell mit hoher Präzision fertigen. Innerhalb des Lagers sind keine Klebestellen mehr notwendig, die die Fertigungsgenauigkeit beeinträchtigen könnten. Eine Vorsortierung der Lager kann entfallen.The bearing of the new angle encoder can be folded like a single double row Machining bearings with high precision. There are no glue points inside the warehouse more necessary, which could affect the manufacturing accuracy. A pre-sorting the warehouse can be omitted.
Die Montage des Winkelgebers wird mit hoher Genauigkeit dann gelingen, wenn dessen Anbauteile, wie Flansche, auf der äußeren gemeinsamen Lagerschale montiert werden, auf der sie sich einfach fixieren lassen.The angle encoder can then be installed with a high degree of accuracy if its add-on parts, such as flanges, are mounted on the outer common bearing shell on which they can easily be fixed.
Mit Vorteil kann das eine Ende der äußeren Lager schale als Zentrieransatz beim Anbau des Winkelgebers dienen.One end of the outer bearing can advantageously be used as a centering shoulder when mounting the angle encoder.
Dadurch wird eine besondere Lagejustierung des Winkelgebers entbehrlich.As a result, a special position adjustment of the angle encoder is unnecessary.
Weitere vorteilhafte Ausgestaltungsmerkmale der Erfindung sind den Unteransprüchen zu entnehmen.Further advantageous design features of the invention are the Refer to subclaims.
Die Figur zeigt einen Schnitt durch einen Winkelgeber in beispielhafter Ausführungsform.The figure shows a section through an angle encoder in an exemplary manner Embodiment.
Mit 1 ist die Tachowelle des Winkelgebers bezeichnet.1 with the speedometer cable of the angle encoder is referred to.
Sie ist in einer gemeinsamen äußeren festen Lagerschale 2 geführt, in der sie sich über zwei Kugellagerstellen abrollt. Die innere Lagerschale bildet die Tachowelle selbst, die umfänglich Ausnehmungen 3 für die Kugeln 4 des Lagers enthält.It is guided in a common outer fixed bearing shell 2, in which it rolls over two ball bearing points. The inner bearing shell forms the speedometer cable itself, the circumferential recesses 3 for the balls 4 of the bearing contains.
In eine Nut am Umfang der Lagerschale 2 greift ein Sprengring 5 ein, der als Anschlag für den fest mit der Lagerschale 2 verbundenen Flansch 6 dient. Die Lagerschale steht gegenüber der Montagefläche des Flansches 6 etwas hervor und bildet somit einen für eine paßgenaue Montage wichtigen Zentrieransatz 7.A snap ring 5 engages in a groove on the circumference of the bearing shell 2, which serves as a stop for the flange 6 firmly connected to the bearing shell 2. The bearing shell protrudes slightly from the mounting surface of the flange 6 and thus forms a centering shoulder 7 that is important for a precisely fitting assembly.
Ein stirnseitiger Dichtring 8 zwischen Lager schale 2 und Tachowelle 1 schützt die Kugellager gegen das Eindringen von Staub und Fremdkörpern.An end sealing ring 8 between the bearing shell 2 and the speedometer cable 1 protects the ball bearings against the ingress of dust and foreign bodies.
Die gegenüberliegende Seite der Tachowelle 1 ist mit einem Anlagering 9 abgeschlossen, der gleichzeitig eine mit der Winkelgeschwindigkeit der Tachowelle rotierende, mit Markierungen versehene lichtdurchlässige Scheibe 10 trägt.The opposite side of the speedometer cable 1 has an attachment ring 9 completed, the one at the same time with the angular speed of the speedometer cable rotating, marked translucent disk 10 carries.
Die Scheibe 10 rotiert vor einem stationären Abtastelement 11, das mittels eines Halters 11a an der Lagerschale 2 festgemacht ist. Für den Halter 11a ist der Sprengring ein Anschlagpunkt für die Montage.The disk 10 rotates in front of a stationary scanning element 11, the is fixed to the bearing shell 2 by means of a holder 11a. For the holder 11a the snap ring is an attachment point for assembly.
Die der Montagefläche des Flansches 6 abgewandte Seite des Winkelgebers ist von einer zylindrischen Isolierstoffkappe 12 umschlossen. Diese wird auf einen Absatz 13 des Flansches 6 passend aufgeschoben.The side of the angle encoder facing away from the mounting surface of the flange 6 is enclosed by a cylindrical insulating material cap 12. This will be on a Paragraph 13 of the flange 6 pushed on to match.
Dabei gleitet für eine elastische Rastverbindung ein nach innen ragender Wulst 14 der Isolierstoffkappe in eine entsprechende, umlaufende Nut 15 am Absatz 13.An inwardly protruding one slides for an elastic locking connection Bead 14 of the insulating cap in a corresponding, circumferential groove 15 on the shoulder 13th
Diese Verbindung ist nicht mehr ohne weiteres zu öffnen, da sich die Isolierstoffkappe mit der Stirn gegen die vorspringende Fläche 16 des Flansches 6 legt und einer elastischen Aufweitung nicht mehr zugänglich ist.This connection can no longer be opened easily because the Isolierstoffkappe with the forehead against the projecting surface 16 of the flange 6 places and an elastic expansion is no longer accessible.
Ein feststehender am Halter 11a festgemachter Träger 17 beherbergt Bauelemente der elektronischen Einrichtung, insbesondere einen Sender bzw. Empfänger, für die Lichtsignalübertragung an der dem stationären Abtastelement 11 gegenüberliegenden Stelle.A fixed bracket 17 fixed to the holder 11a houses Components of the electronic device, in particular a transmitter or receiver, for the light signal transmission on the one opposite the stationary scanning element 11 Job.
Auf einer Platte 18 innerhalb der Isolierstoffkappe sind weitere elektronische Bauelemente unterbringbar, deren Leitungsanschlüsse über den Verschraubungsdurchbruch 19 nach außen führbar sind.On a plate 18 within the insulating cap are further electronic Components can be accommodated, their line connections via the screw opening 19 can be guided to the outside.
