Abstract
Description
Die Erfindung betrifft eine Anordnung zur Beseitigung des Spiels einer Gewindepaarung, bevorzugt zur Positionierung in einer zylinderförmigen Fassung gefasster rotationssymmetrischer optischer Elemente in einer Aufnahme, wie beispielsweise eines Objektives in einem Chassis eines Projektors, umfassend die mit einem Außengewinde versehene Fassung, welche in der das Gegengewinde aufweisenden Aufnahme eingeschraubt ist.The The invention relates to an arrangement for eliminating the game of a Thread pairing, preferably for positioning in a cylindrical socket shaped rotationally symmetrical optical elements in a receptacle, such as an objective in a chassis of a projector with an external thread provided socket, which in the counter thread having recording is screwed.
Gewindepaarungen besitzen fertigungsbedingt üblicherweise ein radiales Spiel zwischen den Flanken der miteinander verschraubten Elemente. Um dieses Spiel, insbesondere bei Gewindepaarungen, bei dehnen gefasste optische Elemente hochgenau in entsprechenden Aufnahmen positioniert werden müssen, zu beseitigen, wird bekannterweise zwischen die zu paarenden Flanken Klebeband eingelegt. Dies erfordert mitunter ein mehrmaliges Ein- und Ausschrauben des zu fixierenden Elementes in Verbindung mit dem Neueinlegen von Klebeband.thread pairings are customary for manufacturing reasons a radial clearance between the flanks of the bolted together Elements. To this game, especially in thread pairings, at stretch captured optical elements with high precision in corresponding recordings need to be positioned it is well known to eliminate between the mating flanks Adhesive tape inserted. This sometimes requires a multiple and unscrewing the element to be fixed in conjunction with reinstalling tape.
In
Den bekannten Gewindepaarungen haftet der Nachteil an, dass der anordnungstechnische Aufwand zur Beseitigung des Spiels der gepaarten Gewindeflanken sehr groß ist.The Known thread pairings has the disadvantage that the arrangement technical Effort to eliminate the game of paired thread flanks is very big.
Davon ausgehend liegt der Erfindung die Aufgabe zugrunde, eine Anordnung zur Beseitigung des Spiels einer Gewindepaarung dahingehend weiter zu entwickeln, dass mittels einfacher Mittel der anordnungstechnische Aufwand reduziert wird.From that Based on the object of the invention, an arrangement to eliminate the game of a thread mating to that effect to develop that by means of simple means of arrangement technical Effort is reduced.
Erfindungsgemäß wird die Aufgabe durch eine Anordnung der eingangs beschriebenen Art dadurch gelöst, dass im Bereich des Aussengwindes der Fassung und/oder des Innengewinde des Chassis, mindestens zwei zueinander versetzt angeordnete gewindelose Stege angeformt sind, wobei zweckmäßigerweise drei um 120 Grad zueinander versetzt angeordnete Stege vorgesehen sind und die Stege entgegen der Einschraubdrehrichtung eine keilförmig zunehmende Form aufweisen.According to the invention Task by an arrangement of the type described above characterized solved, that in the area of the outside air of the socket and / or the internal thread of the chassis, at least two offset from each other threadless Webs are formed, with expediently three by 120 degrees webs offset from one another are provided and the webs are opposite the Einschraubdrehrichtung have a wedge-shaped increasing shape.
Beim Einschrauben der gefassten optischen Elemente in die Aufnahme kommt es über das Innengewinde der Aufnahme zur Einarbeitung von Gewinderillen in die verformbaren Stege der Fassung. Dadurch wird das Gewindespiel zwischen Aufnahme und Fassung vollständig beseitigt, ohne dass dabei die Leichtgängigkeit beim Ein- oder Ausschrauben der Fassung in die Aufnahme verloren geht.At the Screwing the captured optical elements into the receptacle comes it over the internal thread of the receptacle for the incorporation of thread grooves in the deformable webs of the socket. This will be the thread play between recording and version completely eliminated, without doing the ease when screwing in or unscrewing the socket lost in the recording goes.
Vorteilhafterweise sollte die Länge des Steges 1,1 mm und die maximale Höhe des Steges 0,29 mm sein.advantageously, should be the length of the bridge 1.1 mm and the maximum height of the bridge be 0.29 mm.
Anhand eines Ausführungsbeispiels wird nachfolgend die erfindungsgemäße Anordnung naher erläutert. Dabei zeigen:Based an embodiment the arrangement according to the invention will be explained in more detail below. there demonstrate:
