Abstract

The frictional hub-to-shaft connection comprises two conical first rings (5) seated on the thin-walled hub with their small diameter ends adjacent one another. Seated on the conical rings are second rings (3) whose confronting sides have tapered recesses such that when slide blocks (4) contained in the recesses are drawn radially outwards by Jack screws (7), the second rings are urged apart axially and the first rings are compressed radially which compresses the hub to grip the shaft. The first rings are located on the hub against movement away from one another and, like the hub, the first rings are relatively thin-walled.

Description

Spannscheiben für Welle/Nabe-Verbindung Die Erfindung betrifft aine reibschlüssige lösbare Welle/Nabe-Verbindung für den Maschinenbau.Spring washers for shaft / hub connection The invention relates to aine Frictionally engaged, detachable shaft / hub connection for mechanical engineering.

FUr die Verbindung einer Welle mit einer Nabe oder von zwei Wellen über eine Hülse werden durch das Verbindungselement axiale und tangentiale Kräfte sowie Drehmomente und Biegemomente übertragen.For connecting a shaft with a hub or two shafts Axial and tangential forces are generated by the connecting element via a sleeve as well as transferring torques and bending moments.

Es ist bekannt diese Verbindung silber Ringe mit konischer Außen- und zylindrischer Innenfläche durch einmalige Umlenkung von Kräften, welche über axial angeordnete Spannschrauben erzeugt werden, herzustellen (Zeitschrift Schrift und Hafen, Heft 9, Soft. 1972).It is known this compound silver rings with conical outer and cylindrical inner surface by one-time deflection of forces which exceed axially arranged clamping screws are generated (magazine Schrift and Hafen, Issue 9, Soft. 1972).

Weithin ist bekannt, die Verbindung über ein hydraulischen Druck in einer Hohlscheibe mit dünner innerer Radialwandung und massiven Außen- und Kopfseiten herzustellen.It is widely known that the connection via a hydraulic pressure in a hollow disk with a thin inner radial wall and solid outer and head sides to manufacture.

Auch ist es bekannt dünne Ringe mit konischer Außen- und zylindrischer Innenfläche zwischen einer konischen Hohlbohrung und einer Welle zu spannen.It is also known thin rings with conical outer and cylindrical Clamp the inner surface between a conical hollow bore and a shaft.

Bei den bekannten Verbindungen sind zum Teil die erreichbaren Flächenpressungen und damit die Reibkräfte zu gering, oder aber es werden zur Erzeugung der erforderlichen Spannkräfte eine Vielzahl von Spannschrauben benötigt.The surface pressures that can be achieved are some of the known connections and thus the frictional forces are too low, or it will be necessary to generate the necessary Clamping forces a large number of clamping screws are required.

Der Erfindung liegt der Gedanke zugrunde eine Konstruktiono-Vereinfachung bei der Verbindung von wer Wellen zu erzielen, sowie an einer Verbindung bei größtmöglich Ubertragbaren Spannkräften eine möglichst geringe Zahl von Spannschrauben zu verwenden, bei gleichmäßiger Flächenpressug in der Verbindung.The invention is based on the idea of a construction simplification in connecting who to make waves, as well as on a connection with the greatest possible transferable clamping forces the smallest possible number of clamping screws to be used with even surface pressure in the connection.

Diese rufgabe wird erfindungsgemäß dadurch gelöst, daß der Spannsitz in bekannter Art durch zwei aufgeschobene dünnwandige Druckringe zusammengedrückt wird. Die Druckringe haben einen konischen Außenmantel auf der in bekannter Weise zwei Spannscheiben axial entgegengesetzt verschiebbar sind. Diese Verschiebung wird erreicht, indem radial gerichtet angeordnete Spannschrauben Uber mit konischen Seiten ausgebildeten Kulissensteinen auf den konisch ausgebildeten Stirnflächen der Spannscheiben radial nach außen bewegt werden. Die Spannkraft der Schraube wird somit zweimal umgelenkt und erhöht somit die Reibkraft im Verhältnis der Neigung des zweiten Konus.This task is achieved according to the invention in that the clamping seat pressed together in a known way by two pushed-on thin-walled pressure rings will. The pressure rings have a conical outer jacket in a known manner two conical spring washers are axially displaceable in opposite directions. This shift will achieved by radially arranged clamping screws Uber with conical sides trained sliding blocks on the conically shaped end faces of the clamping disks be moved radially outward. The clamping force of the screw is thus twice deflected and thus increases the frictional force in relation to the inclination of the second cone.

Außerdem wird insbesondere bei der Verbindung von zwei Wellen der Aufbau der Konstruktion gegenüber dem Bekannten wesentlich vereinfacht.In addition, especially when connecting two shafts, the Structure of the construction significantly simplified compared to the known.

AusfUhrungsbeispiele der Erfindung sind in den Zeichnungen Figur 1 und Figur 2 dargestellt und werden im folgenden näher beschribeben.Exemplary embodiments of the invention are shown in the drawings in FIG and FIG. 2 and are described in more detail below.

Figur 1: Es werden schematisch zwei Wellen reibschlüssig und leicht lösbar verbunden. Die Wellenenden (2) werden von einem dtinnwendigen, rohrförmigen, ungeteilten Ring ( 1) umschlossen, der durch zwei dünnwandige Druckringe (5) an die eingesteckten Wellen gepreßt wird. Über die Druckringe (5) sind in bekannter Art Spannscheiben (3) geschoben, welche auf entgegengesetzten Konen (3, B') axial entgegengesetzt verschiebbar sind. Die Verschiebung wird bewirkt, indem radial gerichtete gleichmaßig am Umfang verteilte Spannschrauben (oder hydraulisch betätigte Zugbolzen) (7) Kulissensteine (4) über die Konen (A, A') radial nach außen bewegen. Durch die zweimalige Umlenkung der Spannkraft wird eine nahezu gleichmäßige Verteilung der Pressung zwischen den Wellen (2) un der Hülse (1) erreicht. Beim Anziehen der Spannschraube werden die Druckringe (5) durch den Absatz der Hülse (1) und den Justierring (8) mit kleinen Schrauben (9) solange gegen die zunächst geringe axiale Verschiebekraft gesichert, bis sie radial an der Hülse anliegen und die radiale Haltekraft die axiale Verschiebekraft übersteigt. Bei weiterem Anziehen der Spann-Schrauben wird durch die wesentlich größere Haltekraft ein axiales Verschieben der Ringe (5) verhindert. Ein dünnwandiger Ring (6) dient als Auflager für die Spannschrauben. Die Reibverluste an den 3ewegungsteilen werden durch Petten mit entaprechendem Schmiermitteln stark herabgesetzt.Figure 1: Two shafts are schematically frictionally engaged and light releasably connected. The shaft ends (2) are held by an internal, tubular, undivided ring (1) enclosed by two thin-walled pressure rings (5) the inserted shafts is pressed. About the pressure rings (5) are known in Type conical spring washers (3) pushed, which axially on opposite cones (3, B ') are oppositely displaceable. The shift is effected by being radially directed Tensioning screws evenly distributed around the circumference (or hydraulically operated tension bolts) (7) Move the sliding blocks (4) radially outwards over the cones (A, A '). Through the double deflection of the clamping force results in an almost even distribution the Pressure between the shafts (2) and the sleeve (1) reached. When tightening the clamping screw the pressure rings (5) through the shoulder of the sleeve (1) and the adjusting ring (8) with small screws (9) against the initially low axial displacement force secured until they rest radially on the sleeve and the radial holding force the axial Displacement force exceeds. If the tensioning screws are tightened further, the the much greater holding force prevents the rings (5) from moving axially. A thin-walled ring (6) serves as a support for the tensioning screws. The friction losses on the moving parts are made strong by petting with corresponding lubricants degraded.

Für den Spannscheibensitz wird die Nabe als dünnwandiger ungeteilter zylindrischer Ring ausgebildet. Er wird durch die Druckringe (5) auf die Welle (2) gepreßt. Die auf den Konen (B, B') der Druckringe (5) verschieblichen Spannscheiben (3) werden bewegt, in dem radial gleichmäßig verteilte Spannschrauben (oder Zugbolzen) (7) Klilissensteine (4) über Klonen (A, A') radial nach außen ziehen. Die Justierscheibe (8) mit Schraube (9) dient zur Sicherung gegen axiales Verschieben der Druckringe (5) bei Beginn des Spannvorganges. Der dünnwandige Ring (6) dient als Auflager für die Schrauben.Piuur 2s It shows schematically the use of the connection for command a gear (1) on a shaft (2). The hub is used for the clamping disc seat designed as a thin-walled, undivided cylindrical ring. He is through the pressure rings (5) pressed onto the shaft (2).
