Description
< S P A N N A B E ) __ _<S P A N N A B E) __ _
Die Neuerung betrifft eine auf einer Welle verspannbare Nabe mit einer Innenbüchse, deren Innenfläche mit der Welle reibschlüssig verspannbar ist, und einer die Innenbüchse umgebenden Außenbüchse, wobei die Außenfläche der Innenbüchse und die Innenfläche der Außenbüchse je einen korrespondierenden konischen Abschnitt aufweisen, welche durch axiales Festziehen der Innen- und Außenbüchse mittels über den Umfang verteilter achsparalleler Zugbolzen verspannbar sind.The innovation relates to a hub that can be clamped on a shaft and has an inner sleeve, the inner surface of which is frictionally engaged with the shaft is clamped, and an outer sleeve surrounding the inner sleeve, the outer surface of the inner sleeve and the inner surface of the outer sleeve each have a corresponding one have conical section, which by axially tightening the inner and outer sleeve by means of the circumference distributed axially parallel tension bolts can be tightened.
Unter der Vielzahl der Spannaben sind jene von Bedeutung, die aus einem außen gestuft kegeligen oder doppelkegeligen Innenteil und einem innen kegeligen Außenteil bestehen und mittels Spannschrauben axial zusammengezogen und somit radial zwischen Nab^ und Welle verspannt werden, wodurch eine Kraftübertragung löglich ist.Among the large number of clamping hubs, those of importance are those consisting of an externally stepped conical or double-conical The inner part and an internally tapered outer part exist and are axially drawn together by means of clamping screws and thus radially between the hub ^ and the shaft are tensioned, whereby a power transmission is possible.

Neuerungsgemäß wurde eine vereinfachte Spannabe entwickelt, bei der gemäß der Zeichnung das Innenteil (1) nur einen Aussenkegel und ö»e Aujsenteii (2) nur einen Innenkegel besitzt« wobei wahlweise das Innenteil oder auch das Außenteil im Achsschnitt geschlitzt sein kann (4). Zur axialen Verspannung dienen wahlweise Innensechskant-(3) oder normale Sechskantschrauben, die au' einem Teilkreis verteilt so angeordnet sind, daß die Durchgangslöcher für die Schrauben durch die Kegelflachen dringen, wodurch die Gewindelöcher für die Aufnahme der Schrauben außerhalb der sich berührenden Kegelflächen wahlweise im Innen- oder im Außenteil sind.According to the innovation, a simplified clamping hub was developed, in which, according to the drawing, the inner part (1) has only one outer cone and the outer part (2) has only one inner cone " whereby either the inner part or the outer part can be slotted in the axial section (4). For axial bracing, either hexagon socket (3) or normal hexagon screws, which are on a pitch circle, are used distributed so that the through holes for the screws penetrate through the conical surfaces, whereby the Threaded holes for receiving the screws outside the conical surfaces in contact, either in the inside or in the Outer part are.
Diese Ausführung hat den Vorteil, daß die Durchgangslöcher und die Gewindelöcher bei der Fertigung im zusammengesteckten Zustand problemlos gebohrt werden können.This design has the advantage that the through holes and the threaded holes can be easily drilled in the assembled state during manufacture.
Nachdem bei dieser Konstruktion der Kegel relativ steil ist und nur noch zur Sicherheit eine axiale Abdrückmöglichkeit bestehen muß, sind zwischen den Schraubenlöchern entsprechende Gewindelöcher zur Aufnahme von Abdrückschrauben vorhanden.Since the cone is relatively steep in this construction and only for safety an axial push-off option must exist, there are corresponding threaded holes between the screw holes to accommodate forcing screws available.
Damit als Abdrückschrauben die herausgeschraubten Anzugschrauben verwendet werden können, ist es notwendig, daß diese Gewindelöcher auf der Rückseite (5) als Schraubendurchgangs löcher aufgebohrt werden. Als Gegenlager zum Abstützen der Abdrückschrauben dienen Gewindestopfen (6), die in entsprechenden Gewinden von der Rückseite eingeschraubt und gegen Verdrehung gesichert werden.So that the unscrewed tightening screws can be used as jacking screws, it is necessary that these The threaded holes on the back (5) can be drilled out as screw through holes. As a counter bearing to support the Forcing screws are used for threaded plugs (6) that are inserted into the corresponding Threads screwed in from the rear and secured against rotation.
