Description

Axial geteilter Einsatz für Stopfbüchsen Die bekannten Stopfbüchsen mit Metallpackungsringen, wie sie hauptsächlich für Kolbenstangen der Lokomotiven Verwendung finden, bestehen aus einem zweiteiligen Einsatz und den Dichtungselementen.Axially split insert for stuffing boxes The well-known stuffing boxes with metal packing rings, such as those used mainly for piston rods in locomotives Find use, consist of a two-part insert and the sealing elements.

Die Dichtung des Einsatzes erfolgt in den Teilfugen durch Schraubenverbindungen, im übrigen wird er gegen den Zylinderdeckel mittels Packung abgedichtet. Da sich wegen Raummangels die erforderlichen Schraubenstärken für das Zusammenziehen der beiden Einsatzhälften nicht verwenden- lassen, bietet das Dichten in der Längsfuge oft Schwierigkeiten.The insert is sealed in the butt joints by screw connections, otherwise it is sealed against the cylinder cover by means of a packing. That I due to lack of space the necessary screw strengths for the contraction of the Do not allow both halves of the insert to be used, sealing in the longitudinal joint provides often difficulties.

Die vorliegende Erfindung besteht darin, die Dichtung des Einsatzes in der Teilfuge in einfacher Weise durch Verwendung von Baustoffen mit verschiedenen Ausdelinungskoeffizienten zu erreichen.The present invention is the seal of the insert in the parting line in a simple manner by using building materials with different To achieve the coefficient of deformation.

In das Gehäuse a aus Gußeisen oder Stahlguß wird der geteilte Einsatz b aus Bronze eingesetzt. Die Passung des Einsatzes in seinem äußeren Durchmesser wird so gewählt, daß bei Erwärmung durch die größere Dehnung eine Pressung auftritt, wodurch die Abdichtung des Einsatzes in der Teilfuge und am Umfang erfolgt.The split insert is placed in the housing a made of cast iron or cast steel b made of bronze. The fit of the insert in its outer diameter is chosen in such a way that when the temperature is increased, a compression occurs due to the greater elongation, whereby the sealing of the insert takes place in the parting line and on the circumference.

Claims (1)

PATENTANSPRUCH: Axial geteilter, aus anderem Material als das Gehäuse bestehendem Einsatz für Stopfbüchsen, dadurch gekennzeichnet, daß der Einsatz (b) außen eine glatte zylindrische Mantelfläche besitzt und mit nur geringem Spiel lose in das Gehäuse (a) eingesetzt ist, so daß durch die bei höherer Temperatur eintretende Dehnung des Einsatzes die Dichtung in seinen Teilfugen und zwischen seinem äußeren Umfange und dem Gehäuse bewirkt wird. PATENT CLAIM: Axially split, made of a different material than the housing existing insert for stuffing boxes, characterized in that the insert (b) has a smooth cylindrical outer surface and is loosely inserted into the housing (a) with little play, so that the at higher temperatures occurring expansion of the insert the seal in its butt joints and between its outer circumference and the housing is effected.
