Description

Die Erfindung betrifft eine Abdichtung für Wellen mit selbsttätiger Anpressung gegen die abzudichtende Stelle, wobei die Dichtung untergebracht ist in einer auf der Welle sitzenden Dichtungsscheibe mit einer ringförmigen Nut. Erfindungsgemäß ist die Dichtung mehrfach unterteilt.The invention relates to a seal for shafts with automatic pressure against the point to be sealed, the seal being housed in one on the shaft seated sealing washer with an annular groove. According to the invention is the seal subdivided several times.

In der Zeichnung ist der Gegenstand schematisch dargestellt. Es zeigt:
ίο Abb. ι einen Querschnitt durch die Vorrichtung nach A-B, In the drawing, the object is shown schematically. It shows:
ίο Fig. ι a cross section through the device according to AB,

Abb. 2 einen Schnitt nach der Längsachse. Fig. 2 a section along the longitudinal axis.

Die Dichtung c ist durch Schnitte in tangentialer Richtung unterteilt. Ein oder mehrere Dichtungsteile sind versehen mit einem ebenfalls in tangentialer Richtung verlaufendem Langloch d, in welches ein an der Dichtungsscheibe α sitzender Stift e mit geringem Spiel eingreift.The seal c is divided by cuts in the tangential direction. One or more sealing parts are provided with an elongated hole d, likewise running in the tangential direction, into which a pin e seated on the sealing washer α engages with little play.

Beim Umlaufen der auf der Welle sitzenden Dichtungsscheibe α wird die gesamte Dichtung c durch den Stift e in Umdrehung versetzt. Die Pressung an der abzudichtenden Wand durch die Zentrifugalkraft wird durch den Anzug des im Langloch d auflaufenden Stiftes e vermehrt. Der Abdichtungsdruck pflanzt sich infolge der beson- · deren Schnittführung der unterteilten Dichtung c über alle Teüstücke gleichmäßig fort je nach der Umdrehungszahl der Welle mit entsprechender Stärke.When the sealing washer α on the shaft rotates, the entire seal c is set in rotation by the pin e. The pressure on the wall to be sealed by the centrifugal force is increased by the tightening of the pin e running up in the elongated hole d . As a result of the special cut of the subdivided seal c , the sealing pressure is propagated evenly over all parts, depending on the number of revolutions of the shaft, with a corresponding strength.
