Abstract
A slide ring seal assembly for installation on a shaft includes an axially displaceable slide ring; an elastic collar arranged coaxially with the slide ring and being in engagement with the slide ring for providing a static seal between the slide ring and the shaft, and a helical compression spring having opposite first and second ends. The compression spring is arranged coaxially with the slide ring and the elastic collar and exerts a radial force on the shaft with at least one first spring turn. The second end is situated at the slide ring and is operatively connected therewith for axially urging the slide ring towards a counterring in the installed state of the assembly. At the second spring end at least one second turn surrounds the slide ring with a radial bias and further, the compression spring axially presses, with at least one third turn, the free end face of the slide ring with the intermediary of the elastic collar. Further, the compression spring, with at least one fourth turn in the zone of the static seal between the slide ring and the shaft, lies on the outer circumference on the elastic collar and presses the latter radially against the shaft.
