Abstract
A mechanical seal, independent of the direction of rotation, for a shaft duct having a sliding ring (2) rotating with the shaft, an opposing ring (3), fixed to the housing, a driver ring (4) and a spring arrangement (5) between the driver ring (4) and the sliding ring (2). The driver ring (4) can be fixed on the shaft (1). The spring arrangement (5) presses the mechanical seal (2) against the opposing ring (3) with a lubricant film between them. The spring arrangement (5) has positively locking elements (8) which interact in a driving manner with positively locking opposing elements (9) on the opposing ring (3) and on the mechanical seal (2). The spring arrangement (5) consists of at least one sprung corrugated ring with corrugation peaks (10) and corrugation troughs (11), which surrounds the shaft (1) and has positively locking elements (8) which project from the ring surface and are distributed evenly around the circumference. These positively locking elements (8) engage in positively locking recesses (9) on the opposing ring (3) and on the mechanical seal (2). <IMAGE>
