<p>An arrangement for the sealing of a shaft which passes through a plate , which separates the "wet" and the "dry" zone of a packing machine from each other . In packing machines great demands are made on the tightness and durability of such shaft bushings, especially against strong washing agents, and the sealing assembly in accordance with the invention, therefore, has a flexible connection with the plate and two O-rings , which are partly enclosed by the two halves of the sealing assembly and thereby are protected during washing as well as during operation. This design also produces a good sealing effect when during operation the shaft moves a little in radial direction.</p> |
