Sealing system for a drive unit consisting of a motor and a transmission

A sealing system for fast-running motors with a directly flanged-on gear unit, used for passenger conveyor systems such as escalators and moving walkways, said sealing system including:

• at least one sealing element comprising a radial shaft seal;
• at least one centrifugal element;
• at least one cover and suctioning element, the cover and suctioning element having a disk-shaped design with an outer peripheral surface tapered in the direction of the sealing element;
• and
• a lubricating oil collection chamber, provided in a region of the centrifugal element and connected via at least one channel that extends in the direction of the cover and suctioning element to a gear unit chamber of the gear unit, the gear unit chamber being located above an oil level in an intake region of the cover and suctioning element,
• wherein the cover and suctioning element is arranged between the gear unit and the sealing element, and
• the oil level in the gear unit chamber is designed to reach below the cover and suctioning element in the fully mounted condition.

• and
• a transport safety device that blocks the at least one channel against the lubricating oil collection chamber for transport and mounting purposes and which can be removed once the passenger conveyor system is fully installed,
• wherein the cover and suctioning element is arranged between the gear unit and the sealing element.
