Abstract

The gear box has parallel shafts comprising a multidisk clutch (7) and pinions (4) lubricated by an oil, and a clutch compartment (12). A mechanical compartment (11) contains the pinions and is separated from the clutch compartment by a partition (14). The clutch drives a primary shaft (1) traversing the partition. A double lip sealing device (25) is provided between the primary shaft and the partition to ensure a sealing in two directions between the lubrication oil of the pinions and the clutch oil.
