Fig. 3: Centrifugal disk on output side 1 Centrifugal disk 5.7.5 Oildam pipe By sealing the vertically downward pointing input shaft with contactfree and wearfree shaft seal ( socalled "oildam pipe") the shaft outlet is sealed absolutely tight to prevent oil escaping. This system is used only for forced lubrication. The lower antifriction bearing of the output shaft is separated from the gearunit interior by the oildam pipe and is lubricrated by grease. Grease is prevented from escaping by the use of radial shaft sealing ring. The relubrication interval
