ABSTRACT:
An assembly for the leakage-free removal of bearing oil from sliding bearings for rotating shafts of high-speed machines, includes a sliding bearing axially divided into bearing cups, contactless shaft seals near bearing end surface preventing escape to the surroundings of bearing oil fed to surfaces of the sliding bearing, an annular oil collecting canal disposed at least at one side of the sliding bearing between a shaft seal and a bearing end surface having an outer peripheral wall with an arcuate cutout formed therein with a slot-shaped opening arc defining an outlet opening through which the collecting canal discharges an oil flow, the opening arc covering a circumferential angular range of the shaft extending at least from the geodetically lowest point of the outer contour of the collecting canal at most to a position of the outer contour defined by the parting line of the cups as seen in shaft rotation direction, an oil collecting box with an oil flow space and an inlet opening matched to the outlet cross section of the opening arc and sealed to the opening arc for receiving oil from the outlet opening, tangentially arched baffles dividing the oil flow space into a plurality of oil flow channels for dividing an oil spray fan downwardly thrown off from the lower surface of the shaft and downwardly deflecting oil sprays thereof, and a common downwardly directed transition piece receiving the oil flow from the oil flow channels.
