FREE JET CENTRIFUGE

摘要

The invention relates to a free jet centrifuge, especially for cleaning the lubricating oil of an internal combustion engine. The aim of the invention is to provide a centrifuge which is economical to produce and at the same time allows for high speeds. To this end the invention on one side of the rotor provides for a ball bearing (16) in the housing, which engages a closed shaft journal (14) of the rotor. In the area of this bearing the rotor is sealed so that the friction in the ball bearing is not raised by the oil pressure in the centrifuge. A slide bearing is provided for on the other side of the rotor which consists of a bearing bushing (20) and a sliding bush (21). In this way a combination of materials which is optimal in terms of tribological properties can be selected. A hollow journal (19) which also acts as oil inlet (24) for the centrifuge rotor is inserted into the sliding bush. To increase speed even further the invention provides for a pulse channel (30) which discharges into nozzles (31). This device is integrated into a plastic base of the rotor (13) which permits the production of highly precise input nozzles (31).
