The invention relates to a screw-type centrifuge configured in such a way that the use of multistage planetary gear trains allows for high peripheral speeds of the drum and large drum diameters. According to the invention the drum bearing (5) on the gear train side is positioned between two stages (7, 8) of the multistage planetary gear train. The housing jacket (10) of the multistage planetary gear train, which is connected to the drum jacket (11) and therefore rotates at the same r.p.m., has an intermediate piece (12) which has a small diameter and is housed by the drum bearing (5) together with a shaft (13) connecting the gear train stages (7 and 8). The system provided for in the invention, according to which the drum bearing (5) on the gear train side is positioned between two stages of the multistage planetary gear train, is used in the case of very large decanters for which the drum rotates at very high peripheral speeds.
