A thrust bearing of the Michell type is arranged in such a manner around an associated journal bearing (21; 39) that one set of the thrust segments (25, 25', 25'') is positioned on one side of the bearing while the other set of thrust segments (29; 29'') is positioned on the other side of the bearing. The axial length of the bearing is short because it has only one journal bearing. The length of the thrust bearing may be further shortened in that the set of thrust segments (29; 29'') transferring the axial thrust while going aster has a smaller axial thickness than the second set of thrust segments. The thrust bearing may be arranged around the aft main bearing (21) in the piston engine, and in that case the forward set of thrust segments (29) may slide against the rear side (30) of the aft crank arm (3). The upper part (22, 23') of the bearing may be designed as a segment stopper preventing the segments from rotating in the rotational direction of the shaft and the segments may abut directly on an axially directed surface of the stationary structure of the journal bearing. |
