5.1.3 Thrust bearing
The thrust bearing is installed on the crankshaft at the driving end of the engine. The thrust
bearing flange (014, Figure 5-3) transmits the axial thrust from the propeller through the thrust
pads into the bedplate:
•
The thrust pads on the engine side adapt the propeller thrust of the ahead direction.
•
The thrust pads on the driving end adapt the propeller thrust of the astern direction.
The thrust pads adapt to the clockwise or counterclockwise rotation of the engine.
The arbor supports (004) prevent circular movement of the thrust pads.
Bearing oil flows through the oil pipe (002) to the two nozzles (003). The oil flows out of the two
nozzles as a spray, which becomes an oil layer between the thrust bearing flange (014) and the
thrust pads (006, 013).
