Crosshead Lubrication and Piston Cooling
1. General
Lubricating oil keeps the pistons cool. High pressure bearing oil lubricates the
crosshead. Each oil system operates independently. The oil from each system flows
through a double articulated lever to the crosshead.
2. Crosshead Lubrication
The crosshead lubricating oil flows from the oil inlet (OI) through the support (4,
Fig. 1), the bottom lever (6) and the top lever (7) to the connecting piece (8). The
connecting piece (8) is attached to the connecting rod (10). The oil enters the ring
space (RS) through the bore (12). The crosshead pin (11) is lubricated through bores
in the top end bearing shell (9). The oil flows through the bore (OB) through the
connecting rod (10) to the bottom end bearing.
