Product Profile of Marine Gear System[pls 71]

The pls type gear units are designed on planetary principle with co-axial input and output shafts to drive the offshore Patrol vessel with cp propeller, optimizing the space requirement of the main propulsion.With a capacity range of 1,500 kw to 10,000 kw and reduction ratios of 1.5 to 4.8, they meet all known requirements of fast vessels.

• These gear units have-

-low weight-power ratio, thereby increasing the ship’s pay load
-excellent anti-shock properties due to low gear unit mass
-cushioned speed changing processes allowing torque to be adapted to engine characteristics
-high efficency as a result of having been designed as a planetary gear unit and due to automatic separation of discs of multi-disc clutch even if installed in inclined position, and are compact, thereby allowing favourable design of engine room.
-a clutch actuating hydroneumatic system which is designed for gradual engagement. This actuating system and the forced lubrication system are provided with local and remote monitoring/control facilities, interlocaking various failure modes.
