Flexible Gearbox Applications

We offer full customization of shaft arrangements. The following illustrations show the three usual configurations:

H-gear configuration

This is the standard configuration and is recommended when available space allows it.

Gearbox Configuration H

U-gear configuration

This is the best solution when space is limited.

Gearbox Configuration U (2)-1

 

PTI-gear configuration

This is the most flexible configuration. Depending on the desired speed and/or if the design of the vessel calls for two small engines instead of one large engine; the propeller can be run optimally on one or two engines. This configuration is ideal for the hull of catamaran vessels.
