Operation
DONG-I MARINE TRANSMISSION consists of a pair of hydraulic
clutches and a reduction gear. It is the power transmission
unit which transmits the power generated by the engine
to the propeller. The major function of marine transmission
is forward, neutral and reverse in propulsion and certain
Rate of Reduction speeds.
Main features
- 13 models covering almost all applications up to
470HP
- Robust design to withstand continuous duty for workboat
- Precise gear for long life and smooth operation
- Smaller size than other transmissions of similar
capacity
- Only sintered disc is applied. No Paper friction
Defination of continuous duty for work boat
In the work boat applications, Marine transmissions
are expected to operate continuously at full engine
governed speed. For continuous day-long or around-the-clock
service, propulsion engine power setting must be within
the marine transmission's allowable input rating. Most
displacement hull vessels are powered for continuous
duty. However, the actual marine transmission power
loading depends on :
- the propeller
- the vessels work assignment
- the condition of throttle setting during continuous
service
We recommends that all displacement and semi-displacement
hull commercial applications be classed as continuous
duty usage of the marine transmission.
Example : Fishing trawlers, Tugs, Ferries, Ocean freighters,
Offshore supply boats, Research vessels.
