F112003 舶用主機タービン向け減速歯車の紹介(5mクラスの大型歯車の製造について)

抄録

In the history of ships, steam turbine has been adopted as the main engine for many years. Ships to be mounted steam turbine as a main engine have been decreasing due to economic problems such as fuel efficiency in today. That though, the Liquefied Natural Gas Carriers (LNGC) only adopts steam turbine as the main engine. This presentation introduces the main steam turbine engine for LNGC, and explains machining technology of large high-precision reduction gear such as 5m diameter.
