F112003 Reduction gear for marine turbine (About 5m diameter gear machining process)

Abstract

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.
