COMBINED MOTIVE POWER APPARATUS AND SHIP EQUIPPED WITH SAME

Document Type and Number:

WIPO Patent Application WO/2015/029898

Kind Code:

A1

Abstract:

　Stress caused by thermal expansion of a turbine is prevented from reaching a clutch device, the quantity of flexible joints is reduced, a combined power generation apparatus is reduced in size, the building cost thereof is reduced, and alignment precision is improved. A combined power generation apparatus (30), wherein, of a power turbine (2) and a steam turbine (3), at least the turbine having the greater amount of thermal expansion (e.g. the steam turbine (3)) is secured at one end in an axial direction (L) thereof as a thermal expansion origin point (11) to a top surface of a base part (1), and the other end in the axial direction (L) is disposed as a thermal expansion movement point (15) so as to be capable of moving only in the axial direction (L) relative to the top surface of the base part (1). A relative movement structure (A) is provided for preventing stress caused by the movement of the thermal expansion movement point (15) from reaching a clutch device (7). The relative movement structure (A) is a structure in which, for example, the thermal expansion origin point (11) is oriented to the clutch device (7)-side of the steam turbine (3), and the thermal expansion movement point (15) is oriented to the side of the steam turbine (3) opposite the clutch device (7).
