<p>Abstract : The objective is to reduce maintenance inspection costs by enabling the liner and the stator to be easily extracted from the housing of an electrical generator and enabling the replacement of only the liner and the stator. The electrical generator housing (35), which houses a hollow cylindrical liner (42) and a stator that is arranged in the radial direction inside this liner (42), has a separable structure enabling separation into two parts in a plane that includes the axis of rotation of a rotary shaft. In the interior of the electrical generator housing (35) there is provided a ring-shaped member (49), which is equipped with a hole (45) that supplies a cooling medium to a passage (43) formed within the liner (42) and a hole that discharges the cooling medium from the passage (43), and which, at each joint with the passage (43), is equipped with a surface (49a) that opposes the liner (42) and a back face (49b) that opposes the electrical generator housing (35), and in the center of which is provided a through-hole (50) that connects the hole (45) and the passage (43) and a through-hole (50) that connects the hole (45) and the passage (43).</p> |
