Rotary thermal machine`s e.g. steam turbine, inner housing, has housing parts with predetermined wall thicknesses, where sum of thicknesses of overlapping sections is equal to wall thickness of housing parts in overlapping areas

摘要

The housing has lower and upper housing parts (12, 13) with two overlapping areas in an area of a separation plane, where the overlapping areas are opposite to each other. The housing parts overlap each other with two overlapping sections (17, 18) and are removably connected with each other. The housing parts have predetermined wall thicknesses, where sum of thicknesses of the overlapping sections is equal to the wall thickness of the housing parts in the overlapping areas.
