MACHINE STATOR AND ASSEMBLY AND DISASSEMBLY METHODS

摘要

The elements of a casing portion are formed of consecutive shells (12, 13, 14) in line with grooves (19, 20) designed to house roots (23) of guide vane stages (21, 22) which are fixed in place by springs (26) and pins (29) for stopping rotation. The elements (12, 13 and 14) are arranged in a complete circle, and the assembly is made by axially separating them to insert the elements of the guide vane stages (21, 22) between these elements by a radial movement.
