Abstract
The stress- strain state of stator - spiral chamber systems of the hydraulic machines are considered on the basis of three-dimensional finite element model. Investigations of the distribution and localization of the stress in the systems types carrier and non-carrier are considered. The main stress localization zones are places in compounds of stator rings and meridional stiffeners with spiral chamber shell are shown. The results of research are carried out for the real objects, which allows to make recommendations to ensure their strength.
