Abstract
An exhaust case for a turbomachine includes, from outside towards inside, yokes, a collar and a hub, which are annular and coaxial. The hub is connected to the collar by radial arms and extends between an annular flange and an inner collar capable of guiding a gas flow. In the hub each arm includes a rib in a shape of a triangle which ends with the flange. The inner collar is extended into the hub by a plate capable of transferring forces between the flange and the yokes. The plate can be advantageously inclined with respect to a radial plane. Two portions, which enclose a cut-out formed in a minimum-stress region along the plate, are coupled with pre-set plays. The case is capable of absorbing compression and traction at a thermal gradient.
