摘要： The sealing of a turbine casing is reinforced by decoupling a fastening flange from a remainder of a housing. The casing includes a body that is externally reinforced by axial ribs that are connected to an annular rib and the fastening flange is attached to the annular rib by an annular wall portion that is thinner than the annular rib and than the flange.

摘要： In a disengageable axial abutment for a rotary machine fitted with fluid bearings, an outer ring (103) comprises first and second outer half-rings (103A, 103B) centered in the casing (111) by a flexible suspension system, with the outer half-rings (103A, 103B) being held in the axial direction between a static abutment member (113) and a pre-loading system (104) exerting a predetermined axial force such that, so long as the axial load exerted on the axial abutment via a synchronization cone (108) is greater than a given threshold, each rolling element (101) presents a single line (121) of two points of contact (121A, 121B) with an inner ring (102) and with the first outer half-ring (103A) respectively, and the inner ring (102) is driven in rotation by the synchronization cone (108), whereas, when the axial load exerted on the axial bearing becomes smaller, a gap (115) is created between the outer half-rings (103A, 103B) and a second line (123) of two additional points of contact (123A, 123B) is created between each rolling element (101) and the inner ring (102) and the second outer half-ring (103B) respectively, such that the axial abutment is disengaged.
