Abstract
A turbomachine comprises a primary rotor part and a secondary rotor part mounted to the primary rotor part for joint rotation therewith. The primary part and secondary parts have a tight fit between a radially inner diameter surface of the secondary part and a radially outer diameter surface of the primary part. The primary part has a radial stop operable to limit centrifugal growth of the secondary part when a maximum operating speed of the primary rotor is exceeded. The radial stop includes a radially inner surface facing an associated radially outer surface of the secondary part. When an operating speed of the primary part is inferior to the maximum operating speed, the radial stop of the primary part and the associated radially outer surface of the secondary part are spaced by a radial gap sized to close when the maximum operating speed is exceeded.
