Abstract
The invention relates to a part of revolution () intended to be rotated, comprising a hub () intended to be tightly adjusted on a rotary shaft (), and a body () extending radially outwards from an axial end of the hub. In order to increase the critical speed up to which the tightening can be retained, the hub () comprises three relatively thick annular regions () separated from one another by two relatively thin annular regions (), in such a way that when the part of revolution is subject to a centrifugal force (F), the two relatively thin annular regions () form privileged deformation zones acting as a double pivot. Such a part can advantageously be used as a piston for balancing in a turbine test bench or in a turbomachine.
