FIELD: machine building.SUBSTANCE: invention relates to a device to create mechanical prestress, intended for the provision of mechanical contact between rolling elements and their race groove. The device (10) to create mechanical prestress passing around some axis (A) between the first plane being, in essence, perpendicular to this axis (A) and the second plane being, in essence, parallel to the first plane and shifted in axial direction in respect to it. The device comprises the first ring body (13) passing in the said first plane and the first pool of tabs (15) consisting of at least three tabs, every tab is coupled with the first body (13) and passes, mainly, in the radial direction, every tab from this first pool comprises flat surface (17) passing in the said second plane. In particular, the device is used in a rotor, namely, in the rotor of a gas turbine engine airscrew not covered by a fairing.EFFECT: provision for surface contact between the parts of the elements subject to the action of the mechanical prestress.9 cl, 4 dwg |
