Beschreibung
Zusammenfassung:	FIELD: machine building.SUBSTANCE: group of inventions relates to machine building. The pre-stressing device (10) contains at least three deformation zones (11). Deformation zones (11) contain at least one flat contact surface and pass in the first plane. Between each deformation zone (11) there is a flat contact surface (12) passing in the second plane. The rotor without fairing propeller for the gas-turbine engine contains the named pre-stressing device.EFFECT: decrease of wear of pre-stressed details is achieved.7 cl, 3 dwg Группа изобретений относится к машиностроению. Устройство (10) создания предварительного напряжения содержит по меньшей мере три зоны (11) деформирования. Зоны (11) деформирования содержат по меньшей мере одну плоскую контактную поверхность и проходят в первой плоскости. Между каждой зоной (11) деформирования содержится плоская контактная поверхность (12), проходящая во второй плоскости. Ротор без винта обтекателя для газотурбинного двигателя содержит указанное устройство для создания предварительного напряжения. Достигается снижение износа деталей, подвергающихся предварительному механическому напряжению. 2 н. и 5 з.п. ф-лы, 3 ил.
