Description

наружной поверхности в стенки отверсти  8..лроисходит деформаци  конусной части 6 гайки 4 в нределах упругости, что приводит к обжатию части внутренних витков резьбы , и заклинивание гайки на резьбовом хвостовике болта 1, исключающее самоотворачивание гайки 4 в услови х действи  вибрационной нагрузки.the outer surface of the wall of the hole 8. there is a deformation of the tapered part 6 of the nut 4 within the limits of elasticity, which leads to the compression of part of the internal threads, and the jamming of the nut on the threaded shank of the bolt 1, which prevents the nut 4 from unscrewing under the action of the vibration load.
