Description

Изобретение относитс к машиностроению и может быть использовано дл соединени деталей, в частности дл осевой фиксации деталей типа ва- Лов в отверсти х. The invention relates to mechanical engineering and can be used to join parts, in particular for axial fixing of shaft-like parts in holes.

Цель изобретени - упрощение конструкции и облегчение сборки.The purpose of the invention is to simplify the construction and ease the assembly.

На фиг, 1 изображено резьбовое соединение деталей, общий вид; На фиг. 2 - элементы устройства.Fig, 1 shows a threaded connection of parts, a general view; FIG. 2 - elements of the device.

Базова деталь 1 вьтолнена с двум или более резьбовыми отверсти ми 2, Присоедин ема деталь 3 выполнена с отверсти ми 4. Крепежный элемент содержит резьбовый участок 5, цилиндрическую часть 6 меньшего диаметра и головку 7.The base part 1 is complete with two or more threaded holes 2, Attachment part 3 is made with holes 4. The fastening element contains a threaded section 5, a cylindrical part 6 of smaller diameter and a head 7.

Межосевое рассто ние А между резьбовыми отверсти ми 2 базовой детали 1 больше или меньше межосевого рассто ни А между отверсти ми 4 .присоедин емой детали 3 на величину разницы наружного диаметра резьбы и диаметра цилиндрической части 6. The center distance A between the threaded holes 2 of the base part 1 is larger or smaller than the center distance A between the holes 4. The attached part 3 is the difference in the outer diameter of the thread and the diameter of the cylindrical part 6.

Длина цилиндрической части 6 равна глубине отверсти 4 в присоедин емой детали 3,The length of the cylindrical part 6 is equal to the depth of the hole 4 in the attached part 3,

Установка детали 3 в процессе сбор ки узла проводитс с предварительно продетыми в отверсти 4 крепежньши элементами и со смещением последних до соосного совпадени с резьбовыми отверсти ми 2, при этом необходимо синхронное завинчивание крепежных элементов.The installation of the part 3 in the process of assembling the assembly is carried out with the fastening elements previously threaded into the holes 4 and with the latter displaced to coaxially coincide with the threaded holes 2, and simultaneous screwing of the fastening elements is necessary.

Отвинчивание тоже должно быть строго синхронным, чем и обеспечиваетс самостопорение узла, так как при содрагани х, вибрации издели и других факторах, вызывающих само- повиззольное отвинчивание резьбовыхUnscrewing must also be strictly synchronous, which ensures the self-stopping of the assembly, since during shaking, vibration of the product and other factors causing self-susceptible unscrewing of the threaded

Claims

1. A threaded connection of parts containing fasteners installed in non-axial holes of the base and attachable parts, each of which is made with a head, a threaded section and with a cylindrical part of smaller diameter on the side of the head placed in the hole of the part being attached, This is due to the fact that, in order to simplify the design, the center distance between the holes of the base part is more or less than the center distance between the holes connected by the value of the difference of the outer diameter of the thread and the diameter of the cylindrical part, and the length of the cylindrical part is equal to the depth of the hole in the attachment part.

2. The method of assembling a threaded joint of parts, including the operations: installing fasteners in the holes of the part to be joined, screwing them into the threaded holes of the base and shifting relative to the holes of the connected part, characterized in that, in order to simplify installation, after installing the fasteners in the holes The part being joined is displaced to a coaxial arrangement with the threaded holes, and screwed in simultaneously.
