SU66526A1 - Bolted joint - Google Patents

Description

The proposed bolted joint, in contrast to the well-known ones, is made in the form of a bolt, on the rod of which, when fitted into the hole of the parts to be joined, there are auto nozzles of short metal rods connecting from both rings with rings or an attachment of rods from one end of them, inserted Insert into the hole of the parts to be joined together with the bolt rod.

The nozzle is used to provide pre-C) Bolt-fitting bolts due to the spiking of the rods in the bore of the parts to be joined, which are made with coarse tolerances.

In FIG. 1 shows a bolt without an “upset”; FIG. 2 - a bolt with a nozzle attached to its rod; FIG. 3 is a variant of the bolt, FIG. 4 - version of the nozzle.

On the bolt rod 1, there are two bore holes 2 1NOD rings 5, a top and, which fasten metal rods 4, which are located along the forming surfaces of the bolt rod (Figs. 1 and 2). Last has a rectangular through hole

for tension wedge pin 5.

The bolt 6 of another embodiment (Fig. 3) has the same hole for the tension wedge; Spindle 5. When this bolt is fitted, another patch is inserted into the last hole in the last part of the bolt, consisting of 6 genuine rods fastened with a ring 8; | from one end.

Pressing the bolt to fit ensures the reliability of the connection due to the cm of the rod;

Subject invention

Bolted connection, characterized in that, in order to press the fit of the bolt into the holes of the parts to be joined, made with coarse tolerances, the rods 4, 7 are attached, which are connected to each other from one or both ends by rings and are located in the holes in the circle. forming a bolt along with it in order to provide a press fit due to their removal.
