Abstract

The invention relates to mechanical engineering, in particular, to devices for connecting machine parts that mate along cylindrical surfaces. The purpose of the invention is to expand the operational capabilities by ensuring the detachment of the connection with limited access in the radial direction. Covered 1 and female 4 parts are connected to one another with a split spring ring (K) 3. installed in coordinated grooves made on the mating surfaces of the parts. K 3 is provided with an eccentric section, the radius of which is B 3 of the peripheral radius K 3. The circumferential displacement K 3 is limited by a limiter. In the gripping part of the rest part 4, the holes for the tool insertion are made when disassembling the connection. 4 il.

Description

Fy

The invention relates to mechanical engineering, namely to devices for connecting machine parts mating on cylindrical surfaces.

It is known to connect parts that mate along cylindrical surfaces, the axial fixation of which is carried out by a split ring placed in a circular groove made on the outer surface of the male part, axial holes for screws are screwed into threaded holes made by the female part.

A disadvantage of the known compound is the relatively large labor intensity of its manufacture and assembly.

It is also known to connect coaxial cylindrical parts with fixation in axial stress relative to each other by a split spring ring disposed in matched grooves made on the mating surfaces of the parts to be joined, which are provided by radial holes formed in the walls of the outer part, allowing compression of the ring .

However, when using a known joint, it is required to apply large axial forces during assembly. In addition, when disassembling, there are difficulties with. limited access to radial enveloping parts.

The purpose of the invention is to expand the operational capabilities by ensuring the separability of the connection with limited access in the radial direction.

The goal is achieved by the fact that the split spring ring, having - ot in matched annular grooves, EXHAUSTED on the mating cylindrical surfaces of the parts to be connected, is provided on the outer circular surface in the zone of the pier with eccentric sections of a larger radius. The movement of the spring ring in the circumferential direction is limited by the locking pin. inserted into the covered dotal and located in the spring holtz connector, and in the grasping part holes for the tool insertion are discharged when disassembling the connection.

FIG. 1 shows the connection details. longitudinal times, php. 2 is the same, top view: in FIG. 3 - p;) 3re.noe spring ring, top view: on the phi, .4 connection, top view with the removed fitting part

Compound soy gots from detail 1, or narcxi, .-. fu,.-.-. s.gi which

an annular groove 2 is made in which the split spring ring 3 is located. The female part 4 has an annular groove on the inner surface,

matched with groove 2. There are holes 5 in the female part A, parallel to the axis of the joint and serving to disassemble the joint. The spring ring 3 on the outside cylindrical surface is provided in the connector area with eccentric sections of a larger radius 6, and the male part 1 is provided with a pin 7 located in the spring ring connector 8 and intended for

fixing the latter in a circumferential direction,

Assembly assembly order is as follows.

In the groove 2 of the male part 1, plant a split spring ring 3. Then, in place of the connector 8 of the spring ring 3, a locking pin 7 is installed in the male part 1, and then the female part 4 is pulled until the spring ring is fixed to the female part 4.

To disassemble the joint, a tool in the form of pins is inserted into the holes 5. In this case, due to the elastic deformation in the radial direction, the spring ring 3

will be recessed into groove 2, and the joint is unlocked. In the case of KOI and when disassembling the joint, the pin falls into the area of the spring ring connector or abuts against its side surface, it is necessary

rotate the female part around the axis of the joint. In this case, the pin enters the area between the eccentric section of the spring ring and the inner surface of the female part, the spring

the ring is deformed in the radial direction and the compound is uncoupled.
