Abstract

The invention relates to locking devices and can be used to prevent axial mixing of axes, rollers, fingers, etc. The purpose of the invention is to simplify the assembly and disassembly of the connection. The assembly comprises an axis 1 with two intersecting transverse holes. In one of the holes is located the middle part of the elastic wire element (PE) 4, and in the other - the ends 5 of PE 4. On the axis in the plane of placement of the transverse holes there is an annular groove to a depth at least equal to the diameter of the CE 4 in its cross section. The end part of the axis 1 has a retainer 7, made with wedge surfaces 9 and an open diametral groove in which the middle part of the CE 4 is placed, as well as a screw 8 acting on the retainer 7, Retainer 7 with wedge side surfaces 9 interacts with the ends 5PE 4. This design embodiment of the device eliminates the need to extract the CE 4 from the hole 1 during assembly and disassembly. 3 il. (L 11 with so with so; about N) figure 1

Description

The invention relates to general engineering, namely to locking devices, and can be used to prevent axial displacement of axes, rollers, pins, etc.

The purpose of the invention is to improve the installation and disassembly conditions of the joint by eliminating the need to remove the wire element from the diametrical hole of the shaft.

FIG. 1 shows the proposed site, a longitudinal section; in fig. 2 shows section A-A in FIG. one; in fig. 3 - the position of the wire element at the time of installation or disassembly of the connection

The assembly comprises an axis 1 with two intersecting transverse holes 2 and 3. In the opening 2 there is a middle part of the elastic wire element 4, and in the opening 3 there are ends 5 of the wire element 4.

On the axis i, in the plane of placement of the transverse holes 2 and 3, an annular groove 6 is made to a depth at least equal to the diameter of the wire element 4 in its cross section.

In the end part of axis 1, a retainer 7 is installed, made with an open diametral groove in which the middle part of the wire element 4 is placed, and a screw 8 in contact with the end face of the retainer 7. The retainer 7 has wedge surfaces 9 which interact with the ends 5 of the wire element 4. Axis 1 has enclosing parts 10 and 11. The connection is disassembled as follows.

Unscrew the screw 8 (Fig. 3). When this wire element 4 under the action of elastic forces exerts its ends 5 on the wedge side surfaces 9 of the retainer 7, as a result of which the latter moves along the axis of the face hole, and the wire element 4 is placed in the annular groove 6 on the diameter not exceeding the diameter of axis 1 Axis 1 is then disconnected from parts 10 and 11 enclosing it.

I

Parts 10 and 11 are mounted on axis 1. Then screw the screw 8. In this case, the retainer 7, moving, acts with its wedge side surfaces 9 on the ends 5 of the wire element 4, spreads the wire element 4 by the diameter that exceeds the diameter of the holes of the parts 10 and 11. Thus, the axis 1 and the parts 10 and 11 surrounding it are fixed against axial displacement.

Such constructive performance

The assembly greatly simplifies installation and disassembly of the joint by eliminating the need to remove the filler element from the axis during disassembly and re-bend it during assembly.
