Abstract

The invention concerns a device for fixing in place a wire locking-ring (1) which is located in an annular groove (5) in the interior wall of a bore (6) in a working part and is stressed in the axial direction. In order to ensure that locking-ring formed by the annular wire is properly aligned with the components it is intended to hold together, and in order to make the ring tamper-proof, the ring is placed during assembly in the bore at the end of a conical sleeve (4) and against an element (20) which is rotationally symmetrical with respect to the axis of the bore and which is formed by a shaft or cap element, etc., the ring automatically engaging in the annular groove provided for this purpose.

Description

State of the art

The invention relates to a device for fixation a locking wire ring according to the genus of Main claim. Find devices of the named type their possible uses mainly in the area of Hydraulics, brakes, anti-lock braking systems, etc. The mainly designed as locking wire rings Fasteners require perfect Mon days and protection against manipulation, as their Failure in the listed areas of application safety-relevant consequences.

From DE-OS 23 10 927 is a device for fastening supply of a part with a circular cross-section known the features of the invention the loads of Ringes by the forces acting on him to be worn. Such a wire arrangement can be dismantled if De mounting holes for radial compression of the wire be arranged around. The omission of this demonta The wire arrangement would be perforated against unauthorized persons Secure manipulations. However, there is Possibility of retrofitting the disassembly holes to attach, especially in the event that the outer Component is not hardened.  

Advantages of the invention

In a device of the type mentioned by the in the characterizing part of the main claim specified features ensuring the orderly moderate alignment of the locking wire ring relative to the components to be held together and the protection of the Wire arrangement reached before unauthorized access.

By pressing the locking sleeve flush into the The workpiece hole is the one on the angled forehead side of the locking sleeve ring between the inner wall of the workpiece bore and the axially flattened outside of the hole axis rotationally symmetrical element in the outside, the inner wall of the cylindrical movement circular ring groove pressed and snaps there cher and completely in this one. The proper one Seat of the locking wire ring in the ring groove is there ensured by. The securing sleeve forms furthermore protection against unauthorized persons Manipulations, as access to the in the ring groove inserted locking wire ring is no longer possible is.

The corrosion protection of the locking wire ring is through an appropriate selection of the material guaranteed.

Since the securing sleeve is preferably formed from sheet metal is, their tight fit is a press fit reachable. By choosing the sleeve material is a additional corrosion protection for the wire ring through has a long-range effect.

The proposed locking sleeve therefore ensures perfect installation and protection against tampering  inexpensive to manufacture and lighter Mountability.

drawing

The invention is described below with reference to the drawings explained in more detail. Show it:

Fig. 1a and 1b is a side view of the inventive device SEN in cross-section,

Fig. 2 shows the securing sleeve of the device according to the invention shown in Fig. 1a, b in cross section.

. 1a and 1b of the fuse wire ring 1 formed by an annular wire arranged as shown in Fig. The securing wire ring 1 is shown in Fig. 1a in a through stage of assembly, while it is shown in the position shown by Fig. 1b Darge in its final position. The final position of the locking wire ring 1 is achieved during assembly by running it on the end 3 of the locking sleeve 4 , which is rotationally symmetrical to the bore axis element 2 - based on the drawing - and then inevitably into the best from an annular groove 5 The securing groove engages in the inner wall of the cylindrical workpiece 6 . The locking wire ring 1 is therefore covered in the assembled final state by the hedging sleeve 4 , whereby corrosion and protection against manipulation is ensured, since an effect from the outside on the locking wire ring 1 is no longer possible in this position. The tapered securing sleeve 4 on its end face 3 ensures due to its shape formed from sheet metal that the tight fit of the locking wire ring 1 in the annular groove 5 is achieved by an interference fit in the final assembly stage. The location of the securing sleeve 4 in the final stage of assembly is shown by Fig. 1b. During the assembly process, the securing sleeve 4 is pressed flush with the inner wall of the workpiece bore into the workpiece 6 against the element 2, which is rotationally symmetrical with respect to the bore axis. The element 2 , which is rotationally symmetrical to the bore, can be formed by a shaft or a cover element. Since the final position of the safety wire Ges 1 is reached in the position shown in FIG. 1b at the end of the assembly process.

The securing sleeve 4 shown in cross section in FIG. 2 has a punched-out 7 on its end face 3 which, during the assembly process, faces the element that is not apparent from the drawing and is rotationally symmetrical to the bore axis. This punching 7 ent is characterized in that the cup bottom is punched out of the cup-shaped securing sleeve 4 on its end face 3 . During the assembly process, a rotationally symmetrical to the bore axis member 2 is fed, which, as shown in FIG. It can be seen 1, on its side facing the securing sleeve 4 side is flattened conical and meets with egg nem lower in this field diameter in the punched-out 7 of the security sleeve 4. The hedging sleeve 4 has in its area facing the axis of rotation rotationally symmetrical element 2 a concentric angle of about 45 ° to - based on the drawing - horizontal. This is necessary because the securing sleeve 4 is inserted flush with the inner wall of the workpiece bore during the assembly process and therefore the securing sleeve 4 must have a shape in its upper area which has sufficient space for the securing sleeve ( 4 ) in this area. overlying locking wire ring 1 can, in order to bring about a snapping of this locking wire ring 1 into the annular groove 5 in the final phase of the assembly process.

A possible blocking of the locking wire ring 1 during the assembly process, due to the Ausfor mung of the rotationally symmetrical to the bore axis Ele component 2 taken into account, since this in his Si cherungshülse 4 facing portion having a conical From flattening and meets reduced diameter in the securing sleeve. 4
