Description

Locking ring made of flat wire

The invention relates to a locking ring that is used to secure Shafts with a grooved groove are used to prevent axial displacement

A large number of such precautionary elements are known which all have the purpose of a shaft rait plunged groove against axial To secure displacement · The circlips are punched from strip material or wire is bent.

These known designs have different, by the shape or the manufacturing process-related disadvantages. Circlips stamped from strip material require a relatively high amount of material, which is has an unfavorable effect on the pricing of such a mass-produced item. Another disadvantage of these circlips is the low radial resilience, which - although sufficient in most cases - for some areas of application and in the case of rough tolerances of the groove, it is often not sufficient. Circlips made of round wire are rarely used because the round edges of the ring require a very deep penetration in order to prevent the locking ring from jumping out under axial load. Retaining rings made from square material are also made for some applications. Have these rings In addition to the low resilience, the disadvantage is that the inner edges warp at the bending points, which is eliminated by leveling must become.

Circlips made of flat wire do not have the disadvantages of round or square wire, but must be designed in such a way that they rest securely in the groove so that they do not jump out in the radial direction, and also offer sufficient security against displacement in the axial direction.

The locking ring -gem. Invention- is designed so that it is well resilient jumps into the groove, the hat rests at several points in the bottom and

can absorb large axial forces. Furthermore, through the special Design of the locking ring, the popping out of the locking ring prevented from the groove.

The drawing shows the invention in 3 exemplary embodiments «

Fig. 1 shows a shaft with a screwed-in groove (3) into which a locking ring (1) is inserted. The opening of the locking ring formed by points 4 and 5 allows it to be pushed onto the shaft.
The hook (6) formed on a resilient leg prevents the locking ring from slipping off.

Fig. 2 shows the side view of the shaft (2) with the locking ring (1) inserted.

Fig. 3 shows a locking ring (1) pushed into a groove (3) of the shaft (2), the resilient legs (7 and 8) are bent so that it is easy to push onto the shaft, but it can jump off inwardly bent leg (8) is prevented.

Fig »4 shows the side view.

Fig. 5 also shows a locking ring (1) pushed into a groove (3) in the shaft (2) cause relatively large opening of the locking ring when sliding. This large opening path is made possible by the relatively large arches (io and 9).

Fig. 6 again shows the side view.
