Description

Circlip made of flaehm material

The invention relates to a locking ring which is used to secure shafts with a pierced groove against axial Shift is used.

There are a large number of such security elements are known, all of which have the purpose of a shaft with pierced Secure the groove against axial displacement. The circlips are punched from tape material or Bent wire.

These known designs have various disadvantages caused by the shape or the method of manufacture. Out Circlips punched from band material require a relatively high amount of material, which is reflected in the pricing such a mass part has an unfavorable effect. Another disadvantage of these circlips is the low radial suspension, which - although sufficient in most cases - for some areas of application and with rough tolerances of the groove, often not enough. Circlips made of round wire are rarely used because of the round edges of the ring require a very deep recess in order to prevent the locking ring from jumping out under axial load. Out Retaining rings made of square material are also made for some applications. Have these rings In addition to the low resilience, the disadvantage that a warping of the inner edges occurs at the bending points must be eliminated again by leveling.

Retaining rings made from flat wire do not have the disadvantages of round or square wire, but they must be designed in this way

Leaves - make sure that they rest securely in the groove so as not to fall into jump out in the radial direction, as well as offer sufficient security against displacement in the axial direction.

The locking ring according to the invention is designed in such a way that it springs into the rage with good springiness at several points in the. The bottom of the groove and absorb large axial forces can.

The drawing shows the invention in 3 exemplary embodiments.

Fig. 1 shows a locking ring (1) made of flat wire or flat material, which rests in a hat (16) of the shaft (15) at 3 points (2, 3, ¹ O and has good suspension in the direction AB,

Fig. 2 shows the side view of the shaft (15) with attached Circlip (1) «

Fig. 3 shows a locking ring (1), the larger to improve the radial suspension in the direction A-B Has arcs (5) and bears against the points (6, 7 »8) in the groove (16) of the shaft (15).

Fig. H shows the side view.

Fig. 5 shows a locking ring (1) made of flat wire or Flat material, which has good radial resilience in direction A-B due to the arches (9), but is shaped in such a way that to increase the axial load capacity 5 support points namely 1o, 11, 12, 13, U in the groove (16) of the shaft (15) available.

Fig. 6 again shows the side view.
