Definitions

  • the invention concerns a substantially C-shaped, resilient coupling means of the type stated in the introductory portion of claim 1.
  • the known coupling means of this type substantially have the shape of circular arcs and will frequently be so positioned in the space defined by the grooves that at any rate long extent thereof are present in the dividing face between the two parts.
  • the coupling means has to be cut through. This takes place by the scissors effect which is produced when the two parts are pressed away from each other.
  • the coupling means is constructed as stated in the characterizing portion of claim 1, the cut amount of material is greatly reduced and cutting is correspondingly easier to perform.
  • the coupling means has such as shape as is stated in claim 2, its central line intersects the dividing face between the two parts at four points, and cutting will then take place along relatively short faces positioned around these points.
  • fig. 1 shows an axial section through two coupled cylin ⁇ drical parts with ring-shaped grooves in which a substan ⁇ tially C-shaped coupling means of ordinary known type is positioned
  • fig. 2 shows a section along the line a-a in fig. 1,
  • fig. 3 shows a section analogous to that of fig. 1, but with a coupling means of the invention positioned in the grooves,
  • fig. 4 shows a section along the line c-c in fig. 3
  • figs. 5 and 6 show sections along the lines e-e and f-f, respectively, in fig. 4.
  • 10 and 11 are two coaxial ring-shaped parts which are coupled together along coaxial, cylin ⁇ drical faces 12.
  • the inner part 10 may e.g. represent a ball bearing and the outer part 11 a means which is rotatably journaled by means of the ball bearing.
  • the parts In the cylindrical faces 12 engaging each other, the parts have oppositely positioned ring-shaped grooves 13 and 14, respectively, which mount a resilient, substantially C- shaped coupling means 15 which prevents relative axial movements of the two parts.
  • the known coupling means 15 is sub ⁇ stantially circular when it is positioned in the ring- shaped space formed by the grooves 13 and 14, and engages the bottom of the outer groove 14 substantially along its entire periphery under the action of its own spring force.
  • the coupling means 15 When the two parts 10 and 11 are to be disassembled, e.g. with a view to replacement of a ball bearing, the coupling means 15 must necessarily be cut through, which takes place by pressing the parts away from each other in the axial direction such that cutting takes place at the groove edges.
  • the cutting zone is shown at a dotted line 16 in fig. 2, and it will be seen that this zone extends through the entire length of the coupling means and even extends along a diameter of the cross-section, so that it is a large amount of material which has to be cut through, which requires a correspondingly great force.
  • Figs. 3-6 show the same two parts 10 and 11 with ring grooves 13 and 14 and a cylindrical engagement face 15, like in figs. 1 and 2, but with a coupling means 17 according to the invention positioned in the grooves.
  • This coupling means is substantially oval so that two dia- metrically oppositely positioned portions 18 of the means are present in the outer groove 14 alone, and two other diametrically oppositely positioned portions 19 separated about 90° from the first ones are present in the inner grooves 13 alone.
  • the dividing line 20 of the coupling means which is shown in dotted form, thus intersects the engagement face 15 at four points and the cutting zone is reduced to and divided into four relatively short subzones 21 positioned around the four points of intersection. Each subzone passes obliquely through the coupling means and thus through the thickest portion thereof only at a single point.
  • the coupling means does not have to be oval, but may e.g. be wave-shaped or - 4 -

Abstract

Dispositif élastique de couplage sensiblement en forme de C (17) apte à se monter dans un volume annulaire formé de deux rainures opposées (13 et 14) ménagées dans des faces cylindriques (12) en contact l'une avec l'autre de deux pièces coaxiales (10 et 11). Le dispositif présente une forme autre que celle d'un arc de cercle de sorte que certaines parties dudit dispositif de couplage soient positionnées entièrement dans l'une des rainures, tandis que d'autres sont positionnées entièrement dans l'autre. On peut ainsi réduire la force nécessaire pour couper le dispositif de couplage lorsque l'on veut démonter les deux pièces (10 et 11) puisque la zone de coupe (21) est amenuisée.
