Definitions

  • the invention relates to a circlip with an insertable into a receiving groove of a shaft or a bore ring body having an annular gap between the same gap-side end portions, which in the radial direction on the side facing away from the receiving groove in use relative to the adjoining Widened portion of the annular body to compensate for an occurring by different centrifugal forces with a rotating ring unbalance.
  • a circlip of this type also referred to as a snap ring, is specified in AT 179450 B. The circlip is slotted to widen it against its elasticity and to push over a shaft and snap into a receiving groove incorporated therein.
  • the ring body has a radial width which continuously changes over its circumference, reaches a maximum diametrically opposite the slot or annular gap and continuously decreases to the annular gap on both sides to the same extent, the gap-side end sections having widened ears with holes for insertion of pliers tips see are.
  • the end sections are also dimensioned in their radial width and in the circumferential direction extending length so that in the rotation due to the different ring width or mass distribution resulting centrifugal forces are balanced.
  • the different radial width can be associated with disadvantages for the manufacture and function, such as the axial support of components on the shaft.
  • the present invention has for its object to provide a retaining ring of the type mentioned with improved for the production and function Eigen-create.
  • annular body except for the end portions has constant cross section and the mass of the end portions per unit length in the circumferential direction is chosen so that the caused by the annular gap imbalance is balanced.
  • the ring body which has the same radial width except for the end portions, can be produced advantageously and precisely and results in a stable, circumferentially uniform support surface and receiving axially acting forces.
  • the lying on both sides of the annular gap end portions are dimensioned in their radial width so that an imbalance that would occur due to the missing mass in the gap area is compensated or balanced.
  • the two end portions are symmetrically formed with respect to the bisector of the gap opening angle.
  • An advantageous embodiment for the production and function consists in the fact that the circlip in its free non-use state is formed out of round to such an extent that when inserted into a receiving groove over its entire circumference evenly rests on Nutground, the dimensioning of the end portions is tuned to compensate for the imbalance in the inserted state.
  • the compensation of imbalance due to the uniform mass distribution in the circumferential direction in use is further improved and in addition also achieved a precise fit of the locking ring in the receiving groove, so that the axial support forces are distributed homogeneously over the circumference of the ring body.
  • Fig. 1 shows an embodiment for explaining the invention.
  • the slotted securing ring 1 has an annular body 10 with an annular gap 12 of width s or with an opening angle ⁇ .
  • the annular sections 12 facing end portions 1 1 in the circumferential direction both have a length Ii or extend over a circumferential angle ß and are compared to the constant width bi of the subsequent part of the annular body 10 widened radially inwardly and have a radial width b2.
  • the length and width b 2 of the end portions 1 1 is chosen so that a resulting in the rotation due to the missing in the gap area mass of the ring body 10 imbalance is compensated.
  • the circlip 1 or snap ring shown in which the gap-side end portions 1 1 protrude radially on the inner circumference of the ring body 10, while they lie on the outside of the ring body 10 in continuation of the curved peripheral contour of the subsequent portion of the ring body 10, is at one ne corresponding receiving groove (not shown) adapted to the inner circumference of a circular bore.
  • To insert the locking ring 1 is compressed against its elasticity, so that it can be inserted into the bore and then snapped into the receiving groove and then the groove bottom is applied.
  • the circlip 1 is designed so that it deviates in the unloaded free non-use state along its outer circumference relative to a circular shape and is circular in its inserted into the receiving state, where he (except for a permissible tolerance) except in the region of the annular gap 12 all around the groove bottom preferably under tension.
  • the dimensioning of the angle bisector of the gap opening angle symmetrical end portions 11 in their length and radial width b2 is chosen so that the balancing of imbalance (imbalance compensation) is exactly matched to the circular in the installed state contour of the securing ring 1.
  • the annular body 10 of the locking ring 1 has a constant thickness in the region of its gap-side end portions 11 and thus gives an exact location in the receiving groove.
  • An example of a sizing with exact unbalance compensation is at an outer diameter of a locking ring of 192 mm, a thickness of 1, 6 mm and a radial ring width bi of 5 mm and a gap width of 26 mm so that the end portions 11 each have a length U of 28 mm and a radial width of 7.5 mm.
  • These ratios can be chosen according to other diameters of the locking ring.
  • a retaining ring 1 are to be designed for use in the receiving groove of a shaft, the radial broadening of the end portions 11 is selected so that a projection is formed on the outside over the outer circumference of the subsequent portion of the annular body 10, while the round inner circumference is uniform without paragraph over the two end portions 11 extends to the end.

Abstract

L'invention concerne une bague d'arrêt comprenant un corps de bague (10) pouvant être inséré dans une gorge de logement d'un arbre ou d'un alésage et comportant une fente annulaire (12) entre des parties d'extrémité (11) de même longueur côté fente qui sont élargies en direction radiale sur le côté opposé à la gorge de logement lors de l'utilisation par rapport à la partie du corps de bague (10) qui les prolonge, pour compenser un balourd produit par des forces centrifuges différentes lorsque la bague tourne. Une configuration avantageuse pour la fabrication et le fonctionnement réside en ce que le corps de bague (10) comporte jusqu'aux parties d'extrémité (11) une section transversale constante, en et ce que la masse des parties d'extrémité (11) par unité de longueur dans la direction circonférentielle est choisie de telle manière que le balourd provoqué par la fente (12) est compensé.
