  • the invention relates to a thin-section bearing with a very small cross section with respect to the Lager ⁇ diameter with two bearing rings, between which rolling on corresponding raceways rolling elements. Moreover, the invention relates to a method for producing a thin-film bearing.
  • Such thin-ring bearings in which, in contrast to standard Wälzlagerrei ⁇ hen the cross section with the bearing diameter does not or only slightly increases, there are as four-point bearings, deep groove ball bearings and angular contact ball bearings in a bearing diameter range between 25 and 1000 mm.
  • Main fields of application are handling devices, industrial robots, textile and printing presses, medical, optical and optronic devices, aerospace.
  • the advantages of such generic Dünnringlagern are a low mass, low torque and the ability to create spatial and weight-saving construction, which have a high rigidity and running accuracy.
  • Such Dünnringlager are described, for example, on page 10 of su ⁇ book "The Wälzlagerpraxis", Manual for the calculation and design of bearings, united specialist publisher GmbH, Mainz 1995.
  • the invention is therefore based on the object to provide a new type of Dünnringicalz ⁇ camps, which can be manufactured in particular cost and have a low backlash.
  • this object is achieved according to the characterizing part of claim 1 in conjunction with the preamble in that the bearing rings are produced by a non-cutting shaping process and in that one of the bearing rings has a raceway which in at least one peripheral portion has a circular shape deviating elastically yielding track curvature such that at least one of the rolling elements between the raceway curvature and this opposite track is radially biased.
  • An advantage of the thin-section bearing according to the invention is its simple manufacture by chipless technology. This term is to be interpreted broadly in the sense of the invention and is intended to include all the non-cutting process known to the person skilled in the art.
  • the thin-ring bearings produced in this way do not require subsequent machining of the bearing rings, since the bearing tolerances are compensated by the shape of the outer or inner ring.
  • Another advantage is the possible adjustment of the backlash, which has a positive effect on the formation of noise in particular.
  • a further advantage lies in the fact that the bearing rings produced without cutting have a smaller radial space compared with the bearing rings produced by machining, so that the saving of installation space is possible once again.
  • Ante is the main variant, since in almost all cases it is important to keep the part to be stored free of play.
  • the Dünn ⁇ ring bearing should be as a deep groove ball bearing, an angular contact ball bearings or as a Vierige ⁇ ball bearings.
  • the respective bearing variant depends on the predetermined installation case, which determines the special requirements for the bearing type.
  • the deviating from the circular shape elastically compliant raceway curvature is formed by an inserted in a groove of a bearing ring elastic spring element, spieltagen, by a resilient ring.
  • a wire rolling bearing has arisen, which enables simple manufacture of the bearing rings. These then do not need to be subjected to expensive curing processes, for example.
  • the resilient rings which are placed in the appropriate recess of the bearing rings, consist of high quality spring steel wires and are blown up. The distance between the wire ends ensures that the wire rings fit well and can also expand freely in the event of temperature fluctuations.

  • Direction offset areas may be formed, which are designed with Befesti ⁇ supply holes.
  • the Lager ⁇ outer ring should be formed from a profiled tape that is cut to length and rounded in accordance with the desired later bearing diameter, be ⁇ before it is verbun ⁇ at its abutting ends by a weld.
  • the bearing ring is produced in a particularly simple manner.
  • the thin-section bearing should be used to support a fixed inside of a steering wheel of a motor vehicle fixed airbags, the steering wheel with a steering shaft is rotatably ver ⁇ connected, which is received via two spaced rolling bearings in a Lenk ⁇ tube ,

Abstract

La présente invention concerne un palier annulaire mince comprenant une très petite section transversale par rapport au diamètre de palier, avec deux bagues de palier entre lesquelles roulent des corps de roulement sur des voies de roulements associées. Cette invention est caractérisée en ce que les bagues de palier (12, 13, 17, 18, 23, 24) sont produites grâce à un processus d'usinage sans enlèvement de copeaux et en ce qu'une des bagues de palier (12, 13, 17, 18, 23, 24) comprend une voie de roulement (12.1, 13.1, 17.1, 18.1, 23.1, 24.1) qui présente sur au moins une section périphérique une courbure de voie de roulement (13.2, 21.1) pouvant se déformer de manière élastique en s'écartant de sa forme circulaire, de façon qu'au moins un des corps de roulement (15, 20, 26) soit précontraint en direction radiale, entre la courbure de la voie de roulement et la voie de roulement opposée à celle-ci (12.1, 17.1, 23.1). Le palier selon cette invention présente à la fois l'avantage de pouvoir être produit de manière très simple et de ne présenter aucun jeu.
