Definitions

  • the invention relates to a rolling bearing assembly with an annular needle sleeve, whose inner surface forms a raceway for rolling elements, which are designed as bearing needles and arranged in the circumferential direction at intervals in a row in a cage which is inserted into the needle sleeve and surrounds a shaft on the lateral surface of which Storage needles are supported rollable, wherein the needle sleeve in a receiving space, for. B. a hole of a housing is inserted appropriately.
  • a plurality of serrations or ribs is arranged on the lateral surface of the outer ring.
  • the expansive force of the outer ring causes the serrations to be pressed outwardly against the inner surface of the wall opening or recess in which the outer ring is located. This buries the serrations in the material of the wall. In this way, the outer ring is held axially in the wall.
  • the invention has for its object to provide a bearing assembly in which the inserted into a receiving space of a housing needle sleeve is secured in a simple manner against axial detachment from the housing.
  • a radially projecting barb is arranged on the needle sleeve at at least one peripheral point of its outer surface, which is snapped into a housing recess open to the receiving space as a result of elastic sleeve deformation after insertion of the needle sleeve into the housing , It is particularly cost effective if the needle sleeve is formed only with a single barb and the open housing recess is formed in the form of a circumferential groove in the receiving space of the needle sleeve.
  • the needle sleeve may be a chipless produced component, for example, a sheet metal part made of steel. It can be made with the barb as a one-piece component in a drawing process, by which the barb is formed on the needle sleeve.
  • the snap-action function as axial securing of the needle sleeve reduces costs and simplifies the assembly process. An additional locking ring is no longer necessary in this case.
  • FIG. 1 shows a detail of a bearing assembly in a housing with a shaft and a needle sleeve, in an axial section;
  • FIG. 2 shows an enlarged detail of the needle sleeve in the region of an integrally formed barb opposite FIG. 1;
  • FIG. 3 shows an axial section through a needle sleeve with inserted cage
  • FIG. 4 shows an enlarged detail of the needle sleeve in the region of an integrally formed barb according to arrow IV in FIG. 3;
  • FIG. 5 shows a detail of an end view of the needle sleeve according to arrow V in Figure 4.
  • a needle sleeve 1 in the form of a sheet-metal component produced without cutting contains a cage 2 with inserts therein, designed as bearing needles 3
  • the needle sleeve 1 is axially in a receiving space 4 of a Ge housing 5 fitting inserted.
  • the receiving space 4 is arranged in the housing 5 in the form of a bore.
  • a shaft 6 is rotatably supported by means of the needle sleeve 1. This is coaxially surrounded by the needle sleeve 1, wherein the bearing needles 3 are supported both on the lateral surface 7 of the shaft 6 and on the inner surface of the needle sleeve 1, which acts as a raceway 8, unrolling.
  • a radially projecting barb 9 is formed on the needle sleeve 1 at a peripheral location. This is formed during the manufacture of the needle sleeve 1 by a pulling method on the needle sleeve 1, so that the needle sleeve 1 forms a one-piece component with the barb 9.
  • a housing recess 10 designed as a circumferential groove is arranged in the housing 5, which extends from the receiving space 4.
  • the barbs 9 snap into the housing recess 10, whereby in the region of the barb 9 an elastic deformation of the needle sleeve 1 takes place.
  • the needle sleeve 1 is secured against axial movement out of the exception space 4 of the housing 5.
  • the barb 9 is located in the region of the left-hand end face of the needle sleeve 1.
  • a ring flange 11 of the housing 5 is located in the receiving space 4, which likewise limits an axial displacement of the needle sleeve 1.

Abstract

L'invention concerne un ensemble palier à roulement présentant une douille à aiguilles (1) en forme d'anneau, dont la surface intérieure forme un chemin de roulement (8) pour des corps de roulement conçus sous la forme d'aiguilles de roulement (3) et disposés à une certaine distance les uns derrière les autres dans le sens de la périphérie à l'intérieur d'une cage (2) qui est emboîtée dans la douille à aiguilles (1) et entoure un arbre (6) sur la surface extérieure (7) duquel sont soutenues les aiguilles de roulement (3) de manière à pouvoir rouler. La douille à aiguilles (1) est emboîtée de manière ajustée dans un espace de réception (4), par exemple un trou de boîtier (5). Selon l'invention, la douille à aiguilles (1) présente un ardillon (9) faisant saillie radialement en au moins un point périphérique de sa surface extérieure. Une fois la douille à aiguilles (1) emboîtée dans le boîtier (5), ledit ardillon entre par encliquetage dans un évidement de boîtier (10) ouvert sur l'espace de réception (4) suite à la déformation élastique de la douille.
