Definitions

  • the ends of the rolling bearing cage are connected in the assembled state at the point of interruption by a fastener or cohesively with each other.
  • a fastener or cohesively with each other In this way, the mounting of the rolling bearing cage in a groove of an outer ring or inner ring of a roller bearing can be carried out by widening or compressing the rolling bearing cage.
  • the intended interruption point thus serves only for mounting the roller bearing cage already provided with rolling elements in a bearing ring.
  • the object of the invention is therefore to provide a roller bearing cage, which allows a simplified mounting of the rolling elements, with damage to the bearing surfaces and the rolling bearing cage to be avoided during assembly.
  • roller bearing cage in which the side ring is severed at least one point.
  • the severed ends are in each case connected via an adjusting means, preferably a screw connection with each other. By pressing the screw, the diameter of the roller bearing cage can be changed.
  • the roller bearing cage has a stop for limiting the screw opening.
  • the use of a pin for the stop has proven to be particularly useful. By the stop the maximum possible screw opening can be specified. As a result, a too large opening width of the roller bearing cage can be avoided.
  • the rolling bearing cage is in a rolling bearing, which has at least one outboard installed. It has proved to be particularly advantageous if the outer ring of the rolling bearing is provided with a bore in a further developed embodiment. In this hole, an actuator for actuating the screw be introduced. In rolling bearings with outboard rolling bearing cage and inner ring can not easily pivot relative to the outer ring. In order nevertheless to allow a diameter-width adjustment of the roller bearing cage, it is therefore necessary to provide a corresponding access to the screw.
  • the introduced for this purpose in the outer ring of the bearing bore can serve according to a further advantageous embodiment for the introduction of lubricants in the rolling bearing. However, it would also be conceivable for a lubricant bore already present in the outer ring to be used for introducing the actuating tool.
  • FIG. 2 shows a 3D representation of the rolling bearing cage according to the invention, which is installed in a double-row roller bearing;
  • FIG. 2 shows a 3D representation of the rolling bearing cage according to the invention, which is built into a double-row roller bearing.
  • the region having the severed point 05 is shown cut.
  • the illustrated embodiment of the roller bearing cage 01 has a side ring 02. Starting from both side surfaces of the side ring 02, numerous webs 03 extend in the axial direction. Side ring 02 and webs 03 form for receiving rolling elements 04 serving rolling bearing pockets.
  • the roller bearing cage 01 is already filled with rolling elements 04 and is located between the inner and outer ring 08, 09 of the bearing.
  • the introduction of the rolling elements 04 was carried out as described below.
  • the screw 06 was actuated via a suitable actuating element, for example an Allen key. Access to the screw 06 is produced in different ways depending on the type of bearing used.
  • roller bearings without outboard rolling bearing cage 01 and inner ring 08 can be pivoted ozoring 09 in relation to the Au-. In this way, arranged at the severed point 05 screw 06 is accessible from the outside and can be actuated via the actuating element.
  • rolling bearings with outboard for use such a pivoting of roller bearing cage 01 and inner ring 08 does not occur.
  • the bore can also serve for introducing lubricants into the rolling bearing at the same time.

Abstract

La présente invention concerne une cage de roulement (01) comprenant une pluralité de logements destinés à recevoir des corps roulants (04), formés par au moins une bague latérale (02) et une pluralité de brides (03). Les brides (03) s'étendent à partir d'au moins une surface latérale de la bague latérale (02) dans une direction axiale. La bague latérale (02) est selon l'invention sectionnée en au moins un emplacement (05). Les extrémités sectionnées sont reliées entre elles par un élément de réglage (06) de sorte que la valeur du diamètre de la cage de roulement (01) peut être modifiée par actionnement de l'élément de réglage (06).
