  • Such steel rivet cages are known for example from the documents DE 925 203 A and DE 88 16 173 U1 and consist of two identical ring halves made of sheet steel with molded pocket halves and connecting webs arranged therebetween, which are connected to one another by rivets.
  • Such steel rivet cages are primarily characterized by good running properties and low manufacturing costs and are suitable for operating temperatures greater than 130 ° C. and for high speeds.
  • Plastic snap cages on the other hand, consist of a circumferential side ring with pocket webs extending axially away from this on one side, which merge into two elastically flexible pocket claws which are spaced apart from one another through a space, which in pairs form several cage pockets surrounding the balls and are for example from the publications DE 199 37 664 A1 and DE 10 2009 013 978 A1 be known.
  • Such plastic snap cages are mainly manufactured from thermoplastics by injection molding and are distinguished due to good running and sliding properties as well as suitability for operating temperatures from -30 ° to + 130 ° C.
  • the locking elements are formed by means of an extension of every second web half molded Hal ments with locking pawls at the end, which are inserted into the bottom half of each second web and formed as receptacles with locking grooves at the end.
  • the advantage here is that the locking lugs snap into the locking grooves in the radial direction, so that this connection is further strengthened when the centrifugal forces act during bearing operation.
  • the disadvantage is that a bearing cage designed in this way is only suitable for an even number of balls and that the brackets with the snap-in noses are also subjected to tangential loads during operation, and there is therefore a risk of bracket breakage and complete cage failure.
  • the locking elements and the locking receptacles are formed in that the cages fighden are formed at the ends of their web halves with an axial pin and an axial pin receptacle arranged next to the pin.
  • Each pin receptacle of one half of the cage has a radially stretching ring section that extends over the pin when the pin of the other half of the cage is received and thus supports the pin radially outward against the acting centrifugal forces.
  • the disadvantage here is that the axial division plane of the cage halves is arranged exactly at the level of the axial center of the cage pockets and thus precisely at the point of the cage-rolling element contact, so that there is an increased advance and trailing of the balls in the rolling element pockets during operational reasons Cage wear can occur.
  • JP 2007-113 592 A finally discloses a two-part bearing cage for a deep groove ball bearing, which comprises a first cage half and a second cage half which is identical to the first cage half.
  • the cage halves each have an annular base body and a plurality of axially extending cage web sub-segments, the length of which corresponds at least approximately to the width of the bearing cage and the width of which corresponds to about half the width of a complete cage web.
  • the cage web sub-segments are formed with locking elements designed as locking pins, which engage in complementary locking receptacles formed as locking bores in the base body of the other half of the cage, so that when the locking elements of one cage half engage in the locking receptacles of the other half of the cage complete cage bars are formed, between which a large number of cage pockets are arranged to accommodate rolling elements.
  • the invention is therefore based on the object to design a two-part bearing cage in which the plane of division of the two cage halves is arranged outside the center of the cage pockets and the cage halves in a simple injection molding tool without Rework can be produced in such a way that the locking elements and locking receptacles have sufficient stability against breakage in the event of tangential cage loading.

  • the assembly of the cage halves to a complete bearing cage thus takes place in such a way that the cage halves with their cage web sub-segments facing each other are initially offset by a cage pocket in the circumferential direction, so that the cage web sub-segments with the trapezoidal web lugs of a Käfighotf te are arranged exactly opposite the cage web subsegments with the locking lugs of the other half of the cage.

  • the length of the locking grooves in the ring-shaped base bodies of both cage halves in the circumferential direction is greater than the width of the locking lugs on the cage web sub-segments, so that there are free spaces on both sides of the locking lugs through which damage to the locking lugs resulting from tangential loads on the locking lugs Latches are avoided and which allow a Aufwei device of the width tolerances of the latches.
