  • the outer packaging sleeve consists of a cardboard and its elasticity can be produced by a parallel to the longitudinal central axis of the packaging sleeve in this incorporated profiling bar.
  • the production of the outer packaging sleeve of a profiled cardboard has proven to be the cheapest in terms of material and manufacturing costs, but as an alternative material for the outer packaging sleeve and a stretchable plastic is conceivable.
  • a first embodiment of the transport and mounting device designed according to the invention it is according to claim 3, that the outer packaging sleeve has a wave-shaped profiling, in which alternately connects a positive profile wave to a negative profile shaft.
  • the profile shafts always have such a size that the center distance between the individual profile shafts is smaller than the diameter of the rolling bodies, in order thus to ensure that the rolling elements in each case of at least two negative profile shafts of the outer packaging sleeve in the transport and mounting device are kept.
  • the outer packaging sleeve may also have a trapezoidal profiling, in which alternately connects a positive profile trapezoid to a negative trapezoid profile.

  • the transport and mounting device designed according to the invention thus has the advantage over the transport and mounting devices known from the prior art that the rolling element to be filled is sealed by the outer packaging sleeve having a smaller inner diameter than the diameter of the enveloping circle an elastically expandable profile is reliably avoided that individual or even all rolling elements can fall out during transport from the transport and mounting device.
  • the filling of the transport and mounting device with the rolling elements is greatly facilitated by this training and it must be spent in the assembly of the rolling elements no more forces to insert the WälzSystem principles in the bore of the component and thereby strip the outer packaging sleeve can.

  • the elasticity of the outer packaging sleeve 4, during assembly of the rolling bodies 2, 3, does not require any high forces to be applied in order to insert the roller body sets into the bearing location and thereby strip the outer packaging sleeve 4.
  • the outer packaging sleeve 4 consists of a cardboard, wherein the elasticity can be produced by a parallel to the longitudinal center axis of the packaging sleeve 4 in this incorporated profiling 1 1.
  • the profiling 11 of the outer packaging sleeve 4 has a waveform in which a positive profiled shaft 12 alternately adjoins a negative profiled shaft 12, while in FIG shown second embodiment of the transport and mounting device 1 according to the invention, the profiling 1 1 of the outer packaging sleeve 4 is formed with a trapezoidal shape, in which alternately a positive profile trapezoid 13 connects to a negative profile trapezium 13.

Abstract

L'invention porte sur un dispositif de transport et de montage (1) pour un ou plusieurs jeux complets de corps roulants cylindriques (2, 3), qui est essentiellement constitué par un manchon d'emballage extérieur (4) et un manchon d'emballage intérieur (5) disposé coaxialement au premier, entre lesquels sont disposés les corps roulants (2, 3) juxtaposés sur un cercle primitif commun et se touchant sur leurs surfaces périphériques. La cavité (6) du manchon d'emballage intérieur (5) est dans ce cas fermée des deux côtés par des bouchons creux (7, 8) en forme de tasse, qui sont en liaison serrée avec le manchon d'emballage intérieur (5) et qui présentent des rebords marginaux (9, 10) qui débordent au-delà de la paroi extérieure du manchon d'emballage intérieur (5), pour assurer la fixation en position axiale des corps roulants (2, 3). Selon l'invention, dans l'état non garni du dispositif de transport et de montage (1), le manchon d'emballage extérieur (4) présente un diamètre intérieur (DI) plus petit que le diamètre (DH) du cercle enveloppe des corps roulants (2, 3) qu'il s'agit de placer et il possède une élasticité grâce à laquelle ce manchon peut s'élargir lorsque l'on garnit le dispositif de transport et de montage (1) avec les corps roulants (2, 3) pour atteindre le diamètre (DH) du cercle enveloppe des corps roulants (2, 3), en même temps, tous les corps roulants (2, 3) peuvent être immobilisés dans le dispositif de transport et de montage (1) avec une faible force de serrage, et ce dernier dispositif peut être extrait facilement par un côté du palier lors du montage des corps roulants (2, 3).
