Definitions

  • the invention is based on a bearing recording according to the preamble of claim 1.
  • a bearing holder for a spherical bearing which comprises the spherical bearing without further aids.
  • the bearing holder is in one piece with an outer housing of an electrical machine.
  • the housing is made of plastic.
  • An outer housing made of metal with such an integrated bearing holder is difficult to manufacture.
  • a bearing plate that contains the bearing holder is often required as a magnetic yoke element and must therefore be made of metal.
  • EP 703 655 AI shows a bearing holder for a spherical bearing, which comprises the spherical bearing, the bearing holder in a further component of an electrical Motors is plugged in.
  • the bearing mount also has no axial run-up.
  • the FR 78 22850 AI shows a spherical bearing that is held in a bearing seat by a locking ring. This increases the number of parts to be assembled.
  • DE 195 13 970 AI shows a plain bearing, which encloses a free end of a rotor shaft, and on which a spring is integrated, which reduces the axial play of the rotor shaft.
  • the plain bearing is not held in its axial position by a bearing seat.
  • the bearing holder according to the invention with the characterizing features of claim 1 has the advantage over the fact that a bearing holder can be integrated into a housing in a simple manner.
  • the bearing receptacle has an elastic spring element which serves to set an axial play of the rotor shaft.
  • FIG. 1 shows a first exemplary embodiment of a bearing receptacle designed according to the invention
  • FIGS. 2a, b show a second exemplary embodiment of a bearing receptacle designed as such and in the installed state.
  • Figure 1 shows a bearing holder 1 according to the invention, in which a spherical bearing 5 is arranged.
  • the bearing holder 1 is for example made of plastic, but it can also be made of metal or
  • a rotor shaft 6 is supported in the spherical bearing 5.
  • the bearing holder 1 engages around the spherical bearing 5 so that the spherical bearing 5 is held in the bearing holder 1 in a form-fitting manner.
  • Spherical bearing 5 is integral with the bearing holder 1, e.g. made in one piece in a plastic injection molding process.
  • the bearing holder 1 has an axial run-up 8, against which a free end of the rotor shaft 6 bears.
  • Housing 9 must fit.
  • the axial run-up 8 is carried out integrally with the bearing seat 1.
  • the housing 9 is, for example, the housing of an electrical machine, which includes a stator 11 and has a rotor 13 with a central axis 14.
  • the housing 9 is made of metal, for example, and serves as a magnetic yoke element for the stator 11.
  • the bearing receptacle 1 has two sliding surfaces 18 which run towards one another at an obtuse angle, on which the spherical bearing 5 is supported on its circumference and can thus be pivoted with respect to the central axis 14.
  • the invention is not limited to spherical bearing 5, but also for other plain bearings with an integrated bearing holder and axial run-up.
  • Figure 2a shows a bearing holder 1 according to the invention, with an elastic spring element 15 which is arranged on the bearing holder 1, facing away from the spherical bearing 5.
  • the elastic spring element 15 can be in one piece with the bearing receptacle 1 or also in two parts if the elastic spring element 15 is made of a different material, e.g. Rubber is made.
  • the elastic spring element 15 can also be designed in the form of a spiral spring or leaf spring.
  • the bearing holder 1 has at least one projection 7, which in this exemplary embodiment is designed as a clip hook and comprises the spherical bearing 5.
  • the bearing holder 1 according to FIG. 2a is again inserted into the holder 10 of the housing 9, as shown in FIG. 2b.
  • a free end 17 of the elastic spring element 15 abuts a housing base 20 of the housing 9 in the receptacle 10 and thus exerts a spring force in the axial direction, ie parallel to the central axis 14, against the free one End of the rotor shaft 6.
  • the axial play of the rotor shaft 6 is thereby reduced.

Abstract

Selon l'état de la technique, un logement de palier en forme de calotte qui présente une attache de palier intégrée et un segment axial destiné à un arbre rotor, ne peut pas être inséré dans un boîtier. Selon l'invention, un logement de palier (1) peut être inséré dans un boîtier de telle façon que ce boîtier (9) puisse également être conçu en métal, constituant ainsi un élément court-circuit magnétique d'une machine électrique.
