Definitions

• the invention is based on a bearing recording according to the preamble of claim 1.
• a bearing receptacle for a spherical bearing is already known from the ⁇ S-? S 5,661,357, which includes the spherical bearing without further aids.
• the bearing holder is in one piece with a housing of an electrical machine.
• the housing is made of plastic.
• a metal housing with such an integrated bearing holder is difficult to manufacture. Often becomes one.
• Bearing plate, which contains the bearing holder, needs as a magnetic Pa-. gleichBankelen-.ent and must therefore be made of metal.
• the bearing receptacle according to the invention with the characterizing feature of claim 1 has the advantage that a bearing in a housing is kept stress-free in a simple manner and does not absorb any axial forces.
• the sleeve is made of copper, aluminum or plastic.
• the bearing can advantageously be a roller bearing or plain bearing.
• the bearing is a slide bearing, it is advantageous if there is an elastic spring element which is used to adjust an axial play of the rotor shaft.
• FIG. 1 shows a first exemplary embodiment of a bearing receptacle designed according to the invention
• FIG. 2 shows a second exemplary embodiment of a bearing receptacle designed according to the invention. Description of the design examples
• FIG. 1 shows a bearing receptacle 1 according to the invention, in which a bearing 5 is arranged.
• the bearing holder 1 is part of a housing 9, which is for example the housing 9 of an electrical machine.
• a rotor shaft 6 is stored in the bearing 5.
• the bearing 5 can be a roller bearing or a plain bearing, e.g. be a spherical bearing.
• a sleeve 23 which consists of a mechanically softer material than the material of the housing 9, i.e. the yield stress of the sleeve material is less than that of the housing material.
• the sleeve material can e.g. B. copper, aluminum or plastic.
• the sleeve width can be chosen larger, smaller or equal to the bearing width.
• the bearing 5 with the sleeve 23 is inserted into a bulge 12 of the housing 9 until a first axial bearing end 20 abuts an axial end 15 of the bulge 12. Then the material ⁇ es Geneaus 9 is plastically deformed from the outside on the housing 9, for example caulked, that material is shifted in the direction of the bulge 12 and a bead 17 engages a second axial bearing end 19 and the permanent deformation is able is to absorb occurring axial loads.
• the sleeve 23 is plastically deformed in this area and holds the bearing 5 in the bearing receptacle 1, ie firmly on the housing 9, and thus forms a bearing holder integrated in the housing 9.
• the material of the housing 9 must be mechanically softer than the material of the bearing 5, because otherwise that Warehouse 5 would deform and could no longer perform its storage functions.
• the plastic deformation can also be done by embossing or rolling.
• FIG. 2 shows a second exemplary embodiment of a bearing receptacle 1 according to the invention.
• the bearing 5 is a plain bearing 5 or a spherical bearing 5.
• the plain bearing 5 is formed in a manner similar to FIG. 1 by the plastic deformation of the housing 9 in the region of the axial bearing end 19 in the bearing holder 1 held.
• the slide bearing can have an axial run-up 25, on which a spring element 27 engages, which minimizes the axial play of the PvOtorwelle 6.
