Definitions

  • the invention relates to an electric linear drive for generating rectilinear movements along a predetermined axis of movement.
  • a linear drive which is provided with a stator assembly (secondary part) and a rotor assembly (primary part), which are movable relative to each other.
  • the stator assembly includes a U-shaped housing having two parallel legs connected together by a connecting leg. Magnets for forming a magnetic field, which form the stator assembly, are respectively provided on the two parallel aligned limbs.
  • the runner is provided with at least one ironless winding, which lies in a gap between the two legs. none of the housing is located.
  • the rotor has a drive-side extension for attachment to a load to be moved.
  • the invention is therefore an object of the invention to provide an electric linear motor, the same dynamic properties or with the same space allows correspondingly higher driving forces with a small volume.
  • the rotor assembly with a band-shaped and deflectable rotor and a stator assembly having at least one main body with a plurality of bobbins, which are aligned to generate a direction of movement along a predetermined axis of movement of the rotor to the base body and with at least two deflections a deflection device, which are associated with the base body, so that at least a first overlap region between the rotor and the base body is formed, is allowed during the traversing movement of acting on a load coupling element remains a constant length of the overlap region, so that a permanently acting area- che is present for the generation of the drive movement of the rotor.
  • a further preferred embodiment of the linear drive provides that the rotor is guided by the deflection at least partially along the base body and is transferred into a further overlap region by the direction of movement of the rotor is opposite to the first overlap region.
  • the rotor can be effected, for example, that in the case of a plate-shaped main body, a first overlapping region which is formed along one end face can also be formed on the opposite end face.
  • the permanently acting surface is doubled to generate a driving force on the rotor. This allows a further reduction of the installation space. Alternatively, an increase in the driving force can be achieved with the same space.
  • the rotor has a plurality of spaced-apart permanent magnets, which are inserted or integrated. These can be introduced during the manufacturing process. Likewise, the permanent magnets can be subsequently arranged by an adhesive, Klemmoder locking connection or the like on the rotor.
  • the rotor formed as a link chain or as a link belt is, in which two adjacent chain links are pivotally connected together by a bearing axis.
  • This arrangement allows a simple adaptation of the rotor to the length of the base body or the distance of at least two deflection devices to each other.
  • the design of a link chain is a modular structure of a band with two ends or an endless belt created. Such a runner can work both on the train principle and on the push principle.
  • the chain links of the link chain are arranged without play to each other.
  • preloaded bearings can be used in the event that the chain links of the link chain operate on the train principle. This is intended to provide as exact a control as possible in the event of a change of direction in the direction of movement in order to drive a load.
  • At least one guide element is preferably provided, which acts on at least one guide and, for example, endless belt or chain link leads at a defined distance to the main body of the stator assembly.
  • This defined distance is decisive for inducing a driving force in the rotor assembly as a function of the bobbin and the materials used for the rotor and / or the permanent magnet optionally arranged thereon and can be kept constant by the arrangement of the guide elements along a drive path.
  • the guide of the guide elements is preferably arranged on the at least one main body of the stator assembly.
  • this guide is designed as a running or sliding surface.
  • a low-friction guidance can be achieved, which counteracts only slightly the maximum drive force or the force for moving a load.
  • the at least one guide element is designed as a roller or plain bearings.
  • the guide elements are preferably adapted to the guide, so that correspondingly low-friction pairings are selected.
  • the guide element may be formed as a roller bearing, which rolls on a tread.
  • plain bearings can be provided.
  • the guide element which is designed, for example, as a roller or roller bearing, is preferably fastened to the bearing axis, as a result of which a component-reduced arrangement is provided.
  • a further preferred embodiment of the invention provides that the rotor, which is formed of a polymer or rubber material and is driven by the thrust principle, is provided in a preferably circumferential guide, wherein the guide at least between the base body and a stator surrounding the body portion is trained.
  • the guide is arranged in a housing, wherein the base body and the stator are part of this housing, so that a circumferential guide is given.
  • provision is made in particular for both the bobbins in the base body and in the stator section to be provided in the straight-line sections of the guide.
  • This arrangement has the advantage that a simple integration of permanent magnets in the rotor is made possible and at the same time a precise thrust drive can be performed.
  • such runners are made of polymer or rubber material with reinforcements by fiber inserts, steel inserts, fabric, steel tape inserts or the like.
  • the drive path for producing a driving force for the rotor 19 extends over the entire length of the base body 14 in the movement axis of the rotor 19 or through the overlapping region 42 formed thereby. Consequently, in a relatively small-sized unit still a large drive surface can be achieved in the rotor 19, in particular, since on an upper and underside of the base body 14, the formation of an overlap region 42 for generating the driving force is made possible.
  • the overlapping region 42 may also be formed only on the top or bottom of the main body 14.
