Definitions

  • the invention relates to a method for producing Elastomer stators, namely stators that are external have a metallic shell, one of the Elastomer-enclosed cavity at least essentially has the appropriate shape, essentially after Kind of a coiled tube is designed.
  • the invention relates also refer to those stators mentioned in which the Elastomer jacket by injecting an elastomer into a the coat and a core for the design of the Pump cavity containing shape is molded.
  • the invention has for its object the aforementioned Manufacturing process for elastomer stators too simplify without the serviceability of the pumps endanger.
  • Elastomer introduced into the mold in such a way that it only comes into contact with the coat, but not with it a firm connection is established. Accordingly, at the manufacture of stators from an unprepared unprepared shell body, for which there was still it is not even required after its manufacture to be cleaned from a stretched tubular body.
  • the elastomer can be specifically tailored to its requirements be selected in an eccentric screw pump; a Consideration of elastomer compounds that are easy to bind not applicable.
  • the invention is not to special designs of the Tied end portions of the metallic shell. However, it is preferably used in connection with such Coats used, in which the overall short End sections practically cylindrical or slightly are angled or bent radially inwards.
  • the hollow outer part 1 of the shape has a central one Position a core 2, the outside like a two-start thread is formed; a corresponding Shaping also has the inner surface 3 of the Outside part 1.
  • the shape becomes through to the top completed a lid 4, which also to bracket the core 2 serves at the upper end.
  • the stator is first in the mold a double helix, outside of the inner surface 3 of the External part 1 corresponding tube 5 made of steel inserted; this tube 5 is esp. at his Inner surface 5 'untreated, so practically so procure how it is made from a cylindrical tube occurs. Then in the Mold cavity, i.e. in the space between the Inner surface 5 'of the tube 5 and the outer surface of the Kernes 2 rubber injected due to its Composition and its nature neither with the core 2 still with the coiled tube 5 one Binding and therefore not in relation to a Rubber-metal binding is prepared or selected.
  • the stator is after curing or vulcanization completed. He can then easily and without Aftertreatment in the usual way in a pump frame to be built in.
  • Fig. 2 has a position within the Point cavity 6 located, simply coiled Recognize the rotor 7 of the pump. It can also be seen that the pump cavity 6 due to the shape of the tube 5 or of that Stator tube formed by a tube Enclosed rubber layer 8 of approximately the same wall thickness is.
  • This form fit can still according to FIGS. 3 and 4 be reinforced.
  • 3 for the tube 5 one, but preferably both ends a cylindrical End portion 9 provided, the diameter in essentially on the diameter of the largest Bulge of the tube 5 is.
  • the invention does not exclude that in the Production of the coiled tube 5, the ends of which e.g. processed by turning; in any case they are usually not necessary for one Elastomer-metal bond or rubber-metal bond necessary preparations for the adhesive surface, i.e. the Inner surface of the tube 5, since the aforementioned There is no need for a bond.
