Definitions

  • the invention relates to a rotor of a centrifugal separator, the rotor having a central shaft, on which a stack of plates consisting of a plurality of plates is arranged to be axially displaceable, a stacking base being arranged on the shaft under the stack of plates, a stacking attachment being axially displaceable on the stack of plates Shaft is arranged and the rotor has a compression spring surrounding the shaft, the first end of which is supported on the stack and compressing the stack of plates on the stacking attachment.
  • a rotor of the type mentioned is from WO 2009/010248 A2 known.
  • the second end of the compression spring presses on the top of the stacking attachment. So that the compression spring can be arranged on the shaft, the shaft must protrude beyond the stacking attachment by at least the tensioned length of the compression spring. Disadvantageously, this part of the shaft is not available for receiving plates from the stack of plates.
  • the object of the present invention is therefore to create a rotor of the type mentioned at the outset which, with the same external size, has a larger number of plates in the stack of plates without the plates having to be changed for this purpose.
  • a sleeve-shaped extension which projects into the stack of plates and surrounds the shaft at a distance is arranged on the stack attachment, such that the compression spring at least over the greater part of its axial length within the Extension is located and that a support surface for the second, stack-side end of the compression spring is arranged on a bottom of the extension.
  • the stacking attachment and the sleeve-shaped extension are preferably formed in one piece with one another.
  • the stacking attachment and the sleeve-shaped extension can also be designed as two interconnected individual parts.
  • the shaft consists of metal and is surrounded by a torsion-resistant jacket made of plastic, the jacket on its outer circumference an engagement contour for a torsion-proof, axially displaceable engagement with a counter-engagement contour on the inner circumference of the plates of the stack of plates.
  • the metallic shaft provides the necessary stability for the rotor.
  • the contours necessary for the interaction of the different parts of the rotor can advantageously be formed simply on the jacket, since this is made of easily moldable plastic, for. B. thermoplastic or thermosetting plastic.
  • the outer circumference of the casing be formed with teeth made of teeth running in the axial direction of the shaft, and that the plates of the stack of plates be designed with suitable counter-toothing on their inner circumference. These contours can be easily manufactured and reliably provide the desired torsion-proof but axially movable engagement between the casing and the stack of plates.
  • the jacket has an engagement contour for a torsion-proof, axially displaceable engagement with a counter-engagement contour on the sleeve-shaped extension of the stack attachment at its end region facing the stack attachment. This achieves an arrangement of the stacking attachment of the rotor which is non-rotatable relative to the casing but is axially displaceable.
  • the jacket in its end region facing the stacking attachment is formed with teeth made of teeth running in the axial direction of the shaft, and that the sleeve-shaped extension of the stacking attachment is designed with suitable counter-teeth.
  • the sleeve-shaped extension of the stacking attachment has an engagement contour on its outer circumference for a torsion-proof, axially displaceable engagement with a counter-engagement contour on Has inner circumference of the plate of the plate stack.
  • the engagement contours provided for the plates on the extension of the stacking attachment and on the jacket are expediently carried out identically and continuously next to one another.
  • the invention further proposes that the jacket is molded onto the shaft. This also ensures in a safe manner that the jacket sits on the shaft in a torsion-proof manner.
  • the stacking base and the casing are expediently made in one piece.
  • the stacking base is thus arranged in a simple and secure manner relative to the shaft in a manner fixed against rotation and axially fixed.
  • the compression spring is supported with its first end on the shaft, which support can be direct or indirect. Is preferred the compression spring with its first end facing away from the stacking attachment is supported on a radially projecting collar of the shaft or on an axially fixed ring, such as a snap ring, which is used to achieve a very compact design.
  • a further development of the rotor according to the invention is characterized in that an intermediate body is arranged between the first end of the compression spring on the one hand and the collar or ring on the other hand, and that the stacking attachment has an axially outer collar which surrounds the intermediate body radially on the outside and which can be moved axially relative to the intermediate body in a sealing manner is. This prevents undesirable incorrect flows of the fluid medium to be cleaned flowing through the rotor through the sleeve-shaped extension and the stacking attachment out of the rotor.
  • the shaft viewed in its axial direction, consists of two shaft parts, a first shaft part serving to rotate the rotor being made of metal, a second shaft part carrying the plate stack consisting of plastic and with the first shaft part is non-rotatably and axially fixed and the second shaft part has on its outer circumference an engagement contour for a torsion-proof, axially displaceable engagement with a counter-engagement contour on the inner circumference of the plate of the plate stack.
  • the second shaft part be formed on its outer circumference with teeth made in the axial direction of the second shaft part and that the plates of the plate stack should be formed on their inner circumference are designed with a suitable counter-toothing.
  • the second shaft part has an engagement contour for a torsion-proof, axially displaceable engagement with a counter-engagement contour on the sleeve-shaped at its end region facing the stacking attachment Has extension of the stacking attachment.
  • the plate stack can thus be pressed together in the desired manner via the sleeve-shaped extension of the stacking attachment, undesired twisting of the stacking attachment with the extension relative to the second shaft part being avoided.
  • a further embodiment in this regard provides that the second shaft part in its end region facing the stacking attachment is formed with teeth made of teeth running in the axial direction of the shaft and that the sleeve-shaped extension of the stacking attachment is designed with suitable counter-teeth.
  • the sleeve-shaped extension of the stacking attachment can also be used for the arrangement of plates of the stack of plates, it is proposed that the sleeve-shaped extension of the stacking attachment have an engagement contour on its outer circumference for a torsion-proof, axially displaceable engagement with a counter-engagement contour on the inside circumference of the plate of the plate stack having.
  • the engagement contours on the extension and on the second shaft part for the plates are preferably identical to one another and continuously adjoining one another. This means that the same plates can be used for the plate stack within the rotor, regardless of whether a plate is arranged on the extension or on the second shaft part.
  • the second shaft part is expediently injection molded onto the first shaft part.
  • the stacking base and the second shaft part are preferably made in one piece with one another.

The second, lower end 52 of the compression spring 5 is supported on a support surface 45, which is formed by the top of the bottom of the extension 41.
