Definitions

  • the present invention relates to an axially oscillating centrifuge in which the centrifuge ⁇ drum and the drum centrifuge, the said energy-storing springs also provide j the clamping force acting between the bearings of the centrifuge drum.
  • the arrangement is such that the two oscillatable masses of the system are prevented from performing any undesirable wobbling motion, since the shaft carrying the centrifuge drum is supported in the casing in such a manner as to be movable in an axial direction.
  • an oscillating centrifuge of the type indicated can be further improved by providing for the springs serving to guide the said sleeve member along a straight line also to act as energy-storing springs.
  • the said guide springs which are suitably reinforced so as to enable them to function also as energy-storing springs are made of steel and are therefore less susceptible to high temperatures of the material to be processed than are the rubber storing springs used in the centrifuge described earlier.
  • additional ⁇ adjustable buffers may berprovided for the purpose of regulating the magnitude of the oscillatory movements.
  • FIG. v1 is a schematic longitudinal sectional view of an embodment of an oscillating centrifuge in which the axis of the drum is disposed horizontally, the drum being adapted to oscillate'in an axial direction; this embodiment having separate energy-storing springs;
  • FIG. 2 illustrates a modified embodiment
  • the shaft 1 of the embodiment of FIG. l may carry at one end a V-belt pulley serving to drive the shaft in rotation, and the said shaft carries at its inner end a drum 2 which is rigidly secured thereto, the drum being, for example of conical shape, the wider portion of the drum facing away from the shaft.
  • the casing 3 may be supported from a suitable foundation by springs 4 or may be suspended in the foundation in a Vertical position; the casing carries a plurality of counter-rotating out-of-balance weights 5 serving in a per se known manner -to cause the casing to oscillate in an axial direction.
  • These oscillations are conveniently transmitted by way of resonance, through a plurality of energy-storing :springs 6, to a sleeve member 7 and thence ⁇ to the rotating shaft 1 and lthe drum 2.
  • the sleeve member 7 which is of substantially cylindrical shape has an integrally formed flange 8 which is abutted on both -sides by sets of energy-storing springs 6. Telescoped into the sleeve member 7 are two radial and thrust bearings 9 which are spaced apart to support the shaft 1 in a suitable manner.
  • the two bearings are resiliently preloaded by a force exceeding the peak force produced'by the oscillations of the oscillatable parts; for this purpose, the shaft 1 Vis provided with two integral anges 10 and 11, and a plurality of springs 12 are disposed between the outer race of one of the bearings 9 and an adjustable closure member 13 engagingthe sleeve member 7 and serving to adjust the force applied by the springs 12.
  • the amplitude of the oscillations is limited in the present embodiment by resilient stop members or buffers 23 which co-operate with anges 22 formed integrally with the sleeve member 21 supporting the bearings of the drum shaft.
  • the said buffers 23 may be adjustable so as to permit the amplitude of the oscillations to be regulated.
  • An oscillating centrifuge system comprising a resiliently mounted centrifuge casing, a perforated centrifuge drum in the casing, a drive shaft rigidly supporting the drum and extending axially thereof, drive means connected to said drive shaft, a sleeve member disposed in said casing and surrounding said drive shaft, means on the casing for producing oscillations of the casing in a substantially axial direction of the drive shaft, bearing means mounted in the sleeve member and rotatably supporting said drive shaft, said casing having opposing inwardly extending wall portions extending adjacent the opposite ends of the sleeve member, cooperating means on said sleeve member and opposing wall portions located between said wall portions for yieldably limiting axial movement of the sleeve member relative to said wall portions, and a plurality of leaf springs each extending in a plane radial relative to the drive shaft and anchored externally to each wall portion and to the adjacent end of said sleeve member, said leaf springs dening resilient links to
