Definitions

  • the entire driving motor usually has to be suspended in such a way as to permit it to oscillate, whence it follows that if the basket or the spindle is caused to swing owing to a want of balance, the non-rotating parts such as the stator, bearings and the like, must also participate in this motion, which-results in preventing the full centrifugal action from being obtained. In consequence, it is virtually impossible to run the machine entirely without jarring.
  • the object of my invention is to produce an electrically-drivem centrifugal machine in which these objections areovercome, two forms of such a machine being illustrated in vertical section in Figures 1 and 2 of the accompanying drawing.
  • T represents the centrifugal basket which is mounted in and fastened to the supporter K, the latter being fitted with the laminated iromcore R of the rotor, and with the squirrel-cage winding and the bars A.
  • the spindle N is mounted at its lower end in a ball-bearing which may be of the well-known SKF type and which is supported by a case G.
  • a plate P Connected with the case G is a plate P which carries the stator core S in the grooves of which the windings W are inserted. 4
  • stator and the rotor are spherically turned, so that in case the spindle swings laterally in any. direction no contact can take place.
  • springs F are placed in the, frame or case G which exert a slight supporting action on the spindle so as to maintain it in its central position.
  • Fig.2 shows an analogous device in which, however, the basket and rotor are connected by a short spindle. The whole is so arranged that the center of gravity lies beneath the supporting bearing, wherefore the supporting springs F maybe omitted.
  • Mechanism for rotating a relatively-large body at high speed involving a spindle'to which such body is'directly afiixed, a supporting frame, a ball-bearing wherein the spindle is mounted located in said frame and providing a center of.
  • said motor comprising a rotor fastened immediately to the spindle and a stator fastened immediately to the frame, the rotor and stator constituting companion parts, one of which has a convex face and the other a concave face to conformably receive said convex face, the
  • center of curvature of both faces being the aforesaid center of oscillation of the spindle, whereby said faces are constantly maintained in spaced, parallel relation throughout their entire extent during the tilting move.- ments of the, spindle.
