  • the quick-change bearing unit 197 is advantageously rotatably but releasably secured to the spindle shaft 132 by means of positive and / or non-positive connection.
  • the quick change storage unit 197 may, for. B. pushed onto the spindle shaft 132 in a form-fitting manner and secured against sliding out by means of a screw connection.
  • the bearing housing is opened and the defective quick change bearing unit 197 withdrawn from the spindle shaft 132. Subsequently, a new quick-change bearing unit 197 can be mounted as described above.
  • Fig. 6 also shows a device 200 for limiting the axial displacement of the bearing housing 141 relative to the outer housing 121 and thus to limit the axial load of the fastening means 133.
  • the limiting device consists of projections on the bearing housing 123 or an annular flange, which in a groove-shaped recess 122 on the outer housing 121st are guided.
  • the distances between the upper and lower wall of the recess 122 and the projections 123 are set so that they allow a trouble-free, ie non-contact precession movement, but in the axial direction to ensure a movement limit against both up and down. This will prevent that the elastic fastening means 133 are overstressed by axial Doff mechanism.
  • the above limitation means 200 is not limited to this embodiment, but is applicable to the other embodiments and modifications thereof.
  • the spindle arrangements of the embodiments according to Fig. 2 . 5 and 6 are also applicable to funnel or loop spinning machines.
