ABSTRACT:
One end of the housing for a spinning turbine is closed by a cover adjacent to the spinning cup mouth, which cover is connected with sliver-supply and yarn drawoff apparatus. The other housing end portion encircles a sleeve having bearings for the spinning cup shaft. Such shaft may be connected to drive means such as a belt or a commutatorless direct current motor, which drive means can be quickly disconnected. The sleeve-encircling housing portion includes quickly-releasable means for releasing the bearing sleeve for removal either alone or with attached drive means, and for replacement by a substitute bearing unit. The housing may have a longitudinal slit through a portion of its wall and cooperating lugs on each side of the slit for receiving nut and bolt means to clamp the split housing around the bearing sleeve. Alternatively, a set screw extends through the housing wall and bears on the sleeve to prevent sleeve movement. The sleeve may have a flange adjacent to the open housing end engageable by a pair of swingable leaf spring clips pivoted on the housing to draw the flange toward the housing. A split ring bushing may be interposed between the sleeve and the housing, and may include a collar for mounting the electronic control box for a motor.
