Definitions

  • This invention relates to lifting and lowering motion for the spindle or ring rail of ring spinning or ring twisting frames.
  • the object of the present invention is to eliminate these drawbacks and to provide a lifting and lowering motion for spindle and ring rails respectively which ensures, with a minimum of power required, a smooth running even in the event of there being some small amount of play between the various machine parts.
  • the threaded nut is, therefore, housed in a lifter slide, each part being independently guided on the threaded shaft. This arrangement protects the out from the detrimental effects of a rigid guide in the rail, as it permits some adjustment to any displacements of the parts relative to each other, such as are likely to occur in actual service through influence of heat, dust and wear.
  • connection between the lifter slide and the nut is established by means of a ball bearing which represents another feature of the invention and permits a compensation for any variations in the load resting thereon or any negligible dimensional changes in the parts moving one upon the other.
  • the guide of the lifter slide and nut is rendered particularly advantageous if the threaded shaft is made with a square thread.
  • the drive of the lifter nut is preferably arranged and supported so as to counteract the tilting moment arising when lifting the load carried by the nut.
  • Figure l is a cross-section through the lifting and lowering motion for the spindle rail of a ring spinning machine.
  • Figure 2 is a cross-section through the lifting and lowering motion for double-sided spindle rails of a ring spinning machine.
  • the not 2 is housed in the lifter slide 5 carrying the spindle rail 7 secured to a bracket 6.
  • the lifter slide 5 has guiding sleeves 8 and 9 respectively which are located above and below the nut 2 and tightly bear against the threaded shaft 1. In a sense the nut 2 is supported in the lifter slide 5 in a floating manner, that to say in such 'a way that it is exclusively guided 'by the shaft l and the thread It respectively, but not by th e lifte'rslide proper.
  • the lifting and lowering motion in accordance with the invention it is possible to equip spinning and twisting machines with movable ring and spindle rails of great length which can be moved from a single source of power through the continuous shaft 3 without any risk of jamming.
  • the principle of the invention is analogously applicable to other devices of textile machines effecting an up and down motion, for example movable guide rods or drawing frames.
  • the invention is not restricted in its application to ring spinning and ring twisting machines, but can also be applied to other types of machine, such as slubbing and roving frames, flyer or cap spinning frames and other systems.
  • An arrangement for lifting and lowering the spindle or ring rail of spinning or twisting frames which comprises in combination, a reciprocable lifter slide having a unilateral extension in horizontal direction for supporting spindles and being provided with two spaced cylindrical guiding surfaces coaxially arranged with regard to each other, a substantially vertical shaft having a threaded portion and being in sliding engagement with said spaced guiding surfaces, said shaft being secured against rotation and reciprocation, nut means engaging said threaded portion and being arranged between said spaced guiding surfaces in spaced relationship thereto, driving means "ice arranged within said lifter slide and operatively engaging said nut means for rotating the same, said nut means being guided by said threaded portion independently of said lifter slide, and anti-friction bearing means interposed between and having opposite surfaces engaged by said lifter slide and said nut means respectively, said driving means and said nut means engaging each other by gear means integral therewith and adapted to support said nut means from below when driving said nut means for lifting said lifter slide, to thereby at least partially counteract the
  • An arrangement for lifting and lowering the spindle or ring rail of spinning or twisting frames which comprises in combination, a reciprocable lifter slide provided with two spaced guiding surfaces, a substantially verticai shaft secured against rotation, said shaft having spaced surface portions in sliding engagement with said spaced guiding surfaces and being provided with a threaded portion,
  • rotatable means threadedly engaging said threaded portion and being spaced from'the adjacent wall portions of said slide, and anti-friction bearing means interposed between and engaging said lifter slide and said rotatable means respectively while allowing the axis of rotation of said rotatable means to vary' its position slightly with regard to the longitudinal axis of said shaft.
