Definitions

  • the arrangement includes a spindle rail and a bearing housing.
  • the bearing housing is'attached to the spindle rail and includes a flange having an upper surface above the spindle rail.
  • a spindle top which includes a spindle shaft and a whorl, is rotatably mounted in the bearing housing. The whorl has a lower surface positioned in the vicinity of the upper surface of the flange in spaced relationship thereto.
  • a base-bearing is located within the bearing housing. An end of the spindle shaft is supported in the basebearing. The base-bearing is resiliently supported by a spring so as to provide for axial mobility.
  • FIGZ F161 I SPINDLE ARRANGEMENT BACKGROUND OF THE INVENTION
  • This invention relates generally to a spindle arrangement of spinning machines, twisting machines and the like.
  • the invention relates, more particularly, to a spin dle arrangement having a spindle top which is mounted rotatingly in a bearing housing attachable to one spindle rail of the corresponding machine, the bearing housing including a flange whose upper surface is located above the spindle rail, and where at some distance above this upper surface is found the lower surface of a whorl.
  • Spinning and twisting machines are often equipped with automatic spool (bobbins yarn package or the like) change mechanisms which automatically exchange, for example, the filled-up spools for empty spools after the termination of a draw-off.
  • Such spool mechanisms have elements which effectively grasp the spools, these being moved by an automatically controlled mechanism, in the manner required, for the transport of the spools, for the installation of the spools on the spindle, and for the removal of the spools from the spindle.
  • the forces can be very large during these maneuvers, particularly if all of a considerable number of the full spools on a row of spindles of the particular machine are simultaneously exchanged for empty spools by such a spool change mechanism.
  • the foregoing object, as well as others which are to become apparent from the text below, is accomplished by a spindle arrangement useful in conjunction with spinning machines, twisting machines, and the like.
  • the arrangement includes a spindle rail and a bearing housing.
  • the bearing housing is attached to the spindle rail and includes a flange having an upper surface above the spindle rail.
  • a spindle top which includes a whorl and a spindle shaft, is rotatably mounted in the bearing housing.
  • the whorl has a lower surface positioned in the vicinity of the upper surface of the flange in spaced relationship thereto.
  • a base-bearing, resiliently supported by a resilient member, is located within the bearing housing.
  • An end of the spindle shaft is sup ported in the base-bearing.
  • the resilient member provides for axial mobility of the spindle shaft.
  • the flange on the bearing housing serves as an abutment for the whorl, limits axial mobility of the spindle shaft in the downward direction and protects the base-bearing from damage.
  • the axial mobility which is known per se, of the base-bearing support located within the bearing housing is used to provide axial mobility for the spindle shaft.
  • the base of the spindle shaft of the spindle top is supported by the base-bearing.
  • the flange of the bearing housing serves as an abutment for the whorl thereby limiting the axial mobility of the spindle shaft in the downward direction.
  • a greater than normal axial loading of the spindle top is intercepted because the whorl abuts a flange of the like of the hearing housing mounted on the spindle rail. It is thus impossible to overload the base-bearing which supports the spindle shaft. Neither can the whorl be pressed against the sleeve bearing or the bearing tube which carries the sleeve bearing so that-virtually no danger of damage exists.
  • the spindle top could be loaded with an axial force of 1.5 tons without damage to the spindle. Since such extremely large forces do not occur in practice, the overload protection provided by the present invention is completely reliable.
  • the material of lesser hardness can be disposed in some cases on the lower surface of the whorl, or the whorl itself can be made of such material. In genreal, however, it is more advantageous if at least a region of the flange of the bearing housing which begins at its upper surface consists of a material of lesser hardness.
  • the material of lesser hardness is preferably aluminum, bronze, synthetics, rubber, pressed fiber of the like in the form of a disc. The disc of such material is disposed on the upper surface of the flange.
  • an illustrative embodiment of a spindle arrangement 10 includes a spindle bottom (base) 11 and a spindle top 12 rotatably mounted in the spindle bottom 11.
  • the spindle bottom 11 includes a bearing housing 13 which has an annular flange 14 with a flat upper surface 15.
  • the flange l4 lies on the upper surface of a spindle rail 16 of the particular machine.
  • the bearing sleeve 19, as shown, is a so-called centralizing sleeve, but may be of a number of different conventional constructions, if desired.
  • the spindle top 12 includes a spindle shaft 24 which caries a conventional mounting fixture (not shown) on which the spools or the like can be exchangeably placed. These spools can carry yarn packages which may be wound on the particular machine with which the spindle arrangement of the resent invention is associated.
  • the whorl 25 has an interior cavity 26. Both the region of the bearing housing 13, which extends upwardly from the flange 14, and also the region of the bearing sleeve 19, which extends beyond the bearing housing 13, extend into the cavity 26.
  • the whorl 25 and the length of its interior cavity 26 are chosen so that in the uppermost position of the base-bearing 21, the distance a from the lower frontal surface 27 of the whorl 25 to the upper surface of flange 14 is smaller than the distance b from the upper frontal end surface 29 of the bearing sleeve 19 to the upper, inner, end surface 30 of the interior cavity 26 of whorl 25.
  • the axial mobility of the base-bearing 21, furthermore, is chosen so that the length of the downward leading maximum path of axial motion of the base-bearing 21 from its uppermost position is greater than the distance a between the lower frontal surface 27 of the whorl 25 and the upper surface 15 of the flange 14.
  • the whorl 25 and the flange 14 can be suitable to form the whorl 25 and the flange 14, at least in those regions in which they may touch one another, or materials of differing hardness in order to' reduce or to avoid the occurrence of lateral forces when the whorl 25, during its initial or another along the circumferencial portion of the flange 14.
  • the flange 14 of the bearing housing 13 is injection molded aluminum and it may be directly injection molded to the remaining portion of the bearing housing 13 which normally suitable is made of steel.
  • other suitable materials can be provided, for example aluminum, bronze, synthetic plastic material, rubber, pressed fiber or the like.
  • the whorl 25 can in general suitably be made of steel in the usual manner.
  • the whorl 25 carries a tangential belt or some other drive belt which drives the spindle top 12.
  • the flange 14 instead of making the flange 14 completely of a softer material than the whorl 25, one can also suitably provide that only a region beginning at its upper surface 15, at which the whorl 25 is to abut, be made of such a softer, resilient or elastic material.
  • a disc or a layer of such softer material be inserted or placed on or in the flange 14, as is shown in an example in FIG. 2, where a thin disc 31 made of elastic synthetic material is disposed on the flange 14.
  • the flange 14 in this case can be made of steel or the like or in some cases can be made of a softer material than steel, or it can be made in some other conventional manner.
  • the bearing housing 13 can, in some cases, include one or several other integral projections, a shoulder or the like, which form an abutment or abutments which limit the downward motion of the spindle top 12 either fixedly or somewhat resiliently.
  • the spindle arrangement 10 cannot be overloaded and therefore can no longer be damaged by too great a magnitude of axial forces acting on the spidnle top 12 when anomalous axial loadings occur during the automatic placement of a spool on the spindle top 12 and which without the measures according to the invention, could lead to damage of the spindle bearing.
  • the flange 14, or some other provided abutment, abutments or the like of the bearing housing 13, which limit the downward motion of the spindle top 12 in order to avoid damage of parts of the spindle during the danger or axial overloading of the spindle are effective as abutments for the whorl 25 only in the lowermost position of the spindle top 12 because normally the whorl 25 is always located at some distance above this abutment or abutments so that in its operation it may rotate freely.
  • the danger of axial overloadings occurs only when the spindle top 12 is standing still, i.e., when a spool change is to take place.
  • a spindle arrangement particularly useful in conjunction with spinning machines, twisting machines and the like, comprising, in combination:
  • a bearing housing attached to said spindle rail, said bearing housing including flange means having an upper surface above said spindle rail, which surface serves as an abutment;
  • a spindle top rotatably mounted in said bearing housing, said spindle top including a spindle shaft and a whorl, said whorl having a lower surface positioned in the vicinity of said upper surface of said flange means and spaced therefrom by a given maximum distance;
  • a base-bearing located within said bearing housing, an end of said spindle shaft being supported by said base-bearing;
  • resilient means located within said bearing housing in a space greater in length then said given maximum distance for resiliently supporting said basebearing and allowing downward movement of said spindle shaft and said base-bearing;
  • the flange means on the bearing housing serves as the abutment to limit axial mobility of the spindle shaft in the downward direction against the force of the resilient means to the given maximum distance.
  • said flange means comprises at least one projection extending radially from said bearing housing.
