Definitions

  • the number of revolutions of the coiler gear is deermined by the diameter of a circle along which the sliver is laid down during one revolution of the coiler gear and the speed of the sliver. Therefore, when the coiling diameter is too small, or when the angular velocity is too fast, diiiiculties arise with the bearings employed, the problems increasing with the running speed.
  • a mechanism for low-speed operation a mechanism is used in which a circular projection is provided on the bottom surface of the coiler gear, and a circular groove receiving said projection is provided on a coilergear-supporting plate for providing a sliding support therebetween.
  • a thrust bearing may oey interposed Vbetween the coiler gear and its supporting plate.
  • three types of mechanism have been developed.
  • three or four roller units which are carried by ball bearings on a supporting plate, are arranged at spaced points along the outer periphery of the plate so as to mount the coiler gear in a floating state with respect to the supporting plate at three or four locations via said rollers.
  • a particularly large ball bearing is utilized, the bearing having its inner race iiXed to the coiler gear and its outer race to the supporting plate.
  • the coiler gear is supported at its outer periphery so that the running speed of its bearing elements becomes veryhigh which also imposes certain practical limitation.
  • a suitable supporting assembly such as a ball bearing ⁇ is arranged at a reduced-diameter top portion of the coiler gear instead of supporting the coiler gear at its bottom portion where its diameter is maximum.
  • a coiler gear can be generally assumed to be conical, it is able to utilize a supporting surface of relatively small diameter when the coiler gear is supported at its top portion. Moreover, the necessary number of revolutions of the coiler gear itself ,may be the Same as those in the above mentioned two mechanisms.l This permits considerable reduction in the running speed of the supporting member. Furthermore, by this arrangement, also, the bottom of the coiler gear is maintained in a oating state with respect to the supporting plate.
  • able driving means such as a rope or lil-:e iiexible element. While these arrangements are utilized principally in the iirst mentioned mechanism, gear teeth are arranged at the top portion of the coiler gear in the last mentioned mecha-v nism. "fhus, all of these driving arrangements are disposed near the supporting elements.
  • the coiler gear since the coiler gear has a conguration which is quite unbalanced for rotation, it has a tendency to gyrate under influence of its centrifugal force. Notwithstanding these two inevitable states of forces, the coiler gear is supported by a single bearing means in these said prior arrangements.
  • the feature of this invention resides in separating into tWo parts, i.e., a top part and a bottom part or pan, a coiler tube gear which is usually made as an integral unit and to provide separate bearings tothe respective parts.
  • the upper bearing functions to support the thrust caused by, gear drive but is substantially free from the effect of unbalance of the coiler gear itself, and this effect of unbalance may be supported by the bearing device in the bottom part.
  • the upper bearing is arranged to support the thrust caused by gear drive as well as the effect of unbalance in the coiler tube portion.
  • coiler tube is relatively small, the effect of unbalance is relatively small, and this effect can be further reduced by utilizing a suitable counter Weight.
  • the bottom bearing device must support the bottom pan body having relatively large mass, but there is no serious problem because the pan can be constructed to have a shape easy to balance.
  • the bottom part or pan is required not only to support relatively massive coiler gear but also to withstand large upward force acting upon its lower surface caused by groups of slivers lfirmly compacted in a sliver can.
  • the force acting upon the lower bearing device is considerably larger than that acting upon the upper bearing device.

  • FIG. 3 is a side elevational view, partly in section, of

  • FIG. 7V is a side elevational View, partly in section, of the bottom part of -the modified mechanism for explaining its method of support.
  • a sliver is inserted into an inlet opening- A at the topof Va coiler-gear mechanism and is discharged to drop in to a sliver can, not shown, which is arranged beneath the mechanism, throughV an inclined guide passage B and a discharge opening C
  • the sliver is laid in a circular Y manner as the discharge opening sweeps along a circular locus upon the rotation of the assembly.
  • the force acting upon f our guide rollers 20 during the rotation of the pan is composed of a first force necessary to support the weight of the'pan itself, a second force acting upon the lowerv surface of the pan to urge it upcoiler-gear mechanism is dividedinto two parts 3) and downwardly projecting inclined guide tube 3 which is sekcured to the lower surface o f the gear 2 to define said Y .passage B, a vertical arm or shaft 4, and pins 5 and 6 secured to the lower end of the shaft 4 which is integral with the gear 2.
  • the outer race of the bearing 10 issecured to a xed block 11 which in turn is rigid with a frame 12.
  • the'top part 30 is rotatably supported in correct, position by the ball bearing 10.
  • a helical pinion 14 fmeshingwith helical-gear .teeth 7 of the gear ⁇ 2 is mounted on a drive shaft 13, the pinion 14 and shaft 13 constituting a drive means coupled withthe upper coile'r member via' its gear 2.
  • the force ⁇ acting upon the top bearing 10 is composed kof a first force required to rotate the top part 30 while supportingiits weight, a second force necessary to 'maintain the top partin its correct ⁇ position against a force normally/'tending to bias it inga definite direction, andV a fr Vthird force caused by the unbalanced condition during rotation due to asymmetrical contiguration'of the lower portion.
  • the diameter' of the pan can be made smallenso that, even where the same gear mechanism is used, it is possible to make 1t have a smaller radius of gyration, thus increasingthe rate 'of acceleration or deceleration. Thisrneans that troubles occurring Vin the case of operating at even higher speed Vare greatly minmized, thereby providing a tube gear mechanism suitable for high speed operation.
  • Vthe bottom part 31 of the co'iler-gea'r mechanism comprises a shallow disc-shapedl pan 22 which is supported by four guide rollers 20, each having a ball bearing 21'Y (FIG. l) and receivedwithina ⁇ fitted in holes Zland 25, respectively, of the pan 22.V It
  • these pins and holes serve merely as a rotary motion transmitting device from the top part to the bottom part but do not restricttheir supported positions.
  • their relative axial positions are exible, i.e. there is freedomiof relative axial movement but'the rotation ofthe top, part is positively transmitted to the bottom part sothat they rotate in unison.
  • any forceacting upon the top'bearing 10 will not affect' the bottom bearings 21.
  • any force' acting upon the bottom bearings will not affect the top bearing.
  • the top and bottom bearings operate quite independently to supportthe coiler-'gear mechanism.
  • top bearing 10 would besubjected to forces of variousdi'rections so that Ait would not operate satisfactorily at high speed.
  • the top bearing were eliminated, and if Vtop and b ottom parts were constructed as a unitary structure,fthe coiler gear mechanisml would become unstable because itis. driven by bearing surfaces.
  • a Acoiler gear is divided into separate upper and bottom parts which are ⁇ respectively provided with'an anti-frictionbearing, ⁇ and ywherein a curved inclined tube 3 is substituted for the straight tubefo shownin FIGS; 1 and 3.
  • guide tube 3 provides moreeicient guiding action to the groove 23 (FIG. l)k on the outer periphery of the pan.
  • the pan is provided with holes 24 and 25 for receiving said pins orv dowels 5 and 6, respectively, and the discharge opening C near its periphery;
