Definitions

  • the invention relates to a spindle bearing for a double-twisting spindle according to the preamble of claim 1.
  • Conventional double-twisting spindles include a spindle bearing, a driven rotor element and a protective pot for receiving the spool.
  • Your spindle bearing has two storage areas. In a top storage area, the protective pot is rotatably mounted on the rotor element and relative thereto. In a sub-storage area, both the pressure forces of a tangential belt, which drives the rotor element by means of a whorl, and the axially acting forces are absorbed by the weight of the protective pot and the coil located therein.
  • the rolling bearings of the sub-storage area are designed for a typical service life of approx. 50,000 h.
  • the rolling bearings in the upper bearing area are designed so that they do not reach this life.
  • a spindle bearing for a double-twisting spindle is for example from the DE-A-195 02 135 known.
  • channels are introduced to Zusupplementarytician discharge of grease.
  • Each Rolling bearing is assigned a grease supply channel and a Fettab technicallykanal. Fettzu Beforekanal and Fettab technicallykanal are each connected to a Fettzu 800ö réelle or Fettabriosö réelle.
  • the grease supply opening or the grease discharge opening form on the outside of the bearing housing the conclusion of a horizontal channel.
  • the generic DE-A-102 50 423 describes a spindle bearing for a double-twisting spindle whose spindle rotor has a spindle shaft which is rotatably supported by means of an upper and a lower rolling bearing.
  • the bearing housing has a fat channel running transversely to the axis of rotation of the spindle rotor. Inside the bearing housing, the grease is distributed by means of a conical distributor ring and fed to the bearings. For the mounting of the distributor ring, a circumferential groove to be introduced into the spindle shaft is required.
  • Both the DE-A-195 02 135 as well as the DE-A-102 50 423 show spindle bearings, in which the accessibility of the grease channels is impaired by the position of the lubricant.
  • the possibilities of a compact design of the double-twisting spindle are limited by the position of the grease channels at half the height between the bearings of the lower storage.
  • a running from above through the Fadenleit analyses parallel to the axis of rotation of the spindle shaft and opening into the lower bearing means lubricant channel is easily accessible after removing the protective cup for the Befettungsvorgang.
  • the placement of a grease gun takes place in the vertical direction and is ergonomically favorable for the maintenance person.
  • the lubricant may enter the bearing area due to the vertical position of the spindle and the running vibrations of the bearing supported by gravity.
  • both the size of the passage for the lubricant and the holding action of the fastening screw are sufficient.
  • the lubricant passage passes through a ring which surrounds the spindle shaft and is firmly connected thereto.
  • a ring stabilizes the attachment and allows a secure engagement of the screw.
  • the rotating ring and the lower bearing device is surrounded by a stationary bearing housing and formed between the bearing housing and the ring a gap seal.
  • the gap seal prevents the lubricant introduced into the lower bearing device through the lubricant channel from rising upwards again. This is done in a simple manner by such a design of the ring that only a small distance between the ring and the bearing housing, whereby no additional sealing elements are needed here. Assembly costs associated with additional sealing elements are avoided.
  • the lower bearing means comprises two axially spaced rolling bearings, wherein above the upper roller bearing a lubricant reservoir is arranged, in which the lubricant channel opens.
  • a sufficient supply of lubricant can be introduced into the lower bearing device, which can be distributed during rotation of the rotor element under the influence of gravity so that both bearings are lubricated satisfactorily.
  • the spindle shaft is driven by means of a cup-shaped whorl, the whorl at least partially enclosing the bearing housing of the lower bearing device, a compact construction of the spindle bearing is possible.
  • Location and Training the whorl allow a largely uniform load on the bearings of the lower bearing device.
  • the spindle bearing according to the invention enables a compact, cost-effective design and an improvement in lubrication.
  • a spindle bearing 1 is shown with a protective pot 2.
  • the protective pot 2 is mounted on a spindle rotor.
  • the spindle rotor comprises the spindle shaft 3, the thread guide body 4, the ring 5 and the whorl 6.
  • the spindle shaft 3 is rotatably supported in the bearing housing 8 by means of the lower bearing device 7.
  • the axis of rotation 12 of the spindle shaft 3 is arranged vertically.
  • the bearing housing 8 is fixedly connected to a known for reasons of simplification, known per se spindle bank.
  • the lower bearing device 7 has two axially spaced rolling bearings 9, 10.
  • the whorl 6 is cup-shaped and on the in the representation of Fig. 1 lower end of the Spindle shaft 3 pressed on.
  • Fig. 1 shows from the screw connection only the fastening screw 13.
  • the screw connection by means of the fastening screws 13, 14, 15, as shown in the illustration of Fig. 3 is recognizable.
  • an upper bearing means 16 is arranged, on which the protective pot 2 is placed. As a result, the protective pot 2 is rotatable relative to the spindle shaft 3.
  • a coil can be plugged, from the in Fig. 1 only part of the sleeve 17 is shown.
  • the upper bearing means 16 comprises two vertically spaced rolling bearings 20, 21.
  • a Fadenleitkanal 22 as in Fig. 1 represented and for example from the DE-A-102 50 423 is known.
  • the fastening screws 13, 14, 15 are designed as hexagon socket screws.
  • Fig. 2 shows the fastening screw 13 in an enlarged view.
  • a lubricant channel 18 is introduced, which, starting from the hexagon socket in the screw head 19, the fastening screw 13 in the longitudinal direction as a bore.
  • the fastening screw 13 replaces a standard grease nipple.
  • the production of Fixing screw 13 is easy and inexpensive by drilling.
  • the bore forming the lubricant channel has, for example, a diameter of 1.2 mm.
  • the lubricant channel 18 opens into a cavity 23 above the rolling bearing 9 of the lower bearing means 7, wherein the cavity 23 serves as a lubricant reservoir.
  • the ring 5 is shaped such that it forms a gap seal 24 with the stationary bearing housing 8 surrounding it.
  • the protective cup 2 is detached from the spindle shaft 3.
  • the fastening screw 13 has become visible or exposed and created without additional effort a light, unobstructed access to the mounting screws 13, 14, 15.
  • the screw head 19 of the fastening screw 13 is marked in color and therefore recognizable without searching at first glance.
  • the color marking is in the detail X the Fig. 3 indicated by cross-hatching.
  • the introduction of the grease used as a lubricant is done with a grease gun.
  • the grease gun can, ergonomically favorable for the operator to be placed in a vertical position on the screw head 19 of the fastening screw 13.
  • the amount of grease required for the lower bearing device 7 is introduced through the lubricant channel 18 of the fastening screw 13 into the cavity 23.
  • the gap seal 24 prevents the grease from rising from the cavity 23 upwards and thus exits the lower bearing means 7.
  • the cavity 23 is dimensioned such that the amount of grease required for the adequate lubrication of the roller bearings 9, 10 does not completely fill the cavity 23.
  • the fat, respectively the oil in the grease can due to the vertical arrangement of the spindle shaft 3 and thus the vertical arrangement of the lower bearing means 7 and under the influence of gravity and the running vibrations, which is subjected to the lower bearing means 7, reach the rolling bearings 9, 10 and enter into this.
