Definitions

  • the invention relates to a twisting head rotor for a cabling machine according to the preamble of claim 1.
  • a first thread is withdrawn from a first stationary feed bobbin arranged above a hollow spindle, while a second thread withdrawn from a second feed bobbin is introduced centrally from below into the hollow spindle.
  • the second thread exits laterally from the hollow spindle and rotates in a thread balloon around the first feed bobbin before it is brought together by a above the hollow spindle freely rotatably mounted Zwirnkopfrotor with the first thread.
  • the Zwirnkopfrotor has two pairs of balancing rollers, which are each arranged on a common axis of rotation. The two axes of rotation are arranged in mutually parallel bearing bores which extend transversely to the longitudinal axis of the Zwirnkopfrotors.
  • the bearing of the two axes of rotation takes place in two juxtaposed arranged in the bearing bores bearings.
  • the rolling bearing pairs are mutually spaced by a arranged in a circumferential groove in the interior of the bearing bores spacer.
  • relubricated or life-lubricated bearings are used for the bearings of the axes of rotation .
  • the service life of the roller bearings of the twisting head rotor depends largely on their lubrication condition. Due to the centrifugal forces acting on the rolling bearings due to the rotation of the twisting head rotor, the grease used as the lubricant is pressed outwards, resulting in deficient lubrication due to the oil separation from the bearing Adjusting lubricant. This requires replacement of rolling bearings or regular relubrication.
  • the use of lifetime-lubricated bearings also eliminates due to the incoming deficient lubrication, caused by the centrifugal force, from. Again, the centrifugal force leads to a separation of the oil contained in the lubricant, which then emerges from the rolling bearings. The part of the lubricant remaining in the rolling bearings is not suitable for ensuring adequate lubrication during operation of the twisting head rotor. In addition, these bearings are no longer relubricated due to the design.
  • the DE 202 09 091 U1 describes a Zwirnkopfrotor of the aforementioned type, which is designed to simplify the relubrication of the rolling bearings such that in each case a compensating roller pair is mounted together with the rolling bearings and the axis of rotation in a roller cartridge.
  • the roller cartridge can be removed from the bearing bore of the twisting head rotor in order to relubricate the rolling bearings by means of a specially developed lubricating device.
  • the respectively disassembled roller cartridge is inserted into the lubricating device, to which a lubricant press is connected.
  • this solution has proved to be less practicable, since the cost of removing and installing the roller cartridge has only slightly reduced compared to the complete replacement of the bearings when they need to be replaced due to the lack of lubrication.
  • the invention is based on the object to provide a Zwirnkopfrotor that allows easy re-lubrication of rolling bearings without additional installation work.
  • one of the two bearing bores is connected to a connection device for supplying a lubricant and the two bearing bores are connected to each other by a through hole.
  • connection device can be connected via a connecting bore with one of the bearing bores.
  • the through-hole and the connecting bore may be substantially coaxial with the axis of rotation, which may be manufacturing aspects of the Zwirnkopfrotors is advantageous.
  • connection device can be arranged in the region of the axis of rotation of the twisting head rotor. This allows the connection of a Schmierstoffzu GmbHvortechnisch such as a lubricant press above one of the two bearing bores.
  • connection device can be arranged coaxially to one of the axes of rotation.
  • the supply of lubricant through the axis of rotation of one of the bearing bores is perpendicular to the axis of rotation of the Zwirnkopfrotors, which may be characterized by a better accessibility of the connection device.
  • the spacer means may be formed as spacers, which are each arranged in a radially circumferential groove of the bearing bores.
  • a circumferential channel-shaped recess may be introduced, which has a smaller cross section than the groove, which prevents the touching of the bottom of the recess by the respective spacer ring.
  • the present invention carried out Zwirnkopfrotor allows the almost simultaneous supply of a lubricant to both pairs of bearings by the introduced by a connection device in a bearing bore lubricant spreads through the channel-like recess behind the spacer ring through the through hole in the other bearing bore.
  • a homogenization of the lubricant supply is achieved by the spacer rings.
  • the spacer ring can be interrupted in the circumferential direction by a ring segment in order to release the through-hole at least in sections for supplying the lubricant to the roller bearings.
  • the flow of lubricant is improved by the one bearing bore in the direction of the other bearing bore.
  • the mobility of the spacer ring may be limited by an elevation disposed adjacent the through-hole and disposed in the groove.
  • the sectionally extending in the circumferential direction of the groove survey interrupts the recess in the groove partially, whereby it is achieved that the spacer rests on its positioning with one of its ends on the survey. If the through hole is covered by the one end of the spacer ring, the spacer ring can be returned due to the build-up lubricant pressure in the recess in its ideal position, whereby the through hole is released again.
  • FIG. 4 is an enlarged detail sectional view X of FIG .. 3
  • FIG. 1 shows a twisting head rotor 1 as shown in FIG DE 197 00 222 C1 is described, the disclosure of which is made the content of the present description.
  • the Zwirnkopfrotor 1 is provided with two superposed, perpendicular to the rotation axis 14 of the Zwirnkopfrotors 1 bearing bores 2a, 2b.
  • the bearing bores 2a, 2b are offset relative to the axis of rotation 14 of the twisting-end rotor 1 in each case offset to the rear, as shown in Fig. 1.
  • the bearing bores 2a, 2b serve to receive a respective rotation axis 3a, 3b, which are mounted in the respective bearing bores 2a, 2b by means of two roller bearings 4.
  • two balancing rollers 5 are arranged opposite one another at the end, which are spaced apart from each other by the twisting-head rotor 1.
  • the bearing bore 2a, 2b is divided by a coaxial with the longitudinal axis of the bearing bore 2a, 2b circumferential groove 6 in two sections, as shown in Fig. 2, which serve the arrangement of the two bearings 4 in the respective bearing bore 2a, 2b.
  • a spacer ring 7 is arranged, which mutually spaced the rolling bearing 4 and secures against axial displacement.
  • the groove 6 additionally has a radially encircling, preferably channel-shaped recess 8 at its bottom, which has a smaller cross-section than the groove 6.
  • the cross section of the recess 8 is chosen such that the touching of the bottom of the recess 8 is prevented by the located in the groove 6 spacer ring 7.
  • the bearing bores 2 a, 2 b are connected to one another by a through bore 9 extending coaxially to the axis of rotation 14 of the twisting-end rotor 1.
  • the upper bearing bore 2a in turn is connected via a connecting bore 10 with a connection device 11, such as a grease nipple, for supplying a lubricant.
  • the spacers 7 are designed as retaining rings, which are interrupted in the circumferential direction by an annular gap.
  • a survey 12 is provided, which extends in sections in the circumferential direction of the groove 6.
  • the spacer ring 7 rests with one of its two ends on the elevation 12, that is, the elevation 12 is located between the annular gap.
  • the spacer ring 7 is positioned relative to the through-hole 9 such that the opening of the through-hole 9 is generally largely exposed to ensure the passage of the lubricant.
  • the supply of the lubricant is preferably carried out by a connectable to the connection device 11 lubricant press.
  • the lubricant passes through the connecting hole 10 in the recess 8 behind the spacer ring 7 of the upper bearing bore 2a.
  • the recess 8 channels the lubricant From there, the lubricant between the interruption of the spacer ring 7 pushes outwardly towards the two rolling bearings 4.
  • the lubricant is pressed through the through hole 9 between the bearing holes 2a, 2b in the lower bearing bore 2b and occurs There to also extend in the direction of the bearings 4 of the lower bearing bore 2b.
  • the further distribution of the lubricant is effected by the centrifugal force acting during operation, whereby the relubrication only from the interior of the twisting head rotor 1 makes sense.
  • the rolling bearings 4 are sealed on one side on their compensation rollers 5 side facing.
  • one of the two axes of rotation 3 a, 3 b is connected to a connection device 11.
  • a lubricant guide channel 15 extends coaxially to the longitudinal axis of the rotation axis 3a, starting from the connection device 11 into the region of the through-bore 9 between the bearing bores 2a, 2b, as shown in FIG.
  • the relubrication of the rolling bearing 4 can be carried out from the side of the Zwirnkopfrotors 1 ago.
  • the lubricant exits radially from the Schmierstoffleitichkanal 15, and is arranged on a arranged between the bearings 4 disc 13 of the Through hole 9 and the annular gap of the spacer ring 7 of the bearing bore 2a supplied.
  • the lubricant enters via the through hole 9 in the annular gap of the spacer ring 7 of the bearing bore 2b.
  • the lubricant emerging from the annular gaps of the spacer rings 7 is further distributed in the bearing bores 3 a, 3 b towards the roller bearings 4.
  • the disk 13 is equipped with appropriately designed lubricant grooves, which promote the distribution of the lubricant.
