Definitions

  • a godet for transporting and heating fibers comprises an outer and an inner cylindrical shell which define an annular space therebetween for the flow of a fluid heating medium, an end wall secured to the outer shell, and a bearing shaft attached to the end wall via radial and axial fitting surfaces.
  • a continuous layer of heat-insulating material is provided for the radial and axial fitting surfaces.
  • a godet construction having means to collect and return leakage oil from the outside of a bearing housing to the inside of the housing is disclosed.
  • This invention relates to a godet used in drawing apparatus and drum dryers preferably used for yarns, threads, webs and the like made of synthetic fibers and in particular to a godet having a double cylindrical shell defining a free annular space therebetween, guide means for directing the flow of a fluid heating medium required for heating the godet means, means for introducing the heating medium into the free annular space between the two cylindrical shells of the godet, a bearing shaft for the godet attached at the end wall via radial and axial fitting surfaces and supported in a bearing housing associated therewith so that the shaft is rotatable.
  • a godet of this type which has radial and axial fitting surfaces that-are partially covered with a heatinsulating material is disclosed in German Patent Application P 20 693.8 and the above-mentioned US. application.
  • the godet according to the parent application is constructed in such a manner that, when the fluid heating medium is introduced into the double shell of the godet, as little heat as possible is transferred to the bearing shaft. These heat losses from the heating medium cannot be entirely avoided, but are to be kept as low as possible. This is necessary in order to lessen the energy used for heating the godet shell to the required temperature and also for maintaining the bearing shaft at a low temperature to prevent an undesirably high. heating of the bearings of the bearing shaft in the bearing housing. Due to the contact points between the godet and the bearing shaft, the shaft is the cause for constant heat losses and constitutes an impediment to heating the godet shell to a maximally high temperature.
  • the godet has a heat-insulating layer that extends continuously as a ring over the radial fitting surfaces and as a sleeve over the axial fitting surfaces between the bearing shaft and the end wall of the godet.
  • this invention furthermore provides an arrangement such that in the hollow bearing shaft not only one pipe, but two pipes are provided, one surrounding the other with a space therebetween.
  • the external pipe of the two pipes should likewise be spaced from the inner wall of the bearing shaft.
  • the heating medium is introduced into the godet through the cross-sectional space of the inner pipe, and again returned through the open annular space between the inner wall of the outer pipe and the external wall of the inner pipe, but now a direct contact between the wall touching the heating medium and the bearing shaft is prevented. in this manner, the transfer of heat to the bearing shaft and thus to the bearings of the bearing shaft can be still further reduced.
  • a lubricant reflux or backflow bore in the housing wall underneath the shaft or the like and underneath the optionally provided bearing, for example, a lubricated ball bearing.
  • the bore is inclined at a certain angle obliquely downwardly from the outside toward the inside, since in this manner the oil can flow back into the interior of the bearing housing solely under the effect of gravity.
  • the oil flows to the outside not only at the lowest point of the bearing.
  • the oil must be conducted to the reflux bore, for which purpose all types of guide means are possible.
  • the-bore is to be provided advantageously at that point where the bearing hub, visible outside of the housing, is surrounded by a wound guard ring.
  • the bore then extends transversely through, the wound guard ring as well as through the wall of the housing; namely, suitably at the lower apex of the wound guard ring.
  • the leakage oil can be collected in this wound guard ring over the entire circumference thereof, when the inner side of the ring has an annular groove wherein the oil can accumulate and from where the reflux bore extends into the interior of the housing.
  • FIG. 1 shows a longitudinal section through a godet and the wall of the housing of its associated bearing shaft
  • FIG. 2 shows a section similar to that of FIG. 1 through another embodiment of the bearing shaft for the godet.
  • FIG. 1 that portion of godet 2 which is connected to a hollow bearing shaft 1 is illustrated.
  • the godet has an outer cylindrical shell or jacket 3 and an end wall 4 attached to the outer shell 3.
  • An inner cyoindrical shell or jacket 5 is also attached on the end wall 4 and is spaced a small distance from shell 3.
  • annular space 6 Between the outer and inner shells is an annular space 6, which is subdivided into several chambers.
  • a fluid heating medium, e. g., steam, water, etc. flowing through space 6 is supplied through the eentral pipe 7 in the hollow bearing shaft 1.
  • the bearing shaft 1, illustrated with bearings 9 and 10 shrink-fitted thereto, has a mounting flange 11 on i the end face which faces the godet 2.
  • This flange is attached to the godet 2 from the end wall 4 of the godet by means of screws 12.
  • the mounting flange In the axial and radial directions, the mounting flange has fitting surfaces which mate with corresponding fitting surfaces provided by end wall 4. The spaces between the fitting surfaces are provided with continuous heat-insulating material 19,
  • ring 19 and sleeve 20 may be integral or formed separately.
  • a heat loss to the bearings can be prevented by a special arrangement provided within the hollow bearing shaft through which the heating medium is fed and discharged.
  • the external pipe 21 encompasses the internal pipe 7 and is spaced therefrom.
  • an interspace 31 is also left free between the external pipe 21 and the inner wall surface of the bearing shaft 1, so that here, too, a metallic contact with the bearing shaft 1 is avoided.
  • the space between the outer wall surface of the external pipe 21 and the inner wall surface of the bearing shaft 1 can be achieved solely by the exact supporting of the pipes 7, 21 at the front and rear ends of the bearing shaft 1.
  • a ring spacer 22 for this purpose which is also manufactured of a heat-insulating material, e.g., a ceramic.
  • FIG. 2 the internal structure of a wall of a bearing housing for a drawing plant is additionally illustrated.
  • the bearing shaft 1 in this embodiment is supported in a wall of a bearing housing via a ball bearing 9.
  • This ball bearing is lubricated with oil fed through a bore 23.
  • the oil which penetrates toward the outside through the ball bearing 9, is returned into the interior of the bearing housing through a bore 24 provided below the ball bearing 9 in the wall 4 of the housing.
  • the housing is sealed off toward the outside by a labyrinth seal 26 formed with a wound guard ring 25; this sea] essentially prevents the flowing of leakage oil through the gap between the mounting flange ll and the ring 25.
  • leakage oil should flow through the seal 26, after all, it will collect in the annular groove 28 on the inside of the wound guard ring 25 and will flow back into the housing from the groove through a lubricant reflux bore 27.
  • the bore 27 extends from the outside obliquely in the downward direction into the bearing housing. This bore ensures with certainty that each drop of leakage oil is returned into the bearing-housing.
  • a heated godet for use with drawing apparatus and drum dryers that transport synthetic fibers which comprises a cylindrical outer shell for contacting said fibers; an inner cylindrical shell, said shells being spaced from each other to define an annular space therebetween; means for feeding a fluid heating medium into and for discharging the heating medium from the annular space between the two cylindrical shells; an end wall secured to said outer cylindrical wall; a bearing shaft attached to the end wall of the godet via radial and axial fitting surfaces provided by a mounting flange secured to said bearing shaft, said flange being secured to said axial and radial surfaces that mate with corresponding fitting surfaces provided by said end wall, a layer of heat-insulating material extending continuously over the radial and axial fitting surfaces; at least one bearing fitted to an outer surface of said bearing shaft, said means for feeding and discharging the fluid heating medium being centrally located in said bearing shaft and including two pipes; one encompassing the other and spaced therefrom within the bearing shaft; and means for spacing the one pipe encompassing the other away from
  • the spacing means comprises a ceramic sleeve positioned between said one pipe and the inner surface of the bearing shaft.
