Definitions

  • the invention relates to an opening roller unit for open-end spinning machines, with a shaft rotatably mounted in a bearing housing, on the free end protruding from the bearing housing, an opening roller is rotatably attached, which preferably has a removable, axially attached cover on its end facing away from the bearing housing is covered, and which engages behind the bearing housing to form a cavity which is sealed to the bearing housing by an annular sealing gap.
  • Such an opening roller unit is described in DE-OS 27 52 591.
  • dirt such as micro dust
  • a sealing gap between the bearing housing and the opening roller.
  • the opening roller In the known opening roller unit, the opening roller must be removed from the shaft for this, which is relatively cumbersome.
  • a opening roller unit is known from DE-PS 31 23 480, in which the The opening roller unit essentially consists of a base body and an opening roller ring fitted with a fitting thereon.
  • the cavity is covered by the opening roller ring. If you want to clean the cavity, it is still necessary here that at least the opening roller ring is removed. Since the opening roller ring is pressed onto the base body by means of a tensioning element, exposing the cavity for cleaning purposes is also relatively complex there.
  • the object of the present invention is therefore to improve an opening roller unit of the type mentioned at the outset in such a way that the cavity can be freed from the micro-dust which has penetrated through the sealing gap in a simple manner.
  • At least two cleaning channels are formed in the opening roller which are arranged essentially parallel to the opening roller axis and which extend from the cavity to at least one end face of the opening roller.
  • the easily removable cover needs to be removed, so that compressed air can be fed into one of the two cleaning channels with a compressed air nozzle.
  • the dust located in the cavity is then blown out of the other cleaning channel.
  • This cleaning can be carried out easily, since neither a removal of the opening roller ring nor a dismantling of the opening roller unit is necessary, so that the service life of the opening roller unit can be easily extended.
  • a cleaning of the cavity is usually only then if it is easy to do, as here.
  • the cleaning of the cavity can be accomplished particularly easily if the cleaning channels extend through the cover. Then it is not even necessary to remove the cover.
  • the opening roller consists of a base body and an opening roller ring equipped with replaceable fittings, and if the cleaning channels are formed from the base body. Then the cleaning of the cavity can take place regardless of the type of the opening roller ring applied.
  • the opening roller consists of a base body and a fitting-equipped opening roller ring fitted thereon, and if the cleaning channels are formed on the inner top side of the opening roller ring facing the base body.
  • the advantage here is in particular that opening roller units which are already in operation and which do not yet have any cleaning channels can be easily retrofitted as soon as the opening roller rings have to be replaced anyway due to wear. Once such an opening roller ring is attached, the cleaning of the cavity is considerably simplified.
  • the cavity is formed in the base body and if essentially radial connecting channels are formed in the base body, which from the outer upper side of the opening roller facing the opening roller ring Lead the main body to the cavity. So there is a direct connection between the Connecting channels and the cleaning channels, without the mechanical strength of the base body would suffer.
  • the cleaning channels are arranged diametrically opposite one another. As a result, particularly rapid cleaning of the cavity is achieved when a cleaning duct is pressurized with compressed air.
  • an opening roller unit for open-end spinning machines is shown.
  • the opening roller unit comprises a bearing housing 1 in which a shaft 2 is rotatably mounted. At its free end protruding from the bearing housing 1, an opening roller 3 is pressed onto the shaft 2 in a rotationally fixed manner.
  • the opening roller 3 consists of a base body 4 pressed onto the shaft 2 and a opening roller ring 5 pushed onto the outer upper side of the base body 4. On the end facing away from the bearing housing 1, the opening roller 3 is covered by a cover 7.
  • the cover 7 can be screwed to the base body 4 by means of three screws 8 distributed over the circumference, of which only the center lines are indicated; however, it is also possible for the cover 7 to be screwed onto the shaft 2 via a central screw.
  • the cover 7 also has a collar 9, with which it braces the opening roller ring 5 against the collar 6 of the base body 4.
  • the base body 4 mounted on the shaft 2 in a rotationally fixed manner engages over the bearing housing 1 and forms a cavity 10. This cavity is sealed off from the bearing housing 1 by a sealing gap 11 formed between the bearing housing 1 and the base body 4.
  • the cavity 10 is open to the outer upper side of the base body 4 through two diametrically opposite radial connecting channels 12.
  • the opening roller ring 5 has on its radial upper side facing the base body 4 a circumferential recess 13 into which the connecting channels 12 open.
  • a centering shoulder 14 is provided on the base body 4, which has an outer diameter which corresponds to the inner diameter of the recess 13.
  • the recess 13 is open axially towards the end of the opening roller ring 5.
  • Two cleaning channels 15 extend diametrically opposite one another from the recess 13 parallel to the axis of the opening roller 3 to the cover 7.
  • the cover 7 is penetrated by openings 16 congruent with the cleaning channels 15, so that the cleaning channels 15 open into the open.
  • FIG. 4 The exemplary embodiment according to FIG. 4 is described below.
  • the same reference numerals are used for identical and similar components. Only the differences from the exemplary embodiment described in FIGS. 1 to 3 will be discussed.
  • two axial cleaning channels 15 are provided in the base body 4, which open directly into the cavity 10 and extend to the cover 7. No openings are provided in the cover 7, and there are no grooves and recesses on the inside of the opening roller ring 5 because they are not necessary.
  • a certain amount of micro dust gets into the cavity 10 through the sealing gap 11, which can never be completely sealed.
  • the cavity 10 is able to receive a certain amount of micro dust without this not being shown Bearing between the bearing housing 1 and the shaft 2 would be affected. If the predetermined amount of micro dust is exceeded, it can happen that the micro dust gets from the cavity between the bearing housing 1 and the shaft 2 and from there into the shaft bearing, which leads to an impairment of the shaft bearing. It is therefore desirable to clean the cavity 10 from time to time.
  • only a pneumatic tool e.g. B. the existing in each textile compressed air gun to be attached to one of the two openings 16 in the lid 7, after which compressed air is then applied.
  • the cavity 10 can be cleaned in a similar manner.
  • the cover 7 has to be removed, so that one can get directly to one of the cleaning channels 15 with the compressed air tool.
  • the compressed air fed in there arrives directly into the cavity 10 and from there back into the cleaning channel opposite Free. Then the cover 7 is reassembled using the screws 8.
  • a cleaning channel is formed on the inside of the opening roller ring, while the other cleaning channel is formed in the base body.
