Definitions

  • the present invention relates to a method for lubricating a bearing of a spinning or twisting spindle, which comprises a spindle shaft, a fixedly mounted housing and a reservoir containing a liquid lubricant and rotating with the spindle shaft, the bearing being fastened to, enclosed by the housing, and the spindle shaft is held rotatably by the bearing, and the lubricant moves in a closed circuit from the reservoir to the bearing, which is arranged higher than the latter, and back again to the rotating reservoir.
  • the lubricant is brought up from a reservoir and then passed over the parts to be lubricated when it flows down again for the purpose of lubrication.
  • Various working methods are known to bring the lubricant up:
  • German Patent No. 155 356 it rises up the spindle, exits at the end of a bearing attached at the top and comes back into a neck bearing housing.
  • British Patent Specification No. 698 141 oil is thrown against the inner wall of a cylinder by centrifugal forces. This is sprayed upwards and passes through an upper and a lower bearing.
  • German Patent No. 455 211 shows a device with an upwardly widening spindle shaft, the rotation of which causes the oil to move upwards along the shaft. The same is moved back along the inner wall of a hole.
  • German Patent Nos. 486 106, 538 624 and 654 948 relate to devices in which oil is conveyed upwards by means of a spiral groove or screw groove.
  • the known devices have the disadvantage that with the greatest load on the drive of the spindles, i. H. at the highest number of revolutions, or in other words, during the normal winding process of the spindle, the load on the spindle drive caused by the supply of the lubricant is also greatest.
  • the collapse of these maximum loads is disadvantageous for the drive, since it means an additional expenditure of energy.
  • this disadvantage is to be avoided and, in particular, the aim is to ensure that the bearing is only briefly lubricated during the acceleration phase and that the oil delivery and thus also the forced bearing lubrication are interrupted as soon as the spindle has reached a certain maximum rotational speed.
  • the invention is characterized in that a fixed tube attached to the housing dips into the reservoir and forms the part of the circuit leading from the latter to the bearing, that when the spindle begins to rotate, the lubricant in the reservoir before reaching its maximum rotational speed against one at the immersed end Existing opening of the pipe flows, so that a back pressure forms at the opening, and the position of the pipe is selected in such a way that the opening, when the maximum rotation speed of the lubricant is reached, is outside the lubricant located in the reservoir and subjected to centrifugal force located.
  • the invention also relates to a spinning or twisting spindle with a bearing lubricated according to the method, which rotatably holds the spindle shaft and with a reservoir connected to the spindle shaft and rotatable about a common axis, and is characterized in that the reservoir is open as an upward opening Container is formed, the side wall is provided with an upper edge which extends inwards to the housing immersed in the reservoir from above and forms a sealing gap with this, and that the part of the circuit leading from the reservoir to the bearing through a from the reservoir tube leading to the bearing is formed, which has an opening located above the bearing.
  • the invention thus conveys in particular the advantage of a lubrication method specially adapted to the spinning process: at the beginning of the creation of a winding, the oil which rotates with the reservoir is driven through the bearing. This gives the bearing vigorous lubrication. As the lubricant in the reservoir reaches full rotational speed, it is pressed against the side wall of the reservoir by centrifugal force. The tube is positioned in the reservoir at such intervals from its side wall and from its bottom that at this full rotational speed, ie during normal operation of the spindle, no more oil flows against the tube and thus against the opening at the end of the tube immersed in the reservoir.
  • FIG. 1 shows a hollow cylindrical spindle shaft 11 which can be rotated about an axis 12.
  • a reservoir 13 is firmly placed on the spindle shaft 11 and rotatable with it about the axis 12.
  • the reservoir 13 is provided with a vortex 14 provided for driving.
  • a clamping ring 15 is firmly placed on the shaft 11 and also rotatable therewith. Between the cylindrical portion of the clamping ring 15 seated on the spindle shaft 11 and a seal 16 carried by it, a sleeve 17, which is used, for example, to wind a thread, can be plugged on.
  • a spindle head which also serves to hold the attached sleeve 17.
  • the side wall of the reservoir 13 is provided with an upper edge 18 which extends inwards.
  • a liquid lubricant 28 e.g. B. Oil.
  • a housing 21 is, for. B. attached to a spindle bank 22 by means of screws. It is essentially of a hollow cylindrical shape and is arranged coaxially to the axis 12. A neck bearing 23 and a foot bearing 24 are fastened to the housing 21. The spindle shaft bears against these bearings 23, 24 and is held rotatably by these. The housing 21 encloses the bearings 23 and 24. In addition, it forms an enclosed space extending between the latter. A vertically arranged tube 25 is fixedly attached to the housing 21.
  • the tube 25 is provided with an opening 26, which is located on the front side of the tube 25 with respect to the direction of rotation of the reservoir 13.
  • the rim 18 prevents lubricant 28 from flowing out of the reservoir 13 at the top. This seal is further improved in that the edge 18 forms a sealing gap with the housing 21. This also prevents contamination of the lubricant 28 by fiber flying.
  • a lubrication process in which a strong supply of lubricant automatically occurs when starting up, which is sufficient for the duration of the winding of a sleeve.
  • the supply of lubricant 28 is terminated when the normal operating state is reached, so that no energy is used at all for the circulation of a lubricant during normal operation.
  • the pipe 25 comprises a pipe end piece 34 at its end located in the reservoir 13.
  • the lubricant which co-rotates with the reservoir 13 strikes the opening 26 essentially from the left-hand side in FIG. 2, generates a dynamic pressure thereon and is driven through this into the tube 25 and in this.
  • the pipe end piece 34 is thus bent in such a way that it extends away from the pipe 25 against the direction of rotation of the reservoir 13.
  • the amount of lubricant 28 flowing through the pipe 25 can be made variable and can thus be adapted to the given circumstances. This is achieved, for example, by making the flow cross section of the tube 25 changeable, for example by means of a valve or by squeezing the tube 25.
  • the pipe section 34 can be directed more or less precisely against the flow of the lubricant, i. H. position more or less precisely with respect to the rotation of the reservoir 13 in the tangential direction.
  • the amount of lubricant delivered can be varied by dimensioning the rotational speed of the incoming reservoir 13. This becomes large, for example, if the rotational speed of the lubricant 28 is kept at the value at which it just barely hits the opening 26 for a relatively long time.
  • semi-permeable sealing washers 33 can be attached in the flow area of the bearings 23, 24.
