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, the bearing being fastened to the housing, enclosed by it, and through the spindle shaft the bearing is held rotatably, and the lubricant moves in a closed circuit from the reservoir to the bearing which is arranged higher than the latter and back to the reservoir.
  • 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 the greatest load on the drive of the spindles, ie the highest number of revolutions thereof, 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 said to can be avoided according to the invention.
  • the reservoir rotates with the spindle shaft, that a fixed tube attached to the housing dips into the reservoir and forms the part of the circuit that leads from the latter to the bearing, that when the spindle begins to rotate, the lubricant in the reservoir before it reaches it maximum rotational speed flows against an opening at the immersed end of the tube, so that a back pressure forms at the opening, and that the position of the tube is selected in such a way that the opening when the maximum rotational speed of the lubricant is reached outside of the in the Reservoir located lubricant exposed to centrifugal force.
  • the invention also relates to a spinning or twisting spindle with a bearing lubricated according to the method, which rotatably holds the spindle shaft, which is characterized in that the spindle shaft and the reservoir are connected to one another and rotatable about a common axis, that the reservoir as one is formed upwardly open container, the side wall is provided with an upper edge which extends inwards to the housing immersed into the reservoir from above and forms a sealing gap with it, and that the part of the circuit leading from the reservoir to the bearing a tube leading from the reservoir to the bearing is formed, which has an opening located above the bearing.
  • the invention thus conveys the advantage in particular a lubrication method specially adapted to the spinning process: at the start of creating a winding, the oil rotating 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, in the reservoir 13 there is a liquid lubricant 28, e.g. Oil.
  • a housing 21 is e.g. attached to a spindle bench 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 rests on these bearings 23, 24 and is rotatably held 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 18 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. Such also prevents contamination of the lubricant 28 by fiber flying.
  • a lubrication process in which a strong supply of lubricant occurs automatically at startup, which is sufficient for the duration of the winding of a sleeve.
  • the supply of lubricant 28 is stopped when the normal operating state is reached, so that during normal operation for the circulation a lubricant is no longer used at all.
  • 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 piece 33 can be directed more or less precisely against the flow of the lubricant, i.e. 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 18 is kept at the value at which it just barely hits the opening 26 for a relatively long time.
  • semi-permeable sealing disks 33 can be located in the flow area the bearings 23, 24 are attached.
