Definitions

  • the invention relates to a yarn winding device, in particular in ring spinning machines with a cylindrical spindle bearing housing according to the preamble of patent claim 1.
  • spindle bearing housings It is common practice to clamp such spindle bearing housings to the spindle bench by applying an external thread to the spindle bearing housing in the area of the spindle bench and below, onto which, after inserting the spindle bearing housing, a nut is screwed from above into the bore of the spindle bench, with the interposition of a washer is, which presses the flat ring flange located above the bore against the spindle bench, whereby the spindle bearing housing is fixed to the spindle bench in a desired position.
  • the spindle shaft can either be arranged beforehand in the spindle bearing housing. or subsequently introduced into it.
  • the aim of the present invention is to provide a yarn winding device of the type mentioned at the outset, with which the fastening of the spindle bearing housing to the spindle bench is possible with little production and assembly expenditure, without the reliability of the fastening being impaired.
  • the invention provides that as a fastening means below the bore axially displaceable with the outer area at the top on the underside of the spindle bench, flattened plate spring arrangement and underneath a snap or retaining ring provided in an annular groove of the spindle bearing housing are provided, the from below on the inside of the disc spring and presses it against the spindle bench.
  • the idea of the invention is thus to be seen in the fact that one does not fasten special bolts as in DE-OS 35 43 197, but rather the circular cylindrical spindle bearing housing itself by means of a plate spring and a retaining ring on the spindle bench.
  • the invention is based on the consideration that, with suitable mounting with such plate springs, the axial clamping forces required for a perfect fastening of the spindle bearing housing can be applied.
  • the axial contact forces should be 2000 to 4000 N and preferably 3000 to 3500 N.
  • a particularly preferred method for fastening a spindle bearing housing of a yarn winding device provides that a tool simultaneously the disc spring located on the spindle bearing housing and lying against the spindle bench from below, close to the inner region and grips the retaining ring, which is axially distant from it as far as possible, from below and, independently of one another, axially displaces it in the direction of the spindle bench until the retaining ring snaps into the associated annular groove without contact with the disc spring or at least without substantial axial force transmission from the retaining ring to the disc spring , whereupon the inner area of the plate spring comes to rest against the snap-in retaining ring by axially pulling off the tool.
  • annular tool is used, the inner diameter of which is only slightly larger than the outer diameter of the spindle bearing housing in the region of the annular groove and which has an inner step-shaped and preferably flat bearing surface for the retaining ring, to which radially outside a direction connects the plate spring extending ring projection, the axial extent of which is somewhat larger than the thickness of the retaining ring.
  • the plate spring is not largely flattened over the retaining ring, but rather independently of it by a suitable tool, whereupon - preferably with a different part of the same tool, the retaining ring independently of the plate spring into the assigned ring groove is snapped.
  • the axial displacement the inner area of the plate spring and the retaining ring are therefore carried out by the same tool, but independently of one another.
  • the retaining ring can expand or contract radially unhindered by the considerable axial forces of the plate spring, so that a radial snapping in alignment with the annular groove is easily possible.
  • the axial contact pressure exerted by the plate spring on the holding ring in the assembled state is so great that, taking into account the coefficient of friction between the plate spring and the holding ring and the contact angle of the contact surfaces, radial expansion of the holding ring is not possible, so that this is not only due to its inherent nature Clamping force, but also due to the high frictional contact between it and the plate spring is prevented from radial expansion and thus there is no risk in rough operation that, for example, even if the spindle is unbalanced, the retaining ring snaps out of its own ring groove.
  • Another object of the invention is to simplify the manufacturing and assembly work even further by using only a single fastening means.
  • a second solution according to the invention is to achieve the aforementioned improvement in that a clamping ring is provided as a fastening means below the bore with the outer area at the top on the underside of the spindle bank, slightly conically recessed away from the spindle bank, the inner edge of which engages in a self-locking clamping engagement is brought with the outer periphery of the spindle bearing housing at the height of the clamping ring, such that when exercised an axial force on the spindle bearing housing upwards, the clamping engagement between the outer circumference and the clamping ring is strengthened and the spindle bearing housing is thus held securely on the spindle bank.
  • the clamping ring can apply the necessary return spring forces, it is provided according to a preferred embodiment that the clamping ring consists of spring steel. Accordingly, the plate spring mentioned above should also consist of spring steel.
  • a particularly preferred embodiment provides that the spring ring is provided with slots distributed over its circumference, starting from the inner edge and extending in particular radially. In this way, numerous radial spring tongues are formed on the inner circumference of the clamping ring, which can engage particularly firmly and independently of one another in the outer circumference of the spindle bearing housing.
  • a particularly good contact of the clamping ring on the spindle bench is achieved if the clamping ring has a flat ring region radially outward following the conical part, which lies flat against the flat lower surface of the spindle bench.
  • a circular cylindrical stabilizing area is provided radially on the outside of the clamping ring.
  • the clamping ring can be applied without excessive friction to the spindle bearing housing arranged on the spindle bench until the clamping ring rests on the underside of the spindle bench, and only by exerting an axial force which elastically deforms the clamping ring on the clamping ring in the direction of the spindle bench on a radius between the Outside area and the inner edge of the final clamping engagement between the spindle bearing housing and the clamping ring can be produced.
  • the deformation clawing the clamping ring on the spindle bearing housing is therefore expediently only produced when the clamping ring has been brought relatively easily to the fastening point on the spindle bench or the spindle bearing housing inserted therein.
  • a preferred method for attaching the clamping ring of the above-described solution according to the invention is that the clamping ring is brought onto the spindle bearing housing mounted on the spindle bench from below to rest on the spindle bench and then by means of a hollow cylindrical tool pushed onto the spindle bearing housing from below Part of the clamping ring from an annular end edge of the tool is acted upon axially in the direction of the spindle bench with a force K such that the conical part is elastically deformed on the outer circumference of the spindle bearing housing while slightly grinding up the inner edge, and that the tool is then pulled off axially, the Tapered part relaxed again and thus the inner edge engages like a claw in the outer circumference of the spindle bearing housing.
  • the clamping forces for the arrangement of the plate spring or the clamping ring are preferably applied by a special lever clamping device.
  • a circular cylindrical and fixed spindle bearing housing 11 extends axially from top to bottom through a slightly larger bore 12 in a horizontally running spindle bank 13. Above the bore 12, the spindle bearing housing 11 has a flat and flat annular flange 14, which is from above rests on the flat surface of the ring bank 13.
  • a spindle shaft 27 Arranged in the spindle bearing housing 11 from above is a spindle shaft 27, which is only indicated in FIG. 1 and rotates at high speed, to which a drive whorl and a winding tube are concentrically attached in a manner not shown.
  • annular groove 21 is provided in the periphery of the spindle bearing housing 11, into which a retaining ring or snap ring 18 is snapped, on which the inner region 17 of a disc spring 15 arranged above it is supported, the outer region 16 of which is from below to the lower surface of the spindle bank 13 is pressed.
  • the contact pressure is between 3000 and 4000 N.
  • Fig. 3 it is illustrated how by means of an annular tool 19, the retaining ring 18 can be moved axially from below over the bearing housing until it snaps into the annular groove 21 without the forces for the flat printing of the plate spring 15 being simultaneously applied via the retaining ring 18 have to.
  • the ring-shaped tool 19 has a bore 28 on the inside, the diameter of which is slightly larger than the outside diameter of the spindle bearing housing 11 in the region of the ring groove 21. Below the annular groove 21, the outer diameter of the spindle bearing housing 11 can decrease - as shown in FIG. 1 -, but must not widen, since otherwise the retaining ring 18 could not be pushed on from below.
  • the tool 19 has a flat ring step 22, on which the retaining ring 18 rests in the not yet assembled state.
  • a ring projection 23 follows in the direction of the plate spring 15, the axial extent 24 of the ring step 22 of which is somewhat larger than the thickness 25 of the retaining ring 18.
  • the lower side of the plate spring lies on the end face of the axial ring projection 23 15 near the interior 17.
  • the annular step 22 moves the retaining ring 18 on the spindle bearing housing 11 without contact or force transmission from the retaining ring 18 to the plate spring 15.
  • the retaining ring 18 can thus expand freely when pushed on according to the outer circumference of the spindle bearing housing 11 and snap into the annular groove 21 after reaching the annular groove 21. Only when this has been done is the tool 19 axially withdrawn, the inner region 17 of the plate spring 15 resting on the retaining ring 18 from above and the spring forces now being transmitted from the retaining ring 18 to the spindle bearing housing 11.
  • the attachment is not only safe and reliable, but also extremely easy to manufacture, which is preferably done by the assembly tool 26 shown in FIG. 2.
  • the assembly tool 26 has a bracket 29 which extends from above over the upper opening of the spindle bearing housing 11 and which engages by means of a centering projection 30 in the shaft bore of the spindle bearing housing 11 from above.
  • an arm 29 'of the bracket extends laterally past the spindle bank 13 downwards, where an actuating lever 32 is fastened by means of a pin 31, which at its end extending to the spindle bearing housing 11 shows the end shown in FIG. 3 in detail
  • Lifting tool 19 carries, which is suitably pivotally mounted on the lever 32 about an axis 33 perpendicular to the plane of the drawing. On the side facing away from the tool 19, the lever 32 is made very long.
  • the ratio of the lever arms F1 and F2 is about 1:20, so that when the lever is depressed in the direction of the arrow in FIG. 2, a 20-fold increase in force is achieved.
  • the bracket 29 is supported at the top with the centering projection 30 and the adjacent areas on the upper end face of the spindle bearing housing 11.
  • the spindle bearing housing 11 can be fastened to the spindle bench 13 quickly and securely by means of the retaining ring 18 and the plate spring 15. After assembly, the pin 31 is pulled out, and the bracket can be removed men and used to assemble the next spindle bearing housing 11.
  • the bracket 29 is pivotally attached via a swivel joint 34 to a holder 35 which has a central bore 36 which can be placed from above onto the spindle bearing housing 11 and the ring flange 14, so that a perfect hold is ensured during the assembly process.
  • the bracket 29, 29 ' can be pivoted up into the position indicated by dashed lines in Fig. 2, so that an easy attachment and removal of the assembly tool 26 is ensured.
  • a plate spring 15 with a maximum spring travel of 1.3 mm is preferably selected, the spring force increasing within a spring travel of 0.5 to 1.0 mm from approximately 1800 N to 3700.
  • FIG. 6 an existing spring steel clamping ring 15 'is shown, which from a central opening 38 surrounding inner conical part 15'a, a radially outward adjoining perpendicular to the ring axis extending flat ring part 15'b and a radially outer adjoining circular cylindrical Part 15'c, which extends from the flat part 15'b in the same direction as the conical part 15'a.
  • the conical part 15'a is provided with evenly distributed over the circumference, starting from the inner edge 17 'radially extending slots 37, between which spring tongues 37' are thus formed.
  • the diameter in the central opening 38 corresponds essentially to the diameter of the outer circumference 18 '(Fig. 4) of the spindle bearing housing 11 at the height of the attachment point of the Clamping ring 15 'on the spindle bearing housing 11.
  • the clamping ring 15' according to FIG. 6 can be pushed onto the spindle bearing housing 11 according to FIG. 4 from below with the flat ring surface 15'b upwards until the flat surface 15'b is the lower one Surface of the spindle bank 13 touches.
  • a hollow cylindrical tool 19 ' is pushed onto the spindle bearing housing 11 from below, the inside diameter of which corresponds essentially to the outside diameter of the spindle bearing housing 11, so that the tool 19' can be pushed onto the spindle bearing housing 11 from below .
  • the tool 19 ' On the side facing the spindle bank 13, the tool 19 'has an end region 40 with a significantly enlarged inner diameter, so that an inner ring edge 39 is formed on the end face, which comes into engagement with the conical part 15'a when the tool 19' in the direction of Arrow in Fig. 5 is pushed onto the spindle bearing housing 11.
  • the point where the annular force acts on the clamping ring 15 is indicated in FIG. 4 by two arrows pointing upwards.
