Definitions
- the invention relates to a winding spindle for winding threads into a plurality of bobbins according to the preamble of claim 1.
- a generic winding spindle is known from DE 2 261 709 AI.
- the known winding spindle is used in a winding machine for parallel winding several threads into coils.
- the winding spindle is arranged cantilevered on a spindle carrier, wherein the projecting part of the winding spindle is designed as a chuck for receiving and fixing of winding tubes.
- the chuck is hollow cylindrical and connected via a hub with a arranged inside the winding spindle drive shaft.
- the drive shaft is rotatably mounted in a hollow cylindrical hollow carrier, wherein the hollow carrier projects into the interior of the chuck.
- the drive shaft for connecting a drive arranged on the spindle carrier must have a relatively large length.
- the chuck lowers with increasing coil weight and thus leads to a bending load of the drive shaft.
- the drive shaft is designed in several parts, wherein a front bearing shaft with the chuck and a rear bearing shaft are connected to the drive. Between the rear Bearing shaft and the front bearing shaft is provided an intermediate shaft, which is connected via flexible couplings with the bearing shafts. Such couplings are directly connected by a press connection with the shaft ends.
- shrink press joints affect depending on the joint diameter, the strength of the drive shaft.
- a lowering of the chuck is possible at full coil load without a forced deformation in the drive shaft.
- the reduction can be advantageously absorbed by an angular deformation in the couplings, the clamping allow the shaft ends of the bearing shafts and the intermediate shaft, a thickening of the waves.
- the drive shaft can be made substantially thicker and the high Umlaufbiegemomente and the resulting reactive loads for the bearings are avoided.
- the development of the invention is preferably carried out, in which the clamping elements are each formed of two half-shell-shaped clamping parts, which include a fitting bore between them and are screwed together.
- the diameter of the shaft ends and the fitting bore of the clamping parts can be matched to one another in such a way that, as it were, a screwable press fit is created.
- Such a split clamp connection between the coupling and the shaft ends has therefore proven particularly useful.
- the clamping elements of one of the couplings associated with the shaft ends are connected to one another at least by an axial and transverse elastic coupling means.
- a flexurally elastic coupling means for example, corrugated pipe elements or claw elements could be used.
- the intermediate shaft is resiliently supported by a plurality of damping bearing against the hollow support. This can be avoided in particular the vibration transmission via the couplings. Since the intermediate shaft is kept essentially free of transverse force and bending moment, the damping bearings essentially act only on resonances. In addition, a very stable guidance of the intermediate shaft is achieved within the hollow carrier.

This is in particular a tilting of the bearings avoided.
- the bearing is supported elastically with respect to the hollow support via the sleeve damping rings, so that the bearing shaft relative to the hollow support can perform relative movements for the purpose of damping.
- it is provided to form a bearing of the rear bearing shaft within a bearing bush, wherein the bearing bush is elastically supported by means of a plurality of sleeve damping rings relative to the hollow support. This can be attenuated both from the drive side and from an output side advantageously occurring vibration loads.
- the sleeve damping rings are preferably formed by an inner sleeve and an outer sleeve enclosing the inner sleeve. Whereby a rubber element is enclosed between the inner sleeve and the outer sleeve.
- the spring characteristic of the rubber element between the inner sleeve and the outer sleeve can be formed prior to installation with predetermined damping characteristics and adapted to the installation location and the installation situation.
- the winding machine according to the invention is characterized in particular by the fact that a plurality of winding points can be formed on the projecting winding spindle. Due to the multi-part drive shaft and its couplings can be realized particularly long projecting chuck, so that the number of wound on the circumference of the chuck coils can be significantly increased.
