Definitions
- the invention relates to a winding machine for winding a yarn sheet to a plurality of coils according to the preamble of claim 1.
- the filaments of a spinning position are co-wound in parallel with spools.
- the known winding machines are used, each having a winding position per thread, wherein the winding points extend parallel along a winding spindle.
- the winding spindle is arranged cantilevered on a spindle carrier, so that the wound on the circumference of the winding spindle coils are ready to be removed at a free end.
- the winding spindle has a chuck, on whose circumference a clamping device for receiving winding tubes is arranged.
- the chuck is hollow cylindrical to a drive side and connected via a hub to a drive shaft.
- the drive shaft is designed in several parts and executed by a rear bearing shaft and a front bearing shaft.
- the rear bearing shaft is designed with a free end with a drive detachable.
- the front bearing shaft is connected with a free end to the hub of the chuck.
- a hollow carrier projects into the open end of the chuck, wherein a bearing of the front bearing shaft is formed in the interior of the hollow carrier.
- the bearing of the front bearing shaft has two rolling bearings, which are arranged between the bearing shaft and an inner bearing sleeve.
- the inner bearing sleeve is inserted in an outer bearing sleeve, wherein a plurality of rubber elements are provided for damping between the two bearing sleeves.
- a plurality of rubber elements are provided for damping between the two bearing sleeves.
- further damping elements between the outer bearing sleeve and the hollow beam are arranged. As damping elements while O-rings are used.
- the known winding spindle requires an increased space requirement, so that larger lengths can only be realized with larger diameter chuck diameters.
- the O-rings used as damping elements have the disadvantage that the damping cross-section is tolerated relatively coarse. So the receiving grooves in the bearing sleeves must be tolerated accordingly large to avoid unwanted incompressibilities. However, this has a disadvantageous effect on the damping behavior of the rubber elements. In addition, the grooves affect the skill of the components of the winding spindle.
- a winding machine with a winding spindle is known in which the chuck is driven by a one-piece drive shaft which is mounted multiple times within a hollow carrier.
- a sleeve package is provided, which is arranged on the outer diameter or on the inner diameter of the hollow carrier.
- the sleeves are movable within the sleeve stack relative to each other to counteract vibrations of the hollow carrier by internal friction.
- Such oscillations also require a considerable additional installation space, which is either at the expense of strength or at the expense of large diameters of the chuck.
- the diameters of the chuck are predetermined due to the Spulhülsen and not freely selectable.
- Another object of the invention is to form a winding machine with a winding spindle, the chuck can be used across several critical speeds. This object is achieved in that between the front bearing shaft and the hollow support is provided outside the storage axially staggered additional damping means.
- the invention is based on the fact that damping can only be particularly effective at the points at which the articulation points acting on a damping means can perform relative movements relative to each other.
- the installation space between the front bearing shaft and the hollow body is used directly to dampen vibrations of the coupled with the chuck front bearing shaft.
- Another advantage of the invention is that substantially no additional installation space is required to integrate the damping means between the bearing shaft and the hollow beam. There is no additional radial installation space required.
- the development of the invention is particularly advantageous in which the damping means is arranged in a shaft portion between the bearing and an end of the front bearing shaft connected to the chuck.
- the positioning of the damping means in the vicinity of the connection point to the chuck shows a high attenuation both at critical winding speeds in the lower and at critical winding speeds in the upper region.
- the development of the invention is carried out Favor, in which the damping means is formed by a held on the circumference of the front bearing shaft damping bearing. It is essential that the damping bearing of the weight and weight of the chuck remains almost unloaded. Only when driving through resonances is the damping bearing active.
- the damping bearing is preferably formed from a rolling bearing and a damping element which is supported on an outer ring of the rolling bearing.
- the rolling bearing forms the outgoing from the rotating bearing shaft articulation point for the damping element.
- a damping ring is preferably formed with an inner sleeve and an inner sleeve with clearance surrounding outer sleeve, wherein the inner sleeve and the outer sleeve are elastically connected to each other by a rubber element.
- the installation space is independent of the respective rubber element and solely on the diameters of the inner sleeve and outer sleeve dependent.
- the spring characteristic of the rubber element between the inner sleeve and the outer sleeve can therefore be formed before installation with predetermined damping characteristics.
- the damping ring can be formed such that a width of the inner sleeve is smaller, equal to or greater than a width of the outer sleeve. This can be influenced in particular the mobility of the sleeves to each other.
- the rolling bearing is formed by two spindle bearings, which are arranged in an O-arrangement side by side on the front bearing shaft. Thus, the damping bearing remains without influence on the adjacent bearing of the front bearing shaft.
- the bearing of the front bearing shaft is formed by two rolling bearing units arranged at a distance from each other, wherein the rolling bearing units are arranged within a bearing bush and wherein the bearing bushing over several the damping rings is held within the hollow carrier.
