Definitions
- the invention relates to a reel spool having two lateral flange disks, between which a winding core is arranged, and in which the flange disks are releasably connected to the winding core by a centrally arranged pull rod.
- the winding reel in question is seen in terms of dimensions as a large-capacity reel spool.
- the side flange washers are made of steel.
- a threaded rod is usually used which has an eyelet at one end in order to transport the winding reel by means of a hoist. At the opposite end is on the
- the lateral flange discs are conical or cone-shaped, so that a corresponding deformation of a steel plate is necessary for their design.
- a paragraph for example in the form of a bead, a recess or the like is also attached, which receives the hub connecting the two flanges.
- the weight is correspondingly high, resulting in correspondingly high transport costs.
- This version is also suitable for medium and small winding spools.
- the invention has the object of providing such a reel spool, in particular a large-capacity reel spool of the kind described in more detail above, that it is cheaper to produce, that the weight is reduced compared to the known designs and that accordingly the transport costs can be reduced accordingly.
- the force introduction body are provided with holes through which the pull rod is guided.
- the pressure forces generated by the eyelet and the opposite nut are now transmitted via the force introduction body on the flange discs. This reduces the surface pressure to a value allowed for plastics.
- the weight of the reel spool is significantly reduced compared to the steel construction.
- the winding bobbin shown is designed as a biconical winding bobbin.
- the reel spool can also be equipped with flat or approximately flat-shaped flange discs, or with concave or convex-shaped flange discs.
- the force introduction body is arranged circumferentially, ie, the outer end faces of the lateral flange discs are annularly contacted, ie, each flange is a rotationally symmetrical body.
- Each flange can be produced particularly economically if the force introduction body forms a one-piece plastic molding with the flange disc.
- the shaped body in cross-section is designed parabolic or V-shaped, wherein the center of curvature or the tip in the middle of the bore for passing through the tie rod lie.
- the walls can be arched against the parabola.
- the molded body is attached or formed approximately at the level of the outer circumference of the winding core to the flange. Each shaped body then extends outward, ie, to the side facing away from the winding core.
- the shaped body could also be referred to as a bulge.
- FIG. 1 shows an embodiment of the winding bobbin according to the invention in a sectional view.
- the winding bobbin 10 shown in FIG. 1 consists of two lateral flange disks 11, 12 made of a plastic, which are designed as cones.
- the two flange disks 11, 12 are provided with two central through-holes 13, through which a pull rod in the form of a threaded rod 14 is guided.
- two nuts 15, 16 are screwed. Contrary to the illustration, one of the nuts 15 or 16 could be replaced by an eyelet.
- At the opposite outer sides of the flange discs 11, 12 are two force introduction body 17, 18 formed, so that from the two flange discs 11, 12 and the force introduction bodies 17, 18 integral plastic moldings have been formed.
- the force introduction bodies 17, 18 form the middle regions of the flange disks 11, 12.
- the force introduction bodies 17, 18 are formed as rotationally symmetrical shaped bodies and are approximately parabolic in cross section.
- the centers of curvature of the parabolic or approximately parabolic force introduction body are in the middle of the holes.
- the two legs extend arcuately, so that these moldings can also be U-shaped or V-shaped and rotationally symmetrical.
- the power leitimgsêt 17, 18 are attached approximately at the level of the peripheral surface of the winding core to the flange discs 11, 12 and then extend in the sense of a bulge in opposite directions.
- the lateral flange disks 11, 12 are provided adjacent to the peripheral surface of the winding core with circumferential depressions, shoulders and / or beads 19, 20.
- the flange discs 11, 12 may also be designed angular.
- the winding core 21 can also be designed angularly, wherein a combination with round flange washers or a round winding core 21 is possible.
- the invention is not limited to the illustrated embodiment. It is essential that at the opposite outer sides of the made of plastic flange washers 11, 12 force introduction body 17, 18 are formed or attached, which transmit the force applied when tightening the nut pressure forces on the flange discs 11, 12.
- the flange discs 11, 12 and the force introduction body 17, 18 integral plastic moldings.
