Definitions

  • the invention relates to a tensioning device for tubular winding cores, in particular winding cores carrying paper webs or similar material webs, consisting of several tubular segment-shaped tensioning segments which are radially adjustable in a cage and which are arranged around a pin, between which and the tensioning segments support elements are provided, which are provided in circumferential grooves of the pin surface, the pin having an equilateral polygonal core cross section in the area of the grooves.
  • Such clamping devices are e.g. known from GB-A-917 978.
  • cylindrical rollers serve as support elements. The cylindrical rollers roll during a rotational movement exerted on the pin on the one hand on the base of the circumferential grooves of the pin and on the other hand on the tubular inner circumferential surface of the clamping segments, as a result of which the clamping segments are moved radially outwards into the clamping position or inwards back into the starting position.
  • the object of the invention is now to improve the generic tensioning device in such a way that the wear on the mutually movable parts is reduced.
  • the support elements on their side facing the tensioning segments are spherical and are inserted in correspondingly hemispherical recesses in the inner surfaces of the tensioning segments and on the side facing the pin one adapted to the cross-sectional shape of the base of the groove Have contact area.
  • the support elements Due to the inventive design of the support elements, a flat contact is achieved at the points of contact of the support elements with the clamping segments on the one hand and the support elements with the pin on the other hand.
  • the mutually movable parts, clamping segments, support elements and pins do not have a linear contact as in the known clamping device, but rather a flat one, so that the surface pressure is lower and wear is reduced.
  • the design of the tensioning device according to the invention makes it possible to enlarge the core cross section of the pin and thus to increase its resilience. This is also the purpose of the preferred, in cross-section, convex curvature of the base of the circumferential grooves in the pin, which leads to an enlargement of the core cross-section of the pin.
  • the concave shape of the base of the circumferential grooves as seen in their longitudinal section, provided according to a further advantageous embodiment of the tensioning device according to the invention, prevents a notch effect which can occur in the case of sharp-edged transitions in the grooves, and leads to an increase in the accuracy of fit or allows compensation for smaller manufacturing inaccuracies to.
  • the support elements used in hemispherical recesses in the tensioning segments always support the tensioning segment at the same point even when the pin is rotated, so that it is not tilted as easily as if, as in the known tensioning device, the support element also turns with respect to the tensioning segment when the pin rotates can shift.
  • the tilting mobility of the clamping segment is fully preserved due to the ball joint-like connection with the support element relative to the pin.
  • the clamping device consists of the flange screws 1, the ring spring 2, the end ring 3, the tubular segment-shaped clamping segments 5 provided with a serrated or grooved outer surface 4, the support elements 6, the pin 7, the further ring spring 8, the cage 9 , the end cover 10, which is firmly connected by the screw 11 to the pin 7 and secures the axial position of the parts pushed over the pin 7.
  • the base 12 of the circumferential grooves 13 in the pin 7 is concave in accordance with FIG. 2. Accordingly, the surface of the support elements 6 opposite the pin 7 is formed in a circular arc with the radius r 2 (FIG. 4). Seen in the cross section of FIG. 1, the circumferential grooves 13 are convexly curved. The remaining core cross section of the pin 7 can be seen in FIG. 1 by the oblique hatching. Corresponding to the convex arch shape of the base 12 of the groove 13 in the cross section of FIG. 1, the surface of the support element 6 opposite the pin 7 is formed with the radius r 3 (FIG. 3). In this embodiment, the support elements 6 lie flat on the base 12 of the circumferential grooves 13 in the pin 7, as can be seen from FIGS. 1 and 2.
  • the clamping segments 5 are provided with hemispherical depressions 14, in which the support elements 6 also lie flat with their spherical surface with the radius r. In this way, support element 6 and clamping segment 5 form a ball-and-socket connection, which give the clamping segment 5 a certain degree of tilting about the axis of the pin 7.
  • the tensioning device is assembled in such a way that the tensioning segments 5 are placed on the pins 7 with the interposition of the support elements 6 in the grooves 13 of the pin 7 or depressions 14 in the tensioning segments 5 and fixed in the radial direction by the ring springs 2 and 8 will.
  • the cage 9 is then pushed over the pin 7 and attached to the pin 7 via the cover 10 and by means of the screw 11.
