Definitions

  • the invention relates to a device for the frictional coupling of a fixed gear and, in contrast, in the rotational position adjustable gear on a cylinder of a turning device in a sheet-fed rotary printing press with features according to the preamble of claim 1.
  • the invention also relates to the formation of an electrical fuse of such a device to avoid the Commissioning of a machine that is not ready for operation.
  • a device for the frictional coupling of the fixed gear and an adjusting gear for adjusting the rotational position of both gears is known from DE-OS 36 11 325.
  • a clamping disk with its edge acts as an abutment for pressure levers distributed over the circumference, which at one end press the adjusting gear against an annular shoulder recess in the fixed gear, and whose other inward ends are loaded with the spring force of a centrally arranged tensioning element, wherein the abutment is moved far outwards to achieve an optimal leverage so that the greatest possible torque can be absorbed by the frictional coupling caused by the friction of the contacting surfaces of the two gear wheels. Large torques require very high clamping forces.
  • the adjusting member can be adjusted by means of a thread in a way which has a first section in which the spring force acting on the pressure levers increases from a low to a value required to maintain the relative rotational position in the known arrangement , and comprises a second section in which the spring force required to maintain the relative rotational position is maintained, so that the rotary printing press can only be put into operation if there is a sufficiently tight coupling between the fixed gear and the adjusting gear.
  • the supply circuit of the drive device is first interrupted and only then is the coupling forces reduced.
  • a comparable coupling is known from JP-A-58-78763, in which the adjusting gear for coupling is also pressed into an annular shoulder recess of the fixed gear.
  • four clamping segments are distributed around the circumference, each of which is tightened by a draw bolt with a thread, and a gear is provided for rotating the nut thread for these draw bolts, which consists of two coaxially arranged worms and four worm wheels, which with their teeth in pairs of engage on opposite sides in the toothing of the two screws. Both screws can be rotated by a common crank via a bevel gear.
  • the worm gear requires several crank revolutions, including for the actuation of the phase adjustment of the adjusting gear in relation to the fixed gear. A electrical protection of the coupling in the operating position is not provided.
  • the object of the invention is to provide a device that can be electrically secured in the operating position with the features mentioned at the outset in such a way that higher torques can be transmitted at lower clamping forces than previously in an inexpensive construction, and this is preferably made possible with only one clamping screw.
  • the invention solves this problem by the training features according to the characterizing part of patent claim 1.
  • An essential feature of this training is the increase in the frictional force by increasing the number of effective friction surfaces. This is preferably achieved by friction elements from mutually and lamellar interlocking friction disks on the fixed gear and on the adjusting gear according to claim 2, whereby the overall friction force is considerably increased. Assuming a constant coefficient of friction, the clamping force for the frictional coupling of the fixed gear and the adjusting gear can be reduced. Conversely, this design enables a substantial increase in the torque that can be transmitted by the clutch, while the clamping force remains the same, which results in considerable advantages with regard to safe operating conditions, especially in the case of high-speed printing presses.
  • the clamping device can be made from a single, centrally arranged clamping element, in particular from a threaded bolt with an external screw head, exist, the thread of which can be screwed into a nut thread, which is located centrally in the axis of the cylinder of the turning device.
  • This one clamping screw creates advantageous conditions for the arrangement of electrical means for securing the effective coupling of the gears.
  • these electrical means are designed with the features according to the characterizing part of claim 12.
  • the training features are provided according to claim 14.
  • Embodiments of the invention are partly shown schematically in the drawing.
  • Both exemplary embodiments show the arrangement of the fixed gear 1 at one end of the shaft 2 of a cylinder of the turning device of a sheet-fed rotary printing press, which is not shown in the drawing for the sake of a better overview, for the optional face printing or perfecting.
  • the fixed gear is screwed coaxially to the shaft 2 by screws 3 with the end face of the shaft 2.
  • a pin extension 4 is formed by an angular recess in the sectional view, on which the ring-shaped adjusting gear 5, which can be coupled by clamping to the fixed gear 1, is arranged so as to be adjustable in the angle of rotation.
  • This frictional coupling of the adjusting gear 5 with the fixed gear 1 is carried out by a clamping plate 6, which forms the clamping body, and by a clamping screw 7, which passes through a central bore of the clamping plate 6, is supported with the screw head 8 against the clamping plate 6 and with its bolt thread can be screwed into a nut thread in a bore in shaft 2.
  • a clamping plate 6 which forms the clamping body, and by a clamping screw 7, which passes through a central bore of the clamping plate 6, is supported with the screw head 8 against the clamping plate 6 and with its bolt thread can be screwed into a nut thread in a bore in shaft 2.
  • Is on the inside of the clamping plate 6 an integrally formed pressure ring 9 is formed, by which the adjusting gear 5 is pressed against the fixed gear 1 when the clamping screw 7 is tightened, so that both gear wheels are frictionally connected to one another by frictional forces.
  • the front contact surfaces of both gears are effective.
  • additional friction elements are provided and connected alternately to one of the two gears, these friction elements interlocking in the manner of a multi-plate clutch and in the overlap area by the clamping plate 6 via the pressure ring 9, which is supported against an external friction element, also be firmly pressed together.
  • the exemplary embodiments show friction elements made of friction disks 10 and 11, which are fastened either to the fixed gear 1 or to the adjusting gear 5 by means of screws 12 and 13 and mesh with one another in the manner of lamellas, so that an overlap area is created behind the pressure ring 9.
  • FIG. 1 shows two friction disks 10, which are fastened by means of screws 12 to the end face of the pin extension 4, and a further friction disk 11, which is fastened by means of screws 13 to the side face of the adjusting gear 5.
  • the height differences caused by the material thicknesses in the axial direction of the shaft 2 are compensated for by washers, intermediate rings 14 or other elements.
  • the inner edge of the friction plate 11 engages like a lamella between the outer edges of the friction plates 10, so that three additional annular friction surfaces are thereby formed, by means of which the transferable friction forces can be increased.
  • a further increase in the friction surfaces can be achieved, for example, by a packet-like arrangement of the friction disks, such as that shown in FIG Figure 2 is shown.
  • an elastically deformable design is provided in the direction of the axis of the shaft 2, which provides as little resistance as possible to the clamping forces exerted by the pressure ring 9.
  • This can be achieved by an elastically deformable material and, if necessary, supported by the fact that the friction disks in the overlap region and possibly also have radial incisions or cutouts through which tongues are formed, which can be deformed more easily in the axial direction of the shaft 2, as can be done can be seen, for example, from the illustration in FIG.
  • At least the friction disks fastened to the adjusting gear 5 or to the fixed gear 1 are of split design, so that separately mountable segments are created.
  • the friction disks 11 fastened to the adjusting gear wheel 5 are advantageously composed of segments which are pushed from the outside between the friction disks 10 after they have already been firmly mounted.
  • a non-positive connection can also be provided.
  • the assembly and disassembly of the friction disks can be facilitated by assembling the friction disks and intermediate rings into packages by means of intermediate layers, e.g. are glued together so that only a part is to be assembled, either in the form of a ring or as a ring segment, as explained above.
  • the means for electrically securing the effective coupling between the fixed gear 1 and the adjusting gear 5 consist of a switching ring 15 which is arranged on the clamping screw 7 in a rotationally fixed manner and of switching plates 16 which are guided on the clamping plate 6 in a radially movable manner and which the switching ring 15 releases when the clamping between the fixed gear is released 1 and the adjusting gear 5 moves radially and thereby acts with an arc-shaped contact surface 17 on an electrical switch 18 which is arranged in the supply circuit of the machine.
  • the circuit board 16 is composed of four quarter-circle segments, two of which are diametrically opposite to the axis of the clamping screw 7 and interact in pairs, so that they move in the same direction either together outwards or together inwards to the center of the clamping screw 7. These elements of the electrical protection are shown in the drawing in FIGS. 4 and 5, but the clamping screw 7 is covered by the screw head 8.
  • Each segment of the switching plate 16 has a cam 19 on the inner ring surface, which cooperates with a complementarily shaped curve 20 on the switching ring 15.
  • the cams and curves of the one pair of segments of the circuit board 16 are to the cams and curves of the other pair of segments of the circuit board 16 both axially offset and radially offset by 90 degrees to each other.
  • the segments of the circuit board 16 are guided by screws 22 which pass through radially directed slots in the segments of the circuit board.
  • the segmentation of the circuit board 16 and the paired interaction of the segments is achieved constructively in that the cams 19a of one pair of segments are formed on the front of the segments and the cams 19b of the other pair on the back of the segments of the circuit board, as is apparent from the Representation in Figures 4, 4a, 5 and 5a results.
  • a clamping screw rotation of more than 90 degrees is thereby achieved by opening the switch 18 in the drive circuit of the machine.
  • a stop pin 23 connected to the switching ring 15, which interacts with stops 24 on screws for guiding and holding the one pair of segments and limits the opening angle of the clamping screw 7 from one stop position to the other stop position to approximately 160 degrees.
