Definitions

  • ABSTRACT OF THE DISCLOSURE Drive for a rotary printing press having printing presses disposed in tandem includes two main drive shaft portions connected by a coupling having an outer part fixed to one shaft portion and an inner part to the other shaft portion.
  • the outer part has inner teeth and the inner part is formed of a pair of adjacent coaxial gears having outer teeth meshing with the teeth of the outer part.
  • the gears are relatively immovable in the radial direction.
  • One of the gears is axially displaceable relative to the other gear.
  • My invention relates to drive for a rotary printing press with in-lne or tandem arrangement of printing mechanisms. More particularly, my invention relates to such a drive which includes a motor-driven main drive shaft formed of two or more portions each carrying a worm drive operatively connected with a respective one of the printing mechanisms, the individual portions of the main drive shaft being connected to one another by a forcelocked coupling located between adjacent printing mechanisms or groups of printing mechanisms.
  • a drive for multicolor rotary printing presses having a plurality of printing mechanisms arranged in a row wherein the motor-driven main drive shaft is multipartite and each printing mechanism is in turn driven by a separate rotary gear transmission as well as a worm drive operatively connected thereto.
  • the individual portions of the main drive shaft are firmly connected to one another by tension couplings. This type of coupling can be employed because the elongation or stretching of the main drive shaft portions produced by heating when operated for a relatively long period is absorbed by the rotary gear transmissions without the production of any change in the adjustment or registry of the printing mechanisms relative to one another.
  • drives for rotary printing machines are known wherein a worm drive for each printing mecha-A nism is directly mounted on the multipartite main drive shaft passing therethrough.
  • the individual portions of the main drive shaft are force-lockingly connected to one. another by claw-type clutches located between the printing mechanisms.
  • Such claw-type clutches are not free of any play. Consequently, when such claw-type clutches are used, a printing machine can barely meet the high standards of registration accuracy that is required (note German Pats. Nos. 412,159 and 1,045,425).
  • a coupling in the form of a bevel toothed coupling comprising an outer coupling member or part fixed to a stub of one of the main shaft portions and an inner coupling part fixed to a stub of the other of the main shaft portions, the outer coupling part being formed with inner bevel teeth and the inner coupling part comprising a pair of adjacent coaxial gears having bevel teeth intermeshing with the bevel teeth of the outer coupling part.
  • the pair of coaxial gears are fixed against relative movement in the radial direction thereof, and adjusting means are provided for displacing at least one of the gears in the axial direction relative to the other of the gears.
  • the bipartite gear construction of the inner coupling ⁇ part of the bevel-toothed coupling eliminates any play between the respective teeth of the parts by an adjustment of the gears so that the teeth of the one gear of the inner coupling part lies up against one of the flanks of the teeth of the outer coupling part, and the teeth of the other gear of the inner coupling part lies up against the opposite flank of the teeth of the outer coupling part.
  • the inclination of the bevel teeth is such as to balance or absorb a turning of the worm gear caused by elongation or stretching of the respective drive shaft portion by effecting a corresponding turning of the main drive shaft portion.
  • FIG. 1 is a diagrammatic longitudinal view of a multicolor offset rotary printing press having a drive according to the invention.
  • FIG. 2 is a much-enlarged, partly sectional View of a coupling having bevelled teeth forming part of the drive of FIG. 1.
  • the multicolor offset rotary printing press of FIG. 1 is provided with four printing mechanisms 1, 2, 3 and 4. These printing mechanisms are all driven through a common main drive shaft 5 by a non-illustrated drive motor suitably connected by a non-illustrated drive 'belt to the pulley 6 located at an end of the shaft S.
  • a separate worm drive 7 is associated with each of the printing mechanisms 1, 2, 3 and 4 and is formed of a respective worm 8 mounted on the shaft 5 and a corresponding worm gear 9 mounted on the lowermost shaft of the respective printing mechanisms 1, 2, 3 and 4.
  • the main drive shaft 5 is of bipartite construction; the main shaft portion 5 which is securely connected to the pulley 6 is supported in five radial bearings 10 and one axial bearing 11.
  • the toothed coupling 12 is shown in greater detail in FIG. 2.
  • the coupling outer member 15 is fixed to a stub of the main drive shaft portion 5 by means of clamping screws 13 and slot and key 14.
  • the teeth of a pair of coaxial aligned gears 17 and 18 forming the inner part 19 of the coupling 12 mesh with inner teeth 16 provided in the outer coupling member 15. Both of the coupling parts 15 and 19 have bevelled teeth.
  • the gear 17 of inner coupling part 19 is firmly mounted iby a slot and key 20 on the shaft stub of a main drive shaft portion 5".
  • the gear 17 has an elongated hub 21 extending in the direction of the main drive shaft portion 5".
  • a gear 18 is mounted by means of a slot and key 22 on the hub 21 so that it is prevented from rotating relative to the hub 21 but is however displaceable in the axial direction thereof.
  • a thread or teeth 23 meshing with an outer adjusting ring 24 are provided at the end of the hub 21.
  • the adjusting ring 24 is force-lockingly connected by a lock washer 25 with the gear 18 of the inner coupling part 19.
  • the adjusting ring 24 is iixable in a selected position relative to the gear 17 by suitably tightening a radially extending threaded pin 26.
  • the operation of the toothed coupling shown in FIG. 2 is as follows: After installing the main drive shaft 5', 5", and attaching the toothed coupling 12, the gear 18 is drawn out in the axial direction from the gear 17 of the inner coupling part 19 by the adjusting ring 24 until the teeth of the gear 17 lie up against one flank and the teeth of the gear 18 lie up against the other liank of the space between the teeth 16 of the outer coupling part 15. Thereby, any possible play in the coupling is avoided. Thereafter, the printing mechanisms 3 and 4 are suitably adjusted.
  • the worm gear 9 of the printing mechanism 3 is caused to turn slightly in contrarotating direction. This can cause inaccuracies in the lit. Such inaccuracies are avoided by providing the teeth of the toothed coupling 12 with a bevel or inclined construction so that any elongation or stretching of the main drive shaft portion 5" effects a displacement of the inner coupling part 19 relative to the outer coupling part 15 and thereby a slight rotation of the worm 8 of the printing mechanism 3. This rotation can be so great that the aforementioned undesired turning of the worm gear 9 of the printing mechanism 3 is nulliiied or balanced.
  • the toothed coupling 12 of my invention has a dual purpose: connection of the individual portions of the main drive shaft free of any play therebetween, and balancing or equalization of the slight adjustment or misalignment of the printing presses that would normally occur after relatively lengthy operation due to increase in length or stretching of the main drive shaft portions due to the heating thereof.
  • Drive for a rotary printing press with printing mechanisms disposed in tandem comprising a motor-driven main drive shaft formed of at least two shaft portions, worm drive means on each of said shaft portions operatively connected to a respective printing mechanism for driving the same, a force-locking coupling connecting said shaft portions, said coupling comprising an outer coupling part fixed to one of said shaft portions and an inner coupling part iixed to the other of said shaft portions, said outer coupling part being formed with inner bevel teeth and said inner coupling part comprising a pair of adjacent coaxial gears having bevel teeth meshable with the bevel teeth of said outer coupling part, said pair of coaxial gears being fixed against relative movement in the radial direction thereof, at least one of said gears being displaceable in the axial direction relative to the other of said gears.
  • Drive means including key and slot means for xing said other of said gears to Said respective shaft portion.
  • Device including a radially extending threaded pin carried by said adjusting ring and adjustably engageable with said hub for locking said adjusting ring against movement relative to said other of said gears.
