Definitions

  • the invention relates to a device for adjusting the relative rotational position between a gearwheel and a gear rim which is concentric therewith and rotatably arranged on an annular shoulder of the gearwheel, with radially arranged pressure levers which can be actuated jointly by an axially adjustable, centrally arranged adjustment process and by means of which a spring force is used to achieve this non-positive connection of adjoining end faces of the gear wheel and ring gear can be released by reducing the spring force acting on these end faces.
  • a coupling device has become known (JP 58-71162), in which a non-positive connection between the ring gear and the gearwheel is achieved with the aid of a plurality of clamping elements arranged in the vicinity of the circumference, which can be released from a centrally arranged screw via levers.
  • These levers are pivotally mounted on pins and have screw connections by means of which the adjustment movement of the central screw is transmitted to the coupling parts.
  • the known devices have the disadvantage that the printing machine can also be started up if, after the changeover, the ring gear is not firmly connected to the gear again. As a result, the relative rotational position between the ring gear and the gearwheel can be adjusted during operation of the printing press, which can result in damage to the printing press.
  • the object of the invention is to propose a generic device, which ensures a safe coupling between the gear and ring gear during operation of a printing press equipped therewith with the least possible manufacturing and assembly effort.
  • the device according to the invention has the advantage that an adjustment of the relative rotational position between the gear and the ring gear is possible with little effort. This simplifies the operation of the printing press. This ease of operation increases the security against incorrect operation.
  • the adjusting member is movable within a path which comprises a first section in which the spring force acting on the coupling elements increases from a low value to a value required to maintain the relative rotational position, and a second section in which the required to maintain the relative rotational position Spring force is at least maintained and in which an electrical switch can be actuated, which is arranged in the supply circuit of a drive device.
  • the pressure levers are loosely inserted between the annular shoulder and a tensioning disk in the radial lever guiding the pressure lever and are pivotally supported on one of these two parts in a first bearing area located between the ends of the respective pressure lever on its outer contour.
  • One design option is that in each case second contact areas of the pressure levers rest on an end face of the toothed ring facing away from the gearwheel and that third contact areas of the pressure levers, which are connected to the
  • the first support areas form longer lever arms than the second, in the area near the axis the gearwheel can be acted on by a compression spring with an axially directed force and that the axially movable, threaded actuator performs a movement independent of the compression spring within a first part of the adjustment path and within a second part of the adjustment span the compression spring.
  • This configuration has the advantage that only a compression spring is required, which can be put together in a suitable manner from plate springs, and that the adjusting member covers the path required for actuating the switch without load.
  • Another possible embodiment of the invention is to be seen in that the sprocket is clamped between the tooth edge and the clamping plate by a plurality of resilient clamping elements connecting the gearwheel and the clamping plate, such that the pressure levers with their short lever arms each formed between a first and a second contact area between the gear and the tensioning disk are mounted so that they release the tensioning disk from the ring gear by the force acting on the third contact area in each case against the spring force of the tensioning elements.
  • This embodiment of the device according to the invention also has the advantage that the adjusting member can be easily rotated within the path required for actuating the electrical switch.
  • a further advantageous embodiment of the invention is that the pressure levers which can be acted upon by an axially directed force in the region of the gear wheel near the axis and which act between the form the first and the second support areas a long lever arm, are elastically deformable and that the adjusting member causes a deformation of the pressure lever within the path provided for the adjustment.
  • This embodiment of the invention requires very few components and is therefore particularly simple to manufacture.
  • the adjusting element consists of a sleeve with an external and an internal thread, that the adjusting element is mounted in a central threaded bore of the tensioning rail and that a screw which interacts with the internal thread of the sleeve is mounted axially displaceably but non-rotatably, and that the third contact areas of the pressure levers bear against the contact surface of the head of the screw and that the pitches of the external and internal threads differ slightly from one another.
  • This development advantageously creates a path of the adjusting member required for actuating the switch.
  • a tooth edge 1 is arranged at one end of a shaft 4.
  • Bearings of the shaft 4, a turning drum carried by the shaft 4 and further parts of a printing press are not shown since they are not necessary to explain the invention.
  • the gear 1 is held on the shaft 4 with a plurality of screws, of which only one screw 5 is shown.
  • a ring gear 2 is rotatably mounted on an annular shoulder 3 of the gear 1.
  • a tensioning disk 7 is fastened with screws 6, which has six radial grooves 8 on the side facing the gearwheel 1, each receiving a pressure lever 9 which also extends radially.
  • a first contact area 10 for support against the tensioning disk 7 a second contact area 11 located on the outer lever end for transmitting the clamping force to the ring gear 2 and a contact area 12 located on the inner lever end for introducing the lever force.
  • the lever arm formed between the support areas 10 and 12 is significantly larger than the lever arm formed by the support areas 10 and 11, so that the ring gear 2 by applying a relatively small force to the pressure levers 9 on the support areas 12 with a relatively large force between the pressure levers 9 and the gear 1 is clamped, whereby a non-positive coupling between the ring gear 2 and the gear 1 takes place.
  • a pin 13 is screwed into the center of the end face of the shaft 4 and has several sections in the longitudinal direction.
  • a first section 14 has a hexagon for screwing in the pin, which at the same time serves as an abutment for a compression spring 15, which takes up a second section 16 of the pin 13.
  • the compression spring 15 consists of disc springs which are assembled in a manner known per se in such a way that a suitable spring travel results with a suitable spring constant.
  • the disc 17 transmits the force of the compression spring 15 to the support areas 12 of the pressure lever 9. The clamping thus achieved between the gear 1 and the ring gear 2 is sufficient to prevent the ring gear 2 from rotating with respect to the gear 1 in all operating states of the printing press.
  • a fourth section 20 of the pin 13 is provided with a thread onto which a threaded sleeve 21 is screwed as an adjusting member.
  • the threaded sleeve 21 is provided with a hexagon 22 and can thus be moved from the position shown with the aid of a corresponding key screwed towards the spring.
  • this has an annular groove 23 in which a stop 24 engages.
  • a lever 26 engages in a further annular groove 25 of the threaded sleeve 21.
  • the lever 26 is fixed at 27 and is pressed against a stop 29 by means of a spring 28. In this position, the lever 26 releases the confirmation element 30 of an electrical switch 31.
  • the electrical switch 31 is accordingly connected to an electrical control (not shown) of the printing press in such a way that the machine can be operated in the position shown in FIG. 1.
  • Fig. 2 shows a section through the same embodiment - but in a different operating state, in which namely the ring gear 2 can be rotated relative to the gear 1 for the purpose of converting the machine.
  • the threaded sleeve 21 is screwed further onto the pin 13.
  • the lever 26 is moved and the electrical switch 31 is thus actuated.
  • the power supply to the drive of the printing press is interrupted, so that the printing press cannot be started up before the coupling force acting between the ring gear 2 and the gear 1 is reduced.
  • the device shown in Figures 1 to 3 not only fulfills this safety function, but also enables adjustment with a few simple steps and with little effort.
  • the pressure levers 9 and the thrust bearing 17, 18, 19 designed as a roller bearing essentially contribute to the low expenditure of force.
  • Fig. 3 shows a plan view of the first embodiment.
  • the pressure levers 9 are only partially visible from the outside through an annular gap between the tensioning disk 7 and the ring gear 2. Otherwise they are shown in dashed lines.
  • a gearwheel 41 which is designed similarly to the first exemplary embodiment, is fastened on the end face on the shaft 4 by means of screws 5.
  • the ring gear 2 is also rotatably mounted on an annular shoulder 42 of the gear 41.
  • the clamping disk 43 is not rigidly connected to the gear 41, but is pressed by a plurality of clamping elements 44 distributed around the circumference onto a shoulder 45 of the ring gear 2, which in turn rests on the gear 41 at 46. This ensures a frictional coupling of the ring gear 2 with the gear 41.
  • the clamping elements 44 each consist of a screw, the head 48 of which is disc-shaped and serves as an abutment for a compression spring 49 composed of disc springs.
  • Corresponding cutouts 50 are provided in the gearwheel 41 for the compression springs 49 and the screw heads 48 of the clamping elements 44.
  • a nut 51 is tightened so far that the compression spring 49 has the required bias.
  • the nut 51 is fixed by a lock nut 52.
  • radial pressure levers 53 are provided, which are inserted into corresponding radial grooves 88 of the tensioning disk 43 and each have a bearing area 54, 55, 56 against the gear 41, the tensioning disk 43 and support a pressure ring 61 arranged centrally in the tensioning disk 43, which together with a roller cage located between the pressure ring 61 and the pressure flange 64 forms an axial thrust bearing.
  • the gearwheel 41 is provided with hardened support plates 57, which are held by screws 58, and the tensioning disk 43 is provided with hardened threaded pins 59.
  • the latter also serve to adjust the pressure levers 53 in the sense of a uniform distribution of the forces to be transmitted by them over the entire circumference of the device.
  • the axial pressure bearing 61, 64 can be moved in the direction of the pressure lever 53 with a centrally arranged screw 60, which is mounted in a corresponding thread of the tensioning disk 43.
  • the screw 60 can initially cover a path which does not yet exert any pressure on the pressure lever 53, but within which the actuating lever 26 is moved. So before that Coupling force is reduced, the drive power supply is switched off. If the screw 60 strikes the pressure flange 64, the latter will rotate with the screw relative to the pressure ring 61.
  • the axial thrust bearing provided with a roller cage ensures that the friction to be overcome for turning the screw 60 essentially consists only of the thread friction of this screw.
  • a plurality of coil springs 62 are arranged in a circle around the screw 60 in corresponding bores of the tensioning disk 43. These are designed so that they exert a certain preload on the thrust bearing 61, 64 even when there is no contact between the screw 60 and the pressure flange 64 and thus hold the pressure lever 53 in a defined position.
  • FIG. 5 shows a top view of the arrangement according to FIG. 4. Some parts that are not visible per se from a top view are drawn with dashed lines.
  • Fig. 6 shows a third embodiment in which the pressure levers also serve as spring elements.
  • the tensioning disk 72 is fixedly connected to a gearwheel 71 in a manner similar to the exemplary embodiment according to FIG.
  • the tensioning disk 72 is firmly screwed to the gear 71 and has radial grooves 74 through which pressure levers 75 are guided, which, with their short lever arm formed between the bearing areas 76 and 77, bring about a non-positive coupling of the ring gear 2 with the gear 71 , when - as shown in the figure - the bearing area 78 of the long lever arm is loaded with a corresponding force.
  • This load is based on a screw 79, which is secured with an arrangement 80, which is only shown schematically, to prevent it from being mistaken.
  • the shaft of the screw 79 is mounted in a sleeve 81 which is provided with an external as well as an internal thread and serves as an adjusting element.
  • the sleeve 81 can be rotated via a hexagon screw head 82.
  • the external thread of this sleeve has a slightly larger pitch than its internal thread with the same direction of pitch. An axial adjustment of the screw 79 by the difference in pitch in the respective adjustment direction of the sleeve is thus achieved per revolution of the sleeve 81.
  • the sleeve 81 is provided with a circumferential groove 83, in which the lever 26 engages in order to actuate the electrical switch 31.
  • a fixed stop 84 and a counterpart 85 are provided on the sleeve 81.
  • a pin 86 which is provided with a thread and is screwed into the support plate, is loosely inserted through a bore 87 in each pressure lever 75 and serves to guide the pressure lever 75.
  • the electrical switch 31 is closed, so that the machine can be started because the clutch between the ring gear 2 and the gear 71 is closed with the required force.
  • the sleeve 81 is screwed into the tensioning disk. It travels a relatively large distance, so that the lever 26 and thus the electrical switch 31 are actuated at the beginning of the path.
  • the screw 79 has only covered a small distance, with what the resilient pressure levers 75 are somewhat relaxed, but the pressure they exert on the ring gear 2 is still sufficient to hold the ring gear in place. Only when the sleeve 81 is turned further are the pressure levers 75 relaxed to such an extent that the ring gear 2 can be rotated on the gear 71.
