Definitions

  • the invention relates to a lubrication system for a control unit having rotationally symmetrical component in one Printing machine according to the preamble of the main claim.
  • a lubrication system of this type is used as a lubrication device of moving machine parts, especially in printing machines, known from DD 288 792 A5.
  • the machine elements have a lubricant sensor on the machine element is arranged.
  • This lubrication system is relatively complex and only periodically transfers the lubricant to the corresponding machine element. Especially in the case of heavier loads Machine elements is in use of such Lubrication systems cannot rule out increasing wear.
  • Lubrication is preferably carried out after a lubrication schedule, but not a subjective misconduct is to be excluded. For example, the lubrication of Lubrication points are forgotten or it becomes an unsuitable one Lubricant used or the dosage does not correspond the given order of magnitude.
  • a rotary printing press is included Drive devices of individual assemblies and with one Central lubrication of the drive devices known.
  • the drive device is a storage container as a buffer element assigned for lubricant, the reservoir being a Opening for the metered delivery of lubricant to the drive device has and the reservoir over the Central lubrication can be refilled.
  • the invention is preferred for the drive for friction rollers in an inking unit suitable.
  • the object of the invention is a lubrication system of the type mentioned at the outset to create that Avoids disadvantages, in particular a more uniform Lubrication of the control unit of a rotationally symmetrical Component allowed and that a reduction in friction and wear allowed on the elements of the control unit.
  • the task is based on the training features of the main claim solved. Further training results from the subclaims.
  • a first advantage of the lubrication system according to the invention is reasoned that this is continuously on the controls having control unit of a rotationally symmetrical Component acts. With this permanent lubrication system manual lubrication of the control unit is preferred according to the lubrication plan, lapsed and a possible subjective Misconduct is therefore excluded.
  • Another advantage is that preferably a uniform Lubricant for all control elements to be lubricated, preferably at the same time for those with circulating lubrication Bearings, the rotationally symmetrical component can be used is.
  • control elements of the control unit have a complete encapsulation. So that is in addition to the lubricant supply, noise reduction and protection against contamination can be achieved. Furthermore, with cooling this continuously effective lubrication system and anti-corrosion protection on the elements of the control unit achievable, what overall to reduce friction and wear is.
  • the lubrication system according to the invention is rotationally symmetrical Component 2, which laterally in a bearing 12 in a side frame 1 is rotatably accommodated. At least one control element 3 is stationary on the side frame 1 arranged and on the side frame 1 is a first encapsulation 8 preferably arranged in several parts. On rotationally symmetrical Component 2 is at least one control element on the end face 4 arranged, which is at a mating point with the control element 3 is engaged and forms a control unit 3, 4. On an end face of the control unit 3. 4 rotating component 2, a second encapsulation 9 is arranged.
  • the encapsulations 8, 9 have a sealing unit 10, 11 on which by a fixed seal 10 on the first Encapsulation 8 and one arranged on the second encapsulation 9 Seal 11, which is rotatable with the component 2, formed is.
  • the control unit 3, 4 is within one by the encapsulations 8, 9 formed free space 16, which of these encapsulations 8, 9, including the sealing unit 10, 11, is enclosed.
  • Feed and Return line 14, 15 are preferably part of central lubrication.
  • a multi-color rotary printing press has several printing units arranged in series for sheet processing.
  • each printing unit has a plate cylinder with at least one inking unit and possibly a dampening unit, a blanket cylinder and the sheet guiding cylinder as a double-sized printing cylinder (rotationally symmetrical component 2).
  • sheet guide cylinders are again arranged as double-sized transfer cylinders between the printing units, and a double-sized turning drum can also be used as sheet-guiding cylinder, for example according to the principle of trailing edge use as single-drum turn.
  • a rotationally symmetrical component 2 designed in this way as a sheet-guiding cylinder is in turn rotatably received in a bearing 12 in a side frame 1.
  • the rotationally symmetrical component 2 is of double size, that is to say two diametrically (by 180 ° offset) sheet-holding systems 6, 7 are arranged on the circumference.
  • the double-sized sheet guide cylinder (rotationally symmetrical Component 2) designed, for example, as a turning drum, so the bow support system 6 as a pivot shaft Gripper shaft and grippers or as gripper shaft and grippers executed itself and the sheet holding system 7 is as a with an air supply coupled suction pipe.
  • the sheet holding systems 6, 7 are two each diametrically arranged sheet holding systems 6, 7 on component 2 educated.
  • the sheet holding systems 6, 7 are each by means of roller levers 5 and role as a control element 4 coupled and the control element 4 is spring-loaded at a mating point with that on the side frame 1 arranged control curve as control element 3 a control unit 3, 4 in engagement.
  • the rotationally symmetrical component 2 as a curved guide cylinder, especially as a turning drum, it is fixed on the side frame 1 arranged control element 3 preferably on the pin or the shoulder of the component 2 arranged in a bearing 13.
  • the control element 3 is stationary to the side frame 1 axially on the pin or shoulder displaceable, e.g. for changing the operating mode (straight printing au fine and reverse printing and vice versa).
  • the sealing system 10, 11 is designed such that the stationary seal 10 and that with the rotatable component 2 connected seal 11 touching or contactless to each other secure the free space 16.
  • a non-contact sealing system 10, 11 is preferably a labyrinth seal and as contacting sealing system 10, 11 is preferably one Slip seal can be used.
  • the feed line 14 feeds the lubricant under pressure through the bearing 12 from the outside through the side frame 1 into the free space 16. If the control element 3 is accommodated in a bearing 13, the feed line 14 preferably also feeds lubricant into the free space 16 through the bearing 13. When the lubricant is supplied through the bearings 12, 13, lubricant is simultaneously supplied to the bearing points of these bearings 12, 13 via the feed line 14. During the rotational movement of the component 2, the lubricant is thrown off by centrifugal force within the free space 16 and is collected in the lower part of the encapsulations 8, 9.
  • the return line 15 is arranged at the lowest point of the encapsulation 8 and is functionally connected to a circulation system for the lubricant.
  • At least one of the encapsulations 8, 9, preferably the encapsulation 8, is formed at least in two parts.
  • Related to the Axis of component 2 encloses a lower half-shell as a part of the lower area of the free space 16 and an upper Half shell or preferably two quarter shells enclose the overhead space 16.
  • the sealing system 10, 11 is preferably circumferentially on the Encapsulations 8.9 composed of several parts.
