Definitions

  • the invention relates to a device for releasably coupling a gear ring on a gear body.
  • DE 41 41 817 C2 describes a device for coupling a gear ring known with a main gear.
  • the gear ring is by means of a Clamping ring and several spring-loaded bolts on the main gear over Friction fixed.
  • the spring assemblies Biased load on the clamping ring so that the gear ring is freely rotatable.
  • the gear parts with the gear ring or the main gear are connected, are rotated relative to each other. This is for example is required to print units accordingly in sheet-fed rotary printing presses to adjust a sheet format in the circumferential direction relative to each other.
  • An application is the conversion of a press for sheet turning for the so-called perfecting.
  • the problem with the device is that the clamping is generated via the clamping ring and the gear ring. Are there there are several friction surfaces, the friction behavior of which can be different. When releasing the gear clamp, there may be different conditions come.
  • a certain game is available. In special situations, e.g. With overload, this game can cause an offset between gear ring and main gear so that the clamping is not at the prescribed Position is maintained. In addition, damage can result from the Possibility of this offset coming.
  • the device for coupling the double gear must not be used as a weak point in the drive in the event of high load breakages or tend to make adjustments.
  • the object of the invention is therefore in a device according to the preamble of Claim 1, both easy to solve, and at the same time torsionally rigid connection between the elements generating the clamping and to introduce the cylinder journal.
  • a gear ring 5 Coaxial with the main gear 4 a gear ring 5 is arranged.
  • the gear ring 5 sits on a collar 6 of the Gear flange 3.
  • a clamping ring 7 Coaxial to the main gear is a clamping ring 7 arranged, which rests on an end face 8 of the gear ring 5.
  • the driving Unit of the double gear is manufactured in that tie rods 9, which pass through the main gear 4, the gear flange 3 and the clamping ring 7, be sprung against the clamping ring 7.
  • the tie rods 9 are for this purpose a spring assembly 10 loaded.
  • a clutch 11 To release the connection clamped in the normal state is on the inside the main gear 4 to the machine wall 2 towards a clutch 11 is provided. It is placed in a ring around the cylinder pin 1 and on the machine wall 2 held.
  • the separating clutch 11 is in several parts, such that they are in can extend in the axial direction. The axial expansion movement is used for decoupling of the double gear.
  • the separating clutch 11 has a gripping ring surface 12 on, which is oriented axially parallel. This gripping ring surface 12 cooperates a counter ring 13, which is provided on the main gear 4, together.
  • Farther is an axial bearing 14 is provided on the clutch 11, the extends between an end face of the clutch 11 and a pressure ring 15.
  • the pressure ring 15 forms a support for the spring assemblies 10 and is with the Tie rods 9 connected.
  • the axial extension of the clutch 11 enlarged so that the axial bearing 14 acts on the pressure ring 15 and the Spring packs 10 compressed. This releases the tie rods 9 somewhat, the effect on the clamping ring 7 is canceled and the clamping of the Gear ring 5 by means of the clamping ring 7 is released.
  • clamping ring 7 and main gear 4 there may be relative movement between the gear ring 5, clamping ring 7 and main gear 4 come. Due to the relatively undefined friction conditions it is not ensured that, for example, only the gear ring 5 within the clamping pair between clamping ring 7 and main gear 4 slips through. Rather, the clamping ring 7 can also be taken along. There here a game between the clamping ring 7 and the tie rods 9, or between the gear flange 3 and the tie rods 9 is present, can be a handsome Relative movement of the clamping ring 7 come about, which leads to clutch damage can lead.
  • Coupling disk 16 connects the clamping ring 7, and the gear flange 3 and the cylinder pin 1 with each other. She is one of them connected to the gear flange 3 via support points 17. Against the tie rods 9 quasi through the play-free connection via the coupling disk 16 decoupled from circumferential driving forces.
  • the coupling plate 16 can also be used to support the clamping or the release of the clamping.
  • the coupling disk 16 in the form of a plate spring in such a way that it either supports the clamping force of the clamping ring 7 against the gear 5 or that it applies a releasing force to the clamping ring 7 against the clamping force.
  • the slight disadvantage that the clamping force of the tie rods 9 is then slightly reduced is offset by a defined release force when the clutch is disconnected. This makes the way of working safer and more precise.
  • the height of the support points 17 can also be such that the coupling disk 16 in the idle state either pulls the clamping ring 7 against the gear ring 5 or pushes the clamping ring 7 away from the gear ring 5. This would also result in a preload of the clamping ring 7 in the clamping or releasing direction.
