Definitions

  • the improvement relates to a device for the pivotable mounting of a sheet transport drum compared to a drive-side mounting.
  • a device of this type is known from DE-OS 4 012 928.
  • DE-OS 4 012 928 a sheet transport drum for skew register correction has become known. It shows that the drum body can be pivoted against the drive-side fixed bearing. For this purpose, for example, the drum body is connected to the drive-side shaft journal via a deformable disk. The disc allows the drum body to move transversely to the drum axis. However, it rigidly transmits the drive movement from the drive gear to the drum body. Since the drum body is mounted on its other side in a bearing journal with an eccentric bushing, an inclined position of the Drum body can be reached without moving the drive gear.
  • the device shown in DE-OS 4 012 928 has the disadvantage, however, that during the adjustment in the oblique direction, constraining forces can still develop on the bearing of the drive gear.
  • the aim of the invention is therefore to optimally decouple the constraining forces from the inclined position of the drum body from the bearing on the drive side. At the same time, an improved centering of the drum body compared to the drive-side fixed bearing is to be made possible.
  • the object of the invention is therefore to optimally keep the resulting forces from the inclined position of the drum body away from the drive-side mounting on a device according to the preamble of claim 1.
  • the radial and paint connections are advantageously separated from one another and in particular also decoupled from the rotary transmission. Due to the claimed design of the coupling, there can be no change in the position of the drum body in the axial direction, and furthermore the constraining forces on the drive-side bearing caused by the inclined position are considerably reduced compared to the already good initial state.
  • Fig. 1 the drive-side storage of a sheet transport drum is shown.
  • the sheet transport drum itself is not shown.
  • a drive gear 2 is mounted on its shaft journal 3.
  • the bearing 4 is fastened in a sleeve in the frame wall 1.
  • a drum body 5 of the sheet transport drum is coupled to the shaft journal 3.
  • a centering hole 6 is provided in the drum body 5 and a centering hole 7 is provided in the shaft journal 3.
  • a centering sleeve 8 is inserted into these centering bores 6, 7.
  • the centering sleeve 8 is a hollow cylindrical part which overlaps the interface between the drum body 5 and the shaft journal 3.
  • an enlargement of the bore is provided within the centering sleeve 8 so that a spacer bush 9 can be used there.
  • the spacer sleeve 9 extends beyond the centering sleeve 8 by a small amount.
  • the connection of the drum body 5 with the shaft journal 3 is made with the aid of a pull rod 10. It passes through the shaft journal 3 and the spacer bush 9 and is screwed into the drum body 5.
  • the drum body 5 is guided radially without play on the projecting outer surface of the centering sleeve 8 and is held in the axial direction without play by the pull rod 10 against the spacer bush 9.
  • the transmission of rotation of the drive torque from the anti-lift gear 2 via the shaft journal 3 to the drum body 5 is taken over by a coupling disk 11.
  • the coupling plate 11 is designed as a flat ring. It is coupled on its outer circumference with a screw 12 to the drum body 5.
  • On her inside A further screw connection 13 is provided for coupling to the shaft journal 3.
  • the screw connections 12, 13 ensure that the drive gear 2 is coupled to the drum body 5 in a play-free and precisely fitting manner in the direction of rotation of the sheet transport drum.
  • an axial or pivoting movement between the drum body 5 and the shaft journal 3 is possible to a large extent by means of the coupling disk 11.
  • the sheet transport drum is inclined to correct the register.
  • the inclination is further shown as a displacement of the axis of the drum body 5 with respect to the axis of the shaft journal 3. It is designated by the dashed line S in FIG. 1.
  • a movement is required in the region of the centering of the drum body 5 relative to the shaft journal 3.
  • 2 shows an enlarged illustration of the centering area between the shaft journal 3 and the drum body 5.
  • the centering sleeve 8 and the spacer sleeve 9 are shown in an enlarged view.
  • the centering sleeve 8 can be seen as the central element.
  • the centering sleeve 8 is firmly seated in the shaft journal 3 and is crowned at the end projecting from the shaft journal 3.
  • the centering hole 6 in the drum body 5, like the paired outer surface of the centering sleeve 8, is spherical.
  • the spherical shape of the centering hole 6 and centering sleeve 8 forms a sliding surface 14 in the contact area.
  • This sliding surface 14 is designed as an inner annular surface and chamfer 17 on the outer end face of the centering hole 6 on the drum body 5.
  • the sliding surface 14 is designed as an outer ring surface and chamfer 18 towards the end face of the centering sleeve 8 towards its end on the drum side.
  • the drum body 5 When the drum body 5 is pivoted with respect to the axis of the shaft journal 3, the drum body 5 can thus carry out a rolling motion on the outer surface of the centering sleeve 8 in the region of the sliding surface 14.
  • the radial remains Positioning between drum body 5 and shaft journal 3 is completely preserved, since the pairing of center hole 6 and centering sleeve 8 is free of play.
  • the position in the axial direction is constantly secured by the fact that the drum body 5 is secured to an end face 15 of the spacer sleeve 9 by means of the pull rod 10. This forms a quasi-punctiform support for the drum body 5 with respect to the shaft journal 3.
  • the end face 15 of the spacer bush 9 has such a small diameter that one can speak of a punctiform support.
  • the entire arrangement is very easy to assemble and inexpensive to manufacture.
  • the sheet transport drum is preassembled, as is the bearing unit of the drive gear 2.
  • Centering sleeve 8, spacer sleeve 9 and coupling plate 11 are fastened or inserted on the shaft journal 3.
  • the drum body 5 has been pushed onto the centering sleeve 8 by means of the centering hole 6, the position can be secured by means of the pull rod 10. Thereafter, only the correct connection in the direction of rotation is required by attaching the screw 12 between coupling plate 11 and drum body 5.
