Definitions
- the invention relates to a device for eliminating drive play in one Printing unit according to the preamble of claim 1.
- the aim of the invention is an uncontrolled tooth flank change in one Prevent printing unit drive and an adjustable, the different needs create adaptable device for printing elimination of printing processes.
- the object of the invention is to provide a device for eliminating the game Overcomes disadvantages of the prior art.
- a gear train of a rotary machine is shown schematically.
- a printing machine as an example.
- drive gears 1, 2 and 3 for Printing unit cylinder of an offset printing unit shown.
- a plate cylinder Drive gear 1 a rubber cylinder, a drive gear 2 and a pressure cylinder assigned a drive gear 3.
- the drive gears 1 - 3 are driving Connection, with the drive from the impression cylinder towards the plate cylinder, i.e. from the drive gear 1 via the drive gear 2 to the drive gear 1.
- Fig. 2 the meshing between the drive gears 1 to 3 are enlarged and detailed or illustrated.
- the drive gear 2 of the blanket cylinder stands with the Drive gear 1 of the plate cylinder and the drive gear 3 of the printing cylinder in Drive connection. In the drive direction from the drive gear 3, this is on Drive gear 2 or a tooth 4 in point A. According to the drive direction is the drive gear 2 with a tooth 5 on the drive gear 1 at point B. To the exact transport of the image to be printed, it is necessary that these flank systems in points A and B are retained throughout the entire printing process. If necessary, but due to different diameters of blanket cylinders and Plate cylinder or due to different paper thicknesses due to the friction on the Cylinder surfaces result in a different game constellation.
- the drive gear 1 of the plate cylinder and the drive gear 3 are Printing cylinder shown.
- the impeller 6 is arranged between the two. This is evident from the type of flank system that faces away from the drive direction.
- the follower wheel 6 is arranged on a bearing block 8 fixed to the frame. Connected to the Bearing block 8 in turn, a bearing lever 9 is pivotally arranged.
- the bearing lever 9 can by means of a clamping device 10, which contains a spring assembly and with a Clamping screw can be preloaded against the bearing block 8.
- the idler gear 6 is rotatably mounted.
- the tensioning device 10 moves due to their set bias, the bearing lever 9 with the idler gear 6 a pivot point 11 on the frame fixed bracket 8 such that it is in the gap is pulled between drive wheels 1 and 3. Thereby come to the Gear meshes C and D each on the tooth flanks facing away from the drive Drive gears 1 and 3 with the teeth of the idler gear 6 in system.
- the mounting of the impeller 6 is described in more detail in FIG. 4.
- the drive gear 2 is arranged on a shaft journal 12 in a frame part 13. Coaxial to Drive gear 2, the idler gear 6 is arranged on bearing devices 14.
- the Bearing devices 14 are described in Fig. 5 below.
- the idler gear 6 is also connected to a bearing flange 15, the front of the shaft journal 12 grips without contact.
- the bearing flange 15 is bell-shaped and supports on its side facing the side gear 6, a bearing 16.
- the bearing 16 is again arranged on a collar 17 which is connected to the bearing lever 9.
- Of the Bearing lever 9 is on the bearing block 8 fixed to the frame by means of a stud bolt 18 arranged, which forms the pivot axis 11.
- the clamping device 10 With the Spring assembly.
- the spring assembly By adjusting the spring assembly using the clamping screw Clamping device 10 can be the idler gear by pivoting about the bearing axis 11 shift in its axial position relative to the drive gear 2.
- the idler gear 6 remains thereby freely rotatable on the bearing 16.
- Each storage device 14 has a Drive gear 2 attached retaining bolt 21 on the retaining bolt 21 passes through Idler gear 6 in openings 19.
- the openings 19 have a small dimension larger diameter than the retaining bolt 21 to a relative movement between To enable idler gear 6 and drive gear 2 and the retaining bolt 21.
- the Openings 19 can be provided in guide bushings.
- axial bearings 22 each on both end faces of the idler gear 6 arranged. So there is a thrust bearing 22 between the idler gear 6 and the drive gear 2 and between the screw 23 of the bearing pin 21 and the idler gear 6 is arranged.
- the axial bearings 22 each have flat bearing disks 24 and 25, or 26 and 27 on the inner bearing disks 25, 26 can against Displacement can be secured by the bushings in the openings 19.
- the outer Bearing washers 24, 27 are centered on shoulders of the retaining bolt 21. This allows the respective cage of the axial bearing 22 rotating and radially to the bearing washers 24 to 27 move without the storage can shift. That way it will Follower gear 6 in all movement states at an exactly constant distance from Drive gear 2 held.
- the device has the following functionality:
- the relative By holding the idler gear 6 by means of the bearing flange 15, the relative is pivotable to the drive gear 2, results when the drive gear 2 rotates a permanent relative movement in the radial direction between the drive gear 2 and Idler gear 6.
- This relative movement which is in the manner of a wobble represents, is made possible by the axial bearing 22 in the bearing devices 14, whereby the impeller 6 in the area of the openings 19 opposite the drive gear 2 can move.
- the axial bearings 22 on the one hand hold the idler gear 6 in exact parallel orientation to the drive gear 2 but leave on the other side Relative movement parallel and radial to the drive gear 2.
- the type of suspension of the idler gear 6 relative to the drive gear 2 is of course possible in a different way than shown in the above example.
- the idler gear 6 on the drive gear 2 can also be linear guided adjusting device be attached. Since the drive play is relatively small, is also a sufficiently precise adjustment of the Beiinstarzahnrades 6 possible, its displacement by the pivot radius of Bearing lever 9 out of the necessary engagement space out of a maximum dimension will exceed.
- the device is very compact in the manner shown to arrange and can also be easily assembled. The drive gear 2 only has to little changed, so that the effort for installing the device larger would require effort.
