Definitions

the improvement relates to a device for adjusting the use of friction in inking units of printing presses according to the preamble of claim 1.
a device of this type is known from DE 38 14 927 C1.
friction rollers are used to distribute the printing ink to be transported, which perform an axially reciprocating movement.
DE 38 14 927 C1 describes an intermediate gear in printing machines for adjusting the phase position of the axial rubbing movement of friction rollers. It serves to make the reciprocating movement of the friction rollers in an inking unit of a printing press adjustable in relation to a general rotational movement in a printing unit.
the intermediate gear mentioned is inserted between the drive from the printing press and the crank-shaped output toward the friction rollers. It has an eccentrically attached crank pin on a drive shaft, which carries a transmission element.
a gearwheel is provided on the transmission element and, on the other hand, a disc is attached, which carries three cam rollers. The cam rollers engage in corresponding openings in a control disk which is mounted on the drive shaft.
the openings Compared to the diameter of the cam rollers, the openings have a diameter enlarged by the degree of the eccentricity of the crank pin.
the gearwheel on the transmission element engages in an internal toothing of an output element which is mounted in the housing of the intermediate gear.
a drive lever for the reciprocating movement of the friction rollers is slidably coupled to this output element. The coupling takes place in a known manner.
the control disk is in turn provided with an external toothing in which an adjusting gear engages, which can be held or adjusted by a chain drive.
the drive movement takes place through eccentric rotation of the transmission element.
the gearwheel of the transmission element rolls in the internal toothing of the output element and drives it with the appropriate reduction.
the transmission element remains at rest, the cam rollers rotating in the openings of the control disk.
the intermediate gear is quite compact, but it is relatively complicated and expensive to manufacture.
the task of the improvement is therefore to make the transmission cheaper to manufacture and yet more compact.
FIG. 1 shows a section through the device in one plane through a central axis.
the device is attached to the machine frame 1 of a printing press. It initially contains a drive gear 2, which is connected to a machine-synchronous part of the drive of the printing press.
the drive gear 2 is mounted on a shaft 3.
the shaft 3 is supported on one side by means of a bearing 4 in the machine frame 1.
a drive toothing 5 and a needle bearing 6 are provided side by side in the axial direction.
the wedge connection 6 engages in an output element 7.
the output element 7 is in principle constructed as a hollow cylindrical body, which is formed on the inside corresponding to the needle bearing 6 on the end of the shaft 3.
a clamping device 8 is also provided on the output element 7.
a drive lever 9 is pivotable via a collar sleeve 10, e.g. attached via a roller bearing.
the drive lever 9 leads to deflection gears for the initiation of a reciprocating movement of friction rollers in an inking unit of the printing press.
the clamping device 8 allows the coupling of the drive lever 9 at different positions with respect to the axis of rotation of the output element 7. This results in crank movements with different radius or stroke with rotation of the output element 7.
the clamping device is of conventional design and is designed, for example, as a T-piece in a corresponding groove. The T-piece can be clamped at any point in the groove by means of a screw in the axis of movement of the drive lever 9.
the shaft 3 in the area of the drive toothing 5 is assigned at least three planet gears 12.
the planet gears 12 are each seated on a bearing pin 13 which is arranged on the output element 7 on the side opposite the clamping device 8.
the planet gears 12 finally mesh on the outside with the internal toothing 15 of a ring gear 14.
the ring gear 14 is ring-shaped and has an adjusting ring gear 16 on the outside.
the ring gear 14 has on one side a guide ring 22 which extends laterally of the gear ring 16.
the gear arrangement is centered via a bearing 11, by means of which the output element 7 is guided in an upper housing part 18.
the upper housing part 18 is connected to the machine frame 1 by means of a lower housing part 17.
the ring gear 14 is rotatable, but is guided entirely without a bearing.
the guide ring 22 of the ring gear 14 is rotatably seated in a centering collar 23 which extends as an annular backward rotation to the side of the bearing seat on the upper housing part 18.
the ring gear 14 lies with the side facing away from the guide ring 22 against a guide collar 25 on the lower housing part 17.
the whole arrangement is finally attached to the machine frame 1 by means of the lower housing part 17.
the lower housing part 17 can be centered on the bearing 4 to the center of the shaft 3.
An actuating shaft 20 is rotatably mounted in the upper housing part 18. It carries an adjusting gear 19 which meshes with the adjusting teeth 16 of the ring gear 14. On the other end of the adjusting shaft 20, a chain wheel 21 is arranged, to which a chain drive, not shown, is connected.
Upper housing part 18 and lower housing part 17 are aligned with one another via a collar 24, connected to one another with a plurality of retaining screws and fastened to the machine frame 1 via the lower housing part 17.
the device is shown as a section in the plane of the planet gears 12 through the illustration of Figure 1.
the concentric arrangement of shaft 3, planet gears 12 and ring gear 14 can be clearly seen.
actuating gear 19 in engagement with adjusting toothing 16 is shown on the top of ring gear 14, actuating gear 19 in engagement with adjusting toothing 16 is shown.
the sprocket 21 is concentric with this.
the attachment is cut at three points on the upper housing part 18.
the lower housing part 17 and the attachment points to the machine frame 1 are partially visible.
the function is as follows:
the device represents an epicyclic gear.
the output element 7 represents the web of the epicyclic gear.
the drive movement takes place via the drive gear 2 from the printing press.
the movement is subsequently from the drive toothing on the shaft 3 to the planet 12 and from this via the bearing pin 13, with a corresponding reduction of, for example, 1: 3 or 1: 4, on the web or the output element 7 transmitted.
the ring gear 14 is held in place by the setting gear 19.
the ring gear rotates in its seat between the upper housing part 18 and lower housing part 17.
the output element 7 rotates via the needle bearing 6 on the shaft 3.
the adjustment can be carried out remotely.
