Definitions
- the improvement relates to a device for adjusting the trituration insert in inking units of printing machines according to the preamble of the claim 1.
- a device of this type is known from US-A-2700335 known.
- the openings have a around the diameter of the cam rollers Measure of the eccentricity of the crank pin enlarged diameter.
- the Gear on the transmission element engages in an internal toothing
- 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 object of the improvement is therefore to make the transmission cheaper to manufacture and to make it even more compact.
- FIG 1 is a section through the device in a plane through a central axis shown.
- the device is on the machine frame 1 of a printing press appropriate. It initially contains a drive gear 2 with a machine-synchronized part of the drive of the printing press connected is.
- the drive gear 2 is mounted on a shaft 3.
- the shaft 3 is stored on one side by means of a bearing 4 in the machine frame 1.
- On the opposite side of the shaft 3 are side by side in the axial direction a drive toothing 5 and a needle bearing 6 are provided.
- the needle bearing 6 engages in an output element 7.
- the output element In principle, 7 is constructed as a hollow cylindrical body, on the inside formed according to the needle bearing 6 on the end of the shaft 3 is. On the output element 7 there is also a clamping device 8 intended.
- a collar sleeve 10 Drive lever 9 swiveling 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 permits the coupling of the drive lever 9 different positions with respect to the axis of rotation of the output element 7. This results in 7 crank movements when the output element rotates with different radius or stroke.
- the Clamping device is designed conventionally and for example as a T-piece in a corresponding groove.
- the T-piece can be anywhere the groove by means of a screw in the axis of movement of the drive lever 9 be clamped.
- the shaft 3 is at least in the area of the drive toothing 5 assigned three planet gears 12.
- the planet gears 12 each sit on one Bearing pin 13, which on the opposite of the clamping device 8 Are arranged on the output element 7 side.
- the planet gears 12 Finally, comb the outside with the internal toothing 15 of a ring gear 14.
- the ring gear 14 is annular and has one on the outside Set gear ring 16. Furthermore, the ring gear 14 has one on one side Guide ring 22 which extends laterally of the gear ring 16.
- the gear arrangement is centered by means of a bearing 11 the output element 7 is guided in an upper housing part 18.
- the Upper housing part 18 is by means of a lower housing part 17 with the machine frame 1 connected.
- the ring gear 14 is rotatable, but entirely without bearings
- the guide ring 22 of the ring gear 14 is rotatably seated in a centering collar 23, which is an annular backward rotation to the side of Bearing seat extends on the upper housing part 18.
- the whole arrangement is finally made using of the lower housing part 17 attached to the machine frame 1.
- the lower part of the housing 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. she wears a Setting gear 19, which meshes with the toothing 16 of the ring gear 14. On the other end of the control shaft 20, a sprocket 21 is arranged with which is connected to a chain drive, not shown.
- Upper housing part 18 and lower housing part 17 are mutually connected via a collar 24 aligned, connected with several retaining screws and attached to the machine frame 1 via the lower housing part 17.
- the device is a section in the plane of the planet gears 12th shown by the representation of Figure 1.
- the concentric one is clearly visible Arrangement of shaft 3, planet gears 12 and ring gear 14.
- the adjusting gear 19 in engagement with the Set teeth 16 shown.
- the sprocket 21 is concentric with it Attachment is cut at three points of 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 a planetary 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 forth. The movement is described below by the drive toothing on the Shaft 3 on the planet 12 and from this via the bearing pin 13, with a corresponding Reduction of 1: 3 or 1: 4, for example, on the bridge or the output element 7 transmitted.
- the ring gear 14 is in each case held on the adjusting gear 19. By turning the ring gear 14 with the adjusting gear 19, starting from the sprocket 21 and the adjusting shaft 20, is a change in the relative position of the output element 7 and the drive gear 2 possible.
- the ring gear rotates in its seat between the upper part of the housing 18 and lower housing part 17.
- the output element 7 rotates via the needle bearing 6 on the shaft 3. The adjustment can be remotely controlled respectively.

Description
Die Antriebsbewegung erfolgt durch exzentrischen Umlauf des Übertragungselements. Dabei rollt das Zahnrad des Übertragungselements in der Innenverzahnung des Abtriebselements ab und treibt dieses mit der entsprechenden Untersetzung an. Dabei bleibt das Übertragungselement abgesehen von der exzentrischen Bewegung relativ zum Gehäuse in Ruhe, wobei die Kurvenrollen in den Öffnungen der Steuerscheibe umlaufen. Durch Verstellen der Steuerscheibe mit dem Stellzahnrad kann die Abtriebsbewegung relativ zum Antrieb verstellt werden.
