Accompanying drawing explanation
From following to drawing embodiment and the description of the drawings in other structure and functionally favourable further scheme.In accompanying drawing:
Fig. 1 is the Local map of printing machine.
Detailed description of the invention
The Local map of printing machine shown in unique accompanying drawing.Described printing machine is the sheet-fed press for offset printing.Described Local map illustrates the lithographic offset printing units of printing machine, and it comprises blanket cylinder 2 and plate cylinder 3.In addition, described lithographic offset printing units also comprises anilox roll ink device 4, and described anilox roll ink device has ink and applies roller 5 and anilox roll (Aniloxwalze) 6.
In printing work, blanket cylinder 2 and ink apply roller 5 and to rest on plate cylinder 3 and described ink applies roller 4 rests in anilox roll 6.For the purpose of clearer, these cylinders 2,3 and roller 5,6 and supporting arrangement thereof are only shown schematically.
The overall diameter that ink applies roller 5 is under any circumstance substantially equally large with the overall diameter of plate cylinder 3, and the overall diameter of anilox roll 6 is preferably substantially equally large with the overall diameter of plate cylinder 3, but also can be less than the overall diameter of plate cylinder 3, be such as the half of plate cylinder overall diameter.
Blanket cylinder 2 is equipped with and rolls pillow 7, described in roll pillow and roll rolling on pillow 8 of plate cylinder 3, the pillow 9 that rolls that pillow and ink applies roller 5 that rolls of described plate cylinder forms Structure deformation.Can only see in the accompanying drawings corresponding roll pillow right be in the driving side of printing machine respectively roll pillow 7,8,9.
In order to drive described cylinder 2,3 and ink to apply roller 5 rotatably, there is drive transmission 10, this drive transmission the driving-energy of the master driver from printing machine is passed to cylinder 2,3 and ink applies roller 5.Anilox roll 6 equally can by described drive transmission 10 from described master driver obtain its rotary actuation energy or instead from independent of described master driver drive motors obtain driving-energy.Illustrate that torque DM is to the infeed (input) in component shown in drive transmission 10 with arrow.
First gear 11 and the second gear 12 belong to described drive transmission 10, and described first and second gears and described plate cylinder 3 are arranged coaxially.Second gear 12 not only axial restraint ground and also be connected with described plate cylinder 3 without relative rotation.First gear 11 engages with the 3rd gear 13, and described 3rd gear and described blanket cylinder 2 are arranged coaxially.Described 3rd gear 13 is with described blanket cylinder 2 axial restraint ground and be also connected without relative rotation.Described second gear 12 engages with the 4th gear 14, and described 4th gear and described ink apply roller 5 and arranges coaxially.Described 4th gear 14 and described ink apply roller 5 axial restraint ground and are connected without relative rotation.These gears 11,12,13 and 14 are angular gears.
There is the alignment adjusting device of the circumference alignment for regulating plate cylinder 3.Clutch 15 belongs to described circumference alignment adjusting device, and described clutch is axial compensation clutch or can the clutch of lengthwise movement.Described clutch 15 comprises first clutch half portion 16 and second clutch half portion 17.First clutch half portion 16 axial restraint ground and be such as connected by an axle with the first gear 11 without relative rotation.Second clutch half portion 17 axial restraint ground and to be connected by an axle such as equally with plate cylinder 3 without relative rotation.
When regulating the circumference alignment of plate cylinder 3, the first gear 11 in axial direction moves, and this schematically shows with double-head arrow.Alignment depending on expectation regulates direction, and the first gear is regulated by towards plate cylinder 3 or away from plate cylinder 3.At this, described can the first clutch half portion 16 of lengthwise movement together with described first gear 11 relative to second clutch half portion 17 along the longitudinal direction (axial direction) regulate.Because described clutch 15 allows to compensate between the first gear 11 and the axial location of plate cylinder 3, therefore this clutch is axial compensation clutch.Accordingly, clutch 15 is not conversion clutch.
When the first gear 11 carries out moving axially shown in double-head arrow together with first clutch half portion 16, first clutch half portion 16 and second clutch half portion 17 keep between them without to be connected in relative rotation and the first gear 11 keeps engaging with the 3rd gear 13.First gear 11 and the 3rd gear 13 are fitted to each other by helical teeth structure, and due to the wedging action of described helical teeth structure, described plate cylinder 3 is rotated based on being regulated by the circumference alignment desirably of the movement shown in double-head arrow of described first gear 11.
By means of not shown another gear engaged with described 3rd gear 13, in described 3rd gear, store torque DM.Stored torque is divided into the moment of components that blanket cylinder 2 is rotated and the moment of components being passed to the first gear 11 by the 3rd gear 13.The moment of components passing to the first gear 11 passes to the second gear 12 by the first gear 11 by clutch 15.Pass to the second gear 12 torque and be divided into the moment of components that plate cylinder 3 is rotated and the moment of components being passed to the 4th gear 14 by the second gear 12.The moment of components passing to the 4th gear 14 is delivered to this ink by make described 4th gear 14 and ink apply axle that roller 5 is connected and applies roller 5 and rotate to make it.
Because roll pillow 9 to apply roller 5 with ink and be connected without relative rotation, roll pillow 8 to be connected without relative rotation with plate cylinder 3, roll pillow 7 to be connected without relative rotation with blanket cylinder 2, roll therefore pillow 8 and 9 jointly formed top friction drive and described in roll the friction pulley transfer device that pillow 8 and 7 forms bottom jointly.
By the 4th gear 14 pass to ink apply roller 5 and thus pass to its part of rolling the torque of pillow 9 by described roll that pillow 9 passes to plate cylinder based on friction pulley effect roll pillow 8.Produce counteractive torque thus, i.e. so-called idle moment (Blindmoment), its loop utilizes four arrows (having hacures) to schematically show.A part for the torque passing to plate cylinder 3 by the first gear 11 by clutch 15 and roll pillow 8 passes to based on rolling pillow 8 and the friction pulley effect of rolling pillow 7 roll pillow 7 by rolling pillow 8.The loop of the so-called idle moment of the friction drive of bottom utilizes four arrows (shadow-free line) to represent in the accompanying drawings equally.
Cause conclusive advantage by two gears 11,12 coaxially to each other and the existence of clutch 15 of arranging between which, this conclusive advantage is as follows: only transmitted the idle moment of the friction drive of described bottom by clutch 15 and do not transmit the idle moment of the friction drive on described top.Thus can idle moment stream directly in unambiguously determination clutch 15 and in fact get rid of the load variations reaction caused by described idle moment in clutch 15.Because described two idle moment streams do not meet in clutch 15, therefore these idle moment streams can not influence each other in clutch 15, thus the ballistic kick carried out along direction of rotation making in fact to get rid of clutch 15 is wrenched and the wearing and tearing caused thus of clutch 15.
This wearing and tearing avoided in arrangement of the present invention and otherwise can be caused by the load variations reaction of the temporary transient uncharge state of clutch and clutch, this wearing and tearing are also referred to as " fretting corrosion ".This fretting corrosion is farthest avoided in arrangement of the present invention, thus makes clutch 15 have the extremely long life-span.
