Abstract
The utility model relates to a driving device for a plate cylinder of a roll paper offset press. The driving device comprises a driving gear and an outer spline sleeve mounted on the plate cylinder, wherein an inner spline for matching with the outer spline sleeve is arranged in an inner hole of the driving gear. The driving device for the plate cylinder of the roll paper offset press has the advantages of simple and compact structure, convenience in operation, high stability, high reliability and the like.
Description
Technical field
The utility model is mainly concerned with printing mechanism field, refers in particular to a kind of plate cylinder transmission device that is applicable to roll-fed offset printing press.
Background technology
Two aspect problems are mainly considered in the design of offset machine printing drum drive mechanism: one, and steadily uniform transferring power, guarantees the coating of printed matter surface ink evenly.For reaching this object, printing machine transmission generally adopts Helical gear Transmission.Two, because printing machine has forme chromatography requirement at actual mechanical process, chromatography is divided into again two kinds of circumferential and axial, in mechanism, the final result of circumferential and axial chromatography is: under the driving of associated mechanisms or electric-control system, allow plate cylinder circumferentially rotate or to move axially.
When plate cylinder is moving axially in process, if there is no associated mechanisms processing, must cause the variation of the axial position of travelling gear.Owing to adopting Helical gear Transmission, so, in this case, moving axially the variation that must cause plate cylinder circumferential position, original two independent chromatography adjustment operations have become interlock, and have certain proportion relation, and this is not allow in design.
Utility model content
The technical problems to be solved in the utility model is just: the technical problem existing for prior art, the utility model provides a kind of simple and compact for structure, easy and simple to handle, stationarity is good, reliability is high roll-fed offset printing press plate cylinder transmission device.
For solving the problems of the technologies described above, the utility model by the following technical solutions:
A kind of roll-fed offset printing press plate cylinder transmission device, comprises travelling gear and is installed on the external splines cover on plate cylinder, the endoporus of described travelling gear is for overlapping with external splines the internal spline coordinating.
As further improvement of the utility model:
Described external splines cover is fixed on the end of plate cylinder by more than one group connector.
Described connector is the combining structure of screw and alignment pin.
The end of described plate cylinder is provided with rigidity supporting structure.
Compared with prior art, the utility model has the advantage of: the utility model is simple and compact for structure, easy and simple to handle, can steadily print power with transmission at a high speed, guarantee printing quality when high speed printing, balanced controls vibrate the impact on printing quality.Meanwhile, the utility model has met the independence of axial and circumferential chromatographys, when plate cylinder runs up, utilizes involute spline self-centering, and dynamic balance performance is good.The utlity model has good installation capability, convenient for assembly.

The specific embodiment
Below with reference to Figure of description and specific embodiment, the utility model is described in further details.
In concrete application example, as shown in Figure 1, in the frame 1 that roll-fed offset printing press prints, plate cylinder 4 and blanket cylinder 5 are installed.As shown in Figure 2, the both sides of frame 1 are respectively frame driving face wallboard 2 and gantry operation facing-wall board 3, all cylinders are installed between frame driving face wallboard 2 and gantry operation facing-wall board 3, and plate cylinder transmission device of the present utility model is installed on frame driving face wallboard 2; Under specific works state, plate cylinder 4 has axially-movable (A to) and circumferential movement (B to).
Shown in Fig. 3 and Fig. 4, roll-fed offset printing press plate cylinder transmission device of the present utility model comprises travelling gear 6 and is installed on external splines on plate cylinder 4 cover 7, and by more than one group connector, fix, connector can adopt the combination of screw and alignment pin; The endoporus of travelling gear 6 is for overlapping 7 internal splines that coordinate with external splines.Adding man-hour, is endoporus and the fit clearance that external splines overlaps 7 splines that guarantees travelling gear 6, and two employings are joined and processed, and the spline tooth of travelling gear 6 and external splines cover 7 and spline one by one corresponding also work have processing mark.
As preferred embodiment, further in the end of plate cylinder 4, be provided with rigidity supporting structure 8, be convenient to install, improve operational reliability.
Like this, when roll-fed offset printing press turns round, driving torque reaches external splines cover 7 by travelling gear 6, and because external splines cover 7 is fixed as one with plate cylinder 4, so power can finally reach plate cylinder 4, printing equipment completes printing; That is: utilize involute spline to complete the power transmission of plate cylinder 4.When in roll-fed offset printing press axially La Ban mechanism (be installed on the gantry operation facing-wall board 3 in Fig. 2, not shown in the figures) drive plate cylinder 4 while moving axially (A direction), due to the transport characteristics of spline mechanism, the axially-movable of its plate cylinder 4 will can not have influence on the power transmission of roll-fed offset printing press at all.
Below be only preferred embodiment of the present utility model, protection domain of the present utility model is also not only confined to above-described embodiment, and all technical schemes belonging under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, in the some improvements and modifications that do not depart under the utility model principle prerequisite, should be considered as protection domain of the present utility model.
