The utility model discloses a driving component for a printing cylinder on a printing machine. The driving component comprises a driving motor and a speed reducer which are connected with each other, wherein, a transmission flange is arranged on an output shaft of the speed reducer; more than one transmission pin is arranged on the transmission flange; and the transmission pin is connected with a cylinder driving flange positioned at the end part of the printing cylinder. The driving component has the advantages of simple and compact structure, low cost, small spatial distribution, better work reliability, and the like, and is more convenient to assemble and debug.
Description
Technical field
The utility model is mainly concerned with the printing equipment field, refers in particular to a kind of driven unit of printing cylinder.
Background technology
The direct drive mode of existing shaftless printing press is to adopt each printing cylinder that the separate electrical motor method of driving is all arranged.Though this method has been simplified driving-chain, processing and installation difficulty have been reduced, but realize that servomotor directly drives the printing cylinder running, the connector (ball spline) and the support member (many collar bearings) of a lot of costlinesses have been increased, not only cost increases, and to guarantee the installation accuracy of these support members and associated components, as axiality, each roller spare circumferentially beats etc. after the installation.As shown in Figure 3, this Structural Design Requirement printing machine driving face wallboard must have two supporting constructions, makes that like this driving face frame dimensions is big and structure is comparatively complicated.Moreover, printing machine is because typography needs cylinder in good time moving axially in operation process, and the generation contradiction that is rigidly connected of this mobile meeting and driving-chain, so in Fig. 3 design, adopt ball spline as connecting transition piece, ball spline permission power output at two ends in operation process has relative moving axially with load elements, utilize these characteristics can well handle the axial needs of press printing technology intermediate roll, but structure is comparatively complicated.In addition, transfer motion power through reductor 2, finally reaches printing cylinder 11 by drive sleeve 22, ball spline shaft 17, pin 23 from drive motors 1 again, and transmission link is more, and structure is comparatively loaded down with trivial details.
The utility model content
The technical problems to be solved in the utility model just is: at the technical problem that prior art exists, the utility model provide a kind of simple and compact for structure, with low cost, space layout is little, assembling and setting is convenient, printing cylinder driven unit on the better printing machine of functional reliability.
For solving the problems of the technologies described above, the utility model by the following technical solutions:
Printing cylinder driven unit on a kind of printing machine, comprise continuous drive motors and reductor, it is characterized in that: the output shaft of described reductor is provided with drive flange, described drive flange is provided with more than one trundle, and described trundle links to each other with the drum driven flange that is positioned at the printing cylinder end.
As further improvement of the utility model:
Offer the pin-and-hole that cooperates with trundle on the described drum driven flange.
Be provided with sliding bearing in the described pin-and-hole.
The output shaft of described reductor links to each other with drive flange by key.
Described printing cylinder is fixed on the frame wallboard by three collar bearings, the middle endless belt off-centre of described three collar bearings, and promptly the eccentric throw of circle and cylindrical is a in the adapter ring.
The end of described printing cylinder is connected with axle sleeve, and the shell of described reductor links to each other with axle sleeve.
Compared with prior art, advantage of the present utility model is: printing cylinder driven unit on the printing machine of the present utility model, simple and compact for structure, with low cost, space layout is little, be easy to the assembling; Owing to saved at least one sets of transmission mechanism, so cost reduces greatly, and assembling and setting is convenient, and functional reliability is better.The utility model is applied widely, satisfies printing machine because the in good time axially movable designing requirement in operation process of typography needs cylinder.

The specific embodiment
Below with reference to Figure of description and specific embodiment the utility model is described in further details.
As depicted in figs. 1 and 2, printing cylinder driven unit on the printing machine of the present utility model comprises continuous drive motors 1 and reductor 2, and drive motors 1 adopts servomotor, the output shaft of reductor 2 is provided with drive flange 5, and the output shaft of reductor 2 links to each other with drive flange 5 by key 16.Be installed with more than one trundle 7 with screw 6 and pad on the drive flange 5, trundle 7 links to each other with the drum driven flange 8 that is positioned at printing cylinder 11 ends, and drum driven flange 8 is connected on the end of printing cylinder 11 with alignment pin 15 by second screw 14.In the present embodiment, offer the pin-and-hole 18 that cooperates with trundle 7 on the drum driven flange 8, be provided with sliding bearing 9 in the pin-and-hole 18.Printing cylinder 11 is fixed on the frame wallboard 13 by three collar bearings 10, and the end of printing cylinder 11 is connected with axle sleeve 3 by the 3rd screw 12, and axle sleeve 3 is provided with forming machanism 4, and the shell of reductor 2 links to each other with axle sleeve 3.
The utility model can satisfy following 2 points: one, can satisfy printing cylinder 11 and move axially requirement in the printing machine operation process.Two, can satisfy clutch and press when doing, drive motors 1 is with printing cylinder 11 servo-actuateds and keep the transmission axis consistent.Particularly, when printing cylinder 11 need move axially because of typography, because drum driven flange 8 is to cooperate transition to be connected by sliding bearing 9 with trundle 7, so, when drum driven flange 8 moves axially, can not produce extra axial force, and and then influence the normal transmission of drive motors 1 drive motors 1.
In this enforcement, the middle endless belt off-centre of three collar bearings 10, promptly the eccentric throw of circle and cylindrical is a in the adapter ring.In printing process, the clutch pressure mechanism driving force is passed to the clutch driving torque by axle sleeve 3 centre circle of three collar bearings 10, printing cylinder 11 is supported on the inner ring of three collar bearings 10, and at this moment printing cylinder 11 center lines can deflect, thereby realizes printing cylinder 11 clutches.Printing cylinder 11 is in clutch pressure process, and drive motors 1 all is fixed on the axle sleeve 3 with reductor 2, so drive motors 1 can keep the unanimity of transmission axis with printing cylinder 11 actions in printing cylinder 11 clutch pressure processes.
Below only be preferred implementation of the present utility model, protection domain of the present utility model also not only is confined to the foregoing description, and all technical schemes that belongs under the utility model thinking all belong to protection domain of the present utility model.Should be pointed out that for those skilled in the art the some improvements and modifications not breaking away under the utility model principle prerequisite should be considered as protection domain of the present utility model.
