Abstract
The invention relates to the technical field of accessories of printing machines, in particular to a transmission shaft for a large printing machine. The transmission shaft comprises an axis with external threads and a wearing layer which is matched with the axis and provided with internal threads, and the axis is connected with the wearing layer through locking devices; and connecting holes are formed in the two ends of the axis and the two ends of the wearing layer respectively, one ends of the locking devices are connected with the connecting holes in the axis through hexagon socket screws, and the other ends of the locking devices are connected with the connecting holes in the wearing layer through hexagon socket screws. The axis and the wearing layer are connected in a threaded fit manner, the wearing layer can be conveniently replaced, cost is saved, and the design is novel. In addition, the locking devices are arranged at the two ends of the axis and the two ends of the wearing layer, so that the axis and the wearing layer are more stable and safer.
Description
Technical field
The present invention relates to printer accessory technical field, be specifically related to a kind of transmission axle for large-sized print machine.
Background technology
The material of the transmission axle of large-sized print machine is now all corrosion-resistant steel, transmission axle surface directly contacts with paper or flexiplast product, after transmission axle works long hours, will wear and tear in transmission axle surface, cause transmission axle surface and paper or flexiplast product the friction force on surface inadequate, paper or flexiplast product are skidded in course of conveying, cause the local stacking of paper or flexiplast product, the cost of transmission axle is higher, if change whole transmission axle, can increase operation cost to enterprise.So existing technical scheme is provided with wearing layer to transmission axle outside face, but wearing layer is not easy to take off, and adds difficulty to replacing wearing layer, so the existing method transmission axle that directly replacing one is new often, adds the operation cost of enterprise.
Summary of the invention
The object of the present invention is to provide one, with low cost, wear-resisting antiskid, changes outer rear reusable transmission axle.
In order to achieve the above object, the technical solution used in the present invention is: a kind of transmission axle for large-sized print machine, comprise and have externally threaded axle center and the female wearing layer of tool with described axle center adaptation, described axle center is connected with wearing layer by blocking device; Described axle center and wearing layer two ends are respectively equipped with connecting bore, and one end of blocking device is connected with the connecting bore on axle center by socket bolt, and the other end is connected with the connecting bore on wearing layer by socket bolt.
As above for a transmission axle for large-sized print machine, illustrate further into, described blocking device is the connecting strap of two ends perforate.
As above for a transmission axle for large-sized print machine, illustrate further into, the two ends in described axle center are provided with chamfering.
The invention has the beneficial effects as follows: 1, adopt axle center to be connected by screw thread fit with wearing layer, can easily wearing layer be changed, save cost, novel in design.2, be provided with blocking device in axle center and wearing layer two ends, make the more firm safety of axle center and wearing layer.3, be provided with wearing layer, protection increases skin friction force while axle center.
Accompanying drawing explanation
Fig. 1 is lateral plan of the present invention.
Fig. 2 is axle centre structure schematic diagram.
In figure: 1, axle center; 2, wearing layer; 3, blocking device; 4, connecting bore.
Detailed description of the invention
Below in conjunction with accompanying drawing, elaboration detailed is further done to the present invention.
As shown in Fig. 1 to 2, a kind of transmission axle for large-sized print machine provided by the invention, comprise and there is externally threaded axle center 1 and the female wearing layer 2 of tool with described axle center 1 adaptation, wherein, move by described outside thread described wearing layer 2 relative to the engagement of described negative thread in described axle center 1, namely wearing layer 2 can be flexibly connected on axle center 1.Thus wearing layer 2 can easily be changed, save cost.
Described axle center 1 is stainless steel, can be set to hollow structure, alleviate the weight in axle center 1 successively.Wearing layer 2 can adopt stainless steel equally, also can adopt rubber.Adopt rubber, the friction coefficient of this transmission axle outside face can be increased, thus the friction force between this transmission axle outside face and paper or flexiplast product increases, paper is moved towards the direction needed, non-slip, paper or flexiplast product can be flattened, make product keep smooth always.
Described axle center 1 is connected with wearing layer 2 by blocking device 3; Described axle center 1 and wearing layer 2 two ends are respectively equipped with connecting bore 4, and described connecting bore 4 preferred version is tapped bore.Described blocking device 3 preferred version is the connecting strap of two ends perforate.One end of blocking device 3 is connected with the connecting bore 4 on axle center 1 by socket bolt, and the other end is connected with the connecting bore 4 on wearing layer 2 by socket bolt.Preferred version is, described axle center 1 and wearing layer 2 are provided with three groups of blocking devices 3 with one end, and these three groups of blocking devices 3, are uniformly distributed around axle center 1, and angle is between any two 120 °.By adopting blocking device 3, make the more firm safety of axle center 1 and wearing layer 2.
The two ends in described axle center 1 are provided with chamfering, facilitate the rotation of wearing layer 2 to import.But when needing to change wearing layer 2, blocking device 3 of first back-outing, at back-out wearing layer 2, changes a new wearing layer 2, again locking blocking device 3.Do not need to replace axle center 1, greatly saved cost.
The present invention is not limited to above-mentioned example, and in claims limited range of the present invention, the various distortion that those skilled in the art can make without creative work or amendment are all by the protection of this patent.
