Abstract
The utility model provides a kind of mechanical supporting device being applied to printer printing roller, due to adding of eccentric centre circle, instead of eccentric bushing and complete printing cylinder tripping, the requirement of combined pressure and pressure regulation, the sliding friction in eccentric bushing and wallboard hole is become rolling friction, improve the flexibility of clutch pressure, effectively can not only solve the printing ghost image because traditional eccentric bushing structure brings and black thick stick problem, and make this device can alleviate the impact of neutral impact phenomenon on whole printing cylinder support unit due to the physical characteristic of the new version of rolling element and the embedded flexible body excellence be made up of macromolecular material.
Description
Technical field
The utility model relates to a kind of supporting arrangement, especially a kind of mechanical supporting device being applied to printer printing roller.
Background technology
In traditional printing machine, printing cylinder has the particular/special requirement of tripping, combined pressure and pressure regulation, namely the shaft core position of cylinder should be adjustable, moveable, the support unit of printing cylinder often selects eccentric bushing structure for this reason, the effect changing centre of the drum's distance is reached by rotating eccentricity cover, must be there is suitable radial clearance to ensure eccentric bushing flexible rotating in the eccentric bushing of this structure and wallboard hole, but also can bring because printing cylinder axis drifts about the printing ghost image and black thick stick problem caused.The problems such as the simultaneously impact of printing product quality that brings of printing cylinder neutral impact phenomenon and the damage of idler parts also cannot effectively be solved always.
Summary of the invention
Technical problem to be solved in the utility model is: provide a kind of mechanical supporting device being applied to printer printing roller transmission, this device effectively can not only solve printing ghost image because traditional eccentric bushing structure brings and black thick stick problem, and can alleviate the impact of neutral impact phenomenon on whole printing cylinder support unit.
The technical scheme that the utility model adopts is: a kind of mechanical supporting device of printer printing roller, comprise bearing outer ring, flexible body, rolling element, bearing inner race, printing cylinder, location snap ring, eccentric centre circle, end cap, hold-down screw, bearing block, it is characterized in that, described printer printing roller axle journal place is provided with bearing inner race, printing cylinder and bearing inner race are fixed by fixing snap ring, eccentric centre circle is added in the middle of bearing inner race and bearing outer ring, eccentric centre circle and be evenly equipped with rolling element between bearing inner race and bearing outer ring, rolling element is embedded with flexible body, bearing outer ring is installed in bearing block, bearing outer ring, eccentric centre circle utilizes end cap and bearing block location, end cap is connected with bearing block by hold-down screw.
A mechanical supporting device for printer printing roller, is further characterized in that, bearing centre circle is eccentric design, and offset can design according to the size of roll printing pressure.
A kind of mechanical supporting device of printer printing roller, be further characterized in that, rolling element on the basis of solid cylinder rolling element, processes endoporus form hollow cylinder rolling element, at endoporus two ends design chamfering structure, embed flexible body at endoporus, the flexible body that endoporus embeds is by macromolecular material PTFE(polytetrafluoroethylene (PTFE) simultaneously) or PFA(perfluoroalkoxy resin) make.
The beneficial effects of the utility model are: due to adding of eccentric centre circle, instead of the requirement that eccentric bushing completes printer printing roller tripping, combined pressure and pressure regulation, the sliding friction in eccentric bushing and wallboard hole is become rolling friction, improve the flexibility of clutch pressure, also relatively reduce radial clearance.Meanwhile, the physical characteristic of the version that bearing roller is new and embedded flexible body macromolecular material excellence makes the bearing capacity of bearing itself good.In addition, rolling element has flexibility under the load of cylinders of printing press, can compensate the foozle of cylinder own and deflection deformation on the one hand, and the flexible body be made up of macromolecular material on the other hand effectively can also absorb the vibratory impulse energy of cylinder.
Accompanying drawing explanation
Fig. 1 is a kind of mechanical supporting device overall construction drawing of printer printing roller.
In Fig. 1,1 is bearing outer ring, and 2 is flexible body, and 3 is rolling element, and 4 is bearing inner race, and 5 is printing cylinder, and 6 is location snap ring, and 7 is eccentric centre circle, and 8 is end cap, and 9 is hold-down screw, and 10 is bearing block.
Detailed description of the invention
Below by specific embodiment, the utility model is described in further detail.
Embodiment one: as shown in Figure 1, a kind of mechanical supporting device of printer printing roller, comprise bearing outer ring 1, flexible body 2, rolling element 3, bearing inner race 4, printing cylinder 5, location snap ring 6, eccentric centre circle 7, end cap 8, hold-down screw 9, bearing block 10, it is characterized in that, the axle journal of printing cylinder 5 is connected with bearing inner race 4 by interference fit, and the groove that location snap ring 6 is placed in printing cylinder 5 is interior for preventing printing cylinder 5 from axial float occurring.Eccentric centre circle 7 is for realizing cylinder pressure regulation and clutch pressure, and its offset can design according to printing machine actual condition, and the sliding friction of traditional eccentric structure is become rolling friction by adding of eccentric centre circle, makes pressure regulation and clutch pressure flexibility and reliability more.Bearing outer ring 1 is placed in bearing block 10, is located on the right side of bearing outer ring 1 and eccentric centre circle 7 by bearing block 10, passes on left end cap 8 and locates, and bearing outer ring 1 and eccentric centre circle 7 top design have oilhole, is convenient to lubrication.End cap 8 is fixed on bearing block 10 by dog screw 9.Double rolling element 3 is furnished with respectively between eccentric centre circle 7 and bearing inner race 4, bearing outer ring 1, rolling element 3 endoporus embeds flexible body 2, the flexible body 2 that endoporus embeds is by macromolecular material PTFE(polytetrafluoroethylene (PTFE)) or PFA(perfluoroalkoxy resin) make, the hard and soft bi-unit composite structure of rolling element 3 makes the load-carrying properties of bearing own good, while the foozle compensating printing cylinder 5 and deflection deformation, effectively can also absorb the vibratory impulse energy that printing cylinder 5 produces in operation process.
