The device disclosed by the invention has the advantages of simple and compact structure, low cost and the like, is stable and reliable, is flexible in adjustment and is simple and convenient to process and assemble.
Description
Technical field
The present invention is mainly concerned with the printing equipment field, refers in particular to the axial direction positioning device of capacity eccentric bearing in a kind of printing cylinder.
Background technology
In printing assembly, often use three collar bearings as capacity eccentric bearing, it is mainly used in the supporting printing drum part and realizes that clutch presses work.Three collar bearings adopt the tricyclic structure form, and the rotation of in printing process, passing through adapter ring realizes the skew of printing cylinder axial line, thereby realizes that clutch presses work.Collar bearing is made up of outer shroud, adapter ring, interior ring respectively, by the rolling bearing transition, can rotate relatively flexibly between ring and the ring.Wherein, middle endless belt is eccentric, and the interior circle of adapter ring and the eccentric throw of cylindrical are a.Three collar bearings need be assembled in the hole of press rack; It uses comparatively complicated; Orientation angle from the relative frame of bearing hole; The outer shroud of designing requirement bearing circumferentially location is reliable with axial location, and wherein circumferentially locating is that interference fit through outer shroud and frame hole realizes that the axial location operated by rotary motion has axial direction positioning device.
Referring to Fig. 3, traditional axial direction positioning device comprises axial location part 5 and briquetting 6, and the gap m between briquetting 6 and axial location part 5 contact-making surfaces is difficult to guarantee simultaneously that three collar bearing axial locations and axial location part 5 rotate flexibly.The axial location of three collar bearings fixedly requires the gap little, and activity requires the gap relatively large flexibly.In addition, in installation process, the assurance in gap need be carried out match grinding to briquetting 6, and assembling process is loaded down with trivial details, complicacy.Moreover through long-time running with after clutch presses work repeatedly, the gap can increase gradually, and then is difficult to guarantee the axial location of three collar bearings.
Summary of the invention
The technical problem that the present invention will solve just is: to the technical problem that prior art exists, the present invention provide a kind of simple and compact for structure, with low cost, reliable and stable, adjustment flexibly, process and assemble the axial direction positioning device of printing cylinder capacity eccentric bearing in the easy printing unit.
For solving the problems of the technologies described above, the present invention adopts following technical scheme:
A kind of axial direction positioning device that prints printing cylinder capacity eccentric bearing in the unit; Comprise axial location part and briquetting; It is characterized in that: be equipped with one on the said briquetting and be used for the holding screw that cooperates with the axial location part; On an end of axial location part, offer containing hole on the said holding screw, be equiped with spin in the said containing hole.
As further improvement of the present invention:
Said holding screw is provided with adjusting nut.
Said containing hole is a round taper hole.
Be filled with lubricating grease in the said containing hole.
Compared with prior art; The invention has the advantages that: the present invention prints the axial direction positioning device of printing cylinder capacity eccentric bearing in the unit; Simple and compact for structure, with low cost, process and assemble easy; To the axial secure of capacity eccentric bearing, can take into account clutch pressure mechanism flexibly movable and three collar bearings and the fixing two aspect requirements of porthole axial location, and the free gap can be adjusted flexibly; When the axial location part when becoming big, can reach design gaps through adjustment at the wearing and tearing post gap.

The specific embodiment
Below will combine Figure of description and specific embodiment that the present invention is explained further details.
As shown in Figure 1, general three collar bearings 3 that adopt of the capacity eccentric bearing of printing cylinder in the printing unit, this three collar bearing 3 is made up of outer shroud 31, adapter ring 32, interior ring 33, by the rolling bearing transition, can rotate relatively flexibly between ring and the ring.Wherein, adapter ring 32 bands are eccentric, and circle is a with the eccentric throw of cylindrical in the adapter ring 32.Three collar bearings 3 are assembled in the hole of press rack 13, and the axial location of outer race 31 is reliably located through axial direction positioning device of the present invention.In printing process; Clutch presses driving force through connecting rod 1 ring flange 2 to be passed in torque, and the adapter ring 32 of ring flange 2 and three collar bearings 3 is affixed through first screw 4, thereby the adapter ring 32 of three collar bearings 3 is delivered in torque; Printing cylinder is supported on the interior ring 33 of three collar bearings 3; Through this cover mechanism, the printing cylinder center line can deflect, thereby realizes the clutch of printing cylinder.The outer shroud 31 of three collar bearings 3 adopts slight interference mode cold charge in wallboard hole; This kind fit can guarantee that three collar bearings 3 are radially static relatively with wallboard hole in printing machine clutch pressure process; But axially in clutch pressure process, has plus load; For it is located reliably in the axial direction, can adopt structure of the present invention.
As shown in Figure 2; The axial direction positioning device of printing cylinder capacity eccentric bearing in the printing unit of the present invention comprises axial location part 5 and briquetting 6, and 5 pairs three collar bearings of axial location part 3 carry out axial location; Briquetting 6 is used for limiting the position of axial location part 5, and briquetting 6 is connected on the frame 13 through screw 7.Be equipped with one on the briquetting 6 and be used for the holding screw 10 that cooperates with axial location part 5, on an end of axial location part 5, offer containing hole 11 on the holding screw 10, be equiped with spin 9 in the containing hole 11.In the present embodiment, containing hole 11 is a round taper hole, and is filled with lubricating grease in the containing hole 11, and holding screw 10 is provided with adjusting nut 8.A mill pin plane produces rolling friction on spin 9 and the axial location part 5, and adjusting nut 8 will be marked closely screw 10 lockings after configuring spin 9 suitable pressure.In clutch pressure process, spin 9 can be rolled on the plane of axial location part 5 flexibly; Simultaneously, can guarantee reliably again the axial location of three collar bearings 3 location not occur in order to guarantee mechanism through axial location part 5, left-hand axis will keep little gap b between keeper 5 and wallboard in Fig. 1.Can see that from above-mentioned clutch process and associated bearings structure axial location part 5 also can rotate with the adapter ring 32 of three collar bearings 3 synchronously in the clutch process.Therefore, the effect of axial direction positioning device of the present invention comprises two aspects: one, the axial restraint of three collar bearings 3 (capacity eccentric bearing).Two, take into account clutch pressure mechanism movable flexibly and three collar bearings 3 fix with the porthole axial location.
Below only be preferred implementation of the present invention, protection scope of the present invention also not only is confined to the foregoing description, and all technical schemes that belongs under the thinking of the present invention all belong to protection scope of the present invention.Should be pointed out that for those skilled in the art some improvement and retouching not breaking away under the principle of the invention prerequisite should be regarded as protection scope of the present invention.
