Definitions
- the invention relates to a storage for cylinders and drums in Printing machines, preferably for the operator side.
- Storage can concern and is a roller bearing or a plain bearing according to their design preferably designed as a floating bearing.
- a storage of this type is for example from DE 3 324 811 A1 known as roller bearings for the journals of rubber cylinders.
- From DE-PS 755 282 is a further storage in a rubber cylinder known.
- the rubber cylinder is from a thru axle worn and is included in bearings in the machine frame Flanged sleeves through which the thru axle is also guided is.
- DE 4 227 643 A1 describes a bearing for cylinders and drums in Printing machines known.
- the pin of a cylinder or a drum is in the collar a drive wheel detachably added.
- the collar is part of the drive wheel and is rotatably arranged in a bearing in the side frame.
- a cylinder of a printing press which is equipped with a Axle journal is welded.
- the pin axially takes a tapered collar in a frame supported mandrel, fitting collar and pin by means of connecting element are detachably screwed in the axial direction.
- GB-A 1 247 649 describes a bearing for a printing press cylinder known.
- the pin of the cylinder is received in a sleeve with a conical outer jacket.
- the sleeve forms a tapered bore for centering the inner ring Journal.
- the object of the invention is to develop a solution that the mentioned disadvantages noticeably minimized.
- the storage according to the invention is preferred for printing presses as Suitable for floating bearings. With appropriate support in the longitudinal direction (Axial) the bearing is also suitable as a fixed bearing. Warehousing can be designed as roller bearings or plain bearings. Through the Centering of the cylinder to the inner ring of the bearing and the plane-parallel, Detachable connection of cylinder and inner ring becomes one Inexpensive cylinder bearing achieved that is easy to insert or remove the cylinder between the side frames and, for example, the curves on the inside allowed. The assembly times are shortened and the service expenditure is reduced.
- the storage represents an inexpensive version By forming the inner ring with flat surfaces that can Bearings are made slightly larger in its outer dimensions, so that the bearing hole in the frame is also slightly larger. This has the advantage that cylinders with longer ones are in the frame reaching stub ends without swiveling the frame walls can be assembled or disassembled.
- the inner ring provides the bearing shell or bush.
- a Rolling bearing In the hole of a frame 2 on the operator side (B side) is a Rolling bearing according to Fig. 1 arranged.
- the rolling bearing consists of one eccentrically designed outer ring 3, a central inner ring 5 and rolling elements 4 arranged therebetween and carries a cylinder 1.
- the inner ring 5 protrudes into the space between the two side frames towards a cylinder face 11 and takes the Pin stub 12 with circumferential centering 8 on the associated Centering 8 'on.
- the inner ring 5 also has a the cylinder 1 adjacent end face, which as a flat surface 7th is executed.
- the flat surface 7 is assigned to a cylinder shoulder 13 a flat surface 7 'is arranged.
- the neighboring flat areas 7 'and 7 form over several connecting elements 6, e.g. Screws, a detachable positive connection from cylinder 1 and inner ring 5 of storage.
- a cover 10 can be used as a protective device.
- the cylinder 1 no journal stub 12.
- a centering 9 is arranged, one on the circumference of the inner ring 5 located centering 9 'is assigned.
- the inner ring 5 has, as already described, a flat surface 7 on the Cylinder shoulder 13 is assigned a flat surface 7 '.
- About fasteners 6 is the releasable positive connection of Cylinder 1 and inner ring 5 formed as already described.
- the cylinder 3 shows a further embodiment of the storage according to the invention, which especially for cylinders or drums with low Weight or suitable for rollers.
- the cylinder e.g. a sheet-guiding drum, has a cylinder shoulder 13, in the center of the axis incorporated a conical centering 14 ' is.
- the centering 14 ' is assigned a centering tip 14 which is arranged on the flat surface 7 of the inner ring 5.
- the inner ring 5 consists, in this embodiment on the flat surface 7, of a Solid material.
- the inner ring 5 can continue as a solid shaft Centering tip 14 may be formed.
