Description
Technical Field
The invention relates to a roller bearing arrangement (rollenlageung) in a printing press, comprising: a roller; a shaft carrying the roller; and a roller retainer having a bore.
Background
Such roller bearings are used, for example, for supporting cam rollers/curve rollers (Kurvenrollen).
DE 102005009300B 4 discloses a roller bearing in a gripper control gear, which comprises a gripper shaft, which is provided in a rotationally fixed manner with a roller lever having a curved roller, which rolls on a gripper control curve arranged concentrically to the printing cylinder.
Disclosure of Invention
The object of the invention is to provide a further roller bearing arrangement in a printing press.
This object is achieved by a roller bearing arrangement in a printing press, comprising a roller, a shaft carrying the roller, and a roller holder having a bore, characterized in that the shaft is a hollow shaft, a tensioning screw is inserted through the hollow shaft, the tensioning screw is screwed into a cover part, and a clamping ring is arranged in the bore, which clamping ring is compressed in the axial direction by the force of the tensioning screw and thereby expands in the radial direction, whereby the hollow shaft and the roller holder are clamped to one another in the radial direction.
The invention has the advantages that: the roller bearing is easier to install in its manufacture and maintenance.
Different modifications are possible:
the clamping ring can be either constructed consecutively or in segments (segmentiert) in the circumferential direction.
The clamping ring may be molded onto the hollow shaft or rest on the hollow shaft.
The clamping ring may have a serpentine-like profile or be corrugated.
The clamping ring may be a disc spring or a stack of disc springs.
The cover may have a step.
The step can be dimensioned in such a way that, when the tensioning screw is tightened, the step is first pressed onto the outer surface of the roller holder and then the inner surface of the cover is pressed onto the clamping ring.
The roller can be a rolling bearing with at least one inner ring, wherein, when the tensioning screw is tightened, firstly the inner ring is tensioned in the axial direction with the roller holder and then the clamping ring is clamped in the radial direction with the roller holder.
The roller holder can have a fork comprising a first fork arm and a second fork arm, the roller being arranged between the first fork arm and the second fork arm, and the hollow shaft can be clamped in the radial direction by a clamping ring with the first fork arm and by a further clamping ring with the second fork arm, wherein the further clamping ring is compressed in the axial direction by the force of the same tensioning bolt just as the clamping ring mentioned above and thereby expands in the radial direction.
A plurality of rings can be provided on the hollow shaft and can be tensioned axially relative to one another when the tensioning screw is tightened, which can be achieved before the two clamping rings are clamped radially to the two fork arms.
The two clamping rings can be geometrically and rigidly matched to one another, so that the clamping ring mentioned above first clamps with the first prong and subsequently the further clamping ring with the second prong in the radial direction.
A hole may be provided in the first prong and a further hole in which the further clamping ring is arranged may be provided in the second prong.
The two holes may be sized differently from each other in diameter.
The roller holder can be arranged on a lever of a gripper system for gripping a printed sheet.
Drawings
Further developments can also be taken from the following description of the embodiments and the figures.
The sole figure 1 shows a roller holder for a gripper system in a printing press with curved rollers supported therein.
Detailed Description
The roller bearing arrangement comprises a roller 1 in the form of a rolling bearing and comprises a roller holder 2 in the form of a fork 12, which fork 12 has a first fork arm 13 and a second fork arm 14, the roller 1 being arranged between said first fork arm 13 and said second fork arm 14. The rollers 1 are curved rollers of a gripper system 21, which gripper system 21 is arranged in the printing press for holding the printed sheet on the cylinder. First prong 13 has aperture 3 and second prong 14 has a larger diameter aperture 16 aligned therewith.
In these bores 3,16, a hollow shaft 4 is provided, and clamping rings 7,15 are formed on the hollow shaft 4. A tensioning screw 5 passes through the hollow shaft 4, said tensioning screw 5 being screwed into the cover element 6 and being pressed with its screw head axially onto the other cover element 22. These cover elements 6,22 can also be referred to as pressure blocks on the basis of their function. On the hollow shaft 4, rings 17,18 are provided, and an inner ring 11 of a rolling bearing is arranged between them, which rolling bearing also comprises an outer ring 19. The rolling elements 20 run between the inner ring 11 and the outer ring 19.
The cover 6 has a step 8, the diameter of said step 8 being larger than the diameter of the hole 3, so that the step 8 is supported on the first yoke 13 in the axial direction. The other cover 22 has a step 23, the diameter of which step 23 is smaller than the diameter of hole 16, so that step 23 is not supported on second prong 14 in the axial direction.
These clamping rings 7,15 have the following properties: the radial extensions react to the axial pressure load. This property is produced by the meandering-like contour of the respective clamping rings 7,15, wherein these clamping rings 7,15 can be made of metal (for example steel).
The functional mode of this structure is as follows:
in the first step, these rings 17,18 and the inner ring 11 are pressed against each other in the axial direction when the tensioning screw 5 is tightened. The step 23 presses on the clamping ring 7, and the clamping ring 7 presses on the ring 18, and the ring 17 bears on the inner surface of the first yoke 13. The radially outer region of the inner surface 10 of the step 8 already rests on the outer surface 9 of the first prong 13 at this stage.
In the case of further tightening in the second step, the step 8 is elastically bent, thereby increasing the pressure exerted by the radially outer region of the inner surface 10 on the clamping ring 7 (15). Due to this axial loading of the flat side of the clamping ring 7, the clamping ring 7 expands in the radial direction, whereby the clamping ring 7 is clamped by its outer circumferential surface with the first yoke 13 and by its inner circumferential surface with the cover 6, respectively. In this way, the cover 6 and the first yoke 13 are fixedly connected to each other.
If tensioning bolt 5 is tightened still further in the third step, this causes final cap 22 to be fixedly connected to second prong 14 by clamping action. The clamping ring 15, on the basis of its own dimensions, has not yet been expanded in the radial direction to this extent in the second step, whereas the clamping ring 15 is expanded in the third step so strongly that the clamping ring 15 is clamped by its outer circumferential surface with the second prong 14 and by its inner circumferential surface with the cover 22, respectively. In this manner, cover 22 and second prong 14 are fixedly connected to one another. This expansion in the radial direction is triggered by the step 23 pressing axially against the flat side of the clamping ring 15.
With regard to the mounting reliability, it is advantageous that in the roller bearing arrangement, it is necessary to first exclude the axial gap between the roller 1 and the roller holder 2, then the radial gap between the cover 6 and the roller holder 2, and finally the radial gap between the other cover 22 and the roller holder 2. Thereby eliminating erroneous installation sequences that could lead to chatter and wear.
