Profile.If roller is in lower position, it be stressed that the conspicuousness of the bending of axle, wherein, the axle is not only due to bear
Lotus and bend and bent due to deadweight.
In figures 3 and 4 the axle 11 according to the present invention is shown from side.Each end section 19 and 20 is configured with change
Region 31, in the region of variation, the axle journal 24 for being associated with axle 11 changes to section bars 21.According to the present invention, region of variation
31 extend to the load area 32 of axle 11.More precisely, region of variation 31 in axial direction at least extended on axle 11 by
In the region of the load cell 16 of arrangement.In general, load area is the outmost portion of multiple outmost load cells
/ region, be the region between outmost cylinder herein.In practice, the cross-sectional profiles of axle are so that people's will
Outer mode changes in roll end, in these roll ends, and a load cell or multiple load cells are in and smoothly changed
Become in the region of its shape, outside the standard cross-section facial contour of axle.In figs. 3 and 4, region of variation 31 in axial direction exists
Extended on two to three axles 11 in the region of load cell be arranged, outmost.Therefore, with known solution
Compared to significantly extending region of variation.In general, the length s of region of variation 31 in axial direction is the diameter R's of axle 11
0.4-1.6 times, preferably 0.6-1.2 times.Here, axle is also enhanced on the load-bearing capacity of quality.In practice, peak stress quilt
Set relatively low and be more evenly distributed for larger region, and the Quality Down of axle simultaneously.Additionally, it is smooth and
Fusiform shape is more favourable in foundry engieering.More precisely, region of variation is smoothly raised.
The opening 33 cast to end section 19 is shown on Fig. 3 and Fig. 4 left-hand end, the opening is from axle journal 24
End extends up to region of variation 31.Corresponding opening is also in opposite end section 20.The opening unloads axle
(entlastet) and can be additionally implemented easily into by the opening inside roller insertion guiding.Preferably, opening 33 exists
Opened wide in region of variation 31 on the opposite both sides of section bars 21.This for example causes insertion guiding, such as load cell
The guiding of flexible pipe becomes easy.Additionally, the cross section of axle journal 24 can be (Fig. 3) or polygonal of traditional rotation-symmetric
(Fig. 4).Here, the shape of axle journal can be with optimised, and turning is may be implemented as the machining needed for the support
Processing.Due to smooth and long region of variation, raised end section does not require machining.Therefore, machine is carried out to axle
The requirement of processing becomes less.
Therefore, to allow the unexpected mode of people to be used to the end section of axle shorten the section bars, its mode is to hold
The region of variation 31 of portion's section 19 and 20 is extended to the load area 32 of roller 11 and 18.In other words, region of variation 31 is at least
Extend in the region of outmost load cell 16, be herein outmost load cylinder region in.Here, axle
Crossbeam is longer than common on the position, because in the case of known axle, section bar part therefrom portion's observation than load circle
Cylinder stretches out farther (Fig. 1).In a solution in accordance with the invention, the outmost load cylinder of support of axle
Part can be radially kept than crossbeam more outward in same area.The load to roller of the region of variation of end section
The extension in portion can be realized smaller than before in axle journal and end section region but is distributed than before broader
Stress.Here, also saving the weight for the structural member mentioned compared with the end section that great-jump-forward changes.
The axle 11 shown in Fig. 4 has additional rib 23 on the cross-sectional profiles of section bars 21 so that axle 18
Bending resistance is bigger than the situation of not additional rib 23.In other words, the cross-sectional profiles and axle in the section bars of axle
End section cross-sectional profiles it is different.These end sections have axle journal 24, and it includes being used for the supporting arrangement
Mating surface 25.Mating surface 25 changes to the section bars 21 with I profiles, and the section bars have additional rib 23.Due to
Additional rib, the bending resistance increase of axle.In other words, axle than front curve obtain less, wherein, by using described attached
Plus rib, remaining size arrangement of roller pair keeps constant, although these rollers are extended.Here, avoiding additional chi
Very little arrangement and machining.
Preferably, the yardstick of additional rib 23 is selected so that the bending resistance of axle 18 is than not additional rib
23 situation big 25%-75%, preferably 35%-55%.By the relatively little of raising of bending resistance, reach required
Security border.
Figure 4 illustrates another axle according to the present invention.Herein, equipped with the pars intermedia 26 of additional rib 23
The section bars 21 are associated with the adjustment region 28 of the adjacent region of variation 31 on its side.Here, axle has maximum
Rib.End sections are standard to a certain extent for suitable size, and the intensity of section bars is therefore total
It is to be changed according to selected additional rib and its length.In Fig. 3, section bar part is so-called common section bars
Point, not figure 4 illustrates additional rib.In Fig. 4, in adjustment region 28, the cross-sectional profiles of axle 18 are from section bar
The change of part 26 to end sections 27 is linear.Here, the cross-sectional profiles of axle little by little change step by step, wherein, can
To avoid local peak stress.Preferably, in adjustment region 28, the cross-sectional profiles of axle 18 are from section bar part 26 to end
The change of part 27 is almost tangent.Here, the stress distribution for the axle being bent ideally becomes without big stress concentration.
Additionally, the metal of melting can unobstructedly flow.
Additional rib is arranged in the intermediate region of the section bars of axle.More precisely, additional rib 23 is big
Cause is arranged in the region of jaws 29.For example in six meters of long axles, additional rib for example can be with two marginating compartments
Open a meter and be arranged in middle part, or from middle part towards two edge directions two meters are arranged for example in the larger roller of load.Usually
Say, the path of the additional rib of axle is longer, and axle is harder.Except length is outside one's consideration, the size of additional rib can also be changed
Become.Exactly, the type of mold can be used in additional rib by the adjustment to length, to constitute the tune
Main plot domain.Therefore, can be by means of two different additional molds, in no hand labour or new chi in addition to traditional mold
In the case of the processing to mold of very little arrangement, the casting rigidity axle different with length.Meanwhile, the He of end section 19 of the axle
20 can be constant in the case of shaft diameter identical.
It is new and make one the mold unexpectedly added by cast molding deviceConstitute, its
Traditional mold is covered in a part for the extension.In other words, except end section and the section bars with basic configuration
Exceptionally, the currently available cast molding device of oneself.By means of mold group, adjustment contouring and additional rib are constituted on axle
Profile.It therefore, it can the connection by least end, adjustment portion and additional reinforcement facility at least from the mold group of three kinds of forms
Part includes the mold of whole roller to constitute according to the present invention.By means of the mold group that can be adjusted, the cross-sectional profiles of axle are bright
It is aobvious to change, discharge, several millimeters of long deviations correlation of traditional attribution in this and cross-sectional profiles to casting.In practice
In, the change is tens millimeters.
The axle according to the present invention is show in cross section in fig. 2.On the left side of the main shaft of axle 18, by means of thin modeling
Stockline (Kunststofflinie) shows the additional rib 23 according to the present invention, and the crossbeam 30 on right side keeps not having
Additional rib.Herein, additional rib 23 is arranged on the inner surface of crossbeam 30 for being associated with I profiles.Therefore, crossbeam
Top can be identical on all axles, and additional quality inwardly occur.Preferably, additional rib formed objects ground cloth
Put on two crossbeams.The characteristic of axle can be adjusted by the different size of additional rib on these crossbeams.Usually
It was determined that the axle has I profiles, the I profiles include entablature and sill.Connecting plate is located between these crossbeams.It is additional
Rib is the rib being made up of enlarged portion, and the rib is the inside thickening part in preferably radially direction of I profiles.Although
Transversal in Fig. 2 b is different, additional rib be the fixed part of axle and the additional rib when casting the axle by into
Type.
Therefore the present invention is directed to the roller equipped with casting axle of fiber web machine.Roller 10 or 14 is associated with what can not be rotated
Axle 11 or 18, the axle that can not be rotated is associated with two end sections 19 and 20 and between these end sections 19 and 20
Section bars 21.In most cases, the basic configuration of the cross-sectional profiles of the section bars is I.This in section bars 21 is transversal
The additional rib 23 is designed under facial contour so that the bending resistance of axle 11 or 18 is more than the feelings without additional rib 23
Condition.In addition, the axle corresponds to content described above.
By means of the characteristic of the region of variation of axle, the additional rib of axle or both, the application of the roller can be widened
Field, and without selecting larger roller size or counter roller larger in addition.Also there is no the requirement arranged size or at least
Significantly tail off, which reduce cost.Additionally, additional rib assigns the more bending resistances of axle with small change.In practice,
The requirement being machined to axle is tailed off, and axle journal can also be machined by turning.Only change
Be the blank produced by casting.The increase of quality is also limited, because the profile of the axle is only at one of extension
Changed on point.The formation of additional rib requires few additional resource, because must only be purchased for existing mold group
Put the mold for adjustment region and the second mold for centre portion.Correspondingly, the smooth region of variation of end section
It is favourable and its requirement to machining is seldom.
In practice, a mould can be made in cast frame by means of the mold of the foregoing description, the institute in the mould
Axle is stated disposably to be cast as.Mechanical treatment needed for being performed after removing cast frame to surface, then, the axle is ready for
It is used on equipment and connects the roller set to constitute the roller of compensated bend.
