The known casting axis 18 of the roller for fiber web machine is shown in Fig. 2 b.Shown axis 18 can also be by
It is configured to the pressing axis 11 of boots roller 10.In figs. 3 and 4, axis 11 is attached there are two end section 19 and 20.In these ends
Section bars are disposed between section 19 and 20, the cross-sectional profiles of the section bars are I in its basic configuration at this.Along axis
Cross-sectional profiles major axes orientation, axis bearing load well, although " waist " of the profile is narrow.Shown with imaginary point line
Main shaft out.The partial response outside of the crossbeam of I profile is in the set, i.e., these crossbeams are raised in end, wherein axis
Shape corresponding to circle shape roller cover inner surface configuration.Additionally there are also recessed portions 22 in another crossbeam, in the recess
Load cell is disposed in portion.The supporting arrangement of roller set supports on axis two ends, and load cell is arranged substantially at
In the length for the axis being entirely formed.It therefore, can the spacing between holding shaft and roller set and can also be with as expected
Adjust desired profile.If roller is in lower position, it be stressed that the curved conspicuousness of axis, wherein the axis
It is not only due to load and is bent and is bent due to self weight.
Axis 11 according to the present invention is shown from side in figures 3 and 4.Each end section 19 and 20 is configured with change
Change region 31, in the region of variation, the axle journal 24 for being associated with axis 11 changes to section bars 21.According to the present invention, variation zone
Domain 31 extends to the load area 32 of axis 11.More precisely, region of variation 31 in axial direction at least extends on axis 11
In the region for the load cell 16 being arranged.In general, load area is the outmost of multiple outmost load cells
Region between part is the region between outmost cylindrical body herein.In practice, axis cross-sectional profiles so that
The unexpected mode of people changes in roll end, and in these roll ends, a load cell or multiple load cells are in smooth
Ground changes in the region of its shape, except the standard cross-section facial contour of axis.In figs. 3 and 4, region of variation 31 is along axial direction
Direction extends in the region of load cell be arranged, outmost on two to three axis 11.Therefore, with it is known
Solution extends region of variation compared to significant.In general, the length s of region of variation 31 in axial direction is axis 11
0.4-1.6 times, preferably 0.6-1.2 times of diameter R.Here, axis is also enhanced about the load-bearing capacity of quality.In practice,
Peak stress is set to lower and is more evenly distributed for biggish region, and the quality decline of axis simultaneously.It is additional
Ground, smooth and fusiform shape are more advantageous in foundry engieering.More precisely, region of variation is smoothly raised
's.
The opening 33 cast to end section 19 is shown on the left-hand end of Fig. 3 and Fig. 4, the opening is from axle journal 24
End extend up to region of variation 31.Corresponding opening is also in opposite end section 20.The opening unloads axis
(entlastet) and additionally the perforation guidance that can be implemented easily by the opening inside roller.Preferably, opening 33
It is opened wide on the opposite two sides of section bars 21 in region of variation 31.This for example makes perforation guidance, such as load cell
The guidance of hose become easy.Additionally, the cross section of axle journal 24 can be the (Fig. 3) or polygonal of traditional rotation-symmetric
Shape (Fig. 4).Here, the shape of axle journal can be optimised, and it may be implemented as vehicle for machining needed for the support
Cut processing.Due to smooth and long region of variation, raised end section does not require machining.Therefore, machine is carried out to axis
The requirement of device processing becomes less.
Therefore, the end section of axis can be used to shorten the section bars in a manner of keeping people unexpected, mode is,
The region of variation 31 of end section 19 and 20 is extended to the load area 32 of roller 11 and 18.In other words, region of variation 31 to
It extended in the region of outmost load cell 16 less, be in the region of outmost load cylindrical body herein.Here,
The crossbeam of axis is longer than common on the position because in the case where known axis, profile part therefrom portion's observation than negative
Lotus cylindrical body extends outwardly farther (Fig. 1).In a solution in accordance with the invention, the outmost load circle of the support of axis
The part of cylinder can radially be kept than crossbeam more outward in same area.The region of variation of end section arrives
The extension in the load portion of roller can be realized in axle journal and end section region it is smaller than before, but compare before
It is distributed broader stress.Here, also saving the weight for the structural member mentioned compared with the end section of great-jump-forward variation.
Axis 11 shown in Fig. 4 has additional reinforcement part 23 on the cross-sectional profiles of section bars 21, so that axis 18
The case where bending resistance ratio does not have additional reinforcement part 23 is bigger.In other words, the cross-sectional profiles and axis in the section bars of axis
End section cross-sectional profiles it is different.These end sections have axle journal 24 comprising are used for the supporting arrangement
Mating surface 25.Mating surface 25 changes to the section bars 21 with I profile, which has additional reinforcement part 23.Due to
The bending resistance of additional reinforcement part, axis increases.In other words, the front curve of axis ratio obtains less, wherein by using described
Remaining size arrangement of additional reinforcement part, roller pair remains unchanged, although these rollers are extended.Here, avoiding additional
Size arrangement and machining.
Preferably, the scale of additional reinforcement part 23 is selected, so that the bending resistance ratio of axis 18 does not have additional reinforcement part
23 the case where big 25%-75%, preferably 35%-55%.By the relatively little of raising of bending resistance, have reached required
Safety boundary.
Another axis according to the present invention is shown in FIG. 4.Herein, equipped with the middle part of additional reinforcement part 23
26 and the adjustment region 28 of adjacent region of variation 31 is associated with the section bars 21 on its side.Here, axis has maximum
Reinforcement part.End sections are standard to a certain extent for suitable size, and the intensity of section bars is therefore
Always changed according to selected additional reinforcement part and its length.In Fig. 3, profile part is so-called common profile
Part, the not additional reinforcement part shown in Fig. 4.In Fig. 4, in adjustment region 28, the cross-sectional profiles of axis 18 from
Profile part 26 to the change of end sections 27 be linear.Here, the cross-sectional profiles of axis gradually change step by step,
In, it can be to avoid the peak stress of part.Preferably, in adjustment region 28, the cross-sectional profiles of axis 18 are from profile part 26
Change to end sections 27 is almost tangent.It is answered here, ideally becoming not big by the stress distribution of curved axis
Power is concentrated.Additionally, molten metal can unobstructedly flow.
Additional reinforcement part is arranged in the intermediate region of the section bars of axis.More precisely, additional reinforcement part 23 is big
Cause is arranged in the region of clamping opening 29.Such as in six meters of long axis, additional reinforcement part for example can be with two edges interval
It opens a meter and is arranged in middle part, or arrange two meters from middle part towards two edge directions for example in the biggish roller of load.Generally
It says, the path of the additional reinforcement part of axis is longer, and axis is harder.Except length is outside one's consideration, the size of additional reinforcement part can also be changed
Become.Exactly, the type of mold can be used in additional reinforcement part by the adjustment to length, it is described to constitute
Adjustment region.Therefore, in addition to traditional mold can by means of two different additional molds, in no hand labour or
In the case where the processing to mold of new size arrangement, the casting rigidity axis different with length.Meanwhile the end region of the axis
Section 19 and 20 can be constant in the identical situation of shaft diameter.
It is new and make one unexpected additional mold by cast molding deviceIt constitutes,
Traditional mold is covered in a part of the extended segment.In other words, except end section and with the profile of basic configuration
Part is outer, oneself currently available cast molding device.By means of mold group, constituted on axis adjustment contouring and it is additional plus
Strong contouring.Therefore, at least end, adjustment section and additional reinforcement facility can be passed through at least from the mold group of three kinds of forms
Connector constitute the mold according to the present invention including entire roller.By means of the mold group that can be adjusted, the cross section of axis is taken turns
Exterior feature is appreciably changed, the discharge of traditional attribution in this and cross-sectional profiles to casting, several millimeters long of deviation it is related.
In practice, which is tens millimeters.
Axis according to the present invention is shown in cross section in figure 2b.On the left side of the main shaft of axis 18, by means of thin
Plastic cord (Kunststofflinie) shows additional reinforcement part 23 according to the present invention, and the holding of crossbeam 30 on right side does not have
There is additional reinforcement part.Herein, additional reinforcement part 23 is arranged on the inner surface for the crossbeam 30 for being associated with I profile.Therefore, horizontal
The top of beam can be identical on all axis, and additional quality inwardly occur.Preferably, it is identical big to add reinforcement part
It is arranged on two crossbeams smallly.The characteristic of axis can be adjusted by the different size of additional reinforcement part on these crossbeams.
Generally it was determined that the axis has I profile, which includes upper beam and lower beam.Connecting plate be located at these crossbeams it
Between.Additional reinforcement part is the reinforcement part being made of enlarged portion, which, which is that the preferably radially direction of I profile is inside, adds
Thick portion.Although transversal in Fig. 2 b is different, additional reinforcement part is the fixed part of axis and the additional reinforcement part described in the casting
It is formed when axis.
Therefore the present invention is also related to the roller equipped with casting axis of fiber web machine.Roller 10 or 14, which is associated with, not to be able to rotate
Axis 11 or 18, the axis not being able to rotate attach there are two end section 19 and 20 and these end sections 19 and 20 it
Between section bars 21.In most cases, the basic configuration of the cross-sectional profiles of the section bars is I.In being somebody's turn to do for section bars 21
The additional reinforcement part 23 is designed under cross-sectional profiles, so that the bending resistance of axis 11 or 18 is greater than without additional reinforcement part 23
The case where.In addition, the axis corresponds to content described above.
By means of the characteristic of the region of variation of axis, the additional reinforcement part of axis or the two, the application of the roller can be widened
Field, and do not have to select biggish roller size or furthermore biggish counter roller.Also there is no the requirement to size arrangement or at least
It significantly tails off, which reduce costs.Additionally, it adds reinforcement part and assigns the more bending resistances of axis with small change.It is practicing
In, the requirement being machined to axis tails off, and axle journal can also be machined by turning.Only occur
What is changed is the blank generated by casting.The increase of quality is also to be limited, because the profile of the axis is only in extended segment
It changes in a part.The formation of additional reinforcement part requires few additional resource, this is because being directed to existing mold group
The mold for adjustment region and the second mold for centre portion must only be purchased.Correspondingly, the smooth change of end section
Change region is advantageous and its requirement to machining is seldom.
In practice, a mold can be made in cast frame by means of the mold of the foregoing description, the institute in the mold
Axis is stated disposably to be cast as.Mechanical treatment needed for executing after removing cast frame to surface, then, the axis are just quasi-
It is ready for equipping and connecting roller of the roller set to constitute compensated bend.
