The action direction is basically opposite to paired pressing elements; the roller sheath and the paired pressing elements form a contact surface together; and the breadth of a fiber material can be treated in the contact surface. In order to prevent overstress occurring on the roller sheath beside the contact area, a thrust bearing for the roller sheath is arranged on the supporting device or is connected with the supporting device; and the when the thrust bearing has radial load on the roller sheath (especially in the area of the circumferential section), the axial clearance for the roller sheath is released.
Description
Technical field
The utility model relates to a kind of boots formula pressure roller, and this boots formula pressure roller comprises the flexible roller sheath that extends around static support.
Background technology
This device is for example used at squeezer that is used for the processing of paper conversion and cardboard or calender field.Following explanation relates to wide roll gap calender, but the utility model is not limited to this device.
(this roller defending party to the application sells with the title of " NopcoFlex roller ") is prone to curved roller sheath and guides on circuit orbit through the tension disk of side in boots formula pressure roller.The inner clamping element of roller is recessed boots portion, and its lubricating pad through hydrostatic and/or hydrodynamic pressure makes and is prone to curved roller sheath and matches compressing member (normally counter roller) relatively and compress.Therefore the roller sheath is followed the geometry and the same lowland bending of boots portion in the zone of boots portion.
What the roller sheath was fixing is stretched in the sheath edge through realizations such as clamping devices.Therefore, the roller sheath remains protruding in tensioned portion, and is just circular.In the transition that on the interval of edge regulation, proceeds to recessed boots formula geometry.This causes improve and tensioning state multiaxis in the roller sheath.When the bending stiffness of roller sheath increased, the problem of curve transition also increased, and made to cause high failure risk owing to the crackle on the roller sheath forms.
In order to reduce undesirable stress, used a kind of annex at DE19645407A1.The roller sheath is installed in tension disk or is also referred to as on the bracing or strutting arrangement at this in this end in its rubber-like radial motion free degree.Because freedom of motion radially, roller sheath also can be complementary with the axial end portion of the flat profile that supports boots under pressure.But this improvement is not enough in many cases.If sheath is made of plastics, the longitudinal stress in the contact area is on the side direction next door, and just the axially-extending portion in boots portion becomes big like this, makes that sheath is torn.If sheath is processed by thin steel plate, fold that no longer can be smooth on the circumference of so necessary consideration boots formula pressure roller.
Summary of the invention
Therefore, the utility model technical problem to be solved is to prevent in the roller sheath, by contact area, to occur the stress of transition.
This technical problem solves through a kind of like this boots formula pressure roller; This boots formula pressure roller comprises the flexible roller sheath that extends around static support; This roller sheath is bearing on the support of roller through bracing or strutting arrangement respectively in its two axial end region with rotating mode; And the boots portion that comprises the supporting surface that at least one has the inboard that is used for the roller sheath, said boots portion action direction on the circumferential part section of roller sheath is relative with the pairing clamping element basically, and the roller sheath forms contact-making surface with said pairing clamping element; The fibrous material breadth can be processed in this contact-making surface; Wherein, the thrust bearing that is used for the roller sheath is arranged on the bracing or strutting arrangement and perhaps is connected with bracing or strutting arrangement, and this thrust bearing discharges the end play that is used for the roller sheath in (especially in the zone in the circumferential part section) on the roller sheath when radial load is arranged.
This end play makes the roller sheath can avoid too high stress.On near the transitional region of the concave portions (mainly being the boots portion) of sheath, sheath bears high tension and shear stress usually.Now, sheath can overcome described possibility through the utility model, therefore can avoid stress.
Advantageously, the end play of roller sheath only is released in the zone of circumferential part section.This causes sheath not have end play ground on bracing or strutting arrangement, to guide reliably in the major part of its circumference.Avoid the vibration of sheath when high peripheral speed in this way.
The roller sheath preferably supports on radial elastic ground.Pass through equably through bending under the stress that the depression of sheath process in the circumferential area of boots portion can be avoided occurring through being suspended on of radial elastic and the situation of crooked cyclic deformation until the edge.
The roller sheath preferably is bearing on the elastic ring diametrically.This ring is easy to be fixed on the circular periphery of bracing or strutting arrangement.Can consider various enforcement modification, the ring that the ring of for example being processed by rubber is perhaps processed by the flexible pipe of filling with compressed fluid.This while can be born sealing function.Avoided the compressed fluid and the lubricating fluid of hydrostatic and/or hydrodynamic pressure to flow out effectively from roller.
Advantageously, the radial motion through the roller sheath discharges end play.Guaranteeing through this function, just is also to increase the free space that is used for sheath because the place of maximum stress appears in the power (for example on counter roller) of radial effect.
If it is favourable that the bearing surface taper of thrust bearing ground extends.Now, make that with simple especially mode the depression of the journal bearing of the relative radial elastic of sheath is big more, the end play of sheath is also big more.
Roller sheath end is contained in the groove of the outer ring that preferably can divide.Can realize the sealing of roller inner chamber more simply by means of this outer ring with corresponding stiffness.With being connected of bracing or strutting arrangement can be through the realization that simply is threaded.
Advantageously, except that the roller sheath, elastic ring also is contained in the groove.Therefore having created one for flexibly mounted sheath bearing can be from the maintenance purpose by the construction unit of changing easily.
Particularly advantageous is between sheath and elastic ring, torque transmitter to be set.For example the external tooth of sheath is rabbeted in the internal tooth of outer ring recess.Sheath is pressed by the power radial inward of counter roller in the zone of boots portion and from engagement, is deviate from.Created end play for sheath in this respect, so that compensation stress.The overwhelming majority at the roller circumference has guaranteed in sheath, not occur reversing through torque transmitter reliably.
Description of drawings
Followingly specify the utility model with reference to accompanying drawing according to embodiment.The signal longitdinal cross-section diagram that passes by the roll end of the boots formula pressure roller of the utility model has been shown in Fig. 1.
The specific embodiment
Boots formula pressure roller 1 has static support 2, and this support is bearing in the framework with not shown but known mode.The bracing or strutting arrangement 3 that is used for flexible roller sheath 4 is bearing in said support with rotating mode through at least one bearing 5.Boots portion 6 on the support 2 is supported in the roller.Counter roller 10 effects that boots portion 6 is shown in dotted line relatively.That boots portion has is recessed, with the suitable bearing-surface 7 of counter roller, boots portion can compress the relative counter roller 10 of the circumferential part section of sheath 4 through this bearing-surface.The bearing-surface of boots portion can have 30 to 500mm length along the roller circumferencial direction.Bearing-surface is long more, and it is just dark more that roller sheath 4 will insert recessed arching portion at the center, and this arching portion is corresponding to the profile of counter roller 10.
In order to follow said shape better, roller sheath end 8 is resisted against in the groove 12 of the outer ring 11 on the elastic ring 9.This ring 8 is the flexible pipe of filling with compressed fluid in this embodiment.From the supporting force of external action on sheath, sheath is inwardly motion radially through counter roller 10, and elastic ring 9 (flexible pipe) is from the oval shape of the shape boil down to of its circle.Elastic ring 9 is yielded to this pressure and is made sheath 4 follow the recessed shape of supporting surface 7.Certainly, elastic ring also can have multiple other shape of cross section, and the flexible pipe that alternative pressure is filled is processed by elastomeric material.Also can consider a plurality of single springs that are distributed on the circumference.
In addition, sheath and outer ring have the bearing surface 13.1,13.2 of two axial action, and said bearing surface forms thrust bearing 13 jointly.Because said complementally is shaped to taper each other, opened end play 15 through the radial motion inwardly of roller sheath.Because this gap, the roller sheath stress in the circumferential area of boots portion obviously is reduced.
On the circumferential section of the overwhelming majority, the bearing surface 13.1,13.2 of axial action is positioned at before the circumferential area of boots portion with afterwards and prevent rocking of roller sheath 4, because axially no longer including the gap at this.Regulation is only created end play 15 at the circumferential area of boots portion wittingly.
In order also to prevent reversing and guaranteeing uniform revolution of sheath, be provided with a torque transmitter 14.For this reason, in this embodiment, outer ring 11 is equipped with internal tooth 14.1, and sheath is equipped with external tooth 14.2.Because outer ring 11 is fixedly connected with bracing or strutting arrangement 3, and roller drives with not shown but known mode through in these two structure members at least one, and driving torque directly is passed on the sheath in the major part of roller circumference at least.Two teeth only intercouple at the circumferential area of boots portion.
