Description

Bendable cylinder
Technical field
The present invention relates to a kind of bendable cylinder, be particularly related to and be used for the extensor that mesh material extends, described cylinder comprises the continuous tubular cylinder shell of composite and fixing axial region, on this stationary axle, described barrel shrond is equipped with bearing, and cylinder also comprises the bending apparatus that is used to make the barrel shrond bending.
Flexible combinatorial cylinders with composite shell is particularly useful as paper machine and the extensor of making in the board and box lining machine.Combinatorial cylinders has excellent material characteristic, particularly elasticity coefficient and density, therefore, can design its size and relatively easily bend to desirable curvature to cause it.
Background technique
Specification FI-B-103 071 discloses a kind of bendable cylinder that is used for mesh material, the tubular cylinder shell that this bendable cylinder comprises composite be connected with any end of this barrel shrond fixing be irrotational spindle.Described spindle is secured on the fastening flanged structure that is fixed on the machine frame by two fulcrums.Cylinder also comprises bending apparatus and control apparatus, and described bending apparatus is positioned at the outside of barrel shrond, and is used to make spindle and barrel shrond to be bent into arch; Described control apparatus allows the angular orientation of cylinder arch to be conditioned.
Be the structure and the installation of relative complex according to the shortcoming of the scheme of this specification.In addition, its side at barrel shrond has occupied big relatively space.And in existing scheme, it is the work of a complexity and difficulty that the bearing of utilization between spindle and barrel shrond realized suspending, especially when mounted.
Summary of the invention
The objective of the invention is to overcome the shortcoming of prior art, and a kind of novel combinatorial cylinders structure fully is provided.In structure of the present invention, therefore two Bearing Installation have made very compact and simple bending system in the sheath that is arranged at the barrel shrond inboard.This bending system can be easily mounted to the inboard of barrel shrond as a unit module.
In claims, at length narrated technological scheme feature of the present invention.
Description of drawings
Below, will describe the present invention with accompanying drawing in conjunction with the embodiments, wherein:
Fig. 1 shows according to combinatorial cylinders of the present invention;
Fig. 2 shows according to second combinatorial cylinders of the present invention; With
Fig. 3 shows according to the 3rd combinatorial cylinders of the present invention.
Embodiment
Fig. 1 shows the side sectional view of the end of combinatorial cylinders, this combinatorial cylinders comprises the continuous barrel shrond 1 of composite, and the central shaft 2 in this barrel shrond 1, this central shaft passes described barrel shrond and has thicker middle part 21 and thinner end 22 (inside) and 23 (outsides).
Be sheath 30 (outside axle bush) between interior axial region 22 and shell 1, this sheath almost completely is assemblied in the barrel shrond inboard.Described sheath is fixedly mounted in the inboard of barrel shrond 1 and is positioned at the end of barrel shrond 1. Bearing 31 and 32 is installed in the inboard of sheath 30 and at its arbitrary end, at bearing 31 and 32 inboards axle bush or lasso 33 (inner axle bush) is arranged, and this axle bush almost completely is assemblied in the barrel shrond inboard.And cylinder has the bending apparatus that is arranged in the axle bush 33, and this bending apparatus is used for crooked axle bush 33 and barrel shrond 1 and is used to regulate flexure operation.For this purpose, the outboard end of axle bush 33 has adjusting screw 5, and this adjusting screw 5 is connected with the end of axial region by screw thread 4.And the inner end of axle bush 33 rotatably is connected with axial region 22 by ball bearing 6.Regulate the tortuosity of cylinder (size of curvature) by screwing adjusting screw 5, change the angular orientation between axial region 22 and the axle bush 33 thus, and because the bearing 31,32 that moves through of axle bush 33 is transferred to housing parts 1, so the angular orientation between shell 1 and the axial region 2 also is changed simultaneously.
In the solution of the present invention, near the inside edge of axial region 22, another inboard bearing 31 also is set between sheath and the barrel shrond, be positioned at the position of aiming at ball bearing 6, therefore this whole bearing and bending system have formed an independent unit module 3, and this module 3 can be installed in the inside of barrel shrond.
And cylinder comprises the have rocker bearing turbine 7 of (rocker bearing), and this turbine 7 is installed in the end of axle, to allow to change the direction of arch.In Fig. 1, by bearing power by bending.In theory, the other end is same, and just the axial force in bearing means is released in the structure of being discussed.
Fig. 2 and Fig. 3 show according to other bendable cylinders of the present invention, and wherein, the cylinder among Fig. 2 also has the axle that passes this cylinder and at the turbine 8 of this shaft end.And the cylinder among Fig. 3 has spindle 9, and this spindle 9 has thicker interior section 92 and thinner exterior section 93, and cylinder also has the turbine 10 in the end of spindle in addition.In the scheme of Fig. 3, bending force is transferred on the framework fully, and in Fig. 2, bending force is dispensed between axle and the framework.
Obviously, to those skilled in the art, different embodiments of the invention are not limited to above-mentioned example, and it can have multiple variation in claims institute restricted portion.
