Definitions
- the invention relates to a double-disc seal for top rollers on drafting systems according to the preamble of claim 1.
- the interior of the roller housing which usually comprises a roller bearing, is sealed against fiber fly from the ambient air, as is known, for example, from DE 40 39 804 AI or DE 195 09 055 Cl.
- the seals shown there consist of a one-piece U-shaped sleeve with flanges on both sides. It creates its sealing effect on the one hand from the two sealing gaps formed by the flanges to the outer ring bore and on the other hand through the cavity between the two flanges in which the fibers and dirt particles that have penetrated through the outer sealing gap can collect and through the internal sealing gap from further penetration be held in the rolling bearing.
- Such seals are simple and inexpensive to manufacture and assemble. The assembly can be carried out with automated assembly devices.
- one of the two flanges must be cut slightly smaller in diameter than the other. This leads to different sealing gap widths. Due to the tolerances when manufacturing the diameters and the possibility of runout errors between the bore and the flange, a safety surcharge is usually applied Sealing gap is taken into account in order to reliably avoid touching or streaking of the flanges in the bore of the roller housing and thus to ensure a non-sliding seal. In an environment that is extremely contaminated with fiber fly and dust, it can therefore occasionally occur that the sealing effect is impaired by a relatively large sealing gap and that so much dirt collects in the cavity formed by the flanges of the sleeve that the roller housing is slightly hindered in its rotation or even is braked inadmissibly.
- the generic DE-AS 15 10 922 describes seals with spring washers pressurized in the axial direction, an externally centered washer followed by an externally centered washer with a large internal gap.
- the radially movable sealing washers are fixed by the axially applied pressure. In this way, an extremely small sealing gap between the sealing washers and the roller housing can be achieved.
- the double-disc seal according to the invention with a further sealing gap upstream of the external sealing gap, there are no malfunctions caused by axial forces which act on the sealing disc from the outside when the winding is formed.
- the double-disc seal can be installed automatically in a simple manner. Both the manufacture and the assembly of the double disc seal can be carried out cost-effectively. A certain side orientation of the double-disc seal is not necessary during assembly. Identical double disc seals can be used at both ends of the axis. A production and stocking of different designs is therefore not necessary in the double-disc seal according to the invention.
- Support elements according to claim 6 need only be manufactured in a single version. This reduces the number of different parts required and to be produced for the double-disc seal according to the invention.
- roller body 1 is a top roller twin, the roller body each having a double disc seal according to the invention, partially in section,
- Fig. 4 shows an embodiment of the double disc seal with two support elements designed as an angle ring in an enlarged sectional view.
- the top roller twin 1 shown in FIG. 1 has two roller bodies 2, 3 which are mounted on a common continuous axis ⁇ by means of roller bearings 4, 5.
- a saddle 8 is formed on the axis 6, on which the axis 6 is held by a conventional holder.
- the interior of each roller body 2, 3 is sealed against contamination by a double disk seal 7, 7A according to the invention.
- the support element for the sealing disk 9 is designed as an angle ring 10, the disk-shaped part 11 serving as a stop for the sealing disk 9.
- the sleeve-shaped part 12 of the angle ring 10 has a stop surface 13 to which a support element designed as a disk 14 is inserted and fixed by caulking.
- the disk 14 forms the stop for the sealing disk 15.
- Sealing disk 9 and sealing disk 15 are identical in construction.
- the sealing disks 9, 15 are acted upon by a helical spring 16 with compressive force in the axial direction.
- the sealing disk 9 is pressed against the disk-shaped part 11 of the angle ring 10 and the sealing disk 15 against the disk 14.
- the spring force fixes the sealing disks 9, 15 in the required centered operating position, but leaves a slight one New centering at any time.
- the helical spring 16 is made of round wire, the wire diameter and number of turns of the helical spring 16 being selected so that the helical spring 16 can be preloaded in such a way that its length is somewhat less than the distance between the two pressed-on sealing washers 9, 15.
- the inner diameter of the helical spring 16 is selected so that it has only a slight radial play with the sleeve-shaped part 12 of the angle ring 10. In this way, the spring turns form an almost gapless surface, which makes assembly easier.
- the sealing disks 9, 15 each form a very narrow sealing gap 17, 18 with the roller body 2.
- the outside diameter of the disk 14 and the outside diameter of the disk-shaped part 11 of the angle ring 10 are only slightly smaller than the outside diameter of the sealing disks 9, 15 the roller body 2 has an inner diameter of 16.18 mm, while the outer diameter of the sealing disk 9, 15- 16.15 mm each and the outer diameter of the disk 14 and the disk-shaped part 11 are each 15.97 mm.
- the further sealing gap 19, 20 between the disc 14 and the disc-shaped part 11 is thus also narrow and prevents the sealing function of the double disc seal 7 from being permanently impaired when the axis 6 is formed.
- the angle ring 10 has a chamfer 21, 22 at each end.
- the chamfer 22 is essentially formed when the disc 14 is caulked.
- the chamfers 21, 22 facilitate centering of the double-disk seal 7 when pressed onto the axis 6.
- the sealing disk 9 To assemble the double-disk seal 7, the sealing disk 9, the helical spring 16 and the sealing disk 15 are placed one after the other on the sleeve-shaped part 12 of the Angle ring 10 pushed on and then the disc 15 joined to the stop surface 13 and fixed by caulking. The assembly thus created is pressed onto the axis 6 and pushed so far in the direction of the saddle 8 that the roller body 2 can be tilted in the end region of the axis 6 to fill in the balls of the roller bearing 4.
- the double-disc seal 7 designed as an assembly is pressed back in the direction of the end of the axis 6 or in the direction of the roller body 2 until it has reached its operating position and can perform its sealing function. All assembly steps can be carried out in an automated assembly process.
- the double-disc seal 7 is designed such that the assembly can be mounted non-directionally on both ends of the axis 6, that is to say without a specific alignment.
- the double-disc seal 7 and the double-disc seal 7A are identical in construction, as FIGS. 2 and 3 show. While the double-disc seal 7 is mounted on the left end part of the axis 6 in FIG. 1, the identical double-disc seal 7A is mounted on the right end part of the axis 6 in the roller body 3.
- the sealing function and the advantages of the identical design according to the invention can be fully used in both positions.
- FIG. 4 An alternative embodiment is shown in FIG. 4 with the double-disk seal 23.
- a sealing disk 25 is pushed onto the sleeve-shaped part of an angle ring 24.
- Two angle rings 24 equipped in this way are mirror images so in a connecting sleeve 26 made of elastic plastic is pressed in that its sleeve-shaped parts are held in abutting manner in the connecting sleeve 26.
- the connecting sleeve 26 has spring arms 27 at both ends.
- the connecting sleeve 26 can be produced in one piece together with the • spring arms 27 inexpensively in an injection mold and thus reduces the number of individual parts required and the assembly effort.
- the double-disc seal 23 pre-assembled as an assembly is axially symmetrical.
- This double-disc seal 23 which is mounted as an assembly, can also be mounted on the axis 6 in a non-directional manner, like the double-disc seals 7, 7A in FIGS. 1 to 3.
- the two angle rings 24 are designed such that they form tight further sealing gaps 19, 20 in cooperation with the roller bodies 2, 3.
- the double-disk seal 23 and the roller bearings 4, 5 are assembled in the same way as for the double-disk seal 7, 7A.
- the angle ring 24 can be manufactured inexpensively from sheet metal without cutting.
