Definitions
- the invention relates to a building opening shading device according to the preamble of claim 1.
- the winding shaft on which the curtain is wound up and unrolled to equip at one end with a austeleskopierbaren carrier spigot or extension piston.
- a winding shaft with a support sleeve wherein a provided with a pawl connection means is provided which prevents unwanted compression of the winding shaft.
- EP 1 568 844 A1 a telescopic winding shaft for a roller shutter.
- a locking of the two ends of the winding shaft in each case by a sliding bolt in the lateral bearing.
- the sliding bolt can be pushed up into engagement with a sleeve which is received in a form-fitting manner on the winding shaft.
- the sliding bolt on the one hand upwardly projecting pins, which are thereby pushed into recesses in the radial direction projecting pin on the sleeve to prevent rotation of the winding shaft.
- the sliding bolt has an upwardly projecting shoulder, which is thereby pushed on the inside in winding shaft axial direction in the rear grip with the radially projecting pin on the sleeve to prevent the winding shaft on a Einteleskopieren by the sleeve is held axially ,
- the winding shaft for installation in the workshop completely set - as in the EP 1 568 844 A1 explained - but to ensure during operation, ie with rotatable winding shaft, that the support piece can not be undesirable pressed into him receiving winding shaft, ie to ensure that the winding shaft is secured in operation against falling out of their storage between the two sides.
- the support piece which forms a bearing pin for suspending the winding shaft on the side part of the shutter box, is thus supported axially movable by a spring in the winding shaft or the hollow shaft, so that the winding shaft during assembly with the resilient end (the resilient extension piston) at an angle the appropriate storage on the side panel and can press with the winding shaft on the support tube, then to pivot the other, rigid front end with depressed support piece up and at the designated camp on the opposite box side part under spring force extending expansion of the winding shaft to use their original extension.
- a winding shaft with a resilient end also shows the European patent application EP 1 936 106 A2 ,
- the support piece is received axially displaceable in a pressed-in the winding shaft end bushing, and displaceable against spring force.
- a ring is provided, which can be screwed onto a thread on the carrier piece. This gland is relatively accessible. The screwing on and off with built-in winding shaft is still cumbersome.
- a similar solution with a screwed onto the extension piston retaining ring is the French patent application FR 2 934 307 A1 refer to.
- the securing device on the one hand has an axially outwardly pointing abutment surface on the front end of the hollow shaft provided with the support stub.
- the abutment surface On the other hand, on the associated side part of the hollow shaft towards projecting counter stop pin with one of Stop surface facing counter stop surface. Since the abutment surface rotates with the hollow shaft and the counterstop surface is fixed, the abutment surface is in particular annular.
- the Gegenanschlagszapfen is from a securing or locking position in which it is located at the radial height of the annular stop and compression of the rotating shaft in the operating position winding shaft (ie, a depression of the carrier nozzle in the winding shaft inside) prevented or at least limited, removable on associated side member added or movable out of its securing or locking position.
- Securing against unwanted impressions of the carrier nozzle is thus indirectly by limiting an axial direction to the side portion of possible movement of the rigid hollow shaft, in which the carrier nozzle is in turn received axially movable causes, and not directly by limiting the possibility of movement of the carrier nozzle relative to the side part or the diaphragm cap or against the hollow shaft receiving it. Nevertheless, an axial relative movement of the carrier nozzle relative to the hollow shaft is prevented to the extent that it is ensured that the support piece not so far against the bearing a bearing receiving bearing bracket or the side panel can be pressed that the winding shaft as a whole far enough telescoped to get out of their To solve the seat.
- the safety device can be designed overall easy and inexpensive. It is sufficient to provide on the hollow shaft an annular abutment surface, for example on an annular flange and on the side part, for example, a schreibnverschiebbarer bar with the counter stop pin, which can be removed for assembly purposes or preferably in the sense better Loss of security on the side part directly or at another, there fastened component, such as a bearing bearing bearing plate can be recorded out.
- a good accessibility of the fitter to be actuated by the installer of the securing device can be achieved because in the region of the side part for a downwards enough space in the winding shaft installation space to the provided with the counter stop pin component, so preferably a vertically displaceable on the side bearing part recorded safety slide, extend down to the bottom of the installation space of the winding shaft, and because on the other hand, the side bearing part and thus the safety slide with the counter-stop pin does not rotate with the winding shaft.
- the length of the hollow shaft is of course chosen in such a way with respect to the axial spacing of the side parts that a clearance exists between the hollow shaft-side stop surface and the counter stop surface.
- the counter-stop surface of the counter-stop pin is therefore also in the securing position advantageously spaced slightly from the abutment surface on the winding shaft in order to prevent rubbing of the winding shaft on the counter-stop pin.
- this will not always be preventable.
- the counter stop surface may therefore be provided with a material with a low coefficient of friction, for example plastic.
- the counter stop surface may be provided on a component which consists of such a material or is coated with such a material.
- the counter-locking pin having safety slide therefore made of plastic.
- the abutment surface may be formed on a sleeve which is mounted on the end face on the hollow shaft and which then has an end-side, axial, outwardly projecting annular flange on which the annular abutment surface is formed.
- the sleeve can advantageously be at the same time the necessary for receiving the support nozzle, recorded in the hollow shaft inner sleeve.
- the sleeve is due to the male loads as well as the support stub preferably made of a metallic material such as zinc die-casting, but could also be coated on the stop surface with plastic.
- the safety slide on which the counter-stop pin is formed is captively received on the side part directly or on a component fastened to the side part, displaceable between the securing position and one Release position in which the counterstop pin is located radially outside the annular abutment surface, that is, for example, above the provided on the hollow shaft directly or on the inner sleeve ring flange.
- the safety slide can advantageously be a plate, for example, a bearing for a bearing journal bearing support bearing plate mounted on the side part, on which the winding shaft facing side of the safety slide rests, and which is engaged behind by the safety slide. Between the plate and the side part can then be a slot into which the safety slide can engage with its plate engaging behind the section.
- the safety slide is then advantageously taken up with exclusive freedom of movement in the direction of displacement between its two positions, the release position of the securing position on the side part or on the plate attached to the side panel.
- a releasable latching connection of the safety slide with the plate connected to the side panel ie
- the bearing plate is provided, wherein the locking connection is used for releasably latching fastening of the safety slide in its locking position and thus prevents the safety slide unintentionally triggers from the winding shaft against compression securing position.
- the latching connection can also be designed so that it secures the safety slide in its release position on the bearing plate.
- the latching connection may advantageously have a projecting from the winding shaft back of the plate, for example, the bearing plate locking pin which is encompassed by two legs of a plate, for example, the bearing plate on the upper side engaging behind locking fork of the safety slide, which two legs thus simultaneously the plate, for example Can form bearing plate engaging behind section of the safety slide.
- the bearing plate engaging behind sections or the bearing plate engaging behind portion of the safety slide can be angled from a running on the winding shaft side facing the bearing plate base plate of the safety slide.
- This base plate can be configured as an annular Verliertechnischsabrough, which surrounds the bearing provided on the side part bearing and the bearing pin therein radially on the radial side and thus ensures that the safety slide does not fall even if the rear handle should solve on the bearing plate.
- the counter stop pin protrudes above the bearing from the base plate or the Verlierommesabrough of the safety slide in the axial direction, because it is particularly easy for a mechanic to operate a height-adjustable safety slide and then because of the Verlierommesabrough downwardly projecting actuating portion may be provided on the safety slide, the by the fitter only after must be moved up or down, which further facilitates access to the safety slide.
- the opening through which the bearing pin and / or the bearing is passed on the annular Verlierommesabrough of the safety slide can then advantageously be aligned with a vertical axis slot.
- the downwardly projecting operating portion is advantageous from a fitter gripped, so that no height adjustment of the safety slide tool is needed and therefore has on the underside advantageous to the winding shaft angled towards operating tab.
- the downwardly projecting actuating portion having an underside securing tab, which is angled in the opposite direction, ie away from the winding shaft and at least in the securing position on an associated, downwardly facing retaining shoulder on the bearing plate, resulting in interaction with the upper side provided on the safety slide locking fork results in an even better locking of the safety slide in its securing position.
- the actuating portion may then be formed as a bending leg, which results in a safety slide made of plastic almost by itself, which is wegzubiegbar so far with its underside of the bearing plate that the locking tab out of engagement with the retaining shoulder.
- FIG. 1 in which a generally designated 10, hollow winding shaft is shown, which is mounted at its two front ends in each case on a visor cap or on a side part 1 or 11 of the winding shaft box, not otherwise shown.
- the side parts 1, 11 may be identical, but the winding shaft 10 is supported axially fixed on the side part 11 on its tubular motor, on the other hand on the side part 1 via a Achskappenmodul with a telescopic, resiliently supported in the winding shaft support tube 6, and a attached to the visor side bearing module as will be explained in more detail below.
- FIG. 1 shown a winding shaft for a vertical awning with a round cross-section, but the invention can also be realized on a cross-sectionally polygonal winding shaft, as used for roller shutters, as well.
- the resilient axle cap module points, like FIG. 2 shows, an inner sleeve 5, 9, which is formed of two clamping bushes screwed together, an outer clamping sleeve 5 and an inner clamping bushing 9.
- inner bushing 5, 9 a via a Ausschubfeder 7 outwardly biased support sleeve 6 is included with exclusive degree of freedom in Wickelwellenachsraum over which the winding shaft 10 is supported in a mounted on the side part 1 side bearing 2, 3.
- the side bearing 2, 3 in this case has a formed as a spherical cap inner ring 2, which is mounted on the end of the carrier nozzle 6, and a bearing plate 3 which is fixed to the side part 1 and on which a bearing inner ring 2 receiving bearing outer ring 31 (FIGS. Figure 4 ) is formed.
- the support tube 6 forms together with the two clamping bushes 5, 9 and the Ausschubfeder 7 a clamping element 5, 6, 7, 9, which is guided by a designated 8 clamping bush, or the clamping bush 8 passes through and on which the clamping bush 8 in the Winding shaft 10 can be clamped.
- the inner sleeve 5, 9 formed by the two clamping bushes 5, 9 forms, together with the clamping bush 8, through which it is passed, a bushing arrangement 5, 8, 9.
- the outer clamping bush 5 has, as in FIG. 7 is shown, an outer peripheral portion having an external thread 53, which faces the inner clamping bush 9, which in turn on its outer clamping bush 5 side facing an inner peripheral portion having a corresponding internal thread 93.
- the two clamping bushes 5, 9 are thus screwed together and can move towards each other by tightening the screw in winding shaft axis direction and by loosening the screw away from each other.
- the outer clamping bush 5 has a radially outwardly projecting stop flange 52 and the inner clamping bushing 9 tapering conically in the winding shaft axis direction from the inside to the outside Outer peripheral portion or wedge portion 92 (see FIG. 8a ).
- the clamping bush 8 has a ring section 81 slotted at a slot 86, see FIG. 11 of which a plurality of concentric to the winding shaft arranged spreading or counter wedge segments 83 protrude in winding shaft axis inwardly.
- the inner peripheral side surfaces of the counter wedge segments 83 extend on a conical shape corresponding to the conical shape of the wedge portion 92 of the inner clamping bushing 9 and can spread due to the divided by segment interspaces 85 fan structure when the screw of the two clamping bushes 5, 9 is tightened and the two clamping bushes then each other move and thereby exercise on the radially projecting Antschungsflanschring 52 on the outer clamping sleeve 5 on the one hand and the conical wedge portion 92 on the inner clamping sleeve 9 on the other hand, a radially outward pressure on the counter wedge segments 83 of the clamping bush 8.
- the clamping element 5, 6, 7, 9 and the clamping bush 8 thus form a by turning on or loosening the screw of the two clamping bushes 5, 9 operable wedge gear, via which the clamping bush 8 can be pressed against the inner circumference of the hollow winding shaft 10, causing the Achschappenmodul anchor in the hollow shaft 10 total.
- the wedge angle at the conical wedge portion 92 of the inner clamping bush 9 and at the formed by the counter wedge segments 83 counter wedge portion 82 of the clamping bush 8 is chosen to be quite small, in the example shown about 10 °, with the wedge or counter wedge sections 82, 83rd extend over a relatively large axial length and almost around the entire circumference. This will only close you self-locking frictional engagement between the inner clamping bush 9 and the clamping bush 8 achieved. Beyond that, see FIG.
- FIG. 14 1 shows the clamping bush 8 has a corresponding collar engagement 84, which forms a gap in the Sp Schwarzsegmentring forming the counter-wedge portion 82 and extends up to the ring portion 81.
- the outer, rotatable clamping sleeve 5 is actuated via the support sleeve 6, which in FIG. 9 is shown in detail.
- the support piece 6 has a bearing journal or journal portion 61, with which it is supported in the spherical bearing 2, 3 side bearings 2, 3 on the side part 1.
- the bearing pin 61 in turn has an internal hexagonal recess 63 on the front side, on which a tool can be attached to the winding shaft 10 during assembly of the axle cap module.
- a support body 62 which has a conically widening axially inward outer circumference.
- a plurality of circumferentially distributed, arranged concentrically to the winding shaft axis and along the winding shaft axis extending guide grooves 75 formed radially inwardly over the circumference, which has a corresponding plurality of inner peripheral side in the radial direction inwardly projecting fins 54 at the outer clamping bush 5 is assigned, wherein the fins 54 likewise extend winding shaft coaxial, see FIG.
- the outer clamping bush 5 has, in accordance with the conical shape of the carrier body 64, on the inner peripheral side, an inner circumferential surface which conically tapers in the direction of the winding shaft axis and from which the fins 54 protrude. This results in a good self-centering of the carrier nozzle 6 in the outer clamping bushing 5 and a play-free storage, when the support sleeve 6 is biased by the Ausschubfeder 7 in its extended from the hollow shaft 10 operating position to the outside.
- the inner clamping bushing 9 also has, see FIG. 8a , a support base 91, on which the Ausschubfeder 7 can be supported with its inner end.
- the support stub 6, in contrast, has a spring guide cavity which is open toward the support bottom 91, on the axial outer side of which an inner shoulder spaced outwardly from the support base 91 in the winding shaft axis direction is located on the annular, radial wall section 65, at which the Ausschubfeder 7 with its outer end can support, whereby the support sleeve 6 is pressed with its cone-shaped support body 62 against the provided on the outer sleeve 5 inner cone.
- the molded into the support body guide grooves 64 each have a the groove flanks and the groove bottom forming wall and thus can simultaneously serve on their inside in Radylichtung side as a peripheral enclosure of the Ausschubfeder 7, which leads the Ausschubfeder 7 in the axial direction and buckling of the Ausschubfeder 7 prevented.
- the bearing pin 61 is, as in particular from the FIGS. 3 to 6 emerges, supported on the side bearing 2, 3 on the side part 1 and the visor cap 1 of the vertical awning, which in turn is part of a side bearing module 2, 3, 4, in the Fig. 16 - 19 is shown in detail and is connected to the side part 1 of the box.
- the bearing module 2, 3, 4 in this case has a fixed to the side part 1 bearing plate 3, on which an outer ring 31 of the slide bearing designed as a bearing 2, 3 is formed for the bearing pin 61.
- the bearing pin 61 is received in a bearing inner ring 2 of the sliding bearing 2, 3, which in turn is rotatably received in the bearing outer ring 31 of the bearing plate 3.
- the inner ring 2 is formed as a spherical cap. This means that its outer circumference facing the outer ring 31 has a spherical segment-shaped contour. Correspondingly, the inner circumference of the outer ring 31 of the bearing plate 3, which faces the inner ring 2, likewise has a spherical-segment-shaped contour, so that the inner ring 2 can swing out of the normal plane to the winding shaft axis, see FIG. 5 ,
- the winding shaft 10 is compressed or the support sleeve 6 pressed by pressure on the winding shaft 10 against the side part 1 in the formed by the two clamping bushes 5, 9 inner bushing 5, 9, so that the winding shaft 10 in the Kugelkalottenlager 2, 3rd Already taken bearing pin 61 can bring in its horizontal position, wherein that opposite end of the winding shaft so on the side part 11 passes over. Then then the on the winding shaft 10 and the Ausschubfeder 7 on the pressure applied to the support piece 6 and the side part 1 pressure - see FIG. 4 - By which the Ausschubfeder 7 relaxes and the support stub 6 ausschiebt to the outside and thus the winding shaft austeleskopiert in its operating position between the two side parts 1, 11.

Bei Gebäudeöffnungsverschattungsvorrichtung mit teleskopierbarer Wickelwelle stellt sich aber hauptsächlich nicht das Problem, die Wickelwelle zur Montage in der Werkstatt vollständig festzusetzen - wie in der
Gattungsgemäße Gebäudeöffnungsverschattungsvorrichtung weisen dazu einen federnd in der als Hohlwelle ausgebildeten Wickelwelle abgestützten und üblicherweise per Federkraft in die austeleskopierte Stellung vorgespannten Trägerstutzen auf, sowie eine Arretiereinrichtung zum Festsetzen des axialbeweglichen Trägerstutzens an der demgegenüber axialfesten Hohlwelle.Generic Gebäudeöffnungsverschattungsvorrichtung have for this purpose a resiliently supported in the form of a hollow shaft winding shaft and usually biased by spring force in the austeleskopierte position carrier nozzle, and a locking device for fixing the axially movable carrier nozzle on the other hand axially fixed hollow shaft.
Der Trägerstutzen, welcher einen Lagerzapfen zum Einhängen der Wickelwelle am Seitenteil des Rollladenkastens bildet, ist also über eine Feder in der Wickelwelle bzw. der Hohlwelle axialbeweglich abgestützt, so dass man die Wickelwelle bei der Montage mit dem federnden Ende (dem federnden Verlängerungskolben) schräggehalten an der dafür vorgesehenen Lagerung am Seitenteil ansetzen und mit der Wickelwelle auf den Trägerstutzen drücken kann, um dann das andere, starre Stirnende bei eingedrücktem Trägerstutzen nach oben zu verschwenken und an dem dafür vorgesehenen Lager am gegenüberliegenden Kasten-Seitenteil unter per Federkraft erfolgender Ausdehnung der Wickelwelle auf ihre ursprüngliche Ausdehnung in Ansatz zu bringen.The support piece, which forms a bearing pin for suspending the winding shaft on the side part of the shutter box, is thus supported axially movable by a spring in the winding shaft or the hollow shaft, so that the winding shaft during assembly with the resilient end (the resilient extension piston) at an angle the appropriate storage on the side panel and can press with the winding shaft on the support tube, then to pivot the other, rigid front end with depressed support piece up and at the designated camp on the opposite box side part under spring force extending expansion of the winding shaft to use their original extension.
Es sind schon verschiedene Möglichkeiten vorgeschlagen worden, mit denen der Trägerstutzen an der Wickelwelle bzw. der Hohlwelle gegen ein im Betrieb unerwünschtes axiales Eindrücken gesichert werden kann.There are already various possibilities have been proposed, with which the support piece can be secured to the winding shaft or the hollow shaft against an undesirable during operation axial impressions.
Ein Beispiel zeigt die europäische Patentschrift
Eine Wickelwelle mit einem federnden Ende zeigt auch die europäischen Patentanmeldung
Hiervon ausgehend ist es Aufgabe der vorliegenden Erfindung, eine gattungsgemäß mit einer als Hohlwelle ausgebildeten Wickelwelle und einem darin teleskopierbar aufgenommenen Trägerstutzen ausgestattete Gebäudeöffnungsverschattungsvorrichtung mit einer einfach bedienbaren und günstig zu fertigenden Sicherungseinrichtung gegen ein unerwünschtes Zusammendrücken der eingebauten Wickelwelle zu schaffen.On this basis, it is an object of the present invention to provide a genus with a trained as a hollow shaft winding shaft and a telescoping recorded therein carrier nozzle building opening shading device with an easy-to-use and inexpensive to manufacture safety device against unwanted compression of the built-in winding shaft.
Diese Aufgabe wird durch die Merkmale des Anspruchs 1 gelöst.This object is solved by the features of
Erfindungsgemäß weist die Sicherungseinrichtung zum Einen eine axial nach außen weisende, Anschlagsfläche am mit dem Trägerstutzen versehenen Stirnende der Hohlwelle auf. Zum Anderen einen am zugeordneten Seitenteil zur Hohlwelle hin vorspringenden Gegenanschlagszapfen mit einer der Anschlagsfläche zugewandten Gegenanschlagsfläche. Da die Anschlagsfläche mit der Hohlwelle mitdreht und die Gegenanschlagsfläche feststeht ist die Anschlagsfläche insbesondere ringförmig. Der Gegenanschlagszapfen ist dabei aus einer Sicherungs- bzw. Arretierstellung, in der er sich auf radialer Höhe des ringförmigen Anschlags befindet und ein Zusammendrücken der drehbar in Betriebsstellung befindlichen Wickelwelle (also ein Eindrücken des Trägerstutzens in die Wickelwelle hinein) verhindert oder zumindest begrenzt, entnehmbar am zugeordneten Seitenteil aufgenommen bzw. aus seiner Sicherungs- bzw. Arretierstellung heraus bewegbar.According to the invention, the securing device on the one hand has an axially outwardly pointing abutment surface on the front end of the hollow shaft provided with the support stub. On the other hand, on the associated side part of the hollow shaft towards projecting counter stop pin with one of Stop surface facing counter stop surface. Since the abutment surface rotates with the hollow shaft and the counterstop surface is fixed, the abutment surface is in particular annular. The Gegenanschlagszapfen is from a securing or locking position in which it is located at the radial height of the annular stop and compression of the rotating shaft in the operating position winding shaft (ie, a depression of the carrier nozzle in the winding shaft inside) prevented or at least limited, removable on associated side member added or movable out of its securing or locking position.
Die Sicherung gegen ein unerwünschtes Eindrücken des Trägerstutzens wird also indirekt durch ein Begrenzen einer in Axialrichtung zum Seitenteil hin möglichen Bewegung der starren Hohlwelle, in der der Trägerstutzen wiederum axialbeweglich aufgenommen ist, bewirkt, und nicht direkt durch ein Begrenzen der Bewegungsmöglichkeit des Trägerstutzens gegenüber dem Seitenteil bzw. der Blendkappe oder gegenüber der ihn aufnehmenden Hohlwelle. Trotzdem wird eine axiale Relativbewegung des Trägerstutzens gegenüber der Hohlwelle insoweit verhindert, dass sichergestellt ist, das der Trägerstutzen nicht soweit gegen das Lager einen das Lager aufnehmenden Lagerträger oder das Seitenteil gedrückt werden kann, dass die Wickelwelle als Ganzes weit genug einteleskopiert, um sich aus ihrem Sitz zu lösen.Securing against unwanted impressions of the carrier nozzle is thus indirectly by limiting an axial direction to the side portion of possible movement of the rigid hollow shaft, in which the carrier nozzle is in turn received axially movable causes, and not directly by limiting the possibility of movement of the carrier nozzle relative to the side part or the diaphragm cap or against the hollow shaft receiving it. Nevertheless, an axial relative movement of the carrier nozzle relative to the hollow shaft is prevented to the extent that it is ensured that the support piece not so far against the bearing a bearing receiving bearing bracket or the side panel can be pressed that the winding shaft as a whole far enough telescoped to get out of their To solve the seat.
Dadurch, dass der vom Monteur zu betätigende Teil der Sicherungseinrichtung nun am Seitenlagerteil der Gebäudeöffnungsverschattungsvorrichtung vorgesehen ist anstatt am Trägerstutzen, um diesen gegenüber der Hohlwelle festzusetzen, und dadurch, dass dieser bewegliche Teil der Sicherungseinrichtung auch lediglich in seine Sicherungsstellung gebracht oder aus dieser entfernt werden muss, kann die Sicherungseinrichtung insgesamt einfach und kostengünstig ausgebildet sein. Es genügt, an der Hohlwelle eine ringförmige Anschlagsfläche, beispielsweise an einem Ringflansch vorzusehen und am Seitenteil z.B. einen höhenverschiebbarer Riegel mit dem Gegenanschlagszapfen, der zu Montagezwecken entnommen werden kann oder bevorzugt im Sinne besserer Verliersicherheit an dem Seitenteil direkt oder an einem anderen, dort befestigten Bauteil, beispielsweise einer das Lager tragenden Lagerplatte geführt aufgenommen sein kann.The fact that the part of the securing device to be actuated by the fitter is now provided on the side bearing part of the building opening shading device instead of on the support piece to fix this against the hollow shaft, and in that this movable part of the securing device also only has to be brought into its securing position or removed from this , The safety device can be designed overall easy and inexpensive. It is sufficient to provide on the hollow shaft an annular abutment surface, for example on an annular flange and on the side part, for example, a höhenverschiebbarer bar with the counter stop pin, which can be removed for assembly purposes or preferably in the sense better Loss of security on the side part directly or at another, there fastened component, such as a bearing bearing bearing plate can be recorded out.
Weiterhin kann auch eine gute Zugänglichkeit des vom Monteur zu betätigenden Teils der Sicherungseinrichtung erreicht werden, weil im Bereich des Seitenteils zum Einen nach unten hin genügend Platz im Wickelwelleneinbauraum ist, um das mit dem Gegenanschlagszapfen versehenen Bauteil, also bevorzugt einen höhenverschiebbar am Seitenlagerteil aufgenommenen Sicherungsschieber, nach unten bis zur Unterseite des Einbauraums der Wickelwelle zu verlängern, und weil zum Anderen das Seitenlagerteil und damit der Sicherungsschieber mit dem Gegenanschlagszapfen nicht mit der Wickelwelle mitdreht.Furthermore, a good accessibility of the fitter to be actuated by the installer of the securing device can be achieved because in the region of the side part for a downwards enough space in the winding shaft installation space to the provided with the counter stop pin component, so preferably a vertically displaceable on the side bearing part recorded safety slide, extend down to the bottom of the installation space of the winding shaft, and because on the other hand, the side bearing part and thus the safety slide with the counter-stop pin does not rotate with the winding shaft.
Vorteilhaft ist die Länge der Hohlwelle dabei gegenüber dem axialen Abstand der Seitenteile natürlich so gewählt, dass zwischen der hohlwellenseitigen Anschlagsfläche und der Gegenanschlagsfläche ein Spiel besteht. Die Gegenanschlagsfläche des Gegenanschlagszapfens ist also auch in der Sicherungsstellung vorteilhaft etwas von der Anschlagsfläche an der Wickelwelle beabstandet, um ein Reiben der Wickelwelle an dem Gegenanschlagszapfen zu verhindern. Aufgrund von Windlasten oder dergleichen wird dies jedoch nicht immer zu verhindern sein. Diese auf die Wickelwelle im Betrieb wirkenden Querkräfte sind ja gerade der Grund dafür, dass eine Sicherungseinrichtung gegen ein unerwünschtes Eindrücken des Trägerstutzens in die Hohlwelle hinein vorgesehen ist. Ergänzend zu dem Abstand zwischen Anschlagsfläche und Gegenanschlagsfläche kann die die Gegenanschlagsfläche daher mit einem Material mit einem niedrigen Reibungskoefizienten versehen sein, beispielsweise Kunststoff.Of course, the length of the hollow shaft is of course chosen in such a way with respect to the axial spacing of the side parts that a clearance exists between the hollow shaft-side stop surface and the counter stop surface. The counter-stop surface of the counter-stop pin is therefore also in the securing position advantageously spaced slightly from the abutment surface on the winding shaft in order to prevent rubbing of the winding shaft on the counter-stop pin. However, due to wind loads or the like, this will not always be preventable. These transverse forces acting on the winding shaft during operation are precisely the reason why a safety device is provided against unwanted impressions of the carrier nozzle into the hollow shaft. In addition to the distance between stop surface and counter stop surface, the counter stop surface may therefore be provided with a material with a low coefficient of friction, for example plastic.
Anders ausgedrückt kann die Gegenanschlagsfläche an einem Bauteil vorgesehen sein, welches aus einem solchen Material besteht oder mit einem solchen Material beschichtet ist. Vorteilhaft besteht der den Gegenanschlagszapfen aufweisende Sicherungsschieber daher aus Kunststoff. Die Anschlagsfläche kann dagegen an einer stirnseitig auf die Hohlwelle aufgesetzten Hülse ausgebildet sein, welche dann einen stirnseitigen, axialen nach außen ragenden Ringflansch aufweist, an dem die ringförmige Anschlagsfläche ausgebildet ist. Die Hülse kann dabei vorteilhaft gleichzeitig die zur Aufnahme des Trägersstutzens nötige, in der Hohlwelle aufgenommene Innenhülse sein. Die Hülse besteht wegen der aufzunehmenden Lasten wie auch der Trägersstutzen bevorzugt aus einem metallischen Material wie Zinkdruckguss, könnte an der Anschlagsfläche aber ebenfalls mit Kunststoff beschichtet sein.In other words, the counter stop surface may be provided on a component which consists of such a material or is coated with such a material. Advantageously, the counter-locking pin having safety slide therefore made of plastic. On the other hand, the abutment surface may be formed on a sleeve which is mounted on the end face on the hollow shaft and which then has an end-side, axial, outwardly projecting annular flange on which the annular abutment surface is formed. The sleeve can advantageously be at the same time the necessary for receiving the support nozzle, recorded in the hollow shaft inner sleeve. The sleeve is due to the male loads as well as the support stub preferably made of a metallic material such as zinc die-casting, but could also be coated on the stop surface with plastic.
Weiterhin vorteilhaft ist es, wenn der Sicherungsschieber, an dem der Gegenanschlagszapfen ausgebildet ist, beispielsweise als von einem Basisabschnitt rechtwinklig abstehend angeformter Gegenanschlagszapfen, verliersicher an dem Seitenteil direkt oder an einem an dem Seitenteil befestigten Bauteil aufgenommen ist, und zwar verschiebbar zwischen der Sicherungsstellung und einer Freigabestellung, in der sich der Gegenanschlagszapfen radial außerhalb der ringförmigen Anschlagsfläche befindet, also beispielsweise oberhalb des an der Hohlwelle direkt oder an der Innenbuchse vorgesehenen Ringsflansches.It is also advantageous if the safety slide on which the counter-stop pin is formed, for example, as a counter-protruding pin projecting at right angles from a base portion, is captively received on the side part directly or on a component fastened to the side part, displaceable between the securing position and one Release position in which the counterstop pin is located radially outside the annular abutment surface, that is, for example, above the provided on the hollow shaft directly or on the inner sleeve ring flange.
Zur verschiebbaren Halterung des Sicherungsschiebers kann vorteilhaft eine Platte, beispielsweise eine ein Lager für einen Lagerzapfen des Trägerstutzens tragende Lagerplatte an dem Seitenteil befestigt sein, auf deren der Wickelwelle zugewandten Seite der Sicherungsschieber aufliegt, und welche von dem Sicherungsschieber hintergriffen wird. Zwischen der Platte und dem Seitenteil kann dann ein Schlitz sein, in den der Sicherungsschieber mit seinem die Platte hintergreifenden Abschnitt eingreifen kann. Der Sicherungsschieber ist dann vorteilhaft mit ausschließlichem Bewegungsfreiheitsgrad in Verschieberichtung zwischen seinen beiden Stellungen, der Freigabestellung der Sicherungsstellung am Seitenteil bzw. an der an dem Seitenteil befestigten Platte aufgenommen.For displaceable mounting of the safety slide can advantageously be a plate, for example, a bearing for a bearing journal bearing support bearing plate mounted on the side part, on which the winding shaft facing side of the safety slide rests, and which is engaged behind by the safety slide. Between the plate and the side part can then be a slot into which the safety slide can engage with its plate engaging behind the section. The safety slide is then advantageously taken up with exclusive freedom of movement in the direction of displacement between its two positions, the release position of the securing position on the side part or on the plate attached to the side panel.
Weiterhin vorteilhaft ist es dabei, wenn eine lösbare Rastverbindung des Sicherungsschiebers mit der mit dem Seitenteil verbundenen Platte, also beispielsweise der Lagerplatte vorgesehen ist, wobei die Rastverbindung zum lösbaren Rastbefestigen des Sicherungsschiebers in seiner Sicherungstellung dient und somit verhindert, dass sich der Sicherungsschieber ungewollt aus der die Wickelwelle gegen ein Zusammendrücken sichernden Sicherungsstellung löst. Weiterhin vorteilhaft kann die Rastverbindung auch so gestaltet sein, dass sie den Sicherungsschieber auch in seiner Freigabestellung an der Lagerplatte sichert.It is also advantageous if a releasable latching connection of the safety slide with the plate connected to the side panel, ie For example, the bearing plate is provided, wherein the locking connection is used for releasably latching fastening of the safety slide in its locking position and thus prevents the safety slide unintentionally triggers from the winding shaft against compression securing position. Further advantageously, the latching connection can also be designed so that it secures the safety slide in its release position on the bearing plate.
Die Rastverbindung kann dabei vorteilhaft einen von der wickelwellenabgewandten Rückseite der Platte, beispielsweise der Lagerplatte abstehenden Rastzapfen aufweisen, der von zwei Schenkeln einer die Platte, beispielsweise die Lagerplatte oberseitig hintergreifenden Rastgabel des Sicherungsschiebers umgriffen wird, welche beiden Schenkel somit gleichzeitig den die Platte, beispielsweise die Lagerplatte hintergreifenden Abschnitt des Sicherungsschiebers bilden können.The latching connection may advantageously have a projecting from the winding shaft back of the plate, for example, the bearing plate locking pin which is encompassed by two legs of a plate, for example, the bearing plate on the upper side engaging behind locking fork of the safety slide, which two legs thus simultaneously the plate, for example Can form bearing plate engaging behind section of the safety slide.
Die die Lagerplatte hintergreifenden Abschnitte bzw. der die Lagerplatte hintergreifende Abschnitt des Sicherungsschiebers können dabei von einem auf der wickelwellenzugewandten Seite der Lagerplatte ablaufenden Basisplatte des Sicherungsschiebers abgewinkelt sein.The bearing plate engaging behind sections or the bearing plate engaging behind portion of the safety slide can be angled from a running on the winding shaft side facing the bearing plate base plate of the safety slide.
Diese Basisplatte kann dabei als ringförmiger Verliersicherungsabschnitt ausgestaltet sein, welcher das am Seitenteil vorgesehene Lager und den darin mit seinem Lagerzapfen aufgenommenen Trägerstutzen radialseitig umgibt und somit sicherstellt, dass der Sicherungsschieber auch dann nicht abfällt, wenn sich der Hintergriff an der Lagerplatte lösen sollte.This base plate can be configured as an annular Verliersicherungsabschnitt, which surrounds the bearing provided on the side part bearing and the bearing pin therein radially on the radial side and thus ensures that the safety slide does not fall even if the rear handle should solve on the bearing plate.
Vorteilhaft springt der Gegenanschlagszapfen oberhalb des Lagers von der Basisplatte oder dem Verliersicherungsabschnitt des Sicherungsschiebers in Axialrichtung vor, weil es für einen Monteur besonders einfach ist, einen höhenverstellbaren Sicherungsschieber zu betätigen und weil dann der vom Verliersicherungsabschnitt nach unten abstehende Betätigungsabschnitt an dem Sicherungsschieber vorgesehen sein kann, der von dem Monteur lediglich nach oben oder unten verschoben werden muss, was den Zugriff auf den Sicherungsschiebers weiter erleichtert. Die Öffnung, durch die der Lagerzapfen und/oder das Lager am ringförmigen Verliersicherungsabschnitt des Sicherungsschiebers hindurchgeführt ist kann dann vorteilhaft ein mit vertikaler Achse ausgerichtetes Langloch sein.Advantageously, the counter stop pin protrudes above the bearing from the base plate or the Verliersicherungsabschnitt of the safety slide in the axial direction, because it is particularly easy for a mechanic to operate a height-adjustable safety slide and then because of the Verliersicherungsabschnitt downwardly projecting actuating portion may be provided on the safety slide, the by the fitter only after must be moved up or down, which further facilitates access to the safety slide. The opening through which the bearing pin and / or the bearing is passed on the annular Verliersicherungsabschnitt of the safety slide can then advantageously be aligned with a vertical axis slot.
Der nach unten ragende Betätigungsabschnitt ist vorteilhaft von einem Monteur greifbar, so dass zum Höhenverstellen des Sicherungsschiebers kein Werkzeug benötigt wird und weist daher unterseitig vorteilhaft eine zur Wickelwelle hin abgewinkelte Bedienungslasche auf.The downwardly projecting operating portion is advantageous from a fitter gripped, so that no height adjustment of the safety slide tool is needed and therefore has on the underside advantageous to the winding shaft angled towards operating tab.
Weiterhin vorteilhaft kann der nach unten ragende Betätigungsabschnitt eine unterseitige Sicherungslasche aufweisen, welche in die Gegenrichtung abgewinkelt ist, also von der Wickelwelle weg und zumindest in der Sicherungsstellung an einer zugeordneten, nach unten gewandten Halteschulter an der Lagerplatte anliegt, wodurch sich im Zusammenspiel mit der oberseitig an dem Sicherungsschieber vorgesehenen Rastgabel eine noch bessere Arretierung des Sicherungsschiebers in seiner Sicherungsstellung ergibt. Der Betätigungsabschnitt kann dann als Biegeschenkel ausgebildet sein, was sich bei einem aus Kunststoff bestehenden Sicherungsschieber nahezu von selbst ergibt, welcher mit seiner Unterseite soweit von der Lagerplatte wegbiegbar ist, dass die Sicherungslasche außer Anlage an der Halteschulter gelangt.Further advantageously, the downwardly projecting actuating portion having an underside securing tab, which is angled in the opposite direction, ie away from the winding shaft and at least in the securing position on an associated, downwardly facing retaining shoulder on the bearing plate, resulting in interaction with the upper side provided on the safety slide locking fork results in an even better locking of the safety slide in its securing position. The actuating portion may then be formed as a bending leg, which results in a safety slide made of plastic almost by itself, which is wegzubiegbar so far with its underside of the bearing plate that the locking tab out of engagement with the retaining shoulder.

Zunächst wird Bezug genommen auf die
Das federnde Achskappenmodul weist, wie
Der Trägerstutzen 6 bildet zusammen mit den beiden Spannbuchsen 5, 9 und der Ausschubfeder 7 ein Spannelement 5, 6, 7, 9, welches durch eine mit 8 bezeichnete Klemmbuchse geführt ist, bzw. die Klemmbuchse 8 durchgreift und über welches die Klemmbuchse 8 in der Wickelwelle 10 verklemmbar ist. Die durch die beiden Spannbuchsen 5, 9 gebildete Innenbuchse 5, 9 bildet zusammen mit der Klemmbuchse 8, durch die sie hindurchgeführt ist, eine Buchsenanordnung 5, 8, 9.The
Die äußere Spannbuchse 5 weist dabei, wie in
Dabei weist die äußere Spannbuchse 5 einen nach radial außen vorstehenden Anschlagsflansch 52 auf und die innere Spannbuchse 9 einen sich in Wickelwellenachsrichtung von innen nach außen konusförmig verjüngenden Außenumfangsabschnitt bzw. Keilabschnitt 92 (siehe
Die innenumfangsseitigen Oberflächen der Gegenkeilsegmente 83 verlaufen auf einer der Konusform des Keilabschnitts 92 der inneren Spannbuchse 9 entsprechenden Konuskontur und können sich aufgrund der durch Segmentzwischenräume 85 unterteilten Fächerstruktur aufspreizen, wenn die Verschraubung der beiden Klemmbuchsen 5, 9 angezogen wird und sich die beiden Klemmbuchsen dann aufeinander zubewegen und dadurch über den radial vorspringenden Anschlagsflanschring 52 an der äußeren Klemmbuchse 5 einerseits und den konusförmigen Keilabschnitt 92 an der inneren Spannbuchse 9 andererseits einen nach radial außen gerichteten Druck auf die Gegenkeilsegmente 83 der Klemmbuchse 8 ausüben.The inner peripheral side surfaces of the
Das Spannelement 5, 6, 7, 9 und die Klemmbuchse 8 bilden somit ein durch Anziehen oder Lösen der Verschraubung der beiden Spannbuchsen 5, 9 betätigbares Keilgetriebe, über welches sich die Klemmbuchse 8 gegen den Innenumfang der hohlen Wickelwelle 10 drücken lässt, wodurch sich das Achskappenmodul insgesamt in der Hohlwelle 10 verankern lässt.The clamping
Dabei wird über verschiedene Maßnahmen sichergestellt, dass bei einem Verdrehen der äußeren Spannbuchse 5 die innere Spannbuchse 9 drehfest gehalten wird, so dass sich die Verschraubung der beiden Spannbuchsen 5, 9 überhaupt erst betätigen lässt. Zum Einen ist der Keilwinkel an dem konischen Keilabschnitt 92 der inneren Spannbuchse 9 und an dem durch die Gegenkeilsegmente 83 gebildeten Gegenkeilabschnitt 82 der Klemmbuchse 8 recht klein gewählt, im dargestellten Beispiel ca. 10°, wobei sich die Keil- bzw. Gegenkeilabschnitte 82, 83 über eine relativ große axiale Länge erstrecken und nahezu um den gesamten Umfang herum. Dadurch wird ein nur nahezu selbsthemmender Reibschluss zwischen der inneren Spannbuchse 9 und der Klemmbuchse 8 erreicht. Darüber hinaus stehen, siehe
Wie
Die äußere, verdrehbare Spannhülse 5 wird dabei über den Trägerstutzen 6 betätigt, welcher in
An den Lagerzapfenabschnitt 61 schließt in Wickelwellenachsrichtung innen über einen ringförmigen, radialen Wandabschnitt 65 ein Trägerkörper 62 an, welcher einen sich nach axial innen konisch aufweitenden Außenumfang aufweist. Darin ist eine Mehrzahl über den Umfang verteilter, insgesamt konzentrisch zur Wickelwellenachse angeordneter und längs der Wickelwellenachse verlaufender Führungsnuten 75 nach radial innen eingeformt, der eine entsprechende Mehrzahl von innenumfangsseitig in Radialrichtung nach innen vorstehender Finnen 54 an der äußeren Klemmbuchse 5 zugeordnet ist, wobei sich die Finnen 54 entsprechend ebenfalls wickelwellenkoaxial erstrecken, siehe
Die äußere Spannbuchse 5 weist dabei entsprechend der Konusform des Trägerkörpers 64 innenumfangsseitig eine sich in Wickelwellenachsrichtung nach außen hin konisch verjüngende Innenumfangsoberfläche auf, von der die Finnen 54 vorstehen. Dadurch ergibt sich eine gute Selbstzentrierung des Trägerstutzens 6 in der äußeren Spannbuchse 5 und eine spielfreie Lagerung, wenn der Trägerstutzen 6 über die Ausschubfeder 7 in seine aus der Hohlwelle 10 ausgefahrene Betriebsstellung nach außen hin vorgespannt wird.The
Die innere Spannbuchse 9 weist ferner, siehe
Der Lagerzapfen 61 ist dabei, wie insbesondere aus den
Das Lagermodul 2, 3, 4 weist dabei eine an dem Seitenteil 1 befestigte Lagerplatte 3 auf, an der ein Außenring 31 des als Gleitlager ausgebildeten Lagers 2, 3 für den Lagerzapfen 61 ausgebildet ist. Der Lagerzapfen 61 ist dabei in einem Lagerinnenring 2 des Gleitlagers 2, 3 aufgenommen, der wiederum in dem Lageraußenring 31 der Lagerplatte 3 drehbar aufgenommen ist.The
Der Innenring 2 ist dabei als Kugelkalotte ausgebildet. Das heißt, dass sein dem Außenring 31 zugewandter Außenumfang eine kugelsegmentförmige Kontur aufweist. Entsprechend weist der dem Innenring 2 zugewandte Innenumfang des Außenrings 31 der Lagerplatte 3 ebenfalls eine kugelsegmentförmige Kontur auf, so dass sich der Innenring 2 aus der Normalebene zur Wickelwellenachse herausschwenken lässt, siehe
Dies ist im Hinblick auf die Montage der Wickelwelle 10 vorteilhaft, welche bei wie in

Um zu verhindern, dass die Wickelwelle 10 während des Betriebs unerwünscht zusammengedrückt wird und dadurch aus ihrer Lagerung an den beiden stirnseitigen Seitenteilen 1, 11 herausfällt, ist dabei eine Sicherungseinrichtung 4, 5 vorgesehen, die einerseits einen an dem Seitenlagermodul 2, 3, 4 vorgesehenen Sicherungsschieber 4 umfasst und andererseits eine axial nach außen weisende, ringförmige Anschlagsfläche am mit dem Trägerstutzen 6 versehenen Wellenende der Wickelwelle 10.In order to prevent that the winding
Die ringförmige Anschlagsfläche ist dabei an einem stirnseitigen, Ringflansch bzw. zylindischen Vorsprung oder Anschlagsring 51 an der äußeren Spannbuchse 5 vorgesehen, wobei die äußere Spannbuchse 5 als Teil des Achskappenmoduls fest in der Wickelwelle 10 verankert ist.The annular abutment surface is provided on an end face, annular flange or cylindrical projection or stop
Der Sicherungsschieber 4 ist dabei höhenverschiebbar an der Lagerplatte 3 aufgenommen und weist einen zur Wickelwelle 10 in Wickelwellenachsrichtung hin vorspringenden Gegenanschlagszapfen 41 mit einer der Anschlagsfläche zugewandten Gegenanschlagsfläche auf. In einer Sicherungsstellung, in der sich der Gegenanschlagszapfen 41 mit seiner Gegenanschlagsfläche auf radialer Höhe der ringförmigen Anschlagsfläche an der äußeren Spannbuchse 5 befindet, wird ein Zusammendrücken der drehbar in Betriebsstellung befindlichen Wickelwelle 10 bzw. ein Eindrücken des Trägerstutzens 6 in die Innenhülse 5, 9 hinein verhindert, siehe
Der Sicherungsschieber 4 ist dabei wie durch Pfeil in
Der Sicherungsschieber 4 hat dabei einen den Lageraußenring 31 ringförmig umgebenden Verliersicherungsabschnitt 42 mit einer in vertikaler Richtung etwas lang gezogenen Öffnung, durch die der Lageraußenring 31 ragt, so dass der Sicherungsschieber 4 zwischen seiner Sicherungsstellung und seiner Freigabestellung höhenverschiebbar ist. An den Verliersicherungsabschnitt 42 ist oberseitig der zur Wickelwelle hin vorstehende Gegenanschlagzapfen 41 angeformt und unterseitig ein vertikal nach unten geführter Betätigungsabschnitt 43. Der Betätigungsabschnitt 43 weist an seiner Unterseite eine im 90° Winkel in Wickelwellenachsrichtung nach innen hin vorspringende, horizontal verlaufende Bedienungslasche 45 auf, an der der Monteur den Sicherungsring 4 zwecks Höhenverstellung greifen kann.The
