Description
Sikrinq mod forureninq af en abninq, afstandsstvkke oq fremqanqsmade til sikrinq mod forureninq af en abninqProtection against contamination of a contaminant, spacer and method of protection against contamination of a contaminant
Opfindelsen angar en sikring mod forurening af en abning i en udvendig overflade pê en langstrakt maskindel. Maskindelens overflade mê danne en lukket kurve omkring en laengdeakse heraf, saledes at et ubrudt bênd kan bringes til at omslutte maskindelen i et plan vinkelret pê laengdeaksen. I fodevare-, medicinal- og foderproduktionsanlaeg er der saerlige krav til sikring af hoj hygiejnisk standart. Det har vaeret foreslaet i WO2014075678 (A1) at anvende kugleformede prop-elementer, som isaettes kugleformede fordybninger i êbningen, men der er risiko for at prop-elementerne spules ud af fordybningerne, og derfor mangier denne kendte teknik de nodvendige godkendelser. Det er opfindelsens formal at tilvejebringe en sikring, som bade kan godkendes i henhold til 3A og EHEDG standarder og som er let at anvende og uden at det oger omkostningerne vaesentligt.The invention provides a protection against contamination of an opening in an outer surface of an elongated machine part. The surface of the machine part must form a closed curve about a longitudinal axis thereof, so that an unbroken belt can be caused to enclose the machine part in a plane perpendicular to the longitudinal axis. Food, pharmaceutical and feed production plants have special requirements for ensuring a high standard of hygiene. It has been proposed in WO2014075678 (A1) to use spherical plug elements which are inserted spherical recesses in the opening, but there is a risk that the plug elements are flushed out of the recesses and therefore this prior art lacks the necessary approvals. It is the object of the invention to provide a fuse that can be approved both in accordance with 3A and EHEDG standards and which is easy to use and without significantly increasing costs.
Dette er opnêet ved, at et fleksibelt rundgêende ubrudt bênd er tilvejebragt hen over êbning og mod den udvendige overflade hvorved bêndet enten i sig selv daekker êbningen eller holder en prop fast i êbningen eller er fremstillet ud i et stykke med en prop, som passer formsluttende ned i êbningen. Den langstrakte maskindel kan fx vaere cylinderformet med enten cirkulaert eller ikke cirkulaert tvaersnit pê tvaers af laengdeaksen, den kan fx godt fremstê som et firkant eller et oval-ror. Det rundtgêende ubrudte bênd skal sidde rundt om den langstrakte maskindel og tilvejebringe en pak-kraft hele vejen rundt om êbningen, og ikke mindst i materiale-overgangen mellem bênd-materialet og maskindelens materiale skal der vaere trykspaending, sêledes at fremmedlegemer ikke kan traenge ind her, og fastholdes mellem bêndet og maskindelen.This is achieved by providing a flexible circular unbroken band across the opening and toward the outer surface whereby the band either itself covers the opening or holds a plug in the opening or is made out of a piece with a plug that fits form-fitting down in the opening. The elongated machine part may, for example, be cylindrical with either circular or non-circular cross-section of the longitudinal axis, for example it may well appear as a square or an oval tube. The circumferential unbroken belt must sit around the elongated machine part and provide a packing force all the way around the opening, and not least in the material transition between the bonding material and the material of the machine part, there must be compression tension, so that foreign bodies cannot penetrate here. , and is held between the band and the machine part.
Til yderligere sikring af det rundgêende bênd er dette i henhold til krav 2 anbragt i et spor, som straekker sig rundt langs maskindelens overflade. Her foretraekkes det, at sporet folger en frembringer for maskindelen, som forlober pa tvaers af laengdeaksen, idet det herved bedre kan sikres, at der altid er tryk-spaendinger mellem sporets sidevaegge og det rundgêende bands anlaegsflader mod sidevaeggene.To further secure the circular band, this is according to claim 2 arranged in a groove extending around the surface of the machine part. Here, it is preferred that the groove follows a generator for the machine portion which extends across the longitudinal axis, thereby better ensuring that there are always compressive stresses between the sidewalls of the groove and the abutting surface of the circular band against the sidewalls.
Specielt foretraekkes det, som anfort i krav 3, at det rundtgêende band har en aksial udstraekning, en radial tykkelse samt en diameter, som er dimensionerede sêledes i forhold til maskindelen og êbningen, at der i en materialeovergang mellem bênd-materialet og den udvendige overflade af maskindelens materiale altid er trykspaendinger. Denne udformning sikrer bade at det rundtgêende bênd sidder godt beskyttet i sporet, sa det ikke let slês ud af position, og samtidig at der vil kunne etableres en naesten jaevn og ubrudt overgang mellem bênd og maskindel sê der ikke opstêr spraekker eller indhak, hvor smuds kan ophobes.In particular, as stated in claim 3, it is preferred that the circumferential band has an axial extension, a radial thickness and a diameter dimensioned so as to be relative to the machine part and the aperture that in a material transition between the bonding material and the outer surface. of material of the machine part is always compressive stresses. This design ensures both that the circular band is well protected in the groove, so that it is not easily slid out of position, and at the same time that an almost smooth and uninterrupted transition between the band and the machine part can be said that no cracks or notches occur where dirt can accumulate.
Som anfort i krav 4, foretraekkes det, at sporet i det mindste er lige sê bredt i aksialretningen, som diameteren af den êbning sporet passerer hen over. Samtidig skal sporet have en ensartet dybde. Hermed sikres, at det rundtgêende bênd har en anlaegsflade i bunden af sporet hele vejen rundt langs êbningens ovre rand. Yderligere gor den ensartede dybde af sporet, at bêndet ogsê kan laves med ensartet godstykkelse i radialretningen, sê det kan saettes pê i en vilkêrlig rotation i forhold til maskindelens udvendige overflade og i forhold til hullerne, og alligevel altid daekke alle huiler effektivt af.As stated in claim 4, it is preferred that the groove is at least as wide in the axial direction as the diameter of the opening groove passes. At the same time, the track must have a uniform depth. This ensures that the circumferential band has a contact surface at the bottom of the groove all the way around the upper edge of the opening. Further, the uniform depth of the groove also allows the tape to be made with uniform thickness in the radial direction, say it can be applied in any rotation to the outside surface of the machine part and to the holes, and yet always cover all the cries effectively.
Som anfort i krav 5 foretraekkes det yderligere, at sporet dannes hen over êbningen med centrum for êbningen centreret i forhold til sporets udstraekning i aksialretningen. Sê sikres det, at bêndet har en anlaegsflade hele vejen rundt om êbningen i bunden af sporet, og skaevheder, hvor dele af bêndet fx glider ned i êbningen undgês.As stated in claim 5, it is further preferred that the groove is formed over the opening with the center of the opening centered relative to the extension of the groove in the axial direction. It is then ensured that the belt has a contact surface all the way around the opening at the bottom of the groove, and distortions where, for example, parts of the belt slip into the opening are avoided.
Desuden angar opfindelsen et afstandsstykke, der har to ender og omfatter en befaestelsesdel mod en maskine eller andet udstyr i den ene ende og en fod indrettet til kontakttryk mod en fast part i den anden ende, hvor afstanden mellem befaestelsesdelen og foden indstilles med en kraftoverforende mekanisme omfattende en udvendig cylinderformet del. Afstandsstykker af denne art er velkendte og benaevnes oftest ’’maskinfodder”, idet foden typisk er indrettet til at laegge an mod en plan flade sa som et gulv. Det er velkendt at forsoge at lave den afstandsregulerende mekanisme, sêledes at den opfylder hoje krav til hygiejne, fx ved at sikre at der ikke udefra er adgang til gevind eller andre spraekker, hvori bakteriefyldt materiale kan ophobes. Til sikring af abninger sa som gennemgêende gevindhuller i en udvendig cylindrisk kappedel af en sédan maskinfod foreslês det ifolge opfindelsen, at anvende et rundtgêende band som anfort ovenfor. En sédan sikring udvider anvendelsesmulighederne for netop denne type maskinfodder eller afstandsstykker, som nu vil kunne godkendes til anvendelse i laegemiddelindustrien, fodevareproduktion og produktion af dyrefodder.Furthermore, the invention relates to a spacer having two ends and comprising a fastener part against a machine or other equipment at one end and a foot arranged for contact pressure against a fixed part at the other end, where the distance between the fastening part and the foot is adjusted by a force transmitting mechanism. comprising an outer cylindrical portion. Spacers of this kind are well known and are most often referred to as '' machine feet '', the foot typically being adapted to touch a flat surface such as a floor. It is well-known to attempt to make the distance-controlling mechanism, such that it meets high hygiene requirements, for example by ensuring that no external threads or other cracks are available in which bacteria-filled material can accumulate. In order to secure openings such as through threaded holes in an outer cylindrical sheath portion of such a machine foot, it is proposed according to the invention to use a circular band as indicated above. Such a fuse extends the scope for just this type of machine feed or spacers, which can now be approved for use in the pharmaceutical industry, food production and animal feed production.
Som anfort i krav 7 har afstandsstykket et gevindhuld i den cylinderformede ydre maskindel, og i gevindhullet er der monteret en pinolskrue, sêledes at den cylinderformede maskindel kan sikres mod u-onskede bevaegelser béde rotationsmaessigt og i aksialretningen.As stated in claim 7, the spacer has a threaded hole in the cylindrical outer machine part and a threaded screw is mounted in the threaded hole, so that the cylindrical machine part can be secured against undesired movements both in rotation and in the axial direction.
Som anfort i krav 8 foretraekkes det, at det rundgêende bênd er af en relativ eftergivelig gummi-elastisk type, som har en praedefineret hêrdhed pê omkring 60 pts og en relativ lav traekstyrke pê ikke mindre end 4 Mpa. Med disse parametre kan man sikre et rundtêende bênd, som er meget fleksibelt og let lader sig montere eller afmontere fra det cylinderformede maskinelement og ogsê ved forekomsten af et spor rundt langs overfladen heraf, bliver det let at fê bêndet til at glide ned i sporet nêr det skal monteres. I en alternativ udformning af afstandsstykket er bêndet lavet af et materiale, som ikke taler afmontering efter den forste montage. Herved bliver det muligt altid at sikre at der kommer et nyt bênd pê ved aendringer, og ved forsog pa aendringer af afstandsstykket efter montage, vil der vaere en synlig marker af at et indgreb har vaeret foretaget, i det mindste indtil et nyt band kommer pê plads pa afstandsstykket.As stated in claim 8, it is preferred that the circular band be of a relatively resilient rubber elastic type having a predefined hardness of about 60 pts and a relatively low tensile strength of not less than 4 MPa. With these parameters one can ensure a circular belt which is very flexible and easily removable or detachable from the cylindrical machine element and also by the presence of a groove around the surface thereof, it becomes easy to get the belt to slide down the track near it must be fitted. In an alternative design of the spacer, the ribbon is made of a material that does not speak disassembly after the first assembly. In this way, it is always possible to ensure that a new tape comes on when changes are made, and when attempting to change the spacer after mounting, there will be a visible marker that an intervention has been made, at least until a new band comes on space on the spacer.
Opfindelsen angêr tillige en fremgangsmêde, til sikring mod forurening af en êbning i en udvendig overflade af en cylinderformet maskindel. Fremgangsmêden er saeregen ved at, et fleksibelt ubrudt bênd monteres omkring maskindelen og enten holder en prop fast i êbningen, er sammenhaengende med en prop som sidder i êbningen eller daekker êbningen helt, hvorved der etableres kraftsluitende anlaeg mellem maskindelens overflade og bêndet. Det kraftsluttende anlaeg mellem maskindelen og det rundtêende bênd sikrer mod at der optraeder hulrum eller spraekker mellem bêndets anlaegsflader og overfladen af maskindelen. Anvendes fx et fleksibelt bêndmateriale sê som Silicon Rubber 60 Shore A, Compound S6002F er det simpelt at dimensionere det rundtgêende bênd, sêledes at det ved anlaeg mod den cylinderformede ydre overflade af maskindelen altid er strakt ud med en procentvis forlaengelse, der ikke overstiger den ultimative forlaengelse, som for dette materiale anfores til >150% i henhold til testmetode D412 og til gengaeld er i det mindste forlaenget 3%, fortrinsvist mindst 4 til 6% ud over spaendingsfri neutraltilstand.The invention also relates to a method for preventing contamination of an opening in an outer surface of a cylindrical machine part. The method is particular in that a flexible unbroken belt is mounted around the machine part and either holds a plug in the opening, is connected to a plug which sits in the opening or completely covers the opening, thereby establishing a power-sealing system between the surface of the machine part and the belt. The force-sealing abutment between the machine part and the circumferential belt ensures that no cavities or cracks occur between the abutment surfaces of the belt and the surface of the machine part. For example, if a flexible band material is used, such as Silicon Rubber 60 Shore A, Compound S6002F, it is simple to size the circumferential band, so that when abutting the cylindrical outer surface of the machine part it is always extended with a percentage extension that does not exceed the ultimate Extension which for this material is quoted at> 150% according to test method D412 and in return is at least extended 3%, preferably at least 4 to 6% in addition to the stress-free neutral state.
Opfindelsen skal herefter naermere forklares under henvisning til tegningerne, pê hvilke:The invention will now be explained in more detail with reference to the drawings, in which:

Det bemaerkes, at i forskellige udforelsesformer for opfindelsen har forskelligt udseende emner samme henvisningstal i det omfang de udforer i det vaesentlige samme funktion i forbindelse med opfindelsen. I Fig. 5 ses et eksempel pê en sikring mod forurening af en abning 12 i henhold til kendt teknik. Her henviser 2 til en cylindrisk maskindel. I maskindelens udvendige overflade er der êbninger 12 i form af skruehuller. Til sikring mod forurening af hullerne med fx bakterieholdige substanser er der heri indsat kugleformede propper 6. Propperne er indrettede sê de lige netop lader sig presse ind i kugleformede hulrum, som er etablerede yderst mod den cylindriske maskindels 2 overflade og med en êbning mod overfladen, som er noget mindre end det kugleformede hulrums storste diameter. De kugleformede propper 6 lader sig tjerne med hêndkraft. Imidlertid har det vist sig, at disse propper anses for at vaere i risiko for at blive enten slêet ud eller spulet ud af deres kugleformede hulrum under saedvanlig brug, fx i fodevareproduktion, medicinalproduktion eller ved andre former for produktion hvor bakteriel forurening skal holdes under kontrol. En sédan prop, som utilsigtet er blevet tjernet fra sit hulrum indebaere fiere sikkerhedsmaessige udfordringer: dels efterlades hulrummet og abningen 12 ubeskyttet over for bakteriefyldte substanser, som kan saette sig fast her, og dels er selve den kugleformede prop 6 et sikkerhedsmaessigt problem, fordi den vil kunne optraede som fremmedlegeme i fedevare, foder eller medicin.It is to be noted that in different embodiments of the invention, different appearance items have the same reference numerals to the extent that they perform substantially the same function in connection with the invention. In FIG. 5 shows an example of a fuse against contamination of an aperture 12 according to the prior art. Here, 2 refers to a cylindrical machine part. In the outer surface of the machine part there are openings 12 in the form of screw holes. Spherical plugs are inserted herein to prevent contamination of the holes with, for example, bacteria-containing substances 6. The plugs are arranged to just be pressed into spherical cavities which are established extremely against the surface of the cylindrical machine part 2 and with an opening towards the surface, which is somewhat smaller than the largest diameter of the spherical cavity. The spherical plugs 6 can be harnessed with force. However, it has been found that these plugs are considered to be at risk of being either ejected or flushed out of their spherical cavities during normal use, for example, in food production, pharmaceutical production or in other forms of production where bacterial contamination is to be controlled. . Such a plug, which has been accidentally ejected from its cavity, poses several safety challenges: firstly, the cavity and aperture 12 are left unprotected against bacteria-filled substances that may become stuck here, and partly the spherical plug 6 is a safety issue. may act as a foreign body in food, feed or medicine.
Pa fig. 1 er vist en sikring mod forurening af en êbning 12 i henhold til opfindelsen. I den udvendig overflade 1 pa en cylindrisk maskindel 2 er vist et fleksibelt rundgêende ubrudt band 3, som er tilvejebragt hen over en êbning 12. I det viste eksempel pa opfindelsen er maskindelen en cirkelrund cylinder, men ikke cirkulaere cylindre eller maskindele som blot er langstrakte og har en laengdeakse er ogsê mêl for opfindelsen, idet det blot kraeves, at maskindelen har en ydre overflade, som kan omsluttes af et ubrudt bênd. Hvis et sédan band er monterbar pa en langstrakt maskindels ydre overflade, vil bêndet kunne tildaekke og dermed beskytte êbninger i maskindelens overflade. Abningen 12 vender ud mod den udvendige dels overflade 1 og i det viste eksempel daekker bêndet 3 i sig selv êbningen 12. Men bandet kan ogsê sidde hen over en prop, af den type, som er vist i Fig. 5 og her holde proppen 6 fast i abningen. I en yderligere udforelsesform (ikke vist), er bêndet 3 fremstillet ud i et stykke med en prop, som passer formsluttende ned i êbningen 12, sêledes at bêndet 3 igen kan sikrer proppens forbliven i êbningen 12. Ved de tre naevnte mêder at indrette opfindelsen pê, vil der altid komme et meget synligt tegn pê fejl sêfremt det ubrudte bênd 3 er 1]ernet, isaer hvis bêndet er udformet med en tydelig farve-kontrast i forhold til maskindelens udvendige overflade. Saedvanligvis er den cylindriske maskindel 2 fremstillet i rustfrit stél af en passende kvalitet i forhold til hvor kemisk aggressivt miljeet er, og det er relativt let at lade det ubrudte bênd 3 fremstille i en klar kontrastfarve hertil, sê som blê, gul eller red. Herved kan det med et enkelt blik konstateres, om alle huiler i en cylindrisk maskindel er ordentligt beskyttede, ogsê dem, som mêtte ligge pê bagsiden af maskindelen i forhold til en beskuer, idet tilstedevaerelse af det ubrudte bênd vil vaere indikation af at hullerne er beskyttede, og manglende tilstedevaerelse af bêndet vil indikere manglende beskyttelse.In FIG. 1, there is shown a protection against contamination of an opening 12 according to the invention. In the outer surface 1 of a cylindrical machine part 2 is shown a flexible circular unbroken band 3 which is provided over an opening 12. In the illustrated example of the invention the machine part is a circular cylinder, but not circular cylinders or machine parts which are merely elongated. and having a longitudinal axis is also an object of the invention, merely requiring that the machine part has an outer surface which can be enclosed by an unbroken belt. If such a band is mountable on the outer surface of an elongated machine part, the belt will be able to cover and thus protect openings in the surface of the machine part. The opening 12 faces the surface 1 of the outer part and in the example shown, the band 3 itself covers the opening 12. But the band can also sit over a plug, of the type shown in FIG. 5 and here the plug 6 holds in the opening. In a further embodiment (not shown), the band 3 is made in one piece with a plug which fits form-fittingly into the opening 12, such that the band 3 can again ensure the plug's stay in the opening 12. In the three aforementioned ways of arranging the invention On, there will always be a very visible sign of error if the unbroken belt 3 is 1], especially if the belt is designed with a clear color contrast with the outside surface of the machine part. Usually, the cylindrical machine part 2 is made of stainless steel of a suitable quality in relation to how chemically aggressive the environment is, and it is relatively easy to allow the unbroken band 3 to be produced in a clear contrasting color, say as blue, yellow or red. Hereby, it can be seen at a glance whether all the mounts in a cylindrical machine part are properly protected, as well as those which might be on the back of the machine part relative to a viewer, since the presence of the unbroken belt will be an indication that the holes are protected. , and the absence of the bandage will indicate a lack of protection.
Som det ses i fig. 1 og 2 har maskindelen 2 et rundtgaende spor 4 i sin udvendige cylinderformede overflade 1, og sporet er anbragt netop sê det krydser hen over êbningen 12. Her sidder bêndet 3 nede i sporet 4, og som det ses i Fig. 1, vil der vaere en naesten ubrudt overgang mellem bêndets udvendige overfalde 5 og maskindelens udvendige overflade 1. Herved sikres bêndet mod at blive forskubbet langs den udvendige overflade 1 og risikoen for at bandet skal lide skade ved tilfaeldige anslag mod bevaegelige genstande holdes ogsê lav.As seen in FIG. 1 and 2, the machine part 2 has a circumferential groove 4 in its outer cylindrical surface 1, and the groove is positioned just as it crosses over the opening 12. Here, the band 3 sits down in the groove 4, and as seen in FIG. 1, there will be an almost uninterrupted transition between the outer surface of the belt 5 and the outer surface of the machine part 1, thereby protecting the belt from being displaced along the outer surface 1 and the risk of the band suffering damage from accidental impact on moving objects is also kept low.
Den udvendige overflade 1 kan tilhore enhver maskindel, som har êbninger der skal beskyttes, og i det viste eksempel i figurerne 1 og 2 er cylinderformen cirkulaer, men ikke-cirkulaere cylindriske maskindele samt koniske elementer kunne ogsa komme pê tale, fx firkant- eller oval-ror med radiale abninger eller konus-overflade med radiale êbninger vil kunne beskyttes pa den her anviste méde, sê der ikke kommer fremmelegemer ind i êbningerne. I eksemplet i Fig. 1 er den cirkulaere cylinderformede maskindel 2 en udvendig del af en sêkaldt maskinfod eller afstandsstykke 10, hvorved den ene ende 9 af maskinfoden 10 sidder monteret i en maskine (ikke vist) og den modsatte ende 8 omfatter en fod 7 eller holder, som danner understotning mod vaeg, loft, gulv eller et ophaengsbeslag for maskinen, nêr maskinfoden er i brug. Det betyder, at det ubrudte bênd ikke kan fjernes fra maskinfoden 10, nêr den forst er i brug, men det vil kunne forskubbes langs den udvendige cylindriske overflade nêr êbningen 12 skal vaere tilgaengelig. Det kunne fx vaere ved justering af skruen 11, som er placeret i et indvendigt gevind 13 i êbningen 12.The outer surface 1 may belong to any machine part having openings to be protected, and in the example shown in Figures 1 and 2, the cylinder shape is circular, but non-circular cylindrical machine parts as well as tapered elements could also be present, e.g. square or oval -Roters with radial openings or cone surface with radial openings can be protected in the manner described here, saying that no foreign bodies enter the openings. In the example of FIG. 1, the circular cylindrical machine part 2 is an outer part of a so-called machine foot or spacer 10, whereby one end 9 of the machine foot 10 is mounted in a machine (not shown) and the opposite end 8 comprises a foot 7 or support forming against a wall, ceiling, floor or a suspension bracket for the machine when the machine foot is in use. This means that the unbroken belt cannot be removed from the machine foot 10 when it is first in use, but it can be displaced along the outer cylindrical surface when the opening 12 is available. It could be, for example, by adjusting the screw 11 which is located in an internal thread 13 in the opening 12.
Det bemaerkes at det rundtgêende ubrudte bênd 3, har en aksial udstrsekning L, en radial tykkelse T samt en indvendig diameter D, og disse skal vaere dimensionerede sêledes i forhold til hinanden, at der i en materialeovergang 14 mellem band-materialet og den udvendige maskindels materiale altid er trykspaendinger. Trykspaendingerne ervigtige, fordi de sikrer mod at fremmedlegemer traenger ind mellem de to materialer. Hvis bandet blot sidder udvendigt pa maskindelen 2 uden at der heri er tilvejebragt et spor, er det vigtigste mal for bêndet dets indvendige diameter, og her vil kravet vaere at bandets indvendige omkreds i det mindste ikke overstiger den udvendige omkreds af maskindelen 2. Hvis bandet er cirkulaert cylindrisk i upavirket tilstand, vil der vaere en simpel geometrisk sammenhaeng mellem bandets indre diameter og omkredsen langs dets indad vendende overflade. Bêndet 3 vil typisk vaere fremstillet af et fleksibelt gummielastisk materiale, og vil i praksis altid kunne stobes som et cirkulaert cylindrisk legeme, ogsa selv om maskindelen 2 har en ikke-cirkulaer frembringer vinkelret pa sin laengdeakse, eller fx har en konisk udvendig overflade.It is noted that the circumferential unbroken band 3 has an axial extension L, a radial thickness T and an inner diameter D, and these must be dimensioned relative to each other that in a material transition 14 between the band material and the outer machine part. material is always compressive. The compressive stresses are important because they ensure that foreign bodies penetrate between the two materials. If the band simply sits externally on the machine part 2 without providing a groove therein, the most important measure of the band is its inner diameter, and here the requirement would be that the inner circumference of the band does not at least exceed the outer circumference of the machine part 2. If the band If it is circularly cylindrical in its unaffected state, there will be a simple geometric connection between the inner diameter of the belt and the circumference along its inwardly facing surface. The band 3 will typically be made of a flexible rubber elastic material and will in practice always be cast as a circular cylindrical body, even if the machine part 2 has a non-circular perpendicular to its longitudinal axis or, for example, has a conical exterior surface.
Skal bandet 3 sidde i et spor som vist i fig. 1, kan L, T og D mêlene antages at vaere de nominelle mal for bandet 3, nêr det ikke sidder omkring en cylinderformet maskindel 2, og her vil et nominelt volumen Vband for bandet kunne beregnes. Pa samme vis vil der fra eksemplet i Fig. 2 kunne beregnes et nominelt volumen Vsp0r for sporet 4, og her vil kravet vaere, at Vband er en passende procentdel storre end Vsp0r. Procentdelen vil typisk ligge i omrêdet fra 1% til 15% fortrinsvist 5%. Samtidig mê det sikres, at L, T og D for henholdsvis band 3 og spor 4 ikke afviger vaesentligt fra hinanden, sêledes at bandets overstorrelse i forhold til sporet er ligeligt fordelt pa L og T og altid sédan at laengden af den indre omkreds af bandet altid er mindre end laengden af den indre omkreds i sporet.Should the band 3 sit in a groove as shown in FIG. 1, the L, T and D measures can be assumed to be the nominal dimensions for the band 3 when it is not around a cylindrical machine part 2, and here a nominal volume Vband for the band can be calculated. Similarly, from the example of FIG. 2, a nominal volume Vspor for the track 4 could be calculated, and here the requirement would be that Vband is an appropriate percentage larger than Vspor. The percentage will typically be in the range of 1% to 15%, preferably 5%. At the same time, it must be ensured that L, T and D for band 3 and track 4 do not differ substantially from each other, respectively, so that the band's size relative to the track is evenly distributed between L and T and always such that the length of the inner circumference of the band always less than the length of the inner circumference of the groove.
Det foretraekkes at sporet har en udstraekning i aksial retning langs den udvendige materialeoverflade 1 og har samme dybde i hele sin udstraekning idet sporets 4 udstraekning i aksialretningen ikke er mindre end êbningens 12 diameter. Her er sa antaget at êbningen er cirkulaer, hvilket vil vaere det mest almindeligt forekommende. Ved denne relation mellem det rundtgêende spor 4 og êbningen 12 sikres det, at der hele vejen rundt langs randen af êbningen 12 er en anlaegsflade 15 parallelt med det cylindriske maskindels overflade 1. Denne konstruktion er med til at sikre at bêndet 3 altid ligger fladt til mod randen af abningen og forsegler denne. Som det yderligere ses i fig. 1 er sporet 4 centreret i forhold til êbningens udstraekning langs maskindelens centerakse. Herved sikres det, at det stykke sporet overstiger abningens 12 udstraekning i aksialretningen fordeles ligeligt ved hver side af abningen 12, og der vil da komme et ligeligt fordelt tryk mellem bandet og randen af êbningen, som definerer anlaegsfladen 15. Béde det i Fig. 2 og det i Fig. 4 viste eksempel pê opfindelsen omfatter et afstandsstykke 10, der har to ender 8,9 hvor den ene ende 9 omfatter et faeste mod en maskine (ikke vist) eller andet udstyr. Et sédan faeste kan fx udgores af en gevindstub, som kan skrues ind i et gevindhul i maskinen, eller det kan omfatte en prespasning, eller en svejsetab, sê afstandsstykket kan svejses fast til maskinen. Andre velkendte former for faester mellem afstandsstykket og maskinen kan anvendes. I den anden ende 8 er der hensigtsmaessig tilvejebragt en fod 7 indrettet til kontakttryk mod en fast part. Her kan foden 7 vaere indrettet pê mange forskellige mêder, béde som griber til montage omkring ror, eller som svejsestub, der svejses fast til en bjaelke eller anden understottende del. Centralt for afstandsstykkets funktion er, at afstanden mellem befaestelsesdelen 9 og foden 7 er indstillelig via en kraftoverforende mekanisme og omfatter en udvendig cylinderformet del 2 med en overflade 1. Et sédan afstandsstykke 10 er i Fig. 2 og Fig. 4 vist med en traditionel fod 7 i den ene ende, hvor foden 7 omfatter et gummielement 17 med en anlaegsflade 18 indrettet til at laegge an mod fx et gulv i et vaerksted eller produktionslokale. Gummielementet 17 er sa fx vulkaniseret ind i en metalkabe 19. Mellem gummielementet 17 og et kraftoverforende ben 20 kan der evt. vaere tilvejebragt et fleksibelt led, sa som et kugleled 21, hvilket tillader det kraftoverforende ben 20 at vinkelstilles i forhold til foden 7. Saedvanligvis er en central del af metalkaben 19 og undersiden af det kraftoverforende ben 20 udformet som de to i forhold til hinanden frit roterbare dele af et kugleled 21.It is preferred that the groove has an axial extension along the outer material surface 1 and has the same depth throughout its extension, the extension of the groove 4 in the axial direction being not less than the diameter of the opening 12. It is assumed here that the opening is circular, which will be the most common. This relationship between the circumferential groove 4 and the opening 12 ensures that all along the edge of the opening 12 there is a abutment surface 15 parallel to the surface of the cylindrical machine part 1. This construction helps to ensure that the band 3 is always flat to towards the edge of the aperture and seal it. As further seen in FIG. 1, the groove 4 is centered relative to the extension of the opening along the center axis of the machine part. This ensures that the piece of groove exceeds the extent of the aperture 12 in the axial direction is distributed equally on each side of the aperture 12, and then there will be an evenly distributed pressure between the band and the rim of the aperture which defines the abutment surface 15. Both of these in FIG. 2 and that of FIG. 4 of the invention comprises a spacer 10 having two ends 8,9, one end 9 of which comprises a fastener against a machine (not shown) or other equipment. Such a fastening can be made, for example, by a threaded rod which can be screwed into a threaded hole in the machine, or it may comprise a press fit, or a welding loss, say the spacer can be welded to the machine. Other well-known forms of fasteners between the spacer and the machine can be used. At the other end 8 there is conveniently provided a foot 7 arranged for contact pressure against a fixed part. Here, the foot 7 can be arranged in many different ways, either as a gripper for mounting around rudders, or as a welding rod which is welded to a beam or other supporting part. Central to the function of the spacer is that the distance between the attachment portion 9 and the foot 7 is adjustable via a force transmitting mechanism and comprises an outer cylindrical portion 2 with a surface 1. Such spacer 10 is shown in FIG. 2 and FIG. 4 shown with a traditional foot 7 at one end, the foot 7 comprising a rubber element 17 with a contact surface 18 arranged to touch, for example, a floor in a workshop or production room. For example, the rubber member 17 is vulcanized into a metal casing 19. Between the rubber member 17 and a force-transmitting leg 20, it is possible to a flexible joint, such as a ball joint 21, is provided, which allows the force-transmitting leg 20 to be angled relative to the foot 7. Usually, a central portion of the metal cap 19 and the underside of the power-transmitting leg 20 are formed as the two relative to each other freely. rotatable parts of a ball joint 21.
Mellem det kraftoverforende ben 20 og faestet mod en maskine 9 er der indrettet en mekanisme til justering af laengden af afstandsstykket 10, som ikke er vist i detaljer i figuren. Det kan vaere et cylinder-stempelpar eller det kan vaere en spindelmekanisme med et udvendigt gevind horende fx til det kraftoverforende ben 20, og et indvendigt hertil modsvarende gevind i et cylindrisk ror. Ved at rotere roret i forhold til benet vil de to elementer foretage en teleskop-bevaegelse i forhold til hinanden, og idet det cylindriske ror er forbundet til enden 8 med faeste mod maskinen, kan afstanden mellem fod 7 og maskine justeres.A mechanism for adjusting the length of the spacer 10, which is not shown in detail in the figure, is arranged between the power-transmitting leg 20 and fixed to a machine 9. It may be a cylinder piston pair or it may be a spindle mechanism with an external thread belonging, for example, to the power-transmitting leg 20, and an internally corresponding thread in a cylindrical tube. By rotating the rudder relative to the leg, the two elements will make a telescopic motion relative to each other, and as the cylindrical rudder is connected to the end 8 with attachment to the machine, the distance between the foot 7 and the machine can be adjusted.
Til sikring mod utilsigtet rotation eller forskydning af den cylindriske maskindel 2 i forhold til det kraftoverforende ben 20 er der i den cylindriske maskindel 2 isat skruer 11 i hertil indrettede abninger 12 med gevind 13 som tidligere forklaret.In order to prevent accidental rotation or displacement of the cylindrical machine part 2 with respect to the power-transmitting leg 20, screws 11 are inserted in the cylindrical machine part 2 in openings 12 with threads 13 as previously explained.
Den cylindriske maskindel kan have andre funktioner end de her viste og beskrevne, fx kan det vaere en kontra-motrik, som sa pê tilsvarende vis skal blokkeres med en pinolskrue 11.The cylindrical machine part may have functions other than those shown and described here, for example it may be a counter-nut, which must then be similarly blocked with a pin screw 11.
Det foretraekkes ifolge opfindelsen at det rundgêende bênd er fremstillet i silikone og har en praedefineret hêrdhed i Shore A pa mellem 55 og 70 pts, fortrinsvist en hardhed pa 60 pts samt traekstyrke pê ikke mindre end 4 Mpa. Hermed fês sikkerhed for dels at bêndet kan monteres relativt let omkring en maskinfods udvendige cylindriske maskindel 2, og dels at bêndet 3 kan laegge an med den fornodne kraft mod dette elements metaloverflade og forsegle herimod. I en alternativ udforelsesform er det rundgêende band fremstillet i en plasttype, der har en sédan hêrdhed og elastisk udvidelse, at afmontering fra maskindelen vil medfore destruktion af bêndet. Hermed vil bêndet kunne fungere som anbruds-indikator, der viser om der pê et tidligere tidspunkt har vaeret êbnet for adgang til de forseglede êbninger 12. I Fig. 3 og Fig. 4 er der vist en lidt anden udformning af en maskinfod 10, hvor det ubrudte bênd 3 sidder pê en konusformet forlaengelse 22 af cylindriske maskindel 2I. Denne forlaengelse 22 er placeret naermest foden 7, men kunne vaere anbragt i den modsatte ende af maskindelen 2. Som det ses i fig. 3, er sporet dannet som en neddrejning med aksielle endevaegge 23, som er vinkelrette pê konusfladens retlinede frembringere 25, og med en bund 24, som er parallelle med konusfladens retlinede frembringere 25. Et ubrudt bênd passende til dette spor, mê have parallelt forlobende konusformet indre og ydre overflade, og en ens-tyk godstykkelse herimellem. I det viste eksempel er êbningen 12 ikke centreret i forhold til hverken sporets ovre rand eller sporet bund. Men det er naturligvis muligt at centrere êbningen 12 efter det rundgêende spors bund 24, sêledes at den overste rand af êbningen 12 har samme afstand til det rundgêende spors 4 aksielle endevaegge 23, sê den parallelle anlaegsflade 15 her altid har et mindstemêl hele vejen rundt langs êbningen 12. Som det er antydet i figuren, er bêndets ydre konusformede overflade svagt hvaelvet, nêr bêndet sidder i sporet, og gêr dermed lidt ud over maskindelens retlinede frembringere 25. Dette kommer af at bêndets volumen er lidt storre end sporets volumen, for som beskrevet at sikre trykspaendinger mellem bêndets og sporets respektive anlaegsflader mod hinanden.It is preferred in accordance with the invention that the circular band is made of silicone and has a predefined hardness in Shore A of between 55 and 70 pts, preferably a hardness of 60 pts and a tensile strength of not less than 4 MPa. This ensures that the band can be mounted relatively easily around the outer cylindrical machine part 2 of a machine foot and partly that the band 3 can apply with the necessary force against the metal surface of the element and seal against it. In an alternative embodiment, the circular band is made of a plastic type having such a hardness and elastic extension that removal from the machine part will result in destruction of the belt. In this way, the tape will be able to act as a break indicator showing whether an earlier opening has been opened for access to the sealed openings 12. In Figs. 3 and FIG. 4, a slightly different configuration of a machine foot 10 is shown, in which the unbroken belt 3 sits on a cone-shaped extension 22 of cylindrical machine part 2I. This extension 22 is located closest to the foot 7, but could be located at the opposite end of the machine part 2. As seen in FIG. 3, the groove is formed as a pivot with axial end walls 23 perpendicular to the cone face's rectilinear generators 25, and with a base 24 parallel to the cone face's rectilinear generators 25. An unbroken band suitable for this groove must have a cone-shaped parallel extending inner and outer surface, and a uniform thickness between them. In the example shown, the opening 12 is not centered relative to neither the upper edge of the groove nor the groove bottom. But, of course, it is possible to center the aperture 12 after the bottom 24 of the circular groove, such that the upper edge of the aperture 12 is the same distance from the axial end walls 23 of the circular groove 4, the parallel abutment surface 15 here always has a minimum diameter all the way around. Opening 12. As indicated in the figure, the outer cone-shaped surface of the belt is slightly arched when the belt sits in the groove, thus slightly exceeding the rectilinear generators of the machine part 25. This is because the volume of the belt is slightly larger than the volume of the track, as described to ensure compressive stresses between the respective abutment surfaces of the band and the groove.
Sporene i de ovenfor anviste eksempler er med parallelle sider, som forlober vinkelrette pê maskindelens overflade og har en plan bund, som ligeledes er parallel med maskindelens overflade i et skaeringsplan gennem maskindelens laengdeakse. Men andre typer af spor er mulige, fx med v-formede vaegge og afrundet bund. Eller sporet kan udformes som en halvcirkel i et skaeringsplan gennem maskindelens akse. I overgangen fra et spors side og maskindelens overflade kan der fx i hver af sporets sider vaere tilvejebragt en skarp indadrettet flange, som det gummi-elastiske bêndmateriale presses ned under for at blive korrekt monteret. Afmontering af bêndet bliver herved vanskelig, og vil muligvis kraeve brug af vaerktoj, til gengaeld kan en sédan konstruktion giveforbedre hygiejnisk sikring. I figurerne 6A - 6D vises en serie af fotografier, der illustrerer forskellige stadier i pêsaetningen af et band: - 6A bandet 3 ligger ovenpa foden og er ikke monteret, - 6B bandet 3 er blevet pafort glidemiddel, sê som vand og eventuelt saebe, og med fingerkraft er bandet lagt i sporet ved den vaek fra operatoren vendende side af maskinfoden, og bliver nu skubbet og/eller trukket ud, sê det kan falde ned i sporet, - 6C bêndet skubbes det sidste stykke ned i sporet ved den mod operatoren vendende side af maskinfoden, - 6D bêndet masseres langs sin ydre overflade til det sidder jaevnt fordelt rundt langs den cylinderformede maskindels overflade, sê der ikke er spraekker mellem bêndet og sporet. I figurerne 7A og 7B er vist billeder af hvordan bêndet 3 afmonteres: - 7A her forer operatoren med et pincetgreb og et vist tryk med fingrene om bêndet 3 fingrene i samme retning, fx vaek fra operatoren, hvorved bêndets overflade pê to modstêende sider udsaettes for en forskydningskraft i retning vaek fra operat0ren. Dette medf0rer at bêndet i omradet naermest operat0ren straekkes og i omradet vendende vaek fra operat0ren vil der akkumuleres ekstra band-materiale, - 7B her ses hvordan operat0ren f0rer fingerspidser eller negle ind under den akkumulerede ekstra band-materiale, som har medfort at bêndet i dette omrade sidder tilstraekkeligt lest, til at dette er muligt. Nar forst fingrene er inde under bêndet, lader det sig relativt let straekke, sê det kan leftes ud af sporet hele vejen rundt. I det viste eksempel har bêndet en udstraekning i den cylinderformede maskindels aksialretning pê 9,0 mm, hvor sporet har en udstraekning i aksialretningen pê 7,5 mm. Herved sikres det, at bêndet nêr det sidder i sporet, altid fylder dette helt op, og laegger an med trykkraft mod siderne af sporet.The grooves in the above examples are with parallel sides extending perpendicular to the surface of the machine part and having a flat bottom which is also parallel to the surface of the machine part in a plane of cutting through the longitudinal axis of the machine part. But other types of tracks are possible, for example with v-shaped walls and rounded bottom. Or the groove can be formed as a semicircle in a plane of intersection through the axis of the machine part. For example, in the transition from the side of a groove to the surface of the machine part, a sharp inwardly directed flange may be provided, under which the rubber-elastic band material is pressed down to be properly mounted. Removing the strap will thus be difficult, and may require the use of tools, however, such a construction can improve hygienic protection. Figures 6A - 6D show a series of photographs illustrating various stages in the fitting of a band: - 6A band 3 is on top of the foot and is not mounted, - 6B band 3 has become a lubricant, say as water and possibly soap, and with finger force, the band is placed in the groove at the away from the operator side of the machine foot, and is now pushed and / or pulled out, says it can fall into the track, - the 6C tape is pushed the last piece down the track by the facing towards the operator side of the machine foot, - The 6D band is massaged along its outer surface until it is evenly distributed along the surface of the cylindrical machine part, saying there are no cracks between the band and the groove. Figures 7A and 7B show pictures of how to remove the band 3: - 7A here, the operator with a forceps grip and a certain pressure with the fingers about the band 3 fingers in the same direction, eg away from the operator, thereby exposing the surface of the band to two opposite sides. a shear force away from the operator. This means that the tape in the area closest to the operator is stretched and in the area facing away from the operator will accumulate extra band material, - 7B here is how the operator places fingertips or nails under the accumulated extra band material which has contributed to the band in this area. area is sufficiently read for this to be possible. Once the fingers are under the strap, it can be stretched relatively easily, saying it can be left out of the groove all the way around. In the example shown, the strip has an extension in the axial direction of the cylindrical machine part of 9.0 mm, the groove having an extension in the axial direction of 7.5 mm. This ensures that the band when it is in the groove always fills it up completely and applies with compressive force to the sides of the groove.
