DK 157347 BDK 157347 B
Opfindelsen angâr et leje til et pâ en aksel anbragt· jord-bearbejdningsværktoj, især en harvetallerken, og som er tætnet ved hjælp af en tætning mellem dets yderring og inderring, og yderringen er bevægelig i forhold til det legeme, hvori 5 den er anbragt.The invention relates to a bearing for a shaft mounted on a soil tillage tool, in particular a harrow plate, which is sealed by means of a seal between its outer ring and inner ring, and the outer ring is movable relative to the body in which it is placed.
Et sâdant leje er kendt fra U.S. patent nr. 2.733.648, hvor der mellem yder- og inderringen findes en ringformet tætning, som glider pâ inderringen. Ved relativ bevægelse mellem yder-10 ringen og det denne optagende legeme, der i det foreliggende tilfælde er lejestotten for den drejelige aksel, der bærer jordbearbejdningsværktojet, kan der herved traenge snavs ind i lejet mellem stotten og yderringen.Such a rental is known from U.S. No. 2,733,648, wherein there is an annular seal between the outer and inner rings, which slides on the inner ring. By relative movement between the outer ring and this accommodating body, which in the present case is the bearing support for the pivot shaft carrying the tillage tool, dirt can penetrate into the bearing between the support and the outer ring.
15 Endvidere kendes fra U.S. patent nr. 3.311.429 et leje af den indledningsvis nævnte art, hvor det yderringen optagende legeme radiait strækker sig i hovedsagen frem til inderringen for afskærmning af lejet. Denne konstruktion har imidlertid den ulempe, at graden af lejets svingning eller bevægelse 20 begrænses. Desuden vil, selv om afskærmningen afskærmer, for det meste snavs eller de fleste skadelige materialer, stadig en del af disse trænge ind i rummet mellem afskærmningen og tætningen og herfra trænge ind i grænsefladen mellem stotten og yderringen, hvorved der vil opstâ en beskadigelse af de 25 her op til hinanden liggende flader.Furthermore, from U.S. Pat. Patent No. 3,311,429 is a bearing of the kind mentioned in the preamble, wherein the outer ring receiving body radially extends substantially to the inner ring for shielding the bearing. However, this construction has the disadvantage that the degree of bearing vibration or movement 20 is limited. Furthermore, although the shielding shields, for the most part, dirt or most of the harmful materials, some of these will still enter the space between the shielding and the seal and from here penetrate the interface between the support and the outer ring, thereby causing damage to the 25 adjacent surfaces.
Formâlet med den foreliggende opfindelse er under bibeholdel-se af tilstrækkelig bevægelighed mellem yderringen og det legeme, hvori dette er anbragt, at anvise en mere fordelagtig 30 lejekonstruktion, som tilnærmelsesvis fuldstændig forhindrer indtrængning af skadeligt materiale i lejet.The object of the present invention is, while maintaining sufficient movement between the outer ring and the body in which it is disposed, to provide a more advantageous bearing structure which substantially completely prevents the ingress of harmful material into the bearing.
Til opnâelse af dette formâl er lejet ifolge opfindelsen ejen-dommeligt ved, at tætningen strækker sig frem til det yder-35 ringen optagende legeme og ved relativbevægelser kan glide pâ dette. Herved opnâs, at der ikke kan trænge snavs ind i omrâdet mellem yderringen og det denne optagende legeme.In order to achieve this purpose, the bearing according to the invention is characterized in that the seal extends to the body receiving the outer ring and can slide on it by relative movements. Hereby it is obtained that no dirt can enter the area between the outer ring and this absorbing body.

If0lge opfindelsen kan tætningen hâve en fleksibel tætnings-læbe, som ligger an mod legemet, og endvidere en mod inder-ringen anliggende tætningslæbe. Tætningslaeberne er hensigts-mæssigt udformet ud i et stykke.According to the invention, the seal can have a flexible sealing lip which abuts the body, and furthermore a sealing lip adjacent to the inner ring. The sealing lips are suitably formed in one piece.

Desuden kan ifolge opfindelsen tætningen være stabiliseret med en perforeret afstivningskerne.Furthermore, according to the invention the seal can be stabilized with a perforated stiffening core.
Endvidere kan ifolge opfindelsen tætningslaeberne bestâ af jg forskellige materialer.Furthermore, according to the invention, the sealing lips may consist of various materials.
Ved et leje til en tallerkenharve med ved siden af lejet an-bragte afstandsstykker kan ifolge opfindelsen tætningen strække sig frem til afstandsstykket.By means of a bearing for a disc harrow with spacers placed next to the bed, the seal can extend to the spacer according to the invention.

Endelig kan der ifolge opfindelsen i yderringen være tildannet en radial smorekanal. Herved kan sâvel det omrâde, hvor der optræder en relativ bevægelse mellem legemet og yderringen, som omrâdet mellem lejeringene smores.Finally, according to the invention in the outer ring, a radial lubrication channel may be formed. In this way, the area where there is a relative movement between the body and the outer ring, as well as the area between the bearing rings, can be lubricated.

Legemet 16 har ligeledes en bærearm 32, som med skruer 34 er forbundet med redskabsrammen 10, og som med skruebolte 40 er forbundet med udstansede flangedele 36 og 38.In FIG. 1 is shown part of a typical plate harrow having a 10 tool frame 10 and plates 12, soin is mounted on a shaft 14. The shaft is supported by a body 16 which is formed in a bearing support. The tool frame further carries a wiper rudder 18 by means of U-braces 20,22 and lugs 24. Adjustable wiper plates 26 are pivotally mounted on the rudder 18 by means of spring-loaded pulling arms 15 and are pulled by pull springs 30 towards one surface of each plate. . The body 16 also has a support arm 32, which with screws 34 is connected to the tool frame 10 and which with screw bolts 40 is connected to punched flange parts 36 and 38.
20 I fig. 2 er vist et snit gennem akselen 14, et leje 46 og tilstodende afstandsstykker 42 og 44. Det ses endvidere, at lejet er anbragt mellem flangedelene 36 og 38, og at der pâ akselen 14 er anbragt en inderring 48 og en yderring 50, idet 25 der mellem disse findes kugler eller rullelegemer 52. Flange delene 36 og 38 har en indvendig sfærisk overflade 56, hvorpâ yderringen er anbragt, og den ydre overflade 54 pâ yderringen er tilsvarende udformet sfærisk.In FIG. 2, there is shown a section through the shaft 14, a bearing 46 and adjacent spacers 42 and 44. It is further seen that the bearing is disposed between the flange portions 36 and 38 and that on the shaft 14 is an inner ring 48 and an outer ring 50, 25 there are spheres or roller bodies 52 between them. The flange portions 36 and 38 have an inner spherical surface 56 on which the outer ring is disposed and the outer surface 54 of the outer ring is similarly spherically formed.
30 Afstandsstykkerne 42 og 44 er stobte og er anbragt sâledes pâ hver side af lejet, at de ligger an mod siderne af inder-ringen 48. Diameteren af den flade af hvert afstandsstykke, som ligger an mod inderringen 48, er storre end diameteren af inderringens yderflade.The spacers 42 and 44 are molded and disposed on each side of the bearing so as to abut the sides of the inner ring 48. The diameter of the surface of each spacer abutting the inner ring 48 is greater than the diameter of the inner ring 48. outer surface.

fleksible tætningslæber 60, soin strækker sig radiait·indad, og en fleksibel tætningslæbe 62, der er rettet udad. Tætnings-læberne 60 og 62 er udformede ud i ét stykke og bæres af en afstivningskerne 64, sont atter er anbragt pâ en ringformet 5 skàlformet holder 66. Denne bæres af yderringen 50. Tætningens tætningslæber 60 strækker sig radiait indad og glider pâ den ydre rundtgâende overflade 68 af inderringen 48, nâr denne lober rundt sammen med akselen 14 under arbejdet i marken. Tætningslæben 62 har et tykkere tværsnit end de andre tæt-10 ningslæber, og den glider pâ den indvendige overflade 70 af en del 72 af hver flangedel 36 og 38, idet denne overflade aksialt strækker sig forbi og ned over yderkanten af yderringen 50.flexible sealing lips 60, radially extending inwardly, and a flexible sealing lip 62 directed outward. The sealing lips 60 and 62 are integrally formed and supported by a stiffening core 64, which is again mounted on an annular holder 66. This is supported by the outer ring 50. The sealing lips 60 of the seal extend radially inwardly and slide on the outer circumferential surface. surface 68 of the inner ring 48 as it loops around with the shaft 14 while working in the field. The sealing lip 62 has a thicker cross-section than the other sealing lips, and it slides on the inner surface 70 of a portion 72 of each flange portion 36 and 38 as this surface extends axially past and down the outer edge of the outer ring 50.
15 Afstivningskernen 64 har radiait forlobende perforeringer 74 og danner stotte for tætningslæben 62, sâledes at der kon-tinuerligt er kontakt mellem den indvendige overflade 70 af delen 72 pâ flangedelen under arbejdet. De radiale perforeringer 74 i afstivningskernen 64 bevirker, at tætningslæberne 20 60 og 62 kan fremstilles ud i ét stykke af samme materiale, hvorved der opnâs en stor elasticitet og styrke.The stiffener core 64 has radially extending perforations 74 and provides support for the seal lip 62 so that there is continuous contact between the inner surface 70 of the portion 72 of the flange portion during operation. The radial perforations 74 in the stiffener core 64 cause the sealing lips 20 60 and 62 to be made in one piece of the same material, thereby providing a high elasticity and strength.
I fig. 2 er vist en smorenippel 76 til pâfyldning af smare-middel til lejet. Denne smarenippel 76 er anbragt pâ flange-25 delen 36. Flangedelene 36 og 38 er udformet sâledes, at der er dannet et hulrum eller smaremiddelréservoir 78 ud for srnare-nippelen 76. Endvidere er der i yderringen udformet en aksialt forlabende smarekanal 80. Det nævnte hulrum 78 sikres ved hjælp af en tynd pakningsring 82 mod spild af smaremiddel, 30 nâr dette indpresses i smarenippelen 76, idet pakningsringen er anbragt mellem flangedelene 36 og 38.In FIG. 2, there is shown a lubricating nipple 76 for loading lubricant to the bed. This lubrication nipple 76 is disposed on the flange portion 36. The flange portions 36 and 38 are formed such that a cavity or lubricant reservoir 78 is formed next to the nipple nipple 76. Furthermore, an axially extending lubrication channel 80 is formed in the outer ring. cavity 78 is secured by means of a thin gasket ring 82 against wastage of lubricant 30 when pressed into the grease nipple 76, the gasket ring being disposed between the flange portions 36 and 38.
I fig. 4 og 5 er vist lignende tætninger, som dog har andre afstivningskerner 64 henholdsvis 84. I fig. 5 er tætningslæben 35 62 udformet sâledes, at den fleksibelt kan glide pâ den ud- vendige overflade 86 af et naboafstandsstykke 42, hvorved hindres indtrængning af snavs i et omrâde 88, som ligger op 5In FIG. 4 and 5 are shown similar seals, however, having other stiffening cores 64 and 84, respectively. 5, the sealing lip 35 62 is configured so that it can slide flexibly on the exterior surface 86 of a neighboring spacer 42, thereby preventing the ingress of dirt into an area 88 which is up 5

til den indad forl0bende tætningslæbe 60. Afstivningskernen 64 i fig. 4 er udformet saledes, at den fungerer som ekstra stette for den udvendige overflade 90 af tætningslæben 62, saledes at der fâs en bedre kontakt mellem denne tætningslæbe 5 og den indvendige overflade 70 af delen 72 pâ flangen.to the inwardly extending sealing lip 60. The stiffener core 64 of FIG. 4 is designed so that it acts as extra support for the outer surface 90 of the sealing lip 62, so that better contact between this sealing lip 5 and the inner surface 70 of the portion 72 of the flange is provided.
Fig. 6 og 7 viser indbyrdes adskilte tætningslæber henholds-vis 92 og 94, som er forbundet med en fælles skâlformet holder 66 henholdsvis 96, hvorved der kan anvendes forskellige tæt-10 ningsmaterialer til fremstilling af tætningslæberne 92 og 94.FIG. 6 and 7 show spaced-apart sealing lips 92 and 94, respectively, which are connected to a common shell-shaped holder 66 and 96, respectively, whereby different sealing materials can be used to make the sealing lips 92 and 94.
De i fig..7 og 8 viste skâlformede holdere 96 og 98 er udformet saledes, at de har en ombojet overflade, der er forbundet 15 med yderringen 50. Den skâlformede holder 98 i fig. 8 tjener som eneste afstivningskerne til afstivning af tætningen, og endvidere tjener den til at forbinde tætningslæben med yderringen 50.The shell-shaped holders 96 and 98 shown in FIGS. 7 and 8 are designed so as to have a curved surface connected to the outer ring 50. The shell-shaped holder 98 in FIG. 8 serves as the sole stiffener core for stiffening the seal, and further serves to connect the sealing lip to the outer ring 50.
20 De i fig. 3, 4, 5 og 7 viste skâlformede holdere 66 og 96 er hver udformet med en vertikalt forlobende vægdel 100, der ligger i afstand fra den yderste spids 102 pâ den nærmeste indadrettede tætningslæbe 60. Denne vægdel 100 sikrer, at de indadrettede tætningslæber 60 ved monteringen af yderringen 25 50 og tætningen 58 pâ inderringen 48 ikke drejer sig og med deres spidser kommer til at pege i retning mod rullelegemerne 52.20 In FIG. The shell-shaped holders 66 and 96 shown in Figures 3, 4, 5 are each formed with a vertically extending wall portion 100 spaced from the outermost tip 102 of the nearest inwardly sealing lip 60. This wall portion 100 ensures that the inwardly sealing lips 60 at the mounting of the outer ring 25 50 and the seal 58 of the inner ring 48 do not rotate and with their tips will point in the direction towards the rollers 52.
Pâ en sædvanlig tallerkenharve anvendes normalt to eller tre 3° legemer 16 til at bære akselen 14 og de tilhorende taller- kener. Pâ grund af de vertikale og horisontale kræfter, som virker pâ tallerkeherne 12 under arbejdet, og som derved ogsâ overfores til legemerne 16, kan det ofte være vanskeligt at fâ akselen 14 til at flugte najagtigt med aile legemerne 16.In a conventional disc harrow, two or three 3 ° bodies 16 are usually used to carry the shaft 14 and the associated plates. Due to the vertical and horizontal forces acting on the discs 12 during work, and which are thereby also transferred to the bodies 16, it can often be difficult to cause the shaft 14 to align accurately with all the bodies 16.
35 Lejet 46 mâ derfor udformes sâledes, at det er selvjusterende og kan kompensere for en oprindelig manglende opretning og for dynamiske forskydninger under arbejdet.35 The bearing 46 must therefore be designed so that it is self-adjusting and can compensate for an initial failure to align and for dynamic shifts during work.

Nâr en tallerkenharve trækkes over marken, og tallerkenerne 12 lober rundt, sâ overfores de vertikale og horisontale kræf-ter gennem tallerkenerne .12 til akselen 14 og de dele, der bærer denne. Disse kræfter fores videre til redskabsrammen 2 10 over hvert af legemerne 16, hvorved der til ved siden af hinanden liggende legemer 16 overfores fluktuerende horisontale og vertikale kræfter. Som folge heraf mâ lejerne for akselen 14 være i stand til at optage noget slor i forhold til akselen og ligeledes oscillerende bevægelser af legemerne 10 16 og flangerne 36 og 38 i forhold til yderringen 50. Det er af denne grund, at der mâ findes et smoremiddelreservoir 78 til smoring af overfladerne 56 og 54 mellem flangedelene 36 og 38 og yderringen 50.When a disc harrow is pulled over the field and the discs 12 run around, the vertical and horizontal forces are transmitted through the discs .12 to the shaft 14 and the parts carrying it. These forces are further applied to the tool frame 20 over each of the bodies 16, thereby imparting fluctuating horizontal and vertical forces to adjacent bodies 16. As a result, the bearings for the shaft 14 must be able to absorb some slack relative to the shaft and likewise oscillating movements of the bodies 10 16 and the flanges 36 and 38 relative to the outer ring 50. It is for this reason that a lubricant reservoir 78 for lubricating surfaces 56 and 54 between flange portions 36 and 38 and outer ring 50.
15 Nâr tallerkenerne 12, akselen 14 og inderringen 48 lober rundt under arbejdet, sâ vil vand, snavs, sand og andre skadelige stoffer ramme legemerne 16 og afstandsstykkerne 42 og 44.15 As the plates 12, shaft 14 and inner ring 48 run around during work, water, dirt, sand and other harmful substances will hit the bodies 16 and spacers 42 and 44.
For at forhindre, at disse skadelige materialer trænger ind i rummet mellem de indvendige overflader 56 pâ flangedelene 20 36 og de udvendige overflader 54 pâ yderringen 50 og ind i hulrummet eller smoremiddelreservoiret 78 mellem yderringen 50 og flangedelen 36, er tætningen 58, som det fremgâr af fig. 2 og 3, udformet sâledes, at den ligger an mod den indvendige overflade 70 af flangedelen 36 og kan glide pâ denne.In order to prevent these harmful materials from entering the space between the inner surfaces 56 of the flange portions 20 36 and the outer surfaces 54 of the outer ring 50 and into the cavity or lubricant reservoir 78 between the outer ring 50 and the flange portion 36, the seal 58 is as shown. of FIG. 2 and 3, formed so as to abut the inner surface 70 of the flange portion 36 and may slide thereon.
25 Nâr akselen 14, inderringen 48 og afstandsstykkerne 42 og 44 lober rundt, sâ glider tætningslæben 62 pâ den udvendige omkreds 86 af afstandsstykket 42 og lukker tæt mod dette, sâledes at indtrængning af skadelige materialer i rummet 88 hindres. Pâ grund af denne tætningslæbe kan der anvendes flange-30 dele 36 og 38, som sammen med afstandsstykkerne 42 og 44 danner hulrum 104, som tillader de sideværts oscillerende bevægelser af flangedelene 36 og 38 pâ yderringen 50.25 As the shaft 14, the inner ring 48 and the spacers 42 and 44 loop around, the sealing lip 62 slides on the outer circumference 86 of the spacer 42 and closes tightly against it, thus preventing the penetration of harmful materials into the space 88. Because of this sealing lip, flange members 36 and 38 can be used which together with spacers 42 and 44 form cavities 104 which allow the laterally oscillating movements of flange members 36 and 38 on outer ring 50.
En i tværsnit i hovedsagen V-formet rundtgâende rille 106 er anbragt langs omkredsen af afstandsstykkerne 42 og 44 i omrâdet ved legemet 16, hvorved trâd og lignende materiale kan vikle sig rundt om denne i stedet for at komme ind i hulrummet 104A generally circular V-shaped circumferential groove 106 is disposed along the circumference of the spacers 42 and 44 in the region of the body 16, whereby threads and similar material may wrap around it instead of entering the cavity 104.
