Fig. 1 shows in section a portion of a bearing provided with a device in accordance with the invention and mounted on a shaft. ,. Fig. 2 is an enlarged view of a portion of the device of the present invention as shown in Fig. 1.
Fig. 1 visar ett Éarti av en cylindrisk axel 1 med en ansats 2. Ett enradigt dpårkullager 3 är anordnat på axeln 1 med en sidoyta av dess Lnnerlöpring under anliggning mot ansatsen 2 på axeln 1. E ring 4 är anordnad på axeln 1 och hàlles mot motsatta sidoytan av lagrets 3 innerlöpring. Denna ring 4 kvarhålles ii läge, t.ex. medelst en làsring 5 av konventionellt slag, anordnad. i ett periferiellt spår i axeln 1.Fig. 1 shows a view of a cylindrical shaft 1 with a shoulder 2. A single-row groove ball bearing 3 is arranged on the shaft 1 with a side surface of its inner running ring abutting the shoulder 2 on the shaft 1. A ring 4 is arranged on the shaft 1 and is held against the opposite side surface of the inner race of the bearing 3. This ring 4 is held in position, e.g. by means of a locking ring 5 of conventional type, arranged. in a peripheral groove in the shaft 1.
Kullagret 3 i de! illustrerade utföringsexemplet är försett med ringformade tätningslameller 6 anordnade på vardera sida av lagret och värdera, på konventionellt sätt, med dess ytterkant 7 fast|förankrad i ett spår anordnat i det inre av ytterlöpringen o h vilken vid sin innerkant har en inåt böjd fläns 8, som bi dar en cylindrisk yta belägen på ett kort avstånd från den cylindriska ytan 9 i lagrets innerring, och bildar därmed tiälsammans med denna en lång tätningsspalt.Coal stored 3 in them! The illustrated embodiment is provided with annular sealing lamellae 6 arranged on each side of the bearing and value, in a conventional manner, with its outer edge 7 fixedly anchored in a groove arranged in the interior of the outer race and which has an inwardly curved flange 8 forms a cylindrical surface located at a short distance from the cylindrical surface 9 in the inner ring of the bearing, and thus together with it forms a long sealing gap.
Lagret kan natur igtvis ha andra typer av tätningsorgan, som överbryggar ut_ met mellan de två löpringarna, där tåtningseffekteníförbättras på ett sått liknande det visade, och tätningslam llen, som illustrerats kan också vara utformad utan de inåt böjda flänsen 8.The bearing may, of course, have other types of sealing means which bridge the space between the two running rings, where the sealing effect is improved in a manner similar to that shown, and the sealing lamella illustrated may also be formed without the inwardly bent flange 8.
Som bättre fram år av Fig. 2, har ringen 4 en cylindrisk borrning, medan ess yttre mantelyta har ett första ytparti 10, som slutta i riktning mot lagerringen. Den yttre mantelytan pà ri gen har företrädesvis också ytterligare ett sluttande ytparti 11 anordnat på andra sidan i förhållande till den första sluttande ytpartiet 10 och vänt bort från lagret. De förïta och ytterligare sluttande ytpartierna 10,11 på ring n 4 år förenade av ett mjukt krökt 4| 10 15 20 25 30 35 513 035 3 övergångsparti 12, där ringen 4 har sin maximala ytter- diameter.As better shown in Fig. 2, the ring 4 has a cylindrical bore, while its outer shell surface has a first surface portion 10, which slopes in the direction of the bearing ring. The outer shell surface of the rig preferably also has a further sloping surface portion 11 arranged on the other side relative to the first sloping surface portion 10 and facing away from the bearing. The front and further sloping surface portions 10,11 on ring n 4 years joined by a softly curved 4 | 10 15 20 25 30 35 513 035 3 transition portion 12, where the ring 4 has its maximum outer diameter.
Det första sluttande ytpartiet 10 har på sin gavelsida, som i monterat läge är vänd mot lagerringen, ett ringformat urtaget parti 13, vars främsta uppgift är att tillåta lagret att röra sig axiellt, en sträcka motsvarande normalt axiellt lagerglapp, utan att riskera att tätningsorganet (tätnings- lamellen) kommer i kontakt med ringen 4.The first sloping surface portion 10 has on its end face, which in mounted position faces the bearing ring, an annular recessed portion 13, the main function of which is to allow the bearing to move axially, a distance corresponding to normal axial bearing clearance, without risking the sealing member ( the sealing lamella) comes into contact with the ring 4.
Som visas i Fig. 1 är ringen 4 placerad för att med en av dess sidoytor 14 anligga mot sidoytan på lagrets innerring, på avstånd från ansatsen 2 på axeln. En elastisk ring 15, såsom en O-ring av gummi är placerad (Fig. 1) mot det första sluttande ytpartiet 10, varvid storleken av den elastiska ringen 15 är sådan att den befinner sig under lätt spänning också i det läge som visas i Fig. 1, och därmed orsakar en lätt, inåt verkande axiell kraft på lamellen för att skydda den från att röra sig utåt från dess tätande position.As shown in Fig. 1, the ring 4 is positioned to abut with one of its side surfaces 14 against the side surface of the inner ring of the bearing, at a distance from the shoulder 2 on the shaft. An elastic ring 15, such as an O-ring of rubber, is placed (Fig. 1) against the first sloping surface portion 10, the size of the elastic ring 15 being such that it is under slight tension even in the position shown in Figs. 1, thereby causing a light, inwardly acting axial force on the lamella to protect it from moving outward from its sealing position.
Det andra sluttande ytpartiet 11 på ringen 4 underlättar monteringen av den elastiska ringen 15 i dess driftsposition såsom visas i Fig. 1. Den maximala diametern hos ringen finns vid mellanområdet 12, men med de två sluttande rampytorna 11 och 10 är det ändå ganska enkelt att applicera den elastiska ringen 15, vilken efter montering kommer att hålla ett lätt tryck mot den angränsande lamellen 6, och därmed säkerställa att tátningsfunktionen bibehålles på denna sida av lagret.The second sloping surface portion 11 of the ring 4 facilitates the mounting of the elastic ring 15 in its operating position as shown in Fig. 1. The maximum diameter of the ring is at the intermediate area 12, but with the two sloping ramp surfaces 11 and 10 it is still quite simple to apply the elastic ring 15, which after assembly will maintain a light pressure against the adjacent lamella 6, and thus ensure that the sealing function is maintained on this side of the bearing.
Uppfinningen är inte begränsad till exakt det utförande som visas i och beskrives i anslutning till ritningarna, utan modifikationer och varianter är möjliga inom ramen för de bifogade patentkraven. Fastän tätningsorganet har visats och beskrivits är det till exempel uppenbart, att anordningen enligt uppfinningen kan användas som en tätningslamell x _., ...L ._ ._ a* tflmfl|l.«-\--.... _.. _... ...__ ._ ..\_.........._.-._ . t' _..
