Abstract

A two-row angular-contact ball bearing comprises a notched inner race (3) arranged to extend into the region of the ball row (5) and a cage (4) having an inwardly-extending protrusion (8) adapted to snap-fit into the notch (7). The cage (4) or a part thereof is constructed as a prong-type cage in the region of a second inner race (2) which does not have a notch, the cage having sections (9') capable of clawing the balls in the said other row (5) of balls. The second inner race (2) may be provided at its ends facing the notched inner race (3) with a shoulder (2'). Alternatively, the notched inner race (3) may be force-fitted on an extension (12') of the inner race (2). <IMAGE>

Description

500 10 15 20 25 30 35 2 Innerringen utan spår fasthålles vid intill varandra anordnade löpringar vid ovannämnda delar genom att den har en skuldra mot den andra innerringen. 500 10 15 20 25 30 35 2 The inner ring without grooves is held at adjacent running rings at the above-mentioned parts by having a shoulder against the other inner ring.

Vid på varandra skjutna innerringar är innerringen med spår med presspassning fastsatt på den andra innerringens förlängning. Därigenom onödiggöres den inre skuldran vid innerringen utan spår.In the case of inner rings pushed onto each other, the inner ring with grooves with a press fit is attached to the extension of the other inner ring. This eliminates the need for the inner shoulder of the inner ring without grooves.

Med dessa åtgärder erhålles då för alla lagerdelar en konstruktionsenhet. Buren uppvisar därvid mycket enkel uppbyggnad, och inte heller monteringen bereder några svå- righeter.With these measures, a construction unit is then obtained for all bearing parts. The cage has a very simple construction, and the assembly does not present any difficulties either.

För att kulorna på samma sida som ytterringen med skuldra i den redan inlagda buren skall kunna monteras i ytterringen utan att ramla ut är enligt en ytterligare ut- föringsform av buren på denna sida okavsnitten radiellt förlängda och griper bakom kulorna även om de vid monte- ringen förskjutes radiellt ur sina respektive normallägen.In order for the balls on the same side as the outer ring with shoulder in the already inserted cage to be mounted in the outer ring without falling out, according to a further embodiment of the cage on this side the sections are radially elongated and grip behind the balls even if they are mounted displaced radially from their respective normal positions.

Enligt en ytterligare utföringsform kan buren i sin ringdel i fickornas område uppvisa urtagningar. Därigenom ökas i första hand burens vid monteringen fördelaktiga elasticitet. Vidare åstadkommas ytterligare fettmagasine- ringsrum.According to a further embodiment, the cage can have recesses in its ring part in the area of the pockets. This primarily increases the elasticity of the cage during assembly. Furthermore, additional fat storage spaces are provided.

Uppfinningen skall nu åskådliggöras närmare i anslut- ning till bifogade ritning. Därvid visar fig 1 ett deltvärsnitt genom en lagerkonstruktionsen- het enligt uppfinningen och fig 2 en variant av föremålet enligt fig 1.The invention will now be illustrated in more detail in connection with the accompanying drawing. In this case, Fig. 1 shows a partial cross-section through a bearing construction unit according to the invention and Fig. 2 a variant of the object according to Fig. 1.

Det tvåradiga vinkelkontaktkullagret i O-anordning en- ligt fig 1~består av en endelad ytterring 1, två inner- ringar 2 och 3, en bur 4 och två kulrader 5 och 6. Den förstnämnda uppvisar vid sina axiella ändsidor ingen skuldra.The two-row angular contact ball bearing in O-device according to Fig. 1 ~ consists of a single-part outer ring 1, two inner rings 2 and 3, a cage 4 and two ball rows 5 and 6. The former has no shoulder at its axial end sides.

Innerringen 3 sträcker sig med sin ändyta 3' fram till kul- radens 5 närhet.4 Vid densamma kan därför utan vidare an- spår 7 i vilket insnäppts ett radiellt utsprång 8 på buren 4. I och med detta finns redan en konstruk- tionsenhet innefattande ytterring 1, bur 4, kulrad 6 och För att även kulraden 5 skall fasthållas vid ordnas ett innerring. 10 15 20 25 30 35 3 ovannämnda enhet uppvisar buren 4 på samma sida som kulra- den 5 formen av en kam 9, varvid avsnitt 9' anordnats, vilka griper bakom kulradens 5 kulor. Burens 4 ringdel 4' upp- visar vidare urtagningar 4", vilka gör buren 4 elastisk och åstadkommer magasineringsrum för smörjfett.The inner ring 3 extends with its end surface 3 'up to the proximity of the ball row 5. At the same time, a radial projection 8 on the cage 4 can therefore be easily inserted into it. As a result, there is already a construction unit comprising outer ring 1, cage 4, ball row 6 and In order that the ball row 5 must also be held in place, an inner ring is arranged. The above-mentioned unit has the cage 4 on the same side as the ball row 5 in the form of a cam 9, wherein section 9 'is arranged, which grips behind the balls of the ball row 5. The ring part 4 'of the cage 4 further has recesses 4 ", which make the cage 4 elastic and provide storage space for grease.

Den smala innerringen 2 uppvisar endast en liten skuldra 2', varigenom den fixeras axiellt. Den av samtliga ovan- nämnda delar bestående lagerkonstruktionsenheten kan av lagertillverkaren tillverkas och monteras på enkelt sätt.The narrow inner ring 2 has only a small shoulder 2 ', whereby it is fixed axially. The bearing construction unit consisting of all the above-mentioned parts can be manufactured and assembled by the bearing manufacturer in a simple manner.

Den är därefter lätt att hantera och montera.It is then easy to handle and assemble.

Vid lager med en skuldra 1' vid ytterringens 1 ändsida närmast kulraden 6 är det ändamålsenligt att förse buren 4 med ett radiellt förlängt okavsnitt 11. Vid monteringen kan då radens 6 kulor vika undan radiellt inåt när de skju- tes över den yttre skuldran 1'. För detta erfordras bara att även okavsnitten 11 i denna position griper bakom ku- lorna.In the case of bearings with a shoulder 1 'at the end side of the outer ring 1 closest to the row of balls 6, it is expedient to provide the cage 4 with a radially extended non-section 11. During assembly, the balls 6 of the row 6 can then fold away radially inwards . For this it is only required that even the non-sections 11 in this position grip behind the balls.

I fig 2 visas ett hjullager till ett motorfordon, som har mycket stora likheter med lagret enligt fig 1. Den vä- sentliga skillnaden är begränsad till innerringen utan spår.Fig. 2 shows a wheel bearing for a motor vehicle, which has very large similarities with the bearing according to Fig. 1. The essential difference is limited to the inner ring without grooves.

Den här visade innerringen 12 uppvisar på den ena sidan en förlängning 12', på vilken den andra innerringen 3 påskju- tits. På den andra sidan har integrerats en fastsättnings- fläns 12".The inner ring 12 shown here has on one side an extension 12 ', on which the other inner ring 3 is pushed on. On the other hand, a fastening flange 12 "has been integrated.

Konstruktionsenheten, innefattande ytterringen 1, de båda rullraderna 5 och 6, buren 4 och innerringen 3 uppnås genom de redan i samband med fig 1 beskrivna åtgärderna.The construction unit, comprising the outer ring 1, the two roller rows 5 and 6, the cage 4 and the inner ring 3 is achieved by the measures already described in connection with Fig. 1.

Istället för den lilla skuldran 2' enligt fig 1, som här också är möjlig, anordnas vid innerringen 12 ett fritt ut- rymme 13, speciellt av monteringsskäl. somliga fall ändamålsenligt att tillverka innerringen 12 med fläns på annan plats och att åstadkomma hela enheten I sådana fall möjliggör Det är nämligen i först vid monteringen i maskinen. det fria utrymmet 13 att montera ihop innerringen 12 med de andra lagerdelarna. Hela enheten uppnås här genom att inner- ringen 3 med presspassning placeras på förlängningen 12'.Instead of the small shoulder 2 'according to Fig. 1, which is also possible here, a free space 13 is arranged at the inner ring 12, especially for mounting reasons. In some cases it is expedient to manufacture the inner ring 12 with flange elsewhere and to provide the whole unit. the free space 13 to assemble the inner ring 12 with the other bearing parts. The whole unit is achieved here by placing the inner ring 3 with press fit on the extension 12 '.
